Family is an important context for the development of adaptive child coping. Further, both family and child coping can promote positive mental health. This study examines whether family coping predicts child coping over 1 year among Mexican-origin immigrant families. Participants included 104 families with a child aged 6-10 years (M[subscript age]…

This study examined interparental conflict as a linear and curvilinear predictor of subsequent changes in adolescents' negative emotional reactivity and cortisol functioning during family conflict and, in turn, their psychological difficulties. In addition, adolescents' negative emotional reactivity and cortisol functioning during family conflict…

In the present research, we provide empirical evidence for the process of symbolic integration of number associations, focusing on the development of simple addition (e.g., 5 + 3 = 8), subtraction (e.g., 5 - 3 = 2), and multiplication (e.g., 5 × 3 = 15). Canadian children were assessed twice, in Grade 2 and Grade 3 (N = 244; 55% girls). All…

Although social difficulties have been identified as sequelae of children's experiences with interparental conflict and insecurity, little is known about the specific mechanisms underlying their vulnerability to social problems. Guided by emotional security theory, this study tested the hypothesis that children's emotional insecurity mediates…

Prosocial behavior in early childhood is a precursor to later adaptive social functioning. This investigation leveraged mother-reported, physiological, and observational data to examine children's prosocial development from age 2 to age 4 (N = 125). Maternal emotion socialization (ES) strategies and children's parasympathetic regulation have each…

Maternal instructional behavior at home and maternal ratings of children's temperament when children were 18 months old predicted mothers' problem-solving behaviors and children's performance on a cognitive problem-solving task at 30 months. Mothers' cognitive assistance to children during tasks at 18 and 30 months predicted children's cognitive…

This study investigated whether the process of representational change undergoes developmental change or different processes occupy different niches in the course of knowledge acquisition. Subjects--college, third-, and sixth-grade students--solved gear system problems over two sessions. Findings indicated that for all grades, discovery of the…

Examined whether indexes of verbal imprecision could be quantified and used to predict changes in fifth graders' problem-solving performance. Found that four types of verbal imprecision predicted improved performance: false starts and self-repairs, deletions, long pauses, and metacognitive comments. Results suggested that adopting a new approach…
