Repetition and Reconfiguration: Demand‐Based Confabulation in Initial Eyewitness Memory

Repeated recall, as a result of repeated questioning, is typical of situations involving eyewitness evidence. The present study addressed questions of eyewitness performance with reference to repeated questioning in an initial interview, in a format based on actual police procedures. This experiment focused on eyewitness accuracy, eyewitness confidence, and the addition of false details to eyewitness accounts. Ninety‐two adult respondents were asked to recall all the information they could from a single viewing of a scene depicting an assailant aiming a handgun at a victim. This initial question was followed by three additional questions, in which respondents were asked to report any additional details they could recall. On average, respondents provided several times as many correct as false details to the initial question. However, performance deteriorated significantly to the three subsequent questions; on average, across the three subsequent questions, witnesses recalled nearly as much false as accurate information. Witness confidence was positively related to amount of accurate information recalled. However, confidence was also positively related to the number of instances of erroneous recall. These results indicate that reconfigurative dynamics begin to operate, producing confabulated responses in response to questioning demands, as early as the initial interview. This work may also help to clarify the critical relationship between accuracy and confidence in eyewitness reportage, at least within the framework reflected by the present research.
