Memory

2. Memory Memory Construction Misinformation and Imagination Effects A trial at the Old Bailey in London, as drawn by Thomas Rowlandson and Augustus Pugin for Ackermann's Microcosm of London (1808-11).

3. In over two thirds of the first 138 postconviction DNA exonerations, mistaken eyewitness identification played a major part in the wrongful conviction. Modern technology is proving what scientists, psychologists, and legal scholars have noted for years: eyewitness identification is often faulty and is the major cause of wrongful convictions.Identifications are even more problematic when they are based on observations made under stress or in less than ideal conditions(e.g. darkness, from a distance).

Yes Marvin Anderson Because Anderson had no criminal record, the officer went to Anderson's employer and obtained a color employment photo identification card. The victim was shown the color identification card and a half dozen black-and-white mug shots and then asked to pick the perpetrator. The victim identified Anderson as her assailant. Within an hour of the photo spread, she was asked to identify her assailant from a lineup…She identified him in the lineup as well.

Yes Ronald Cotton Arising from this case is the incredible story of Jennifer Thompson, the victim who had identified Cotton. An aspiring college student at the time of the crime, she made it her purpose to study the assailant's face so that he would be brought to justice. She identified the wrong man. Today, Ms. Thompson speaks out about her experiences and the dangers of relying solely upon single eyewitness testimony to convict. http://www.youtube.com/watch?v=u-SBTRLoPuo&feature=fvsr http://www.youtube.com/watch?v=WFRiDtUbeAQ&feature=fvsr

7. How fast were the cars going when they ___ each other? [smashed, collided, bumped, hit, contacted] http://www.youtube.com/watch_popup?v=Rg5bBJQOL74&vq=medium

8. 40.8 mph 31.8 mph 0%

9. Participants who were asked a leading question (with “smashed”) were much more likely to remember broken glass two weeks later than were other participants.

10. Misinformation effect—after exposure to misinformation, many people misremember.

12. The innovation:the sequential police lineup procedure, in which a witness is shown suspects one at a time instead of all at once (simultaneously).

14. The rationale:psychologist Gary Wells’ discovery that when shown sequential lineups, people make absolute judgments, which lead to much lower rates of misidentification.

15. The result:sequential lineups cut eyewitness misidentification in half compared to simultaneous lineups. Fewer innocent people go to jail. http://www.npr.org/player/v2/mediaPlayer.html?action=1&t=1&islist=false&id=137652142&m=137656136

17. Memory Memory Construction Repressed or Constructed Memories of Abuse?

18. Sigmund Freud proposed that we repress painful memories to protect our self-concept and minimize anxiety. Sigmund Freud, by Max Halberstadt, 1921

19. More recently, people have been accused, and sometimes convicted, of sexual abuse based on repressed memories.

20. I find myself at the center of an increasingly bitter and fractious controversy. On one side are the “True Believers” who insist that the mind is capable of repressing memories and who accept without reservation or question the authenticity of recovered memories. On the other side are the “Skeptics” who argue that the notion of repression is purely hypothetical and essentially untestable, based as it is on unsubstantiated speculation and anecdotes that are impossible to confirm or deny. - Elizabeth Loftus Credit: Don Shrubshell

21. Credit: Jongleur100 In one study by Loftus and colleagues, participants were asked questions about three events that had actually happened to them as children, and questions about one event that had not happened: getting lost in a shopping mall.

22. Credit: Jongleur100 By the third interview, approximately 25% of participants remembered the false event as a real event. Thus, it seems to be possible to “implant” false memories. http://www.youtube.com/watch_popup?v=PQr_IJvYzbA&vq=small#t=14

24. Chapter Review What is memory, and how is it understood from an information processing perspective? What are encoding, storage, and retrieval processes, and what are some factors that influence them? What are some explanations for forgetting?

25. Chapter Review What does it mean to say that memory is “reconstructive” and what are some consequences of this in the real- world?
