Identification accuracy for single‐ and double‐perpetrator crimes: Does accomplice gender matter?

There is an important mismatch between empirical research on the accuracy of eyewitness identification and the real world of criminal investigation. Most research models single‐perpetrator crimes, but in the real world, most crimes involve multiple perpetrators. This study examined how the number of perpetrators affects eyewitness identification by manipulating the gender of accomplices. Observers viewed a video of a staged crime. The crime was committed by a male or female perpetrator, who was presented alone or with an accomplice of the same or the opposite gender. The observers were then asked to identify the perpetrators from target‐present or target‐absent line‐ups. The results revealed a double‐perpetrator disadvantage, which was manifested in reduced identification accuracy on target‐present line‐ups. Importantly, however, the gender of the perpetrator or the accomplice had no effect on this disadvantage. This double‐perpetrator disadvantage is attributed to the need to divide attention between two concurrent people, compared to single‐culprit crimes, rather than an impairment of visual encoding processes. The implications of these findings are discussed.     

Cognition and lobar morphology in full mutation boys with fragile X syndrome

The aims of the present study are twofold: (1) to examine cortical morphology (CM) associated with alterations in cognition in fragile X syndrome (FXS); (2) to characterize the CM profile of FXS versus FXS with an autism diagnosis (FXS + Aut) as a preliminary attempt to further elucidate the behavioral distinctions between the two sub-groups. We used anatomical magnetic resonance imaging surface-based morphometry in 21 male children (FXS N = 11 and age [2.27-13.3] matched controls [C] N = 10). We found (1) increased whole hemispheric and lobar cortical volume, cortical thickness and cortical complexity bilaterally, yet insignificant changes in hemispheric surface area and gyrification index in FXS compared to C; (2) linear regression analyses revealed significant negative correlations between CM and cognition; (3) significant CM differences between FXS and FXS + Aut associated with their distinctive behavioral phenotypes. These findings are critical in understanding the neuropathophysiology of one of the most common intellectual deficiency syndromes associated with altered cognition as they provide human in vivo information about genetic control of CM and cognition.     

The Headscarf Effect: Direct Evidence from the Eyewitness Identification Paradigm

Internal and external features dominate familiar and unfamiliar face recognition, respectively. However, this finding is not universal; Egyptians showed a robust internal‐feature advantage for processing unfamiliar faces (Megreya & Bindemann, 2009). This bias was speculatively attributed to their long‐term experiences for individuating female faces with headscarves, which completely cover the external features. Here, we provided an empirical test for this suggestion. Participants from Egypt and UK were presented with a staged crime, which was committed by an own‐race woman with or without a headscarf. All participants were then asked to identify the culprit from a line‐up involving 10 faces with or without headscarves. British participants showed an advantage when the culprit left her hair uncovered. In contrast, Egyptian observers showed an advantage when the culprit wore a headscarf. This Egyptian headscarf effect was also replicated using British faces, suggesting that it reflects a specific characteristic of participant nationality rather than face nationality. These results therefore provide evidence for how culture influences cognition. Copyright © 2011 John Wiley & Sons, Ltd.

Personnel selection in the digital age: a review of validity and applicant reactions,and future research challenges

ABSTRACT

We present a targeted review of recent developments and advances in digital selection procedures (DSPs) with particular attention to advances in internet-based techniques. By reviewing the emergence of DSPs in selection research and practice, we highlight five main categories of methods (online applications, online psychometric testing, digital interviews, gamified assessment and social media). We discuss the evidence base for each of these DSP groups, focusing on construct and criterion validity, and applicant reactions to their use in organizations. Based on the findings of our review, we present a critique of the evidence base for DSPs in industrial, work and organizational psychology and set out an agenda for advancing research. We identify pressing gaps in our understanding of DSPs, and ten key questions to be answered. Given that DSPs are likely to depart further from traditional non-digital selection procedures in the future, a theme in this agenda is the need to establish a distinct and specific literature on DSPs, and to do so at a pace that reflects the speed of the underlying technological advancement. In concluding, we, therefore, issue a call to action for selection researchers in work and organizational psychology to commence a new and rigorous multidisciplinary programme of scientific study of DSPs.
