Self-regulation and frontal EEG alpha activity during infancy and early childhood: A multilevel meta-analysis.

Integrating behavioral and neurophysiological measures has created new and advanced ways to understand the development of self-regulation. Electroencephalography (EEG) has been used to examine how self-regulatory processes are related to frontal alpha power during infancy and early childhood. However, findings across previous studies have been inconsistent. To address this issue, the current meta-analysis synthesized all prior literature examining associations between individual differences in self-regulation and frontal EEG alpha power (baseline and/or task). In total, 23 studies consisting of 1275 participants between 1 month and 6 years of age were included, which yielded 149 effect sizes. Findings of the three-level meta-analytic model demonstrated a non-significant overall association between self-regulation and frontal alpha power. Yet, significant moderating effects were found for self-regulation construct (emotion regulation, effortful control, executive function), self-regulation measurement (behavioral task, computer assessment, lab observation, questionnaire), and children's mean age. Self-regulation was only significantly correlated with frontal alpha power when studies focused on the executive functioning construct. Moreover, the use of behavioral tasks or questionnaires and a higher mean age of the children resulted in small but significant effect size estimates. Higher frontal alpha power values were related to higher order top-down mechanisms of self-regulation, indicating that these mechanisms might become stronger when the frontal cortex is sufficiently developed. The findings of the current meta-analysis highlight the importance of longitudinal analyses and multimethod approaches in future work to reach a more comprehensive understanding of the role of frontal EEG alpha activity in the etiology of individual differences in early self-regulation. RESEARCH HIGHLIGHTS: The first meta-analysis of individual differences in self-regulation and frontal EEG alpha power during infancy and early childhood demonstrated a non-significant overall association. Moderation analyses revealed that variations in frontal alpha power were significantly associated with executive function, but not with effortful control and emotion regulation. Frontal alpha power was related to variations in self-regulation when measured by behavioral tasks and questionnaires, but not via computer assessments and lab observations. The association between individual differences in self-regulation and frontal alpha power becomes significantly stronger with age.

Inhibitory Control Across the Preschool Years: Developmental Changes and Associations with Parenting.

The normative developmental course of inhibitory control between 2.5 and 6.5 years, and associations with maternal and paternal sensitivity and intrusiveness were tested. The sample consisted of 383 children (52.5% boys). During four annual waves, mothers and fathers reported on their children's inhibitory control using the Children's Behavior Questionnaire. During the first wave, mothers' and fathers' sensitivity and intrusiveness were observed and coded with the Emotional Availability Scales. Inhibitory control exhibited partial scalar invariance over time, and increased in a decelerating rate. For both mothers and fathers, higher levels of sensitivity were associated with a higher initial level of children's inhibitory control, whereas higher levels of intrusiveness predicted a slower increase in children's inhibitory control.

Individual differences in visual attention and self-regulation: A multimethod longitudinal study from infancy to toddlerhood.

Given the importance of self-regulation for a broad range of developmental outcomes, identifying reliable precursors of self-regulation early in development is important for early prevention of developmental problems. The aim of this study was to examine whether three visual attention measures (fixation duration, variation in fixation duration, and disengagement) in infancy (9.10-11.43 months of age) predicted effortful control and compliance in toddlerhood (26.71-31.80 months). The sample consisted of 74 children (50% boys). In infancy, two eye-tracking tasks were conducted: a visual search task to assess fixation duration and variation in fixation duration (n = 58) and the gap-overlap task to assess disengagement (n = 49). In toddlerhood, children's effortful control (n = 65) and compliance (n = 65) were assessed by parent reports and observed during a delay of gratification task and a cleanup session together with the parents, respectively. Using full information maximum likelihood to account for missing data, multiple regression analyses revealed that, when all three measures of visual attention were taken into account, longer fixations and less variation in fixation duration in infancy predicted better effortful control. Disengagement did not predict effortful control. Compliance in toddlerhood was not predicted by any of the visual attention measures. These findings may indicate that visual attentional measures in infancy predict relatively independent forms of self-regulation in toddlerhood. Future studies are necessary to elucidate the mechanisms that underlie the association between (variation in) fixation duration in infancy and effortful control in toddlerhood.

The Relation Between Trait Anger and Impulse Control in Forensic Psychiatric Patients: An EEG Study.

Inhibitory control is considered to be one of the key factors in explaining individual differences in trait anger and reactive aggression. Yet, only a few studies have assessed electroencephalographic (EEG) activity with respect to response inhibition in high trait anger individuals. The main goal of this study was therefore to investigate whether individual differences in trait anger in forensic psychiatric patients are associated with individual differences in anger-primed inhibitory control using behavioral and electrophysiological measures of response inhibition. Thirty-eight forensic psychiatric patients who had a medium to high risk of recidivism of violent and/or non-violent behaviors performed an affective Go/NoGo task while EEG was recorded. On the behavioral level, we found higher scores on trait anger to be accompanied by lower accuracy on NoGo trials, especially when anger was primed. With respect to the physiological data we found, as expected, a significant inverse relation between trait anger and the error related negativity amplitudes. Contrary to expectation, trait anger was not related to the stimulus-locked event related potentials (i.e., N2/P3). The results of this study support the notion that in a forensic population trait anger is inversely related to impulse control, particularly in hostile contexts. Moreover, our data suggest that higher scores on trait anger are associated with deficits in automatic error-processing which may contribute the continuation of impulsive angry behaviors despite their negative consequences.

Transmission of Cognitive Bias and Fear From Parents to Children: An Experimental Study.

This study explored the role of parents in the development of a cognitive bias and subsequent fear levels in children. In Experiment 1, nonclinical children ages 8-13 (N = 122) underwent a training during which they worked together with their mothers on an information search task. Mothers received instructions to induce either a positive or negative information search bias in their children. Experiment 2 investigated to what extent mothers own cognitive bias predicted children's information search bias. Mothers of 49 nonclinical children ages 9-12 received no explicit training instructions before working together with their child on an information search task. Experiment 1 demonstrated that mothers had a significant impact on children's cognitive bias and fear. More precisely, children who had received a negative parental training displayed an increase in negative information search bias and fear, whereas children who had received a positive parental training showed an increase in positive information search bias and a decrease in fear. In Experiment 2, it was found that children's information search biases after working together with their mothers were predicted by their mothers' initial cognitive bias scores. These findings can be taken as support for the intergenerational transmission of cognitive biases from mothers to children.

Are Child Abusers Sexually Attracted to Submissiveness? Assessment of Sex-Related Cognition With the Implicit Association Test.

Child sexual abuse is associated with social anxiety, low self-esteem, and intimacy deficits. This, in combination with the core belief of a dangerous world, might suggest that child abusers are sexually attracted to submissiveness. The Implicit Association Test (IAT) was used to examine this hypothesis. Results indicated that child abusers have a stronger sexual preference for submissiveness than rapists, although there were no differences between child abusers and non-sexual offenders. Multinomial logistic regression analysis revealed that submissive-sexy associations have incremental value over child-sex associations in differentiating child abusers from other offenders. The predictive value of both implicit associations was explored by correlating IAT scores with measures for recidivism risk, aggression, and interpersonal anxiety. Child abusers with stronger child-sex associations reported higher levels of interpersonal anxiety and hostility. More research on implicit cognition in sex offenders is required for a better understanding of what these and similar implicit measures are exactly measuring and what role implicit cognition may play in sexual offending.

Stability and change in maternal parenting profiles across infancy and toddlerhood.

During infancy and toddlerhood, parents show large individual differences in the extent to which they are able to tailor their parenting behaviors to their children's swiftly changing developmental needs. The first aim of our study was, therefore, to distinguish parenting profiles at three time points during infancy and toddlerhood (i.e., 5, 10, and 36 months) based on mothers' supportive presence, structure and limit-setting, and quality of instruction, as well as to examine the stability of profile structure and profile membership across time. The second aim was to examine how profile membership and profile transitions at each time point are associated with relevant parental, contextual, and child-specific factors. Data from 244 Dutch mother-child dyads were collected at three waves: when children were approximately 5 months (n = 203), 10 months (n = 181), and 3 years of age (n = 178). We found three types of parenting profiles at each wave: a competent profile, a sufficient profile, and a maladaptive profile. Only the competent parenting profile was found to have a stable structure across all three waves. In general, profile membership was least stable for the maladaptive profile. Results also showed that maternal agreeableness and a higher educational level increased the likelihood to exhibit a more competent parenting profile. Our findings advance our understanding of how parenting profiles might change due to children's swiftly changing needs and inform efforts to tailor parenting interventions to individual parents.

The assessment of an inhibited, anxiety-prone temperament in a Dutch multi-ethnic population of preschool children.

The Behavioral Inhibition Questionnaire-Short Form (BIQ-SF) is a 14-item parent-rating scale for assessing an inhibited, anxiety-prone temperament in preschool children. This study examined the psychometric properties of the BIQ-SF scores in a multi-ethnic community population of Dutch boys and girls aged 2.5-6 years (total N = 2,343, from which various subsamples were derived). Results revealed that the factor structure of the BIQ-SF was as hypothesized: a model with six correlated factors representing children's inhibited behaviors in various social and non-social contexts provided a good fit for the data. The internal consistency of the BIQ-SF was generally satisfactory and scores on the scale were found to be fairly stable over a time period of up to 2 years. Parent-teacher agreement was acceptable, and relations between the BIQ-SF and observations of an inhibited temperament were moderate. Finally, BIQ-SF scores were positively associated with measures of anxiety and internalizing symptoms, whereas no significant links were found with externalizing symptoms. Altogether, these results provide support for the reliability and validity of the BIQ-SF as an economical method for assessing behavioral inhibition and anxiety proneness in young children.

The direct and indirect effects of parenting behaviors and functional brain network efficiency on self-regulation from infancy to early childhood: A longitudinal mediation model.

There is growing interest in the hypothesis that early parenting behaviors impact children's self-regulation by affecting children's developing brain networks. Yet, most prior research on the development of self-regulation has focused on either environmental or neurobiological factors. The aim of the current study was to expand the literature by examining direct and indirect effects of variations in parenting behaviors (support and stimulation) and efficiency of functional brain networks (small-worldness) on individual differences in child self-regulation, using a three-wave longitudinal model in a sample of 109 infants and their mothers. Results revealed that parental support predicted child self-regulation at 5 months, 10 months, and 3 years of age. This effect was not mediated by infants' small-worldness within the alpha and theta rhythm. Parental stimulation predicted higher levels of infants' alpha small-worldness, whereas parental support predicted lower levels of infants' theta small-worldness. Thus, parents may need to stimulate their infants to explore the environment autonomously in order to come to more efficient functional brain networks. The findings of the current study highlight potential influences of both extrinsic environmental factors and intrinsic neurobiological factors in relation to child self-regulation, emphasizing the role of parental support as a form of external regulation during infancy, when the brain is not yet sufficiently developed to perform self-regulation itself.

Automatic affective appraisal of sexual penetration stimuli in women with vaginismus or dyspareunia.

INTRODUCTION: Current psychological views are that negative appraisals of sexual stimuli lie at the core of sexual dysfunctions. It is important to differentiate between deliberate appraisals and more automatic appraisals, as research has shown that the former are most relevant to controllable behaviors, and the latter are most relevant to reflexive behaviors. Accordingly, it can be hypothesized that in women with vaginismus, the persistent difficulty to allow vaginal entry is due to global negative automatic affective appraisals that trigger reflexive pelvic floor muscle contraction at the prospect of penetration. AIM: To test whether sexual penetration pictures elicited global negative automatic affective appraisals in women with vaginismus or dyspareunia and to examine whether deliberate appraisals and automatic appraisals differed between the two patient groups. METHODS: Women with persistent vaginismus (N = 24), dyspareunia (N = 23), or no sexual complaints (N = 30) completed a pictorial Extrinsic Affective Simon Task (EAST), and then made a global affective assessment of the EAST stimuli using visual analogue scales (VAS). MAIN OUTCOME MEASURES: The EAST assessed global automatic affective appraisals of sexual penetration stimuli, while the VAS assessed global deliberate affective appraisals of these stimuli. RESULTS: Automatic affective appraisals of sexual penetration stimuli tended to be positive, independent of the presence of sexual complaints. Deliberate appraisals of the same stimuli were significantly more negative in the women with vaginismus than in the dyspareunia group and control group, while the latter two groups did not differ in their appraisals. CONCLUSION: Unexpectedly, deliberate appraisals seemed to be most important in vaginismus, whereas dyspareunia did not seem to implicate negative deliberate or automatic affective appraisals. These findings dispute the view that global automatic affect lies at the core of vaginismus and indicate that a useful element in therapeutic interventions may be the modification of deliberate global affective appraisals of sexual penetration (e.g., via counter-conditioning).

CBM-I Training and Its Effect on Interpretations of Intent, Facial Expressions, Attention and Aggressive Behavior.

There is abundant evidence suggesting that attention and interpretation biases are powerful precursors of aggression. However, little is known how these biases may interact with one another in the development and maintenance of aggression. Using cognitive bias modification of interpretation (CBM-I), the present study examined whether training more pro-social or hostile intent attributions would affect attention bias, interpretation bias of facial expressions, aggression and mood. University students (17-48 years) were assigned to either a positive training (n = 40), negative training (n = 40), or control training (n = 40). Results showed that the positive training successfully changed measures of intent attributions in a pro-social direction compared to the control training. The negative training changed measures of intent attributions in a hostile direction but not more so than the control training. We found no generalization of the training effects to relevant other outcomes. Possible explanations underlying these findings are discussed.

The role of parental self-regulation and household chaos in parent-toddler interactions: A time-series study.

Various studies have reported that parental self-regulation is inversely related to negative parenting practices, especially in relatively calm households. These studies have focused on general tendencies of parents over longer periods of time. In the current time-series study, we extended previous work by focusing on the moment-to-moment processes in parent-child interactions that may explain associations between parental self-regulation, household chaos, and negative parenting practices. In a sample of 62 parent-toddler dyads (83.87% mothers), we tested whether observed contingent negative responses to child noncompliance (i.e., reactive negative parenting) could be predicted by the interaction between parental self-regulation and household chaos. Additionally, we examined whether two indicators of parental self-regulation, self-reported effortful control and task-based executive functioning, had similar associations with reactive negative parenting. Reactive negative parenting was assessed during clean up and was calculated as parents' propensity to show negative parenting practices immediately after their child showed noncompliance. We found that lower parental self-regulation predicted more reactive negative parenting practices in moderately chaotic households. Associations were similar regardless of whether self-regulation was operationalized as effortful control or executive functioning. The findings demonstrate that less regulated parents may benefit from a home situation that is tidy, calm, and characterized by routine in order to remain neutral in situations in which their toddler is noncompliant.

Contamination and harm relevant UCS-expectancy bias in spider phobic individuals: influence of treatment.

Phobic individuals expect aversive UCS's following encounters with phobic stimuli. Previous research using a thought-experiment procedure showed that contamination rather than harm-related outcome expectancies differentiated best between high and low spider fearful undergraduates. This study investigated the alleged role of these UCS-expectancy biases in the maintenance of phobic complaints. First, this study sought to replicate these earlier findings in a community sample of high spider fearful individuals who applied for treatment (n = 60) and a sample of low spider fear controls (n = 30). Second, the present study tested if UCS-expectancies disappear following successful treatment and whether there were any differences between harm and contamination-related UCS expectancies in this respect. If contamination- and/or harm-related UCS-expectancy biases play a critical role in the maintenance of spider fear, these biases should be substantially reduced after successful treatment. The results showed that spider fearful individuals associated spiders relatively strongly with both harm- and contamination-related outcomes. Consistent with the alleged reciprocal relationship between phobic fear and UCS expectancy bias, both types of biased expectancies were effectively reduced following treatment.

The YOUth study: Rationale, design, and study procedures.

Behavioral development in children shows large inter-individual variation, and is driven by the interplay between biological, psychological, and environmental processes. However, there is still little insight into how these processes interact. The YOUth cohort specifically focuses on two core characteristics of behavioral development: social competence and self-regulation. Social competence refers to the ability to engage in meaningful interactions with others, whereas self-regulation is the ability to control one's emotions, behavior, and impulses, to balance between reactivity and control of the reaction, and to adjust to the prevailing environment. YOUth is an accelerated population-based longitudinal cohort study with repeated measurements, centering on two groups: YOUth Baby & Child and YOUth Child & Adolescent. YOUth Baby & Child aims to include 3,000 pregnant women, their partners and children, wheras YOUth Child & Adolescent aims to include 2,000 children aged between 8 and 10 years old and their parents. All participants will be followed for at least 6 years, and potentially longer. In this paper we describe in detail the design of this study, the population included, the determinants, intermediate neurocognitive measures and outcomes included in the study. Furthermore, we describe in detail the procedures of inclusion, informed consent, and study participation.

Automatic and deliberate affective associations with sexual stimuli in women with superficial dyspareunia.

Current views suggest that in women with superficial dyspareunia the prospect of penile-vaginal intercourse automatically activates fear-related associations. The automatic activation of negative associations is assumed to interfere with the development of sexual arousal. In turn, this may further aggravate the dyspareunia-related complaints. To assess whether automatic negative associations are involved in this sexual pain disorder, women with superficial dyspareunia (n = 35) and a control group (n = 35) completed a modified pictorial Affective Simon Task (AST). Questioning the role of dysfunctional automatic associations in superficial dyspareunia, the AST indicated that symptomatic women displayed relatively positive rather than negative automatic associations with sexual stimuli. At the self-report level, however, affective associations with sex cues were significantly more negative for women with dyspareunia than for controls. This discrepancy between "reflective" and "reflexive" affective associations with sexual stimuli in women with dyspareunia points to the relevance of conscious appraisal and deliberate rather than automatic processes in the onset and maintenance of dyspareunia.

The effects of verbal disgust- and threat-related information about novel animals on disgust and fear beliefs and avoidance in children.

Disgust is a basic emotion that is thought to play a role in the etiology of certain types of specific phobias, like animal phobias. Two experiments were conducted in which 9- to 14-year-old children were exposed to disgust-related, cleanliness-related, and threat-related information about unknown animals. It was investigated to what extent these types of information influenced children's fear beliefs, feelings of disgust, and avoidance behavior in relation to the animals. Most important, results suggested a bidirectional relationship between disgust and fear. That is, disgust-related information was found to promote fear beliefs, and conversely threat-related information enhanced feelings of disgust. Repercussions of these findings for the role of disgust in the development and maintenance of anxiety pathology are discussed.

A dirty animal is a scary animal! Effects of disgust-related information on fear beliefs in children.

The present study investigated whether disgust-valenced information has an impact on children's fear beliefs about animals. Non-clinical children aged between 9 and 13 years (n=159) were presented with disgust-related and cleanliness-related information about unknown animals (Australian marsupials). Before and after information, beliefs of disgust and fear regarding the animals were assessed. Results showed that disgust-related information not only induced higher levels of disgust but also increased children's fear beliefs in relation to these animals. The other way around, cleanliness-related information decreased levels of disgust and resulted in lower levels of fear. The implications for the role of disgust in the development of animal fear are briefly discussed.

Does disgust enhance eating disorder symptoms?

In the present study, the hypothesized causal relationship between disgust and eating pathology was investigated. Female undergraduates were either assigned to an experimental condition in which feelings of disgust were induced by means of a bad smelling odorant, or to a control condition in which no such disgust manipulation was carried out. Both groups completed questionnaires for measuring various eating disorder-related concepts (i.e., body esteem, restraint eating, and body change strategies). In addition, explicit and implicit preferences for high-caloric food were measured. Results demonstrated that women in the experimental condition did not report lower levels of body esteem, and neither showed higher levels of restraint eating or other body change strategies. Furthermore, they did not display a decreased explicit or implicit preference for high-caloric food. Thus, in the present study no indication for a causal relation between disgust and eating disorder symptoms in young females was found.

A space odyssey: experimental manipulation of threat perception and anxiety-related interpretation bias in children.

This study provides a first test of an experimental method, the "space odyssey" paradigm, that was designed to manipulate interpretation bias in children. Seventy non-clinical children aged 8-12 years first completed a standardized anxiety questionnaire. Following this, they completed the space odyssey paradigm to induce either a negative or a positive interpretation bias. After this stage of interpretation training, children were presented with a series of ambiguous vignettes for which they had to rate perceived levels of threat as an index of interpretation bias. Results indicated that the space odyssey paradigm was successful in training interpretations: children in the negative training condition quickly learned to choose negative outcomes, while children in the positive training condition rapidly learned to select positive outcomes. Most importantly, children's subsequent threat perception scores for the ambiguous vignettes were affected by the manipulation. That is, children in the negative training condition perceived more threat than children in the positive training condition. Interestingly, the effects of training were most pronounced in high anxious children. Directions for future research with this paradigm are briefly discussed.

The effects of a novel hostile interpretation bias modification paradigm on hostile interpretations, mood, and aggressive behavior.

BACKGROUND AND OBJECTIVES: Cognitive theories of aggression propose that biased information processing is causally related to aggression. To test these ideas, the current study investigated the effects of a novel cognitive bias modification paradigm (CBM-I) designed to target interpretations associated with aggressive behavior. METHODS: Participants aged 18-33 years old were randomly assigned to either a single session of positive training (n = 40) aimed at increasing prosocial interpretations or negative training (n = 40) aimed at increasing hostile interpretations. RESULTS: The results revealed that the positive training resulted in an increase in prosocial interpretations while the negative training seemed to have no effect on interpretations. Importantly, in the positive condition, a positive change in interpretations was related to lower anger and verbal aggression scores after the training. In this condition, participants also reported an increase in happiness. In the negative training no such effects were found. However, the better participants performed on the negative training, the more their interpretations were changed in a negative direction and the more aggression they showed on the behavioral aggression task. LIMITATIONS: Participants were healthy university students. Therefore, results should be confirmed within a clinical population. CONCLUSIONS: These findings provide support for the idea that this novel CBM-I paradigm can be used to modify interpretations, and suggests that these interpretations are related to mood and aggressive behavior.
