title: The impact of outcome valence on the susceptibility to suggestion for post-event causal misinformation.
abstract: Recent research has demonstrated that people are especially susceptible to false memory development for suggested misinformation that fills a causal role (i.e., explains some known outcome) (Chrobak & Zaragoza, 2013). However, little is known about how factors associated with the witnessed outcome impact the likelihood of false memory development. In the present study, outcome valence (negative, positive, or neutral) was manipulated. Participants heard several short stories that contained an outcome (e.g., a counselor getting promoted) that lacked a causal explanation. Participants were subsequently exposed to suggested causal misinformation that explained that outcome (e.g., the counselor performed an impressive act the previous day) and then were tested on their memory for the original event. Results indicated that participants incorrectly reported the suggested causal information more when it explained either a positive or negative outcome as opposed to a neutral outcome. Theoretical and practical implications of these findings are discussed.
