Abstract

This research aimed to conduct an initial investigation into the relationships between the “misinformation effect” and trauma exposure, posttraumatic stress disorder (PTSD) and depression. Study 1 was a pilot study developing an online misinformation paradigm that could assess the influence of emotion and arousal on memory distortions. Participants (n = 162, Mage = 39.90; SD = 10.90) were recruited through TurkPrime. In Study 2 community members (n = 116, Mage = 28.96; SD = 10.33) completed this misinformation paradigm and measures of trauma exposure, PTSD, and depression. Study 1 found memory for central details was better for high-arousal than low-arousal and neutral-arousal images. Peripheral memory appeared worse for negative and neutral images than positive images. Study 2 found trauma exposure and PTSD symptoms predicted the misinformation effect; greater trauma exposure was associated with a greater proportion of errors, while PTSD was associated with a lower proportion of errors. Valence and arousal did not influence these associations. These findings have important implications in clinical and legal contexts where individuals with a history of trauma, or who are experiencing symptoms of PTSD or depression, are often required to recall emotionally-laden events. There is a surprising dearth of research into the misinformation effect in clinical populations and further research is required.
