Recent research in our lab has found a performance dissociation between two task switching paradigms in ML, a patient with reduced short-term memory (STM) capacity. The present study investigates the hypothesis that this dissociation is a result of memory load differences between the two shifting paradigms. We tested this hypothesis by measuring shifting abilities in patients with phonological and semantic short-term memory deficits, as well as age-matched controls under standard and articulatory suppression conditions. The results suggest that task-related memory demands impair the shifting performance of patients with STM deficits, and that phonological (but not semantic) retention contributes to shifting as task requirements increase. application/pdf eng Copyright is held by the author, unless otherwise indicated.
