Aim: Although approximately 40% of children with neurofibromatosis type 1 (NF1) meet diagnostic criteria for attention-deficit-hyperactivity disorder (ADHD), the impact of ADHD on the executive functioning of children with NF1 is not understood. We investigated whether spatial working memory and response inhibition are impaired in children with…

This article outlines a model of the structure and the dynamics of gender cognition in childhood. The model incorporates 3 hypotheses featured in different contemporary theories of childhood gender cognition and unites them under a single theoretical framework. Adapted from Greenwald et al. (2002), the model distinguishes three constructs: gender…

Advances in neuroscience during the past century have yielded important insights into mental functioning, but their implications for the field of education have remained largely unexplored. In a bold attempt to bridge this gap, Immordino-Yang presents findings from 2 boys, Nico and Brooke, each of whom lost half of his brain. The remarkable…

Sex differences in the latent general and broad cognitive abilities underlying the Woodcock-Johnson Tests of Cognitive Abilities were investigated for children, youth, and adults ages 6 through 59. A developmental, multiple indicator-multiple cause, structural equation model was used to investigate sex differences in latent cognitive abilities as…

In two experiments, the principles of cognitive load theory were applied to the design of alternatives to conventional music instruction hypothesised to facilitate learning. Experiment 1 demonstrated that spatial integration of visual text and musical notation, and dual-modal delivery of auditory text and musical notation, were superior to the…

This article shares the story of Alex, a gifted child. Alex is clearly gifted when observed through one lens and yet obviously lagging when viewed from a different angle. He knew his letters at 20 months, but did not learn to tie his shoes until the middle of second grade. He taught himself to read just before his third birthday, but in third…

Based on stimulating findings suggesting that prenatal levels of steroids may influence cognitive functions, a study with N=40 healthy volunteers of both sexes was conducted. Prenatal levels of testosterone (T) were estimated by use of the second-to-fourth digit ratio (2D:4D) which is supposed to be controlled by the same genes involved in…

Argues that knowledge from studies of individuals with sex chromosome abnormalities can further understanding of aspects of normal human development. Studies of XO girls, XXY boys, XXX girls, and males with a fragile X chromosome are summarized to demonstrate how results contribute to knowledge about normal cognitive development and about…

The concern here is with kinds of cognitive structures individuals use in making major life choices upon which subsequent development depends. The system conceptualized for describing these psychological processes, pictures each choice domain (such as occupations) as a set of concentric squares. The outermost square deals with total knowledge of…

The hypothesis that children with specific language impairments (SLI) have a hierarchical planning deficit was evaluated with 15 boys (ages 5 to 7) with SLI and 15 controls, who built 4 hierarchical structures varying in complexity. Results did not support the idea that a central hierarchical planning mechanism underlies language and nonlanguage…

Examined were the relative effects of a number of variables, but particularly sex and field-dependence, on performance of secondary school students on Piagetian measures of formal thought. It was hypothesized that males will receive significantly higher mean scores than females on all measures; that field-independent subjects will receive…

The authors are emmersed in a comprehensive review of the literature on intellectual sex differences. This paper consists of the first progress report and the tentative hypotheses of the work completed so far. Discussion is initially concerned with verbal and spatial abilities. It is concluded that girls learn language earlier, and may continue to…

Literature suggests that females have lower initial expectancies for success than males. The antecedents of this difference are considered: (a) by examining when expectancy differences develop, and, (b) by examining cognitive factors which may underlie these differential expectancies. (Author/AM)
