PS102 Lecture Notes - Lecture 3: Partial Trace, Shelf Life, Metamemory
Document Summary
What is memory: cornerstone of cognition, required for most higher-order functions. Vulnerability of memory: don"t be discouraged, tremendous system, powerful, despite idiosyncrasies. Detect the information (the code) prepare it to be placed in memory. Code can be sound patter, letter sequences, image, tactile cue, smell etc. Storage: encoded information has to be retained, has to be a memory trace. Retrieval: accessing memories, try to remember what was stored, recall no cues, recognition cues. What is the operant term used to denote when something is added to the environment that increases the probability that a behaviour will reoccur: recognition. Positive reinforcement involves adding something to the environment that increases the probability that a behaviour will reoccur. Environment sensory register short term memory long term memory (stm) (ltm) Sensory register memory: holds raw sensory input. Last fractions for a second (1/4 of a second: echoic stress. Remembering when taking notes you are able to hear voice after they have stopped talking: volatile.
