ABSTRACT
This article informs that slowed reaction time is a recognized result of impaired central nervous system functioning. However, the specification of the central processes which are impaired has remained elusive. Aged and brain-damaged populations are most likely to have deficits in the response initiation and execution process. If this hypothesis is valid, it would help explain a puzzling finding in studies of reaction time in brain-damaged patients. Such patients have significantly longer simple reaction times and choice reaction times than non-brain-damaged patients, a result which has been classically ascribed to slowed mental processes at the stimulus processing-categorizing level. If brain damage leads to response initiation difficulties, lengthening the inter-stimulus interval should lead to a relatively greater increase in reaction time for such patients than for controls.

Recently, prism adaptation (PA) has been reported as a remarkable approach for USN to reconstruct space...
