不确定性容忍度对风险偏好的影响及其情景依赖性

研究以经营店面为背景设计决策材料,采用2(不确定性容忍度:高/低)×2(损益背景:损失/获益)×2(选项描述框架:积极/消极)×3(损益概率:高/中/低)混合实验设计,探讨不同任务情景下个体不确定性容忍度对风险偏好的影响。结果发现,不确定性容忍度主效应显著,高容忍度者比低容忍度者更冒险。不确定性容忍度与损益背景交互作用显著：在损失背景下,高容忍度者比低容忍度者更冒险,在获益背景下无此效应。不确定性容忍度与选项描述框架交互作用显著：在积极框架下,高容忍度者比低容忍度者更冒险,在消极框架下无此效应。这表明,不确定性容忍度对风险偏好产生影响,但这种影响会受到损益背景和选项描述框架的调节,具有情景依赖性。     

公正世界信念的文化差异

公正世界信念的文化差异是该领域较少关注的研究方向, 但具有一定的理论意义和实践价值。公正世界信念的水平、功能和测量工具存在文化差异, 其影响因素主要包括社会文化因素、自我概念、认知方式和不公平的社会现实。文章进一步探讨了提高公正世界信念跨文化比较准确性的途径和文化影响公正世界信念的机制。未来的研究需要深入探讨文化对公正世界信念功能的影响, 推进公正世界信念的本土化研究。     

决策风格的理论发展及建构：基于信息加工视角

决策风格是人们在决策中表现出来的习惯性或独特的行为模式, 对决策、管理等领域均有重要影响。近年兴起的决策风格理论主要基于个体信息加工策略, 如基于双加工理论和基于后悔情绪的决策风格模型等。决策风格对个体决策的影响表现在决策策略与偏差、情绪和无意识加工等方面。该领域在诸如决策风格的主要理论、测量工具和理论检验等方面亦取得积极进展, 未来研究方向应注意基于双加工理论和进化心理学建构决策风格理论。     

Individual differences in distance travelled by serial burglars

This paper uses police data on a sample of 41 serial burglars committed in the city of St John's, Canada and surrounding areas, to examine individual differences in distances travelled. In accord with findings from studies in other locations, results show that serial burglary is a localised activity. Differences between serial burglars in distances they travel are related to the burglars' age, method of transportation and value of property stolen. These results are discussed in terms of existing explanations of distances that serial burglars travel to select targets and implications for police decision‐making.

小学儿童认知发展的个体差异研究

使用皮亚杰经典任务探查了小学一、三、五年级儿童的认知发展以及发展的个体间差异和个体内差异。结果表明随着年级的升高,儿童的具体运算思维能力从一年级到三年级发展迅速,到五年级时达到比较稳定的水平;同时,形式运算思维能力在一年级已经萌芽并逐步发展。不管在具体运算任务还是形式运算任务,各年级儿童都表现出显着的个体间差异和个体内差异。这些发现对教育和临床心理都有重要的意义。     

自传记忆线索提取发展的实验研究

自传记忆是关于个人生活的记忆。发展心理学家以生命历程的视野来研究自传记忆的发生、发展、变化是自传记忆研究的重要组成部分。自传记忆的形成和发展可分为三个阶段 :即童年期遗忘、回忆高峰、自传记忆近因期。本实验采用 2 (提取方式 :顺时、自由回忆 )× 2 (性别 :男、女 )× 8(年龄 :8个年龄组 )混合设计 ,结果发现 :(1 )顺时提取与自由提取两种提取方式对自传记忆的提取存在年龄差异 ,不仅有提取速度的差异 ,也存在提取内容的差异。 (2 ) 8个年龄段两种提取条件下的平均提取速度具有一致的趋同性 ,呈U型曲线 ,存在自传记忆的回忆高峰。 (3)自传记忆的跨生命历程提取不存在性别差异 ,年龄、性别、提取方式间不存在交互作用。 (4) 8个年龄段自传记忆的提取速度、提取内容与个人各年龄的生活主题存在内在关联。 (5)从提取机制支持Conway关于生命历程自传记忆发展的三阶段假设     

Different forms of aggression among inner-city African-American children: Gender, configurations, and school social networks

Using narrative reports of peer conflicts among a sample of African-American children and adolescents from inner-city schools, this study investigated the development and social functions of four types of aggressive behaviors: social, direct relational, physical, and verbal aggression. A total of 489 participants in grades 1, 4, and 7 were interviewed (220 boys and 269 girls). Results showed that low levels of social aggression and high levels of physical aggression were reported in peer conflicts. Gender differences on social, direct relational, and physical aggression were primarily observed in the comparisons of same-gender conflicts at grade 7. Distinct configurations were identified across different forms of aggression. Boys with configurations of physical and/or verbal aggression had higher levels of school social network centrality than non-aggressive boys. Girls with configurations of social and/or direct relational aggression showed relatively higher levels of network centrality than non-aggressive girls.     

Sport team identification and willingness to consider anonymous acts of hostile aggression

Previous research indicated that a sizeable minority of individuals report a willingness to consider engaging in anonymous acts of instrumental aggression directed toward players and coaches of a rival team. Individuals with a high degree of identification with their favorite team were particularly likely to consider such acts. The current investigation was designed to extend this research by examining the likelihood that individuals would consider engaging in hostile anonymous aggression. It was expected that highly identified persons would be particularly likely to consider these acts, even though the acts would not provide a competitive advantage for their team. Data collected from 175 university students confirmed the expectations. In addition, the results indicated that males were more likely than females to report a willingness to consider the hostile aggressive acts and that participants were more likely to report a willingness to engage in less destructive acts (e.g., tripping an opposing player or coach) than more destructive acts (e.g., murdering an opposing player or coach).
