Neurodevelopmental changes across adolescence in viewing and labeling dynamic peer emotions

Probing Puberty as a Source of Developmental Change in Neural Response to Emotional Faces in Early Adolescence

Pubertal development is theorized to shape the brain's response to socio-emotional information in the environment. Large-scale longitudinal studies, such as the Adolescent Brain Cognitive Development (ABCD) study, provide the opportunity to examine the association between pubertal maturation and within-person changes in neural activation to emotional stimuli over time. Leveraging ABCD data (n = 9648), the current study examines the coupling between parent-reported pubertal development and changes in youth's brain response to emotional faces in an emotional n-back task (during functional magnetic resonance imaging) across two timepoints (2 years apart). Bivariate latent change score models were fit to regions of interest canonically involved in face processing (fusiform), emotional/motivational salience (amygdala, nucleus accumbens, orbitofrontal cortex [OFC]), and social cognition (temporoparietal junction [TPJ]) to determine the associations between baseline pubertal status and neural response, and rate of change in either variable across time. Results point to both concurrent and longitudinal associations between pubertal maturation and neural activation to emotional faces in regions involved in processing emotional and social information (amygdala, TPJ, accumbens, OFC) but not basic facial processing (fusiform). These findings highlight pubertal maturation as a potential mechanism for change in neural response to emotional information during the transition from childhood to adolescence.

Stress Reduction in Perioperative Care: Feasibility Randomized Controlled Trial

BACKGROUND

Patients undergoing surgery often experience stress and anxiety, which can increase complications and hinder recovery. Effective management of these psychological factors is key to improving outcomes. Preoperative anxiety is inversely correlated with the amount of information patients receive, but accessible, personalized support remains limited, especially in preoperative settings. Face-to-face education is often impractical due to resource constraints. Digital health (DH) interventions offer a promising alternative, enhancing patient engagement and empowerment. However, most current tools focus on providing information, overlooking the importance of personalization and psychological support.

OBJECTIVE

This study aimed to assess the viability of a DH intervention known as the Adhera CARINAE DH Program. This program is specifically designed to offer evidence-based and personalized stress- and anxiety-management techniques. It achieves this by using a comprehensive digital ecosystem that incorporates wearable devices, mobile apps, and virtual reality technologies. The intervention program also makes use of advanced data-driven techniques to deliver tailored patient education and lifestyle support.

METHODS

A total of 74 patients scheduled for surgery across 4 hospitals in 3 European countries were enrolled in this study from September 2021 to March 2022. Surgeries included cardiopulmonary and coronary artery bypass surgeries, cardiac valve replacements, prostate or bladder cancer surgeries, hip and knee replacements, maxillofacial surgery, and scoliosis procedures. After assessment for eligibility, participants were randomized into 2 groups: the intervention group (n=23) received the Adhera CARINAE DH intervention in addition to standard care, while the control group (n=27) received standard care alone. Psychological metrics such as self-efficacy, self-management, and mental well-being were assessed before and after the intervention, alongside physiological markers of stress.

RESULTS

The intervention group demonstrated significant improvements across several psychological outcomes. For example, Visual Analogue Scale Stress at the hospital improved at admission by 5% and at hospital discharge by 11.1% and Visual Analogue Scale Pain at admission improved by 31.2%. In addition, Hospital Anxiety and Depression Scale Anxiety after surgery improved by 15.6%, and Positive and Negative Affect Scale-Negative at hospital admission improved by 17.5%. Overall, patients in the intervention study spent 17.12% less days in the hospital. Besides these individual scores, the intervention group shows more positive relationships among the psychological dimensions of self-efficacy, self-management, and mental well-being, suggesting that the CARINAE solution could have a positive effect and impact on the reduction of stress and negative emotions.

CONCLUSIONS

Our results provide an important first step toward a deeper understanding of optimizing DH solutions to support patients undergoing surgery and for potential applications in remote patient monitoring and communication.

Associations Between Parenting Behavior and Neural Processing of Adolescent Faces in Mothers With and Without Depression

BACKGROUND

This study first examined how mothers with and without depression differ in neural activation in response to adolescents' affective faces. Second, it examined the extent to which these neural activation patterns are related to observed positive and aggressive parenting behavior.

METHODS

Mothers with and without depression (based on self-reported symptoms and treatment history; n = 77 and n = 64, respectively; meanage = 40 years) from low-income families completed an interaction task with their adolescents (meanage = 12.8 years), which was coded for parents' aggressive and positive affective behavior. During functional magnetic resonance imaging, mothers viewed blurry, happy, sad, and angry faces of unfamiliar adolescents, with an instruction to either label the emotion or determine the clarity of the image.

RESULTS

The depression group showed less activation in the posterior midcingulate than the control subject group while labeling happy faces. Higher activation in the insula and dorsomedial prefrontal cortex (PFC) was related to less positive parenting behavior. Ventrolateral PFC activation was most pronounced when labeling negative emotions, but stronger ventrolateral PFC response to happy faces was associated with more aggressive parenting behavior.

CONCLUSIONS

This demonstrates the association between parents' neural responses to adolescent faces and their behavior during interactions with their own adolescents, with relatively low insula and dorsomedial PFC activation supporting positive parenting and affect-dependent response in the ventrolateral PFC as being important to limit aggressive behavior.

Pregnancy in autistic women and social medical considerations: scoping review and meta- synthesis

Introduction

This article addresses a topic that has been largely overlooked by scientific literature, namely pregnancy in autistic women. Generally, the issue of sexuality in disability, particularly in disabled women, autistic or otherwise, has been underexplored. However, it is necessary to scientifically investigate this topic to propose adequate social and health policies. Therefore, we chose to conduct a scoping review to answer three main questions: "What does it mean for an autistic woman to be pregnant?"; "How do these two conditions coexist?"; "Are health services prepared to receive this population adequately or does autism become a stigma for pregnant women?"

Methods

We conducted a systematic review and qualitative thematic synthesis following the Preferred Reporting Guidelines for Systematic Reviews and Meta-Analyses on autistic women and pregnancy in the last 10 years.

Results

The studies included in our review are 7, extremely diverse in terms of methodologies and sample sizes. Despite the heterogeneity of samples and methodologies, all research tends to highlight the following results. For autistic women during pregnancy, three areas seem to be the most difficult: sensory issues, mood disorders, and relationships with specialists.

Discussion

Our study found that women with ASD face unique challenges during childbirth that differ from those of neurotypical women. Participants often felt belittled, ignored, and uninformed about the care they received, and being placed at the centre of attention was often seen as negative and hindering rather than positive. However, the research shows us how some "expected" results, such as difficulties in breastfeeding, have been disproven.

Timing of Violence Exposure and Girls' Temperament Stability From Childhood to Adolescence

Individual differences in temperament (e.g., negative emotionality) are robust early predictors of emotional and behavioral health. Although temperament is often conceptualized as relatively stable across the lifespan, evidence suggests that it may change over time as a function of social context. Extant studies have been limited by cross-sectional or short-term longitudinal designs that have precluded tests of stability as well as factors that may influence stability across developmental periods. In addition, few studies have tested the impact of social contexts that are common for children living in urban and under-resourced environments, such as exposure to community violence. In the present study we hypothesized that levels of negative emotionality, activity, and shyness would decrease across development from childhood to mid-adolescence as a function of early exposure to violence in the Pittsburgh Girls Study, a community study of girls enriched for families living in low-resourced neighborhoods. Temperament was assessed by parent- and teacher-report on the Emotionality Activity Sociability Shyness Temperament Survey in childhood (5-8-years-old), early-adolescence (11-years-old), and mid-adolescence (15-years-old). Violence exposure (e.g., victim of or witness to violent crime, exposure to domestic violence) was assessed annually via child and parent report. Results showed that on average, combined caregiver and teacher reports of negative emotionality and activity level exhibited small but significant reductions from childhood to adolescence, whereas shyness remained stable. Violence exposure in early adolescence predicted increases in negative emotionality and shyness by mid-adolescence. Violence exposure was not associated with stability of activity level. Our findings suggest that exposure to violence, particularly in early adolescence, amplifies individual differences in shyness and negative emotionality, underlying an important pathway of risk for developmental psychopathology.

Adolescents and young adults differ in their neural response to and recognition of adolescent and adult emotional faces

Peer relationships become increasingly important during adolescence. The success of these relationships may rely on the ability to attend to and decode subtle or ambiguous emotional expressions that are common in social interactions. However, most studies examining youths' processing and labeling of facial emotion have employed adult faces and faces that depict emotional extremes as stimuli. In this study, 40 adolescents and 40 young adults viewed blends of angry-neutral, fearful-neutral, and happy-neutral faces (e.g., 100% angry, 66% angry, 33% angry, neutral) portrayed by adolescent and adult actors as electroencephalogram (EEG) was recorded. Participants also labeled these faces according to the emotion expressed (i.e., angry, fearful, happy, or neutral). The Late Positive Potential (LPP), an event-related potential (ERP) component that reflects sustained attention to motivationally salient information, was scored from the EEG following face presentation. Among adolescents, as peer-age faces moved from ambiguous (33%) to unambiguous (100%) emotional expression, the LPP similarly increased. These effects were not found when adolescents viewed emotional face blends portrayed by adult actors. Additionally, while both adolescents and young adults showed greater emotion labeling accuracy as faces increased in emotional intensity from ambiguous to unambiguous emotional expression, adolescent participants did not show greater accuracy when labeling peer-compared to adult-age faces. Together, these data suggest that adolescents attend more to subtle differences in peer-age emotional faces, but they do not label these emotional expressions more accurately than adults.

Revisiting the Neural Architecture of Adolescent Decision-Making: Univariate and Multivariate Evidence for System-Based Models

Understanding adolescent decision-making is significant for informing basic models of neurodevelopment as well as for the domains of public health and criminal justice. System-based theories posit that adolescent decision-making is guided by activity related to reward and control processes. While successful at explaining behavior, system-based theories have received inconsistent support at the neural level, perhaps because of methodological limitations. Here, we used two complementary approaches to overcome said limitations and rigorously evaluate system-based models. Using decision-level modeling of fMRI data from a risk-taking task in a sample of 2000+ decisions across 51 human adolescents (25 females, mean age = 15.00 years), we find support for system-based theories of decision-making. Neural activity in lateral PFC and a multivariate pattern of cognitive control both predicted a reduced likelihood of risk-taking, whereas increased activity in the NAcc predicted a greater likelihood of risk-taking. Interactions between decision-level brain activity and age were not observed. These results garner support for system-based accounts of adolescent decision-making behavior.SIGNIFICANCE STATEMENT Adolescent decision-making behavior is of great import for basic science, and carries equally consequential implications for public health and criminal justice. While dominant psychological theories seeking to explain adolescent decision-making have found empirical support, their neuroscientific implementations have received inconsistent support. This may be partly because of statistical approaches used by prior neuroimaging studies of system-based theories. We used brain modeling, an approach that predicts behavior from brain activity, of univariate and multivariate neural activity metrics to better understand how neural components of psychological systems guide decision behavior in adolescents. We found broad support for system-based theories such that neural systems involved in cognitive control predicted a reduced likelihood to make risky decisions, whereas value-based systems predicted greater risk-taking propensity.

Improving practices and inferences in developmental cognitive neuroscience

The past decade has seen growing concern about research practices in cognitive neuroscience, and psychology more broadly, that shake our confidence in many inferences in these fields. We consider how these issues affect developmental cognitive neuroscience, with the goal of progressing our field to support strong and defensible inferences from our neurobiological data. This manuscript focuses on the importance of distinguishing between confirmatory versus exploratory data analysis approaches in developmental cognitive neuroscience. Regarding confirmatory research, we discuss problems with analytic flexibility, appropriately instantiating hypotheses, and controlling the error rate given how we threshold data and correct for multiple comparisons. To counterbalance these concerns with confirmatory analyses, we present two complementary strategies. First, we discuss the advantages of working within an exploratory analysis framework, including estimating and reporting effect sizes, using parcellations, and conducting specification curve analyses. Second, we summarize defensible approaches for null hypothesis significance testing in confirmatory analyses, focusing on transparent and reproducible practices in our field. Specific recommendations are given, and templates, scripts, or other resources are hyperlinked, whenever possible.

Maternal Antecedents to Adolescent Girls' Neural Regulation of Emotion

The purpose of this study was to investigate contributions of maternal emotional resources to individual differences in adolescents' functional connectivity during emotion regulation. Participants included 35 adolescent girls who completed an implicit emotion regulation task during fMRI. Mothers reported on the quality of their adult attachment and emotional awareness when youth were in elementary school. Higher anxious attachment and lower emotional awareness were significantly correlated with more positive amygdala-right ventrolateral prefrontal cortex connectivity, a pattern linked in prior research with ineffective emotion regulation and emotional difficulties. Further, there was an indirect effect of anxious attachment on adolescent connectivity through emotional awareness. These results suggest that compromised maternal emotional resources in childhood may be linked to atypical neural processing of emotions.

Levers and barriers to success in the use of translational neuroscience for the prevention and treatment of mental health and promotion of well-being across the lifespan

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).

Affective reactivity during adolescence: Associations with age, puberty and testosterone

Adolescence is a period of heightened social engagement that is accompanied by normative changes in neural reactivity to affective stimuli. It is also a period of concurrent endocrine and physical changes associated with puberty. A growing body of research suggests that hormonal shifts during adolescence impact brain development, but minimal research in humans has examined the relationship between intra-individual changes in puberty and brain function. The current study examines linear and nonlinear changes in affective reactivity in a longitudinal sample of 82 adolescents who underwent three fMRI sessions between the ages of 9 and 18 years. Changes in response to affective facial stimuli were related to age, pubertal stage, and testosterone levels. Using multilevel modeling, we highlight extensive nonlinear development of socio-emotional responsivity across the brain. Results include mid-pubertal peaks in amygdala and hippocampus response to fearful expressions, as well as sex differences in regions subserving social and self-evaluative processes. However, testosterone levels exhibited inverse patterns of association with neural response compared to pubertal stage in females (e.g., U-shaped relationship with the amygdala and hippocampus). Findings highlight potentially unique roles of age, pubertal stage and testosterone on socio-emotional development during adolescence, as well as sex differences in these associations.

Is adolescence the missing developmental link in Microbiome-Gut-Brain axis communication?

Gut microbial research has recently opened new frontiers in neuroscience and potentiated novel therapies for mental health problems (Mayer, et al., 2014). Much of our understanding of the gut microbiome's role in brain function and behavior, however, has been largely derived from research on nonhuman animals. Even less is known about how the development of the gut microbiome influences critical periods of neural and behavioral development, particularly adolescence. In this review, we first discuss why the gut microbiome has become increasingly relevant to developmental cognitive neuroscience and provide a synopsis of the known connections of the gut microbiome with social-affective brain function and behavior, specifically highlighting human developmental work when possible. We then focus on adolescence, a key period of neurobiological and social-affective development. Specifically, we review the links between the gut microbiome and six overarching domains of change during adolescence: (a) social processes, (b) motivation and behavior, (c) neural development, (d) cognition, (e) neuroendocrine function, and (f) physical health and wellness. Using a developmental science perspective, we summarize key changes across these six domains to underscore the promise for the gut microbiome to bidirectionally influence and transform adolescent development.

Moderate social sensitivity in a risky context supports adaptive decision making in adolescence: evidence from brain and behavior

Adolescence is a time of increased social-affective sensitivity, which is often related to heightened health-risk behaviors. However, moderate levels of social sensitivity, relative to either low (social vacuum) or high levels (exceptionally attuned), may confer benefits as it facilitates effective navigation of the social world. The present fMRI study tested a curvilinear relationship between social sensitivity and adaptive decision-making. Participants (ages 12-16; N = 35) played the Social Analogue Risk Task, which measures participants' willingness to knock on doors in order to earn points. With each knock, the facial expression of the house's resident shifted from happy to somewhat angrier. If the resident became too angry, the door slammed and participants lost points. Social sensitivity was defined as the extent to which adolescents adjusted their risky choices based on shifting facial expressions. Results confirmed a curvilinear relationship between social sensitivity and self-reported adaptive decision-making at the behavioral and neural level. Moderate adolescent social sensitivity was modulated via heightened tracking of social cues in the temporoparietal junction, insula and dorsolateral prefrontal cortex and related to adaptive decision-making. These findings suggest that social-affective sensitivity may positively impact outcomes in adolescence and have implications for interventions to help adolescents reach mature social goals into adulthood.

Social perspective taking is associated with self-reported prosocial behavior and regional cortical thickness across adolescence

Basic perspective taking and mentalizing abilities develop in childhood, but recent studies indicate that the use of social perspective taking to guide decisions and actions has a prolonged development that continues throughout adolescence. Here, we aimed to replicate this research and investigate the hypotheses that individual differences in social perspective taking in adolescence are associated with real-life prosocial and antisocial behavior and differences in brain structure. We used an experimental approach and a large cross-sectional sample (n = 293) of participants aged 7–26 years old to assess age-related improvement in social perspective taking usage during performance of a version of the director task. In subsamples, we then tested how individual differences in social perspective taking were related to self-reported prosocial behavior and peer relationship problems on the Strengths and Difficulties Questionnaire (n = 184) and to MRI measures of regional cortical thickness and surface area (n = 226). The pattern of results in the director task replicated previous findings by demonstrating continued improvement in use of social perspective taking across adolescence. The study also showed that better social perspective taking usage is associated with more self-reported prosocial behavior, as well as to thinner cerebral cortex in regions in the left hemisphere encompassing parts of the caudal middle frontal and precentral gyri and lateral parietal regions. These associations were observed independently of age and might partly reflect individual developmental variability. The relevance of cortical development was additionally supported by indirect effects of age on social perspective taking usage via cortical thickness.

Not just social sensitivity: Adolescent neural suppression of social feedback during risk taking

Adolescence is a period of sensitivity to social stimuli. In particular, research has focused on the increased sensitivity to risks and social information seen during adolescence. However, recent evidence also suggests that adolescents can flexibly use information in service of their goals, raising an interesting question: are adolescents able to selectively discount social information if it conflicts with their goals? To test this question, fifty-five children and adolescents (ages 8-17 years) completed a social variant of the Balloon Analogue Risk Task during an fMRI session. Adolescents showed decreased tracking of negative social feedback in regions involved in salience-monitoring (e.g. insula) and social processing (e.g., TPJ, pSTS). Age-related changes in neural processing of risk and social feedback contributed to better performance for older participants. These results suggest that adolescents are able to suppress goal-irrelevant social feedback, rather than being uniformly hyper-sensitive to social information.

Prefrontal Cortical Response to Negative Social Words Links Social Risk to Depressive Symptoms in Adolescence

Research suggests that altered emotion processing may be one important pathway linking social risk factors and depressive symptoms. We examined the extent to which neural response to negatively valenced social information might help to account for the relationship between social risk and depressive symptoms in youth. Forty-nine youth were scanned while identifying the emotional valence of words that connoted social status. They also completed questionnaires assessing self-reported social risk factors and depressive symptoms. Mediation analysis revealed that reduced dorsolateral prefrontal cortex activity in response to negative social status words explained the positive association between social risk and depressive symptoms. These findings suggest that social risk factors present during adolescence may contribute to depressive symptoms by influencing the neural substrates of emotion processing.
