Pathological personality domains and punishment-enhanced error-related negativity

The error-related negativity (ERN) is an event-related potential that is observed after the commission of an error and is hypothesized to index threat sensitivity. The ERN is associated with multiple psychiatric disorders, but it is unclear if similar results are due to higher-order dimensions of psychopathology. When errors are punished, the ERN is further enhanced, which might better isolate threat sensitivity. However, few studies have examined whether psychopathology is associated with punishment enhancement of the ERN. In a clinical sample of 170 adults, the present study examined the association between pathological personality domains and predictable vs. unpredictable punishment-enhanced ERN. Results indicated that the ERN was enhanced when errors were punished compared to not punished. Greater negative emotionality was associated with a greater predictable punishment-enhanced ERN, while greater disinhibition was associated with smaller predictable punishment-enhanced ERN. The study suggests that higher-order pathological personality domains demonstrate discriminate relationships with punishment-enhanced error-related brain activity.

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.

Performance monitoring and error detection: The role of mid frontal theta and error-related negativity (ERN) among Indian adolescents from different socioeconomic background

The aim of the study was to investigate the relationship between socioeconomic status (SES) and executive functioning, focusing specifically on performance monitoring, error detection, and their association with mid-frontal theta and error-related negativity (ERN). Employing the widely used flanker task, the research involved two phases with participants aged 10-16 years (15 individuals in the pilot phase and 35 in the second phase). Electroencephalogram (EEG) recordings from distinct brain regions were analyzed during various conditions. The study revealed a notable increase in both absolute and relative theta power at Fcz during the flanker task, with a stronger effect observed during incorrect trials. Furthermore, it underscored the influence of socioeconomic status (SES) on mid-frontal theta, highlighting interactions between SES, gender, and experimental conditions impacting both absolute and relative theta. Intriguingly, the research disclosed a positive correlation between parental occupation and error-related negativity (ERN), as well as between age and ERN. These findings underscore the significance of SES, gender, and age in shaping the neural mechanisms associated with performance monitoring and executive functions. The study contributes valuable insights into the intricate interplay between socio-demographic factors and cognitive processes, shedding light on their impact on goal-directed behaviors and brain activity.

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.

Cinematographic continuity edits across shot scales and camera angles: an ERP analysis

Film editing has attracted great theoretical and practical interest since the beginnings of cinematography. In recent times, the neural correlates of visual transitions at edit cuts have been at the focus of attention in neurocinematics. Many Event Related Potential (ERP) studies studies have reported the consequences of cuts involving narrative discontinuities, and violations of standard montage rules. However, less is known about edits that are meant to induce continuity. Here, we addressed the neural correlates of continuity editing involving scale, and angle variations across the cut within the same scene, two of the most popular devices used for continuity editing. We recorded the electroencephalographic signal obtained from 20 viewers as they watched four different cinematographic excerpts to extract ERPs at edit points. First, we were able to reproduce the general time and scalp distribution of the typical ERPs to filmic cuts in prior studies. Second, we found significant ERP modulations triggered by scale changes (scale out, scale in, or maintaining the same scale). Edits involving an increase in scale (scale out) led to amplification of the ERP deflection, and scale reduction (scale in) led to decreases, compared to edits that kept scale across the cut. These modulations coincide with the time window of the N300 and N400 components and, according to previous findings, their amplitude has been associated with the likelihood of consciously detecting the edit. Third, we did not detect similar modulations as a function of angle variations across the cut. Based on these findings, we suggest that cuts involving reduction of scale are more likely to go unnoticed, than ones that scale out. This relationship between scale in/out and visibility is documented in film edition manuals. Specifically, in order to achieve fluidity in a scene, the edition is designed from the most opened shots to the most closed ones.

An Experimental Therapeutics Approach to the Development of a Novel Computerized Treatment Targeting Error-Related Brain Activity in Young Children

In the current study, we utilize an experimental medicine approach to examine the extent to which a single-session, computerized intervention impacts a transdiagnostic neural marker of risk (i.e., the error-related negativity [ERN]) in 70 children between the ages of 6 and 9 years. The ERN is a deflection in the event-related potential occurring after an individual makes a mistake on a lab-based task and has been shown to be transdiagnostically associated with a variety of anxiety disorders (e.g., social anxiety, generalized anxiety), obsessive-compulsive disorder, and depressive disorders in over 60 studies to date. Building on these findings, work has been done to link an increased ERN to negative reactions to, and avoidance of, making mistakes (i.e., error sensitivity). In the current study, we capitalize on this previous work by examining the extent to which a single-session, computerized intervention may engage the target of "error sensitivity" (measured by the ERN, as well as self-report of error sensitivity). We examine the convergence of multiple measures of the construct of "error sensitivity" (i.e., child self-report, parent report on child, and child electroencephalogram [EEG]). We also examine relationships between these three measures of "error sensitivity" and child anxiety symptoms. Overall, results suggested that treatment condition predicted changes in self-reported error sensitivity but not changes in ERN. Based on the lack of previous work in this area, we view this study as a novel, preliminary, first step toward using an experimental medicine approach to examine our ability to engage the target of the ERN (i.e., error sensitivity) early in development.

An Experimental Therapeutics Focus on Novel Mechanistic Targets in Cognitive Behavioral Treatments: Introduction to the Special Section

This article introduces the special section, "An Experimental Therapeutics Focus on Novel Mechanistic Targets in Cognitive Behavioral Treatments." The purpose of this special section is to highlight research that follows the recommended Science of Behavior Change (SOBC) developmental progression for an experimental medicine approach to identifying and testing mechanisms of behavior change. Emphasis was placed on the earlier stage "pipeline" of investigations of novel mechanisms for behavior change: mechanisms that are undergoing the initial stages of validation. In this series, seven empirical articles are presented and are followed by an article detailing a checklist for reporting mechanistic research studies in order to improve communication of findings in the field. The final article in this series discusses the history, current status, and future directions for the SOBC approach to mechanistic science as viewed by National Institute of Health program officials.

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.

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.

Aversiveness of errors and the error-related negativity (ERN): A systematic review on the affective states' manipulations findings

Error-related negativity (ERN) has been used to investigate neural mechanisms underlying error processing and conflict monitoring. Recent evidence highlights that affective and motivational states modulate the ERN and that aversiveness of errors plays a vital role in error monitoring. Therefore, our primary objective was to systematically evaluate and describe the influence of affect state-related manipulations on the ERN. A total of 51 publications identified from PsyInfo, PubMed, and PsyArticles databases were included following the Prisma procedures for systematic reviews. Papers were analyzed using sample attributes, psychological paradigms, and states manipulations. The present study shows that the ERN component has recurrently appeared to be sensitive to manipulations of affective states in the reviewed literature. However, conclusive findings concerning the affect state-dependent properties of the ERN remain elusive. Results are discussed considering heterogeneity in paradigms, variables, and the state-trait interactions. Furthermore, recommendations for future high-quality studies are provided along with the necessity of upcoming high-power replication attempts and more studies with positive affect manipulations.

The role of attentional shifting in the relation between error monitoring and anxiety in youth

The error-related negativity (ERN), a well-established neural marker of anxiety, reflects enhanced attention to internal threat signals. While attention to threat plays a crucial role in the development and maintenance of anxiety, it is unclear how attentional control influences the ERN-anxiety association. To address this, 37 youths (M_age = 10.89 years) completed self-report measures of attentional control and anxiety symptoms. To obtain ERN amplitude, youth completed a flanker task while simultaneous EEG was collected. Attentional control, specifically attentional shifting rather than focusing, moderated the relation between ERN amplitude and anxiety. Youth who displayed smaller neural responses to making an error and higher ability to shift attention experienced lower levels of anxiety, relative to those who exhibited larger neural responses to making an error or lower attention-shifting ability. These findings highlight that response magnitude to internal threat and ability to flexibly shift attention may jointly contribute to anxiety in youth.

Associations between lifetime stress exposure and the error-related negativity (ERN) differ based on stressor characteristics and exposure timing in young adults

Life stress increases risk for multiple forms of psychopathology, in part by altering neural processes involved in performance monitoring. However, the ways in which these stress-cognition effects are influenced by the specific timing and types of life stressors experienced remains poorly understood. To address this gap, we examined how different social-psychological characteristics and developmental timing of stressors are related to the error-related negativity (ERN), a negative-going deflection in the event-related potential (ERP) waveform that is observed from 0 to 100 ms following error commission. A sample of 203 emerging adults performed an ERN-eliciting arrow flanker task and completed an interview-based measure of lifetime stress exposure. Adjusting for stress severity during other developmental periods, there was a small-to-medium effect of stress on performance monitoring, such that more severe total stress exposure, as well as more severe social-evaluative stress in particular, experienced during early adolescence significantly predicted an enhanced ERN. These results suggest that early adolescence may be a sensitive developmental period during which stress exposure may result in lasting adaptations to neural networks implicated in performance monitoring.

Targeting cognitive control to reduce anxiety in very young children: A proof of concept study

OBJECTIVE

Underdeveloped cognitive control (CC)-the capacity to flexibly adjust to changing environments-may predispose some children to early onset anxiety disorders and represents a promising intervention target. The current study established and pilot-tested "Camp Kidpower"-a novel group-based, interactive CC training intervention-and assessed its impacts on behavioral and neurophysiological indices of CC among preschool children with elevated anxiety symptoms.

METHODS

Forty-four anxious children (4-6 years) were enrolled in Camp Kidpower, delivered in four sessions over 10 days. Before and after camp, children's capacity for CC was measured using well-validated, non-trained behavioral tasks and error-related negativity (ERN). Child anxiety symptoms were measured by parent report on the Spence Preschool Anxiety Scale.

RESULTS

Thirty-two children completed the study, as defined by completion of pre- and follow-up assessments and at least three camp sessions. From baseline to after camp, performance on behavioral tests of CC improved, ERN amplitude increased, and anxiety symptoms decreased.

CONCLUSION

Results provide initial evidence that play-based cognitive training targeted to behavioral and brain markers of CC reduces anxiety in preschoolers.

Error Processing and Pain: A New Perspective

Errors put organisms in danger. Upon error commission, error processing allows for the updating of behavior that proved ineffective in light of the current context and goals, and for the activation of behavioral defensive systems. Pain, on the other hand, signals actual or potential danger to one's physical integrity and, likewise, motivates protective behavior. These parallels suggest the existence of cross-links between pain and error processing but so far their relationship remains elusive. In this review, we tie together findings from the field of pain research with those from electroencephalography studies on error processing [specifically the Error Related Negativity (ERN) and Positivity (Pe)]. More precisely, we discuss three plausible associations: Firstly, pain may enhance error processing as it increases error salience. Secondly, persons fearful of pain may be particularly vigilant towards painful errors and thus show a stronger neural response to them. Thirdly, the ERN as a component of the neural response to error commission is considered an endophenotype of threat sensitivity. As high sensitivity to pain threats is known to incite avoidance behavior, this raises the intriguing possibility that neural signatures of error processing predict pain-related protective behaviors, such as avoidance. We propose an integration of these findings into a common framework to inspire future research. Perspectives Inspired by research in anxiety disorders, we discuss the potential bi-directional relationships between error processing and pain, and identify future directions to examine the neural and psychological processes involved in acute and chronic pain and respective avoidance behavior.

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

The error-related negativity (ERN) has been cited as a neural marker that indexes risk for anxiety in children and across development. Environmental factors, such as punishment in the lab and parenting styles, have been shown to impact the ERN. However, little is known about how other environmental factors may shape this neural risk marker. The current study examines how the environmental factor of stressful life events may relate to the ERN in children and adolescents. In a sample of 176 females, ages 8–15 years, we examined associations between the frequency of recent stressful life events and the ERN. We also investigated whether interpersonal dependent life events or non-interpersonal life events uniquely relate to the ERN. Finally, we explored whether recent stressors differentially relate to the ERN based on age. Results suggest that youth who have experienced more frequent stressful life events have an increased (i.e., more negative) ERN. Moreover, more frequent interpersonal dependent stressors uniquely predicted the magnitude of the ERN. Lastly, results supported a moderation model wherein the relationship between the frequency of interpersonal dependent stressors and the ERN was moderated by age, such that the relationship between stressors and the ERN was significant only for younger children.

On the relationship between the error-related negativity and anxiety in children and adolescents: From a neural marker to a novel target for intervention

The current review focuses on our work on the relationship between the error-related negativity (i.e., ERN) and anxiety in children and adolescents. The ERN is an event-related potential (ERP) that appears as a negative deflection in the ERP waveform when individuals make errors and has been found to be increased in anxious individuals. We, and others, have extended this work into developmental populations, finding that the ERN can be measured reliably in children and that the ERN is increased among clinically anxious youth. Furthermore, we have found that the ERN predicts risk for increases in anxiety across development, among healthy and clinically anxious children. We have done work to elucidate what psychological phenomena the increased ERN among anxious children may reflect by creating a self-report measure of error sensitivity (i.e., the Child Error Sensitivity Index) that relates to the ERN. Moreover, we review our work on parenting and the ERN, which suggests that harsh or critical parenting styles may potentiate the ERN in offspring. And, building on these findings, we discuss our recent work to develop novel, computerized intervention strategies to reduce the ERN and thereby risk for anxiety.

Is it a painful error? The effect of unpredictability and intensity of punishment on the error-related negativity, and somatosensory evoked potentials

We examined how predictable and unpredictable punishment intensity contingent on error commission modulated ERN amplitudes. We recorded the ERN in 35 healthy volunteers performing the Eriksen flanker task. Errors were punished with predictable nonpainful, painful or unpredictable electrical stimulation. Furthermore, we investigated trait anxiety. We observed that ERN amplitudes did not differ across conditions, nor were there significant effects of anxiety. In contrast, we found that predictable painful punishments led to smaller Error Positivity (Pe). The effects of predictability and intensity were present in Somatosensory Evoked Potentials elicited by the punishments. N1 amplitudes were increased for painful compared to nonpainful stimulation, and P2/P3 amplitudes for painful compared to nonpainful, and for unpredictable compared to predictable stimulation. We suggest that unpredictability and increased painfulness of punishments enhance the potential motivational significance of the errors, but do not potentiate ERN amplitudes beyond the ones elicited by errors punished with predictable nonpainful stimulation.

Correct response negativity may reflect subjective value of reaction time under regulatory fit in a speed-rewarded task

Error-related negativity (ERN), an electroencephalogram (EEG) component following an erroneous response, has been associated with the subjective motivational relevance of error commission. A smaller EEG event, the correct response negativity (CRN), occurs after a correct response. It is unclear why correct behavior evokes a neural response similar to error commission. CRN might reflect suboptimal performance: in tasks where speed is motivationally relevant (i.e., incentivized), a correct but slow response may be experienced as a minor error. The literature is mixed on the relationship between CRN and response time (RT), possibly due to different motivational structures, tasks, or individual traits. We examined ERN and CRN in a go/no-go task where correctness and speed were encouraged using a points-based feedback system. A key individual trait, regulatory focus, describes a person's tendency to seek gains (promotion focus) and avoid losses (prevention focus). Trait regulatory focus was measured, and participants were randomly assigned to one of three conditions: points gain, points loss, and informative-only feedback. Participants committed too few errors to reliably model ERN effects. CRN amplitude related to RT in all feedback conditions, with slower responses having larger CRN. Participants with stronger promotion focus had a more exaggerated RT/CRN relationship in the point gain condition, suggesting that regulatory fit influences the motivational relevance of speed and thus the negative subjective experience and CRN for slower responses. These findings are consistent with the claim that CRN reflects RT when RT is motivationally relevant and that the CRN/RT relationship reflects the degree of subjective motivational relevance.

Does attentional focus modulate affective information processing in male violent offenders with psychopathic traits?

Antisocial and psychopathic individuals are characterized by a reduced responsivity to affective information. Yet, the role of attentional processes as possible modulator of these deficits is poorly understood. The current study investigated early and late processing of emotional stimuli in a sample of incarcerated offenders while manipulating the attentional focus. Twenty-seven male violent offenders with psychopathic traits and 27 healthy controls completed two experimental tasks while electroencephalography (EEG) data were collected. Task 1 assessed indirect processing of emotional or neutral distractors during a perceptual judgment task, while Task 2 measured direct processing of the emotional or neutral stimuli and required participants to rate the stimuli regarding valence and arousal. EEG data indicated no differences in early stage processing (early posterior negativity) between the experimental groups. However, we found significant group differences with regard to the late processing stage (late positive potential, LPP). Controls showed increased LPP amplitudes in Task 2 as compared to Task 1, indicating that task demands (i.e., attentional focus) had an effect on the processing of the emotional stimuli. In contrast, LPP amplitudes in the violent offender group were largely unaffected by task demands, suggesting specific late alterations in the neural processing of emotional stimuli. In sum, this study provides new evidence for a modulatory impact of attention on affective information processing in male violent offenders with psychopathic traits.

Reliability of reward- and error-related brain activity in early childhood

Event-related potential (ERP) measures of reward- and error-related brain activity have emerged as potential biomarkers of risk for the development of psychopathology. However, the psychometric properties of reward- and error-related brain activity have been primarily investigated in adolescents and adults. It is critical to also establish the reliability of ERPs in younger children, particularly if they are used as individual difference measures of risk during key developmental periods. The present study examined the reliability of the reward positivity (RewP) and error-related negativity (ERN) among 80 children (M_age  = 6.9 years old; 50% female). Participants completed the doors, flanker, and go/no-go tasks twice, separated by approximately 8 months, while electroencephalography (EEG) was recorded. Results indicated that the RewP demonstrated strong internal consistency and test-retest reliability. The ERN also demonstrated strong internal consistency, but test-retest reliability was only significant for the ERN measured during the flanker task and not the go/no-go task. These results are largely consistent with reported psychometric properties of reward- and error related ERPs in adolescents and adults, suggesting that the ERN and RewP may be appropriate biomarkers of individual differences in populations ranging from early childhood to adulthood.

Event-related potential (ERP) measures of error processing as biomarkers of externalizing disorders: A narrative review

Previous studies have shown that electrophysiological measures of error processing are affected in patients at risk or diagnosed with internalizing disorders, hence, suggesting that error processing could be a suitable biomarker for internalizing disorders. In this narrative review, we will evaluate studies that address the role of event-related potential (ERP) measures of error-processing in externalizing disorders and discuss to what extend these can be considered a biomarker for externalizing disorders. Currently, there is evidence for the notion that electrophysiological indices of error processing such as the error-related negativity (ERN) and error positivity (Pe) are reduced in individuals with substance use disorders, attention-deficit/hyperactivity disorder, and in forensic populations. However, it remains unclear whether this is also the case for other understudied disorders such as behavioral addiction. Furthermore, to fully understand how these deficits affect day to day behavior, we encourage research to focus on testing current theories and hypotheses of ERN and Pe. In addition, we argue that within an externalizing disorder, individual differences in error processing deficits may be related to prognosis and gender of the patient, methodological issues and presence of comorbidity. Next, we review studies that have related treatment trajectories with ERP measures of error processing, and we discuss the prospect of improving error processing as a treatment option. We conclude that ERP measures of error processing are candidate biomarkers for externalizing disorders, albeit we strongly urge researchers to continue looking into the predictive value of these measures in the etiology and treatment outcome through multi-method and longitudinal designs.

Pain by mistake: investigating a link between error-related negativity and pain avoidance behavior

ABSTRACT

Pain can be considered as a signal of "bodily error": Errors put organisms at danger and activate behavioral defensive systems. If the error is of physical nature, pain is the warning signal that motivates protective action such as avoidance behavior to safeguard our body's integrity. Interestingly, an important component of neural error processing, the error-related negativity (ERN), has been found to be related to avoidance in anxiety disorders. The present study is the first to extend these findings to pain and investigate the relationship between ERN and pain-related avoidance behavior. It was hypothesized that individuals with larger ERN amplitudes would show more pain-related avoidance behavior and would be more persistent in their avoidance despite changes in the environment. Fifty-three healthy individuals performed the Eriksen Flanker task during which their brain activity upon correct and erroneous motor responses was recorded by means of high-density electroencephalography. Avoidance behavior was assessed with an arm-reaching task using the HapticMaster robot arm. Results showed that, in contrast to our hypothesis, avoidance was not related to ERN amplitudes. Surprisingly, persons with elevated ERN amplitudes showed low levels of avoidance specifically during early acquisition trials. In contrast to earlier findings in anxiety disorders, individuals with elevated ERN amplitudes did not engage in more pain-related avoidance behavior. In fact, the opposite pattern was found at the start of acquisition: individuals with higher compared to lower ERN amplitudes were slower in learning to avoid pain. Replications and future studies on the relationship between ERN and avoidance behavior are needed.

Sex Differences in Anxiety: An Investigation of the Moderating Role of Sex in Performance Monitoring and Attentional Bias to Threat in High Trait Anxious Individuals

Anxiety disorders are more predominant in women than men, however there is a lack of understanding as to what neurocognitive mechanisms drive this sex difference. Recent investigation has found a potential moderating role of sex in the relationship between anxiety and the error related negativity (ERN)—a component of error-monitoring that is prevalent in high anxiety individuals—such that females display a positive relationship between anxiety/worry and ERN amplitude. We strove to further explore the influence of sex on the relationship between trait anxiety and performance monitoring, specifically with ERN, as well as extend this work to include another hallmark of anxiety, attentional bias to threat. To meet this end, participants performed the flanker and dot-probe tasks, respectively. We did not find a significant difference in the relationship between attention bias scores and anxiety for female vs. males participants. Furthermore, ΔERN amplitudes were greater in males compared to females, and males had more positive CRN amplitudes than females. There were no significant associations between ERN or ΔERN with anxiety in both male and female participants. However, there was a significant relationship between CRN amplitudes and trait anxiety in male but not female participants. Given these results, the effect of sex on the relationship between components of performance monitoring—namely the CRN and ERN—and anxiety may be more nuanced than the current understanding. Our study was limited to detecting medium to large sized moderation effects. Our findings may be important for future meta-analysis on sex differences in anxiety.

The Relationship Between Childhood Stress and Distinct Stages of Dynamic Behavior Monitoring in Adults: Neural and Behavioral Correlates

Childhood adversity is a major risk factor for emotional and cognitive disorders later in adulthood. Behavior monitoring, one of the most important components of cognitive control, plays a crucial role in flexible interaction with the environment. Here, we test a novel conceptual model discriminating between two distinct dimensions of childhood adversity (i.e., deprivation and threat) and examine their relations to dynamic stages of behavior monitoring. Sixty young healthy adults participated in this study using event-related potentials (ERPs) and the dynamic stages of behavior monitoring including response inhibition, error detection, and post-error adjustments were investigated in a classical Go/NoGo task. Multiple regression analyses revealed that participants with higher severity of childhood adversity recruited more controlled attention, as indicated by larger (more negative) conflict detection-related NoGo-N2 amplitudes and larger (more negative) error detection-related ERN amplitudes. Higher severity of childhood abuse (an indicator of threat) was related to smaller (less positive) error appraisal-related Pe amplitudes on the neural level and subsequently lower post-error accuracy on the behavioral level. These results suggested that prefrontal-supported controlled attention is influenced by universal adversity in childhood while the error-related behavioral adjustment is mainly affected by childhood abuse, indicating the dimensions of deprivation and threat are at least partially distinct.

Examining the effect of perceived performance-contingent gains, losses and errors on arithmetic

Gains and losses have previously been found to differentially modulate Executive Functions and cognitive performance depending on performance contingency. Following recent findings suggesting that random gains and losses modulate arithmetic performance, the current study aimed to investigate the effect of perceived performance-contingent gains and losses on arithmetic performance. In the current study, an arithmetic equation judgment task was administered, with perceived performance-contingent gain, loss, and error feedback presented upon each trial. The results from two experiments suggest that when perceiving gain and loss as performance-contingent, the modulation of arithmetic performance, seen previously under random contingency conditions was entirely eliminated. In addition, another type of feedback was examined in the context of an arithmetic task: post-error adjustments. When performance after error feedback was compared to performance after other aversive performance feedback such as loss signals, only errors, but not other aversive feedback, modulated performance in the subsequent trial. These findings further extend the knowledge regarding the influence of gain and loss situations, as well as errors, on arithmetic performance.

Cognitive Control in Pediatric Obsessive-Compulsive and Anxiety Disorders: Brain-Behavioral Targets for Early Intervention

The DSM provides distinct criteria for obsessive-compulsive disorder (OCD) and various types of anxiety disorders, but phenomenological overlap, high rates of comorbidity, and early onset suggest common underlying mechanisms. This notion is further supported by use of the same treatments-cognitive behavioral therapy and serotonin reuptake inhibitor medication-for managing both OCD and non-OCD anxiety disorders in clinical settings. While early intervention with these gold standard treatments is recommended for pediatric OCD and anxiety disorders, young patients often remain symptomatic even after treatment. To guide the development of novel, mechanistically targeted treatments to better resolve OCD and anxiety symptoms, the identification of neural circuits underlying psychological constructs with relevance across disorders has been recommended. One construct that may be relevant for understanding pediatric OCD and anxiety disorders is cognitive control, given the difficulty that young patients experience in dismissing obsessions, compulsions, and worry despite recognition that these symptoms are excessive and unreasonable. In this review, we examine findings from a growing body of literature implicating brain-behavioral markers of cognitive control in pediatric OCD and anxiety disorders, including before and after treatment. We conclude by suggesting that interventions designed to enhance the functioning of the task control circuits underlying cognitive control may facilitate brain maturation to help affected youth overcome symptoms.

Pooling resources to enhance rigour in psychophysiological research: Insights from open science approaches to meta-analysis

Recent years have witnessed calls for increased rigour and credibility in the cognitive and behavioural sciences, including psychophysiology. Many procedures exist to increase rigour, and among the most important is the need to increase statistical power. Achieving sufficient statistical power, however, is a considerable challenge for resource intensive methodologies, particularly for between-subjects designs. Meta-analysis is one potential solution; yet, the validity of such quantitative review is limited by potential bias in both the primary literature and in meta-analysis itself. Here, we provide a non-technical overview and evaluation of open science methods that could be adopted to increase the transparency of novel meta-analyses. We also contrast post hoc statistical procedures that can be used to correct for publication bias in the primary literature. We suggest that traditional meta-analyses, as applied in ERP research, are exploratory in nature, providing a range of plausible effect sizes without necessarily having the ability to confirm (or disconfirm) existing hypotheses. To complement traditional approaches, we detail how prospective meta-analyses, combined with multisite collaboration, could be used to conduct statistically powerful, confirmatory ERP research.

A dimensional investigation of error-related negativity (ERN) and self-reported psychiatric symptoms

Alterations in error processing are implicated in a range of DSM-defined psychiatric disorders. For instance, obsessive-compulsive disorder (OCD) and generalised anxiety disorder show enhanced electrophysiological responses to errors-i.e. error-related negativity (ERN)-while others like schizophrenia have an attenuated ERN. However, as diagnostic categories in psychiatry are heterogeneous and also highly intercorrelated, the precise mapping of ERN enhancements/impairments is unclear. To address this, we recorded electroencephalograms (EEG) from 196 participants who performed the Flanker task and collected scores on 9 questionnaires assessing psychiatric symptoms to test if a dimensional framework could reveal specific transdiagnostic clinical manifestations of error processing dysfunctions. Contrary to our hypothesis, we found non-significant associations between ERN amplitude and symptom severity of OCD, trait anxiety, depression, social anxiety, impulsivity, eating disorders, alcohol addiction, schizotypy and apathy. A transdiagnostic approach did nothing to improve signal; there were non-significant associations between all three transdiagnostic dimensions (anxious-depression, compulsive behaviour and intrusive thought, and social withdrawal) and ERN magnitude. In these same individuals, we replicated a previously published transdiagnostic association between goal-directed learning and compulsive behaviour and intrusive thought. Possible explanations discussed are (i) that associations between the ERN and psychopathology might be smaller than previously assumed, (ii) that these associations might depend on a greater level of symptom severity than other transdiagnostic cognitive biomarkers, or (iii) that task parameters, such as the ratio of compatible to incompatible trials, might be crucial for ensuring the sensitivity of the ERN to clinical phenomena.

The Presence of a Controlling Parent Is Related to an Increase in the Error-Related Negativity in 5-7 Year-Old Children

Anxiety disorders often begin early in life and there is substantial interest in identifying neural markers that characterize developmental trajectories that result in anxiety. The error-related negativity (ERN) is elicited when people make errors on lab-based reaction-time tasks, is increased in anxious children, and can predict the onset of anxiety across development. In light of this, there is an increasing interest in identifying environmental factors that may shape the ERN in children. Previous work suggests that controlling parenting styles may relate to the ERN in offspring. However, no study had yet examined the specific mechanism whereby parenting style may impact the ERN in children. We propose that it may be children's repeated exposure to making mistakes in the context of their parents' reactions (i.e., verbal or non-verbal reactions, displays of parental control, etc.) that may lead to an increased ERN. We test this novel hypothesis by measuring the ERN in 94 children between the ages of 5-7 years old, while their parent observes them and then while an experimenter observes them complete a Go-No/Go task. Results suggest that the presence of parents characterized by high control potentiates the ERN in their children. Moreover, the relationship between controlling parenting styles and child anxiety disorder status was mediated by the parent presence potentiation of the ERN. These findings are important and novel insofar as they highlight the impact of an environmental factor (i.e., parenting) in shaping a neural marker of risk for anxiety in children (i.e., the ERN).

Moderating the Risk for Attention Deficits in Children with Pre-Adoptive Adversity: The Protective Role of Shorter Duration of out of Home Placement and Children's Enhanced Error Monitoring

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.

The error-related negativity (ERN) moderates the association between interpersonal stress and anxiety symptoms six months later

Anxiety disorders are often preceded by interpersonal stress; however, most individuals who experience stress do not develop anxiety, making it difficult to predict who is most susceptible to stress. One proposed trans-diagnostic neural risk marker for anxiety is the error-related negativity (ERN), a negative deflection in the event-related potential waveform occurring within 100 ms of error commission. The present study sought to investigate whether interpersonal stress experienced over the course of a year interacts with ERN magnitude to prospectively predict anxiety symptoms. A sample of 57 emerging adults performed an arrow flanker task to elicit the ERN at the start of the academic school year (time one). Toward the end of the academic year (time two), participants reported on past-year interpersonal stress and anxiety symptoms. Stress interacted with ERN magnitude to predict anxiety symptoms, whereby, for individuals with an enhanced ERN at time one, greater interpersonal stress over the course of a year was significantly associated with increased anxiety symptoms at time two, even controlling for anxiety symptoms at time one. These findings suggest that enhanced performance monitoring may render individuals more susceptible to the adverse effects of interpersonal stress, thereby increasing risk for heightened anxiety.

The Utility of Event-Related Potentials in Clinical Psychology

Event-related potentials (ERPs) are direct measures of brain activity that can be leveraged for clinically meaningful research. They can relate robustly both to continuous measures of individual difference and to categorical diagnoses in ways that clarify similarities and distinctions between apparently related disorders and traits. ERPs can be linked to genetic risk, can act as moderators of developmental trajectories and responses to stress, and can be leveraged to identify those at greater risk for psychopathology, especially when used in combination with other neural and self-report measures. ERPs can inform models of the development of, and risk for, psychopathology. Finally, ERPs can be used as targets for existing and novel interventions and prevention efforts. We provide concrete examples for each of these possibilities by focusing on programmatic research on the error-related negativity and anxiety, and thus show that ERPs are poised to make greater contributions toward the identification, prediction, treatment, and prevention of mental disorders.

Electrophysiological Evidence of Event-Related Potential Changes Induced by 12 h Abstinence in Young Smokers Based on the Flanker Study

The cognitive control processes may be disrupted by abstinence in smokers, which may be helpful in the development and maintenance of addictive behavior. The purpose of this study was to measure the performance of cognitive task after 12 h of smoking abstinence by using event-related potentials (ERPs), including the error-related negativity (ERN) and the error positivity (Pe). In Eriksen flanker task, electroencephalography (EEG) signals of 24 smokers were recorded in two conditions: satiety and 12 h abstinence. In the behavioral data, both conditions exhibited more errors and more time on the incongruent trials than congruence. Meantime, the Minnesota Nicotine Withdrawal Scale (MNWS) score was increased during abstinence. Smokers showed reduced ERN and Pe after 12 h of abstinence, compared with satiety condition. The results indicate that the diminished error processing in young smokers after 12 h of abstinence. It may be related to increased withdrawal symptoms. In conclusion, the disrupted neurophysiological indexes in the general behavior monitoring system may be caused by abstinence. The results of this study may provide us with new ideas about the effects of short-term abstinence on brain cognitive neuroscience and be helpful for the solution of relapse.

The relationship between chronic perceived stress and error processing: evidence from event-related potentials

Prolonged exposure to stress has a wide effect on the brain and cognition. Error processing, as one of the crucial components of executive function, plays an important role in cognitive and behavior control. However, to date, there is little research addressing the relationship between chronic perceived stress and error processing. The present study aims to explore the relationship between chronic perceived stress by the Cohen Perceived Stress Scale (PSS) and different stages of error processing by the method of Event-Related Potential (ERP). The error processing was tested in a classical auditory Go/NoGo paradigm, and ERP components including early Error-related Negativity (ERN) and late Error Positivity (Pe) were computed as the indices of error processing. The results showed that the PSS score was positively correlated with the Pe amplitude but not with the ERN amplitude. The correlation between PSS and the Pe amplitude holds true even after controlling the trait anxiety and depression symptoms. These results suggest that the higher the chronic stress level, the more sensitive the individuals are to their own errors as well as the more emotional/motivated attention the individuals distributed to their own errors.

The Impact of Unpredictability on Dyspnea Perception, Anxiety and Interoceptive Error Processing

Dyspnea is a prevalent interoceptive sensation and the aversive cardinal symptom in many cardiorespiratory diseases as well as in mental disorders. Especially the unpredictability of the occurrence of dyspnea episodes has been suggested to be highly anxiety provoking for affected patients. Moreover, previous studies demonstrated that unpredictable exteroceptive stimuli increased self-reports and electrophysiological responses of anxiety such as the startle probe N100 as well as amplified the processing of errors as reflected by greater error-related negativity (ERN). However, studies directly examining the role of unpredictability on dyspnea perception, anxiety, and error processing are widely absent. Using high-density electroencephalography, the present study investigated whether unpredictable compared to predictable dyspnea would increase the perception of dyspnea, anxiety and interoceptive error processing. Thirty-two healthy participants performed a respiratory forced choice reaction time task to elicit an interoceptive ERN during two conditions: an unpredictable and a predictable resistive load-induced dyspnea condition. Predictability was manipulated by pairing (predictable condition) or not pairing (unpredictable condition) dyspnea with a startle tone probe. Self-reports of dyspnea and affective state as well as the startle probe N100 and interoceptive ERN were measured. The results demonstrated greater dyspnea unpleasantness in the unpredictable compared to the predictable condition. Post hoc analyses revealed that this was paralleled by greater anxiety, and greater amplitudes for the startle probe N100 and the interoceptive ERN during the unpredictable relative to the predictable condition, but only when the unpredictable condition was experienced in the first experimental block. Furthermore, higher trait-like anxiety sensitivity was associated with higher ratings for dyspnea unpleasantness and experimental state anxiety ratings. The present findings suggest that unpredictability increases the perception of dyspnea unpleasantness. This effect seems related to increased state and trait anxiety and interoceptive error processing, especially when upcoming dyspnea is particularly unpredictable, such as in early experimental phases. Future studies are required to further substantiate these findings in patients suffering from dyspnea.

Approach, avoidance, and the detection of conflict in the development of behavioral inhibition

Motivation has played an integral role in understanding personality development. Two motivational systems, one associated with seeking reward (approach motivation) and one associated with avoidance of threat (avoidance motivation), have been theorized to represent individual differences in behavioral responses to the environment. However, contextual factors, particularly those with a high degree of novelty, ambiguity, and unpredictability, may simultaneously activate both systems, thereby causing approach-avoidance conflict. The resulting behavior, commonly called inhibition, is characterized by an inability to engage in motivated, goal-directed behavior and is theorized to reflect a core component of anxiety. A form of inhibition observed in childhood, behavioral inhibition (BI), is a relatively stable temperamental profile characterized by negative affect in response to unfamiliar and unpredictable contexts and is a risk factor for anxiety. Our review draws from findings in clinical and cognitive neuroscience to argue that BI reflects an increased sensitivity of both approach and avoidance motivational systems, thereby increasing the likelihood of approach-avoidance conflict within the context of unfamiliar or unpredictable stimuli and environments. Such motivational conflict activates neural systems associated with conflict monitoring, which leads to increases in arousal (e.g., sympathetic nervous system activity) and onlooking behavior, two commonly observed characteristics of childhood BI.

Social context effects on error-related brain activity are dependent on interpersonal and achievement-related traits

Brain correlates of performance monitoring, such as the Error-Related Negativity (ERN), are considerably influenced by situational factors. For instance, errors committed during social interaction typically elicit enhanced ERNs. While individual differences in ERN magnitude have been implicated in a wide variety of psychopathologies, it remains unclear how individual dispositions may interact with situational incentives to influence performance monitoring. Here, we analysed how interpersonal (Affiliation) and achievement-related (Agency) traits moderated the effects of interpersonal competition and interpersonal cooperation on the ERN. For this purpose, electroencephalography was collected from 78 participants while they performed a Flanker Task either in a competitive or in a cooperative social context (i.e., between-subjects design). We found that competition predicted enhanced error-related activity patterns compared to cooperation. Furthermore, participants who scored high in Affiliation elicited enhanced error-related activity. Conversely, high Agency scores were associated with reduced error-related activity, but this was only observed in the competitive context. These results indicate that the brain's response to error commission is not only sensitive to social incentives. Rather, the activity of the evaluative system that produces error signals appears to be crucially determined by the personal relevance of the incentives present in the context in which performance is evaluated.

Parenting style moderates the effects of exposure to natural disaster-related stress on the neural development of reactivity to threat and reward in children

Little is known about the effect of natural disasters on children's neural development. Additionally, despite evidence that stress and parenting may both influence the development of neural systems underlying reward and threat processing, few studies have brought together these areas of research. The current investigation examined the effect of parenting styles and hurricane-related stress on the development of neural reactivity to reward and threat in children. Approximately 8 months before and 9 months after Hurricane Sandy, 74 children experiencing high and low levels of hurricane-related stress completed tasks that elicited the reward positivity and error-related negativity, event-related potentials indexing sensitivity to reward and threat, respectively. At the post-Hurricane assessment, children completed a self-report questionnaire to measure promotion- and prevention-focused parenting styles. Among children exposed to high levels of hurricane-related stress, lower levels of promotion-focused, but not prevention-focused, parenting were associated with a reduced post-Sandy reward positivity. In addition, in children with high stress exposure, greater prevention-focused, but not promotion-focused, parenting was associated with a larger error-related negativity after Hurricane Sandy. These findings highlight the need to consider contextual variables such as parenting when examining how exposure to stress alters the development of neural reactivity to reward and threat in children.

Differences in Characteristics of Error-Related Potentials Between Individuals With Spinal Cord Injury and Age- and Sex-Matched Able-Bodied Controls

Background: Non-invasive brain-computer interfaces (BCI) represent an emerging technology for enabling persons with impaired or lost grasping and reaching functions due to high spinal cord injury (SCI) to control assistive devices. A major drawback of BCIs is a high rate of false classifications. The robustness and performance of BCIs might be improved using cerebral electrophysiological correlates of error recognition (error-related potentials, ErrPs). As ErrPs have never been systematically examined in subjects with SCI, this study compares the characteristics of ErrPs in individuals with SCI with those of able-bodied control subjects. Methods: ErrPs at FCz and Cz were analyzed in 11 subjects with SCI (9 male, median age 28 y) and in 11 sex- and age-matched controls. Moving a shoulder joystick according to a visual cue, subjects received feedback about the match/mismatch of the performed movement. ErrPs occurring after "error"-feedback were evaluated by comparing means of voltage values within three consecutive time windows after feedback (wP1, wN1, wP2 containing peak voltages P1, N1, P2) using repeated-measurement analysis of variance. Results: In the control group, mean voltage values for the "error" and "correct" feedback condition differed significantly around N1 (FCz: 254 ms, Cz: 252 ms) and P2 (FCz: 347 ms, Cz: 345 ms), but not around P1 (FCz: 181 ms, Cz: 179 ms). ErrPs of the control and the SCI group showed similar morphology, however mean amplitudes of ErrPs were significantly smaller in individuals with SCI compared to controls for wN1 (FCz: control = -1.55 μV, SCI = -0.27 μV, p = 0.02; Cz: control = -1.03 μV, SCI = 0.11 μV, p = 0.04) and wP2 (FCz: control = 2.79 μV, SCI = 1.29 μV, p = 0.011; Cz: control = 2.12 μV, SCI = 0.81 μV, p = 0.003). Mean voltage values in wP1, wN1, and wP2 did not correlate significantly with either chronicity after or level of injury. Conclusion: The morphology of ErrPs in subjects with and without SCI is comparable, however, with reduced mean amplitude in wN1 and wP2 in the SCI group. Further studies should evaluate whether ErrP-classification can be used for online correction of false BCI-commands in individuals with SCI.

The role of appearance attractiveness and loan amount in peer-to-peer lending: Evidence from event-related potentials

In recent years, peer-to-peer (P2P) lending has become a popular financial channel for raising capital. However, in contrast to traditional lending, in P2P lending, lenders must evaluate the risk of the loan application themselves with limited objective information and professional knowledge. Therefore, information which can be easily obtained may largely influence lenders' loan decisions, making lenders' decisions more subjective. Because appearance attractiveness is one of the most important personal characteristics, particularly for females, the current study was designed to investigate whether and how potential borrowers' appearance attractiveness influences investors' decisions in online P2P lending by using event-related potentials (ERPs). Our results showed that at the behavioral level, the lending decision for attractive borrowers is associated with shorter reaction times (RTs) than that for unattractive borrowers. In contrast, at the brain level, a large loan amount elicited a larger error-related negative (ERN) amplitude than a small loan amount for unattractive borrowers, which was not the case for attractive borrowers. This finding could be explained as the borrowers' appearance attractiveness modulating the lenders' risk perceptions in P2P lending because lenders are more tolerant when attractive borrowers default and because attractive females may convey more trustworthy impressions according to the theory of perceived risk.
