  24. Penny Exercise

  25. Encoding Failure • Represents a failure to encode. • The details of a penny are not that important to us…absent-mindedness • Also, we think about what should be, not what is.

  26. Capital City Exercise • Name as many as you can without help. • Write the first few letters if you only remember part of the word. • I will give you a hint.

  27. What type of memory failure does this exercise represent?

  28. Interference • Proactive Interference- When an older memory disrupts recall of a newer memory. • Retroactive Interference- When a more recent memory disrupts recall of an older memory.

  29. Repression vs. Retrieval Exercise • Precious Stone: First • Fish: Second • State: Third • Insect: Second • Type of Music: First • Alcoholic Beverage: Third • Color: Second • Military Title: Third • Article of Clothing: First • Sport: Second 11. Musical Instrument: First 12. Four-Footed Animal: Third 13. Occupation: First 14. Weapon: Third 15. Furniture: Second 16. Type of Fuel: Second 17. Disease: First 18: Vegetable: Third 19. Type of Vehicle: Second 20. Body Part: First

  30. Memory Construction • Have you ever had a strong, vivid memory and later learned you were wrong (or realized that what you remember could not have happened)? If so, write it down. • Why do you think this occurred? • We will share our answers…

  31. Constructs • A complex idea resulting from the combination of simpler ideas • Not directly observable • Something built systematically • Constantly changing

  32. Answer the following in groups: • What if the simpler ideas/experiences from which we construct our memories are not all accurate? • What does this mean for our identity?

  33. War of the Ghosts • We slightly alter images, memories, and ideas to fit into our own method of understanding/remembering • Listen very carefully!

  34. How/Why does our memory transform material? • Accepted/conventional representations - That couldn’t have been a wolf…it was a dog • Some features cannot be labeled until a recognized form is produced -If it doesn’t fit anything that we know/are used to, we have trouble recognizing or remembering it…chemistry anyone?

  35. Bartlett’s Conclusions • After first recall, the general form or outline stays the same • Form and items become stereotyped and then don’t change • Story is rationalized (westernized)- symbolization • We simplify, omit, and transform images into things we recognize

  36. Misinformation Effect • Incorporating misleading information into a memory. • Examples?

  37. Eyewitness Testimony • Identify the bomber on the roof… http://www.psychology.iastate.edu/~glwells/theeyewitnesstest.html

  38. Child Testimony • Imagine that you are a therapist or attorney who needs to interview a child about a possible case of abuse. Describe the procedure that you would use to ensure that the answers are as accurate as possible.

  39. Is Repression Real? • Our memories are anchored by context cues…If we dig deep enough, we can retrieve them.

  40. Improving Memory Group Exercise • Develop a study plan for a student using 4-5 of the memory techniques in your book. • Imagine that the student has a psychology test approaching, and they want a detailed plan of methods, techniques, and examples that they can use to succeed on this exam.
