Document Summary

Memory: capacity to acquire and retain skills and knowledge. He would teach the mice to run a maze. Then take out a part of the mice"s brain. Then found that the mice did not do as well. He found that we use all parts of our brain that contribute to how we process memory. Memories change over time because we unpack and repack a memory every time. Tetris vs. ptsd: memories over time. Sensory memory: perceptual traces, 1/3 of a second (how long we long we retain something) Short-term (working) memory: 7+/-2 (how much stuff we can hold, chunking. Long-term memory: primacy and recency, repeated, deep, and useful info. Transience, blocking, and absentmindedness: memory distortion. Bias: tend to recall past beliefs as consistent with current beliefs. Can be distorted just like other memories. False information can distort or implant memories.
