PSYB57H3 Chapter Notes - Chapter 4: Principles Of Grouping, Edward B. Titchener, Extrastriate Cortex
Document Summary
Extrastriate cortex: a set of visual areas (v2, v3, etc. ) that lie just outside the primary visual cortex. Where pathway (focused on later in course: heads up into the parietal lobe, processes information relating to the location of objects in space and the actions required to interact with them. What pathway: heads down into the temporal lobe, object recognition. Maintains close connections with parts of the brain involved in memory formation hippocampus. Some of the cells have very specific tastes. Agnosia (cid:862)psy(cid:272)hi(cid:272) (cid:271)li(cid:374)d(cid:374)ess(cid:863: a failure to recognize objects in spite of the ability to see them, can be quite specific. Seems to be selectively responsive to one specific object. Processed holistically unlike other objects which may be analyzed in parts. Must be possible to do some rough object recognition on the basis of the first wave of activity as it moves from retina to striate cortex to extrastriate cortex and beyond: feed-forward process.
