Presence and Laterality of Brain Damage Predicted from Responses to a Short Aphasia Screening Test

A brief test for aphasia and certain perceprual functions that yields 26 scores per S was administered to a sample of 262 Ss. Without, at present, going into the fine structure of the response patrerns, we wish to be able to state how well this test allows us to predict cerebral damage in any single instance and whether the damage, if any, is diffuse (or bilateral) or principally involves one or the other of the cerebral hemispheres.
