PSY 252 Chapter Notes - Chapter 9: Surface Detail, Visual Angle, Stereoscope
Document Summary
Absolute distance: perception of actual distance of object; involves egocentric localization (where our bodies are relative to other objects) Relative distance: involves object-relative localizations (estimates of distances between objects); involved in perception of whether an object is 2d or 3d. 1: visual scene is analyzed by brain in terms of whole objects and surfaces. Information needed to see 3d is already present in retinal image. Impression of depth or distance is immediate upon viewing and needs no further computation. Artificial intelligence: designing machines that behave intelligently". Computational theories: computer programs, or the description of the processes used to create the programs; interpretation of 3d requires complex computations and several analysis stages. Modularity of perception: mind as a distinct set of modules, each with a specific function. Intelligent perception: our perception is much richer and more accurate than what is contained in the visual image alone; information from previous experience, expectations, etc. is involved (constructive theories of perception)
