Document Summary

Lecture 1 of chapter 6- types of memory. What is memory: ability to store and use information, also the store of what has been learned and remembered, three processes: Encoding/consolidation= translating into neural code, translating external stimuli into neurons and action potentials. Three-stage model of memory: in this model, memory has three major components, sensory memory, which briefly (from a few minutes to a couple of seconds) holds incoming. If you don"t pay attention to the stimuli, it will be sensory memory: working (short-term) memory, which processes certain information received from sensory memory and information retrieved from long-term memory. Lasts 12-30 seconds, capacity of 7 +/- 2 chucks of information. Once you start to pay attention to the stimuli, then it will become short-term memory. Phone numbers are made of 7 numbers because the short term memory can hold 7 chucks of information. Unrehearsed information is lost: long-term memory, which stores information for longer periods of time.
