We present results from three studies on the development and validation of the Multiple Ability Self-Report Questionnaire (MASQ), a self-report measure comprising items from five cognitive domains; language, visuo-perceptual, verbal memory, visual memory, and attention. In Study 1, we determined the content relevance of the questionnaire items. In Study 2, we assessed the basic psychometric properties (i.e., internal consistency and test-retest reliability) of the MASQ in 118 individuals without neurologic or psychiatric disorder, aged 25 to 88 years. In Study 3 we provide validity data for the MASQ by comparing the ratings of normals to people with unilateral temporal-lobe epilepsy, and examining the relationship of self-report to objective test performance. The potential use of the MASQ to study the neurologic and psychological correlates of accuracy and unawareness in self-appraisal across different cognitive domains and various clinical groups is discussed.

We examined the relationship of age of onset of epilepsy, chronological age at time of operation, and adequacy of preoperative memory performance to pre- to postoperative verbal memory decline. Patients who underwent left (n = 50) or right (n = 51) anterior temporal lobectomy (ATL) were administered tests of verbal episodic (list learning, paragraph recall) and semantic memory (visual naming, vocabulary), both preoperatively and 6 months postoperatively. As a group, left ATL patients showed the classic selective decrease on measures of episodic but not semantic memory. However, examination of episodic memory outcome showed considerable individual variability. Stepwise regression analyses indicated that both later age at onset and older chronologic age were significant and selective predictors of episodic memory decrease for left ATL patients. Adequacy of preoperative memory performance was a nonspecific predictor, associated with decrease in postoperative memory performance for both left and right ATL patients and for multiple types of memory indices. The clinical and theoretical implications are discussed.
