Document Summary

Retaining info for later use: indication that learning has persisted. Long-term potentiation: making neural connections stronger with repeated stimulation. More times the neurons communicate, the easier it is for neurons to send messages. Receiving neuron: more receptor sites: potentiation -> neural basis for learning. 3 steps to memory: encoding: putting info in, storage: holding on to it, retrieval: getting info out. Human memory is not just one single thing: different memory stores: (sets of neurons that retain info) Three-stage model of memory: sensory memory -> short-term memory -> long-term memory, sensory memory. Stores lots of perceptual info for a sort time (<1 second) Sperling (1960): typically remember 4-5 letters (but report seeing more), like the visual game done in class. Only report one of the rows, specific tone given to tell people which row to remember. Leads to nearly perfect memory, even though tone if after letters.
