The late positive potential predicts emotion regulation strategy use in school-aged children concurrently and two years later.

The ability to use cognitive emotion regulation strategies such as reappraisal may be a core component of emotional competence across development, but due to methodological challenges in measuring such strategies, they are rarely studied in young children. One neurophysiological measure, the late positive potential (LPP), has been examined in response to reappraisal as a potential neurosignature for emotion regulatory capacity in adults. The association between the LPP and emotion regulatory capacity in children is unknown. The present study examined whether the LPP during reappraisal could predict greater observed adaptive emotion regulation strategy use in school-aged children over a two-year period. Thirty-two 5- to 7-year-olds participated in two identical lab visits spaced two years apart. EEG was continuously recorded during a computerized reappraisal task in which children viewed unpleasant images paired with either reappraisal or negative stories. Next they completed a disappointing and a frustrating task during which emotion regulation strategies were observed. As predicted, children who showed reappraisal-induced reductions in the LPP at the first assessment used significantly more adaptive ER strategies concurrently and two years later. These findings provide observation-based evidence that the LPP may be a viable neurosignature for emotion regulatory capacity in children.

Negative affectivity and EEG asymmetry interact to predict emotional interference on attention in early school-aged children.

Negative affectivity (NA) is a broad construct that has been associated with the development of psychopathologies, such as anxiety, and with exaggerated attention to threatening stimuli. EEG asymmetry reflects biological individual differences in emotional reactivity that may underlie the association between NA and attention to threat. The present study included a sample of 31 five-seven year olds (M age in months=74.39, SD=6.57) to test the hypothesis that greater NA, combined with greater right anterior and posterior asymmetries, predicts increased attention interference following threat stimuli. Children completed an executive attention task which presented task-irrelevant threat (angry) and non-threat (neutral) faces prior to each trial. EEG asymmetry was measured at baseline for anterior, anterior-temporal and posterior scalp regions and child NA was measured via maternal report. As predicted, children showing greater NA and greater right anterior-temporal asymmetry showed more attention interference following angry faces. Additionally, two trend-level effects emerged: children showing greater NA and greater left anterior-temporal asymmetry showed less attention interference following angry faces, and children showing greater NA and greater left posterior asymmetry showed less attention interference, but only following neutral faces. Discussion focuses on the utility of using EEG asymmetry in the study of temperament, attentional biases, and the biological processes by which temperament confers risk for psychopathology.

Attention training and the threat bias: an ERP study.

Anxiety is characterized by exaggerated attention to threat. Several studies suggest that this threat bias plays a causal role in the development and maintenance of anxiety disorders. Furthermore, although the threat bias can be reduced in anxious individuals and induced in non-anxious individual, the attentional mechanisms underlying these changes remain unclear. To address this issue, 49 non-anxious adults were randomly assigned to either attentional training toward or training away from threat using a modified version of the dot probe task. Behavioral measures of attentional biases were also generated pre- and post-training using the dot probe task. Event-related potentials (ERPs) were generated to threat and non-threat face pairs and probes during pre- and post-training assessments. Effects of training on behavioral measures of the threat bias were significant, but only for those participants showing pre-training biases. Attention training also influenced early spatial attention, as measured by post-training P1 amplitudes to cues. Results illustrate the importance of taking pre-training attention biases in non-anxious individuals into account when evaluating the effects of attention training and tracking physiological changes in attention following training.

The late positive potential: a neurophysiological marker for emotion regulation in children.

BACKGROUND: The ability to modulate emotional responses, or emotion regulation, is a key mechanism in the development of mood disruptions. Detection of a neural marker for emotion regulation thus has the potential to inform early detection and intervention for mood problems. One such neural marker may be the late positive potential (LPP), which is a scalp-recorded event-related potential reflecting facilitated attention to emotional stimuli. In adults, the LPP is reduced following use of cognitive emotion regulation strategies such as reappraisal. No studies to date have examined the LPP in relation to cognitive emotion regulation in children, and whether the LPP is related to parent-report measures of emotion regulation and mood disruptions. METHODS: To examine this question, high-density electroencephalograph (EEG) was recorded from 20 children (M age = 87.8 months, SD = 18.02; 10 girls) while they viewed unpleasant emotional pictures following either a directed negative or neutral interpretation of the picture. RESULTS: As predicted, the LPP was smaller following neutral versus negative interpretations at posterior recording sites, except for younger girls (aged 5-6). The timing of this effect was later than that reported in studies with adults. For all children, greater modulation of the LPP by neutral interpretations was associated with reduced anxious-depressed symptoms, whereas larger LPPs for both interpretation types were associated with greater mood symptoms and worse parent-reported emotion regulation. CONCLUSIONS: Results suggest that the LPP may represent a clinically relevant neural marker for emotion regulation and mood disruptions.

The functional organization of preschool-age children's emotion expressions and actions in challenging situations.

Although functional links between emotion and action are implied in emotion regulation research, there is limited evidence that specific adaptive actions for coping with a challenge are more probable when certain negative emotions are expressed. The current study examined this question among 3- and 4-year-olds (N = 113; M age = 47.84 months, SD = 6.19). Emotion expressions and actions were observed during 2 challenging tasks: children waited for a gift while the mother worked, and children worked alone to retrieve a prize from a locked box with the wrong key. Angry and happy expressions, compared with sad expressions, were associated with more actions. These actions varied with the nature of the task, reflecting appreciation of situational appropriateness. In addition, when waiting with the mother, happiness was associated with the broadest range of actions, whereas when working alone on the locked box, anger was associated with the broadest range of actions. Results are discussed in terms of the adaptive function of negative emotions and in terms of functional and dimensional models of emotion. Findings have implications for the development of emotion regulation and social-emotional competence.

Threat-related attentional biases: an analysis of three attention systems.

It is unclear how threat-related attentional biases affect multiple attention systems. This study used a new modification of a reaction time paradigm to examine whether inter-trial task-irrelevant fearful faces influenced the efficiency of alerting, orienting, and executive attention, and whether effects varied with level of state anxiety. Participants, 63 non-disordered adults (17 males and 46 females), reported on their subjective state anxiety and completed a modified version of the Attention Network Test in which fearful or neutral faces or control stimuli were presented briefly (50 ms) between trials of the task, but provided no task-relevant information. Across all participants, state anxiety was positively correlated with alerting, whereas fearful versus neutral faces were linked to decreased alerting efficiency. Contrasting high and low anxiety groups showed that fearful versus neutral faces reduced executive attention in the low state anxiety group only, suggesting decreased distraction by irrelevant stimuli in the high state anxiety group. Results document threat-related attentional biases that varied with attention system but failed to find enhanced bias effects among those with higher state anxiety in a typical range. This modification of the Attention Network Test, which added presentation of emotional distracters, provides a potentially useful new method for assessing the impact of task-irrelevant emotional stimuli on three aspects of attention performance.

Neurophysiological mechanisms in the emotional modulation of attention: the interplay between threat sensitivity and attentional control.

Processing task-irrelevant emotional information may compromise attention performance, particularly among those showing elevated threat sensitivity. If threat-sensitive individuals are able to recruit attentional control to inhibit emotional processing, however, they may show few decrements in attention performance. To examine this hypothesis, attention performance was measured in three domains--alerting, orienting, and executive attention. Task-irrelevant fearful, sad, and happy faces were presented for 50 ms before each trial of the attention task to create a mildly competitive emotional context. Electroencephalographic recordings were made from 64 scalp electrodes to generate event-related potentials (ERPs) to the faces. Participants reporting high threat sensitivity showed enhanced ERPs thought to reflect emotional processing (P200) and attentional control (P100 and N200). Enhanced N200 following fearful faces was linked to sustained and even slightly improved executive attention performance (reduced conflict interference) among high threat-sensitive individuals, but with decrements in executive attention among low threat-sensitive individuals. Results are discussed in terms of cognitive processing efficiency and the balance between threat sensitivity and attentional control in relation to executive attention performance. Results may have implications for understanding automatic and voluntary attentional biases related to anxiety.

Emotional face processing and attention performance in three domains: neurophysiological mechanisms and moderating effects of trait anxiety.

The rapid processing of emotional information adaptively regulates the allocation of attention, but may also divert resources away from attention performance, particularly for those showing elevated anxiety. The temporal organization of rapid emotional processing and its implications for attention performance, however, remain unclear. Participants were 18 healthy adults (12 females) who reported on trait anxiety. Tasks-irrelevant fearful, sad, and neutral faces were presented for 50 ms prior to each trial of a cued attention task measuring alerting, orienting, and executive attention. Electroencephalographic recordings were made from 64 scalp electrodes to generate event-related potentials (ERPs) to faces. Emotional face type and trait anxiety modulated ERP responses at three early stages around 200 ms, 250 ms, and 320 ms. Although behavioral findings showed enhanced orienting and executive attention following presentation of fearful and sad faces, the degree to which these faces modulated ERP responses, particularly around 250 ms, interfered with orienting and executive attention in the high trait anxiety group, and enhanced alerting in the low trait anxiety group. Results are discussed in terms of mechanisms in the emotional capture of attention and implications for understanding attentional processes in anxiety.

A Critical Review of Attentional Threat Bias and Its Role in the Treatment of Pediatric Anxiety Disorders.

Threat bias, or exaggerated selective attention to threat, is considered a key neurocognitive factor in the etiology and maintenance of pediatric anxiety disorders. However, upon closer examination of the literature, there is greater heterogeneity in threat-related attentional biases than typically acknowledged. This is likely impacting progress that can be made in terms of interventions focused on modifying this bias and reducing anxiety, namely attention bias modification training. We suggest that the field may need to "take a step back" from developing interventions and focus research efforts on improving the methodology of studying attention bias itself, particularly in a developmental context. We summarize a neurocognitive model that addresses the issue of heterogeneity by broadly incorporating biases toward and away from threat, linking this variation to key neurodevelopmental factors, and providing a basis for future research aimed at improving the utility of threat bias measures and interventions in clinical practice.

Associations between parental ideology and neural sensitivity to cognitive conflict in children.

Processes through which parental ideology is transmitted to children-especially at a young age prior to the formation of political beliefs-remain poorly understood. Given recent evidence that political ideology is associated with neural responses to cognitive conflict in adults, we tested the exploratory hypothesis that children's neurocognitive responses to conflict may also differ depending on their parents' ideology. We assessed relations between parental political ideology and children's neurocognitive responses to conflict, as measured by the N2 component of the event-related potential. Children aged 5-7 completed an age-appropriate flanker task while electroencephalography was recorded, and the N2 was scored to incongruent versus congruent flankers to index conflict processing. Because previous research documents heightened liberal-conservative differences in threat-relevant contexts, each trial of the task was preceded by an angry face (threat-relevant) or comparison face (happy or neutral). An effect of parental ideology on the conflict-related N2 emerged in the threat condition, such that the N2 was larger among children of liberals compared with children of moderates and conservatives. These findings suggest that individual differences in neurocognitive responses to conflict, heightened in the context of threat, may reflect a more general pattern of individual differences that, in adults, relates to political ideology.

Executive Function and Temperamental Fear Concurrently Predict Deception in School-Aged Children.

The decision to intentionally withhold truthful information, or deception, is a key component of moral development and may be a precursor to more serious anti-social tendencies. Two factors, executive function and temperamental fear are each thought to influence childhood deception. Few studies, however, have explored deception in relation to both of these factors simultaneously. This was the goal of the present study. Executive function, as measured by a working memory task, and temperamental fear, as measured via maternal report were assessed in relation to observed deceptive behavior among 6 - 9-year-old children (N = 43). Results showed that children displaying high working memory capacity and high temperamental fear were more likely to exhibit deceptive behavior. Implications for predictors of childhood deception and applications for moral education are discussed.

Effortful control, attention, and aggressive behavior in preschoolers at risk for conduct problems.

This work examines distinct aspects of effortful control and attention predicted aggression in a group of children at elevated risk for the development of conduct problems. Results suggested that behavioral inhibition, rather than attentional control, best predicted maternal reports of child aggressive behaviors.

Mental Health on the Go: Effects of a Gamified Attention Bias Modification Mobile Application in Trait Anxious Adults.

Interest in the use of mobile technology to deliver mental health services has grown in light of the economic and practical barriers to treatment. Yet, research on alternative delivery strategies that are more affordable, accessible, and engaging is in its infancy. Attention bias modification training (ABMT), has potential to reduce treatment barriers as a mobile intervention for stress and anxiety, but the degree to which ABMT can be embedded in a mobile gaming format and its potential for transfer of benefits is unknown. The present study examined effects of a gamified ABMT mobile application in highly trait anxious participants (N = 78). A single session of the active compared to placebo training reduced subjective anxiety and observed stress reactivity. Critically, the long (45 minutes) but not short (25 minutes) active training condition reduced the core cognitive process implicated in ABMT (threat bias) as measured by an untrained, gold-standard protocol.

The late positive potential as a neural signature for cognitive reappraisal in children.

The late positive potential (LPP), which is reduced following the use of reappraisal, is a potential neurosignature for emotion regulation capacity. This sensitivity of the LPP to reappraisal is rarely studied in children. We tested whether, in 26 typically developing seven- to nine-year-olds, LPP amplitudes were reduced following reappraisal and whether this effect varied with age and anxiety. For the full sample, LPPs were not significantly reduced following reappraisal. As predicted, reductions in the LPP following reappraisal were greater for older children and those showing less anxiety. The utility of the LPP as a neurosignature for emotion regulatory capacity is discussed.

The N170 to angry faces predicts anxiety in typically developing children over a two-year period.

Enhanced threat processing has been associated with elevated anxiety in adults, but less is known about how threat processing influences the developmental trajectory of anxiety in children. We used the N170 to measure threat (angry faces) processing in relation to child anxiety over a 2-year period. Participants were 27 typically developing 5-to-7-year-olds (13 females). Higher anxiety when children were aged 5 to 7 was associated with higher anxiety 2 years later, but only for children showing larger N170 amplitudes to angry versus happy faces. The N170 captures individual differences in threat processing that may characterize children at enhanced risk for anxiety.

Neurophysiological processing of emotion and parenting interact to predict inhibited behavior: an affective-motivational framework.

Although inhibited behavior problems are prevalent in childhood, relatively little is known about the intrinsic and extrinsic factors that predict a child's ability to regulate inhibited behavior during fear- and anxiety-provoking tasks. Inhibited behavior may be linked to both disruptions in avoidance-related processing of aversive stimuli and in approach-related processing of appetitive stimuli, but previous findings are contradictory and rarely integrate consideration of the socialization context. The current exploratory study used a novel combination of neurophysiological and observation-based methods to examine whether a neurophysiological measure sensitive to approach- and avoidance-oriented emotional processing, the late positive potential (LPP), interacted with observed approach- (promotion) and avoidance- (prevention) oriented parenting practices to predict children's observed inhibited behavior. Participants were 5- to 7-year-old (N = 32) typically-developing children (M = 75.72 months, SD = 6.01). Electroencephalography was continuously recorded while children viewed aversive, appetitive, or neutral images, and the LPP was generated to each picture type separately. Promotion and prevention parenting were observed during an emotional challenge with the child. Child inhibited behavior was observed during a fear and a social evaluation task. As predicted, larger LPPs to aversive images predicted more inhibited behavior during both tasks, but only when parents demonstrated low promotion. In contrast, larger LPPs to appetitive images predicted less inhibited behavior during the social evaluative task, but only when parents demonstrated high promotion; children of high promotion parents showing smaller LPPs to appetitive images showed the greatest inhibition. Parent-child goodness-of-fit and the LPP as a neural biomarker for emotional processes related to inhibited behavior are discussed.

Neural correlates of cognitive reappraisal in children: an ERP study.

Cognitive emotion regulation strategies, such as reappraising the emotional meaning of events, are linked to positive adjustment and are disrupted in individuals showing emotional distress, like anxiety. The late positive potential (LPP) is sensitive to reappraisal: LPP amplitudes are reduced when unpleasant pictures are reappraised in a positive light, suggesting regulation of negative emotion. However, only one study has examined reappraisal in children using the LPP. The present study examined whether directed reappraisals reduce the LPP in a group of 5- to 7-year-olds, and correlate with individual differences in fear and anxiety. EEG was recorded from 32 typically developing children via 64 scalp electrodes during a directed reappraisal task. Mothers reported on child anxiety. Fearful behavior was observed. As predicted, LPP amplitudes were larger to unpleasant versus neutral pictures;counter to predictions, the LPP was not sensitive to reappraisal. The degree to which unpleasant versus neutral pictures elicited larger LPPs was correlated with greater anxiety and fear. Results suggest that reappraisal in young children is still developing, but that the LPP is sensitive to individual differences related to fear and anxiety. The utility of the LPP as a measure of cognitive emotion regulation and emotional processing biases in children is discussed.

Emotional picture processing in children: an ERP study.

The late positive potential (LPP) reflects increased attention to emotional versus neutral stimuli in adults. To date, very few studies have examined the LPP in children, and whether it can be used to measure patterns of emotional processing that are related to dispositional mood characteristics, such as temperamental fear and anxiety. To examine this question,39 typically developing 5­7 year olds (M age in months = 75.27, SD = 5.83) passively viewed complex emotional and neutral pictures taken from the International Affective Picture System.Maternal report of temperamental fear and anxiety was obtained and fearful behavior during an emotional challenge was observed. As documented in adults, LPP amplitudes to pleasant and unpleasant stimuli were larger than to neutral stimuli, although some gender differences emerged. Larger LPP amplitude differences between unpleasant and neutral stimuli were associated with greater observed fear. The LPP as a measure of individual differences in emotional processing is discussed.

Error-monitoring brain activity is associated with affective behaviors in young children.

Despite recent evidence that neural correlates of error monitoring such as the error-related negativity (ERN) and error positivity (Pe) are visible in children sooner than previously thought, little is known about these components early in life. Error-monitoring components can be noninvasively recorded from a very early age and have been proposed as biological markers of risk for psychopathology. Therefore, the current study represents an attempt to examine the presence of these components in a sample of very young children and explore their associations with affect and attentional control.Fifteen children between ages 4 and 8 participated in two laboratory episodes: interacting with a stranger and completing a computerized flanker task. Shy and bold behaviors were scored during the stranger interaction and parents reported on temperament-based affective behaviors. Both ERN and Pe were visible in children as young as age 4. A trend-level interaction was observed between age and gender in association with ERN amplitudes. Age and gender were unrelated to the Pe. Greater ERN and Pe were associated with better poorer orienting and greater attentional focusing, respectively. Greater Pe was also linked to less observed boldness. Implications for studies of the development of performance monitoring in children are discussed.

The impact of task-irrelevant emotional stimuli on attention in three domains.

Whether task-irrelevant emotional stimuli facilitate or disrupt attention performance may depend on a range of factors, such as emotion type, task difficulty, and stimulus duration. Few studies, however, have systematically examined the influence of these factors on attention performance. Sixty-three adults, scoring within a normative range for mood and anxiety symptoms, completed either an easy or difficult version of an attention task measuring three aspects of attention performance: alerting, orienting, and executive attention. Results showed that in the easy task only, threatening versus nonthreatening task-irrelevant emotional faces facilitated orienting regardless of stimulus duration. These effects were no longer significant during the difficult condition. When the easy and difficult conditions were examined together, duration effects emerged such that stimuli of longer durations lead to greater interference, although effects were nonlinear. Findings illustrate that threat-relevant emotional stimuli facilitate attention during tasks with low cognitive load, but underscore the importance of considering a range of task parameters. Results are discussed in the context of adaptive and maladaptive emotion-attention interactions.
