Memory & Cognition
Misinformation effect, Retrieval enhanced suggestibility, Interim testing, Processing
Research suggests that testing prior to the presentation of misinformation influences how that misinformation is processed. The present study examined the relationship between testing, the demands of misinformation narrative processing, and memory for original and post-event information. Using response latencies to a secondary task, we tested whether prior testing influenced the available resources for secondary task processing. Additionally, we investigated whether changes in narrative processing were specific to critical details tested earlier. Participants engaged in an eyewitness memory paradigm in which half were tested prior to receiving the post-event narrative. Participants responded to the secondary task at specified time points during the narrative. All participants took a final memory test after listening to the post-event narrative. We found that testing interacted with the placement of the secondary task. When responding on the secondary task was closely linked to the presentation of previously tested critical details in the narrative, retrieval-enhanced suggestibility was reduced on tests of event memory (Experiment 1) and increased post-event information learning was revealed on tests of narrative memory (Experiment 2).
