Document Summary

Neurones in different parts of the brain tend to have different types of receptor fields. One theory proposes that visual areas beyond v1 form 2 parallel processing streams: the lower ventral stream that is specialized for the perception and recognition of objects (color, shapes) and the upper dorsal stream that is specialised for spatial perception. Studies have shown that brain regions in the upper pathway are activated by tasks that require decisions about spatial relationship, whereas regions in the lower pathway are activated by tasks that require identifying objects. D. f. had object agnosia, the inability to recognize objects. A series of laws explain how we perceive features of a visual scene are grouped in organized wholes. Proximity: the closer objects are, the more likely we are to group them and view them as the same object. Good continuation: tendency to interpret intersecting lines as continuous rather than as changing directions radically.
