Investigating the implicit theories of rape‐prone men using an interpretative bias task

Purpose. Ward (2000) has hypothesized that sexual offenders hold offence supportive implicit theories (ITs) or schemata that function to facilitate or maintain offending behaviour. The present research aimed to determine whether rape‐prone men hold the same offence supportive ITs as those that have been identified in rapists. Method. This study adopted both an explicit measure of ITs and also an implicit measure of ITs (an interpretative bias task). In the implicit task, participants viewed ambiguous stimuli (one‐sentence statements) that may be interpreted in either a rape‐supportive manner, or a non‐rape‐supportive manner. Participant's interpretation of the stimuli was assessed via a memory recognition task. We predicted that men higher on proclivity to rape – who presumably hold strong mental representations of rape‐supportive themes – would be more likely to interpret stimuli in a rape‐supportive manner relative to non‐rape‐supportive stimuli compared to men lower on rape proclivity. Results. Using multiple regression to determine the relative contributions of both explicit and implicit measures for predicting rape proclivity, we found that only the explicit, self‐report questionnaire and one of the ITs, ‘women are sex objects’ (as measured by the interpretative bias task), was significantly related to a person's rape proclivity score. Conclusions. This result indicates that rape‐prone men may not share the same beliefs as convicted rapists, which could be a key difference between men at risk of offending, and those who have been convicted of a sexual offence.     

Eyewitness Identifications by Older and Younger Adults: A Meta-Analysis and Discussion

The current meta-analysis compared younger and older adult eyewitness identification accuracy and includes analyses designed to determine what witness and event factors might moderate any differences found. Results showed that, regardless of lineup type and perpetrator age, older eyewitnesses are reliably worse at making correct lineup decisions than younger eyewitnesses whether they are identifying perpetrators or rejecting perpetrator-absent lineups. Discussion of possible causes for this difference in identification accuracy is drawn from cognitive and social psychology literatures, and possible implications for future research and public policy are put forth.     

The relationship of violent fathers, posttraumatically stressed mothers and symptomatic children in a preschool-age inner-city pediatrics clinic sample

This study aims to understand if greater severity of maternal posttraumatic stress symptoms (PTSS), related to maternal report of interpersonal violence, mediates the effects of such violence on (a) child PTSS as well as on (b) child externalizing and internalizing symptoms. Study participants were mothers (N = 77) and children 18 to 48 months recruited from community pediatric clinics. Data were analyzed continuously via bivariate correlations and then multiple linear regression. Post hoc Sobel tests were performed to confirm mediation. Paternal violence accounted for 15% of the variance of child PTSS on the PCIP-OR (β = .39, p ≤ .001). While the child's father being violent significantly predicts child PTSS related to domestic violence, as mentioned, when maternal PTSS is included in the multiple regression model, father's being violent becomes less significant, while maternal PTSS remains strongly predictive. Sobel tests confirmed that maternal PTSS severity mediated effects of paternal violence on clinician-assessed child PTSS as well as on maternal report of child externalizing and internalizing symptoms. When presented with a preschool-aged child who is brought to consultation for behavioral difficulties, dysregulated aggression, and/or unexplained fears, clinicians should evaluate maternal psychological functioning as well as assess and treat the effects of interpersonal violence, which otherwise may be avoided during the consultation.     

Birds of a Feather Fight Together: Status-Enhancing Violence,Social Distance and the Emergence of Homogenous Gangs

Objectives

This study proposes a theoretical framework for understanding two empirical findings from gang research: (1) gangs are generally racially homogenous, even in heterogeneous environments, and (2) gang violence tends to be intra-racial. We draw from the extensive literature on street gangs as well as from research on group formation and status-enhancing behavior to develop a theoretical model of gang formation.

Methods

Using game theory, we model the simultaneous decisions of individuals to commit status-enhancing acts of violence and to seek protection by joining a gang. We then conduct computer simulations to examine the resulting patterns of violence and gang composition.

Results

We demonstrate that as long as some social distance exists between racial groups in a community, gang violence will be intra-racial and gangs will be homogenous. We find that our results are robust to a number of simple variations of the model and allow us to generate several hypotheses about the nature of gang formation and patterns of violence.

Conclusions

When violence is motivated by socially constructed rewards, socially closer targets are likely to yield greater rewards. In such a system, individuals must reduce their likelihood of victimization by entering a social contract of non-violence (i.e. gang membership) with individuals who might view them as status-enhancing targets (i.e. socially close individuals). The result is that gangs are made up of socially close individuals interested in attacking other socially close individuals. Therefore, gangs tend to be racially homogenous and violence is overwhelmingly intra-racial.

     

Mighty Morphin’ age progression: how artist,age range,and morphing influences the similarity of forensic age progressions to target individuals

When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.     

Ethnic Elites and Rituals of Provocation: Politicians,Pastors, and Paramilitaries in Northern Ireland

ABSTRACT

Prominent theories of ethnic conflict argue that instrumental ethnic elites incite violence in order to promote their own power. Yet this approach focuses primarily on political leaders and ignores other ethnic elites, meaning that we know little about how other influential actors think about provocation. In this paper, I present novel data from Northern Ireland on diverse elite attitudes toward polarising Protestant parades with a long history of sparking ethnic violence. Using original surveys of Protestant elected officials and clergy as well as interviews with ex-paramilitaries, this paper demonstrates that these elite groups have different, often competing, interests and opinions regarding contested parades: while politicians tend to support provocative parades, the others do not. By addressing elite actors that are often ignored, I present a more nuanced picture of elite-mass relations and ethnic mobilisation in conflict.     

Kenya: succession,customary law

This article seeks to explore the idea that a health care professional who becomes aware that a patient has a genetic linked disorder should in some circumstances owe a duty to inform blood relatives of that fact, and that failure to so inform should be redressed through the law of negligence. This is a contention which has appeared in medical literature ¹ 1 Lucassen, A. (2007), Should families own genetic information? Yes, BMJ, 335(July), p. 22. and been the subject of litigation in American jurisprudence. ² 2 Pate v Threlkel (1995) 661 S0 2d (SC Florida); Safer v Puck (1996) 677 2d 1188 (SC, NJ). Given that medical researchers have identified the genetic causes of many human diseases through more sophisticated methods of DNA sequencing, and have confirmed the hereditary nature of many of these conditions, the disclosure of screening results is a serious and contentious issue. This is particularly so given the increasing importance of preventative medicine as a means of dealing with disease. ³ 3 See Seigler, M. (1982) Confidentiality in medicine – a decrepit concept, N‐Engl J Med, 307, p. 1518, where he refers to medicine expanding ‘from a narrow, disease‐based model to a model that encompasses psychological, social and economic problems’. Also note the increasing emphasis now given to the prevention of diabetes and obesity through lifestyle education. The article suggests, by reference to ethical discourse, and particularly Levinas' theory on responsibility, ⁴ 4 See Levinas, E. (1961) Totality and Infinity, trans. A. Lingus 1969 (Pittsburgh: Duquesne University Press); Levinas, E. (1974) Otherwise Than Being, or Beyond Essence, trans. A. Lingus 1981 (The Hague: Martinus Mijhoff). that health professionals do owe a duty of care to a patient's relatives, but that this duty may be discharged in ways which do not necessarily involve the disclosure of the information to those parties, and that it is only in certain, specified circumstances that a duty to disclose the information exists.     

How Can We Help Witnesses to Remember More? It’s an (Eyes) Open and Shut Case

Five experiments tested the idea that instructing a witness to close their eyes during retrieval might increase retrieval success. In Experiment 1 participants watched a video, before a cued-recall test for which they were either instructed to close their eyes, or received no-instructions. Eye-closure led to an increase in correct cued-recall, with no increase in incorrect responses. Experiments 2-5 sought to test the generality of this effect over variations in study material (video or live interaction), test format (cued- or free-recall) and information modality (visual or auditory details recalled). Overall, eye-closure increased recall of both visual detail and auditory details, with no accompanying increase in recall of false details. Collectively, these data convincingly demonstrate the benefits of eye-closure as an aid to retrieval, and offer insight into why hypnosis, which usually involves eye-closure, may facilitate eyewitness recall.
