人际合作与冲突影响博弈决策的结果评价

人际合作与冲突是人际互动的两种主要形式, 在人类社会的发展中有着重要作用。脑成像研究表明, 当个体和人类同伴进行博弈时, 选择合作与选择冲突激活脑区的强度有所不同。但目前尚不清楚, 人际合作与冲突如何影响决策选择之后的结果评价过程。本研究采用Chicken Game任务对此问题进行了探讨, 研究记录了22名健康成人被试与人类同伴进行Chicken Game任务时的脑电活动。结果表明, 反馈负波(FRN)和P300不仅受到结果效价的影响, 同时也受到人际合作与冲突的影响。相对于选择冲突, 个体选择合作时, 输钱和赢钱反馈引发的FRN以及P300波幅差异更大。相关分析表明, RA (被试和解对方进攻)反馈引发的FRN波幅与接受该反馈后下一个trials中和解的选择率(以及总的和解率)呈显著的负相关。上述结果表明, 在社会博弈中, 合作增加了个体对博弈结果的预期, 从而引发更大的FRN效应; 并且合作共赢的结果所具有的物质意义与社会意义, 使其诱发更大的P300波幅。     

Narcissistic personality and risk perception among Chinese aviators: The mediating role of promotion focus

Optimism bias is a crucial feature of risk perception that leads to increased risk‐taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high‐stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory‐13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators.     

Be loyal but not addicted: Effect of online game social migration on game loyalty and addiction

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

Encoding lexical tones in jTRACE: a simulation of monosyllabic spoken word recognition in Mandarin Chinese

Despite its prevalence as one of the most highly influential models of spoken word recognition, the TRACE model has yet to be extended to consider tonal languages such as Mandarin Chinese. A key reason for this is that the model in its current state does not encode lexical tone. In this report, we present a modified version of the jTRACE model in which we borrowed on its existing architecture to code for Mandarin phonemes and tones. Units are coded in a way that is meant to capture the similarity in timing of access to vowel and tone information that has been observed in previous studies of Mandarin spoken word recognition. We validated the model by first simulating a recent experiment that had used the visual world paradigm to investigate how native Mandarin speakers process monosyllabic Mandarin words (Malins & Joanisse, 2010). We then subsequently simulated two psycholinguistic phenomena: (1) differences in the timing of resolution of tonal contrast pairs, and (2) the interaction between syllable frequency and tonal probability. In all cases, the model gave rise to results comparable to those of published data with human subjects, suggesting that it is a viable working model of spoken word recognition in Mandarin. It is our hope that this tool will be of use to practitioners studying the psycholinguistics of Mandarin Chinese and will help inspire similar models for other tonal languages, such as Cantonese and Thai.     

Organizational citizenship behavior and social loafing: the role of personality, motives, and contextual factors

The present study integrates the literature on social loafing and organizational citizenship behavior (OCB). The authors examined the roles of personality, motives, and contextual factors in influencing the work behaviors of OCB and social loafing. In a sample of 341 individuals working in project groups, with data collected over 3 time periods, the authors found that conscientiousness was negatively related to social loafing. They also found the known positive relation of OCB with conscientiousness. Felt responsibility was negatively related to social loafing. The authors found no significant relations between social loafing and OCB motives.     

Violent and disruptive behavior among drug-involved prisoners: relationship with psychiatric symptoms

This study examines the relationship between psychiatric symptoms and violent/disruptive behavior among 192 inmates who participated in prison-based substance abuse treatment. Participants came from two sites able to provide narrative reports of disciplinary actions in the Criminal Justice Drug Abuse Treatment Studies' Co-Occurring Disorders Screening Instrument study. In multivariate logistic models, a lifetime history of thought insertion/control ideation (OR, 11.6; 95% CI, 1.8-75.2), antisocial personality disorder (OR, 3.3; 95% CI, 1.2-8.9), and disciplinary action related to possession of controlled substances or contraband (OR, 4.9; 95% CI, 1.9-12.3) were associated with increased risk for violent or disruptive behavior while in prison, whereas lifetime phobic symptoms (OR, 0.2; 95% CI, 0.1-0.54) and high school graduation (OR, 0.4; 95% CI, 0.2-1.0) were associated with a decreased risk of violence and disruptive behavior in general. We conclude that, among inmates in substance abuse treatment, symptoms that increase risk for violence or disruptive behavior include thought control/insertion ideation and disciplinary infractions related to controlled substances, contraband, or failure to participate in assigned programs, as well a history of antisocial personality disorder.     

《人体器官移植条例》颁布后面临的问题与对策

《人体器官移植条例》规范引导着我国器官移植健康发展,然而,随着《条例》对器官移植供、受者条件的严格限制,尸体供器官数量迅速下降,亲属活体移植逐步占据主导地位,由此引发一系列问题。结合《条例》,就器官来源短缺、保障活体供者安全、亲属活体供者选择和器官移植伦理委员会作用等问题做出较详细的分析,提出解决方法和对策。

本文从应激的生化机制这一角度出发 ,融合吸收了近期内最具权威性的资料论述了A型行为与心身疾病的关系。认为A型行为者易发生应激 ,应激引起情绪的较大波动 ,强烈的情绪波动激活垂体———肾上腺皮质轴 ,同时交感———肾上腺髓质轴持续兴奋 ,两种作用会在体内引起不适当的激素环境而抑制免疫系统功能 ,降低人体防御效能。神经生理、神经内分泌和免疫三种机能相互联系在行为特点导致心身疾病的过程中起着中介作用     

具身心理治疗:原理与技术

具身心理治疗是以身体心理治疗、舞动治疗为代表的,理论上契合具身认知观点、实践中注重身体作用的一种当代心理治疗取向。它将“身体”与“躯体”区分开来,赋予身体解剖学的、感觉运动的、认知的与嵌入环境等不同层面的意义。当前,已有不少研究证实身体有助于改善治疗关系,促进来访者认知、情绪的改变,并发展出一系列注重身体内外感知、姿势或运动的非言语治疗技术。具身心理治疗重构了身体在治疗过程中的概念与角色,发展了新的技术,是传统心理治疗的有益补充; 但也存在实证证据不足、理论框架尚未完全整合、容易过分强调身体作用等问题。今后需自觉整合其他治疗流派、开发独特的核心技术,推进循证的具身心理治疗的发展。
