Face learning and memory: the twins test.
The clinical utility of current face recognition tests has been questioned. To evaluate if a new paradigm may measure this type of memory more accurately, the authors created a novel test to examine face learning (previously uninvestigated) and short- and long-term retention. For this initial investigation of test sensitivity to hemisphere of dysfunction, patients with surgical resection from a temporal lobe and healthy subjects were tested. Recognition was evaluated on 3 trials: after a single exposure, after 4 exposures (for learning), and after a 24-hr delay interval. Patients with a right resection performed significantly worse than healthy controls and patients with left resection. There was no difference between patients with a left resection and controls. Classification of individual patients to side of resection based on test results showed higher sensitivity (82%) than published for other tests and maintained good specificity (79%).
