Document Summary
Structuralisms: perceptions are created by combining elements called sensations. Apparent movement: when two stimuli that are in slightly different positions are flashed one after another with the correct timing, movement is perceived between the two stimuli. Illusory contours: contours aren"t actually present in the physical stimulus. Perception of one part of the display is affected by the presence of another part. Difficult to explain a perception that is present and then gone in terms of sensations, since stimulus on retina never changes. The whole differs from the sum of its parts. Perceptual organization: how small elements become grouped into larger objects. Once you perceive a particular grouping it is often difficult not to perceive it this way. Pragnaz: every stimulus pattern is seen in such a way that the resulting structure is as simple as possible. Similarity: similar things appear to be grouped together.
