自我损耗促进冲动决策：来自行为和ERPs的证据

该研究以自我控制资源模型为理论框架, 采用行为实验和ERPs技术考察自我损耗对冲动决策的影响。实验1采用Stroop任务操纵自我控制资源并采用延迟折扣任务考察被试的决策冲动性, 实验2采用同样的实验任务并同时采用ERPs技术记录高、低自我损耗者在随后决策任务中的脑电成分。行为结果发现, 在控制心境、特质自我控制水平以及风险偏好等无关变量后, 高损耗者比低损耗者在延迟折扣任务上的折扣程度更大。ERPs结果发现, 不论延迟金额大小, 高损耗者在左侧额区诱发的N1波幅显著小于低损耗者; 高损耗者在右半球诱发的P2波幅显著大于低损耗者。研究表明, 自我损耗抑制决策早期左侧额区的激活水平, 个体因而无法识别冲突以及抵制即时满足的诱惑, 这促使他们采用直觉启发式进行决策, 最终导致冲动决策的产生。     

概化理论缺失数据方差分量估计

各种心理调查、心理实验中, 数据的缺失随处可见。由于数据缺失, 给概化理论分析非平衡数据的方差分量带来一系列问题。基于概化理论框架下, 运用Matlab 7.0软件, 自编程序模拟产生随机双面交叉设计p×i×r缺失数据, 比较和探讨公式法、REML法、拆分法和MCMC法在估计各个方差分量上的性能优劣。结果表明：(1) MCMC方法估计随机双面交叉设计p×i×r缺失数据方差分量, 较其它3种方法表现出更强的优势; (2) 题目和评分者是缺失数据方差分量估计重要的影响因素。     

非熟练双语者言语产生中非目标语言的激活范围

采用图-图干扰范式来考察非熟练中-英双语者言语产生中非目标语言的激活范围。实验1探讨用汉语命名时,干扰图的英语名称能否得以激活。结果发现,干扰图的词汇熟悉度高时,音译词的反应时显著长于音韵无关词,而熟悉度低时,二者无显著差异,说明在一语的产生过程中只能激活二语中高熟悉的非目标词。实验2探讨用英语命名时,干扰图的汉语名称能否激活。结果发现,不论熟悉度高还是低,音译词的反应时均显著长于音韵无关词,说明在二语的产生过程中会激活一语中的非目标词。总的结果说明,非熟练中-英双语者在言语产生过程中非目标语言中的非目标词也会激活,并且激活范围既受非目标语言的熟练程度的影响,也受非目标词熟悉度的影响。     

大学生外语写作自我效能感在写作焦虑对写作成绩影响中的中介效应

在外语写作课堂教学的情境下,使用写作自我效能感量表、外语写作焦虑量表和一篇英语命题作文分别调查356名大学一年级学生的外语写作自我效能感、写作焦虑与外语写作成绩,探讨写作自我效能感在写作焦虑与写作成绩之间的中介效应。结果表明:(1)外语写作焦虑显著负向预测外语写作自我效能感;(2)外语写作自我效能感显著正向预测外语写作成绩;(3)外语写作自我效能感在外语写作焦虑对外语写作成绩的影响中起到了完全中介的作用。     

Active inhibition of a distractor word: the distractor precue benefit in the Stroop color-naming task

The current study investigated attentional control through active inhibition of the identity of the distractor. Adapting a Stroop paradigm, the distractor word was presented in advance and made to disappear, followed by the presentation of a Stroop stimulus. Participants were instructed to inhibit the distractor in order to reduce its interference. Experiments 1 and 2 demonstrated that the distractor precue facilitated Stroop color naming by reducing Stroop interference. Experiment 3 demonstrated beneficial effects of the distractor precue when congruent trials were introduced. Experiment 4 showed that the distractor precue benefit was observed when the cue and target were in different forms. Experiment 5 indicated that if the item used as the cue became the target, naming it took longer in order to overcome the inhibitory effect. Experiment 6 demonstrated that the benefit of the distractor precue was not observed when the cue was uninformative. Finally, Experiment 7 demonstrated that active inhibition required working-memory resources to operate. This study suggests that the best explanation for the distractor precue benefit is the active inhibition account.     

学校氛围与初中生学业成就:学业情绪的中介和未来取向的调节作用

采用问卷法对1243名初中生进行调查研究,考察了学业情绪在学校氛围与初中生学业成就间的中介效应,以及未来取向对这一中介过程的调节效应。结果发现,（1）在控制了性别、年级、社会经济地位后,学校氛围对学业成就具有正向预测作用;（2）积极低唤醒学业情绪和消极低唤醒学业情绪显著中介学校氛围与学业成就的关系;（3）未来取向显著调节学校氛围对初中生学业成绩的直接路径,以及通过积极低唤醒和消极低唤醒学业情绪影响学业成绩的间接路径;即学校氛围和积极低唤醒学业情绪对学业成绩的影响在低未来取向的青少年群体中更为强烈;而学校氛围对消极低唤醒学业情绪的影响在高未来取向的青少年群体中更为强烈。总之,在学校氛围影响初中生学业成就的过程中,既存在中介效应,又存在调节效应。实际干预时,可以通过改善初中生学业情绪提高初中生的学业成就,未来取向可以进一步调节该过程。     

比例推理的过度使用及其认知机制:一项发展性的负启动研究

从抑制控制模型出发,采用负启动范式探究过度使用比例推理的认知机制。研究包括3个实验,以小学生、中学生和大学生为被试,分别考察了抑制控制在解决缺值应用题、图片推理任务中的作用,以及数字比(整数比、非整数比)是否对抑制控制过程有影响。结果发现:小学生、中学生和大学生在两类实验任务中均出现了负启动效应,但负启动量不存在年级差异;在图片推理任务中,不同数字比类型下的负启动量具有显著差异。研究结果支持了抑制控制模型的观点,即成功解决问题不仅需要掌握问题的内在逻辑,更需要对不恰当策略进行抑制;在解决问题的过程中,无论是儿童、青少年还是成人都需要抑制控制的参与,三者在抑制控制效率上没有差异;数字比类型对抑制过程有影响,但仅限于图片推理问题。     

心理治疗循证实践中“证据”的四个基本问题

循证实践正在成为西方心理治疗发展的主流方向。但如何理解循证实践的"证据"仍是见仁见智。部分社会大众甚至心理学专家仅将"循证"当作一种"修辞"或"时尚",顾名思义地界定"证据",或按主观信仰随意地选择与应用"证据"。文章以"证据"为研究焦点,试图建构系统理解"证据"的全面图景,探讨了心理治疗循证实践中关于"证据"的4个基本问题:(1)从历史考察与理论分析的视角出发,探讨了"心理治疗为什么需要证据";(2)从证据的类型范围、生产者及存在形式三个视角,描述了"心理治疗存在哪些证据";(3)从证据的科学程度、研究设计的严谨程度及解决实践问题的契合程度出发,阐述了"哪些证据才是好的证据";(4)从6个步骤推广证据及创新研究设计两个方面展开,分析了"在现实世界中如何推广与应用证据"。     

Differential emotion attribution to neutral faces of own and other races

Past research has demonstrated differential recognition of emotion on faces of different races. This paper reports the first study to explore differential emotion attribution to neutral faces of different races. Chinese and Caucasian adults viewed a series of Chinese and Caucasian neutral faces and judged their outward facial expression: neutral, positive, or negative. The results showed that both Chinese and Caucasian viewers perceived more Chinese faces than Caucasian faces as neutral. Nevertheless, Chinese viewers attributed positive emotion to Caucasian faces more than to Chinese faces, whereas Caucasian viewers attributed negative emotion to Caucasian faces more than to Chinese faces. Moreover, Chinese viewers attributed negative and neutral emotion to the faces of both races without significant difference in frequency, whereas Caucasian viewers mostly attributed neutral emotion to the faces. These differences between Chinese and Caucasian viewers may be due to differential visual experience, culture, racial stereotype, or expectation of the experiment. We also used eye tracking among the Chinese participants to explore the relationship between face-processing strategy and emotion attribution to neutral faces. The results showed that the interaction between emotion attribution and face race was significant on face-processing strategy, such as fixation proportion on eyes and saccade amplitude. Additionally, pupil size during processing Caucasian faces was larger than during processing Chinese faces.
