  1. Planting False Memories: Are Transgressions As Believable As Victimizations?Presented at the annualUCI Undergraduate Research SymposiumBySara Holderfield May 13, 2006

  2. Have You Ever… • Forgotten something and then remembered it? • Believed an event happened one way only to find out you were wrong? This is normal forgetting and remembering. Usually, there are no dire consequences for mixing up the facts of a memory.

  3. Why Research False Memories? In the Early ’80’s, serious and bizarre sex abuse allegations started coming out due to “recovered memories”, and innocent people were being slandered at best, convicted at worst.

  4. Recanters "...I was able to figure out the so called 'recovered memories' were nothing more than visualizations from suggestions, guided imagery, therapist interpreted dreams, and hypnosis. You had nothing to do with my figuring out what was happening to me." From a letter by Deborah David to Dr. Colin Ross, a RMT and Multiple Personality Disorder therapist. www.religioustolerance.org

  5. Is it possible to plant false memories in a lab setting? 25% and 31% false memories using false profile Bernstein, Laney, Morris, Loftus (2005) 50% false memory using false photograph Wade, Garry, Read, Lindsay (2002)

  6. Is it possible to plant false memories in a lab setting? 26% complete memory for false item Porter, Yuille, Lehman (1999) 25% false memory using family involvement Loftus and Pickrell (1995)

  7. What about transgressions? We know we can plant false benign and false traumatic memories, but can we plant false memories for a transgression, like cheating?

  8. Why study transgressions? 175 wrongful convictions overturned as of May 4, 2006. Of the first 130 exonerations, 35 were false confessions. (www.innocenceproject.com) Studying false memories for a transgression is a move in the right direction for studying falseinternalized-confessions. (Kassin, 1997)

  9. Subjects N=170 UCI students=157, IVC=13 Male=51, Female=119 Range in age from 18-43

  10. “Social Perceptions” Study Confidence (SEI-1) And Personality survey Personalized profile Additional surveys 1 week

  11. Self-Esteem Scale Strongly Disagree Strongly Agree

  12. School Experiences Events Inventory Below is a list of events that may or may not have happened to you. Please read each event and rate how certain you are that the event (or a very similar event) did or did not happen to you. Definitely Definitely did not happen did happen

  13. “Social Perceptions” Study Confidence (LEI 1) and personality surveys Personalized profile Additional Surveys (SEI 2) 1week

  14. Subject Name: Molly Memory • Your self-esteem is high compared to others in your peer group. This disposition has led you to have a healthy respect for your own abilities. • You have had some successes and some failures so far, but your confidence in your own abilities to perform well is increasing over time. Studies suggest that increasing confidence levels lead to increasing success rates.

  15. Subject Name: Frank Fallible • Your self-esteem is low compared to your peer group. This disposition has led you to doubt your abilities even in the face of success. • Your relative lack of confidence contributed to your decision to cheat on a test during adolescence. According to a recent study, individuals who cheat during this critical time period tend to develop higher levels of test anxiety than those who refrain from cheating. Additional research suggests that those who admit to having cheated, even years after the fact, can reduce their test anxiety dramatically.

  16. Memory or Belief? 1. I made a goal during a soccer game in a PE class 2. I cheated on a test in 7th and/or 8th grade 3. I felt an earthquake during high school P M B

  17. Defining False Memories We need to distinguish true memories from false in some way. The criteria are: • Low confidence Day 1, Higher confidence Day 2 • “Memory” or “Belief”

  18. Confidence –subjects starting below 5 (on 7-pt scale) C O N F I D E N C E Experimental: t(43) = 5.86, p <.001

  19. Confidence –subjects starting below 5 (on 7-pt scale) C O N F I D E N C E Experimental: t(43) = 5.86, p <.001 Control: t(44) = 5.18, p <.001

  20. So what now? • Did we enter data wrongly? • Were subjects given the wrong profiles? • Are UCI students on to us and we have used the same profile too long?

  21. Future Directions • Compare UCI and IVC students. • Analyze differences between true and false memories. • Look at consequences for false beliefs. • Use a new method of manipulation and a less common false memory target.
