This article presents an attempt to use an electrodermal apparatus in order to establish the identity of an amnesic patient. By employing items of high personal relevance it proved possible to detect some useful information from the patient, although she claimed to be unaware of the information sought. There was a marked increase in electrodermal responsivity to items of personal relevance as the patient admitted more awareness of her past history, suggesting that detect-ability may improve with heightened conscious awareness.
