Kindergarten children's attachment security, inhibitory control, and the internalization of rules of conduct

A Systematic Review on Attachment and Sleep at Preschool Age

Sleep is a biological process that impacts nearly every domain of a child's life. Sleep-wake regulation influences and it is highly influenced by developmental variables related to parent-child relationships, such as attachment. The main goal of the present systematic review is to analyze and integrate the findings of empirical studies investigating the relations between attachment and sleep in preschool age, a period marked by important developmental changes that challenge both attachment system and sleep-wake regulation. A database search was performed using a combination of relevant keywords, leading to the identification of 524 articles, with 19 manuscripts assessed for eligibility; finally, seven studies (2344 children) were included. Overall, the findings were not consistent, with some studies reporting significant associations between attachment security and sleep quality, as well as between attachment insecurity and sleep problems, whereas others did not find significant associations. The results are discussed in light of the available theoretical models and integrated in the context of measurement approaches to attachment and sleep heterogeneity, aiming to guide future research on the topic.

Affective temperaments and depressive symptoms: The mediating role of attachment

BACKGROUND

Studies showed that affective temperaments and attachment are associated with depressive symptoms, and that they bi-directionally influence each-other. The aim of this study is to explore mechanisms underlying the relationship between the affective temperaments (i.e., depressive, cyclothymic, irritable, hyperthymic and anxious), interview-based attachment, and depressive symptoms.

METHODS

A sample of 61 adolescents and young adults outpatients were asked to complete the Temperament Evaluation of Memphis, Pisa, and San Diego Autoquestionnaire (TEMPS-A) and the Hamilton Rating Scale for Depression (HAM-D). Attachment was assessed through the Adult Attachment Interview (AAI) and employing a dimensional approach to obtain continuous measures. Mediation models were performed with the affective temperaments as predictor, depressive symptoms as the criterion variable, and attachment dimensions as mediators.

RESULTS

Findings showed significant direct effects between all the affective temperaments and depressive symptoms. Only the cyclothymic (β = 0.22; SE = 0.1; 95% IC = 0.05, 0.42) and irritable (β = 0.21; SE = 0.09; 95% IC = 0.04, 0.4) temperaments showed an indirect effect on depressive symptoms through secure-insecure attachment. Dismissing attachment did not predict either the affective temperaments nor depressive symptoms. Preoccupied attachment significantly predicts depressive symptoms and, when controlling for it, the hyperthymic temperament no longer directly associates with depressive symptoms.

LIMITATIONS

The cross-sectional study design limit conclusion about causation and directionality.

CONCLUSIONS

Secure attachment could be a protective factor for depressive symptoms for individuals with a cyclothymic or irritable temperament. Differently, the hyperthymic temperament loses its protective role toward depressive symptoms when accounting for preoccupied attachment.

How Mother-Child Interactions are Associated with a Child's Compliance

While social interaction between a mother and her child has been found to play an important role in the child's committed compliance, the underlying neurocognitive process remains unclear. To investigate this process, we simultaneously recorded and assessed brain activity in 7-year-old children and in children's mothers or strangers during a free-play task using functional near-infrared spectroscopy-based hyperscanning. The results showed that a child's committed compliance was positively associated with the child's responsiveness but was negatively associated with mutual responsiveness and was not associated with the mother's responsiveness during mother-child interactions. Moreover, interpersonal neural synchronization (INS) at the temporoparietal junction mediated the relationship between the child's responsiveness and the child's committed compliance during mother-child interactions when the child's brain activity lagged behind that of the mother. However, these effects were not found during stranger-child interactions, nor were there significant effects in the mother-child pair when no real interactions occurred. Finally, we found a transfer effect of a child's committed compliance from mother-child interactions to stranger-child interactions via the mediation of mother-child INS, but the opposite did not occur. Together, these findings suggest that a child's responsiveness during mother-child interactions can significantly facilitate her or his committed compliance by increasing mother-child INS.

Inhibitory Control Mediates the Associations Between Parenting Practices and Depressive Symptoms in Adolescents: The Moderating Role of Catechol-O-Methyltransferase (COMT) Gene

Ample evidence suggested that parental responsiveness, demandingness, and autonomy granting protect adolescents from depressive symptoms. However, what is less well understood is how parenting practices reduce the risk of depressive symptoms. This study tested the protective effects of parenting practices and inhibitory control on depressive symptoms, along with the mediating role of inhibitory control and the moderating role of the COMT gene in linking parenting practices to depressive symptoms. The study utilized cross-sectional data from a community sample of Chinese Han adolescents (N = 943, M_age = 15.25 years, SD = 0.70 years; 51.9% girls). Results showed that parental responsiveness and autonomy granting promoted higher inhibitory control, which in turn was associated with lower depressive symptoms. Further, the mediation effects were moderated by the COMT gene. For adolescents with ValVal homozygotes, both responsiveness and autonomy granting were related to higher levels of inhibitory control, which reduced risk for depressive symptoms, but the mediation effects were not observed among Met allele carriers. The mediating role of inhibitory control did not hold in the parental demandingness model. Findings support the cognitive theory that inhibitory control is a proximal factor linking parenting practices to depressive symptoms exclusively in ValVal homozygotes. These results also suggested that differentiating different dimensions of parenting practices may help to further clarify the processes by which parenting practices eventuate depressive symptoms.

Cool and hot effortful control moderate how parenting predicts child internalization in Chinese families

Internalization of external rules is a behavioral manifestation of moral development during childhood, and its development has come to be understood from the view of a complex parenting-by-temperament process. To examine this developmental process, the current research investigated how maternal parenting behaviors and child effortful control foretell internalization throughout early to middle childhood with two longitudinal samples of Chinese mother-child dyads. In Study 1 (N = 226), maternal respect for autonomy and negative control during free plays at 15 months of age were observed. At 25 months, child cool and hot effortful control were measured with a Stroop-like categorization task and an externally imposed delay task. At 37 months, observed internalization of maternal rules was assessed. Results showed that for toddlers with high levels of cool effortful control, maternal respect for autonomy positively predicted later internalization. In Study 2 (N = 88), maternal respect for autonomy and negative control during free plays at 38 months of age were coded. At 60 months, child cool and hot effortful control were measured with a Stroop-like inhibition task and a delay-of-gratification task. Observed internalization of maternal and experimenter rules and mother-reported internalization in everyday life were assessed at 60 and 84 months. Results showed that for children low on either cool or hot effortful control, maternal respect for autonomy negatively predicted later internalization during childhood. Together, the current findings support an age-relevant goodness-of-fit model for internalization development in Chinese children throughout the first 7 years of life.

Attachment security, verbal ability, and inhibitory control in middle childhood

BACKGROUND

The relationship between parent-child attachment and executive function (EF) in middle childhood remains relatively poorly studied. Very little is known about the role that the child's verbal ability might play in these relationships. Therefore, in the present study, we explored the concurrent links between perceived attachment security with parents and hot and cool inhibitory control (IC)-a core component of EF-as well as the potential mediating role of verbal ability in those links.

METHODS

The participants were 160 children aged 8 to 12 (51% girls). They completed the Attachment Security Scale, the computerised version of the go/no-go task, the delay discounting task, and the vocabulary subtest from the Wechsler Intelligence Scale for Children. Pearson's correlations were conducted to test relationships between the study variables. A hierarchical multiple linear regression analysis was performed to examine whether attachment security uniquely contributed to the outcomes after accounting for covariates. The indirect effects were tested using a non-parametric resampling bootstrap approach.

RESULTS

The results showed that, after accounting for the child's age and sex, there was a direct relationship between attachment security with the father and cool, but not hot, IC. However, there were no significant links between attachment security with the mother and both aspects of IC. We also found that children's verbal ability played a mediating role in the associations between both child-father and child-mother attachment security and hot, but not cool, IC above and beyond the child's age.

CONCLUSIONS

The current study extends previous work on executive functions in middle childhood. The results highlight the role of attachment in explaining individual differences in IC in middle childhood as well as the different mechanisms through which attachment with parents might explain cool vs. hot IC. The findings have potential implications for therapeutic interventions using the family context as a target to improve IC in middle childhood.

Maternal Self-Construal, Maternal Socialization of Emotions and Child Emotion Regulation in a Sample of Romanian Mother-Toddler Dyads

Over the recent years, there is growing recognition of the social and cultural regulatory processes that act upon individual emotions. The adult-to-child social regulation of emotion is even more relevant, given the development of child self-regulatory abilities during early years. Although it is acknowledged that parental regulatory attempts to their children’s emotional expressions are influenced by cultural models, relatively little is known about the specific relationship between parental cultural models and socialization practices that foster emotion self-regulation, particularly in the case of toddlers. Therefore, in the present study, our first aim was to examine, in a Romanian sample of mother-toddler dyads, the relationships between maternal cultural model of self and maternal regulatory attempts targeting toddlers’ emotions during a delay of gratification task, while controlling for maternal perceptions of child individual characteristics, namely temperament. The second aim was to analyze, within the delay of gratification task, the relations between maternal regulatory attempts, child regulatory strategies and child affect expression, as the outcome of emotion regulation. Results showed that mothers scored higher for Independence as compared to Interdependence dimensions of self-construal. Also, the multidimensional analysis of self-construal revealed that Autonomy/Assertiveness scores were significantly higher than Relational Interdependent scores. Moreover, different dimensions of Independence predicted different maternal regulatory strategies employed during the delay of gratification task. This pattern of results suggests that maternal representations of an independent self, evidenced in our sample, are reflected in regulatory practices, aimed to develop primary control in the toddler. Moreover, our data revealed several significant associations between maternal regulatory strategies and child regulatory strategies expressed during the delay of gratification task. Finally, we demonstrated that child self-regulation mediated the relation between maternal regulatory attempts and child expression of affect during this task.

Psychological dysregulation during adolescence mediates the association of parent-child attachment in childhood and substance use disorder in adulthood

OBJECTIVE

This prospective study tested the hypothesis that psychological dysregulation in mid-adolescence (age 16) mediates the association between parent-child attachment in late childhood (age 10-12) and development of substance use disorder (SUD) in adulthood (age 22).

METHOD

The Youth Attachment to Parents Scale (YAPS) was developed in 10-12-year-old boys and girls (N = 694) at baseline residing in western Pennsylvania. Psychological dysregulation was measured by the neurobehavior disinhibition trait. Substance use was assessed at ages 10-12, 12-14, 16 and 19. SUD was diagnosed at age 22 using the Structured Clinical Interview for DSM Disorders. The mediation of parent-child attachment and SUD by neurobehavior disinhibition was tested separately for mothers and fathers while controlling for baseline substance use.

RESULTS

Psychological dysregulation mediates the association between attachment to mothers and SUD, and partially mediates the association between attachment to fathers and SUD. Significant mediation effects remains after controlling for baseline substance use.

CONCLUSION

Optimal prevention of SUD should include ameliorating both psychological dysregulation predisposing to SUD and quality of the parent-child relationship.
