An experimental examination of alcohol consumption, alcohol expectancy, and self-blame on willingness to report a hypothetical rape.
This study experimentally examined the role of victim alcohol intoxication, and self-blame in perceiving and reporting rape to the police using a hypothetical interactive rape scenario. Participants (N = 79) were randomly assigned to consume alcohol (mean BAC = 0.07%) or tonic water before they engaged in the scenario. Alcohol expectancy was manipulated, and participant beliefs about the beverage they thought they had consumed and their feelings of intoxication were measured. Alcohol consumption and expectancy did not affect the likelihood that the nonconsensual intercourse depicted in the scenario was perceived and would be reported as rape. Participants with higher levels of self-blame were less likely to say they would report the hypothetical rape. Self-blame levels were higher for participants who believed they had consumed alcohol, and were associated with increased feelings of intoxication. The implications are discussed
Achieving more with less: A critical review of protocols for forensic investigation of sexual violence in low-resource environments
Sexual and gender based violence (SGBV) is notoriously difficult to investigate and prosecute. SGBV occurs in varied contexts and requires flexibility in the investigative approach in order to develop a strong evidence base to enable successful prosecutions. In this paper we focus on the need for innovation and development of training protocols for gathering testimonial and forensic evidence in SGBV cases, particularly in low resource environments, such as developing countries, displaced communities, and conflict and post-conflict societies. We discuss existing international guidelines that have been developed for improving the documentation and investigation of SGBV in these contexts, and argue there are significant gaps in the knowledge base that impede the effective implementation of such guidelines. In particular, collaborative research between academics, practitioners and NGOs is needed to address several priority areas. These include the development of programmes geared towards training non-specialist practitioners who work in low resource environments, as well as research programmes that evaluate the implementation of the programmes. This research will improve access to justice for victims and accountability for perpetrators of sexual violence
Re-refining the Measurement of Distress Intolerance
The current study aims to present a parsimonious measure of five factors of distress intolerance
as proposed by Zvolensky, Vujanovic, Bernstein, and Leyro (2010). Exploratory (n = 511) and
confirmatory (n = 157) factor analytic studies of items from five established measures of distress
intolerance suggest a 20-item measure representing five dimensions of distress intolerance
(uncertainty, ambiguity, physical discomfort, frustration, and negative emotion). A comparison of
latent factor models suggests that a bifactor model may present the best fit to the data, reflecting
the identification of a general factor of distress intolerance while also recognizing the
multidimensionality of the five group factors. The current findings suggest a parsimonious
measure of five factors of distress intolerance, though further research may consider method and
measurement biases and the convergent and discriminant validity of the subscales
Data_Sheet_3_Improving Time Estimation in Witness Memory.xlsx
The present study sought to determine whether witness memory for duration could be improved. In three studies, we examined the effects of unpacking (breaking an event into its component parts), anchoring (supplying participants with a reference duration), and summation (summing component estimates). Participants watched a video-recorded mock crime and provided duration estimates for components of the crime (e.g., casing the car, unlocking the door, etc.) and for the total crime. Results indicate that bias in estimated duration was less for the sum of the parts than it was for the overall duration estimate. Further, the sum of the individual parts did not equal the total estimate, even though all estimates were given in sequence. Summing the component parts could be a more successful intervention than anchoring or unpacking and is easy to employ with witnesses.</p

Selecting fillers on emotional appearance improves lineup identification accuracy
Mock witnesses sometimes report using criminal stereotypes to identify a face from a lineup, a tendency known as criminal face bias. Faces are perceived as criminal-looking if they appear angry. We tested whether matching the emotional appearance of the fillers to an angry suspect can reduce criminal face bias. In Study 1, mock witnesses (n = 226) viewed lineups in which the suspect had an angry, happy, or neutral expression, and we varied whether the fillers matched the expression. An additional group of participants (n = 59) rated the faces on criminal and emotional appearance. As predicted, mock witnesses tended to identify suspects who appeared angrier and more criminal-looking than the fillers. This tendency was reduced when the lineup fillers matched the emotional appearance of the suspect. Study 2 extended the results, testing whether the emotional appearance of the suspect and fillers affects recognition memory. Participants (n = 1,983) studied faces and took a lineup test in which the emotional appearance of the target and fillers was varied between subjects. Discrimination accuracy was enhanced when the fillers matched an angry target's emotional appearance. We conclude that lineup member emotional appearance plays a critical role in the psychology of lineup identification. The fillers should match an angry suspect's emotional appearance to improve lineup identification accuracy
