Abstract

The present study was designed to assess the effects of format of recall and type of stimuli on group performance on a recall task to determine the accuracy of provided eyewitness testimonies under various conditions. To assess this, a 2x2 between subject design was used. 72 undergraduates from a private, midwestern institution participated with a mean age of 19.04. These undergraduates viewed or listened to a clip of a minor crime and subsequently engaged in either collaborative or individual recall in randomly assigned triads. A 2x2 between-subjects ANOVA with format of recall and type of stimuli as the independent variables was utilized. The results demonstrated that, on average, those in collaborative groups significantly outperformed their individual group counterparts in regards to the accuracy of their testimony. Additionally, those with a visual witnessed event created significantly more accurate testimonies than those who encountered the auditory witnessed event. Finally, a significant relationship was found between format of recall and type of stimuli stimuli such that when in the auditory only condition, collaborative recall resulted in significantly more accurate details recalled than in the individual condition. However, there was no difference in the number of details recalled that occurred in the visual conditions. These findings may have implications for the future of eyewitness testimony collection, providing insight as to the accuracy of eyewitness testimonies when the event is witnessed under visual only or auditory only conditions.

Collaborating on Recall Enhances Accuracy for Auditorily-Experienced, but Not Visually-Experienced Witnessed Events
