Document Summary

Memory- retaining info for later use: indication that learning has persisted, 3 steps to memory. Encoding (putting info in) storing retrieval. Long-term potentiation: making neural connections stronger with repeated stimulation, sending neuron: lower threshold, receiving neuron: more receptor sites, potentiation neural basis for learning. Encoding memories: human memory is not just one single thing, different memory stores (sets of neurons that retain info, three stage model of memory (atkinson & shiffrin 1968) Sensory memory short-term memory long-term memory. Sensory memory: lowest level of memory, stores lots of perceptual info for a short time (< 1 sec, exists for all senses, iconic memory: visual form of sm. Sperling (1960) typically remember 4-5 letters but remember seeing more. Study 2: partial report paradigm nearly perfect memory even though tone comes after letters, all letters stored in. Allows cohesive experience of the world based on senses. Blinking without sm- like viewing a slideshow. Speech without sm staccato sounds, not connected words and phrases.
