Sex differences in visual information processing following right cerebrovascular accidents.
This study examined whether males and females who had sustained right CVA's but did not show gross asymmetries in processing left- and right-sided visual information would demonstrate visual hemiimperception when tested with more demanding evaluation procedures. Testing involved tasks of reaction time, oral reading and searching for embedded words and figures. Males and females differed in their response patterns for tasks involving searching for embedded target stimuli; specifically, males required greater lengths of time to locate stimuli in left hemispace, while females showed no such pattern of results. This suggests that closer attention must be paid to screening procedures used to detect hemispatial visual imperceptions, particularly among males.
