Orientation testing and responses of brain-injured subjects

This study examined the responses of three groups of brain-injured subjects to the Ross Information Processing Assessment (RIPA) to demonstrate any effects of lesion laterality or type on spoken response performance. All groups displayed a moderate to severe degree of disorientation. Significant correlations among subtest scores were more numerous for the left hemisphere CVA patients. Results suggested that orientation task performance may be an artifact of spoken language function and indicated caution in interpreting patients' orientation scores from assessment instruments which require verbal responses.
