Self-regulation, or the ability to control one's actions and responses, is essential for healthy development across varied contexts. Self-regulation comes in several forms, including emotional, behavioral, and cognitive. The present study sought to examine whether individual differences in one form of self-regulation was related to children's…

Objective: Shaken Baby Syndrome (SBS) is now recognized as being the main cause of severe traumatic brain injury in infancy. However, our understanding of the impact of this type of abuse on child development remains sketchy. The main objective of the current study was therefore to shed light on the cognitive dysfunctions that are particular to…

[Slides] presented at the American Educational Research Association (AERA) in 2009. This study investigated the presence of a general rise in high school grades without a corresponding rise in SAT scores, as well as different grading criteria between schools, as shown by differential relationships between AP course grades and exam scores. These…

Students identified by talent search programs were studied to determine whether spatial ability could uncover math-science promise. In Phase 1, interests and values of intellectually talented adolescents (617 boys, 443 girls) were compared with those of top math-science graduate students (368 men, 346 women) as a function of their standing on…

In a longitudinal genetic study we explored which factors underlie stability in verbal and nonverbal abilities, and the extent to which the association between these abilities becomes stronger as children grow older. Measures of verbal and nonverbal IQ were collected in Dutch twin pairs at age 5, 7, 10, 12 and 18 years. The stability of both…

Background: The aim of the present study was to investigate how three different types of inhibitory control--interference control within task, interference control outside task, and prepotent response inhibition--and two types of working memory--verbal and spatial--would relate to early symptoms of attention deficit/hyperactivity disorder (ADHD)…

Previous correlational and experimental research has found a positive association between phonological awareness and reading skills. This paper provides an overview of studies in this area and shows that many studies have neglected to control for extraneous variables such as ability, phonological memory, pre-existing reading skills and letter…

This longitudinal study examined a comprehensive set of predictors of preschool language performance in a sample of children of adolescent mothers. Six domains of risk (low maternal verbal ability, intergenerational risk, contextual risk, relational risk, home environmental risk, and child characteristics) for poor preschool language development,…

In this study of the origins of individual differences in theory of mind (ToM), the Environmental Risk (E-Risk) Longitudinal Twin Study sample of 1,116 sixty-month-old twin pairs completed a comprehensive battery of ToM tasks. Individual differences in ToM were striking and strongly associated with verbal ability. Behavioral genetic models of the…

The article discusses a study by L. Terman in which results of the two methods can be compared. Both types of comparisons indicated that CMT (Concept Mastery Test) ability improves considerably with age. This multiple checking of several groups each time versus the same groups over time strengthens the conclusion. (Author/CL)

Relations between infant information processing and specific cognitive outcomes at age 11 years were examined in a sample of preterm and full-term infants. Seven-month visual recognition memory and 1-year cross-modal transfer predicted 11-year intelligence quotient (IQ). (MDM)

Using Ecological Systems Theory and stage sequential modelling procedures for detecting mediation, this study examined how early developmental contexts impact preschoolers' performances on a measure of sustained attention and impulse control. Data from 1273 European-American and African-American participants in the NICHD Study of Early Child Care…

Background: Children with fluent and accurate word reading in the presence of poor text comprehension are impaired on a wide range of reading-related tasks. Aims: This study investigated the consistency of skill impairment in a sample of poor comprehenders to identify any fundamental skill weakness that (i) might be associated with poor text…

The relationship between three quantitatively measured Thematic Apperception Test (TAT) scores in a longitudinal sample is examined for correlations and stability. (Author/DEP)

Describes a German longitudinal study of the relationship among verbal ability, memory capacity, phonological awareness, and reading performance. Reports that the relationship between memory capacity and phonological awareness remained stable over time. Concludes that memory capacity predicted phonological awareness task performance, phonological…
