Size Does Matter: The Effects of Gender on Perceptions of Dating Violence

Previous research has shown that people perceive intimate partner violence (IPV) as more serious in cases involving a male perpetrator and female victim versus other gender combinations. This study is the first to explore reasons for these differences. 181 undergraduates at a U.S. southeastern college rated one of four dating violence vignettes that varied by perpetrator and victim gender. Participants viewed male-on-female violence as more frightening primarily because males are stronger and bigger than female perpetrators. Physical differences were rated as significantly more important causes of fear than other personality/relationship dynamics. Because males are actually stronger and bigger than females, it appears that gendered perceptions of violence are based in real-world knowledge of gender differences, not merely gender stereotypes.     

Measurement of Preoperative Anxiety in Young Children: Self-report Versus Observer-rated

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used, observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS), and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy.     

VARIETIES OF RELIGIOUS COGNITION: A COMPUTATIONAL APPROACH TO SELF-UNDERSTANDING IN THREE MONOTHEIST CONTEXTS

This study considered representations of divine and human others in the self-understanding of monotheists from three religions. Self-understanding was conceptualized on the basis of semantic and episodic knowledge in narrative response data. Given the importance of social context in the formation of cognitive schemas, the project emphasized self-understanding in a comparative religious design. The sample included sixty nominated religious exemplars who responded to a structured interview. Schemas were subsequently mapped for Jews, Muslims, and Christians by comparison of self and other representations in a computational model known as latent semantic analysis (LSA). Findings indicated that representation of the divine is far removed from parents in cognitive schemas for all participants. Unlike Jews and Christians, Muslims appear to represent human others on the basis of self-understanding which principally references the divine. When considered in a computational semantic space, exemplars generally represent the self in a manner corresponding with divine and peer figures.     

Skulking around the dinosaur: Eliciting cues to children's deception via strategic disclosure of evidence

Research has shown that cues to deception are more salient as an effect of strategic use of evidence (SUE) during interviews. This study examined the feasibility of the SUE‐technique for eliciting cues to children's deception. Experiment 1 investigated verbal cues to deception as a function of early vs. late disclosure of evidence. Eighty‐four children (12–14 years) either guilty or innocent of a mock crime were interviewed. As predicted, deceptive statements were significantly more inconsistent with the evidence than truthful statements, and this was more pronounced as a function of late compared to early disclosure of evidence. In Experiment 2, adult observers (N = 168) made veracity assessments of the videotaped statements. Observers in the late disclosure condition achieved an accuracy rate higher than chance (63.1%), whereas accuracy rates in the early disclosure condition were at chance level (56%). Accuracy rates were significantly higher for truthful (70.2%), than deceptive statements (48.8%). Copyright © 2009 John Wiley & Sons, Ltd.     

Liberty to Decide on Dual Use Biomedical Research: An Acknowledged Necessity

Humanity entered the twenty-first century with revolutionary achievements in biomedical research. At the same time multiple “dual-use” results have been published. The battle against infectious diseases is meeting new challenges, with newly emerging and re-emerging infections. Both natural disaster epidemics, such as SARS, avian influenza, haemorrhagic fevers, XDR and MDR tuberculosis and many others, and the possibility of intentional mis-use, such as letters containing anthrax spores in USA, 2001, have raised awareness of the real threats. Many great men, including Goethe, Spinoza, J.B. Shaw, Fr. Engels, J.F. Kennedy and others, have recognized that liberty is also a responsibility. That is why the liberty to decide now represents an acknowledged necessity: biomedical research should be supported, conducted and published with appropriate measures to prevent potential “dual use”. Biomedical scientists should work according to the ethical principles of their Code of Conduct, an analogue of Hippocrates Oath of doctors; and they should inform government, society and their juniors about the problem. National science consulting boards of experts should be created to prepare guidelines and control the problem at state level. An international board should develop minimum standards to be applicable by each country. Bio-preparedness is considered another key-measure.     

The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

Multiple channel exposure therapy for women with PTSD and comorbid panic attacks

Multiple channel exposure therapy (M-CET; Falsetti & Resnick, 2000) was developed to treat posttraumatic stress disorder (PTSD) with comorbid panic attacks and can be administered in a group format. In addition to being a cost-effective way to provide treatment, group treatment for those with PTSD has been proposed as potentially very beneficial for addressing feelings of shame related to the traumatic event as well as social isolation in general (Foy et al., 2000). Previous studies of M-CET indicate that it may be effective for the treatment of PTSD with comorbid panic attacks (Falsetti et al., 2001, 2003, 2005). The authors examine the relationship of PTSD and panic symptoms pre- and posttreatment and present 6-month follow-up data on the long-term effectiveness of M-CET.     

Familiarity breeds distortion: the effects of media exposure on false reports concerning media coverage of the terrorist attacks in london on 7 July 2005

The present experiment investigated whether increased media exposure could lead to an increase in memory distortions regarding a traumatic public event: the explosion of the No. 30 bus in Tavistock Square, London on 7 July 2005. A total of 150 Swedish and 150 UK participants completed a series of questionnaires about their memory of either (i) the aftermath of the explosion, (ii) a non-existent computerised reconstruction of the moment of the explosion, or (iii) non-existent closed circuit television footage of the moment of the explosion. In line with the availability heuristic, U.K. participants were more likely than Swedish participants to claim to have seen all three types of footage. Furthermore, a subsample of U.K. participants who appeared to have developed false "memories" of seeing the No. 30 bus explode scored significantly higher on measures of dissociation and fantasy proneness than participants who did not develop false "memories". This experiment provides further support for the role of imaginative processes in the development of false memories.     

Methylphenidate amplifies long-term plasticity in the hippocampus via noradrenergic mechanisms

Methylphenidate treatment is used for Attention Deficit Hyperactivity Disorder and can improve learning and memory. Previously, improvements were considered a by-product of increased attention; however, we hypothesize that methylphenidate directly alters mechanisms underlying learning and memory, and therefore examined its effects on hippocampal long-term potentiation and long-term depression. Methylphenidate enhanced both mechanisms in the absence of presynaptic changes and in a noradrenalin beta-receptor-dependent manner. These findings can explain both the improved learning and memory and decreased learning selectivity found with methylphenidate treatment and constitute the first demonstration of direct actions of methylphenidate on mechanisms implicated in cognition.     

Loving-kindness meditation increases social connectedness

The need for social connection is a fundamental human motive, and it is increasingly clear that feeling socially connected confers mental and physical health benefits. However, in many cultures, societal changes are leading to growing social distrust and alienation. Can feelings of social connection and positivity toward others be increased? Is it possible to self-generate these feelings? In this study, the authors used a brief loving-kindness meditation exercise to examine whether social connection could be created toward strangers in a controlled laboratory context. Compared with a closely matched control task, even just a few minutes of loving-kindness meditation increased feelings of social connection and positivity toward novel individuals on both explicit and implicit levels. These results suggest that this easily implemented technique may help to increase positive social emotions and decrease social isolation.
