Machiavellian behavior and social-emotional functioning in middle childhood and early adolescence.

Machiavellianism is an antisocial interpersonal style involving the use of manipulative, deceptive, and coercive behaviors in the pursuit of self-interest. Although widely studied as a "dark" personality trait in adults, relatively little is known about the developmental correlates of Machiavellian tendencies earlier in life. The present study addressed this knowledge gap by examining associations between Machiavellian behavior and three theoretically relevant social-emotional domains-prosocial emotions, emotion recognition skills, and self-control-in a community sample of 7- and 11-year-old Canadian children (N = 300, 50% female). Of particular interest was the extent to which individual differences in social-emotional capacities were uniquely associated with Machiavellian behavior after controlling for aggression, a relatively well-studied antisocial behavior in childhood. Parents reported on children's Machiavellian behavior and aggression. Social-emotional correlates were assessed via parent and child reports, behavioral tasks, and physiological assessments. Machiavellian behavior and aggression were similarly associated with lower parent-reported prosocial emotions and self-control. Machiavellian (but not aggressive) behavior was associated with lower child-reported guilt (a prosocial emotion), higher resting skin conductance levels (reflecting a general tendency for higher arousal), and better anger recognition. Semipartial correlational analyses indicated that these patterns of association with Machiavellian behaviors held independent of aggression. These findings indicate that, by middle childhood, Machiavellian behavior constitutes a distinct form of antisocial conduct that is associated with a unique social-emotional risk profile.

Longitudinal analysis of sensory responsivity from infancy to school age in children at high and low familial likelihood for autism

AbstractBackgroundEmpirical evidence regarding the development of sensory responsivity in young children at high likelihood to develop autism spectrum disorder (ASD) remains relatively limited. It is unclear how sensory responsivity behaviors may change over time and impact later developmental outcomes. The goals of this study were to (a) characterize developmental trajectories of sensory responsivity across infancy (∼12 months), toddlerhood (∼24 months), and school age (6–11 years) in children at high and low familial likelihood for ASD; and (b) determine if sensory responsivity in infancy predicts adaptive and cognitive functioning at school age among children with ASD.MethodsGeneralized linear mixed effects models were used to examine scores from the Sensory Experiences Questionnaire in three groups of children including high‐likelihood children later diagnosed with ASD (HL‐ASD; n = 30), high‐likelihood children without ASD (HL‐Neg; n = 150), and low‐likelihood control children not meeting ASD diagnostic criteria (LL‐Neg; n = 94). Hierarchical linear regression was then used to examine the association between sensory responsivity scores in infancy and functional adaptive and cognitive outcomes at school age for children at high likelihood of ASD.ResultsDevelopment of sensory responsivity from infancy to later childhood is best estimated by the effects of chronological age and Group for Sensory Seeking and Hypo responsivity and the additional effect of the interaction of Group and chronological age for Total and Hyper responsivity. Early elevated Hypo responsivity and Sensory Seeking scores are negatively associated with later adaptive behavior but not cognitive level.ConclusionOverall, higher degrees of Sensory Seeking and Hypo sensory responsivity are detectable in autistic children's behavioral repertoires by 12 months of age and associate with reduced adaptive functioning in middle childhood. These results point to the potential importance of early detection and treatment implications of early sensory behaviors.

Long-term ozone exposure and lung function in middle childhood

BackgroundOzone (O3) exposure interrupts normal lung development in animal models. Epidemiologic evidence further suggests impairment with higher long-term O3 exposure across early and middle childhood, although study findings to date are mixed and few have investigated vulnerable subgroups. MethodsParticipants from the CANDLE study, a pregnancy cohort in Shelby County, TN, in the ECHO-PATHWAYS Consortium, were included if children were born at gestational age >32 weeks, completed a spirometry exam at age 8–9, and had a valid residential history from birth to age 8. We estimated lifetime average ambient O3 exposure based on each child's residential history from birth to age 8, using a validated fine-resolution spatiotemporal model. Spirometry was performed at the age 8–9 year study visit to assess Forced Expiratory Volume in the first second (FEV1) and Forced Vital Capacity (FVC) as primary outcomes; z-scores were calculated using sex-and-age-specific reference equations. Linear regression with robust variance estimators was used to examine associations between O3 exposure and continuous lung function z-scores, adjusted for child, sociodemographic, and home environmental factors. Potential susceptible subgroups were explored using a product term in the regression model to assess effect modification by child sex, history of bronchiolitis in infancy, and allergic sensitization. ResultsIn our sample (n = 648), O3 exposure averaged from birth to age 8 was modest (mean 26.6 [SD 1.1] ppb). No adverse associations between long-term postnatal O3 exposure were observed with either FEV1 (β = 0.12, 95% CI: −0.04, 0.29) or FVC (β = 0.03, 95% CI: −0.13, 0.19). No effect modification by child sex, history of bronchiolitis in infancy, or allergic sensitization was detected for associations with 8-year average O3. ConclusionsIn this sample with low O3 concentrations, we did not observe adverse associations between O3 exposures averaged from birth to age 8 and lung function in middle childhood.

Intimate partner violence exposure during infancy and social functioning in middle childhood: An Australian mother and child cohort study.

Social functioning of children with experiences of intimate partner violence (IPV) between caregivers in early childhood has received less attention than emotional-behavioral outcomes. Drawing on data from 1507 ten-year-old Australian-born children and their mothers participating in a community-based longitudinal study, this study examined the associations between IPV exposure during infancy and social development during middle childhood. IPV during the first 12 months of life was associated with lower social skills, higher peer problems, and peer victimization at age 10 years, while accounting for concurrent IPV. This study provides evidence for the long-term impacts of early-life IPV exposure on children's social functioning, and the importance of prevention and early intervention programs focused on social development following experiences of IPV.

Exposure to metal mixtures and neuropsychological functioning in middle childhood

Elevated exposure to multiple trace metals can be neurotoxic even at relatively low levels. These findings are primarily evident from adult occupational studies as well as in children exposed prenatally or in early childhood. Less research has focused on the neurodevelopmental impacts of exposure to metals among school-aged children. We examined associations between exposure to a mixture of four metals (arsenic, cadmium, manganese, lead) measured in hair and markers of cognition, attention, and behavior among 222 6–12 year old children who participated in a 2009–2010 neurodevelopmental follow-up to the C8 Health Project. Using quantile-based g-computation we estimated the adjusted overall metal mixture effect ψ (95 % CI) as the change in outcome per decile increase in all metals in the mixture. Hair metal levels varied by metal, with cadmium being lowest (median 0.007, interquartile range (IQR) 0.013 μg/g) and lead the highest concentration (median 0.152, IQR 0.252 μg/g). Children’s cognitive skills and development, attention/impulsivity, and behavior were all close to standardized population means. Each decile increase in all metals was associated with a Full Scale IQ reduction of 1.01 points (95 % confidence interval (CI) –1.88, –0.15) and Verbal IQ reduction of 1.11 points (95 % CI –1.97, –0.25), adjusted for child age, sex, secondhand smoke exposure, HOME score, maternal education, maternal IQ, and examiner. Maternal report of ADHD-like behaviors and executive functioning also showed adverse associations with the metal mixture. Our findings suggest that similar to exposure during prenatal and early childhood periods, recent exposure to metals during middle childhood is associated with adverse neurodevelopmental consequences. Middle childhood may also be a developmental window of susceptibility to the negative consequences of exposure to environmental neurotoxicants.

Secure attachment in infancy predicts context-dependent emotion expression in middle childhood.

Attachment security has been linked to healthy socioemotional development, but less is known about how secure attachment in infancy relates to emotional functioning in middle childhood, particularly across multiple contexts. The present study examined associations between secure attachment in infancy and children's context-dependent emotion expression during a parent-child interaction at age 9 (N = 78) among families with Child Protective Services involvement (i.e., children at risk for emotion dysregulation). The results indicated that children classified as securely attached in infancy exhibited less task-incongruent affect (i.e., less positive affect during a distressing discussion, less negative affect during a positive discussion) and a greater decrease in negative affect from a distressing discussion to a positive discussion than children classified as insecurely attached. In addition, secure children were rated as more appropriate in their emotion expression than insecure children. The present study highlights attachment as a promising intervention target for children at risk for emotion dysregulation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Exploring educators’ experiences of the social functioning of learners in middle childhood

In the research reported on here we explored educators’ experiences of learners’ social functioning in middle childhood in a South African context. Educators are important socialisation agents for learners in middle childhood, and we reasoned that they could offer valuable information to identify those key social skills and competencies that learners in this life phase need to function optimally. A qualitative exploratory design was used. Twenty-nine educators were purposefully selected as participants from 4 school districts in a demarcated area in the North-West province. Data were collected via 4 focus group interviews, with each focus group interview including the educators of 1 school per district. Thematic analysis of the data revealed the embeddedness of learners’ social functioning in the complex blend of South Africa’s unequal contexts and diverse cultures; the demonstration of inappropriate and appropriate behaviour as indicators of learners’ quality of social functioning in the learning environment; and the imperative to intentionally develop and strengthen the social skills and emotional competencies of learners in middle childhood. We recommend that learners in middle childhood be supported to acquire higher levels of social competence, in particular skills of communication and listening, conflict management, and problem-solving to improve innate social functioning.

Investigating the Associations between Family Alliance and Executive Functioning in Middle Childhood

ABSTRACT There is now wide consensus that the quality of family relationships is involved in the development of child executive functioning (EF), a set of cognitive skills that bear critical importance for social and academic adjustment at school. This body of research has, however, focused almost exclusively on dyadic parent-child interactions and failed to consider higher-level family processes. Consequently, the current study focused on family alliance, that is, the degree of coordination that father, mother, and child achieve while interacting together, as a predictor of individual differences in children’s EF. A community sample of 87 intact families (45 boys) participated in a triadic mother-father-child interaction when children were in kindergarten to assess family alliance. Children were assessed again when they were in Grade 4 with tasks of inhibition, cognitive flexibility, and working memory. Hierarchical regression analyses showed that higher-quality family alliance was predictive of better child performance on some cognitive flexibility and working memory tasks. These results indicate that some of the individual differences in child EF at school age may originate in the quality of the early family environment.

Psychological Well-Being and Family Functioning in Middle Childhood: The Unique Role of Sibling Relational Dynamics

Despite being the longest relationships across the lifespan, the sibling dyad is the most under-studied relationship in the family system. Researchers have documented the harmful and beneficial effects of sibling relationships and family dynamics on individual well-being. Extending this research to middle childhood, the current study examined family functioning, sibling relational dynamics, and self-reported adjustment and internalizing symptoms among 8- to 11-year-old children. Path analyses revealed significant direct effects between conflictual family functioning and children’s psychological well-being. Significant interactions between family functioning and sibling dynamics suggested that congruent relational dynamics at multiple levels of the family system had a cumulative impact on the child’s well-being. Findings from the current study highlight the role of family functioning and the unique contributions of sibling relationships to children’s functioning, suggesting that consideration of sibling relational dynamics may improve treatment planning by pointing out additional targets for intervention and/or potential sources of support.

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

BackgroundThe 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.MethodsThe 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.ResultsThe 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.ConclusionsThe 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.

Commentary on Guild et al. (2020): The Importance of Well-Designed Intervention Studies for Advancing Attachment Theory and its Clinical Applications.

Guild and colleagues (this issue) report results of a long-term follow up after a randomized trial of the effectiveness of an attachment-theory-informed psychotherapeutic intervention for mothers with depression and their toddlers. Their paper shows the intervention can increase the likelihood of secure attachment in children of depressed mothers and that secure attachment explains more optimal social-emotional functioning in middle childhood in the treated group. This commentary discusses the contribution of the paper by Guild and colleagues and their broader body of work to our evolving understanding of developmental processes underpinning social-emotional competence in children of depressed parents, and to several ongoing controversies in the field: 1) the relevance of attachment-theory-informed interventions in the context of maternal depression; 2) the evidence gap regarding the efficacy and effectiveness of attachment-theory-informed interventions, particularly with respect to sustained benefits; 3) cost-benefits of early interventions; and 4) the need for theory driven research that explains how and under what circumstances attachment is related to later child outcomes.

The role of inflammation in the association between poverty and working memory in childhood

BackgroundFamily financial difficulties have been directly linked to poorer executive functioning in childhood. However, recent studies suggest that difficulties in affording basic items and other necessities may also indirectly affect children’s executive functions through several psychological but also physiological paths. One of the latter may be inflammation, which has been related to both financial difficulties and executive functioning. In this study, we explored for the first time if the relationship between early family financial difficulties and working memory in middle childhood can be explained by inflammation. MethodsUsing data from 4,525 children of the Avon Longitudinal Study of Parents and Children, a general population birth cohort, we tested associations between parents’ perceptions at ages 0–3 years of having difficulties in affording basic items for their children including food and clothing, children’s inflammation [measured by interleukin 6 (IL-6) and C-reactive protein (CRP)] at age 9 years and working memory performance at age 10 years. Confounders included socioeconomic status at ages 0–3 years, economic hardship between ages 3–9 years, BMI and gender. ResultsUsing Structural Equation Modelling, we found that financial difficulties were associated with worse working memory (β=-0.076, 95 % CI=-0.105, -0.043) even after adjusting for confounders. This association was partially explained by inflammation (β=-0.002, 95 % CI=-0.005, -0.001) as measured by IL-6. ConclusionsChildren in families struggling to afford necessities early in life have higher levels of inflammation, in turn related to poorer executive functioning in middle childhood. These findings suggest that living under financial strain has a unique effect on children’s cognitive development through inflammation in the general population.

Early delay of gratification predicts later inhibitory control and academic performance in children with prenatal alcohol exposure

ABSTRACT Fetal alcohol spectrum disorder (FASD) affects 2–5% of the children in the United States. In the preschool age-range, inhibitory deficits frequently manifest as impaired ability to delay gratification, which is associated with deficits in cognitive flexibility in these children. The goal of this longitudinal study was to determine whether the ability to delay gratification in preschool children with FASD is (1) associated with broader manifestations in temperament and behavior; (2) predictive of later inhibitory control, cognitive flexibility and working memory in middle childhood; and (3) predictive of later parent-reported behavioral problems and school functioning in middle childhood. Forty-seven children with FASD, ages 2.5–5 years were administered a delay of gratification task in which they chose between receiving 2 snacks immediately or 10 snacks after waiting for 10 min. Two groups were defined based on a median split of waiting time. Four years later, 29 children completed measures of inhibitory control (Flanker task), cognitive flexibility (Dimensional Change Card Sort Test), and working memory (Stanford–Binet Intelligence Scales), and their parents completed the Child Behavior Checklist as a measure of the child’s behavioral problems and school functioning. Children with longer wait times on the delay of gratification task in preschool showed better inhibitory control on the Flanker task in middle childhood and better parent-reported school functioning in English. These findings indicate that early inhibitory capacity persists into middle childhood in those with FASD, and may be a promising target for early intervention to improve later cognitive outcomes in these children.

In Utero Exposure to Maternal Overweight or Obesity is Associated with Altered Offspring Brain Function in Middle Childhood.

The impact of in utero exposure to maternal overweight and obesity on offspring metabolic health is well documented. Neurodevelopmental outcomes among these children are, however, less well studied. To address this gap, the current study investigated brain function among 4- to 6-year-old children exposed to maternal overweight or obesity during gestation compared with that of children born to mothers with healthy BMI in pregnancy. Resting-state functional magnetic resonance imaging was used to study neuronal activity and connectivity during a passive viewing task (movie) among 101 typically developing children enrolled in the Healthy Start study, a longitudinal prebirth cohort in Colorado. Forty-nine children (48%) were exposed to maternal overweight or obesity in utero (mean age=5years, SD=0.9). Children born to mothers with overweight or obesity demonstrated hyperactivity in the left posterior cingulate cortex and hypoactivity in the dorsal anterior cingulate and the supplementary motor area (P<0.05 for all). Children born to mothers with overweight or obesity also showed ubiquitously weaker brain connectivity (P<0.05 for all). These novel results suggest altered brain function among children exposed to maternal overweight and obesity in utero.

Associations of Early Socio-familial Stress with Maladaptive and Adaptive Functioning in Middle Childhood: Roles of Executive Control and Foundational Cognitive Abilities.

This study examined whether cognitive processes in preschool, conceptualized as a unitary construct of executive control (EC) as well as foundational cognitive abilities (FCA), predict both maladaptive and adaptive functioning in middle childhood and mediate associations between early childhood socio-familial stress and those functional outcomes. Performance-based, multidimensional, and age-appropriate measures of EC and FCA were collected in a laboratory setting from 313 preschool-age children at age 5, along with questionnaire data from children and their parents on three dimensions of early socio-familial stress and parent smoking. Parent, teacher, and child self-report data on 285 of these children were obtained when they were in grade 3 or 4. Middle childhood data were used to create indices of maladaptive and adaptive functioning. A bi-factor structural equation modeling analysis captured distinct dimensions of preschool EC and FCA and was used to test the hypothesized pathways. EC had a statistically significant negative association with later maladaptive functioning. FCA, but not EC, served as a mediator in links between each type of family stressor and both maladaptive and adaptive functioning in middle childhood. Results suggest that EC may play a role in predicting maladaptation, whereas early childhood FCA may operate as an intervening variable in pathways from early family stressors to subsequent maladaptation as well as adaptation. Findings point to the need to address FCA by reducing early family stressors. Early interventions that enhance cognitive abilities may help reduce maladaptive and promote adaptive functioning later in childhood, thereby potentially preventing, in turn, later behavioral problems.

Early Brain Injury and Adaptive Functioning in Middle Childhood: The Mediating Role of Pragmatic Language.

Traumatic brain injuries (TBIs) often adversely affect adaptive functioning (AF). However, the cognitive mechanisms by which AF is disrupted are not well understood in young children who sustain TBI. This study examined pragmatic language (PL) and executive functioning (EF) as potential mechanisms for AF disruption in children with early, predominantly mild-complicated, TBI. The sample consisted of 76 children between the ages of 6 and 10 years old who sustained a TBI (n = 36) or orthopedic injury (OI; n = 40) before 6 years of age and at least 1 year prior to testing (M = 4.86 years, SD = 1.59). Children's performance on a PL and an expressive vocabulary task (which served as a control task), and parent report of child's EF and AF were examined at two time points 1 year apart (i.e., at age 8 and at age 9 years). Injury type (TBI vs. OI) significantly predicted child's social and conceptual, but not practical, AF. Results indicated that PL, and not expressive vocabulary or EF at time 1, mediated the relationship between injury type and both social and conceptual AF at time 2. A TBI during early childhood appears to subtly, but uniquely, disrupt complex language skills (i.e., PL), which in turn may disrupt subsequent social and conceptual AF in middle childhood. Additional longitudinal research that examines different aspects of PL and adaptive outcomes into adolescence is warranted.

Three pathways from anger dysregulation to lower social status among chinese boys

During middle childhood, Chinese boys are particularly at risk to develop both externalizing (e.g., overt aggression) and internalizing behavioral problems (e.g., social withdrawal). A possible contributor to these problems is that boys cannot regulate their anger very well. Inability to manage anger may cause a particular social challenge for Chinese boys. Open expression of anger may be prohibited by prevailing Chinese cultural norms, because it emphasizes individuality over harmony. But anger is a socially disengaging emotion which works against social harmony. This situation requires Chinese boys to manage and express anger appropriately in social interactions. Based on the hierarchical model of social relationships and the three trends of human interactions, this study examined three pathways—aggression, social withdrawal, and sociability-leadership—that lead from Chinese boys’ anger dysregulation to their lower social status among peers at school. Participants of this study were 267 boys in Grades 3-6 from an elementary school in urban China. A self-report questionnaire of anger dysregulation was used to evaluate how often Chinese boys express their anger in dysregulated ways (e.g., attacking things or people). Peer nominations were used to measure children’s overt aggression (moving against peers), social withdrawal (moving away from peers), and sociability-leadership (moving toward peers). Social status was assessed by a sociometric measure which evaluates the degree to which children were liked by their classmates. Results showed that boys’ anger dysregulation was negatively associated with their social status. Moreover, aggression, social withdrawal, and social skills fully mediated this association. This study enriches our understanding of the mechanisms linking anger dysregulation to lower social status and provides practical implications to help Chinese boys improve social and emotional functioning in middle childhood.
