Emotional Self-Regulation in Preschoolers: The Interplay of Child Approach Reactivity, Parenting, and Control Capacities.

This study examined whether child temperamental approach reactivity moderated the association between 2 factors, parenting and child control capacities and child emotional self-regulation. Participants (N = 113) were 3- and 4-year-olds (M = 48 months, SD = 5.78) and their mothers. Emotional self-regulation was measured as observed persistence and frustration and as maternal report of compliance. Parental approach, avoidance, control, and warmth were observed during play and a frustrating wait. Child approach reactivity and control capacities (inhibitory control and soothability) were assessed via maternal report. Results suggested that maternal approach during the wait was associated with persistence and frustration, whereas maternal warmth during the play was associated with compliance. These effects, and those of child control capacities, depended on the level of child approach. The implications of reactivity-control interactions and parent-child goodness-of-fit for emotional self-regulation are discussed.

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.

Prevention for preschoolers at high risk for conduct problems: immediate outcomes on parenting practices and child social competence.

This study investigated the immediate impact of an 8-month center- and home-based prevention program for preschoolers at high risk for conduct problems. We report immediate program effects on observed and self-rated parenting practices and observed child behavior with peers. Ninety-nine preschool-age siblings of adjudicated youths and their families were randomly assigned to an enhanced version of the Incredible Years Series (Webster-Stratton, 1989; n = 50) or to a no-intervention control condition (n = 49). In an intent-to-treat design, the intervention yielded significant effects on negative parenting, parental stimulation for learning, and child social competence with peers. Improvements in negative parenting, stimulation for learning, and child social competence support the potential of the intervention to prevent later conduct problems in high-risk children.

Brain potentials during affective picture processing in children

In adults, emotional (e.g., both unpleasant and pleasant) compared to neutral pictures elicit an increase in the early posterior negativity (EPN) and the late positive potential (LPP); modulation of these ERP components are thought to reflect the facilitated processing of, and increased attention to, motivationally salient stimuli. To determine whether the EPN and LPP are sensitive to emotional content in children, high-density EEG was recorded from 18 children who were 5-8 years of age (mean age=77 months, SD=11 months) while they viewed developmentally appropriate pictures selected from the International Affective Picture System. Self-reported ratings of valence and arousal were also obtained. An EPN was not evident following emotional compared to neutral pictures; however, a positivity maximal at occipital-parietal recording sites was increased from 500 to 1000 ms following pleasant pictures and from 500 to 1500 ms following unpleasant pictures. Comparisons between the EPN and LPP observed in children and adults, and implications for developmental studies of emotion, are discussed.

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.

Effortful control, social competence, and adjustment problems in children at risk for psychopathology.

This study explored the factor structure and developmental trajectory of effortful control (EC), its relations with child adjustment, and the moderating role of age and gender in 75 4- to 6-year-old children at risk for psychopathology. Confirmatory factor analyses revealed two subcomponents of effortful control: Suppress/Initiate (the ability to inhibit a dominant response while initiating a new response) and Motor Control (inhibiting fine and gross motor activity). EC performance improved with age, and both subcomponents were associated with greater social competence at all ages. Associations with internalizing problems were moderated by child age such that greater EC was linked to fewer problems at age 4 but did not relate to problems at ages 5 or 6.

Reactivity and regulation in children prenatally exposed to cocaine.

Children prenatally exposed to cocaine may be at elevated risk for adjustment problems in early development because of greater reactivity and reduced regulation during challenging tasks. Few studies have examined whether cocaine-exposed children show such difficulties during the preschool years, a period marked by increased social and cognitive demands and by rapid changes in reactivity and regulation. The authors addressed this question by examining frustration reactivity and regulation of behavior during a problem-solving task in cocaine-exposed and -unexposed preschoolers. Participants were 174 4.5-year-olds (M age = 4.55 years, SD = 0.09). Frustration reactivity was measured as latency to show frustration and number of disruptive behaviors, whereas regulation was measured as latency to approach and attempt the problem-solving task and number of problem-solving behaviors. Results indicated that cocaine-exposed children took longer to attempt the problem-solving task but that cocaine-exposed boys showed the most difficulties: They were quicker to express frustration and were more disruptive. Effect sizes were relatively small, suggesting both resilience and vulnerabilities.

Trait anxiety and conflict monitoring following threat: an ERP study.

Threat-related attentional disruptions in anxiety may relate to changes in cognitive control during task processing. The present study examined this question using the N2 event-related brain potential. It was predicted that threat stimuli will selectively influence the N2 for those showing elevated trait anxiety and that reduced N2 may reflect a compensatory process predicting better attention performance. EEG was recorded while 36 participants completed a cued flanker task with threat or nonthreat distracters. N2 amplitudes were greater to incongruent versus congruent flankers. Following threat, high trait anxious participants showed reduced modulation of the N2 by flanker type and greater N2 amplitudes to congruent flankers. Reduced N2 was associated with better attention performance. This study was among the first documenting the emotional modulation of the N2 related to the threat bias and its links with attention interference in anxiety.

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.

Self in Context: Autonomy and Relatedness in Japanese and U.S. Mother-Preschooler Dyads

Cultural differences and similarities in socialization during two contrasting laboratory tasks were examined in 30 Japanese mothers and their preschoolers, both temporarily residing in the United States, and 30 U.S. mothers and their preschoolers (age: M = 55.8 months, SD = 4.9). Mother and child actions, speech, emotion, and attention were coded from videotaped observations during a free play task and waiting task. Cross-cultural comparisons showed that U.S. mothers had more conversations that emphasized individual experiences, more often acted as playmates and used joint attention, maintained more physical distance, showed more positive emotions, and made more positive responses to child accomplishment. In contrast, Japanese mothers had more conversations that emphasized shared experiences, showed more divided attention, and maintained social role distinctions. Similar, but fewer cultural differences emerged for children. However, maternal and child characteristics also varied by task context. The results suggested an emphasis on autonomy in U.S. dyads and an emphasis on relatedness in Japanese dyads, but the interactions with task context revealed the coexistence of autonomy and relatedness.
