How prior testing impacts misinformation processing: A dual-task approach.

Area of Science:

• Cognitive Psychology
• Eyewitness Memory Research

Background:

• Prior testing can influence memory processing and susceptibility to misinformation.
• Understanding how testing interacts with narrative processing is crucial for eyewitness testimony.

Purpose of the Study:

• To investigate the relationship between prior testing, misinformation narrative processing demands, and memory for original and post-event information.
• To determine if prior testing affects cognitive resource availability during misinformation processing.
• To examine if narrative processing changes are specific to previously tested details.

Main Methods:

• An eyewitness memory paradigm was employed with participants tested before receiving a post-event narrative.
• Response latencies to a secondary task were measured during narrative presentation to assess processing demands.
• A final memory test evaluated recall of original and post-event information.

Main Results:

• Testing interacted with the timing of the secondary task within the narrative.
• When the secondary task was closely linked to previously tested details, retrieval-enhanced suggestibility was reduced for event memory.
• Increased learning of post-event information was observed for narrative memory when testing and task timing were aligned.

Conclusions:

• Prior testing can mitigate suggestibility to misinformation, particularly when cognitive demands align with tested material.
• The timing of cognitive tasks relative to misinformation exposure and prior testing significantly influences memory outcomes.
• Findings have implications for understanding memory accuracy in legal and everyday contexts.
