Witness Accuracy (witness + accuracy)
Selected AbstractsThe influence of lawyers' questions on witness accuracy, confidence, and reaction times and on mock jurors' interpretation of witness accuracyJOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 3 2010Mark R. Kebbell Abstract Two studies demonstrate the influence of lawyers' complex questions on mock-witness accuracy, confidence, and reaction times and on the interpretation of witness accuracy by mock jurors. In study one, 32 mock witnesses were shown a short film and then questioned either with lawyers' complex questions or simple alternatives. In Study 2, 20 mock jurors viewed video footage of the mock witnesses assigned to each of the two previous conditions and were asked to rate their confidence in the witnesses' answers. The findings of the two studies indicated that lawyers' use of confusing questions reduce not only accuracy but also speed of response and both witnesses' and jurors' ability to determine accuracy. The implication of these findings is straightforward, lawyers should ask simple questions wherever possible. Copyright © 2010 John Wiley & Sons, Ltd.

McAuliff This study investigated potential differences between expert and lay knowledge of factors influencing witness suggestibility. Expert psychologists (N,=,58), jurors (N,=,157), and jury-eligible undergraduates (N,=,220) estimated the effects of misleading information on witness accuracy for three age groups in various conditions. Respondents possessed similar knowledge of age-related trends in suggestibility, the positive effects of a pre-misinformation warning, and the negative influence of longer delays between the event/misinformation and event/final memory test. Compared to experts, laypeople underestimated the size of suggestibility differences between age groups and lacked knowledge about how event detail centrality, witness participation, and source prestige can increase witness suggestibility. Laypeople rated themselves as being largely unfamiliar with witness suggestibility research and thought that expert testimony would be beneficial. These data shed light on the potential helpfulness of expert testimony in cases involving witness suggestibility. Copyright © 2006 John Wiley & Sons, Ltd. [source] | ||||||||||
