Despite some gains, women continue to be underrepresented in many science, technology, engineering, and math (STEM) fields. Using a national longitudinal dataset of 690 participants born in 1991, we tested whether spatial skills, measured in middle childhood, would help explain this gender gap. We modeled the relation between 4th-grade spatial…

Background: Developmental research provides considerable evidence of a strong relationship between verbal and visuospatial working memory (WM) and mathematics ability across age groups. However, little is known about how components of WM (i.e., short-term storage, processing speed, the central executive) might relate to mathematics sub-categories…

Borderline intellectual functioning is a neurodevelopmental condition characterized by an intelligence quotient (IQ) in the range of 70-85. The present study aimed to investigate the mathematical abilities and the working memory of students with borderline intellectual functioning (BIF). The sample group included 10 year-old students with BIF (n =…

Working memory (WM) measures are routinely integrated into comprehensive diagnostic evaluations. However, there is little research regarding the underlying components of WM and their developmental trajectories. The current study examined the developmental trajectories of distinct WM components in a sample of 303 individuals ages 6 through…

Proficient use of spatial terms such as "under," "to the left of" or "in front of" is a central component of daily communication and is important in the development of language and spatial cognition. Here we examine spatial language abilities in intellectually high-functioning individuals with autism spectrum…

Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. The present research tested whether "relational…

Verbal--spatial discrepancies are common in healthy individuals and in those with neurodevelopmental disorders associated with cognitive control deficits including: Autism Spectrum Disorder, Non-Verbal Learning Disability, Fragile X, 22q11 deletion, and Turner Syndrome. Previous data from healthy individuals suggest that the magnitude of the…

Background: School attainment tests and Cognitive Abilities Tests are used in the United Kingdom to set targets for educational outcome. Whilst these are good predictors, they depend not only on basic ability but also on learnt knowledge and skills, such as reading. Method and Aims: VESPARCH is an online group test of verbal and spatial reasoning,…

Background: Conclusive evidence supports the importance of fundamental movement skills (FMS) proficiency in promoting physical activity and countering obesity. In children with Down Syndrome (DS), FMS development is delayed, which has been suggested to be associated with balance deficits. This study therefore examined the relationship between FMS…

The ability to recognize temporal patterns and position events in time emerges during the preschool years and is refined in middle childhood. This study explored individual differences in temporal cognition in relation to verbal and nonverbal abilities. Children (30 boys, 32 girls; M[subscript age] = 8;2, age range = 6;0-10;8) completed 3…

We examined the relation of parental socioeconomic status (SES) to the neural bases of subtraction in school-age children (9- to 12-year-olds). We independently localized brain regions subserving verbal versus visuo-spatial representations to determine whether the parental SES-related differences in children's reliance on these neural…

The Wechsler Intelligence Scale for Children, Fifth Edition: Canadian (WISC-V[superscript CDN]; Wechsler, 2014) is published by Pearson Canada Assessment. The WISC-V[superscript CDN] is a norm-referenced, individually administered intelligence battery that provides a comprehensive diagnostic profile of the cognitive strengths and weaknesses of…

Purpose: The current study examined whether children with autism spectrum disorder (ASD), in comparison with typically developing children, perceive and produce gestures to identify nonpresent objects (i.e., referent-identifying gestures), which is crucial for communicating ideas in a discourse. Method: An experimenter described the uses of…

This study investigates whether age-related changes in the structure of 5 complex working memory (WM) tasks (a) reflect a general or domain specific system, (b) follows a similar trajectory across different age spans, and (c) contribute domain general or domain specific resources to achievement measures. The study parsed the sample (N = 2,471)…

Research Findings: The contribution of 3 executive function skills (shifting, inhibitory control, and working memory) and their relation to early mathematical skills was investigated with preschoolers attending 6 Head Start centers. Ninety-two children ranging in age from 3 years, 1 month, to 4 years, 11 months, who were native English or Spanish…
