创伤后应激障碍的动物模型及其神经生物学机制

创伤后应激障碍是指个体由于经历对生命具有威胁的事件或严重的创伤,导致症状长期持续的精神障碍。研究创伤后应激障碍的主要动物模型为条件性恐惧和应激敏感化模型。研究表明,创伤后应激障碍中长时程留存的恐惧性记忆、高唤醒等症状与大脑杏仁核、内侧前额叶皮层和海马三个脑区及下丘脑-垂体-肾上腺轴负反馈功能增强密切相关。其中杏仁核活动增强是条件性恐惧记忆获得、保持和表达的关键神经基础。内侧前额叶皮层对杏仁核的去抑制及海马向杏仁核传递的威胁性环境信息,促进创伤后应激障碍症状的出现。在经历创伤应激后糖皮质激素受体的上调及多巴胺活动的增强是创伤后应激障碍产生的主要神经基础。对创伤后应激障碍的药物治疗研究证明多巴胺D2受体在改善患者症状中的作用比较重要,但仍需作更深入的探索     

中国文化背景下心理一致感的潜结构研究

采用实证研究方式对Antonovsky开发的13个项目的心理一致感量表在中国大陆的适用性进行探讨及修订。通过对1230名被试进行探索性及验证性因素分析后发现,个体的心理一致感是由可理解性、易处理性及意义性三个成分构成的总体,结果支持Antonovsky提出的关于心理一致感的构思,且经修订后的心理一致感量表对中国文化背景中的被试是适用的。     

Family interventions in psychosis: a scale to measure therapist adherence

The efficacy of family interventions in psychosis is well documented. UK and USA schizophrenia treatment guidelines advocate the practice of family interventions within routine clinical services. However, less attention has been paid to the study of treatment fidelity and the tools used in its assessment. This study reports the inter-rater reliability of a new scale: Family Intervention in Psychosis-Adherence Scale (FIPAS). This measure is designed to assess therapist adherence to the Kuipers et al . (2002) family intervention in psychosis treatment manual. Reliability ratings were based on a sample of thirteen audiotapes drawn from a randomized controlled trial of family intervention. The results indicated that the majority of items of the FIPAS had acceptable levels of inter-rater reliability. The findings are discussed in terms of their implications for the training and monitoring of the effectiveness of practitioners for family interventions in psychosis.     

Induction with uncertain categories: When do people consider the category alternatives?

These three experiments examined how people make property inferences about exemplars whose category membership is uncertain. Participants were shown two categories and a novel exemplar with a feature that indicated that the exemplar was more likely to belong to one category (target) than to the other (nontarget). Participants then made categorization decisions and property inferences about the novel exemplar. In some conditions, property inferences could be made only by considering both target and nontarget categories. In other conditions, predictions could be based on both categories or on the target category alone. Consistent with previous studies (e.g., Murphy & Ross, 1994, 2005), we found that many people made predictions based only on consideration of the target category. However, the prevalence of such single-category reasoning was greatly reduced by highlighting the costs of neglecting nontarget alternatives and by asking for inferences before categorization decisions. The results suggest that previous work may have exaggerated the prevalence of single-category reasoning and that people may be more flexible in their use of multiple categories in property inference than has been previously recognized.     

Discerning the Relations Between Conversation and Cognition

Although hailing from cognate analytical schools, the contributors to Hedwig te Molder and Jonathan Potter’s edited volume Conversation and Cognition hold a remarkable diversity of views on the nature of “mental states” and their import for the purposes of analyzing naturally occurring interaction. I offer a critical analysis of some of the contributors’ discussions of cognition in social interaction in an effort to clarify some obstinate issues with respect to the meanings of words in our cognitive vocabulary (e.g. “thought” and “realization”) and their identification in analyses of conversation.     

当代中国人价值观的结构与特点

本研究以事实驱动作为方法学切入点, 系统研究了中国人的价值观结构及特点等问题。研究采用通过系统编制形成的《中国人价值观问卷》, 对工人、农民、专业技术人员、大学生和中学生五类人群进行了测量。其中, 1100份有效数据的探索性因素分析表明, 中国人价值观是一个8因素结构, 具体包括品格自律、才能务实、公共利益、人伦情感、名望成就、家庭本位、守法从众、金钱权力; 随后对1196份有效数据进行结构验证和信度检验, 结果表明中国人价值观问卷(Chinese Values Questionnaire, CVQ)具有良好的构想效度和信度。同时, 通过对中国人价值观现状的分析发现, 中国人价值观具有“好人定位”特点, 并据此提出相应的理论模型。     

网络成瘾者不同情绪状态下的认知加工特征

取在校大学生454人,通过《青少年病理性互联网使用量表》（Adolescent Pathological Internet Use Scale, APIUS),筛查出网络成瘾者31名为实验组,随机抽取样本中其他非成瘾大学生31人为对照组。使用词首－词尾对应三重意义组合图片60个为实验材料,用人物图片为情绪启动刺激,研究被试在不同情绪状态下的认知选择,记录被试选择词组性质和反应时间。研究发现,所有被试对积极词语的选择最多,对消极词语的选择最少,表现出“趋乐避苦”的认知选择倾向;成瘾组被试对积极词语的选择比对照组少,但是对消极词语选择比对照组多。悲伤启动情况下,成瘾组被试对积极词语的选择比对照组少,但是对消极词语的选择则比对照组多。成瘾组被试对积极信息的选择速度比对照组慢,但是对中性信息和消极信息的选择速度则比对照组快。愉快情绪启动下,成瘾组被试的反应时间比对照组短,在悲伤情绪启动下,成瘾组被试的反应时间比对照组长。悲伤情绪启动下,成瘾组被试对积极词语的反应时间比对照组慢,但是对消极词语的反应时间比对照组快。这些研究结果对网络成瘾的治疗有重要的参考价值。     

Affective atmospheres

In this paper I reflect on the concept of affective atmospheres in the context of the distinction between affect and emotion that has emerged in recent work on emotion, space and society. The concept of atmosphere is interesting because it holds a series of opposites -- presence and absence, materiality and ideality, definite and indefinite, singularity and generality -- in a relation of tension. To develop this account of atmosphere I juxtapose Marx's materialist imagination with a phenomenology attentive to singular affective qualities. By invoking a material imagination based on the movement and lightness of air, we learn from the former about the turbulence of atmospheres and their indeterminate quality. From the latter, we learn that atmospheres are singular affective qualities that emanate from but exceed the assembling of bodies. As such, to attend to affective atmospheres is to learn to be affected by the ambiguities of affect/emotion, by that which is determinate and indeterminate, present and absent, singular and vague.     

The Price of Pain and the Value of Suffering

ABSTRACT— Estimating the financial value of pain informs issues as diverse as the market price of analgesics, the cost-effectiveness of clinical treatments, compensation for injury, and the response to public hazards. Such valuations are assumed to reflect a stable trade-off between relief of discomfort and money. Here, using an auction-based health-market experiment, we show that the price people pay for relief of pain is strongly determined by the local context of the market, that is, by recent intensities of pain or immediately disposable income (but not overall wealth). The absence of a stable valuation metric suggests that the dynamic behavior of health markets is not predictable from the static behavior of individuals. We conclude that the results follow the dynamics of habit-formation models of economic theory, and thus, this study provides the first scientific basis for this type of preference modeling.     

Framing and Editing Interpersonal Arguments

Since argument frames precede most other arguing processes, argument editing among them, one’s frames may well predict one’s preferred editorial standards. This experiment assesses people’s arguing frames, gives them arguments to edit, and tests whether the frames actually do predict editorial preferences. Modest relationships between argument frames and argument editing appear. Other connections among frames, editing, and additional individual differences variables are more substantial. Particularly notable are the informative influences of psychological reactance. A new theoretical contribution is offered, connecting argument frame research to Erving Goffman’s frame analysis.
