Document Summary

The five senses and the sensations of them. Visual pathway 2: ganglion cell axons form the optic nerve, optic nerve leaves eye blind spot. Brain fills in the visual field in the blind spot: at optic chiasm half of information crosses to other side. Visual perception: shape and contour: hubel and wiesel (1960s) - recorded from cat visual cortex. Different cortical cells respond maximally to different types of stimuli. Feature detection ability to use minimal patterns to identify objects. Extract key features, fill-in from context and memory. Cells in the lower temporal lobe fire in response to particular faces. Visual perception: motion detection: visual constancy is the tendency to perceive objects as keeping their size, shape, and color, even as retinal image changes. (size constancy, shape constancy, color constancy, brain compares visual frames, as in a movie. Depth perception: 3-dimensional relations: monocular depth cues: Infants between 6 and 14 months hesitate to crawl over the visual cliff.
