The present study tested the Two-Judgment Theory of Eyewitness Identification Accuracy. Specifically, the extent to which participants were able to engage in an absolute judgment strategy was manipulated by varying the time available to view a lineup. Providing a limited exposure to a lineup should “interrupt” decision making, whereby witnesses can only engage a relative strategy, thus leading to higher false positive responding given a target-absent lineup. Seventy-four adults viewed a 1-minute video that exposed them to an unknown target and subsequently viewed the lineup for a limited (2 s) or an unlimited amount of time. Although false positive rates were similar across conditions, accurate witnesses were more confident than inaccurate witnesses. Confidence was negatively correlated with response latency such that witnesses who took more time to make a decision were less confident in their decisions compared to witnesses who made more rapid decisions. Response latency did not differ for accurate and inaccurate witnesses. Limitations and suggestions for future research on the Two-Judgment Theory are discussed. 相似文献

Gillman, Howard, Mark Graber, and Keith Whittington. 2012 . American Constitutionalism: Volume I: Structures of Government . New York: Oxford University Press. Gillman, Howard, Mark Graber, and Keith Whittington. 2012 . American Constitutionalism: Volume II: Rights and Liberties . New York: Oxford University Press. This essay reviews Howard Gillman, Mark Graber, and Keith Whittington, American Constitutionalism: Volume I: Structures of Government (New York: Oxford University Press, 2012), and Howard Gillman, Mark Graber, and Keith Whittington, American Constitutionalism: Volume II: Rights and Liberties (New York: Oxford University Press, 2012). It defends developmental approaches in the study of US constitutional law. It explains how law has been studied in political science, illustrating how political development became part of the story. It outlines how American political development approaches work when applied to law, noting how studying law transforms these approaches. It notes the insights produced through the blending of American political development and constitutional law, explaining how these insights provide more leverage for understanding the role of courts as democratic institutions. The essay closes by discussing the promising directions these approaches suggest, defending their value beyond political science. 相似文献

We assessed perceptions of vulnerability and the desire for personal safety/self-defense (PS/SD) training among 67 female veterans receiving outpatient mental health treatment, primarily for post-traumatic stress disorder (PTSD) from sexual and/or physical trauma. Consistent with the literature on the impact of such training on nonclinical populations and on individuals with visual impairments, the results of this study indicate that traumatized female veterans believe that PS/SD training would be an effective and powerful addition to more traditional treatments for PTSD. Study participants indicated they believe such training would positively affect their sense of personal safety; promote increased competence in thwarting future assaults; improve their self-esteem, confidence, and assertiveness; and reduce avoidant and agoraphobic behaviors. These pilot results support the development of an adjunct intervention to augment current PTSD treatments for women veterans with histories of sexual and physical trauma. 相似文献

Preferential extraction of hydrocarbons from fire debris samples by solid phase microextraction 总被引:1,自引:0,他引:1
Headspace analysis by extraction/GC-MS is a common method of detecting volatile hydrocarbon accelerants in fire debris samples. Solid-phase microextraction was tested to determine if there is selective extraction of chemically distinct compounds. It was found that both the polydimethylsiloxane (PDMS) and Carboxen/PDMS solid phase microextraction fibers show preferential extraction of aliphatic or aromatic compounds from the headspace depending on fiber type and temperature. The Carboxen/PDMS fiber type showed particular (although not exclusive) selectivity for extraction of aromatic hydrocarbons. Other experimental considerations of SPME are noted. 相似文献

This paper builds on the views presented by the author at 'The Future of Forensic and Crime Scene Science Conference'. Forensic science has become an increasingly prominent area of science within the last 10 years. This increasing prominence together with popularity in the subject has seen the number of undergraduate students studying forensic science related courses at UK Universities increase rapidly in just 5 years and there are no short term signs of this trend reducing. In 2005, there were 450 courses with forensic in the title offered by higher education institutes. Although the forensic community has expressed its concern that job prospects for these students wishing to pursue careers as forensic scientists will be limited numbers of students undertaking science courses have still increased. The increase in students studying forensic science comes in an era of decreasing science numbers in higher education with the potential to produce high calibre science graduates with sought after skills in critical thinking, analysis, interpretation and communication. Technology has continued to advance at a similar pace providing those responsible for managing crime with a need and opportunity to identify and predict new and future applications of science and technology; not just in reducing and detecting crime but also in predicting how technology will be used by criminals in the future. There is therefore a need for forensic science users, providers and educators to identify the knowledge and skills required by forensic scientists and crime investigators of the future to ensure that technology continues to be used and applied to its full advantage. This provides universities an opportunity to contribute to the development of both the practice and practitioners of forensic science. This paper outlines the current issues facing universities in relation to forensic science and identifies their future role in providing high quality relevant courses for future forensic practitioners; developing current forensic practitioners through their participation in applied research, short courses, conferences and qualifications linked to professional practice; and supporting and developing the practice of forensic and crime scene science, through the identification, engagement and dissemination of pure and applied research. 相似文献

We investigated whether people need to believe in a just world in part because such a belief helps people to work toward long-term
goals and to do so in such a way that they are deserved. We assessed participants' long-term goal focus and also their commitment
to deserving their outcomes (via a psychopathy scale). In a second session, participants were then exposed to a victim whose
situation did or did not contradict a belief in a just world. When the victim's situation contradicted a belief in a just
world, the greater the participants' tendency to focus on long-term outcomes, the more they blamed the victim for her misfortune;
but this relation only occurred for participants with a strong commitment to deserving their outcomes (i.e., those low in
psychopathy). The results are consistent with our argument that, given the function of the belief in a just world proposed
in this article, people would have a greater need to preserve the belief (e.g., by blaming victims of injustice) the greater
their investment in long-term and deserved outcomes. 相似文献
