Document Summary

Apperceptive agnosia: able to see object"s shape and colour and position but unable to put elements together: d. f. : could not see and assemble various elements that she sees: cannot copy drawing, but can draw the object from memory, lesion in lateral occipital complex, activated when neurologically healthy people are recognizing objects. Associative agnosia: can see but unable to link what they see to their visual knowledge. Integrative agnosia: impaired in tasks that require them to judge how features are bound together to form complex objects: damage in parietal cortex, apperceptive agnosia + associative agnosia. Factors influencing recognition: tachistoscope: device to present stimuli for controlled amounts of time, now use computers, and called tachistoscopic presentations, mask: serves to interrupt continued processing, factors. Letter strings that are not english words but look like english strings and are easy to pronounce still produce effect.
