Differential Susceptibility or Diathesis-Stress: Testing the Moderating Role of Temperament and Cortisol Levels between Fathers' Parenting and Children's Aggressive Behavior

The Moderating Role of Cortisol and Negative Emotionality in the Effects of Classroom Size and Window View on Young Children's Executive Functions

This study probed how baseline cortisol (BC), negative emotionality (NE), and environmental facets-classroom size and window view-interact to affect executive function (EF) in preschoolers using virtual reality (VR). In a cohort of 144 children aged 61-85 months, BC levels were measured by saliva assays and NE by parental surveys. Participants completed computerized EF assessments both pre- and post-exposure to one of four VR conditions, which varied by classroom size (large vs. small) and window view (natural vs. built). Due to missing data and outlier responses, three children were removed from the analyses. Regression analyses, accounting for initial EFs, revealed that higher BC was significantly associated with better Digit-span task scores in the nature view, while lower BC correlated with improved performance in the built view. With regard to classroom size, children with varying levels of NE benefitted from the large classroom environment, as evidenced by marginally significant improvements on the Corsi block task. However, higher NE children outperformed their lower NE peers in the large classroom, while a trend inverted in the small classroom context. The findings illuminate how the physical components of preschool environments may interact with children's physiological reactivity, potentially influencing the development of working memory.

A person-centered approach to resilience and vulnerability in emerging adulthood: Predictions from parenting and personality in adolescence

In this person-centered study, we identified different profiles of resilience and vulnerability in emerging adulthood in response to previously experienced stressful life events. Additionally, we examined whether mothers' and fathers' parenting and participants' personality traits in adolescence predicted these profiles. Data from the Flemish Study on Parenting, Personality, and Development (N = 346 families) were used. At T1 (2004; Mage = 11 years), T2 (2007), and T3 (2009), mothers and fathers reported on their parenting and their child's personality. At T4 (2018; Mage = 25 years), emerging adults retrospectively self-reported the occurrence and impact of 22 stressful life events and rated current behavior problems and subjective well-being. Latent profile analysis revealed three profiles: Competent (71%; low stress, low behavior problems, high subjective well-being), Vulnerable (21%; average stress, high behavior problems, low subjective well-being), and Resilient (9%; high stress, average behavior problems, average subjective well-being). Emerging adults in the Resilient profile had experienced higher levels of maternal positive parenting and were less emotionally stable and conscientious than those in the Competent profile. Furthermore, emerging adults in the Vulnerable profile were less emotionally stable than their peers in the Competent profile. These findings reveal new insights into the heterogeneous patterns of emerging adults' adaptation following stressful life events.

The Moderating Role of Surgency, Behavioral Inhibition, Negative Emotionality and Effortful Control in the Relationship between Parenting Style and Children’s Reactive and Proactive Aggression

The principal aim of this study is to explore the moderating role of temperament in the relationship between parenting style and the reactive and proactive aggressive behavior of 8-year-old children. The participants are 279 children (154 boys and 125 girls). To measure reactive and proactive aggression, children completed the reactive and proactive questionnaire (RPQ). Child temperament and parenting styles were evaluated by both parents using the temperament in middle childhood questionnaire (TMCQ) and the parenting styles and dimensions questionnaire (PSDQ). The results revealed that boys with high surgency levels and authoritarian fathers displayed more reactive aggression, whereas behaviorally inhibited boys with mothers who scored low for authoritarian parenting displayed less reactive aggression. Finally, girls with high levels of effortful control and mothers who scored low for authoritative parenting displayed more proactive aggression. The results highlight the value of studying the moderating role of temperament in the relationship between children’s aggressive behavior and both mothers’ and fathers’ parenting styles, and underscores the importance of doing so separately for boys and girls.
