Document Summary
Explain the heuristics that are involved in perception. What are three questions that the brain must answer? o explain the principles the brain uses to answer each question o give examples of each principle. Your slow brain answers questions instantly and accurately. The proximal stimulus does not contain enough information on its own. So what does the brain do? o massive reliance on heuristics o simultaneous expectations and knowledge) processes. Bottom-up (data driven) processes o feature detectors o figure-ground perception o similarity, proximity o good continuation. Top down (conceptually driven) processes o priming and context effects. Gestalt psychologists also thought that an important part of our perception was the organization of a scene into its . Relative size- smaller image is more distant. Relative clarity- hazy object seen as more distant. Relative height- higher object seen as more distant. Relative motion- closer objects seem to move faster. Linear perspective- parallel lines converge with distance.
