False memory production in one experimental paradigm won't predict susceptibility to false memories in other paradigms

Abstract: 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.
