简单情绪感染及其研究困境

个体之间实现情绪聚合的过程称为情绪感染。其中通过自动同步模仿他人表情、言语、姿势和行为并实现情绪聚合的无意识倾向称为简单情绪感染。近年来简单情绪感染的发生机制得到了大量行为实验和脑科学研究的支持。然而由于其“无意识”、“同步”、“自动”发生的特点, 以及研究者长久的争论与界定不清, 使得该领域研究面临不少困境。为了厘清这些困境, 在梳理有关研究的基础上, 总结了简单情绪感染的社会影响因素, 分析了简单情绪感染在概念界定、测量方式、依赖线索等方面的问题, 并尝试给出可行性建议。今后研究应当采用更先进的技术手段及范式展开, 并结合新近研究成果对简单情绪感染的机制理论进行更新。     

汶川地震三年半后中学生的感恩对创伤后成长的影响：社会支持的中介作用

采用感恩问卷、社会支持问卷和创伤后成长问卷对汶川地震三年半后的376名中学生进行调查,考察其感恩与社会支持对创伤后成长的影响,并检验社会支持在感恩与创伤后成长之间的中介作用。结果发现：（1）灾后中学生的创伤后成长水平较高,其中自我觉知的改变与人际体验的改变水平高于生命价值观的改变水平,女生人际体验的改变水平高于男生,初一学生的创伤后成长水平相对低于高年级学生;（2）感恩和社会支持可显著地正向预测创伤后成长;（3）社会支持在感恩与创伤后成长之间起着部分中介作用。这表明,汶川地震三年半后中学生的感恩可以直接正向预测创伤后成长,也可通过社会支持正向影响创伤后成长。     

空气污染的不良效应及理论模型:环境心理学的视角

空气污染的不良效应不仅限于生理健康损害,还涉及认知功能、情绪和行为等多方面的消极影响。针对空气污染不良效应的形成机制,以往研究提出了环境应激模型和社会-环境交互模型,这些理论模型强调空气污染的不良效应不仅涉及污染的直接暴露程度,也取决于个体的身心状况以及他对空气污染的主观评价。基于以往研究的不足,尤其是环境心理学介入空气污染研究的可行性,未来研究可着眼于改进空气污染的心理学研究方法,开展空气污染的环境应激和风险感知研究。     

父母婚姻质量对青少年行为的影响:父母教养能力感的中介作用

以160个家庭中的父亲和母亲为被试,采用问卷法,由父亲和母亲分别报告自己感知的婚姻质量、教养能力感、青少年的亲社会和问题行为,以探讨父母婚姻质量对青少年亲社会、问题行为的影响,并检验教养能力满意度和效能感的中介作用。结果发现:(1)父亲和母亲报告的婚姻质量越好,青少年表现出的亲社会行为越多,问题行为越少;(2)父亲的教养能力满意度在父亲报告的婚姻质量与青少年问题行为的关系中具有部分中介作用;(3)母亲的教养能力效能感在母亲婚姻质量对青少年亲社会、问题行为的影响中起部分中介作用;另外,母亲的教养能力满意度在母亲婚姻质量和青少年问题行为之间的中介效应为边缘显著。     

The influence of visual mental imagery size on metamemory accuracy in judgment of learning

Many studies have found the font size of to-be-remembered words has a significant influence on judgments of learning (JOLs). However, few studies have investigated whether JOLs are affected by the mental imagery size of to-be-remembered words, even when the font sizes themselves are kept identical in study materials. This study investigated whether the visual mental imagery size influences the participants’ JOLs and what the underlying mechanisms are. In Experiments 1 and 2, participants learned words with identical font sizes, mentally generated large or small imageries and then made JOLs. We found that JOLs under the large imagery condition were significantly higher than those under the small imagery condition, but actual recall performance exhibited no significant difference. In Experiment 3, participants pressed a button immediately after mental imagery generation and showed that it took significantly longer to generate large imageries than to generate small imageries, and the difference in JOLs between two conditions was no longer significant. In Experiment 4, we used a questionnaire to investigate the contribution of beliefs and found that participants believed large imageries were easier to remember. These findings indicate that imagery size has a significant impact on JOLs, in which beliefs may play a leading role.     

社会支持对青少年创伤后成长的影响:状态希望和积极重评的中介作用

采用创伤暴露程度问卷、社会支持问卷、状态希望量表、认知情绪调节量表和创伤后成长问卷,以雅安地震2.5年后的397名中学生为被试,考察其社会支持、状态希望、积极重评与创伤后成长（PTG）之间的关系。结果发现,雅安地震2.5年后青少年的社会支持可以直接正向预测PTG,不过,在社会支持与PTG之间纳入状态希望和积极重评后,社会支持不能直接地促进PTG,但却可以分别通过状态希望和积极重评来促进PTG,还可以经过状态希望由积极重评的多重中介来正向预测PTG。     

美国华人移民的异文化压力:特点、影响因素和中介效应

从美国NLAAS的调查数据中直接抽取美国华人移民样本473份,探讨美国华人移民异文化压力的特点、影响因素及中介效应。结果显示:美国华人移民体验的异文化压力较大,且与多因素存在显著相关,英语熟练度、移民时的年龄、移居美国的年数和种族歧视对压力具有显著预测性;社会地位作为中介变量可以有效缓冲美国华人移民的异文化压力。     

Longitudinal Linkages Between Posttraumatic Stress Disorder Symptoms and Violent Behaviors Among Chinese Adolescents Following the Wenchuan Earthquake

This study was conducted to examine the longitudinal relations between posttraumatic stress disorder (PTSD) symptoms and violent behaviors. In this study, 415 adolescent survivors of the Wenchuan earthquake in China (May 12, 2008) were assessed by using self-report questionnaires 1 year (T1), 1.5 years (T2), and 2 years (T3) after the earthquake. The findings suggested that from 1 to 1.5 years after the earthquake, only intrusive symptoms of PTSD were a risk factor for violent behaviors, whereas violent behaviors were a risk factor for all 3 PTSD symptom clusters. Furthermore, 1.5 to 2 years after the earthquake, avoidance symptoms of PTSD were a risk factor for violent behaviors and hyperarousal symptoms of PTSD had no significant relation with violent behaviors.     

汉语句子加工中句法信息与语义信息的交互作用：来自ERP的证据

采用ERP技术考察句子加工过程中句法信息和语义信息交互作用的时间进程。以汉语“把字句”为实验材料,分别比较句法违例句与双重违例句的LAN和P600效应、语义违例句与双重违例句的N400效应。与句法违例句相比,双重违例句的LAN效应的波幅更负,潜伏期更长,皮层分布更广泛;双重违例句的P600效应出现减弱趋势;双重违例句的N400效应的潜伏期显著长于语义违例句。结果表明,在句子加工的各个阶段,句法信息和语义信息呈持续交互作用,支持句子的平行加工模型。     

Biases in orienting and maintenance of attention among weight dissatisfied women: an eye-movement study

Despite evidence indicating fatness and thinness information are processed differently among weight-preoccupied and eating disordered individuals, the exact nature of these attentional biases is not clear. In this research, eye movement (EM) tracking assessed biases in specific component processes of visual attention (i.e., orientation, detection, maintenance and disengagement of gaze) in relation to body-related stimuli among 20 weight dissatisfied (WD) and 20 weight satisfied young women. Eye movements were recorded while participants completed a dot-probe task that featured fatness-neutral and thinness-neutral word pairs. Compared to controls, WD women were more likely to direct their initial gaze toward fatness words, had a shorter mean latency of first fixation on both fatness and thinness words, had longer first fixation on fatness words but shorter first fixation on thinness words, and shorter total gaze duration on thinness words. Reaction time data showed a maintenance bias towards fatness words among the WD women. In sum, results indicated WD women show initial orienting, speeded detection and initial maintenance biases towards fat body words in addition to a speeded detection – avoidance pattern of biases in relation to thin body words. In sum, results highlight the importance of the utility of EM-tracking as a means of identifying subtle attentional biases among weight dissatisfied women drawn from a non-clinical setting and the need to assess attentional biases as a dynamic process.
