Number processing in typical and atypical development

Abstract

Event Abstract Back to Event Number processing in typical and atypical development Susan Rivera1* 1 University of California, Department of Psychology, United States This talk will focus on the neural bases of quantitative reasoning, and what insights have been gained from studying both typical and atypical development. I will present brain imaging data about quantitative reasoning from typically developing children, adolescents and adults as well as from individuals on the fragile X spectrum of disorders. Data will be presented from several fMRI studies which trace the development of a fronto-parietal brain network for quantitative reasoning in typically developing individuals; particularly, increasing functional specialization of the left inferior parietal cortex, and decreasing dependence on memory and attentional resources, for mental arithmetic [1]. Further, data will be presented which supports the hypothesis that impairments in number processing tasks which rely on this fronto-parietal brain network, including mental arithmetic [2] and magnitude estimation, will be sensitive to FMR1 gene expression such that the expected patterns of brain activation follow a dose-sensitive response function.
