Aggression in the Laboratory: Problems with the Validity of the Modified Taylor Competitive Reaction Time Test as a Measure of Aggression in Media Violence Studies

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity.     

Body size and body esteem in women: The mediating role of possible self expectancy

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.     

The relative contributions of subjective and objective measures of body shape and size to body image and disordered eating in women

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR.     

Tomorrow's consumer — the shifting balance of power

What are the prospects for consumerism? Often despised as self‐indulgent, consumers are frequently motivated by altruism and their needs to express their identity, to build relationships, to obtain fulfilment and even to find a substitute for religion. Mass‐customisation is producing fundamental change, revolutionising attitudes to choice, with a key role for agents (human and online) in helping people choose. Consumer power will grow and brands will be under pressure from rising consumer expectations. While retailers fight back with targeted marketing and special offers, brands will need to serve consumer needs as much as suppliers. Online shopping could transform consumer behaviour, driven by cost saving and convenience and spurred on by competition. Will retailers protect their traditional channels or go online because they are afraid not to? ‘Etailing’ will need to create consumer trust, so regulation will be critical, possibly leading to legal responsibilities for quality on Internet service providers (ISPs) and portals and with systems to help new entrants build a track record of reliability, thereby increasing competition, choice and consumer power.

男性身体意象失调:大众媒体的影响及作用机制

近年来,男性身体意象失调越来越普遍,大众媒体被认为是一种重要的影响因素。大量研究证实了媒体对男性身体意象的消极影响,主要表现在对身体意象的认知、情绪情感和行为调控等方面。研究者基于社会文化理论提出三重影响模型(Thompson,Heinberg,Altabe,Tantleff-Dunn,1999),用以解释媒体影响男性身体意象的作用机制。该模型假设社会文化因素,即家庭、同伴、媒体是身体意象失调的三个最初影响源;外貌比较和"瘦理想"或"肌肉理想"内化是社会文化和身体意象失调之间的中介变量。未来研究应关注被试群体的多样化,将实验室研究和纵向研究相结合,并考虑其他变量的影响作用,对三重影响模型进行丰富和拓展,同时运用脑科学技术探究其神经机制。此外,还应从干预的角度展开研究。     

Social relations in crowds: Recognition,validation and solidarity

Social identity research on crowds demonstrates how cognitive self-definition as a crowd member results in conformity to identity-relevant norms. Rather less research has addressed the social-relational changes within a crowd and how these impact collective experience positively. The present study investigates these processes at a month-long mass gathering in India. Analysis of 37 interviews with participants attending the annual Magh Mela pilgrimage evidences the concept of shared identity as underpinning their understanding of this mass gathering. Moreover, a theoretically derived thematic analysis of these interviews shows the value of the analytic concepts of recognition, validation, and solidarity in illuminating the ways in which social relations in the crowd were experienced and contributed to the experience of the event. Through exploring the multi-dimensional nature of relational connectedness in crowds we contribute to an understanding of crowd experience and group processes.     

Fear and its vicissitudes

Abstract

The USA has been a changed society since 9/11: the Zeitgeist either has a background of low-level angst, or when an attack occurs or a threat is sounded, the fear peaks and comes to the foreground for a time. Perhaps nothing demonstrates the degree to which fear permeates contemporary culture more than the continual presence of the measures the USA takes to be safe: airport security, the Patriot Act, the mining of formerly private information by the government, to name but a few. Can we account for the pervasive nature of fear solely by the devastating and deadly attacks 15 years ago, unspeakably horrifying though they were? This paper will explore this omnipresent fear in contemporary American culture from a psychoanalytic perspective, and in so doing hopes to shed light on the nature of that fear, why it is so persistent despite 15 years without any sequels, and what the consequences of that fear are for the American way of life. The discussion will be rounded out by linking this pervasive fear to the violence that is endemic to our age.     

Preventive Wars, Just War Principles, and the United Nations

This paper explores the question of whether the United Nations should engage in preventive military actions. Correlatively, it asks whether UN preventive military actions could satisfy just war principles. Rather than from the standpoint of the individual nation state, the ethics of preventive war is discussed from the standpoint of the UN. For the sake of brevity, only the legitimate authority, just cause, last resort, and proportionality principles are considered. Since there has been disagreement about the specific content of these principles, a third question also is explored: How should they be formulated? Moreover, these questions are addressed in the context of a particular issue: the goals of the non-proliferation and the abolition of weapons of mass destruction.     

The analyst: His professional novel1

The psychoanalyst needs to be in touch with a community of colleagues; he needs to feel part of a group with which he can share cognitive tension and therapeutic knowledge. Yet group ties are an aspect we analysts seldom discuss. The author defi nes the analyst's ‘professional novel’ as the emotional vicissitudes with the group that have marked the professional itinerary of every analyst; his relationship with institutions and with theories, and the emotional nuance of these relationships. The analyst's professional novel is the narrative elaboration of his professional autobiography. It is capable of transforming the individual's need to belong and the paths of identifi cation and deidentifi cation. Experience of the oedipal confi guration allows the analyst to begin psychic work aimed at gaining spaces of separateness in his relationship with the group. This passage is marked by the work on mourning that separation involves, but also of mourning implicit in the awareness of the representative limits of our theories. Right from the start of analysis, the patient observes the emotional nuance of the analyst's connection to his group and theories; the patient notices how much this connection is governed by rigid needs to belong, and how much freedom of thought and exploration it allows the analyst. The author uses clinical examples to illustrate these hypotheses.     

The effects of body mass index and waist-to-hip ratio on ratings of female attractiveness, fecundity, and health

This paper examines the effects of body mass index (BMI) and waist-to-hip ratio (WHR) on people’s perceptions of female attractiveness and fecundity. One hundred and two participants (51 females) were asked to rate 18 line drawings, varying across three BMI and six WHR levels, on seven different attributes (‘healthy’, ‘fertile’, ‘youthful’, ‘intelligent’, ‘nurturing’, ‘flirty’, and ‘attractive’). Line drawings manipulated arm and leg thickness while keeping torso WHR consistent, thus unconfounding previously confounded variables. The data were analysed through a doubly multivariate analysis of variance. Effect sizes were larger for BMI than for WHR. Figures of average weight and a WHR of 0.7 were rated as most attractive and healthy. Overall, the results demonstrate that the effects of BMI and WHR on perceptions of attractiveness and fecundity are interdependent and should be studied concurrently rather than in isolation.
