Experienced teachers have long asserted that children blind from retinoblastoma (Rb), a rare cancer of the eye, are of above average intelligence. To test this hypothesis, standardized verbal intelligence tests were administered to a sample of 85 children and adults, all diagnosed with the early infancy form of this condition. For 42 of the Rb…

In this study, we tested the outcomes of access to a Response to Intervention (RtI) model in kindergarten or in first grade on end-of-Grade-2 reading achievement and placement in special education. Across five schools, 214 students who began having access to Tier 2 intervention in kindergarten or first grade were compared in Grades 1 and 2 with…

In this article, I describe studies conducted over 25 years with secondary and post-secondary L2 learners in the United States. The evidence from these studies shows that there are important connections between students' early L1 skills and their L2 aptitude and L2 proficiency and that individual differences in students' L1 skills in elementary…

Background: Shayer, Ginsburg, and Coe (2007) showed that children leaving primary school in Y6 entered secondary school with much lower levels of understanding of the physical conservations than in 1976. It seemed desirable to investigate cognitive development in the first three years of secondary education. Aims: By using two Piagetian tests of…

We tested the effects of teaching reading skills through U.S. history content for 38 eighth-grade poor readers whose reading ability ranged from second-to fourth-grade levels. Half of the students received special education services, and half of the students were English language learners. Students were taught to decode multisyllabic words, learn…

Inspired by a previous study of Korean deaf and hard of hearing adolescents, the researchers conducted a priming task of living-nonliving categorization with a sample of Chinese deaf and hard of hearing adolescents. The sample in this study had significantly lower accuracy levels for the thematically related items than for the taxonomically…

Aim: Individuals with congenital insensitivity to pain with anhidrosis (CIPA) are reported to have mental retardation but to our knowledge no detailed study on the subject has ever been published. The present study assessed and documented cognitive and adaptive behaviour among Arab Bedouin children with CIPA. Methods: Twenty-three Arab Bedouin…

Aim: The aim of this study was to assess cognitive function at the age of 19 years in individuals of very low birthweight (VLBW; less than or equal to 1500g) and in term-born comparison individuals. Method: In this hospital-based follow-up study, 55 VLBW participants (30 males, 25 females; mean birthweight 1217g, SD 233g; mean gestational age…

The Wechsler Intelligence Scale for Children--Fourth Edition (WISC-IV; D. Wechsler, 2003a) is often utilized to assess children with traumatic brain injury (TBI), although little information is available regarding its psychometric properties in these children. The current study examined WISC-IV performance in a sample of 61 children with TBI. As…

While early childhood education has received increasing attention in the developing world in recent years, relatively little evidence is available from sub-Saharan Africa on its effects on child development and subsequent school enrolment. We use a prospective case-control design to evaluate the developmental impact of a community-based early…

Learning Disabilities (LDs) affect a significant number of students in elementary and secondary school. In order for these students, along with parents and teachers, to understand the nature of their specific difficulties, and have equal opportunity in academic settings, a comprehensive psychological report containing properly informed…

Two groups of adolescents (N = 114), 61 identified-gifted adolescents (M = 22, F = 39) and 51 vocational school adolescents (M = 27, F = 26), were compared on the Overexcitability Questionnaire. Each of the five Overexcitability (OE) scores--Psychomotor, Sensual, Imaginational, Intellectual, and Emotional--was subjected to a two-way ANOVA by…

The concepts of intelligence and methods to assess it constitute important contributions to psychology and have had a profound impact on school psychology practice. While the perspectives and practices of North American and European psychologists toward the construct and assessment of intelligence generally are well known, the views held by…

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures…

This is an executive summary of a longer report: "AISD Prekindergarten Program Longitudinal Summary Report Issue 2: Half-Day versus Full-Day Programs." In the Austin Independent School District, full-day pre-K students from the 2001-2002 cohort were more likely to pass the 2010 Texas state assessment for 7th-grade reading TAKS than were…
