Document Summary
How low level vision create holistic image as perception. Increasing complexity as we move into higher level cognitive areas. Neural priming: habituation of neurons to stimuli, helps to understand neural substrates of object perception. Takes less effort for neurons to pro(cid:272)ess o(cid:271)je(cid:272)ts it"s per(cid:272)ei(cid:448)ed (cid:271)efore: brain region a. Knows the difference between hammers and screwdrivers: brain region b. Thinks hammers and screwdrivers are the same. What are the dedicated brain regions: lateral occipital complex (loc) Study: low level vs high level activation. What region of the brain is sensitive to shape/form (high level) but not contour (low level) B: same shape different contour, varied what was considered the object and what was the foreground. Does viewing 2 objects with the same shape but different contours, cause adaptation in loc. Most suppression when shape is the same (the high level features) Greater amount of activity in ffa when looking at faces than when looking at objects (or other body parts)
