False claims about false memory research.

Pezdek and Lam [Pezdek, K. & Lam, S. (2007). What research paradigms have cognitive psychologists used to study "False memory," and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been (1) misusing the term "false memory," (2) relying on the wrong methodologies to study false memories, and (3) misapplying false memory research to real world situations. We review each of these claims and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors.

Using source cues and familiarity cues to resist imagination inflation.

To investigate whether people can resist imagination inflation--the imagination-induced increased confidence that fictitious childhood events really happened--we gave them different types of cues. In a three-stage procedure, participants: (1) rated their confidence that a list of childhood events had happened to them, (2) imagined some of these events, and (3) made confidence ratings a second time. Subjects received either no cues about the source of the imagined event, an additional source cue (perspective), an additional familiarity cue (a plausibility questionnaire), or both cues. Only subjects who had both types of cues resisted imagination inflation. These results suggest that additional cues can sometimes safeguard people from becoming more confident that fictitious events were genuine experiences.

Imagination or exposure causes imagination inflation.

To examine the effects of exposure to complex autobiographical events on imagination inflation, subjects performed a 3-stage procedure. First, they rated their confidence that a list of events had happened in their childhood. Second, subjects imagined and paraphrased complex fictitious events 0, 1, 3, or 5 times. Finally, they rated their confidence for the childhood events a second time. We found that subjects became more confident that the fictitious events really did happen in childhood, regardless of whether they were imagined or paraphrased. There was no repetition effect beyond that of a single exposure. Taken together with the results of other research, our data suggest that the greater processing fluency associated with the target events drives imagination inflation.

The power of the spoken word: sociolinguistic cues influence the misinformation effect.

We investigated whether the sociolinguistic information delivered by spoken, accented postevent narratives would influence the misinformation effect. New Zealand subjects listened to misleading postevent information spoken in either a New Zealand (NZ) or North American (NA) accent. Consistent with earlier research, we found that NA accents were seen as more powerful and more socially attractive. We found that accents per se had no influence on the misinformation effect but sociolinguistic factors did: both power and social attractiveness affected subjects' susceptibility to misleading postevent suggestions. When subjects rated the speaker highly on power, social attractiveness did not matter; they were equally misled. However, when subjects rated the speaker low on power, social attractiveness did matter: subjects who rated the speaker high on social attractiveness were more misled than subjects who rated it lower. There were similar effects for confidence. These results have implications for our understanding of social influences on the misinformation effect.

Examining memory for heterosexual college students' sexual experiences using an electronic mail diary.

To examine memory for sexual expenences, the authors asked 37 sexually active, nonmonogamous, heterosexual college students to complete an e-mail diary every day for 1 month. The diary contained questions about their sexual behaviors. Six to 12 months later, they returned for a surprise memory test, which contained questions about their sexual experiences from the diary phase. They were asked about their sexual partners, the types of sexual experiences they had, and condom use. Participants underreported the number of partners they had, but they overreported both sexual experiences and condom use. The results have implications for both sexual health educators and for people who engage in high-risk sexual behaviors.
