We’ll get back to our sea snail friend soon.

5. How do we remember?
How does memory help us?

6. What would you do to improve your memory?

7. Atkinson and Shiffrin’s Information Processing Model of Memory

8. Stages of Memory
Sensory memory– holds info. for only about a fraction of a second (sparkler trails, light)
Large capacity (thinking about the stimuli around us all the time)
Holds information briefly (about 2 seconds for auditory info. 250 milliseconds for visual info.)
Iconic memory – visual sensory memory

9. Short-term memory (STM) / working memory
limited capacity
stores unrehearsed info. for less than 20 seconds

19. Long-term memory (LTM) – unlimited capacity, holds info
Long-term memory (LTM) – unlimited capacity, holds info. over long periods of time.
Transferring information from STM to LTM
Rehearsal – process of repetitively verbalizing or thinking about the info.
Elaboration – refers to connection of new information to information already stored in memory
Chunking – groupings things together to ease memorization (parts of a phone number, chunking activity)

24. Retrieval – process of obtaining info. from stored memory
Recognition – memory retrieval, identify an object, idea or situation that has not been experienced. (associating new input with previous learning. Ex. Sound of an instrument playing an unfamiliar song)
Recall – active reconstruction of info. (pulling out or retrieving info. and assembling into something useful and/or describable)

25. Confabulation – “remembering” false info. Filling gaps in memory. (Why
Confabulation – “remembering” false info. Filling gaps in memory. (Why?, What affects this? Is this accurate?)
Elizabeth Loftus – Lost in the Mall experiment demonstrated how unreliable memory is
How accurate was your memory of your teachers? Was it the same as others?
Eidetic memory – “photographic memory”, 5% of children, very rare in adults. (skip reconstruction step, remember vivid details and info

26. Memory Questions Write a quick response to the following questions:
My most memorable experience was when…
Why do you remember this?
An experience I’d like to forget but can’t was when…
Explain why you think you can’t forget this experience.

27. What do you remember?

28. Remember This Take out your responses
Which type of memory was represented in your response to the questions on the last slide.

29. THE QUEST FOR MEMORY DRUGS
Memory Pill Questions
Would you use a pill to increase your memory?
What would you use it for? How would people benefit from such a pill?
What problems or ethical issues may arise with the use of such a pill?

30. Forgetting
Some argue that we do not forget info. in LTM, we simply can’t access it
Damage can cause loss – usually most recent memories
Repression – buried or blocked by subconscious (coping or defense mechanism)
Interference
Proactive – old memory blocks new one (new phone number, address)
Retroactive – new memory blocks old

31. A Pill to Forget

32. A Pill to Forget
When would you take a pill to forget? Explain a situation or circumstance.
Make a + / - T chart to describe the benefits and problems associated with a drug like Propanolol.
