Distinguishing accurate from inaccurate eyewitness identifications with an optional deadline procedure

Abstract

Two experiments examined the efficacy of an optional deadline lineup procedure for distinguishing correct from incorrect eyewitness identification decisions. The procedure involved briefly presenting the lineup, removing the lineup from view, then giving participants the option of either making an identification decision or viewing the lineup again. When compared with participants operating under a forced deadline (i.e. forced to respond after the brief presentation) or standard lineup instructions, the optional deadline procedure identified participants with an impressive probability of having made a correct identification when used with target-present lineups and biased instructions. With unbiased instructions, the optional deadline produced clear discrimination between correct and incorrect identification decisions for choosers and, importantly, also for non-choosers. Possible strategies for improving the efficacy of the procedure are suggested.     

Negotiating Citizenship: The case of foreign domestic workers in Canada

This paper argues that most conceptualizations of citizenship limit the purview of the discourse to static categories. ‘Citizenship’ is commonly seen as an ideal type, presuming a largely legal relationship between an inidividual and a single nationstate - more precisely only one type of nation-state, the advanced capitalist postwar model. Alternatively, we suggest a re-conceptualization of citizenship as a negotiated relationship, one which is subject therefore to change, and acted upon collectively within social, political and economic relations of conflict. This dynamic process of negotiation takes place within a context which is shaped by gendered, racial and class structures and ideologies; it also involves international hierarchies among states. Citizenship is therefore negotiated on global as well as national levels. This conceptualization is demonstrated by way of identifying one particular set of experiences of negotiated citizenship, involving foreign domestic workers in Canada. As non-citizens originating from Third World conditions, this is a case involving women of colour workers, highly prone to abusive conditions, and under the direction of employers who are more affluent First World citizens and predominantly white women. Original survey data based on interviews with Caribbean and Filipino domestic workers in Canada are used to demonstrate the varied, creative and effective strategies of two distinctive groups of non-citizens as they attempt to negotiate citizenship rights in restrictive national and international conditions.

Invited Commentary: Understanding Brain Mechanisms of Pain Processing in Adolescents’ Non-Suicidal Self-Injury

Whereas non-suicidal self injury (NSSI) is reported in 13–23% of adolescents and is an increasingly studied topic, there has been little investigation into the pathophysiology behind self-injury. This commentary examines recent research into pain and emotional distress to discuss implications for the manner we should understand, research, and treat NSSI in the future. Research indicates that adolescents may be particularly vulnerable to NSSI behaviors due to neurodevelopmental changes in the processing of distress and pain. Additionally, emotional distress and physical pain neural pathways may have been altered in these individuals, leading to the development of NSSI behaviors during adolescence when changes in ongoing brain development may lead to further emotional dysregulation and poor impulse control. Further studies that directly characterize the relationship between emotional distress and physical pain in adolescence, as well as the neural differences between self-injurers and non-self-injurers, are needed.     

Change and continuity across the 9/11 fault line: rethinking twenty-first-century responses to terrorism

This article asks the following questions. Which terrorism threats, challenges and responses did key players consider to have been decisively changed by 9/11? On close inspection now, nearly two decades after those attacks, how are we to assess such claims? What did 9/11 really change regarding terrorism and counterterrorism? And what remained unaltered? The article’s central argument is this: some western states exaggerated the extent to which terrorist threats and challenges had been changed by 9/11 and, as a consequence, they did significantly alter some of their responses to terrorism; but at the heart of this ironic process was the tragic reality that, had there been a more serious-minded and historically sensitive recognition of how little had necessarily been changed by 9/11 in terms of terrorist threats and challenges, then the twenty-first-century experience of non-state terrorism would have been much less painful than has been the case in practice.
