Early exposure to parent-perpetrated intimate partner violence predicts hypervigilant error monitoring.

Early exposure to intimate partner violence (IPV) places children at risk for ongoing emotional difficulties, including problems with self-regulation and high levels of internalizing symptoms. However, the impact of IPV exposure on children's error monitoring remains unknown. The present study utilized electroencephalography (EEG) to examine the impact of exposure to IPV in infancy on error monitoring in middle childhood.

Unsupportive romantic partner behaviors increase neural reactivity to mistakes.

Romantic relationships involve a range of positive and negative experiences, from supportive and security-enhancing behaviors to unsupportive interactions involving criticism and dismissiveness. The present study aimed to examine the functional impact of these experiences on reactivity to mistakes, as error salience has key implications for adaptive functioning in areas such as goal-striving and appropriate risk-taking. To this end, a study was conducted in which participants completed the Eriksen Flanker Task (EFT) alone and under romantic partner observation while electrophysiological brain activity related to error salience (the error-related negativity (ERN)) was recorded.

Early parenting intervention accelerates inhibitory control development among CPS-involved children in middle childhood: A randomized clinical trial.

Children at risk for neglect or abuse are vulnerable to delays in inhibitory control development. Prior findings suggest that early parenting interventions that target parental sensitivity and responsiveness during infancy can improve executive function outcomes of high-risk children during preschool years; however, little is known about how persistent these gains are through middle childhood. Participants included 76 CPS-involved children who were randomly assigned to either the ABC intervention (N = 32) or the Developmental Education for Families (DEF) control intervention (N = 44), and 53 low-risk children.

Depressive symptoms and error-related brain activity in CPS-referred children.

Early adversity such as maltreatment is associated with increased risk for psychopathology and atypical neurological development in children. The present study examined associations between depressive symptoms and error-related brain activity (the error-related negativity, or ERN) among children involved with Child Protective Services (CPS) and among comparison children. Results indicate that the relation between depressive symptoms and ERN amplitude depends on CPS involvement, such that depressive symptoms were associated with blunted ERNs only for CPS-referred children.

Electrophysiological indicators of inhibitory control deficits in depression.

Ample evidence from behavioral and brain imaging studies suggests that inhibitory control is impaired in depression, though the precise nature of this impairment is unclear. The purpose of the present study was to examine potential deficits in three aspects of inhibitory control - conflict monitoring, conflict resolution, and overt behavioral inhibition - in the context of depressive symptoms. Depressed (n=15) and non-depressed (n=15) participants completed a stop-signal reaction time (SSRT) task while electroencephalography (EEG) data were recorded.

The power of frontal midline theta and post-error slowing to predict performance recovery: Evidence for compensatory mechanisms.

Past studies utilizing cognitive control tasks have noted that trials following errors are characterized by slowed reaction time. Despite the assumption long held by researchers that this slowing is compensatory (in the service of post-error performance recovery), studies consistently show that post-error trials are no more accurate than post-correct trials. As a result, it has recently been proposed that post-error slowing (PES) is merely part of an orienting response that serves no task-relevant cognitive control purpose.

Social value orientation modulates the FRN and P300 in the chicken game.

Social dilemmas pervade daily life, business, and politics. The manners in which these dilemmas are resolved depend in part on the personal characteristics of those involved. One such characteristic is Social Value Orientation (SVO), a trait-like predisposition to maximize cooperative (Pro-Social) or non-cooperative (Pro-Self) outcomes in social relationships.

How do we trust strangers? The neural correlates of decision making and outcome evaluation of generalized trust.

This study investigates the brain correlates of decision making and outcome evaluation of generalized trust (i.e. trust in unfamiliar social agents)-a core component of social capital which facilitates civic cooperation and economic exchange.

Pay attention to me! Late ERPs reveal gender differences in attention allocated to romantic partners.

The present study employed late ERPs to examine differences in the association between neural responses to romantic partners and relationship quality factors across men and women. Participants passively viewed photos of their romantic partners, celebrities, and strangers during a computerized facial processing task. All participants demonstrated enhanced positivity to partner faces at late ERP components (P3 and LPP), furthering the notion that significant others elicit more motivated and sustained attention than do other familiar or unfamiliar individuals.

Decreased response monitoring in individuals with symptoms of trichotillomania.

Trichotillomania (TTM) was long classified as an impulse-control disorder; however, the many characteristics it shares with obsessive-compulsive disorder (OCD) led to its recategorization in the DSM-V. The present study aimed to assess and inform the taxonomic placement of TTM through an examination of its neural correlates. While research has consistently associated OCD with enhanced response monitoring, the present study investigated whether a similar neural process is associated with TTM.

How friendly is a little friendly competition? Evidence of self-interest and empathy during outcome evaluation.

Although previous studies have shown that brain potentials recorded from passive observers differ when gambling-task outcomes are delivered to a friend or a stranger, it is unclear how these outcome evaluations are reflected in brain potentials during active competition. The present study recorded event-related potentials (ERP) from 16 normal adults playing an interactive gambling task against both a friend and a stranger. In this task, the P300 was modulated by the feedback valence (gain or loss) and the nature of the interpersonal relationship, such that it was larger when competing against strangers.

The N400 as an index of racial stereotype accessibility.

The current research examined the viability of the N400, an event-related potential (ERP) related to the detection of semantic incongruity, as an index of both stereotype accessibility and interracial prejudice. Participants' EEG was recorded while they completed a sequential priming task, in which negative or positive, stereotypically black (African American) or white (Caucasian American) traits followed the presentation of either a black or white face acting as a prime. ERP examination focused on the N400, but additionally examined N100 and P200 reactivity.

Response monitoring and cognitive control in childhood obesity.

The ability to discern when actions deviate from goals and adjust behavior accordingly is crucial for efforts at self-regulation, including managing one's weight. We examined whether children with obesity differed from controls in response monitoring, an aspect of cognitive control that involves registering one's errors. Participants performed a cognitive interference task, responding to the colors of arrows while ignoring their orientations, and error-related neural activity was indexed via response-locked event-related potentials (ERPs).

Electrophysiological responses to threat in youth with and without Posttraumatic Stress Disorder.

The current study was designed to examine event-related brain potentials and autonomic responses to pictures indicating threat, relative to non-threat, and acoustic startle reflexes in traumatized youth diagnosed with PTSD, relative to non-exposed children, before and after receiving psychotherapy. Children in the control group were individually yoked and demographically matched to the PTSD group. Both groups displayed enhanced late positive potentials and more prolonged heart rate deceleration to pictures indicating threat, relative to non-threat, and larger skin conductance responses to pictures indicating threat, relative to non-threat, at time one.

Interpretation of ambiguous social scenarios in social phobia and depression: evidence from event-related brain potentials.

In the current study, event-related potentials (ERPs) and behavioral responses were measured in individuals meeting diagnostic criteria for social phobia, depression, their combination, or neither in order to examine the unique and combined effects of social phobia and depression on the interpretation of ambiguous social scenarios. ERPs revealed a lack of positive interpretation bias and some suggestion of a negative bias in the semantic expectancy N4 component across all clinical groups. Furthermore, socially phobic and comorbid individuals showed reductions in baseline attention allocation to the task, as indexed by P6 amplitude.

Seeing the silver lining: potential benefits of trauma exposure in college students.

In the current study we compare college students exposed to a potentially traumatic event (PTE) meeting self-report criteria for Posttraumatic Stress Disorder (PTSD), PTE-exposed students not meeting criteria for PTSD, and non-exposed students on measures of perceived social support, self-esteem, and optimism (i.e., personal resources) and report use of specific coping strategies.

Cognitive inefficiency in depressive undergraduates: stroop processing and ERPs.

Evidence from neuroimaging studies indicates that depressive symptomatology is associated with inefficient recruitment of prefrontal brain regions while performing tasks that tax executive function. In the current study, we investigated the time-course and ERP signature of inefficient executive functioning using a verbal Stroop color-naming task. Twenty (20) undergraduates with moderate to severe BDI-II depression scores and 20 low-scoring controls completed the task.

Perceived parental support predicts enhanced late positive event-related brain potentials to parent faces.

This study examined event-related brain potentials in college students viewing facial pictures of their parents, celebrities, and strangers in the context of a guessing task. A temporal principal component analysis of data obtained from midline electrode sites was used to extract a component reflecting the mid- to late-positive deflection observed between 200 and 500ms following stimulus onset. Parent faces elicited enhanced positivity compared to celebrity and stranger faces suggesting greater attention allocation to parent faces.

Impaired anticipatory event-related potentials in schizophrenia.

Deficits in anticipation are implicated across a variety of cognitive and emotional processes in schizophrenia. Although diminished anticipatory event-related potentials (ERPs) have been detected during tasks requiring motor response preparation in schizophrenia, no prior ERP study has examined non-motor-related anticipatory processes or used motivationally engaging stimuli. Thirty-four schizophrenia outpatients and 36 healthy controls completed a cued, reaction-time contingent picture viewing task to assess two types of anticipatory ERPs, one involving motor response preparation (Contingent Negative Variation [CNV]) and one not involving motor preparation (Stimulus Preceding Negativity [SPN]).

Increasing negative emotions by reappraisal enhances subsequent cognitive control: a combined behavioral and electrophysiological study.

To what degree do cognitively based strategies of emotion regulation impact subsequent cognitive control? Here, we investigated this question by interleaving a cognitive task with emotion regulation trials, where regulation occurred through cognitive reappraisal. In addition to obtaining self-reports of emotion regulation, we used the late positive potential (LPP) of the event-related brain potential as an objective index of emotion regulation. On each trial, participants maintained, decreased, or increased their emotional response to an unpleasant picture and then responded to a Stroop stimulus.

Electrophysiological correlates of emotional responding in schizophrenia.

People with schizophrenia consistently report normal levels of pleasant emotion when exposed to evocative stimuli, suggesting intact consummatory pleasure. However, little is known about the neural correlates and time course of emotion in schizophrenia. This study used a well-validated affective picture viewing task that elicits a characteristic pattern of event-related potentials (ERPs) from early to later processing stages (i.

The way of our errors: theme and variations.

Negative feedback, either internal or external, is a fundamental guide to human learning and performance. The neural system that underlies the monitoring of performance and the adjustment of behavior has been subject to multiple neuroimaging investigations that uniformly implicate the anterior cingulate cortex and other prefrontal structures as crucial to these executive functions. The present article describes a series of experiments that employed event-related potentials to study a variety of processes associated with internal or external feedback.

Electrophysiological indicators of emotion processing biases in depressed undergraduates.

It has been proposed that depressed individuals are biased towards and have more difficulty disengaging from negative information once it has been made salient (e.g. Joormann, J.

The neural consequences of flip-flopping: the feedback-related negativity and salience of reward prediction.

Research suggests that the feedback-related negativity (FRN) is only sensitive to expectancy when the prediction violation is salient. To further examine this issue, we asked participants to guess which of two virtual doors hid 5 cents. Prior to and after making their guess, participants were asked whether or not they expected to win.

Electrophysiological correlates of decreasing and increasing emotional responses to unpleasant pictures.

We examined event-related brain potential (ERP) modulations during the anticipation and processing of unpleasant pictures under instructions to cognitively decrease and increase negative emotion. Instructions to decrease and increase negative emotion modulated the ERP response to unpleasant pictures in the direction of emotional intensity beginning around 400 ms and lasting several seconds. Decrease, but not increase, instructions also elicited enhanced frontal negativity associated with orienting and preparation prior to unpleasant picture onset.
