群体性事件集群行为的动员与组织机制

群体性事件指部分群众与当地党政部门或强势社会集团的对抗性冲突。是当下我国典型的集群行为。社会心理学对集群行为动员机制的研究主要包括群体相对剥夺、群体认同、群体(愤怒)情绪和群体效能; 对集群行为组织机制的研究主要包括速生规范、谣言和去个体化。其中, 群体愤怒和群体效能既属于动员机制, 同时又在组织机制中发挥作用。这些因素之间有待于进一步整合, 以期对现阶段我国社会频发的群体性事件的心理因素进行解释和探讨。     

Notes on Cultures of Violence, Cultures of Caring and Peace, and the Fulfillment of Basic Human Needs

Some conditions in the lives of children, adults, and groups can be construed as fulfilling universal human psychological needs. The constructive fulfillment of these basic needs promotes caring and positive, helpful relations; their frustration creates an inclination toward hostility and aggression. The article describes diverse influences that can lead to violence between individuals, groups, and societies, as well as ways to halt and prevent genocide, mass killing, and other intergroup violence, including terrorism, in part by fostering culture changes that promote harmony and peace. Ideally such culture change would involve healing from past wounds, the creation of positive (rather than destructive) ideologies, supportive communities, reconciliation and the creation of a shared collective memory, education that promotes peace, and the development of inclusive caring in children. The article also refers to work in Rwanda that aims to foster healing and reconciliation, in part by helping people understand the roots of violence and its implication for prevention. Societies and families that help to fulfill basic needs promote goodness as well as optimal human functioning—the continued growth and development of individuals.     

Mass Murder: An Analysis of Extreme Violence

Mass murder involves the slaughter of four or more victims by one or a few assailants within a single event, lasting but a few minutes or as long as several hours. More than just arbitrary, using this minimum body count—as opposed to a two- or three-victim threshold suggested by others (e.g., Ressler et al., 1988, Holmes and Holmes, 2001)—helps to distinguish multiple killing from homicide generally. Moreover, by restricting our attention to acts committed by one or a few offenders, our working definition of multiple homicide also excludes highly organized or institutionalized killings (e.g., war crimes and large-scale acts of political terrorism as well as certain acts of highly organized crime rings). Although state-sponsored killings are important in their own right, they may be better explained through the theories and methods of political science than criminology. Thus, for example, the definition of multiple homicide would include the crimes committed by Charles Manson and his followers, but not those of Hitler's Third Reich, or the 9/11 terrorists, despite some similarities in the operations of authority.     

Sensationalising sex offenders and sexual recidivism: Impact of the Serious Sex Offender Monitoring Act 2005 on media reportage

Differences in extent and nature of newspaper media reporting before and after the introduction of the Serious Sex Offender Monitoring Act 2005 in Victoria were investigated, critically exploring the interface between psychological, media and criminological disciplines. Forty‐three news items before the Act and 90 after the Act were analysed using a thematic and discursive framework. A significant increase in the number of items was found after the Act but other discursive and thematic findings were mixed. Several indicators of sensationalism such as headline size, tone, and theme did not differ between time frames, while there was a significant increase in the incidence of case‐based and high‐profile case reporting after the introduction of the Act. Hence, although the discourse and frames within which serious sex offenders are reported has remained similar over time, the introduction of the Act has dramatically impacted on the frequency of reporting in such cases. The findings are congruent with the extant literature on the newsworthiness of child sexual offending, indicating a need for media outlets to be more responsible in their reporting, and for legislators to enact legislation based upon empirical evidence.     

More Triviality

This paper uses the framework of Popper and Miller's work on axiom systems for conditional probabilities to explore Adams' thesis concerning the probabilities of conditionals. It is shown that even very weak axiom systems have only a very restricted set of models satisfying a natural generalisation of Adams' thesis, thereby casting severe doubt on the possibility of developing a non-Boolean semantics for conditionals consistent with it.     

Why do Alzheimer patients have difficulty with pronouns? Working memory, semantics, and reference in comprehension and production in Alzheimer's disease

Three experiments investigated the extent to which semantic and working-memory deficits contribute to Alzheimer patients' impairments in producing and comprehending referring expressions. In Experiment 1, the spontaneous speech of 11 patients with Alzheimer's disease (AD) contained a greater ratio of pronouns to full noun phrases than did the spontaneous speech produced by 9 healthy controls. Experiments 2 and 3 used a cross-modal naming methodology to compare reference comprehension in another group of 10 patients and 10 age-matched controls. In Experiment 2, patients were less sensitive than healthy controls to the grammatical information necessary for processing pronouns. In Experiment 3, patients were better able to remember referent information in short paragraphs when reference was maintained with full noun phrases rather than pronouns, but healthy controls showed the reverse pattern. Performance in all three experiments was linked to working memory performance but not to word finding difficulty. We discuss these findings in terms of a theory of reference processing, the Informational Load Hypothesis, which views referential impairments in AD as the consequence of normal discourse processing in the context of a working memory impairment.     

Accuracy of parents' reports of height and weight

The accuracy of parents' reports of their own height and weight and the height and weight of their obese children, who were about to enter a weight control program, was assessed. Measured height and weights of 146 mothers, 55 fathers, and 150 children who attended a screening session were compared to the heights and weights they had previously reported on a demographic questionnaire. Eighty-four percent of the reported weights were accurate within ±5 lbs.; 71% of the reported heights were accurate within ±1 in. Parents' reports of weight tended to underestimate actual weights, with the magnitude of underestimation greater for mothers than for fathers, while reported heights overestimated actual height, with the magnitude of overestimation greatest for fathers. Errors in the parents' reports of children's weight were related to the child's actual weight and body mass index (BMI), with substantial underestimation of actual weight in the heaviest decile of children in the sample.Preparation of this paper was supported in part by Grant HDMH12520-01 from the National Institute of Child Health and Human Development and Mental Health.

Male physical attractiveness in Britain and Malaysia: A cross-cultural study

Three purported cues to perceived male physical attractiveness are the waist-to-chest ratio (WCR), body mass index (BMI) and the waist-to-hip ratio (WHR). This study examined the relative contribution of each cue in several socio-economically distinct populations. Ninety-five female participants from Britain and Malaysia were asked to rate a set of images of real men with known WCR, BMI and WHR. The results showed clear differences along a gradient of socio-economic development. In urban settings, WCR was the primary component of attractiveness ratings, with BMI playing a smaller role and WHR not reaching significance. In the rural setting, BMI was the primary predictor of attractiveness, with WCR playing a more minor role and WHR not reaching significance. In general, urban participants were more reliant on body shape and chose a relatively slim figure with an ‘inverted triangle’ shape; rural participants were more reliant on body weight and chose a heavier figure with a less triangular shape. These findings are discussed in terms of evolutionary psychological explanations of mate selection and sociological theories that emphasise the effect of resource scarcity on preferences for body shapes and sizes.     

Science education,conceptual change and breaking with everyday experience

Science educators and those who investigate science learning have tended, for good reason, to focus their attention on students' conceptual development, Such a focus is, however, too narrow to provide full and proper understanding of the complexities of original science learning. Recently developmental cognitive psychologists have called on the work of postpositivistic philosophers of science, especially Thomas Kuhn, to bolster their research into conceptual development in science acquisition. What these psychologists have not recognized is that Kuhn's position is actually a derivative of Wittgenstein's methodological nominalism, a viewpoint far more favorable to behaviorism than cognitive psychology. After drawing out some of the consequences of this fact for the developmental cognitive psychologist program for studying science learning, we suggest our own radical alternative. Drawing on Floden, Buchmann and Schwille's idea of Breaking with Everyday Experience we propose an alternative notion of original science learning in terms of Alfred Schutz's modification of Williams James' many worlds thesis. The many worlds thesis will allow us to better understand students' difficulty in learning idealized worlds such as science, worlds that represent a discontinuous break with ordinary everyday practical experience.     

In Defense of the Responsibility to Protect

This essay responds to Esther Reed's recent critique of the Responsibility to Protect (R2P) principle in this journal. It argues that Reed fundamentally misunderstands and misrepresents R2P. Her critique of R2P would have served well as a critique of the earlier concept of humanitarian intervention had it been penned in the late 1990s. But most of the problems and dangers that Reed identifies are in reality the very problems and dangers that R2P seeks to overcome, and I suggest that it does overcome them quite successfully. R2P does not impose Western ideals on the rest of the world, weaken the legal restrictions on the use of force, or promote abusive interventionism. Rather, it offers a bold but carefully constructed framework that holds the promise of promoting the protection of vulnerable populations from mass atrocities.
