正负效价面部表情图片加工的差异

为探讨正负效价面部表情图片识别的差异,采用独立呈现范式呈现正负效价面部表情图片,控制呈现时间和提示线索位置,并利用眼动仪记录识别过程中的眼动指标。结果发现:(1)在识别速度和正确率上,加工积极面部表情图片高于加工消极面部表情图片,显示出积极表情优势。(2)呈现时间没有改变正负效价表情图片加工之间的差异。(3)存在提示线索位置效应,即提示线索在嘴部有利于面部表情识别。(4)面部表情识别遵循"眼部-嘴部-眼部"的规律。结果提示不同性质面部表情的加工机制不同,加工深度作用小于线索作用。     

Development of a Brief Motivational Enhancement Intervention for Intimate Partner Violence in Alcohol Treatment Settings

The current studies were a manual development study and a small pilot study of a 90-minute motivational enhancement style intervention to address intimate partner violence in alcohol-treatment-seeking men. Analyses of feedback provided during manual development suggest participants (a) liked the intervention, (b) reported behavior change intentions, and (c) found the feedback compelling. Findings from the pilot study suggest the intervention might be superior to referral only in increasing short-term help-seeking and lead to marginally significant enhancements in motivation and self-reported intimacy. Help-seeking and motivation findings were associated with medium-large to large effect sizes. At 3- and 6-month follow-up, both groups showed improvements in self-reported alcohol outcomes, anger, and verbal and physical aggression. These findings support further research on this intervention.     

Statement Validity Analysis

Summary

All information regarding 103 Dutch sexual abuse cases was analyzed using the Validity Checklist, the second part of the Statement Validity Analysis procedure. The fulfillment of the VC items was compared for four different age groups. Only two VC items differed significantly between the age groups. The systematic summarization of content analysis and validity checks revealed only a weak relationship between the fulfillment of the CBCA criteria and the VC items together and the outcome of the cases. The results suggest that SVA cannot yet be used as a scientifically validated instrument for judging the truthfulness of allegations of child sexual abuse.     

A Brief Motivational Intervention for Treatment‐Refusing OCD Patients

Cognitive behavioral therapy involving exposure and response prevention (ERP) is the psychosocial treatment of choice for obsessive‐compulsive disorder (OCD). Despite this, ERP is not widely used by mental health practitioners, and so dissemination of ERP and other empirically supported treatment (ESTs) has become a priority. Even so, utilization of ESTs such as ERP remains below 50% even among therapists who self‐identify as having a cognitive behavioral orientation. Barriers to the acceptance of ERP include practical obstacles such as lack of training and the cost of treatment, but also patient variables such as treatment refusal. It has been estimated that approximately 25% of OCD patients refuse ERP. This paper describes a brief, 4‐session readiness intervention (RI) designed to decrease ERP refusal among patients with OCD. In this study, 12 patients with OCD who had refused ERP were randomized to RI or wait‐list (WL). 86% of participants in the RI condition and 20% of participants in WL condition agreed to begin ERP following the 4‐week period. ERP following RI, but not WL, was associated with a decrease in OCD symptoms comparable to that observed in OCD patients who did not refuse ERP. However, ERP following RI was associated with a high drop‐out rate (50%), a figure that exceeds that typically seen in OCD treatment studies. Techniques to reduce drop‐out as well as directions for future research are discussed.     

跨期选择的性质探索

跨期选择指人们对发生在不同时间点的价值做出的权衡与决策。大量研究证明, 跨期选择中人们存在普遍的时间折扣倾向, 即将未来的价值折扣后与当前价值进行权衡。跨期选择研究不仅与人类心智的起源与机制等基础科学问题密切相关, 也关系到国家公共政策的制定等现实问题。本项目拟采用实验室研究和大规模问卷调查结合的方法, 深入探索跨期选择的本质。一方面, 采用实验室研究法探讨影响跨期选择的重要因素, 以探索：(1) 跨期选择的效价及其与价值数量、延迟时间的交互作用及其心理机制; (2) 跨期选择中是否存在领域特异性及其心理机制; 另一方面, 通过全国范围的调查, 从而：(1) 建立中国城镇居民时间折扣率的常模; (2) 测量不同类型人群的时间折扣率, 以探讨跨期选择的性质与内涵。项目研究结果将有利于加深学界对跨期选择现象的理解。     

特征框架效应的心理机制与影响因素

特征框架效应是指当分别以积极框架和消极框架来描述给定情境中某一事物或事件的关键特征时, 一般情况下人们更偏好以积极框架来描述其关键特征的事物或事件的现象。特征框架效应广泛的存在于消费、医学及政治等领域。目前, 它的解释机制主要包括效价加工的认知机制、参照依赖、查询理论以及认知神经机制。它的影响因素主要包括经验、人格特质、计算能力以及认知闭合需要等。未来的研究应该从深入探索特征框架效应的产生根源和影响因素, 拓展其应用研究, 深入探索偏好消极框架下的特征框架效应以及探讨该现象与其它现象之间的关系等五方面展开。     

老年人错误记忆的情绪效价和时间效应

基于信号检测论的框架, 考察不同的情绪效价以及时间间隔如何交互影响老年人在图片再认任务中的辨别力(d′)和判断标准(β), 进而影响其错误记忆。以21名老年人(女性14名)为被试, 平均年龄67.17 ± 5.03岁。根据中国老年人对国际情绪图片库(International Affective Picture System, IAPS)中图片评定的情绪参数, 选出积极、消极和中性图片各60张作为学习材料。另选积极、消极和中性图片各30张作为每次再认测验的干扰材料, 并且两次再认测验的干扰材料不同。短时间隔条件让老年人在图片记忆编码半个小时后完成对图片的再认测验; 长时间隔条件则为在三周后完成对图片的再认测验。结果发现: 1)在短时间隔条件下, β和d′共同影响虚报率; 而在长时间隔条件下, 只有β影响虚报率, d′不影响虚报率; 2)无论是在短时还是长时间隔条件下, 积极图片与消极图片的判别力d′都没有显著差别; 3)在短时间隔条件下, 老年人对消极图片的β更低、虚报率更高; 在长时间隔条件下, 老年人对积极图片的β更低、虚报率更高。研究结果表明: 老年人的错误记忆受判别力d′和判断标准β的影响。情绪效价通过作用于老年人的反应倾向(判断标准β)、而非记忆质量(判别力d′)来影响其错误记忆。时间间隔可以调节情绪效价对老年人判断标准β和错误记忆的作用, 使之随时间发生反转。老年人的“积极效应”在错误记忆中可能表现为随着时间的流逝, 老年人更愿意将积极信息报告为经历或学习过的信息。     

内隐自我正面偏见的机制及可变性

自我正面偏见是指对大多数个体来说, 其自我相关信息与正性情绪效价联系紧密, 个体倾向于把正面结果或特质归因于自我内部稳定的人格特征, 而认为负面结果或特质与自己的人格特征不相关。本项目从自我正面偏见的文化相对论与文化普遍论之争出发, 采用行为和认知神经科学技术, 试图证实集体主义文化下自我正面偏见的存在, 并对照外显自我正面偏见, 考察内隐层面上的自我正面偏见及其可变性, 探索抑郁个体的内隐自我相关信息加工的改善, 了解其大脑神经基础, 揭示内隐自我正面偏见的性质与特征, 验证和完善自我相关信息与情绪信息的功能加工层次模型。研究结果不仅有助于从内隐层面上了解自我与情绪的复杂关系, 而且还将对其神经基础做出重要探索, 更深入地解读中国人的自我的本质。     

愤怒的聚光灯效应对个体新闻阅读的归因影响

最初情绪的聚光灯理论仅从效价角度出发,解释了情绪通过影响注意范围,干涉个体归因,没有针对其它情绪（譬如愤怒）做进一步验证。本研究通过2（情绪）×2（因素显著性）×2（性别）的被试间实验设计,进一步揭示了愤怒的聚光灯效应对个体新闻类信息归因的影响方式。共有243名在校学生参加实验,其中男生99名,年龄在19~25岁之间。本研究将原有的锚式（anchor）归因计分改为对显著和非显著信息独立计分。结果发现：愤怒对个体归因的影响结果与负性情绪的聚光灯效应相一致,并且具有双向性。一方面增加了对显著因素的归因倾向,一方面抑制对非显著的归因素因倾向,且不存在性别差异。另外,本研究发现新闻中某一信息的显著程度亦会造成归因偏差。本研究为聚光灯理论提供了新的实验支持,并就愤怒效价上的模糊性做了进一步的解释和讨论。     

Effects of valence and framing in decision making II: Estimating subjective weighting1

Abstract: In comparison between choice options, judgments of “How much better is a preferred option?” and “How much worse is a less preferred option?” may differ in their magnitudes. Such discrepancies are called “valence effects.” Previously, Yamagishi and Miyamoto (1996) observed systematic positive valence effects (“Better” exceeding “Worse”) in the domain of gains and systematic negative valence effects (“Worse” exceeding “Better”) in the domain of losses. The current experiment used the directions of valence effects as a tool to assess the decision maker's interpretation of choice tasks under the “framing effect” ( Tversky & Kahneman, 1986 ). Preferences under the framing effect switch from certain options in the domain of gains to uncertain options in the domain of losses. This study examined whether preferences for certain options were associated with positive valence effects, whereas preferences for uncertain options were associated with negative valence effects. Moreover, conditions under which preference reversals under the framing manipulations ceased to occur were examined. The effects of valence showed that framing effects ceased to occur when decision makers maintained consistent task interpretations as pertaining to gains or to losses. Most importantly, the pattern of subjective weighting under the valence effects was consistent with previous explanation of valence effects ( Yamagishi & Miyamoto, 1996 ). Possibilities for extending the current findings to understanding related psychological phenomena are discussed.
