Executive functions (EF) are domain-general cognitive skills that predict foundational academic skills such as literacy and numeracy. However, less is known about the relation between EFs and science achievement. The nature of this relation might be explained by the theory of mutualism, which states that development is the result of complex and…

Hala, Brown, McKay, and San Juan (2013) found that children as young as 2.5 years of age demonstrated high levels of accuracy when asked to recall whether they or the experimenter had carried out a particular action. In the research reported here, we examined the relation of early-emerging source monitoring to executive function abilities.…

Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

An enduring challenge in visual-spatial research has been to identify the factors contributing to individual differences in ability. This research investigated the overall, verbal, and nonverbal visual-spatial ability of 61 (34 boys) three- to five-year-olds (M[subscript age] = 57.3 months; SD = 7.9) and the following factors known to be related…

The study of executive function (EF) has become increasingly popular in multiple areas of research. A wealth of evidence has supported the value of EF in shaping notable outcomes across typical and atypical development; however, little evidence has supported the cognitive contributors to early EF development. The current study used data from a…

Most of the individual difference variance in the population is found "within" families, yet studying the processes causing this variation is difficult due to confounds between genetic and nongenetic influences. Quasi-experiments can be used to test hypotheses regarding environment exposure (e.g., timing, duration) while controlling for…

Child prodigies are unusual for their early and exceptional adoption of what are traditionally thought of as adult abilities. As part of an effort to better understand the underpinnings of these extraordinary individuals' talent, the researcher examined the cognitive and developmental profiles of eight child prodigies by taking their developmental…

In autism spectrum disorders, results of cognitive testing inform clinical care, theories of neurodevelopment, and research design. The Wechsler Intelligence Scale for Children and the Stanford-Binet are commonly used in autism spectrum disorder evaluations and scores from these tests have been shown to be highly correlated in typically developing…

Aim: There is a lack of investigation into the functional developmental profile of children with Down syndrome. On the basis of current international health paradigms, the purpose of this study was to assess the developmental profile of these children. Method: Sixty children (33 males, 27 females) with Down syndrome (age range 6-16y; mean age 9y…

Forty-five gifted children, ages 11-17, were tested with the Stanford-Binet Intelligence Scale and the Woodcock-Johnson Tests of Achievement. Results indicated 18 of 20 correlations between the area and composite scores were significant. The Stanford-Binet Short-Term Memory standard age score mean was lower than other scores' means.

This study investigates the validity of the Stanford Binet Intelligence Scale-Fourth Edition (S-B:4) for use with students with learning disabilities. It compares the performance of 18 elementary-age students on the S-B:4 and the Kaufman Assessment Battery for Children (K-ABC). The subjects were identified by their school as having learning…

The Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet: Fourth Edition (S-B:FE) were administered in counterbalanced order to a sample of 20 middle-class preschool children (11 males and 9 females) attending the Early Childhood Preschool Center located in a suburban area of a large midwestern city. Subjects' mean age was 4…

The Stanford-Binet: Fourth Edition and Kaufman Assessment Battery for Children were administered in counterbalanced order followed by the Cognitive Domain of the Battelle Developmental Inventory to a sample of 30 nonhandicapped, preschool children (13 males and 17 females). Correlations (corrected for restriction in range) among the three…
