摘要

The neural mechanisms underlying visuomotor transformation are examined based on deficits in tracing and copying, as well as functional neuroimaging studies. The developmental process of copying and tracing, as well as lesion studies with adults showing disability in drawing, are reviewed, then two experiments are introduced. In Experiment 1, a behavioral analysis of copying and tracing by individuals with Williams Syndrome (WS) was presented. In Experiment 2, the brain activity involved in copying and tracing was measured in normal adults using functional magnetic resonance imaging. Based on these findings, we propose a model of visuomotor transformation to explain the neural basis of tracing and copying, as well as to provide a possible neural mechanism underlying the copying deficits and closing-in phenomenon observed in WS.
