Introduction: We examined the development of anxiety in youth with or without intellectual disabilities (ID). We also examined the effects of child delay status, temperament, ethnicity, and negative parenting on anxiety symptom trajectory. Method: Participants were 177 families in (blinded). We employed latent growth curve modeling to examine the…

Children with autism spectrum disorder have a high risk of vision problems yet little is known about their vision care. This cross-sectional survey study, therefore, examined vision care among 351 children with autism spectrum disorder ages 6-17 years in the United States or Canada who were enrolled in the Autism Treatment Network Registry. Vision…

Background: Oppositional Defiant Disorder (ODD) appears more prevalent among children with intellectual disabilities (ID) as compared to children with typical development. However, it remains unclear what drives this difference. Methods: Data from 70 youth with typical development (TD) and 20 youth with ID were drawn from (The Collaborative Family…

With just one exception, all of the volumes in Terman's Genetic Studies of Genius report the results of a longitudinal study of more than a thousand intellectually gifted children. That single exception is Volume II, Cox's single-authored "The Early Mental Traits of Three Hundred Geniuses," which instead was a retrospective study of 301…

This paper analyses how high-stakes, standardised testing became the policy tool in the U.S. that it is today and discusses its role in advancing an ideology of meritocracy that fundamentally masks structural inequalities related to race and economic class. This paper first traces the early history of high-stakes testing within the U.S. context,…

The relative difficulty levels of Stanford-Binet items between the ages of four and six among prekindergarten Head Start children were studied. A comparison sample of prekindergarten white middle class children was included to evaluate the age norms on a culturally typical sample of children and to assess performance on the Binet as it might…

The hypothesis that four measures selected to represent the field dependence-independence construct would be positively intercorrelated was supported by the presence of statistically significant positive correlation coefficients in the total sample as well as in the subgroups differentiated by ethnicity, intelligence level, and sex.

Examined theoretical model of early environmental action of 282 Caucasian and African American infants, using structural equation modeling. Model included socioeconomic status, early cognitive status, stimulation with home environment, parental use of negative control, and later cognitive status. Models for males and females showed similar…

The authors introduce readers to the research documenting racial and ethnic gaps in school readiness.

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…

The influence of race on IQ was studied with 33 European American and 33 African American 3-year olds matched for several characteristics. Findings of a difference favoring European Americans support the Spearman hypothesis that group performance differences on subtests are related to the "g" loadings of the test. (SLD)

The relation between Bayley Scale and Stanford-Binet measures in preschool and scholastic achievement at pre-adolescence is examined in the context of an early age intervention. The program sought to normalize the socio-cognitive development of disadvantaged 2-year-olds directly and through a training program for mothers. The follow-up includes a…
