  1. Myers EXPLORING PSYCHOLOGY (6th Edition in Modules) Module 22 Forgetting, Memory Construction, and Improving Memory James A. McCubbin, PhD Clemson University Worth Publishers

  2. Attention External events Sensory memory Short- term memory Long- term memory Encoding Encoding Encoding failure leads to forgetting Forgetting • Forgetting as encoding failure • Information never enters long-term memory

  3. Percentage of list retained when relearning 60 50 40 30 20 10 0 1 2 3 4 5 10 15 20 25 30 Time in days since learning list Forgetting • Ebbinghaus forgetting curve over 30 days-- initially rapid, then levels off with time

  4. 100% 90 80 70 60 50 40 30 20 10 0 Percentage of original vocabulary retained Retention drops, then levels off 1 3 5 9½ 14½ 25 35½ 49½ Time in years after completion of Spanish course Forgetting • The forgetting curve for Spanish learned in school

  5. Attention Encoding External events Sensory memory Short-term memory Long-term memory Encoding Retrieval Retrieval failure leads to forgetting Retrieval • Forgetting can result from failure to retrieve information from long-term memory

  6. Forgetting as Interference • Learning some items may disrupt retrieval of other information • Proactive (forward acting) Interference • disruptive effect of prior learning on recall of new information • Retroactive (backwards acting) Interference • disruptive effect of new learning on recall of old information

  7. Forgetting as Interference

  8. 90% 80 70 60 50 40 30 20 10 0 Without interfering events, recall is better Percentage of syllables recalled After sleep After remaining awake 1 2 3 4 5 6 7 8 Hours elapsed after learning syllables Forgetting • Retroactive Interference

  9. Forgetting • Forgetting can occur at any memory stage • As we process information, we filter, alter, or lose much of it

  10. Forgetting: Interference • Motivated Forgetting • people unknowingly revise memories • Repression • defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories

  11. Memory Construction • We filter information and fill in missing pieces • Misinformation Effect • incorporating misleading information into one's memory of an event • Source Amnesia • attributing to the wrong source an event that we experienced, heard about, read about, or imagined (misattribution)

  12. Depiction of actual accident Leading question: “About how fast were the cars going when they smashed into each other?” Memory construction Memory Construction • Eyewitnesses reconstruct memories when questioned

  13. Memory Construction • Most people can agree on the following: • Injustice happens • Incest happens • Forgetting happens • Recovered memories are commonplace • Memories recovered under hypnosis or drugs are especially unreliable • Memories of things happening before age 3 are unreliable • Memories, whether false or real, are upsetting

  14. Improve Your Memory • Study repeatedly to boost recall • Spend more time rehearsing or actively thinking about the material • Make material personally meaningful • Use mnemonic devices • associate with peg words--something already stored • make up story • chunk--acronyms

  15. Improve Your Memory • Activate retrieval cues--mentally recreate situation and mood • Recall events while they are fresh-- before you encounter misinformation • Minimize interference • Test your own knowledge • rehearse • determine what you do not yet know
