The relationship between stressful life events and the error-related negativity in children and adolescents

Childhood anhedonia symptoms and stressful life events predict the development of reward-related brain activity across adolescence

The reward positivity (RewP) is an event-related potential that indexes reinforcement learning and reward system activation. The RewP has been shown to increase across adolescence; however, most studies have examined the RewP across two assessments, and no studies have examined within-person changes across adolescence into young adulthood. Moreover, the RewP has been identified as a neurobiological risk factor for adolescent-onset depression, but it is unclear whether childhood psychosocial risk factors might predict RewP development across adolescence. In a sample of 317 8- to 14-year-old girls (Mage = 12.4, SD = 1.8), the present study examined self-report measures of depression symptoms and stressful life events at baseline and the ΔRewP during the doors guessing task across three timepoints. Growth modeling indicated that, across all participants, the ΔRewP did not demonstrate linear change across adolescence. However, baseline anhedonia symptoms predicted within-person changes in the ΔRewP, such that individuals with low anhedonia symptoms demonstrated a linear increase in the ΔRewP, but individuals with high anhedonia symptoms had no change in the ΔRewP across adolescence. Similar patterns were observed for stressful life events. The present study suggests that childhood risk factors impact the development of reward-related brain activity, which might subsequently increase risk for psychopathology.

Sex Differences in the Associations Among Parenting, Socioeconomic Status, and Error Monitoring Among Adolescents

The error-related negativity (ERN) is a frontocentral deflection in the human EEG that is sensitive to error commission. Past research indicates that the ERN is modulated by individual differences in socioeconomic status (SES) and parenting style; however, there is limited research examining sex-differences in how these factors influence the ERN. The present study aimed to elucidate the relations among SES, parenting style, sex, and the ERN. In this study, 176 participants from a relatively large longitudinal study performed a Flanker task at age 15 years to measure the ERN. At the same assessment time, parenting style was assessed via parent report using the Parenting Styles and Dimension Questionnaire (PSDQ). Parents reported on their highest level of education which was used as an indicator of household SES. Authoritarian and permissive parenting scores each significantly moderated the relation between maternal education and ERN amplitudes, but in both cases this moderation differed by child sex. There were no significant direct associations between maternal education and ERN amplitude or between parenting scores and ERN amplitude. Overall, findings may suggest sex differences in the impact of social context on error monitoring development. This study highlights (1) that parenting behaviors may modulate the impact of SES on cognitive control and and (2) the importance of considering sex differences when examining the interplay between SES, parenting, and cognitive control.

Family study of the error-related negativity in adolescent and young adult females and their parents

The error-related negativity (ERN) has been identified as a potential endophenotype of psychopathology. However, there is limited research investigating familial transmission of the ERN, particularly across developmental phases that are associated with increased risk for psychopathology. The present study included a sample of one hundred thirty-one adolescent and young adult females (Mage = 17.77, SD = 1.84) and their biological parents at a first assessment and 75 females (Mage = 20.48, SD = 1.75) and their biological parents at a second assessment. Participants and their parents completed a flanker task while electroencephalography was recorded to examine parent-daughter associations of the ERN, correct response negativity (CRN), and ΔERN (i.e., ERN-CRN) at two assessments that were separated by approximately 3 years (Myears = 2.84, SD = 0.60). The daughters also completed self-report measures of generalized anxiety and depression symptoms. Results indicated that the ΔERN, but not the ERN or CRN, was positively correlated between parents and their daughters at both assessments. Furthermore, the parent-daughter correlation strength did not differ between assessments. Finally, both daughter and parent ∆ERNs were associated with daughter generalized anxiety and depression symptoms. The present study suggests that, like psychiatric disorders, the ERN runs in families and is associated with both concurrent and familial psychopathology, supporting its conceptualization as an endophenotype of psychopathology.

No association between error-related ERPs and trait anxiety in a nonclinical sample: Convergence across analytical methods including mass-univariate statistics

Enhanced error monitoring, as indexed by increased amplitude of the error-related negativity (ERN) event-related potential (ERP) component, has been suggested to reflect a vulnerability neuro-marker of anxiety disorders. Another error-related ERP component is the error positivity (Pe), which reflects late-stage error processing. The associations between heightened ERN and Pe amplitudes and anxiety levels in the nonclinical population have been inconsistent. In this preregistered study, we examined the association between anxiety, ERN, and Pe, using different analytical methods (mass-univariate analyses, MUAs and conventional analyses), self-reported anxiety scales (STAI and STICSA), and trial numbers (all correct trials and equal numbers of correct and error trials). In a sample of 82 healthy adults, both conventional and MUAs demonstrated a robust enhancement of the ERN and Pe to errors relative to the correct-response ERPs. However, the mass-univariate approach additionally unveiled a wider array of electrodes and a longer effect duration for this error enhancement. Across the analytic methods, the results showed a lack of consistent correlation between trait anxiety and error-related ERPs. Findings were not modulated by trial numbers, analyses, or anxiety scales. The present results suggest a lack of enhancement of error monitoring by anxious traits in individuals with subclinical anxiety and those with clinical anxiety but without a clinical diagnosis. Importantly, the absence of such correlation questions the validity of the ERN as a neural marker for anxiety disorders. Future studies that investigate neuro-markers of anxiety may explore alternative task designs and employ robust statistics to provide a more comprehensive understanding of anxiety vulnerability.

Adversity and error-monitoring: Effects of emotional context

This study tested whether self-reports of childhood adversity would predict altered error processing under emotional versus non-emotional task conditions. N = 99 undergraduates completed two selective attention tasks, a traditional color-word Stroop task and a modified task using emotional words, while EEG was recorded. Participants also completed self-report measures of adverse and positive childhood experiences, executive functioning, depression, current stress, and emotion regulation. Reports of adversity were robustly correlated with self-reported challenges in executive functioning, even when controlling for self-reported depression and stress, but adversity was not correlated with task performance. With regard to neural markers of error processing, adversity predicted an enhanced error-related negativity and blunted error-positivity, but only during the emotion-word blocks of the task. Moreover, error-related changes in alpha oscillations were predicted by adversity, in a pattern that suggested less error responsiveness in alpha patterns during the emotion block, compared to the color block, among participants with higher adversity. Overall, results indicate alterations in error monitoring associated with adversity, such that in an emotional context, initial error detection is enhanced and sustained error processing is blunted, even in the absence of overt performance changes.

A network analysis of affective and motivational individual differences and error monitoring in a non-clinical sample

Error monitoring, which plays a crucial role in shaping adaptive behavior, is influenced by a complex interplay of affective and motivational factors. Understanding these associations often proves challenging due to the intricate nature of these variables. With the aim of addressing previous inconsistencies and methodological gaps, in this study, we utilized network analysis to investigate the relationship between affective and motivational individual differences and error monitoring. We employed six Gaussian Graphical Models on a non-clinical population ($N$ = 236) to examine the conditional dependence between the amplitude of response-related potentials (error-related negativity; correct-related negativity) and 29 self-report measures related to anxiety, depression, obsessive thoughts, compulsive behavior, and motivation while adjusting for covariates: age, handedness, and latency of error-related negativity and correct-related negativity. We then validated our results on an independent sample of 107 participants. Our findings revealed unique associations between error-related negativity amplitudes and specific traits. Notably, more pronounced error-related negativity amplitudes were associated with increased rumination and obsessing, and decreased reward sensitivity. Importantly, in our non-clinical sample, error-related negativity was not directly associated with trait anxiety. These results underscore the nuanced effects of affective and motivational traits on error processing in healthy population.

Induced error-related theta activity, not error-related negativity, predicts task performance as well as anxiety and worry during real-life stress in a youth sample

OBJECTIVE

The study examined differences between induced error-related theta activity (4-7 Hz) and error-related negativity (ERN) in youth and their unique associations with task performance as well as anxiety and worry during real-life stress a year later. We hypothesized that induced theta, but not the ERN, would predict task performance. We also hypothesized that induced theta would predict less anxiety and worries during situational stress a year later, while ERN would predict more anxiety and worries.

METHOD

Participants included 76 children aged 8-13 years who completed a flanker task while electroencephalogram (EEG) and behavioral data (t0 ) were collected. Approximately 1 year later (t1 ), during the first COVID-19 lockdown, 40 families from the original sample completed a battery of online questionnaires to assess the children's stress-related symptoms (anxiety, negative emotions and worries). We employed an analytical method that allowed us to differentiate between induced error-related theta and the evoked ERN.

RESULTS

Induced error-related theta, but not ERN, was associated with behavioral changes during the task, such as post-error speeding. Furthermore, induced error-related theta, but not ERN, was prospectively associated with less anxiety, worries, and fewer negative emotions a year later during COVID-19 lockdown.

CONCLUSIONS

Findings suggest ERN and error-related theta are dissociable processes reflecting error monitoring in youth. Specifically, induced error-related theta is more robustly associated with changes in behavior in the laboratory and with less anxiety and worries in real-world settings.

The associations among sleep-related difficulties, anxiety, and error-related brain activity in youth

Given the high prevalence of anxiety disorders and their associated impairment, elucidating neural mechanisms related to these disorders has been increasingly prioritized. The error-related negativity (ERN) has been identified as a neural marker that indexes risk for anxiety across development. The ERN seems to confer risk for developing anxiety, especially in the context of stressful life events. The present study sought to examine sleep-related difficulties as another stressful factor that might impact the ERN. In a sample of 221 girls, aged 8 to 15 years old, we first examined the relationship between longer-term (i.e., over the past month) and shorter-term (i.e., over the past week) sleep difficulties and the ERN. We then investigated whether specific sleep difficulties uniquely predict the ERN. In exploratory analyses, we assessed whether sleep difficulties moderate the relationship between the ERN and anxiety. Results indicated that youth who report longer-term lower sleep duration, longer-term worse sleep, and shorter-term lower sleep duration on school days over the past week have a larger (i.e., more negative) ERN. Additionally, only shorter-term sleep duration on school days over the past week uniquely predicted the ERN. Finally, an elevated ERN predicted greater clinical anxiety in the context of longer-term sleep difficulties. Future studies should clarify the direction of these associations via longitudinal designs.

Childhood Adversity and Youth Suicide Risk: The Mediating Role of Intolerance of Uncertainty

Exposure to adverse childhood experiences (ACEs) is a well-established risk factor for suicidality in adolescence and young adulthood. However, the specific mechanisms underlying this relationship remain unclear. Existing research and theoretical frameworks suggest alterations in cognitive and affective processes may account for this association. Intolerance of uncertainty (IU) exacerbates negative affect and arousal states and may contribute to sustained distress. It is therefore plausible that ACEs may be associated with high IU, and in turn, high IU may be associated with increased suicide risk. The present study directly tests this hypothesis in a cohort of youth (18-19 years) with varying ACE exposure. Participants with and without a history of trauma (N=107) completed a battery of self-report questionnaires to assess ACEs, IU, and suicide risk. Results revealed ACEs were significantly associated with both IU and suicide risk. IU and suicide risk were also correlated. Importantly, findings demonstrated a significant indirect effect of ACEs on suicide risk through IU. Findings converge with broader literature on the relationship between childhood adversity and suicidality and extend previous research by highlighting IU as a mediator of this relationship, positing IU as a potentially viable target for suicide prevention among those with a history of ACEs.

The relation between executive functions, error-related brain activity, and ADHD symptoms in clinically evaluated school-aged children

Two event-related potentials (ERPs) elicited following errors, the error-related negativity (ERN) and error positivity (Pe), have been proposed to reflect cognitive control, though the specific processes remain debated. Few studies have examined the ERN and Pe's relations with individual differences in cognitive control/executive functioning using well-validated tests administered separately from the inhibition tasks used to elicit the ERN/Pe. Additionally, neurocognitive tests of executive functions tend to strongly predict ADHD symptoms, but the extent to which task-based and EEG-based estimates of executive functioning/cognitive control account for the same variance in ADHD symptoms remains unclear. The current study addressed these limitations by examining relations between the ERN/Pe and three core executive functions (working memory, inhibitory control, set shifting) in a clinically-evaluated sample of 53 children ages 8-12 (Mage = 10.36, SD = 1.42; 77.4% White/Non-Hispanic; 16 girls) with and without ADHD. Results demonstrated that neither the ERN nor Pe were related to overall cognitive control/executive functioning, or to working memory or set shifting specifically (all 95%CIs include 0.0). In contrast, a larger Pe was associated with better-developed inhibitory control (β=-.35, 95%CI excludes 0.0), but did not capture aspects of inhibitory control that are important for predicting ADHD symptoms. Neither the ERN nor Pe predicted ADHD symptoms (95%CIs include 0.0). Results were generally robust to control for age, sex, SES, ADHD symptom cluster, and anxiety, and emphasize the need for caution when interpreting the ERN/Pe as indices of broad-based cognitive control/executive functioning, as well as using the ERN/Pe to examine cognitive processes contributing to ADHD symptomatology.

Multimodal study of the neural sources of error monitoring in adolescents and adults

The ability to monitor performance during a goal-directed behavior differs among children and adults in ways that can be measured with several tasks and techniques. As well, recent work has shown that individual differences in error monitoring moderate temperamental risk for anxiety and that this moderation changes with age. We investigated age differences in neural responses linked to performance monitoring using a multimodal approach. The approach combined functional MRI and source localization of event-related potentials (ERPs) in 12-year-old, 15-year-old, and adult participants. Neural generators of two components related to performance and error monitoring, the N2 and ERN, lay within specific areas of fMRI clusters. Whereas correlates of the N2 component appeared similar across age groups, age-related differences manifested in the location of the generators of the ERN component. The dorsal anterior cingulate cortex (dACC) was the predominant source location for the 12-year-old group; this area manifested posteriorly for the 15-year-old and adult groups. A fMRI-based ROI analysis confirmed this pattern of activity. These results suggest that changes in the underlying neural mechanisms are related to developmental changes in performance monitoring.

Relational victimization prospectively predicts increases in error-related brain activity and social anxiety in children and adolescents across two years

Recent research has focused on identifying neural markers associated with risk for anxiety, including the error-related negativity (ERN). An elevated ERN amplitude has been observed in anxious individuals from middle childhood onward and has been shown to predict risk for future increases in anxiety development. The ERN is sensitive to environmental influences during development, including interpersonal stressors. Of note, one particular type of interpersonal stressor, relational victimization, has been related to increases in anxiety in adolescents. We tested whether relational victimization predicts increases in the ERN and social anxiety symptoms across two years in a sample of 152 child and adolescent females (ages 8 - 15). Results indicated that children and adolescents' baseline ERN was positively related to the ERN two years later. Furthermore, greater relational victimization at baseline predicted greater increases in the ERN two years later, controlling for baseline ERN. Moreover, relational victimization at baseline predicted increases in social anxiety, and this relationship was mediated by increases in the ERN. These results suggest that relational victimization impacts the developmental trajectory of the neural response to errors and thereby impacts increases in social anxiety among children and adolescents.

Childhood trauma predicts blunted error monitoring in adulthood: An event-related potential study

Abuse and neglect have detrimental consequences on emotional and cognitive functioning during childhood and adolescence, including error monitoring, which is a critical aspect of cognition that has been implicated in certain internalizing and externalizing psychopathologies. It is unclear, however, whether (a) childhood trauma has effects on error monitoring and, furthermore whether, (b) error monitoring mediates the relation between childhood trauma and psychopathology in adulthood. To this end, in a large sample of young adults (ages 18-30) who were oversampled for psychopathology (N = 390), the present study assessed relations between childhood trauma and error-related negativity (ERN), which is a widely used neurophysiological indicator of error monitoring. Cumulative childhood trauma predicted ERN blunting, as did two specific types of traumas: sexual abuse and emotional neglect. Furthermore, the ERN partially mediated the effects of cumulative childhood trauma and emotional neglect on externalizing-related symptoms. Future studies should further examine the relations between childhood trauma and error monitoring in adulthood, which can help to inform intervention approaches.

Performance monitoring moderates the relationship between stress and negative affect in response to an exam stressor

The present longitudinal study examined the role of performance monitoring in the relationships between stress (both stress change and chronic stress) and negative affect to a real-life stressor-final exam among 60 undergraduates. Participants firstly completed a Go/No-Go task in the laboratory with electroencephalogram recordings. At T1 (31 days before the final exam), participants reported their chronic perceived stress. Then, with the daily dairy method, their daily stress level and negative affect were collected for three consecutive days. At T2 (three days before the final exam), the 3-day daily dairy was repeated. Results showed that performance monitoring, as measured by behavioral adjustments and electrophysiological correlates, moderated the effects of stress change as well as chronic perceived stress on the negative emotional response to the final exam. More specifically, as the stress change from baseline to exam increases, individuals with shorter PES, lower PEAD or larger Pe amplitudes experienced less negative affect increases in response to exam. Additionally, individuals with shorter PES or larger Pe amplitudes showed no significant relationship between chronic stress and negative affect, whereas individuals with longer PES or smaller Pe amplitudes showed significant positive relationship between chronic stress and negative affect increases in response to exam. The results demonstrated that efficient performance monitoring is a protective factor for stress.

Life Events in the Etiopathogenesis and Maintenance of Restrictive Eating Disorders in Adolescence

Life events (traumatic and protective) may be critical factors associated with eating disorders and their severity. To date, there is little literature concerning the role of life events in adolescence. The main goal of this study was to explore in a sample of adolescent patients with restrictive eating disorders (REDs) the presence of life events in the year before enrolment and to characterize them according to timing. Furthermore, we investigated correlations between REDs severity and the presence of life events. In total, 33 adolescents completed the EDI-3 questionnaire to assess RED severity using EDRC (Eating Disorder Risk Composite), GPMC (General Psychological Maladjustment Composite), and the Coddington Life Events Scales-Adolescent (CLES-A) questionnaires to define the presence of life events in the last year. Of these, 87.88% reported a life event in the past year. A significant association emerged between elevated clinical GPMC and the presence of traumatic events: patients who had experienced at least one traumatic life event in the year before enrolment presented higher clinically elevated GPMC compared to patients who had not. These results suggest that obtaining early information about traumatic events in clinical practice may help prevent the occurrence of new events and improve patient outcomes.

Corporal Punishment Is Uniquely Associated With a Greater Neural Response to Errors and Blunted Neural Response to Rewards in Adolescence

BACKGROUND

Although corporal punishment is a common form of punishment with known negative impacts on health and behavior, how such punishment affects neurocognitive systems is relatively unknown.

METHODS

To address this issue, we examined how corporal punishment affected neural measures of error and reward processing in 149 adolescent boys and girls of ages 11 to 14 years (mean age [SD] = 11.02 [1.16]). Corporal punishment experienced over the lifetime was assessed using the Stress and Adversity Inventory. In addition, participants completed a flankers task and a reward task to measure the error-related negativity and reward positivity, respectively, as well as measures of anxiety and depressive symptoms.

RESULTS

As hypothesized, participants who experienced lifetime corporal punishment reported more anxiety and depressive symptoms. Experiencing corporal punishment was also related to a larger error-related negativity and blunted reward positivity. Importantly, corporal punishment was independently related to a larger error-related negativity and a more blunted reward positivity beyond the impact of harsh parenting and lifetime stressors.

CONCLUSIONS

Corporal punishment appears to potentiate neural response to errors and decrease neural response to rewards, which could increase risk for anxiety and depressive symptoms.

Type of Trauma Exposure Impacts Neural Reactivity to Errors

Abstract. Studies suggest that individuals with a history of trauma exposure display abnormal reactivity to threat, though the pattern of findings across prior studies has been inconsistent. At least two factors likely contribute to previous discrepant findings: (1) the type of index trauma event and (2) the type of threat paradigm. Accordingly, the current study aimed to examine the impact of trauma type on a specific psychophysiological index of threat sensitivity – error negativity (Ne), also described as error-related negativity (ERN). Young adults were classified into three groups: lifetime history of interpersonal trauma (i.e., sexual assault, physical assault, or immediate family violence; n = 30), lifetime history of a non-interpersonal trauma (e.g., accidents, natural disasters; n = 30), or no lifetime history of trauma ( n = 64). All participants completed a well-validated flanker task designed to elicit the Ne/ERN during continuous electroencephalographic (EEG) data collection. Results indicated that individuals with non-interpersonal trauma exposure displayed reduced Ne/ERN amplitude compared with the other two groups (who did not differ from each other). Broadly, these findings highlight the importance of trauma type and theory suggesting different forms of trauma may result in different neurobiological profiles. These findings also add to a growing literature indicating that non-interpersonal traumas may be uniquely associated with blunted threat sensitivity and deficiencies in self-monitoring.

The impact of punishment on error-related brain activity in children

The error-related negativity (ERN) is sensitive to individual differences relating to anxiety and is modulated by manipulations that increase the threat-value of committing errors. In adults, the ERN magnitude is enhanced when errors are followed by punishment, especially among anxious individuals. Punitive parenting is related to an elevated ERN in children; however, the effects of task-based punishment on the ERN in children have yet to be understood. Furthermore, there is a need to assess developmental periods wherein the ERN might be especially prone to modulation by punishment. We examined the impact of punishment on the ERN in a sample of children and assessed whether the impact of punishment on the ERN was moderated by age and anxiety. Punishment potentiated the ERN in children, especially among higher trait-anxious individuals; the punishment potentiation of the ERN was also associated with older age. The interaction between child age and anxiety symptoms did not significantly predict the punishment potentiation of the ERN; however, both child age and anxiety symptoms uniquely predicted the punishment potentiation of the ∆ERN. Anxious children may be especially prone to punishment-related alterations in error monitoring, and the impact of punishment on the ERN may become more pronounced as children age.

The Relationship Between Negative Life Events and Nonsuicidal Self-Injury Among Chinese Adolescents: A Moderated-Mediation Model

OBJECTIVE

This study aimed to investigate whether anxiety mediates the relationship between negative life events and nonsuicidal self-injury (NSSI) in adolescents and whether this mediating role is moderated through social support.

METHODS

The model consisted of an anonymous questionnaire survey of 506 Chinese adolescents (253 boys and 253 girls, mean age 15.11 years (SD = 1.83, range 11-18 years)). Self-designed questionnaires were used to collect demographic data. The frequency of NSSI, state anxiety, and social support degree of adolescents was assessed by the Adolescent Life Events Scale, the Chinese version of the Beck Anxiety Inventory, and the social support scale, respectively.

RESULTS

Negative life events were significantly and positively correlated with anxiety and the frequency of NSSI, and anxiety was significantly and positively correlated with the frequency of NSSI. The positive association between negative life events and the frequency of NSSI among adolescents was mediated by anxiety after controlling for demographic variables. Furthermore, this mediated relationship was moderated by social support.

CONCLUSION

Anxiety was a potential mechanism linking negative life events to NSSI in adolescents and low social support important risk factor for amplifying this indirect effect. Our findings provide an empirical basis for reducing NSSI in adolescents.
