PSYC 309 Lecture Notes - Lecture 7: Paul Kay, Visual Impairment, Semantic Dementia
Document Summary
Verbal task + colour matching = slowdown. Lack of spatial language is not a handicap in solving spatial problems. Language helps use learn novel categories; unusual ability to operate on abstract plane: after category has been learned, can distort memory of specific objects. Getting between us and the rest of nonabstract world. Results: both showed canonicality effect on horizontal axis (earlier = left; consistent w/ writing): only mandarin - canonicality effect on vertical axis (responded faster when earlier. Anomia a problem assessing the names of words: handsaw won"t be able to say the word saw, describes detail, but struggles to say it. Where"s the visual impairment of representation in associative agnosia: same kind of problem, associative impairment in visual representation; anomia impairment in assessing representation of name. Semantic dementia a problem that includes loss of word meaning: start to talk, use words, but don"t have meaning tied to words.
