Document Summary
Psy280 chapter 6: space perception and binocular vision. Realism: philosophical position arguing that there is a real world to sense. Positivism : argues that all we really have to go on is the evidence of the senses, so the world might be nothing more than an elaborate hallucination. Enable you to see more of the world. Overlapping, frontal, binocular visual fields give predator animals such as humans a better chance to spot small fast=moving objects in front of them that might provide dinner. Probability summation: increased detection probability based on the statistical advantage of having two or more detectors rather than one. Binocular summation: combination of signals from both eyes in ways that make performance on many tasks better than with either eye alone. Binocular disparity: difference between the two retinal images of the same scene. Disparity is the basis for stereopsis, a vivid perception of the three- dimensionality of the world that is not available with monocular vision.
