Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

The present study compared the course of parent-report and actigraphy-derived sleep profiles over a 1-year period, in school-age children with autism spectrum disorder and typically developing children. The Children's Sleep Habits Questionnaire and 14 nights of actigraphy were used to assess sleep profiles. Parents also completed the Spence…

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…

The purpose of this study was to analyze the performance of midwives based on the task commitment. This was an observational analytic with cross sectional approach. Multistage random sampling was used to determine the public health center, proportional random sampling to selected participants. The samples were 222 midwives in the public health…

Play is a fundamental concept in early childhood development and education. As partners in the child's learning, parents play a crucial role in how play is defined, valued, and practised. The present study explores the constructs of parents' beliefs about and engagement in young children's play in two coastal cities in China. A sample of 483…

This study aimed at investigating the effectiveness of televised children programs in the linguistic development of kindergarten children from the viewpoint of teachers. To achieve this, the researchers prepared the study instrument which is represented in a thirty-part questionnaire that was distributed to the study sample. The teachers'…

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…

Understanding the characteristics of preschool-age children is an important and first step for supporting children's healthy development and school readiness. Children may show different developmental features and come different social, socio-cultural background; however, they are in the same age. Reaching of education at a desired level will be…

Children's fine motor skills (FMS) are being increasingly recognized as an important aspect of preschool development; yet, we know very little about the experiences that foster their development. We utilized a parent-administered children's fine and gross motor activities questionnaire (MAQ) to investigate links with FMS. We recruited a sample of…

Parent- and lab-based observer ratings were employed to examine genetic and environmental influences on continuity and change in inhibitory control (IC) in over 300 twin-pairs assessed longitudinally at 2 and 3 years of age. Genetic influences accounted for approximately 60% of the variance in parent-rated IC at both ages. Although many of the…

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…

"Women's Mental Health Questionnaire" (W-MHQ) assesses females' adult mental health concerns, and examines their associations with specified father-daughter childhood relationships. Presented are W-MHQ item and scale development, and psychometric findings drawn from factor analyses, reliability assessments, and validation processes. For…

In a longitudinal study, we determine the beliefs of primary education students regarding the factors of academic achievement, good teachers, and the developmental characteristics of children, and we present which experiences mostly shape these beliefs. The same group of students (N = 59) completed the same questionnaire at the beginning of their…

Practice and Policy: The preschool years represent a critical time to foster family engagement in education for children growing up in poverty. Yet the ways in which Latino families with lower levels of income engage with their children's education at home and at school might look different from how middle-income parents from the dominant U.S.…

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…
