Document Summary
Grouping by common fate: when items grouped together, they move together. Motion parallax: things closer appear to be moving in opposite direction, things farther away look like they are moving with you. Swinging room experiment: optic flow: wall looks like it is moving towards or away from you. For babies, they tried to readjust their stance to compensate for the optic flow, they fall on their backs or face. Visual capture: when there is a contradiction between vision and other senses, sometimes vision will take over. After things are on the retina, 10% of information goes to the superior colliculus, all fibbers are magno fibres. Superior colliculus involved in the movement of eye muscles. Striate cortex: important for some types of motion perception. Complex and hyper-complex cells that respond differently depending on effects of early deprivation: kittens placed into strobe environment, that is all that they see. They will have problems with their motion perception.
