Document Summary
Lecture #2 outline: review multi-store model of memory, basics of visual perception, sensory memory (textbook chapter #3, encoding, duration, capacity, type of code, erasure of sensory memory (sm, summary, multi-store model. Environmental input: get info from environment and comes in from the sensory registers. Gets passed onto the next memory system (short-term store/working memory), where it is temporarily stored, then it gets transferred into long-term store which is the last memory system. A lot of memory is focused on vision. Memory goes through these 3 systems in order. Duration (how long the memory is stored) Type of code(s) (where the memory is stored) Process by which we do some interpretation of the sensation system (understanding at a conscious level); impose some type of coding. Light waves projected onto retina: rods, cones, bipolar cells, ganglion cells. 1st to be stimulated by light waves: neural firing pattern from rod/cones to bipolar cells, and then to ganglion cells.
