Visuo-spatial working memory is an important source of domain-general vulnerability in the development of arithmetic cognition.
The study of developmental disorders can provide a unique window into the role of domain-general cognitive abilities and neural systems in typical and atypical development. Mathematical disabilities (MD) are characterized by marked difficulty in mathematical cognition in the presence of preserved intelligence and verbal ability. Although studies of MD have most often focused on the role of core...
متن کاملDomain General Sequence Operations Contribute to Pre-SMA Involvement in Visuo-spatial Processing
This study used 3T MRI to elucidate the functional role of supplementary motor area (SMA) in relation to visuo-spatial processing. A localizer task contrasting sequential number subtraction and repetitive button pressing was used to functionally delineate non-motor sequence processing in pre-SMA, and activity in SMA-proper associated with motor sequencing. Patterns of BOLD responses in these re...
متن کاملWhat makes counting count? Verbal and visuo-spatial contributions to typical and atypical number development.
Williams Syndrome (WS) is marked by a relative strength in verbal cognition coupled with a serious impairment in non-verbal cognition. A strong deficit in numerical cognition has been anecdotally reported in this disorder; however, its nature has not been systematically investigated. Here, we tested 14 children with WS (mean age=7 years 2 months), 14 typically developing controls individually m...
متن کاملVisuo-Spatial Attention in ADHD Children: Investigating the Asymmetry
Objectives: The purpose of the present study was comparing visuo-spatial attention between children with Attention Deficit Hyperactivity Disorder-Inattentive (ADHD-I) type and normal children. Methods: In this cross-sectional study fifteen (7-10 years of age) children were classified with ADHD-I type and 15 normal children were matched for age, sex, and IQ. They were selected trough simple r...
متن کاملA Numerical Method for Spatial Diffusion in Age-Structured Populations
We propose a method to approximate numerically the diffusion of an age-structured population in a spatial environment. We integrate separately the age and time variables by finite differences and we discretize the space variable by finite elements. The method is implicit in time and, inside each time step, implicit in age. We provide stability and convergence results and we illustrate our appro...
