Summary. In this collaboration between labs at University of Nebraska, Lincoln and UC Irvine, Wylie et al. and Patihis et al. conducted meta-analyses independently of one another, and this chapter represents the fusing of those two projects.  For the first time there are enough articles in existence to conduct a thorough meta-analysis on the misinformation effect in older adults and come to a conclusion that is relatively firm. Summing many studies we found older adults are more susceptible to the misinformation effect (compared to young adults). However we also noted more than one way of reducing this susceptibility, and argue that care should be taken not to discriminate against older eyewitnesses. (read more

Summary. This study investigates how beliefs about memory have changed since the 1990s, and how they currently vary amongst psychologists and therapists of various stripes. The general public and undergraduates are also included. We also investigate whether there is anything different (in terms of personality, critical thinking, intelligence, empathy, etc) between people who believe in repressed memory, compared to those who don't. We found less belief in repressed memory among mainstream clinicians today compared with the 1990s. Groups that contained research-oriented psychologists and memory experts expressed more skepticism about the validity of repressed memories relative to other groups. A substantial gap between the memory beliefs of clinical-psychology researchers and those of practitioners persists today.

Summary. In this direct submission to PNAS, similar rates of memory distortion were found in highly superior autobiographical memory (HSAM) and control participants across a number of tasks. We found that 100% of participants, in both groups, indicated many false recognitions of words that were not actually presented (HSAM range 8-20 out of 20; average 14 in both groups). About 90% of participants had at least one overall false memory for a detail in a series of photographs on a misinformation task. Following suggestion, about 20% of participants reported a false rememberance of seeing non-existent news footage of the actual crash of United 93 on 9/11.  A subsequent imagination exercise resulted in several participants in both groups becoming more sure they had seen the footage. HSAM and control participants were similarly inconsistent in their memory for negative emotions in the week after 9/11 (inconsistent from one week to the next in 2012). (pdf here)

Interests (cont): Is there a type of person that is particularly vulnerable to false memories; in other words is there a kind of false-memory-personality trait?  The flip side of this is a crucially important question, practically speaking, and that is: Is anyone immune from memory distortions?  Should anyone be exempt from the kind of caution and scrutiny that we advocate for in regards to memory contamination in the judicial system and psychotherapy?  Should people, for example, with very strong memory ability be excluded from the cautionary approach to eyewitness testimony--an approach that emphasizes the fallibility and malleability of memory?

As well as memory distortion research, I have recently also been peripherally involved in one of the most interesting new developments in memory science: highly superior autobiographical memory (HSAM) research.

Another interest is in other practical applications related to what people believe about how memory works, especially repressed memory, because this, again, affects how memory evidence is recovered and assessed in legal and therapy settings.

In addition to practical applications, I am intrigued by various theory questions. For example, questions about the standing of, including predictive power of, various memory distortion theories (e.g. source monitoring, fuzzy trace, etc.). Another interest is in how affective adaptation and emotion appraisal theory can explain distortions in memory for past felt emotion. Also of interest is the recent spate of reconsolidation articles published in top tier journals. And a final interest in a skeptical capacity is in theories such as motivated forgetting, catharsis theory, and various views on how traumatic memory works.

Also of interest is scientific skepticism and distinguishing science from pseudoscience. I particularly like Karl Popper's suggestion that the ideal approach to science is to actively seek disconfirming evidence for falsifiable hypotheses, and like to apply this idea to both science and to critical thinking outside of the lab--for example to avoid groupthink.
