False Memory Tasks Do Not Reliably Other False Memories

Several laboratory techniques have been developed over the last few decades that reliably produce memory distortions. However, it is unclear whether false memory production in one experimental paradigm will predict susceptibility to false memories in other paradigms. In Experiment 1, 202 undergraduates participated in a misinformation experiment and semiautobiographical tasks involving three measures of memory distortion (suggestion, imagination, emotion). We established high internal consistency in individual differences measures and statistically significant experimental effects where we would expect them (e.g., the misinformation effect). However, false memory production in one task did not predict false memories in other paradigms. In Experiment 2, 163 adults participated in a misinformation experiment, a false memory word list task (Deese–Roediger–McDermott), and semiautobiographical false news story tasks. Again we found no consistent predictive relationships among various false memories. In both studies, no individual differences predicted memory distortion susceptibility consistently across tasks and across experiments. At this time, false memory production in a given laboratory task does not appear to adequately predict false memories in other tasks, a finding with implications for using these tasks to predict memory distortion in real world situations

Current Issues and Advances in Misinformation Research

Abstract Eyewitnesses are often called upon to report information about what they have seen. A wealth of research from the past century has demonstrated, however, that eyewitness memory is malleable and vulnerable to distorting influences, including the effects of misinformation. In this article, we review recent developments in research related to the misinformation effect, including individual differences in susceptibility, neuroimaging approaches, and protective interview procedures that may better elicit accurate event details. We conclude with a section on related false memory research

Sleep deprivation and false confessions.

False confession is a major contributor to the problem of wrongful convictions in the United States. Here, we provide direct evidence linking sleep deprivation and false confessions. In a procedure adapted from Kassin and Kiechel [(1996) Psychol Sci 7(3):125-128], participants completed computer tasks across multiple sessions and repeatedly received warnings that pressing the "Escape" key on their keyboard would cause the loss of study data. In their final session, participants either slept all night in laboratory bedrooms or remained awake all night. In the morning, all participants were asked to sign a statement, which summarized their activities in the laboratory and falsely alleged that they pressed the Escape key during an earlier session. After a single request, the odds of signing were 4.5 times higher for the sleep-deprived participants than for the rested participants. These findings have important implications and highlight the need for further research on factors affecting true and false confessions

Sleep deprivation and false memories.

Many studies have investigated factors that affect susceptibility to false memories. However, few have investigated the role of sleep deprivation in the formation of false memories, despite overwhelming evidence that sleep deprivation impairs cognitive function. We examined the relationship between self-reported sleep duration and false memories and the effect of 24 hr of total sleep deprivation on susceptibility to false memories. We found that under certain conditions, sleep deprivation can increase the risk of developing false memories. Specifically, sleep deprivation increased false memories in a misinformation task when participants were sleep deprived during event encoding, but did not have a significant effect when the deprivation occurred after event encoding. These experiments are the first to investigate the effect of sleep deprivation on susceptibility to false memories, which can have dire consequences
