PSYCH 100 Lecture Notes - Lecture 21: Long-Term Memory, Iconic Memory, Sensory Memory
Document Summary
Information processing model: compares the human brain to a computer. Involves three processes: encoding, storage, and retrieval: however, our brains are not actually like computers, atkinson-shriffin proposed that there are three areas that the processing of memory goes through: sensory memory, short term memory, and long term memory. Level one of the three stage model: contains raw sensations prior to perception, very large capacity, material is here only briefly. Iconic memory: a brief visual photo of what you are seeing (lasts only a fraction of a second: echoic memory: brief auditory memory of what you are hearing (lasts 3-4 seconds) Level two of three stage model: very limited capacity (7 plus or minus 2 chunks of memory, very limited time (approximately 30 seconds, can keep information here longer with rehearsal, can store more information here with chunking. Long term memory: theoretically unlimited storage, detail level varies.
