Previous research has found that when children engage in social and moral transgressions, they take steps to either remedy or explain their behavior. However, no prior systematic investigation has examined the strategies children employ to 'correct' their behavior in future situations. The present study employed a domain theory lens to investigate…

The current study identified alcohol and cannabis use trajectories among a sample of Mexican-origin youth and examined cultural and familial correlates from childhood to adolescence. Mexican-origin youth (N = 674) from Northern California were assessed annually from ages 10 to 17 (8 waves). Latent class growth modeling examined variability in…

Problem solving is a highly valued skill in chemistry. Courses within this discipline place a substantial emphasis on problem-solving performance and tend to weigh such performance heavily in assessments of learning. Researchers have dedicated considerable effort investigating individual factors that influence problem-solving performance. The…

This experimental study examined how the reading and writing development of sixth-grade L2 students was affected by syntactic enhancement. Visual-syntactic text formatting (VSTF) technology, which visualizes syntactic structures, was used to convert a textbook to the one with syntactic enhancement. The sample (n = 282), which was drawn from a…

Research examining child-care providers' beliefs and behaviour has produced contradictory evidence perhaps because analyses commonly examine providers as a homogenous group. Among providers in the Study of Early Child Care and Youth Development, we used cluster analysis to identify groups based on profiles of beliefs. We found evidence for five…

Variation in the parts of ASL signs (i.e., phonological variation) has been explained largely by reference to the influence of the preceding and the following segments. This article examines three linguistic variables in ASL: the sign deaf; the location of a class of signs represented by the verb know; and signs produced with a 1 handshape. For…
