Document Summary
Identifying key features of tools and objects for use. Understanding tools, objects, and gestures different types of conceptual knowledge are dissociable. It appears that different types of conceptual knowledge associated with action are dissociable from each other as demonstrated in the next slides. Buxbaum and saffran (2002) investigated function and manipulation knowledge in apraxic and non-apraxic patients with lhd (aside, px were apraxic to gestural tests including tests of pantomime) Function knowledge which two items are most similar in function (e. g. , stapler, cellophane tape, pen) Manipulation knowledge which two items are most similar in manner of manipulation (e. g. , piano, typewriter, stove) Results apraxic patients were more impaired in manipulation test, than function test. Kellenbach et al. (2003) used pet to investigate brain activation associated with function and manipulation judgments. Results showed that when participants made conceptual judgments about function, there was activation of a left network consisting of the ventral premotor cortex and the posterior middle temporal gyrus.
