  1. Information Processing Module 20

  2. What is Memory? Process of encoding, storage, and retrieval. Learning that persists over time. Encoding • Get info in Storage • Retain the info Retrieval • Getting the information out

  3. In-Class Activity—A Look Into Memory Take out a sheet of paper Write down, in order, all responses that come to mind Ready?

  4. What are the names of the seven dwarfs in the story of Snow White? Don’t ask a friend!

  5. What are the names of the seven dwarfs in the story of Snow White? Difficult? Why? • Never learned the names (encoding) • Length of time (storage) • Distractions (retrieval)

  6. What if you had a list to choose from? Grouchy Gabby Fearful Sleepy Smiley Jumpy Hopeful Shy Droopy Dopey Sniffy Wishful Puffy Dumpy Sneezy Lazy Pop Grumpy Bashful Cheerful Teach Shorty Nifty Happy Doc Wheezy Stubby

  7. What are the names of the seven dwarfs in the story of Snow White? The names… • Sleepy, Dopey, Grumpy, Sneezy, Happy, Doc & Bashful Get more names correct with list? Why? • Recall vs. Recognition

  8. What are the names of the seven dwarfs in the Disney movie Snow White? Feel like you knew a name but couldn’t recall it? Why? • Tip of the tongue phenomenon • Retrieval failure

  9. In-Class Activity – Part 2… Turn your paper over or fold in half Write down the names of the seven dwarfs Easier than before? • Short term memory vs. long term memory

  10. Encoding: Getting Information In Automatic Processing • Time • Space • Frequency • Well-learned material Effortful Processing

  11. Encoding: Getting Information In Effortful Processing Ebbinghaus: Rehearsal & Overlearning

  12. How do we encode? Serial Position Effect

  13. Howdo we encode? Spacing Effect Distributed vs. Cramming Rehearsal Primacy & Recency

  14. What do we encode? Meaningful Information • Personally meaningful • Related to previously learned info Encoded Images • Mental “pictures” • Mnemonics • Kids Please Close Our Front Gate Slowly

  15. What do we encode? OrganizedInformation • Chunking • ROY G BIV • Phone numbers… 867-5309 • Hierarchies

  16. This might help you study…

  17. Let’s test your encoding!iclicker question According to the serial position effect, when recalling a list of words you should have the greatest difficulty remembering those: A) at the beginning of the list B) at the end of the list C) in the middle of the list D) at the beginning and the end of the list

  18. iclicker question You are most likely to automatically encode information about: A) Politicians names B) New phone numbers C) What you did before and after you ate breakfast D) What we learn today

  19. Storage: Retaining the Information Working/ Short-term Memory Sensory Memory Long-term Memory Encoding Events Encoding Retrieval Retrieval

  20. Storage- Retaining the Information Sensory Memory Fleeting representation unless we attend Lasts for ~ second Iconic & Echoic

  21. Storage Working/Short-Term Memory 20 secs – couple minutes “Hold” a limited amount of info (7 +/- 2) No active processing = no short-term memories disappear

  22. Storage Long-Term Memory Info stored; can be retrieved Lasts indefinitely Can hold billions of pieces of info

  23. Storage- How do we do it? Synaptic Changes Pathway of neural activation creates a stored memory Path reinforced with use

  24. Storage Stress Hormones Heightened emotions = stronger memories Boosts activity in memory-forming brain areas More replay= stronger connections Can we take a pill for this?

  25. Storage Implicit Memory • Memory for procedures & skill acquisition • Ex: Driving a car • Cerebellum Explicit Memory • Memory for facts & experiences • Ex: Who was your first kiss? • Hippocampus-temporary storage site • Cortex

  26. Retrieval- Getting Information Out 3 Retrieval Types • Recall: generate information • Recognition: identify items • Relearning: learn material for a second time

  27. Retrieval Retrieval Cues: Anchor points used to access the info later

  28. Retrieval Context Effects Remember better if cues present at encoding are present at retrieval

  29. Retrieval Mood-Congruent Memory Recall experiences consistent with current mood

  30. Déjà Vu Familiar situation can trigger feelings of “I’ve been here before”

  31. Another Activity… 2 volunteers 1 with musical knowledge (majors, private lessons) 1 with little musical knowledge

  32. Retrieval & Expertise Expertise Development Central concepts become increasingly elaborated, organized & interconnected

  33. Iclicker Question When 80-year-old Ida looked at her old wedding pictures, she was flooded with vivid memories of the early years of her marriage, which she had not thought about in decades. The pictures served as powerful: A) Encoding cues B) Iconic memories C) Implicit memories D) Retrieval cues

  34. Iclicker Question Memory of facts is to ________ as memory of skills is to ________. A) Brainstem; Hippocampus B) Explicit Memory; Implicit Memory C) Automatic Processing; Effortful Processing D) Short-term Memory; Long-term Memory

  35. So could our memory ever be too good? The women who can’t forget… http://www.youtube.com/watch?v=SoxsMMV538U&feature=related

  36. Mini-writing #9 You have a friend who is struggling in a class. Now that you know so much about memory, identify 2 effects that we have learned about in class that pertain to memory that could help him. Explain each effect and how each effect would improve his test performance. Effortful processing Rehearsal Overlearning Serial position effect Spacing Effect Imagery Meaningfulness Mnemonics Chunking Retrieval Cues Hierarchies Context Effects Sleep
