Abstract
The overarching goal of this paper is to examine the efficacy of early intervention when viewed through the lens of developmental neuroscience. We begin by briefly summarizing neural development from conception through the first few postnatal years. We emphasize the role of experience during the postnatal period, and consistent with decades of research on critical periods, we argue that experience can represent both a period of opportunity and a period of vulnerability. Because plasticity is at the heart of early intervention, we next turn our attention to the efficacy of early intervention drawing from two distinct literatures: early intervention services for children growing up in disadvantaged environments, and children at elevated likelihood of developing a neurodevelopmental delay or disorder. In the case of the former, we single out interventions that target caregiving and in the case of the latter, we highlight recent work on autism. A consistent theme throughout our review is a discussion of how early intervention is embedded in the developing brain. We conclude our article by discussing the implications our review has for policy, and we then offer recommendations for future research.

[PMID: 38295654 DOI: 10.1016/j.psyneuen.2023.106949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/22/2023] [Accepted: 12/23/2023] [Indexed: 03/04/2024]
Abstract
BACKGROUND Early life adversity is related to numerous poor health outcomes in childhood; however, dyadic interventions that promote sensitive and responsive caregiving may protect children from the negative consequences of such exposures. To date, quasi-experimental and randomized controlled trials (RCTs) have examined the impact of dyadic interventions on a range of individual biomarkers in children, which may elucidate the relation between early stress exposure and transdiagnostic risk factors for prospective poor health. However, the content of interventions, analytic strategies, and findings vary widely across studies, obscuring key themes in the science and hindering policy and research efforts. METHODS We use a narrative approach to review findings from methodologically rigorous (predominantly RCT) studies of dyadic interventions' impacts on different biomarkers in children, including indicators of the hypothalamic-pituitary-adrenal (HPA) axis, parasympathetic (PNS) and sympathetic nervous systems (SNS), brain development, inflammation, and intracellular DNA processes. We contribute to this important area of inquiry through integrating findings across biological systems and identifying contextual and mechanistic factors to depict the current state of the field. RESULTS Evidence suggests dyadic interventions improved PNS functioning and advanced brain maturation. Some studies indicated interventions reduced hair cortisol concentrations, systemic inflammation, and resulted in differences in DNA methylation patterns. Findings did not support main effect-level change in salivary measures of HPA axis activity, SNS activity, or telomere length. Importantly, reviewed studies indicated significant heterogeneity in effects across biological systems, underscoring the importance of contextual factors (e.g., adversity subtype and severity) as potential moderators of effects. Further, findings suggested enhanced parenting behaviors may be a mechanism through which dyadic interventions operate on biomarkers. CONCLUSIONS We close with future policy and research directions, emphasizing the promise of biologically-informed dyadic interventions for understanding and ameliorating the effects of early adversity on transdiagnostic biomarkers of health.

Abstract
OBJECTIVE Differences in reward processing have been associated with numerous psychiatric disorders, including autism and attention-deficit/hyperactivity disorder (ADHD). Many attempts to understand reward processing characterize differences in clinical populations after disorder onset; however, divergence may begin much earlier. In fact, the typical developmental progression of reward processing in infancy and early childhood is poorly understood. We re-conceptualize classic infant developmental constructs such as preferential looking into a Six-Component Developmental Model of Reward Processing: an infant- and young child-focused framework to guide research and assessment of reward processing across development. METHOD The extant developmental literature including recent textbooks, systematic reviews, and meta-analyses was reviewed to build a conceptual framework. We describe experimental paradigms to assess each developmental component of reward processing longitudinally from infancy. A timeline of each component's emergence was estimated. RESULTS Six components of reward processing were identified-association, discrimination, preference/valuation, effort, anticipation, and response. Selected evidence suggests emergence between birth and 6 months. Application of this model to autism led to a reinterpretation of existing disparate results, and illuminated a path to study the developmental processes underlying a popular hypothesis of autism, the motivation hypothesis. Current evidence further suggests that a sensitive period may exist for the emergence of reward processing. CONCLUSION The proposed framework offers a useful reconceptualization of the extant literature. Future longitudinal work using the suggested experimental paradigms with high-risk populations could elucidate the developmental trajectory of the components and timing of potential sensitive period(s) for each component.

Abstract
Adversity, including abuse, neglect, and poverty, impacts child brain development. However, the developing brain is highly plastic, and some of the impacts of childhood adversity may be mitigated by psychosocial interventions. The purpose of this review is to synthesize literature on neural outcomes of childhood interventions among individuals exposed to adversity. A systematic literature search identified 36 reports of 13 interventions. Overall, these studies provide evidence for experience-dependent plasticity in the developing brain. We synthesize studies in light of three themes. First, there was mixed evidence for a benefit of a younger age at intervention. Second, interventions tended to accelerate functional brain development, but the impact of interventions on the pace of structural brain development was less clear. Third, individual differences in intervention response were difficult to predict, in part due to small samples. However, there was significant variability in intervention type and timing, neuroimaging outcomes, and follow-up timing. Together, the studies reviewed here hold promise for the role of psychosocial interventions in ameliorating the neurodevelopmental consequences of childhood adversity.

Abstract
This editorial discusses where we stand in understanding how parenting interventions, frequently used in the treatment of child emotional and behavioral disorders, affect the brain systems that contribute to these disorders. It concludes that although we have some evidence from RCTs that improving adverse parenting causally impacts some aspects of brain development, there is almost nothing examining parenting randomized controlled trials to treat child clinical disorders and effects on brain structure or function. It argues that if we are to be a brain science, such studies are needed.

Abstract
It was proposed that dimensions of childhood adversity (i.e., deprivation and threat) have distinct effects on neural development and function. Present study examined the relationships between mild deprivation/threat and performance monitoring among undergraduate students without psychiatric diagnoses. By using event-related potentials (ERPs), 78 participants underwent a modified Flanker task in which false feedback on approximately 10% of the correct response trials was administered. The dynamic stages of performance monitoring in this task were differentiated into interference monitoring, feedback processing, and behavior adjustment. Childhood adversity was assessed by a Childhood Trauma Questionnaire (CTQ), which was further divided into subscales of neglect (as a proxy for deprivation dimension) and abuse (as a proxy for threat dimension). Our results showed that higher score of childhood neglect was associated with more interference cost indicated by longer RT to interference trials at the behavioral level, and altered interference monitoring indicated by smaller N2 amplitude to interference trials at the neural level. Meanwhile, higher score of childhood abuse was related to smaller P3 amplitude to unexpected negative feedback. These results suggested that mild childhood deprivation might be associated with altered processing of interference monitoring, while mild childhood threat might be linked to lower electrophysiological response to unexpected negative feedback among young adults without psychiatric disorders.

Abstract
This study examined the impact of a school readiness intervention on external response monitoring in children in foster care. Behavioral and event-related potential (ERP) data were collected during a flanker task from children who received the Kids In Transition to School (KITS) Program (n = 26) and children who received services as usual (n = 19) before and after the intervention. While there were no significant group differences on the behavioral data, the ERP data for the two groups of children significantly differed. Specifically, in contrast to the children who received services as usual, the children who received the KITS Program displayed greater amplitude differences between positive and negative performance feedback over time for the N1, which reflects early attention processes, and feedback-related negativity, which reflects evaluation processes. In addition, although the two groups did not differ on amplitude differences between positive and negative performance feedback for these ERP components before the intervention, the children who received the KITS Program displayed greater amplitude differences than the children who received services as usual after the intervention. These results suggest that the KITS Program had an effect on responsivity to external performance feedback, which may be beneficial during the transition into kindergarten.

Abstract
Children's early language environments are associated with linguistic, cognitive, and academic development, as well as concurrent brain structure and function. This study investigated neurodevelopmental mechanisms linking language input to development by measuring neuroplasticity associated with an intervention designed to enhance language environments of families primarily from lower socioeconomic backgrounds. Families of 52 4-to-6 year-old children were randomly assigned to a 9-week, interactive, family-based intervention or no-contact control group. Children completed pre- and post-assessments of verbal and nonverbal cognition (n = 52), structural magnetic resonance imaging (n = 45), and home auditory recordings of language exposure (n = 39). Families who completed the intervention exhibited greater increases in adult-child conversational turns, and changes in turn-taking mediated intervention effects on language and executive functioning measures. Collapsing across groups, turn-taking changes were also positively correlated with cortical thickening in left inferior frontal and supramarginal gyri, the latter of which mediated relationships between changes in turn-taking and children's language development. This is the first study of longitudinal neuroplasticity in response to changes in children's language environments, and findings suggest that conversational turns support language development through cortical growth in language and social processing regions. This has implications for early interventions to enhance children's language environments to support neurocognitive development.

Abstract
Background Child maltreatment has serious short and long-term negative impacts for those experiencing it. Child maltreatment occurring in institutional settings has recently received substantial attention. However, evidence about the effectiveness of interventions that prevent, disclose, respond to, or treat maltreatment that has occurred in these environments is fragmented and can be difficult to access. This evidence and gap map (EGM) collates this research evidence. It was developed as a resource for stakeholders operating in the child health, welfare and protection sectors, including practitioners, organisational leaders, policy developers and researchers, wanting to access high quality evidence on interventions addressing institutional child maltreatment. Objectives The objectives of this EGM were twofold: (a) To provide a structured and accessible collection of existing evidence from finalised and ongoing overviews of systematic reviews, systematic reviews and effectiveness studies of interventions addressing institutional child maltreatment-for those who work to fund, develop, implement and evaluate interventions aimed at ensuring children's safety in institutional settings; (b) to identify gaps in the available evidence on interventions addressing institutional child maltreatment-thereby helping to inform the research agendas of funders and other organisations. Search Methods A comprehensive search strategy identified relevant studies from published and grey literature, comprising: (1) 10 electronic academic databases; (2) five trial and systematic review registries; (3) nine organisational websites; (4) websites and reference lists of inquiry reports associated with seven international inquiries into child abuse and (4) the lists of included studies within systematic reviews identified by the search strategy. Members of this EGM's Subject Matter Experts group were also invited to forward relevant unpublished studies or grey literature. Selection Criteria The selection criteria were developed to identify finalised and ongoing overviews of reviews, systematic reviews and primary studies that reported on the effectiveness of interventions addressing child maltreatment (including sexual abuse, physical abuse, neglect and emotional abuse) within institutional settings. Eligible effectiveness study designs included: randomised controlled trials (RCTs), nonrandomised trials, controlled before-and-after studies and quasi-experimental studies. Reviews were eligible if they reported a systematic literature search strategy. Data Collection and Analysis All screening, data extraction, coding and critical appraisals were undertaken by two or more reviewers working independently, with discrepancies resolved via consensus or by a third reviewer. The titles and abstracts of studies identified by the search strategy were screened, and each full text of potentially relevant studies was further assessed for inclusion. Key data were extracted from all included studies and reviews. This included information about: publication details (e.g., year, author, country), inclusion/exclusion criteria (for reviews), study design, institutional setting, target population, type of maltreatment, intervention type and outcomes. Critical appraisal of included systematic reviews was achieved using the AMSTAR 2 tool, and completed RCTs were assessed using the updated Cochrane Risk of Bias 2.0 tool. Main Results Number of studies The electronic database search yielded 6318 citations, and a further 2375 records were identified from additional sources. Following deduplication and title/abstract screening, 256 studies remained for full text review. A total of 73 eligible studies (reported across 84 publications) met the inclusion criteria, including: 11 systematic reviews (plus, one update); 62 primary studies (including, three protocols for primary studies). Study characteristics The studies were conducted across 18 countries, however more than half (52%) were undertaken in the United States. Overall, most studies evaluated curriculum-based interventions delivered in educational settings, primarily aimed at the prevention of sexual abuse. Institutional setting: Most studies evaluated interventions in school or early learning environments (n = 8 systematic reviews; n = 58 primary studies). Far fewer studies examined other organisational settings. Out of home care (including foster care, residential care and orphanages), and social service organisations servicing children were minimally represented. No studies were identified where the primary setting was sports clubs, churches/religious organisations, summer/vacation camps, detention centres/juvenile justice settings, or primary/secondary health care facilities. Target population: Most interventions targeted children rather than adults (n = 7 systematic reviews; n = 47 primary studies) from the general population. Fewer studies included populations known to be at an increased risk, or those already exposed to maltreatment. Just over a third of the primary studies conducted an analysis to ascertain differences in the effect of an intervention between the genders. Intervention type: Prevention interventions were the most studied (n = 5 systematic reviews; n = 57 primary studies), with additional studies including prevention approaches alongside other intervention types. Fewer studies evaluated interventions targeting disclosure, institutional responses, or treatment interventions. Type of maltreatment: The vast majority of the studies assessed interventions solely addressing the sexual abuse of children (n = 8 systematic reviews; n = 45 primary studies). The remaining studies addressed other forms of maltreatment, including physical and emotional abuse, or neglect, either in combination or as a sole focus. Outcomes: Primary reported outcomes reflected the bias toward child targeted interventions. Outcome measures captured child wellbeing and knowledge outcomes, including measures of mental health, children's knowledge retention and/or self-protective skills. Measures of maltreatment disclosure or maltreatment occurrence/reoccurrence were less common, and all other outcome categories included in the EGM were minimally or not reported. A third of studies reported on some measure of implementation. Study quality The overall quality of the studies was low to moderate. Most systematic reviews were low-quality (n = 10), with only one high quality review (and update) identified. Most completed RCTs had some concerns relating to the risk of bias (n = 30), and the remainder were considered to be at a high risk of bias (n = 19). Authors' Conclusions This EGM has highlighted a substantial need for more high quality studies that evaluate interventions across a broader range of institutional contexts and maltreatment types. The current evidence base does not represent countries with large populations and the greatest incidence of child maltreatment. Few studies focussed on perpetrators or the organisational environment. Further evidence gaps were identified for interventions relating to disclosure, organisational responses and treatment, and few studies assessed interventions targeting perpetrators' maltreatment behaviours, recidivism or desistence. Future studies should also include measure of programme implementation.

Abstract
There is an extensive literature describing the detrimental effects of adverse childhood experiences (ACE; e.g., abuse, neglect, and household dysfunction) on physical and mental health. However, few large-scale studies have explored these associations longitudinally in urban minority cohorts or assessed links to broader measures of well-being such as educational attainment, occupation, and crime. Although adversity and resilience have long been of interest in developmental psychology, protective and promotive factors have been understudied in the ACE literature. This paper investigates the psychosocial processes through which ACEs contribute to outcomes, in addition to exploring ways to promote resilience to ACEs in vulnerable populations. Follow-up data were analyzed for 87% of the original 1,539 participants in the Chicago Longitudinal Study (N = 1,341), a prospective investigation of the impact of an Early Childhood Education program and early experiences on life-course well-being. Findings suggest that ACEs impact well-being in low-socioeconomic status participants above and beyond the effects of demographic risk and poverty, and point to possible mechanisms of transmission of ACE effects. Results also identify key areas across the ecological system that may promote resilience to ACEs, and speak to the need to continue to support underserved communities in active ways.

Abstract
AbstractAs a result of maltreatment, children in care can present with a range of complex needs and challenges. In addition to direct clinical care commonly provided by paediatricians, psychiatrists, and clinical psychologists, the provision of knowledge and skills to foster and kinship carers have become modes of support common in responding to these needs and challenges. A narrative review of key systematic reviews and empirical research was conducted to assess the effectiveness of existing foster carer interventions. Results indicated a range of methodological characteristics that limit our ability to develop a sound, research-driven, evidence base. As a result, we remain limited in our knowledge about which treatments are effective, for which symptoms they are effective, and for which population subgroups they are most likely to be effective. This review provides a summary of identified needs and challenges in the delivery of foster carer interventions. It provides an account of current treatment components and offers a platform for the development and progression of a programme of research in an effort to advance knowledge in the area.

Abstract
Early institutional-deprivation has been found to increase risk for inattention/hyperactivity (ADHD). Notably, studies suggest that children with a history of adversity evidencing an enhanced ERP (the error-related-negativity; ERN) may be protected against attention problems. However, such protective effects of the ERN have been studied in children whom typically experienced residential instability. It is unknown whether error-monitoring is similarly protective for children with stable post-deprivation placements. The present study examined the protective effect of the ERN in a sample of children who experienced at least 3-years of stable, relatively enriched caregiving after being internationally-adopted as infants/toddlers from institutional-care. We included two groups of children adopted internationally before age three, one group adopted from institutional-care (PI:n = 80) and one comparison group adopted from foster-care (FC;n = 44). A second comparison group consisted of non-adopted children (NA;n = 48) from demographically comparable families. At five-years of age, we assessed child ADHD symptoms (parent-report) and behavioral performance and neural correlates of error-monitoring (Go/No-Go task). PI children displayed lower Go/No-Go accuracy relative to FC children, and higher levels of ADHD symptoms relative to NA controls. In both FC and PI groups, longer duration of pre-adoptive out-of-home placement was associated with inattention, especially for children with deficits in error-monitoring. Enhancing cognitive control in the form of error monitoring might be a useful intervention target to protect children from some of the negative outcomes associated with adverse early care. Furthermore, results underscore that regardless of type of pre-adoptive care, we should aim to place children in stable/permanent homes as early as possible.

Abstract
Neuroscientific tools and approaches such as neuroimaging, measures of neuroendocrine and psychoneuroimmune activity, and peripheral physiology are increasingly used in clinical science and health psychology research. We define translational neuroscience (TN) as a systematic, theory-driven approach that aims to develop and leverage basic and clinical neuroscientific knowledge to aid the development and optimization of clinical and public health interventions. There is considerable potential across basic and clinical science fields for this approach to provide insights into mental and physical health pathology that had previously been inaccessible. For example, TN might hold the potential to enhance diagnostic specificity, better recognize increased vulnerability in at-risk populations, and augment intervention efficacy. Despite this potential, there has been limited consideration of the advantages and limitations of such an approach. In this article, we articulate extant challenges in defining TN and propose a unifying conceptualization. We illustrate how TN can inform the application of neuroscientific tools to realistically guide clinical research and inform intervention design. We outline specific leverage points of the TN approach and barriers to progress. Ten principles of TN are presented to guide and shape the emerging field. We close by articulating ongoing issues facing TN research. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
Research on the effects of early life adversity, and in particular on the absence of responsive caregiving, has shown long-term impacts on well-being and development. These investigations have been conducted both in human populations and in animal models. The work has demonstrated that neglect experienced in the early years can affect not only behavior but also neurobiological functioning. In particular, studies of children in the foster care system show convergence with research on children adopted following institutional rearing in terms of dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which produces the neuroendocrine hormone cortisol. The characteristic pattern that has been most commonly observed involves diminished diurnal cortisol production, particularly in terms of low levels of cortisol upon awakening. Notably, however, a number of evidence-based interventions for infant, toddler, and preschool-aged foster children have been shown to produce more typical patterns of cortisol production, in combination with improved behavioral, socioemotional, and foster care placement outcomes. In this paper, we review the literature on the effects of early disruptions in care on biobehavioral development, and summarize the results of the interventions for young foster children.

Influence of speech-language therapy on P300 outcome in patients with language disorders: a meta-analysis. Braz J Otorhinolaryngol 2019; 85:510-519. [PMID: 30902588 PMCID: PMC9443043 DOI: 10.1016/j.bjorl.2019.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Revised: 10/03/2018] [Accepted: 01/02/2019] [Indexed: 11/22/2022] Open
Abstract
Introduction The patient's evolution in the audiology and speech-language clinic acts as a motivator of the therapeutic process, contributing to patient adherence to the treatment and allowing the therapist to review and/or maintain their clinical therapeutic conducts. Electrophysiological measures, such as the P300 evoked potential, help in the evaluation, understanding and monitoring of human communication disorders, thus facilitating the prognosis definition in each case. Objective To determine whether the audiology and speech-language therapy influences the variation of P300 latency and amplitude in patients with speech disorders undergoing speech therapy. Methods This is a systematic review with meta-analysis, in which the following databases were searched: Pubmed, ScienceDirect, SCOPUS, Web of Science, SciELO and LILACS, in addition to the gray literature bases: OpenGrey.eu and DissOnline. The inclusion criteria were randomized or non-randomized clinical trials, without language or date restriction, which evaluated children with language disorders undergoing speech therapy, monitored by P300, compared to children without intervention. Results The mean difference between the latencies in the group submitted to therapy and the control group was −20.12 ms with a 95% confidence interval of −43.98 to 3.74 ms (p = 0.08, I2 = 25% and p value = 0.26). The mean difference between the amplitudes of the group submitted to therapy and the control group was 0.73 uV with a 95% confidence interval of −1.77 to 3.23 uV (p = 0.57, I2 = 0% and p value = 0.47). Conclusion The present meta-analysis demonstrates that speech therapy does not influence the latency and amplitude results of the P300 evoked potential in children undergoing speech therapy intervention.

Abstract
BACKGROUND Growing work points to the negative impact of early adverse experiences on the developing brain. An outstanding question concerns the extent to which early intervention can normalize trajectories of brain development in at-risk children. We tested this within the context of a randomized clinical trial of an early parenting program, the Attachment and Biobehavioral Catch-up (ABC), delivered to parents and infants monitored for maltreatment by Child Protective Services. METHODS Families participated in the randomized clinical trial when children were 2.5 years of age or younger. Parenting and home adversity was measured at baseline. Children were followed longitudinally, and resting brain activity was measured electrophysiologically (n = 106) when children reached 8 years of age. Spectral power was quantified and compared across children assigned to the experimental intervention (ABC), a control intervention, and a low-risk comparison group (n = 76) recruited at the follow-up assessment. RESULTS Higher early home adversity was associated with electrophysiological profiles indicative of cortical delays/immaturity in middle childhood, based on relatively greater power in lower frequency bands (theta, 4-6 Hz, and low alpha, 6-9 Hz) and lower power in a higher frequency band (high alpha, 9-12 Hz). Children assigned to ABC showed relatively greater high-frequency power (beta, 12-20 Hz) than children assigned to the control intervention. Beta power in the ABC did not differ from that of the low-risk comparison group. CONCLUSIONS Maltreatment risk and home adversity can affect indicators of middle childhood brain maturation. Early parenting programs can support more normative patterns of neural function during middle childhood.

Abstract
Substance use and addiction are disproportionately experienced by individuals with a history of exposure to early life stress (ELS), such as maltreatment, domestic violence and parent psychopathology. Unfortunately, extant interventions have mixed effectiveness at improving outcome trajectories for ELS-exposed children, who are often underserved by evidenced-based programs. Here, we employ a translational neuroscience framework to delineate how neuroscience can deepen our understanding of ELS-linked alterations in children's function to inform the development of more targeted, effective early intervention and addiction prevention programs. Candidate neural pathways altered by ELS and linked to addiction are described across sensory, affective, motivational, and executive function domains. Next, we provide an example of the application of translational neuroscience principles in a family of early interventions (i.e. Multidimensional Treatment Foster Care – Preschool, Kids in Transition to School) focused on improving self-regulation in ELS-exposed children. Future directions and areas of unmet need in intervention research detail the significant potential of translational neuroscience to advance interventionists' ability to support positive adjustment in ELS-exposed children and prevent harmful addiction outcomes.

Abstract
Among children diagnosed with developmental delays, difficulties in self-regulation are prominent and have been linked to school readiness problems. The current study sought to examine the impact of the Kids in Transition to School (KITS) school readiness intervention program on self-regulation, with a specific focus on response monitoring skills, among children with developmental delays. Children (n = 20 in the KITS group and n = 21 in a services as usual group) were administered a flanker task during which event-related potential data were collected to examine group differences in response monitoring. Findings indicated that children in the KITS group showed significant enhancement of a neural index of response monitoring post-intervention. Specifically, the KITS group showed a significant change in the magnitude of their feedback-related negativity in response to negative performance feedback from baseline to post-intervention, whereas children in the services as usual group did not. There were no significant differences between the groups for the error-related negativity or the error-related positivity on incorrect trials nor were there group differences in behavioral performance on the task at the post-intervention assessment. Overall, these findings provide support for the plasticity of response monitoring skills in young children and support the growing literature demonstrating improved self-regulation outcomes via intervention that enhances children's response monitoring.

Abstract
Institutional rearing is associated with deficits in executive functions, such as inhibitory control, and may contribute to later externalizing behavior problems. In the current study, we explored the impact of institutional rearing on attention in the context of inhibiting a planned action. As part of the Bucharest Early Intervention Project (BEIP), children were randomized to either remain in the institutions in which they lived (Care as Usual Group) or be placed into foster family homes (Foster Care Group). We also recruited age and gender matched never-institutionalized (NIG) children from the Bucharest community. We examined differences in behavioral and Event Related Potentials (ERPs) during a go-no-go task when children were 12 years old. Results revealed that the ever-institutionalized group (CAUG and FCG combined) showed slower reaction times, worse performance accuracy, larger P2 activation, and smaller (less negative) N2 activation than the NIG group. Results of a moderation analysis revealed that children who spent more time in institutions and had small N2s showed more externalizing symptoms. These results have implications for the design of treatment approaches for previously institutionalized children with externalizing behavior problems.

Abstract
OBJECTIVE Reward positivity (RewP), a neurophysiologic index of reward responsivity, is consistently reduced in participants with depression and, to a lesser extent, anxiety. It remains unknown, however, whether RewP can be altered as psychiatric symptoms change with treatment. The current study addressed this question by examining differences in RewP within patients before and after 12 weeks of treatment with a selective serotonin reuptake inhibitor (SSRI) or cognitive-behavioral therapy (CBT). We also examined the utility of RewP as a predictor of symptom change during CBT and SSRI treatment. METHODS Participants were recruited between 2014 and 2017 and included adults with a primary DSM-5 anxiety or depressive disorder (n = 63) and healthy controls (n = 25). At baseline and 12 weeks, participants completed a monetary award task while electroencephalogram (EEG) was recorded. Between EEG sessions, patients completed CBT or SSRI treatment. RESULTS At baseline, higher levels of depressive symptoms were associated with a more attenuated RewP. We found no significant differences between patients and healthy controls in the degree of RewP change across the 12 weeks; however, among patients, the extent of increase in RewP robustly correlated with the extent of decline in depressive (t = -2.21, P = .03) and anxiety (t = -2.57, P = .02) symptoms following CBT and SSRI treatment. Additionally, a more attenuated RewP at baseline predicted a greater reduction in depressive symptoms following treatment with SSRIs (t = -2.04, P < .05), but not after CBT. CONCLUSIONS These findings highlight neural responsiveness to reward as both a mechanism and a predictor of depressive symptom change that may be used serve as an objective index of symptom improvement.

Abstract
BACKGROUND Child maltreatment is a substantial social problem that affects large numbers of children and young people in the UK, resulting in a range of significant short- and long-term psychosocial problems. OBJECTIVES To synthesise evidence of the effectiveness, cost-effectiveness and acceptability of interventions addressing the adverse consequences of child maltreatment. STUDY DESIGN For effectiveness, we included any controlled study. Other study designs were considered for economic decision modelling. For acceptability, we included any study that asked participants for their views. PARTICIPANTS Children and young people up to 24 years 11 months, who had experienced maltreatment before the age of 17 years 11 months. INTERVENTIONS Any psychosocial intervention provided in any setting aiming to address the consequences of maltreatment. MAIN OUTCOME MEASURES Psychological distress [particularly post-traumatic stress disorder (PTSD), depression and anxiety, and self-harm], behaviour, social functioning, quality of life and acceptability. METHODS Young Persons and Professional Advisory Groups guided the project, which was conducted in accordance with Cochrane Collaboration and NHS Centre for Reviews and Dissemination guidance. Departures from the published protocol were recorded and explained. Meta-analyses and cost-effectiveness analyses of available data were undertaken where possible. RESULTS We identified 198 effectiveness studies (including 62 randomised trials); six economic evaluations (five using trial data and one decision-analytic model); and 73 studies investigating treatment acceptability. Pooled data on cognitive-behavioural therapy (CBT) for sexual abuse suggested post-treatment reductions in PTSD [standardised mean difference (SMD) -0.44 (95% CI -4.43 to -1.53)], depression [mean difference -2.83 (95% CI -4.53 to -1.13)] and anxiety [SMD -0.23 (95% CI -0.03 to -0.42)]. No differences were observed for post-treatment sexualised behaviour, externalising behaviour, behaviour management skills of parents, or parental support to the child. Findings from attachment-focused interventions suggested improvements in secure attachment [odds ratio 0.14 (95% CI 0.03 to 0.70)] and reductions in disorganised behaviour [SMD 0.23 (95% CI 0.13 to 0.42)], but no differences in avoidant attachment or externalising behaviour. Few studies addressed the role of caregivers, or the impact of the therapist-child relationship. Economic evaluations suffered methodological limitations and provided conflicting results. As a result, decision-analytic modelling was not possible, but cost-effectiveness analysis using effectiveness data from meta-analyses was undertaken for the most promising intervention: CBT for sexual abuse. Analyses of the cost-effectiveness of CBT were limited by the lack of cost data beyond the cost of CBT itself. CONCLUSIONS It is not possible to draw firm conclusions about which interventions are effective for children with different maltreatment profiles, which are of no benefit or are harmful, and which factors encourage people to seek therapy, accept the offer of therapy and actively engage with therapy. Little is known about the cost-effectiveness of alternative interventions. LIMITATIONS Studies were largely conducted outside the UK. The heterogeneity of outcomes and measures seriously impacted on the ability to conduct meta-analyses. FUTURE WORK Studies are needed that assess the effectiveness of interventions within a UK context, which address the wider effects of maltreatment, as well as specific clinical outcomes.

Abstract
Prior research has identified the presence of executive function (EF) deficits in child protective service (CPS) involved (versus non-involved) children but minimal work has examined predictors that might explain individual differences within these CPS-involved children. Here, we sought to characterize EF in a large sample (N=694) of CPS-involved children and examine how specific adversities (physical abuse, neglect, caregiver domestic violence, and caregiver substance dependence) and cumulative adversity (at ages 0-3 and 3-6 years) predict EF (at approximately 5-6 years). It was expected that the sample would exhibit low EF overall based on previous research in maltreated children. Specific adversity and cumulative adversity analyses were largely exploratory given the limited previous work in this area. Results indicated poor EF overall, with 43.5% of children performing worse than chance. Amongst children who performed greater than chance, higher cumulative adversity, physical abuse, and caregiver substance use (at ages 3-6 years) predicted better EF. These findings join literature documenting that, within CPS-involved children, the presence of certain adversities predicts variable cognitive function. Findings highlight the potential relevance of evolutionary psychology to understanding how alterations in behavior linked to harsh and unpredictable early environments may cue accelerated brain development underlying relative cognitive advantages, within at-risk, low performing samples. Longitudinal studies are critical to determine if the relative EF advantages linked to higher adversity persist over time or result in lower EF later on, reflecting a more rapid, but overall limited, trajectory of cognitive development.

Abstract
OBJECTIVE Children in foster care are at greater risk for poor health, physical, cognitive, behavioral, and developmental outcomes than are children in the general population. Considerable research links early nutrition to later cognitive and behavioral outcomes. The aim of this narrative review is to examine the prevalence of poor nutrition and its relation to subsequent health and development in foster children. METHOD Relevant studies for inclusion were identified from numerous sources (e.g., PubMed, Google Scholar, and reference sections). Inclusion criteria were studies published between 1990 and 2016 of (i) the nutritional status of children in foster care or (ii) the nutritional status of children exposed to early adversity (e.g., low-income and internationally adopted children) or (iii) the developmental effects of poor nutrition and micronutrient deficiencies. RESULTS Two key findings that have adverse implications for cognitive development emerged: (i) the prevalence of anemia and iron-deficiency anemia is higher among foster children than among the general population of children in the U.S., and (ii) the developmental demands of catch-up growth post-placement may lead to micronutrient deficiencies even after children have begun sufficient dietary intake of these nutrients. Moreover, there is a paucity of recent studies on the nutritional status of children in foster care, despite the multiple factors that may place them at risk for malnutrition. CONCLUSION Attention to nutritional status among care providers and medical professionals may remove one of the possible negative influences on foster children's development and in turn significantly alter their trajectories and place them on a more positive path early in life. Recommendations for further research, policy, and practice are discussed.

Abstract
The use of theory-driven models to develop and evaluate family-based intervention programs has a long history in psychology. Some of the first evidence-based parenting programs to address child problem behavior, developed in the 1970s, were grounded in causal models derived from longitudinal developmental research. The same translational strategies can also be applied to designing programs that leverage emerging scientific knowledge about the effects of early adverse experiences on neurobiological systems to reduce risk and promote well-being. By specifying not only behavioral targets but also affected underlying neural systems, interventions can become more precise and efficient. This chapter describes the development of a program of research focusing on an intervention for young children in foster care. The intervention emerged from social learning theory research and employs a translational neuroscience approach. The conceptual model guiding the research, which incorporates behavioral domains as well as stress-regulatory neural systems, is described. Finally, future directions for translational neuroscience in family-based intervention research are considered.

Abstract
In this article, we focus on applying methods of translational neuroscience to two-generation, family-based interventions. In recent years, a small but growing body of evidence has documented the reversibility of some of the neurobiological effects of early adversity in the context of environmental early interventions. Some of these interventions are now being implemented at scale, which may help reduce disparities in the face of early life stress. Further progress may occur by extending these efforts to two-generation models that target caregivers' capabilities to improve children's outcomes. In this article, we describe the content and processes of the Filming Interactions to Nurture Development (FIND) video coaching intervention. We also discuss the two-generation, translational neuroscience framework on which FIND is based, and how similar approaches can be developed and scaled to mitigate the effects of adversity.

Abstract
Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event-related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty-six demographically similar adolescents (ages 9-14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (n = 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (n = 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (n = 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment-related effects on these neural systems.

Abstract
Children exposed to various forms of adversity early in life are at increased risk for a broad range of developmental difficulties, affecting both cognitive and emotional adjustment. We review a growing body of evidence suggesting that exposure to adverse circumstances affects the developing brain in ways that increase risk for a myriad of problems. We focus on two forms of adversity, one in which children are exposed to childhood maltreatment in family environments, and another in which children are exposed to extreme psychosocial deprivation in contexts of institutional rearing. We discuss ways in which each of these experiences represent violations of species-expected caregiving conditions, thereby imposing challenges to the developing brain. We also review emerging data pointing to the effectiveness of early intervention in remediating neurodevelopmental consequences associated with maltreatment or institutional rearing. We conclude by discussing implications of this work for public health efforts and highlight important directions for the field.

Abstract
Identifying neurocognitive processes associated with effective inhibitory control is particularly relevant for individuals at high risk for disruptive behaviors, such as maltreated children. Performance feedback processing during a flanker task was investigated in maltreated preschool-aged children (N = 67) via an event-related potential component, the feedback-related negativity (FRN). The functionality of the FRN in children with high impulsivity was of interest, as impulsivity was associated with an exaggerated FRN in previous research. Results showed that high impulsivity was associated with an exaggerated FRN and greater post-error slowing. For children with high impulsivity, there was a correlation between the FRN and accuracy, which was not found in children with low impulsivity. This suggests that an exaggerated FRN is particularly important for children with high impulsivity to maintain effective inhibitory control.

Abstract
BACKGROUND This review of the literature examines adoption, fostering, and the needs of looked-after and adopted children. Three domains of research about looked-after children are examined. FINDINGS There is extensive evidence that early adverse experiences affect psychological and neurobiological development in looked-after and adopted children. There is also evidence that some looked-after and adopted children show remarkable resilience in the face of adversity; intervention research provides evidence of the ability to reduce risks and promote positive outcomes in this population. The intervention studies have revealed not only the potential for improved behavioral trajectories but also the plasticity of neurobiological systems affected by early stress. CONCLUSION Foster and adopted children face many challenges, but scientific knowledge also provides reason for hope and information about how to maximize positive outcomes.

Abstract
BACKGROUND A neurobiological perspective has become accepted as a valuable approach for understanding anti-social behaviour. There is literature to suggest that, in non-offending populations, psychological treatments affect both neurobiological measures and clinical presentation. A theoretical position to this effect has been adopted with respect to offender treatment, but there has been no systematic review of empirical literature on this point. AIMS This study aimed to ascertain from published literature firstly whether there is evidence of change in neuropsychological or physiological measures after behavioural treatments/programmes for people with anti-social behaviour and secondly whether these neurobiological changes are associated with behavioural change. METHOD A systematic search strategy was formulated to include studies considering 'neurobiological factors', 'anti-social population', 'treatment' and 'treatment outcome'. The Maryland Scientific Methods Scale was used to select relevant studies of sufficient methodological quality. RESULTS Eleven studies were found, only one with adults. Overall, the values of specific neurobiological risk factors, particularly of basal cortisol, become less abnormal following intervention. There was some evidence for a link between change in neurobiological functioning and behavioural improvement. CONCLUSIONS Findings, although provisional, may provide new insights into the underlying mechanisms of interventions for anti-social behaviour. Future studies that include pre-treatment neurobiological assessment could help reveal physical vulnerabilities that interventions should target to improve treatment efficacy, and provide for objective, independent corroboration of change.

Abstract
Effective early education is essential for academic achievement and positive life outcomes, particularly for children in poverty. Advances in neuroscience suggest that a focus on self-regulation in education can enhance children's engagement in learning and establish beneficial academic trajectories in the early elementary grades. Here, we experimentally evaluate an innovative approach to the education of children in kindergarten that embeds support for self-regulation, particularly executive functions, into literacy, mathematics, and science learning activities. Results from a cluster randomized controlled trial involving 29 schools, 79 classrooms, and 759 children indicated positive effects on executive functions, reasoning ability, the control of attention, and levels of salivary cortisol and alpha amylase. Results also demonstrated improvements in reading, vocabulary, and mathematics at the end of kindergarten that increased into the first grade. A number of effects were specific to high-poverty schools, suggesting that a focus on executive functions and associated aspects of self-regulation in early elementary education holds promise for closing the achievement gap.

Abstract
Childhood adversity is associated with physiologic dysregulation across multiple biological systems; however, relatively little is known about whether these changes are reversible with intervention. The objective of this review was to examine evidence for the effectiveness of interventions to promote healthy cortisol regulation in children. We selected articles from English-language publications in PubMed and EBSCO databases through 2012. Two independent reviewers assessed articles against eligibility criteria. Eligible studies were randomized controlled or quasi-experimental studies designed to improve relationships, environments, or psychosocial functioning in children and examined cortisol as an outcome. We identified 19 articles. There was substantial heterogeneity across studies with regard to age, selection criteria, intervention design, cortisol assessment, and follow-up duration. Eighteen of the 19 articles reported at least 1 difference in baseline cortisol, diurnal cortisol, or cortisol responsivity between intervention and control participants. Importantly, however, there was remarkable inconsistency with regard to how the interventions influenced cortisol. Therefore, studies that included a low-risk comparison group (n = 8) provided critical insight, and each found some evidence that postintervention cortisol levels in the intervention group approximated the low-risk comparison group and differed from children receiving usual care. In conclusion, existing studies show that cortisol activity can be altered by psychosocial interventions. These findings are promising, not only because they indicate physiologic plasticity that can be leveraged by interventions but also because they suggest it may be possible to repair regulatory systems after childhood adversity, which could inform strategies for reducing health disparities and promoting lasting improvements in health.

Abstract
Half a century of research and program evaluation has fueled a diverse landscape of early childhood policies and practices that produce a range of positive effects on the life prospects of children who face the burdens of significant adversity. Drawing on advances in neurobiology, developmental psychology, developmental psychopathology, and prevention science, this paper presents a framework for elucidating underlying causal mechanisms that explain differences in outcomes, formulating enhanced theories of change about how to shift developmental trajectories, designing creative interventions and rethinking the concept of a two-generation strategy to produce breakthrough impacts, and launching a new era of investment in young children and their families that will achieve greater reductions in intergenerational disparities in learning, behavior, and health than those produced by current best practices. Particular attention is focused on the hypothesis that substantially better outcomes for vulnerable, young children could be achieved by greater attention to strengthening the resources and capabilities of the adults who care for them rather than by continuing to focus primarily on the provision of child-focused enrichment, parenting education, and informal support. Central to achieving this goal is the need to establish an innovation-friendly environment that embraces fast-cycle sharing, supports risk taking, and celebrates learning from failure.

Abstract
Children in foster care have often encountered a range of adverse experiences, including neglectful and/or abusive care and multiple caregiver transitions. Prior research findings suggest that such experiences negatively affect inhibitory control and the underlying neural circuitry. In the current study, event-related functional magnetic resonance imaging was employed during a go/no go task that assesses inhibitory control to compare the behavioral performance and brain activation of foster children and nonmaltreated children. The sample included two groups of 9- to 12-year-old children: 11 maltreated foster children and 11 nonmaltreated children living with their biological parents. There were no significant group differences on behavioral performance on the task. In contrast, patterns of brain activation differed by group. The nonmaltreated children demonstrated stronger activation than did the foster children across several regions, including the right anterior cingulate cortex, the middle frontal gyrus, and the right lingual gyrus, during correct no go trials, whereas the foster children displayed stronger activation than the nonmaltreated children in the left inferior parietal lobule and the right superior occipital cortex, including the lingual gyrus and cuneus, during incorrect no go trials. These results provide preliminary evidence that the early adversity experienced by foster children impacts the neural substrates of inhibitory control.

Abstract
Children join adoptive families through domestic adoption from the public child welfare system, infant adoption through private agencies, and international adoption. Each pathway presents distinctive developmental opportunities and challenges. Adopted children are at higher risk than the general population for problems with adaptation, especially externalizing, internalizing, and attention problems. This review moves beyond the field's emphasis on adoptee-nonadoptee differences to highlight biological and social processes that affect adaptation of adoptees across time. The experience of stress, whether prenatal, postnatal/preadoption, or during the adoption transition, can have significant impacts on the developing neuroendocrine system. These effects can contribute to problems with physical growth, brain development, and sleep, activating cascading effects on social, emotional, and cognitive development. Family processes involving contact between adoptive and birth family members, co-parenting in gay and lesbian adoptive families, and racial socialization in transracially adoptive families affect social development of adopted children into adulthood.

Abstract
Foster care is a complex setting in which to provide therapeutic interventions due to the high rates of difficulty, poor outcomes and high numbers of professionals and carers involved. This systematic review aims to examine interventions that have been empirically assessed in foster care. Thirty papers describing 20 interventions were included. It was found that there was good support for wraparound services and relational interventions, but little support for widely used carer training programmes. A need was identified to further research and implement wraparound services within the UK, and to empirically test interventions which may be efficacious with a foster care population.

Abstract
Early psychosocial deprivation can negatively impact the development of executive functions (EFs). Here we explore the impact of early psychosocial deprivation on behavioral and physiological measures (i.e., event-related potentials; ERPs) of two facets of EF, inhibitory control and response monitoring, and their associations with internalizing and externalizing outcomes in the Bucharest Early Intervention Project (BEIP; Zeanah et al., 2003). This project focuses on two groups of children placed in institutions shortly after birth and then randomly assigned in infancy to either a foster care intervention or to remain in their current institutional setting. A group of community controls was recruited for comparison. The current study assesses these children at 8-years of age examining the effects of early adversity, the potential effects of the intervention on EF and the role of EF skills in socio-emotional outcomes. Results reveal exposure to early psychosocial deprivation was associated with impaired inhibitory control on a flanker task. Children in the foster care intervention exhibited better response monitoring compared to children who remained in the institution on the error-related positivity (Pe). Moreover, among children in the foster care intervention those who exhibited larger error-related negativity (ERN) responses had lower levels of socio-emotional behavior problems. Overall, these data identify specific aspects of EF that contribute to adaptive and maladaptive socio-emotional outcomes among children experiencing early psychosocial deprivation.

Abstract
Placement instability is a common occurrence among foster children and others involved with child welfare system services, and is associated with negative psychiatric and mental health outcomes. The purpose of this paper is to review and synthesize research in this area and to consider this information in terms of child welfare practice and policy. Evidence from 59 sources is reviewed, including research on (a) the connection between placement instability and poor outcomes; (b) sources of information that can be employed to reliably predict risk for placement instability; and (c) interventions designed to mitigate the effects of placement instability. The available empirical evidence suggests that placement instability and other family chaos is associated with disrupted development of the brain’s prefrontal cortex, which is involved in executive functioning. Poor executive functioning is implicated in elevated risk for ADHD, disruptive behavior disorders, substance abuse, and other forms of disinhibitory psychopathology. This might help to explain the high rates of psychiatric medication prescriptions for foster children. Notably, however, recent research findings have shown that placement instability is both predictable and preventable and that interventions to address placement instability have the potential to mitigate neurobiological and psychiatric effects of prior adversity.

Abstract
Self-control plays an important role in healthy development and has been shown to be amenable to intervention. This article presents a theoretical framework for the emerging area of "brain-training" interventions that includes both laboratory-based direct training methods and ecologically valid school-, family-, and community-based interventions. Although these approaches have proliferated in recent years, evidence supporting them is just beginning to emerge, and conceptual models underlying many of the techniques they employ tend to be underspecified and imprecise. Identifying the neural systems responsible for improvements in self-control may be of tremendous benefit not only for overall intervention efficacy but also for basic science issues related to underlying shared biological mechanisms of psychopathology. This article reviews the neurodevelopment of self-control and explores its implications for theory, intervention, and prevention. It then presents a neurally informed framework for understanding self-control development and change and discusses how this framework may inform future intervention strategies for individuals suffering with psychopathology or drug abuse/dependence, or for young children with delays in cognitive or emotional functioning.

Abstract
BACKGROUND An increasing number of children are placed in foster care (i.e., a kin or nonkin family home other than the biological parent) due to experiences of physical, sexual, emotional, or psychological abuse, and/or neglect. Children in foster care are at increased risk for a host of negative outcomes encompassing emotional, behavioral, neurobiological, and social realms. METHODS Areas of risk and vulnerability among foster children are described, including emotional and behavioral deficits, impaired neurobiological development, and social relationship deficits. Evidence suggesting the significance of family placement changes and prenatal exposure to substances as contributing mechanisms is presented. Based on a systematic search of the PsycINFO database (to March 2012), eight efficacious evidence-based interventions for foster families are summarized. FINDINGS Although the development of evidence-based interventions that improve outcomes for foster children has lagged behind the delivery of interventions in other service sectors (e.g., mental health and educational sectors), several interventions across childhood and adolescence offer promise. Service system constraints offer both challenges and opportunities for more routine implementation of evidence-based interventions. CONCLUSIONS Given the increased likelihood of poor outcomes for foster children, increased efforts to understand the pathways to vulnerability and to implement interventions shown to be effective in remediating risks and improving outcomes for this population are indicated. Evaluation of efficacious interventions in countries outside of the United States is also needed.

Abstract
Research employing electroencephalographic (EEG) techniques with infants and young children has flourished in recent years due to increased interest in understanding the neural processes involved in early social and cognitive development. This review focuses on the functional characteristics of the alpha, theta, and gamma frequency bands in the developing EEG. Examples of how analyses of EEG band power have been applied to specific lines of developmental research are also discussed. These examples include recent work on the infant mu rhythm and action processing, frontal alpha asymmetry and approach-withdrawal tendencies, and EEG power measures in the study of early psychosocial adversity.

Abstract
This paper describes the Multidimensional Treatment Foster Care program (MTFC), an evidence based approach for providing psychotherapeutic treatment for very troubled children and adolescents that is an alternative to residential care. Versions of the MTFC program have been developed and validated for young children with a history of maltreatment as well as for older children and adolescents who are involved with the youth justice system. In the paper we describe the development of the MTFC program and its foundations in the social learning model that originated at the Oregon Social Learning Center in the 1960's and 70's. We present information about program elements. We then review the research that has been conducted on MTFC.

Abstract
Prior researchers have shown that the brain has a remarkable ability for adapting to environmental changes. The positive effects of such neural plasticity include enhanced functioning in specific cognitive domains and shifts in cortical representation following naturally occurring cases of sensory deprivation; however, maladaptive changes in brain function and development owing to early developmental adversity and stress have also been well documented. Researchers examining enriched rearing environments in animals have revealed the potential for inducing positive brain plasticity effects and have helped to popularize methods for training the brain to reverse early brain deficits or to boost normal cognitive functioning. In this article, two classes of empirically based methods of brain training in children are reviewed and critiqued: laboratory-based, mental process training paradigms and ecological interventions based upon neurocognitive conceptual models. Given the susceptibility of executive function disruption, special attention is paid to training programs that emphasize executive function enhancement. In addition, a third approach to brain training, aimed at tapping into compensatory processes, is postulated. Study results showing the effectiveness of this strategy in the field of neurorehabilitation and in terms of naturally occurring compensatory processing in human aging lend credence to the potential of this approach.

Abstract
Children who spend early portions of their lives in institutions or those maltreated in their families of origin are at risk for developing emotional and behavioral problems reflecting disorders of emotion and attention regulation. Animal models may help explicate the mechanisms producing these effects. Despite the value of the animal models, many questions remain in using the animal data to guide studies of human development. In 1999, the National Institute of Mental Health in the United States funded a research network to address unresolved issues and enhance translation of basic animal early experience research to application in child research. Professor Seymour Levine was both the inspiration for and an active member of this research network until his death in October of 2007. This review pays tribute to his legacy by outlining the conceptual model which is now guiding our research studies.
