Document Summary
Psy280 lecture 5: space perception and binocular vision. We see the world 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. But images projected onto the retina do not obey these principles. Internal angles of a triangle always add to 180 degrees, etc. Actual size of stimulation changes as it moves across the retina. To reconstruct a euclidean world from non-euclidian stimulation. We address this challenge by using various cues. Molecular depth cue: a depth cue that is available when the world is viewed with one eye alone. Binocular depth cue: a depth cue that relies on information from both eyes. Used all the different depth cues to fool us. Depth cues that you"re immediately perceiving will be the ones that allow us to make an inference.
