Case report: A global sequential processing disorder following head injury: A possible role for the right hemisphere in serial order behavior

Abstract

A single case is presented in which, following traumatic injury primarily involving the right cerebral hemisphere, the subject presented with severe deficits in his ability to produce overlearned and newly presented arbitrary verbal and spatial sequences. In contrast, his ability to produce logically or physically constrained sequences remained relatively intact. This case is considered as evidence for the existence of a higher order sequential processing mechanism which, in some people, may be important in both verbal and visuospatial sequential information processing.
