Violent and nonviolent video games produce opposing effects on aggressive and prosocial outcomes

Experimental studies routinely show that participants who play a violent game are more aggressive immediately following game play than participants who play a nonviolent game. The underlying assumption is that nonviolent games have no effect on aggression, whereas violent games increase it. The current studies demonstrate that, although violent game exposure increases aggression, nonviolent video game exposure decreases aggressive thoughts and feelings (Exp 1) and aggressive behavior (Exp 2). When participants assessed after a delay were compared to those measured immediately following game play, violent game players showed decreased aggressive thoughts, feelings and behavior, whereas nonviolent game players showed increases in these outcomes. Experiment 3 extended these findings by showing that exposure to nonviolent puzzle-solving games with no expressly prosocial content increases prosocial thoughts, relative to both violent game exposure and, on some measures, a no-game control condition. Implications of these findings for models of media effects are discussed.     

Forewarned is forearmed: Conserving self-control strength to resist social influence

Recent research has shown that resisting persuasion involves active self-regulation. Resisting an influence attempt consumes self-regulatory resources, and in a state of self-regulatory resource depletion, people become more susceptible to (unwanted) influence attempts. However, the present studies show that a forewarning of an impending influence attempt prompts depleted individuals to conserve what is left of their regulatory resources and thus promotes self-regulatory efficiency. As a result, when these individuals are subsequently confronted with a persuasive request, they comply less (Experiments 1 and 3), and generate more counterarguments (Experiment 2) than their depleted counterparts who were not forewarned and thus did not conserve their resources, and they are as able as non-depleted participants to resist persuasion.     

Longer is better

The longer something is thought to exist, the better it is evaluated. In Study 1, participants preferred an existing university requirement over an alternative; this pattern was more pronounced when the existing requirement was said to be in place for a longer period of time. In Study 2, participants rated acupuncture more favorably as a function of how old the practice was described. Aesthetic judgments of art (Study 3) and nature (Study 4) were also positively affected by time in existence, as were gustatory evaluations of an edible consumer good (Study 5). Features of the research designs argue against mere exposure, loss aversion, and rational inference as explanations for these findings. Instead, time in existence seems to operate as a heuristic; longer means better.     

Exposure to media and theory-of-mind development in preschoolers

Exposure to different forms of narrative media may influence children's development of theory-of-mind. Because engagement with fictional narratives provides one with information about the social world, and possibly draws upon theory-of-mind processes during comprehension, exposure to storybooks, movies, and television may influence theory-of-mind development. We examined 4–6 year-olds’ inferred exposure to children's literature, television, and film, using an objective measure that controls for socially desirable responding. Theory-of-mind was assessed using a battery of five tasks. Controlling for age, gender, vocabulary, and parental income, inferred exposure to children's storybooks predicted theory-of-mind abilities. Inferred exposure to children's movies also predicted theory-of-mind development, but inferred exposure to children's television did not.

听障儿童外部情绪理解研究

通过自编的外部情绪理解问卷,考察了听障儿童表情识别、情绪情景识别和提示物理解等外部情绪理解三个成分的发展状况。结果表明:(1)听力障碍儿童在外部情绪整体理解、表情识别、情绪情景识别和提示物理解四方面的得分都显著低于普通儿童;(2)不同年级听力障碍儿童的外部情绪理解、表情识别、情绪情景识别和提示物理解四方面得分存在显著差异,不同性别听力障碍儿童外部情绪理解差异不显著;年级和性别的交互作用显著;(3)父母听力状况不同的听障儿童,其外部情绪理解水平差异显著。DD儿童的外部情绪整体理解、表情识别和情绪情景识别得分显著高于DH儿童。     

Might an overweight waitress make you eat more? How the body type of others is sufficient to alter our food consumption

This paper investigates how people's food choices can be shaped by the body type of others around them. Using a professionally constructed obesity prosthesis, we show that the body type of a (confederate) server in a taste test study was sufficient to alter both the quantity (Experiment 1) and specific choices (Experiment 2) participants made but that chronic dieters and non-dieters exhibited opposite effects. While non-dieters ate more snacks when the server was thin, dieters ate more when the server was heavy. Dieters were also more persuaded by a heavy (vs. a thin) server, choosing both a healthy and unhealthy snack more often when she recommended it to them. We suggest these results may be attributable to identification with the server.     

Uniforms affect the accuracy of children's eyewitness identification decisions

A substantial proportion of line‐up identifications involving child eyewitnesses in the UK are conducted by police officers wearing uniform. This study examined the possibility that wearing a uniform constitutes an authority cue that adversely affects a child's ability to make accurate eyewitness identifications. Sixty participants aged 9–10 years old witnessed a staged crime and were later asked to identify a ‘burglar’ from a simultaneous line‐up using a 2 (uniform: present vs. absent) × 2 (target: present vs. absent) design. Children in the uniform present conditions made significantly more choices than children in the uniform absent conditions. More importantly, in the presence of a uniform, children made significantly more false identifications in target‐absent line‐ups. Analysis of supplementary, identification‐related variables (identification time and confidence, state anxiety) suggested that (1) the children experienced uncertainty if the target was absent from the line‐up, but (2) this uncertainty was not expressed when the line‐up administrator wore a uniform, leading to an increase in false identifications. Implications for line‐up administration procedures for children are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

解释学的后现代转向及其对后现代心理学的意义

随着后现代思潮的兴起,解释学领域出现了后现代转向,在对解释本身及解释模式的阐释、对成见的看法以及真理观等方面有许多转变,这些转变对后现代心理学产生很大影响,表现在:对研究对象的分析水平由个体中心转向对关系的研究;研究方法上由唯一客观的实证方法转向多元方法论;研究原则上由价值中立转向强调历史文化因素的影响;知识观上由追求知识的客观性、普适性转向知识的社会建构性。同时,后现代解释学对心理现象和实践应用的认识,对克服后现代心理学认识论和方法论上的相对主义也很有启发。     

Hyperplane arrangements in preference modeling

A standard representation of a family B of partial orders on a given finite set X is as a set of vertices of a cube. The metric and order structures on B inherited from the cube are often used in applications. In this paper, following Stanley [(1996). Hyperplane arrangements, interval orders, and trees. Proceedings of the National Academy of Sciences of the United States of America, 93, 2620-2625], we represent relations in B by regions and cells of a hyperplane arrangement arising from numerical representations of the partial orders in B. To illustrate this approach, we establish wellgradedness of some families of generalized semiorders. Although the families of linear and weak orders are not well graded, our approach allows the recasting of such concepts as well graded families of sets.
