Using data from undergraduates in both Turkey and the United States, we examined cultural differences in the perceived parenting authority styles and the links between perceived parenting authority styles, academic achievement, and self-esteem. We also examined the separate contributions of fathers and mothers in each country. A total of 423…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

This study examined early development of cool and hot self-regulation and how they were related to Chinese preschoolers' early achievement. A total of 951 children (448 girls) aged three to five in Hong Kong participated in this study. Children's self-regulation was assessed with a battery of five tasks tapping either cool or hot self-regulation;…

Infants exhibit visual preferences for gender-typed objects (e.g., dolls, toy vehicles) that parallel the gender-typed play preferences of preschool-aged children, but the developmental stability of individual differences in early emerging gender-typed preferences has not yet been characterized. In the present study, we examined the longitudinal…

This article reports a study that aimed to contribute to the theory of good toy design in terms of the value of using toys for children development. Moreover, the study attempts to evaluate ways in which children play and study the toys they commonly use with respect to how it influence their adulthood. The authors firstly looked into the…

This mixed two-way experimental, cross-sectional study investigated fast-mapping (FM) of novel nouns and verbs in 63 Persian-speaking toddlers aged 30 months, including 31 late-talking (LT) and 32 typically developing (TD) matched with respect to age and maternal education. Toddlers were classified as LT if they had limited expressive vocabulary…

This study examines the effects of acute alcohol intoxication on adolescents' school performance. In the 2007-2015 period, 3,317 adolescents (ages 12 to 17 years) were treated for acute alcohol intoxication, and 37 adolescents were admitted to the hospital twice. Alcohol intoxication has an overrepresentation in "low" school levels. The…

Inhibitory control (IC) and negative emotionality (NE) are both linked to aggressive behavior, but their interplay has not yet been clarified. This study examines different NE × IC interaction models in relation to aggressive behavior in 855 preschoolers (aged 2-5 years) using parental questionnaires. Hierarchical regression analyses revealed that…

This commentary discusses the articles that comprise this special issue on attachment in middle childhood. Central to this discussion is the distinction between verbal, strategic, and conscious responses to questionnaires as compared to verbal and nonverbal, automatic and largely unconscious responses to interviews. Both methods have been…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…

Although previous research has shown that homework improves students' academic achievement, the majority of these studies use data on students' homework time from retrospective questionnaires, which may be less accurate than time-diary data. We use data from the combined Child Development Supplement (CDS) and the Transition to Adulthood Survey…

We aimed to investigate stress response regulation, temperament, cognitive and language abilities and family SES in children who entered kindergarten before two years of age. Whilst childrens stress regulatory systems are vulnerable to environmental influences little is known about how temperament and family characteristics impact on stress…

No comprehensive studies have examined the utility of family drawings within the context of international adoption. We examined the relationship of Kinetic Family Drawings by 54 internationally adopted children in the USA (65% female; M age = 8.57 years, SD = 2.1) to demographics, child competencies (Child Behavior Checklist: CBCL/6-18) and…

The phenomenon of imaginary companions (ICs) has received little attention in developmental psychology, even though it can be observed in approximately 25% of preschool-aged children. Only a few studies have investigated the effect of ICs on children's theory of mind and emotion understanding, and the results are partial or inconsistent. This…
