Document Summary
Left limbic mtl damage- verbal memory impairment eg. recollecting words, remember names. R limbic mtl damage- non-verbal mem impairment eg. abstract designs, spatial tasks, music, faces. Impairment- seach hemisphere is dominant for certain material but ht eother hem is still capable for some processing (lamguage, spatial processing) Dr milner and her graduate students invertigated unilateral patients as well. Philip corsi- recurring digit sequence test (originally from hebb) our working memory (wm) span is 7 items +/- 2 usually verbal span is a bit larger than non-verbal span. Hebb found if one sequence @ span+1 was repeated often, endergrad students could learn it. (i. e. you know your bank card number cuz you repeat so often) So corsi tested patien w unilateral damage to limbic mtls using digit seq of span+1. This controlled for level of di culty one of the sequences would repeat.
