1 Chapter 9 Memory I. Stages of Memory A. Processes 1. encoding 2. storage 3. retrieval B. Memory Stores 1. sensory register 2. short-term memory (STM) 3. long-term memory (LTM) C. Sensory memory 1. information in through senses 2. icons – visual memories 3. echoic – auditory memories 4. held until transferred to STM or lost D. Memory organization 1. Semantic – general information (declarative) 2. Episodic – autobiographical; personal 3. Procedural - routines II. Short-term memory 2 A. How things go into STM 1. selective attention – what is attended; what is ignored 2. working memory – STM used to solve problems or for thinking computer analogy 3. interruption and interference 4. Magic # = 7 B. Chunking – recoding information into groups to increase memory capacity C. Rehearsal 1. STM only 20 sec. 2. Improved with repetition 3 III. Long-term memory A. Capacity 1. limitless 2. the more you know, the easier it is to remember related things B. Permanence 1. indefinite time limit 2. most things must be used repeatedly to become permanent 3. permastore – memories that become permanent without much effort C. Constructing memories 1. reconstructive memory a. accuracy b. perception c. closure 2. eyewitness testimony 4 IV. Measuring Memory A. Recognition 1. able to choose correct answer from a field 2. always superior to recall B. Recall – memory without cues 1. serial position effect – items at the beginning and the end of a list are best remembered 2. primacy – items at the beginning of a list remembered 3. recency – items at the end of a list remembered C. Relearning – occurs at a much faster rate than original learning D. Eidetic memory – photographic memory; everything remembered that is seen 5 V. Forgetting A. Ebbinghaus: nonsense syllables B. Encoding failure C. Decay D. Cue-dependent memory 1. cues may aid in recall 2. state-dependent learning a. things learned in ASC best recalled in same state b. depression or other moods E. Interference 1. retroactive interference – new learning interferes with old knowledge Sleep 2. proactive interference – prior learning interferes with learning new information the more similar the info, the more interference learning something wrong old dog – new tricks 6 F. Repression or motivated forgetting G. Flashbulb memory Vivid, but not necessarily accurate VI. Memory Formation A. Amnesia 1. retrograde amnesia – loss of memory of events preceding accident 2. anterograde amnesia – loss of memory of events after accident 3. recent memories more easily disrupted than older memories 7 VII. Improving Memory 1. feedback – knowledge of results 2. recitation – going over info out loud 3. rehearsal – repeating, paraphrasing and summarizing 4. selection – choose only what is most important 5. organization – re-order, chunk, make stories, associate 6. whole vs part learning – study largest meaningful amount of info 7. serial position – study the middle 8. cues – associate with other information a. key words b. method of loci c. imagery d. mnemonics 8 9. overlearning – once you think you know it, study it some more 10. spaced practice – rest in between study sessions 11. sleep – decreases interference 12. review – do not go on to new info 13. strategy for recall
