This study further examined the Gifted Rating Scales (GRS) at the internal and external stages of test validation by (a) testing structural fidelity as indicated by the number of factors supported as well as the correspondence of the latent factor structure with the scoring model proposed by the authors and (b) examining the external relations of…

First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…

Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is…

Rigorous evaluation of social and emotional learning programs requires the use of measures that provide reliable and valid information on the meaningful differences in children's social emotional skills across treatment and control groups, as well as changes over time. In contexts affected by conflict and crisis, few measures can provide the…

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students' readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the…

Early-life exposures are critical for later child cognitive development. McCarthy Scales of Children's Abilities (MSCA) were used to assess cognitive development of 700 preschoolers (M[subscript age] = 4.2 years), derived from the "Rhea" birth cohort, in Greece. Principal component analysis (PCA) was applied on prospectively collected…

The goal of this study was to examine the extent to which preschoolers with externalizing behavior problems (EBP) can identify behaviors indicative of callous-unemotional (CU) traits among their peers. Participants for this study included 86 preschool children (69% boys; M[subscript age] = 5.07 years) with at-risk or clinically elevated levels of…

This study tested whether individual executive function (EF) tasks were better characterized as formative or reflective indicators of the latent construct of EF. EF data that were collected as part of the Family Life Project (FLP), a prospective longitudinal study of families who were recruited at the birth of a new child (N = 1,292), when…

Despite acknowledgement of the importance of executive control for learning and behavior, there is a dearth of research charting its developmental trajectory as it unfolds against the background of children's sociofamilial milieus. Using a prospective, cohort-sequential design, this study describes growth trajectories for inhibitory control…

Purpose: To investigate a model of language development for nonverbal preschool-age children learning to communicate with augmentative or alternative communication. Method: Ninety-three preschool children with intellectual disabilities were assessed at Time 1, and 82 of these children were assessed 1 year later, at Time 2. The outcome variable was…

The purpose of this study was to examine the relationship of the variables of intelligence, creativity, and a language component in preschool disadvantaged Negro children. Major hypotheses were: (1) that the specific components of each variable had higher correlations within each variable than between variables; and (2) that each major loaded on a…

Explores children's play as social behavior in relation to cognitive style and identifies the social factors underlying both young children's play and cognitive style. Indicates that field-dependent children participated more in social play activities, while field-independent children engaged in more nonsocial play activities. Discusses the…

Language development was studied in 310 pairs of 4-year-old twins. Rotated factor analyses indicated presence of a general language factor (L) and a general nonverbal factor (NV). Moderate genetic influence was found for L and NV abilities. Bivariate genetic analysis estimated a genetic correlation of .63 between L and NV abilities. Results…

The project consisted of several independent sub-experiments focusing on factors that affect moral reasoning among young children. Preschool children, following brief training programs, reasoned more maturely about intentionality, punishment, sanctions following behavior, relativity, and immanent justice. Two methods of training were compared. In…

This study investigated (1) three kinds of mental operation in children: divergent production, convergent production, and cognitive thinking manifested in 3- to 4-year-olds and compared the results to results of a study of 4- to 5-year-olds, and (2) the relationship between children's abilities and their parents' level of education, children's sex…
