Document Summary

Nisbett (2001) found that easterners are more likely to be influenced by the background of a figure, whereas westerners will more likely extract the figure from its background. Memories of a particular shape can inform shape processing. Bottom-up: a hierarchical model of pattern recognition in which data are relayed from one processing level to the next, always moving to a higher level of processing. Top-down: a hierarchical model of pattern recognition in which information at higher levels of processing can also influence lower, earlier levels in the process, which is why context affects perception. Face perception reveals more about the person than anything else. Certain brain regions are dedicated only to perceiving them. A region of the fusiform gyrus, in the right hemisphere, may be responsible for perceiving faces. This brain area responds strongly to upright faces. Other brain areas are sensitive to changes in faces, such as facial expression and gaze direction.
