Witnessing a crime can be a highly stressful situation, eliciting arousal levels that may affect eyewitness memory performance. In two experiments, participants watched a mock crime with varying arousal intensities (neutral, robbery, and murder), and provided reports after varying retention intervals (immediate testing, 7 days, 14 days or 21 days). Results showed that arousal did not have a significant main effect on eyewitness memory recall. Eyewitness memory performance was stronger for the event with higher arousal only after a 7 days retention interval, but performance was comparable across all arousal conditions in longer retention intervals. Theoretical and practical implications related to the evaluation of eyewitness testimony are discussed.
