The present study investigated the effect of extraversion and induced arousal on eyewitness accuracy. Undergraduate students scoring in the top or bottom 40% of an extraversion scale viewed a one minute crime scenario contained within a 13 minute video and were later asked to recall the details of the crime scenario. Participants were aroused above baseline, measured with a hand held digital pulse monitor, one minute prior to the crime scenario, with a burst of 60db (low) white noise, 75db (moderate) white noise or 90db (high) white noise. Participants were later asked to complete a forced choice cued recall questionnaire to determine whether or not extraversion and arousal had affected the accuracy of recall of the crime scenario. It is hypothesized that (a) for introverts, recall will be better when arousal is low and will be impaired when arousal is high, compared to controls, whereas, (b) for extraverts, recall will be better when arousal is moderate and will be impaired when arousal is low, compared to controls. Results were satistically insignificant.
