Spatial representation [electronic resource] : from gene to mind / Barbara Landau, James E. Hoffman. Landau, Barbara, 1949- Hoffman, James E. Williams syndrome. Cognition disorders. RJ506.W44 L36 2012 618.928 23 Includes bibliographical references and index. Description based on print version record. Despite our impression of a seamless spatial world, mature human spatial knowledge is composed of sub-systems, each specialized. This book uses the case of Williams syndrome to argue for specialization of function in both normal and unusual development. The evidence suggests a speculative hypothesis linking the genetic deficit to changes in the timing of emergence for different sub-systems.
