Performance on WISC-III and WAIS-R NI vocabulary subtests assessed with event-related brain potentials: an innovative method of assessment.
Assessment of intellectual functions is essential for rehabilitative interventions with traumatic brain injury and stroke patients. However, many of these patients are difficult or impossible to assess because of aphasia and physical disabilities that prevent their performance on traditionally administered tests of mental functioning. We present normative evidence obtained from healthy individuals for the efficacy of a new method of assessing such patients using standardized and validated tests formatted for computer presentation and using direct measures of brain activity (event-related brain potentials, ERP) as the measurable response instead of verbal or motor behavior.
