Pennington: "Effect of memory structure on judgement"
- Aim: test the hypothesis that jurors are more easily persuaded by "story order" than the "witness order".
- Participants: 130 university students.
- Method: ~lab experiment ~mock trial ~evidence presented via taperecorder (of a real case) ~mock jurors had to answer questions about the evidence, present a verdict and rate their confidence (1-5).
- Results: when prosecution used story order a guilty verdict was returned 78% of the time. When the defence used story order a guilty verdict was received 31% of the time. The mock jurors were also more confident of their verdict when the evidence was received in story order.
- Conclusion: the way in which information is presented will affect the jurors memory of the case and chronological order is more likely to be influential in changing the verdict as it is easier for jurors to recall later during the deliberation process
