Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

Few studies have used exploratory factor analysis (EFA) and exploratory bifactor factor analysis (EBFA) to define a baseline factor structure model checking the construct-relevant psychometric multidimensionality of student engagement. This study was conducted on a sample of 3,374 students in France, Wallonia-Brussels Federation, and Luxembourg by…

We compared the predictive validity of five aggregation methods for multiple informant data on child and adolescent behavior problems. In addition, we compared the predictive validity of these aggregation methods with single informant scores. Data were derived from the Minnesota Longitudinal Study of Parents and Children (N = 175). Maternal and…

The Emotion Matching Task (EMT; Izard, Haskins, Schultz, Trentacosta, & King, 2003) was developed to assess emotion knowledge in preschoolers and was demonstrated to show adequate convergent and predictive validity in an American sample (Morgan, Izard, & King, 2010). In light of the need for valid measures for assessing emotion…

Preschoolers' inhibitory control and early math skills were concurrently and longitudinally examined in 255 Chinese, African American, Dominican, and Mexican 4-year-olds in the United States. Inhibitory control at age 4, assessed with a peg-tapping task, was associated with early math skills at age 4 and predicted growth in such skills from age 4…

In this paper we present domain-specific measures of academic and social self-regulation in young adults. We base our scales on Baltes and colleagues' Selection, Optimization, and Compensation (SOC) model, and establish the factor structure of our new measures using data collected from a sample of 152 college students. We then compare the…

Aggressive behavior between children in schools is a topic that receives much interest as violence and aggressive behavior cause many maladaptive social outcomes in the school setting. In the current study the Implicit Association Test (IAT) was adapted as a measure of children's implicit aggression, by assessing the association of the self…
