媒体暴力与攻击性：社会认知神经科学视角

媒体暴力与攻击性之间是否存在因果关系一直存在争论。随着社会认知神经科学的兴起,研究者可以通过ERP和fMRI等技术进一步对媒体暴力与攻击性的内在联系进行研究。本文首先分析媒体暴力与攻击性在社会认知神经科学领域取得的最新研究成果,特别是ERP和fMRI成果。其次,指出该领域研究中应该注意被试、工具以及研究方法的选择。最后,未来可以从不同年龄段、不同媒体暴力形式、以催化剂模型为理论背景等多方面进行社会认知神经机制的研究,另外,构建媒体暴力影响攻击性的认知神经模型也是未来一个有价值的研究方向。     

Social strategies in self-deception

How do people deceive themselves? I argue that although self-deception tends to be conceptualized as something that happens ‘within an individual’, it can also be a process that is distributed across the social context of a self-deceiver. In this paper I will, first, conceptually distinguish different strategies of such ‘social self-deception’. Second, I will incorporate these into the two main conceptualizations of self-deception: intentionalism and deflationism. Finally, I will show how the proposed re-conceptualization of self-deception can be beneficial to conceptual, moral and empirical research.     

Tele‐analysis: the use of media technology in psychotherapy and its impact on the therapeutic relationship

A growing number of approaches in psychotherapy make use of internet‐ and other media‐based interactions. This paper discusses the impact on the therapist‐client relationship of using media technology and gives an overview of the current state of the debate. It is suggested that the technical conditions of internet‐based interactions produce new forms of social relationships that differ significantly from face‐to‐face‐interactions and that unconscious, nonverbal cues get lost. Research on the therapeutic interaction making use of ‘discourse linguistic’ methods is presented. The loss of nonverbal cues has implications for psychotherapy in general and especially for the treatment of patients who have difficulties relying on a secure therapeutic relationship. Emotional security in interactional relationships is transmitted to a much greater extent by nonverbal cues than by verbal content; psychoanalytic methods are specialized to refer to this level of interaction. Two alternative scenarios are discussed based on the psychoanalytic theories of Winnicott and Lacan: the risk of an illusionary, idealized image of the other and the possibility that cyberspace can be used for psychological development as a transitional space.     

The Backyard Politics of Attitudes Toward Immigration

Using two survey experiments, I reconsider the role that the racialized physical traits and level of assimilation of salient immigrants play in shaping attitudes toward immigration. In the first experiment, a nationwide sample of 767 White, non‐Latino adults was exposed to a story about a family of undocumented immigrants living in the Unites States who were at risk of deportation. Subjects were randomly assigned to view a version of the story in which the immigrants were depicted with light skin and stereotypically Eurocentric features, or dark skin and stereotypically Afrocentric features, and their level of assimilation to mainstream American culture was suggested to be high or low. Similar to previous research, the study's results show that assimilation has a direct effect on attitudes toward immigration. Yet in contrast to previous studies, the racialized physical traits proved to be a much more important factor in shaping attitudes toward immigration than previously demonstrated. The role of an immigrant's racialized physical traits was replicated in a second survey experiment of 902 White, non‐Latino adults. Overall, the findings shed new light on how media depictions of immigrants are affecting immigration attitudes, as well as the nuanced ways that race continues to shape public opinion in the United States today.     

Photography and Social Media Use in Community‐Based Participatory Research with Youth: Ethical Considerations

Community‐based participatory researchers increasingly incorporate photography and social media into their work. Despite its relative infancy, social media has created a powerful network that allows individuals to convey messages quickly to a widespread audience. In addition to its potential benefits, the use of social media in research also carries risk, given the fast pace of exchanges, sharing of personal images and ideas in high accessibility, low privacy contexts and continually shifting options and upgrades. This article contributes to the literature examining ethical considerations for photography and social media use in community‐based participatory research. We describe three key ethical dilemmas that we encountered during our participatory photography project with Latina/o youth: (a) use and content of images and risk; (b) incentives and coercion; and (c) social media activity and confidentiality. We provide our responses to these challenges, contextualized in theory and practice, and share lessons learned. We raise the question of how to contend with cultural shifts in boundaries and privacy. We propose that evaluating participant vulnerability versus potential empowerment may be more fitting than the standard approach of assessing risks and benefits. Finally, we recommend upholding the principles of participatory research by co‐producing ethical practices with one's participants.     

Media framing of proposed nuclear reactors: An analysis of print media

Nuclear energy has received substantial recent attention, marketed as a ‘green’ solution to global climate change (GCC) with calls for new reactors. However, considerable debate exists about whether it represents a viable solution to GCC. Given the complexity and urgency of the issue, a full and balanced debate is desirable. Since media play an important role in shaping public perception, we examined print media coverage of proposed reactors in Georgia—one site in the southeastern United States, which has been the focus of such proposals. We analysed the content of editorials and news articles from two local newspapers—the Augusta Chronicle and Atlanta Journal‐Constitution. The former exclusively published pro‐nuclear opinion pieces whereas the latter published a mix of pro‐ and anti‐nuclear opinions. The majority of news articles in both newspapers generally presented balanced arguments. Pro‐ and anti‐nuclear arguments most often reflected economic and environmental benefits and risks, whereas informational text primarily detailed regulatory processes and financing. Findings suggested that informational text was not necessarily ‘neutral’, sometimes masking covert pro‐ and anti‐nuclear content. Implications for how findings might shape public opinion and strategies for shaping media and extending public deliberation are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

The impact of advertisements featuring ultra‐thin or average‐size models on women with a history of eating disorders

Previous research demonstrates that exposure to ultra‐thin media models leads to increased body image concerns amongst women (Groesz, Levine, & Murnen, 2002 ). There is emerging evidence that attractive, average‐size models do not have this negative effect and can be effective in advertising (e.g. Halliwell & Dittmar, 2004 ). The present study investigates these factors amongst women with a history of eating disorders. Participants either viewed advertisements featuring ultra‐thin, average‐size or control images. Immediately after exposure, they reported their body‐focused anxiety and rated the effectiveness of the advertisements. Whereas exposure to ultra‐thin models did not lead to increased body‐focused anxiety, exposure to average‐size models produced a relief effect, whereby women reported lower levels of body‐focused anxiety. Advertisements featuring ultra‐thin and average‐size models were equally effective. The results suggest that average‐size, attractive models could be used effectively in advertising, which may help to relieve body image concerns amongst these women.

Sin and bioethics: why a liturgical anthropology is foundational.

The project of articulating a coherent, canonical, content-full, secular morality-cum-bioethics fails, because it does not acknowledge sin, which is to say, it does not acknowledge the centrality of holiness, which is essential to a non-distorted understanding of human existence and of morality. Secular morality cannot establish a particular moral content, the harmony of the good and the right, or the necessary precedence of morality over prudence, because such is possible only in terms of an ultimate point of reference: God. The necessity of a rightly ordered appreciation of God places centrally the focus on holiness and the avoidance of sin. Because the cardinal relationship of creatures to their Creator is worship, and because the cardinal corporate act of human worship is the Liturgy, morality in general and bioethics in particular can be understood in terms of the conditions necessary, so as worthily to enter into Eucharistic liturgical participation. Morality can be summed up in terms of the requirements of ritual purity. A liturgical anthropology is foundational to an account of the content-full morality and bioethics that should bind humans, since humans are first and foremost creatures obliged to join in rightly ordered worship of their Creator. When humans worship correctly, when they avoid sin and pursue holiness, they participate in restoring created reality.     

Media violence exposure in aggressive and control adolescents: differences in self‐ and parent‐reported exposure to violence on television and in video games

The purpose of present study was to investigate differences in media violence exposure between groups of adolescents with and without Disruptive Behavior Disorders with Aggressive Features, using a case‐controlled design and multimethod assessment. Samples of 27 adolescents aged 13‐17 with Disruptive Behavior Disorder with Aggressive Features and 27 age‐gender‐IQ matched controls completed a semistructured interview about exposure to violence on television and video games; parents completed a corresponding questionnaire measure. Moderate intercorrelations were found between most self‐ and parent‐report television and video game violence exposure measures. Compared to control adolescents, adolescents with Disruptive Behavior Disorder with Aggressive Features had higher aggregate media violence exposure, higher exposure to video game violence, and higher parent‐reported exposure to television violence. Results show that adolescents and parents agree about the adolescent's level of media violence exposure, that exposure to violence on television tends to be accompanied by exposure to violence in video games, and that the association between media violence exposure and Disruptive Behavior Disorder with Aggressive Features is not due to a spurious effect of gender or IQ.

SIGNALING STATIC: ARTISTIC,RELIGIOUS, AND SCIENTIFIC TRUTHS IN A RELATIONAL ONTOLOGY

Abstract. In this essay I point toward the difficulties inherent in ontological objectivity and seek to restore our truth claims to validity through a relational ontology and the dynamic of coimplication in signals and noise. Theological examination of art and science points toward similarities between art, religion, and science. All three have often focused upon a “metaphysics of presence,” the desire for absolute presence of the object (the signified, the divine, the natural object). If we accept a relational ontology, however, we must accept that the revelation of presence is always simultaneously a concealment. This helps explain technoscientific achievement without recourse to a philosophically flawed objectivity. Twentieth‐century information theory shows the impossibility of a “pure signal.” By accepting that signal and noise are permanently interconnected, we begin to see how noise makes signal possible and even how noise becomes signal (allowing the discovery of novel facts). Information theory thus underscores important similarities and leads toward new approaches in aesthetics, Christian theology, and scientific research. By comparing art, religion, and science, I argue that rejecting a metaphysics of presence without rejecting presence itself allows human beings to know the world. Although religion, science, and art often seek the absolute presence of their objects, they function better without.
