PSYB51H3 Chapter Notes - Chapter 6: Euclidean Geometry, Binocular Disparity, Depth Perception
Document Summary
Realism: a philosophical position arguing that there is a real world to sense. Positivism: a philosophical position arguing 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. Euclidean: referring to the geometry of the world, so named in honor of eucid, the ancient. In euclidean geometry, parallel lines remain parallel as they are extended in space, objects maintain the same size and shape as they move around in space, the internal angles of a triangle always add to 1800, and so forth. Probability summation: the increased detection probability based on the statistic advantage of having two (or more) detectors rather than one. Binocular summation: the combination (or summation) of signals from each eye in ways that make performance on many tasks better with both eyes than with either eye. Binocular disparity: the differences between the two retinal images of the same scene.
