Victimizations?

Have You Ever…• Forgotten something and then

remembered it?

This is normal forgetting and remembering. Usually, there are no dire consequences for mixing up the

facts of a memory.

• Believed an event happened one way only to find out you were wrong?

Page 3: May 13, 2006

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.

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.

Is it possible to plant false memories in a lab setting?

50% false memory using false photograph

Wade, Garry, Read, Lindsay (2002)

25% and 31% false memories using false profile

Bernstein, Laney, Morris, Loftus (2005)

Is it possible to plant false memories in a lab setting?

25% false memory using family involvement

Loftus and Pickrell (1995)

26% complete memory for false itemPorter, Yuille, Lehman (1999)

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?

Page 8: May 13, 2006

Why study transgressions?175 wrongful convictions overturned as of

May 4, 2006.

Of the first 130 exonerations, 35 were false confessions.

Studying false memories for a transgression is a move in the right direction for studying

false internalized-confessions.(Kassin, 1997)

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.

Page 15: May 13, 2006

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.

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

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”

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?

Page 21: May 13, 2006

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.
