Recent research in decision-making has demonstrated the “dud-alternative effect”—the tendency to become more confident that
a chosen response option is correct if it is surrounded by implausible response options (Windschitl & Chambers, J Exp Psychol
30:198–215, 2004). This finding may be applicable to a lineup task: The presence of duds (i.e., highly dissimilar fillers) may increase a
witness’s confidence that an identified (non-dud) lineup member is the criminal. Four studies (N = 665) demonstrate that the mere presence of highly dissimilar fillers inflates witnesses’ confidence in a mistaken identification
(Studies 1–4), provides evidence that this confidence inflation is due to the duds inflating the perceived similarity of the
other lineup members to the criminal (Studies 2, 3), and delineates some conditions under which the effect holds (Studies
3, 4). The addition of highly dissimilar lineup members, far from being inert, as is often implicitly assumed, can bias witnesses’
confidence reports. 相似文献

A range of chemical techniques were utilised for the enhancement of footwear impressions deposited on a variety of fabric types of different colours with urine as a contaminant. A semi-automated stamping device was used to deliver test impressions at a set force to minimise the variability between impressions; multiple impressions were produced and enhanced by each reagent to determine the repeatability of the enhancement. Urine samples from different donors were analysed using a spectrofluorophotometer revealing differences between individuals. Results indicated that the enhancement of footwear impressions in urine was possible using amino acid staining techniques whereas protein stains failed to achieve successful enhancement. 相似文献
