Function of the Basal Ganglia essays The effect of perceptual sets on the interpretation of ambiguous figures Many studies have been performed to examine the effects which perceptual sets have on the interpretation of images. The purpose of this study was to examine the effect of perceptual sets on participant's interpretation of an ambiguous figure, and to see if perceptual sets were induced upon participant's viewing of a second ambiguous figure. The study involved 28 participants who were asked to view a series of 4 images followed by an ambiguous figure. This was repeated with a set of four different images. The results were consistent with those of Power (1983), in that perceptual sets effect the way in which people interpret ambiguous figures. The study also found that perceptual sets did not play a role in the interpretation of the ambiguous figure for the second time. Many studies have been performed to show that past expectancies and experience effect the way which individuals view and attend to features in the visual field. This phenomenon has been examined in regard to brain activity and attentive processing to explore the effects which experience and expectations have on people when they interpret The visual cortex consists of 2 main areas, the primary visual cortex (V1) and the s secondary visual cortex (V2) . Cells within the V1 and V2 are horizontally connected, and integrate information from a large part of the cortex. These cells are clustered into specific groups, based on their functional properties (Kalat, 2001). Furthermore, these clusters can often integrate information based on what is being focused on in the visual field. This biological explanation demonstrates the concept that the cells within the visual cortex interact and combine information to interpret an image in the visual field. For this process to occur, people must be able to distinguish an image from its background. A theory by Treisma...
