3. Memory Capacity to encode, store, and retrieve information What is Memory?

4. Types of Memory Explicit Memory Conscious effort to recover information Implicit Memory Availability of information through memory without conscious effort

5. Types of Memory Declarative Memory Information (e.g. facts and events) Procedural Memory How tasks are carried out

6. Memory Processes Encoding Mental representation is formed in memory Storage Retention of encoded material Retrieval Recovery of stored information

7. What’s Wrong With This Picture?

8. The Flow of Information In and Out of Long Term Memory

9. Let’s do a demonstration of the impermanence of some memories!

10. Look at the following visual scene for about 10 seconds …

11. How much can you remember from this scene?

12. Memory Use for the Short -Term What tool was the little boy at the bottom holding?What is the middle man at the top doing? In the lower right hand corner, does the woman’s umbrella handle hook to the left or to the right?

13. Iconic Memory Visual memory Eidetic imagery George Sperling Partial-report procedure

14. Recall by the Partial-Report Method

15. Short –Term Memory Short-term Memory Preservation of recent experiences Retrieval of information from long- term memory

16. Short –Term Memory Capacity Limits of STM Memory SpanGeorge Miller 7 (plus or minus 2)

17. Short –Term Memory RehearsalMaintenance rehearsalChunking Process of reconfiguring items by grouping them on basis of similarity or some other organizing principle

18. Short-Term Memory Recall without Rehearsal

19. Reasoning and language comprehension Phonological loop, visuospatial sketchpad, central executive, episodic buffer (Baddeley, 2002, 2003) Working Memory

20. Sample Item from a Test of Operation Span

21. Long-Term Memory Long-term Memory (LTM) Storehouse of all experiences, events, information, emotions, skills words, categories, rules, and judgments acquired from sensory and short term memories Preservation of information for retrieval at any later time

22. Long-Term Memory Retrieval CuesRecallRecognition

23. Long-Term Memory Episodic memory Memories for things personally experienced Semantic memory Generic, categorical memories

24. Dimensions of Long-Term Memory

25. Context and Encoding Subsequent retrieval of information IF cues retrieved at time of recall are consistent with those present at time of encoding Encoding Specificity

26. Context and Encoding Recall of beginning and end items in list Primacy Effect Recency Effect Serial Position Effect

28. Context and Encoding Extent to which particular item stands out from or is distinct from other items in time Temporal Distinctiveness

30. Process of Encoding and Retrieval Levels of Processing Information processed at deeper level is more likely to be retained

31. Processes of Encoding and Retrieval Transfer-appropriate Processing Memory is best when type of processing carried out at encoding matches processes carried out at retrieval

32. Processes of Encoding and Retrieving Levels of Processing Theory Suggests the deeper the level at which information is processed, the more likely it is to be retrieved in memory

33. Why We Forget “Facts crammed at examination time soon vanish, if they were not grounded by other study and later subjected to a sufficient review.” (Hermann Ebbinghaus, 1865)

34. Ebbinghaus’ Forgetting Curve

35. Why We Forget Interference Retrieval cues do not point effectively to one specific memory Proactive interference Information acquired in past makes it more difficult to acquire new information Retroactive interference Acquisition of new information makes it difficult to remember old information

36. Proactive and Retroactive Interference

37. Improving Memory for Unstructured Information Elaborative Rehearsal Improving memory by enriching encoding of information Mnemonics Method of Loci Peg-word Method Metamemory Cue familiarity Hypothesis Accessibility Hypothesis
