Document Summary

Figure-ground relations: organizing stimuli into central or foreground figure and a background. We perceive borders and contours when there is a distinct change in colour or brightness. Four gestalt laws: similarity, proximity, closure, and continuity. Recognizing schema: a mental representation or image to compare. Perceptual set: readiness to perceive stimuli in a particular way: perception can be influenced by fear and expectations (perceptual set) Perceptual constancies: our perceptual hypothesis remains the same even though the image on our retina may be different (open vs. closed door) It is a learned skill and requires open spaces to judge distance: problems: many illusions reflect inappropriate scaling (i. e. muller-lyer illusion, problems: retinal size pitted against linear perspective. Muller-lyer illusion: 2 lines of identical lengths, but the direction of arrow creates illusion that one is longer than the other: the illusion only applies to those who live in rectangular world with right angles.
