Socialization of prosocial behavior: Gender differences in the mediating role of child brain volume

Evidence has been accumulating for the impact of normal variation in caregiving quality on brain morphology in children, but the question remains whether differences in brain volume related to early caregiving translate to behavioral implications. In this longitudinal population-based study (N = 162), moderated mediation was tested for the relation between parental sensitivity and child prosocial behavior via brain volume, in boys and girls. Both maternal and paternal sensitivity were repeatedly observed between 1 and 4 years of age. Brain volume was assessed using magnetic resonance imaging measurements at age 8, and self-reported prosocial behavior of children was assessed at 9 years of age. Parental sensitivity was positively related to child brain volume, and to child prosocial behavior at trend level. Child brain volume was negatively related to child prosocial behavior. A significant gender-by-brain interaction was found, illustrating that daughters of sensitive parents were more prosocial and that less prosocial behavior was reported for girls with a larger total brain volume. Child gender significantly moderated the indirect effect of parental sensitivity on prosocial behavior via total brain volume. A significant indirect pathway was found only in girls. The results warrant replication but indicate the importance of considering gender when studying the behavioral implications of differences in brain volume related to early caregiving experiences.     

Differential susceptibility experiments: going beyond correlational evidence: comment on beyond mental health, differential susceptibility articles

Reviewing the studies on differential susceptibility presented in this section, we argue that the time is ripe to go beyond correlational designs to differential susceptibility experiments. In such experiments, randomization prevents hidden moderator effects on the environment and guarantees the independence of moderator and outcome, while the environment is manipulated and assessed in standard ways. Correlational studies generate a priori expectations about crucial moderators (e.g., temperament, biological sensitivity, and genetics). We discuss the differential susceptibility experiments available up until now and conclude that these experiments are feasible and contribute in unique ways to our conceptions of differential susceptibility.     

Gender Stereotypes in the Family Context: Mothers, Fathers, and Siblings

Gender stereotypes of children and their parents were examined. Participants included 355 three-year-old children, their one-year-old siblings, and their mothers and fathers. Families were selected from the Western region of the Netherlands. Implicit gender stereotypes were assessed with computerized versions of the Action Inference Paradigm (AIP; both child and parents) and the Implicit Association Test (parent only). Parental explicit gender stereotypes were measured with the Child Rearing Sex-Role Attitude Scale. Findings revealed that mothers had stronger implicit gender stereotypes than fathers, whereas fathers had stronger explicit stereotypes than mothers. Fathers with same-gender children had stronger implicit gender stereotypes about adults than parents with mixed-gender children. For the children, girls’ implicit gender stereotypes were significantly predicted by their mother’s implicit gender stereotypes about children. This association could only be observed when the AIP was used to assess the stereotypes of both parent and child. A family systems model is applicable to the study of gender stereotypes.     

Parent-child relationship, temperament, and physiological reactions to fear-inducing film clips: further evidence for differential susceptibility

Recent studies have supported the intriguing hypothesis that highly reactive infants are most susceptible to the effect of parenting. This study replicates and extends an earlier study on 4-year-olds concerning higher susceptibility of more fearful children to the quality of their relationships with their mothers, as shown by their physiological reactions to fear-inducing film clips. Two groups of children (4- and 7-year-olds) were shown the same fear-inducing and neutral film clips. During the film clips, their skin conductance and heart rate variability were measured. Both 4- and 7-year-olds responded to the fear-inducing film clips with increases in skin conductance and decreases in heart rate variability. A secure relationship affected the reactivity to fearful stimuli in temperamentally more fearful children but not in less fearful children irrespective of children's ages. Our findings add to the growing literature showing that children high in negative emotion are more susceptible to positive as well as negative rearing influences for better and for worse.     

Asymmetric frontal brain activity and parental rejection predict altruistic behavior: Moderation of oxytocin effects

Asymmetric frontal brain activity has been widely implicated in reactions to emotional stimuli and is thought to reflect individual differences in approach–withdrawal motivation. Here, we investigate whether asymmetric frontal activity, as a measure of approach–withdrawal motivation, also predicts charitable donations after a charity’s (emotion-eliciting) promotional video showing a child in need is viewed, in a sample of 47 young adult women. In addition, we explore possibilities for mediation and moderation, by asymmetric frontal activity, of the effects of intranasally administered oxytocin and parental love withdrawal on charitable donations. Greater relative left frontal activity was related to larger donations. In addition, we found evidence of moderation: Low levels of parental love withdrawal predicted larger donations in the oxytocin condition for participants showing greater relative right frontal activity. We suggest that when approach motivation is high (reflected in greater relative left frontal activity), individuals are generally inclined to take action upon seeing someone in need and, thus, to donate money to actively help out. Only when approach motivation is low (reflected in less relative left/greater relative right activity) do empathic concerns affected by oxytocin and experiences of love withdrawal play an important part in deciding about donations.     

Joint Attention and Attachment in Toddlers with Autism

Joint attention is often referred to as a triadic relation between self, other and object. Young children with autism show deficiencies in the use of joint attention behaviors. Individual differences may be expected, and they may be determined by the children’s cognitive development or the characteristics of the relationship of the child with the caregiver. Although most joint attention skills develop under the age of three, most studies of joint attention in children with autism involved children older than 3 years of age, due to difficulties in diagnosing autism under this age. In this study we investigated joint attention behaviors of 78 young children (mean age 25.7 months, SD 6.1) with autism spectrum disorders (n = 20), other developmental delays (n = 18), and typically developing children (n = 40). Following the pertinent literature and confirmed by factor analysis, two types of joint attention behaviors were distinguished, Basic Joint Attention (BJA) and Associated Joint Attention (AJA). We found that cognitive delays and autistic symptoms—but not attachment insecurity or disorganization—were related to less joint attention. Already at the age of 2 years, children with more autistic symptoms show less joint attention, even after controlling for developmental level.     

Autism,Attachment and Parenting: A Comparison of Children with Autism Spectrum Disorder,Mental Retardation,Language Disorder,and Non-clinical Children

Children with Autism Spectrum Disorder (ASD) have severe and pervasive impairments in the development of social interaction, which may affect the attachment relationship with their parents and may have an impact on parenting. In the current investigation 89 families with young children (mean age 26.5 months) were involved, who were diagnosed as ASD, mentally retarded (MR), or language delayed (LD), or part of a non-clinical comparison group. Attachment security was observed with the Brief Attachment Screening Questionnaire, and several parental self-report questionnaires assessed the parenting style, parental efficacy, parental experiences of daily hassles, social support, and psychological problems. Children with ASD were rated as less secure compared to the other clinical and normal comparison groups. Parents of non-clinical children reported higher levels of authoritative parenting than parents in the ASD group and in the total clinical group, and they also received less social support. Parents of children with ASD coped remarkably well with the challenges of raising a child with ASD.     

Experimental manipulation of infant temperament affects amygdala functional connectivity

In this functional magnetic resonance imaging (fMRI) study we examined neural processing of infant faces associated with a happy or a sad temperament in nulliparous women. We experimentally manipulated adult perception of infant temperament in a probabilistic learning task. In this task, participants learned about an infant's temperament through repeated pairing of the infant face with positive or negative facial expressions and vocalizations. At the end of the task, participants were able to differentiate between “mostly sad” infants who cried often and “mostly happy” infants who laughed often. Afterwards, brain responses to neutral faces of infants with a happy or a sad temperament were measured with fMRI and compared to brain responses to neutral infants with no temperament association. Our findings show that a brief experimental manipulation of temperament can change brain responses to infant signals. We found increased amygdala connectivity with frontal regions and the visual cortex, including the occipital fusiform gyrus, during the perception of infants with a happy temperament. In addition, amygdala connectivity was positively related to the post-manipulation ratings of infant temperament, indicating that amygdala connectivity is involved in the encoding of the rewarding value of an infant with a happy temperament.     

Associations Between Dopamine D2 Receptor (<Emphasis Type="Italic">DRD2</Emphasis>) Gene,Maternal Positive Parenting and Trajectories of Depressive Symptoms from Early to Mid-Adolescence

Using data from the Longitudinal Study of Chinese Children and Adolescents (LSCCA), this study is the first to examine the roles of the dopamine D2 receptor (DRD2) gene polymorphisms (i.e., TaqIA and A241G) and maternal positive parenting at ages 10 and 11 years in the trajectories of depressive symptoms from early to mid-adolescence (ages 11 to 16 years). In a sample of 1090 Chinese adolescents (50% girls), three trajectories of depressive symptoms were identified: (i) low-stable (36.1%), (ii) moderate-increasing (44.5%), and (iii) high-increasing (19.4%). A241G AA homozygotes and youth exposed to lower levels of maternal positive parenting were both at increased odds to follow the high-increasing vs. low-stable trajectory. Moreover, the A241G polymorphism interacted with maternal positive parenting to distinguish the moderate-increasing trajectory from the high-increasing and the low-stable trajectories. For A241G G-allele carriers, but not AA homozygotes, exposure to high quality of maternal parenting decreased the odds to follow the high-increasing vs. moderate-increasing trajectory of depressive symptoms. For AA homozygotes, but not G-allele carriers, high quality of maternal parenting increased the odds to follow the low-stable vs. moderate-increasing trajectory. The DRD2 TaqIA polymorphism had neither a direct nor an interactive effect with maternal positive parenting on trajectory membership. The current findings highlight the importance of investigating gene-by-environment interactions (G × E) in trajectories of depressive symptoms over adolescence, and support a developmental versus static nature of G × E effects.
