PSYB51H3 Chapter Notes - Chapter 6: Euclidean Geometry, Binocular Summation, Binocular Disparity
Document Summary
Week 6 june 12 th , 2015. 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: names in honor of euclid, the ancient greek geometer of the third century bce, 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 180 degrees, and so forth: the geometry of retinal images of the world is decidedly non-euclidean. Becomes non-euclidean when the 3d world is projected onto the curved, 2d surface of the retina. Probability summation: the increased detection probability based on the statistical advantage of having two (or more) detectors rather than one.
