暴力视频游戏对个体亲社会性的影响：一项元分析

暴力视频游戏是一种新兴的娱乐媒介, 是指含有描绘个体试图对其他个体造成伤害等内容的视频游戏。亲社会性是人类区别于动物的重要特征, 包括在人际交往中个体所表现出的利他、助人等一切使他人受益的认知、情感和行为。本文采用元分析的方法整合国内外已有研究, 分析暴力视频游戏对玩家亲社会性影响的主效应, 并重点考察各调节变量在暴力视频游戏与亲社会性的关系中产生的作用。通过文献检索, 纳入符合要求的文献24篇, 包含63个效应值(effect size), 总样本量18554人。研究结果显示：暴力视频游戏与亲社会性总效应值显著, 但相关较弱(r = -0.10)。调节效应分析表明, 暴力视频游戏与亲社会性的关系受到被试性别、被试类型、被试年龄、测量类型与亲社会性测量指标的调节。未来研究可以进一步采用一般攻击模型与一般学习模型等理论模型指导暴力视频游戏对亲社会行为影响研究, 同时优化实证研究中测量亲社会性的实验范式, 并且需要重点考察个体差异对暴力视频游戏与亲社会性关系的影响。     

Schooling Bodies Through Physical Education: Insights from Social Epistemology and Curriculum History

Using mainly historical material fromAustralia, the paper seeks to understand earlyforms of school physical training, sport andmedical inspection as specialised means ofschooling bodies. The study adopts a socialepistemological perspective in seeking tounderstand the meaning-in-use of notions suchas physical training. It explores the socialconsequences of the practices carried out inthe name of physical training, particularly inrelation to shifts in the social regulation ofbodies over time from a mass, externalised, andcentralised form to a relatively moreindividualised, internalised and diffuse form.This focus on the body is of key importance fora social epistemological study of physicaleducation because it forces us to look closelyat the practices constituting physicaleducation.     

The lone gamer: Social exclusion predicts violent video game preferences and fuels aggressive inclinations in adolescent players

Violent video game playing has been linked to a wide range of negative outcomes, especially in adolescents. In the present research, we focused on a potential determinant of adolescents’ willingness to play violent video games: social exclusion. We also tested whether exclusion can predict increased aggressiveness following violent video game playing. In two experiments, we predicted that exclusion could increase adolescents’ preferences for violent video games and interact with violent game playing fostering adolescents’ aggressive inclinations. In Study 1, 121 adolescents (aged 10–18 years) were randomly assigned to a manipulation of social exclusion. Then, they evaluated the violent content of nine different video games (violent, nonviolent, or prosocial) and reported their willingness to play each presented video game. The results showed that excluded participants expressed a greater willingness to play violent games than nonviolent or prosocial games. No such effect was found for included participants. In Study 2, both inclusionary status and video game contents were manipulated. After a manipulation of inclusionary status, 113 adolescents (aged 11–16 years) were randomly assigned to play either a violent or a nonviolent video game. Then, they were given an opportunity to express their aggressive inclinations toward the excluders. Results showed that excluded participants who played a violent game displayed the highest level of aggressive inclinations than participants who were assigned to the other experimental conditions. Overall, these findings suggest that exclusion increases preferences for violent games and that the combination of exclusion and violent game playing fuels aggressive inclinations.

     

Observing behavior in a computer game.

Contingencies studied in lever-pressing procedures were incorporated into a popular computer game, "Star Trek," played by college students. One putative reinforcer, the opportunity to destroy Klingon invaders, was scheduled independently of responding according to a variable-time schedule that alternated unpredictably with equal periods of Klingon unavailability (mixed variable time, extinction schedule of reinforcement). Two commands ("observing responses") each produced stimuli that were either correlated or uncorrelated with the two components. In several variations of the basic game, an S-, or bad news, was not as reinforcing as an S+, or good news. In addition, in other conditions for the same subjects observing responses were not maintained better by bad news than by an uninformative stimulus. In both choices, more observing tended to be maintained by an S- for response-independent Klingons when its information could be (and was) used to advantage with respect to other types of reinforcement in the situation (Parts 1 and 2) than when the information could not be so used (Part 3). The findings favor the conditioned reinforcement hypothesis of observing behavior over the uncertainty-reduction hypothesis. This extends research to a more natural setting and to multialternative concurrent schedules of events of seemingly intrinsic value.     

Aspiration-Based and Reciprocity-Based Rules in Learning Dynamics for Symmetric Normal-Form Games

Psychologically based rules are important in human behavior and have the potential of explaining equilibrium selection and separatrix crossings to a payoff dominant equilibrium in coordination games. We show how a rule learning theory can easily accommodate behavioral rules such as aspiration-based experimentation and reciprocity-based cooperation and how to test for the significance of additional rules. We confront this enhanced rule learning model with experimental data on games with multiple equilibria and separatrix-crossing behavior. Maximum likelihood results do not support aspiration-based experimentation or anticipated reciprocity as significant explanatory factors, but do support a small propensity for non-aspiration-based experimentation by random belief and non-reciprocity-based cooperation.     

Power on the margins: A new place for intellectuals to be

This paper is concerned with rethinking the nature of social life in terms of how it appears — not to us academics at the centre of it, as consisting in a system, or a plurality of systems -but how it might appear from a position more in on the margins, at those moments when ordinary people must relate themselves to each other, unsystematically and practically. To do this, we must also rethink the nature of language and thought as possessing within these moments, a formative or creative character — for it must have the ability to create practical connections between aspects of people's lives, as required, on the spot. This is to privilege the role of rhetoric in these regions over that of logic. This also leads to a rethinking of ideology and power: as being to do with, not ideas, but the practical shaping (or not) — in moments when in practical communication with others — of collective, sharable forms of life. Where it is in such moments, in which different people meet each other in socially constructing their lives together, that political struggles are their most intense, and where ideology can be detected at work.     

Media Violence and Social Neuroscience: New Questions and New Opportunities

ABSTRACT— Decades of research have demonstrated that exposure to violence on television can cause increases in aggression. The recent emergence of violent video games has raised new questions regarding the effects of violent media. The General Aggression Model (GAM) predicts that exposure to violent media increases aggressive behavior through one of three primary pathways (arousal, cognitions, and affect). Past psychophysiological research has supported GAM but has been limited to examining arousal-related variables. Recent advances in social neuroscience have opened the door to investigations of exposure to violent media on cognitive and affective components and their neurocognitive underpinnings. Neuroscience tools have the potential to provide answers to the new questions posed by recent advances in media technology.     

Gender, Video Game Playing Habits and Visual Memory Tasks

The current research examined whether visuospatial recall of both abstract and common objects was related to gender or object familiarity. Seventy two undergraduates from a university in the Southern U.S. were asked to draw the Rey Complex Figure and a series of common objects from memory. A pilot sample of seventy three undergraduates had previously identified common objects as “male” “female” and “neutral” exemplars. Males were significantly better at drawing “male” and “neutral” exemplars whereas females were better at drawing “female” exemplars. Neither gender was significantly better at the Rey task. These results question whether males have an inherent advantage in visual memory. Results also found that experience with playing violent video games was associated with higher visual memory recall.
