PSYC 2700 Lecture Notes - Arthropod Eye, Backward Masking, White Noise
Document Summary
Psychology 2700: multi-store model of memory: the idea that info flows through our system. These memory stores can be differentiated based on i. ii. iii. iv. Type of code: basics of visual perception. Light waves project onto retina (p. 77) i. ii. iii. iv. v. Neural firing pattern from rod/cones to bipolar cells, then to ganglion cells. Axons of ganglion cells form bundle called optic nerve vi. Nerve projects back to send neural message to visual cortex in occipital lobe. Cones are for color vision; rods are for black and white. Compression: peripheral vision, because we don"t need detail. Only fraction of light waves reaches the retina. Series of fixation-saccade cycles: twitches moving our eyes around in a certain way, rapid. Eyes pause to foveate and take in info. Fovea is where highest resolution in eye is: sensory memory: neural activation in the retina is brief and terminates with external stimulation. The perception of the event persists after stimulus is terminated.
