Summary: The relationships among self‐report of memory, actual memory performance on objective tasks, and lesion laterality were examined in this longitudinal study. Right‐handed adults (n = 47) with medically intractable seizures were assessed both preoperatively and 1 year after a left or right temporal lobectomy. Memory complaints remained stable or diminished postoperatively, whereas performance on material‐specific memory tasks declined. Regression analyses showed that dosage of medications, seizure frequency and self‐reported depression were predictive of postoperative memory complaints, although size of resection and age were not. Together, these data suggest that many patients have a positive though mistaken impression that their memory functions improved after temporal lobectomy, an impression influenced by their positive surgical outcomes. Memory complaints did not predict laterality of the lesion. Sex‐laterality interactions were evident for both subjective and objective memory measures.
