The objective of this research was to develop robust predictive models of the gains in working memory (WM) and fluid intelligence (Gf) following executive attention training in children, using genetic markers, gender, and age variables. We explore the influence of genetic variables on individual differences in susceptibility to intervention.…

We describe the performance of 292 4- to 17-year-olds with Williams syndrome (WS) on the Kaufman Brief Intelligence Test-2 (KBIT-2; Kaufman & Kaufman, 2004). Mean IQ Composite, Verbal standard score (SS), and Nonverbal SS were in the borderline range relative to the general population, with variability similar to the general population.…

When threatened with ostracism, children attempt to strengthen social relationships by engaging in affiliative behaviors such as imitation. We investigated whether an experience of ostracism influenced the extent to which children imitated a partner's language use. In two experiments, 7- to 12-year-old children either experienced ostracism or did…

Multilevel modeling was used to address the longitudinal stability of standard scores (SSs) measuring intellectual ability for children with Williams syndrome (WS). Participants were 40 children with genetically confirmed WS who completed the Kaufman Brief Intelligence Test--Second Edition (KBIT-2; A. S. Kaufman & N. L. Kaufman, 2004) 4-7…

Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…

We evaluated the effects of student characteristics (sight word reading efficiency, phonological decoding, verbal knowledge, level of reading ability, grade, gender) and text features (passage difficulty, length, genre, and language and discourse attributes) on the oral reading fluency of a sample of middle-school students in Grades 6-8 (N =…

Purpose: This study attempted to determine whether there were any differences or similarities in the basic cognitive and language skills of 4 groups of adolescents: adjudicated (a judge's decision to establish responsibility for a delinquent act) and nonadjudicated male and females. Method: The 4 groups of adolescents were 18 adjudicated females,…
