The Dud Effect: Adding Highly Dissimilar Fillers Increases Confidence in Lineup Identifications

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.     

Chemical enhancement of footwear impressions in urine on fabric

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.     

Unmasking Deviance: The Visual Construction of Asylum Seekers and Refugees in English National Newspapers

This paper explores the visual representation of asylum seekers and refugees delineating how English newspaper imagery constructs such groups as deviant and dangerous. A qualitative visual analysis of nine of the major national newspapers demonstrates how mediated images of asylum seekers focus upon three distinct ‘visual scenarios’ in the discovery of deviance, which collectively demonstrate how the social portrayal of the criminal immigrant fuses the otherness of the stranger with the otherness of the deviant. First, the faceless and de-identified stranger enables the construction of a panoply of feared subjects. Second, stigma is implicitly illustrated, deviance obliquely intimated and ‘spoiled identities’ constructed. Third, the mask is removed, the asylum seeker is identified and their deviant status confirmed. Such a process is reinvented, repeated and reworked in news stories, with deviance becoming increasingly engrained and entrenched in the image of the asylum seeker. This paper details how the repetition of specific visual scenarios in newspaper reporting contribute to the construction of ‘noisy’ panics about asylum seekers and asylum seeking. Moreover, it argues that such imagery is key to the construction of asylum as an issue of security, which necessitates a policy approach that is exclusionary in nature.
