Abstract

We asked 28 registered nurses with varying degrees of experience in working with neurological and neurosurgical patients to fake results on 10 neuropsychological tests in such a way as to be congruent with a history of trauma to the left fronto-temporal cortex. We compared these data to those obtained from 21 patients who had been referred with verified cerebral injury and who had a diagnosis of left fronto-temporal dysfunction. The overall hit rate of classification for the two groups was 85.7% and 89.8%, depending on the way in which test scores were combined. Results showed that a knowledgeable group of informed fakers had great difficulty reproducing the test performance of individuals with left fronto-temporal impairment.
