The characteristics of social categorization based on the unidimensional variation of gender versus age

The present study explored the characteristics of social categorization based on the unidimensional variation of gender or age using the Garner’s Selective Attention Paradigm. The task of the experiment was to judge whether there was a mole on a person’s face, and the results showed that young participants’ response times were slower when the age or gender of the face stimuli varied, demonstrating that young people, rather than older people, can activate both an age category and a gender category automatically. Meanwhile, all participants’ responses to the old faces were slower than that to the young faces. Females reacted faster than males, demonstrating that females tend to have an advantage for face processing.     

情绪效价和唤醒对熟悉性和回想的不同影响

本研究检验了情绪的效价和唤醒对记忆提取阶段熟悉性过程和回想过程的影响及其心理机制。结果发现,编码阶段无分心任务时,积极图片的高、低自信再认准确率均高于消极图片,而唤醒对于高自信再认准确率的影响只限于消极图片;在编码阶段设置分心任务时,发现积极和消极的高唤醒图片的高自信再认准确率显著高于低唤醒图片。这些结果说明情绪的效价影响了熟悉性和回想两类记忆过程,而唤醒只影响回想过程,效价效应是编码阶段被试调用认知资源对积极图片进行精细加工的结果,而唤醒对回想过程的影响是自动编码高唤醒刺激细节的结果。     

影响图式归纳和类比迁移的三因素实验研究

该研究探讨被试的认知风格、源问题结构的清晰度及两个源问题间内容的相似性三者对图式归纳和类比迁移的影响。实验采用2×2×2的三因素完全随机设计。结果显示:(1)源问题图式表征的质量受到被试认知风格和源问题结构的清晰度两个变量的影响;(2)类比迁移的成绩只受到源问题结构清晰度的影响;(3)结构清晰的条件下,两类被试图式表征的质量无明显差异;结构不清晰的条件下,两类被试图式表征的质量出现明显差异。     

大脑半球互动对创造性科学问题提出能力的影响

以124名本科生为被试,通过划分利手程度(实验一)与添加眼动刺激(实验二)的方法,系统考察了大脑半球互动对创造性科学问题提出能力的影响作用。结果发现:(1)与强右利手被试相比,混合利手被试在创造性科学问题提出能力测验上的得分更高;(2)与非眼动组被试相比,眼动组被试在创造性科学问题提出能力测验上的表现更好;(3)大脑半球互动与问题情境在灵活性品质上存在交互作用,大脑半球互动对开放性问题灵活性品质的影响大于封闭性问题。     

Combined effect of early life stress and acute stress on colonic sensory and motor responses through serotonin pathways: differences between proximal and distal colon in rats

Clinically, adults who have experienced stresses in childhood present with episodes of serious symptoms of irritable bowel syndrome that are associated with acute stress, but the mechanism is not well understood. This study aimed to investigate the colonic sensory/motor responses to acute water avoidance stress (WAS) in male adult rats subjected to neonatal maternal separation (NMS), and the underlying mechanism of sensory/motor responses. Effects of the combined acute and early life stress on visceral sensation, colonic motility, and the tissue and luminal content of serotonin (5-hydroxytryptamine, 5-HT) in the proximal and distal colon were evaluated using the abdominal withdrawal reflex test, faecal pellet output measurement and capillary electrophoresis analysis, respectively. Results showed that WAS significantly increased not only visceral sensitivity but also colonic motility in NMS rats compared to the normal rats. These alterations were accompanied by significant increase in 5-HT content in the proximal but not the distal colonic tissues; these alterations were also associated with increased density of enterochromaffin (EC) cells in the proximal segment. In contrast, the faecal content of 5-HT increased similarly in both segments. Consecutive administration of parachlorophenylalanine to NMS rats was more potent at 500 mg kg?1 day?1 than at 150 mg kg?1 day?1 in suppressing colonic sensory/motor responses to WAS, corresponding to the greater reduction of the tissue and faecal content of 5-HT and of EC cell density in the colon. These data indicate that combined early life stress and acute stress effectively induce visceral hyperalgesia and motility disorder through 5-HT pathways in the colon of rats, and the proximal and distal colon have different responses towards the combined stressors.     

高校心理咨询师的专业能力及专业发展

本研究旨在了解高校心理咨询师的专业能力及专业发展。选取24名来自北京8所高校从事心理咨询的专职或兼职心理咨询师进行4个焦点小组访谈。研究发现,高校心理咨询接触到的主要问题是心理障碍,多数心理咨询师胜任工作的专业能力不足,专业训练和实践均有欠缺,专业发展的需求强烈。健全高校临床与咨询心理学学历教育,推行心理咨询师资格认证和审核制度以及完善继续教育机制是促进高校心理咨询师专业能力及专业发展的重要途径。     

儿童特质推理与情绪和效价线索理解的关系

本研究从情绪、效价两个角度探讨儿童特质理解与线索理解的关系。372名4、5、7岁儿童完成了贴标签和行为预测两类特质推理任务。实验一显示,所有年龄段儿童都能完成对情绪性特质害羞和胆小的推理,且特质和行为评定与情绪评定呈显著正相关;实验二显示,所有年龄段均能完成双重性质特质助人为乐和自私的推理,特质和行为评定与效价、情绪评定均呈显著正相关,回归分析则只有效价评定进入方程。结果说明,儿童完成情绪性特质推理任务时与情绪理解能力关系密切,而对双重性质特质推理时更多的与效价理解能力有关。     

学校组织气氛与教师工作绩效的关系分析

本研究借助于自编的学校组织气氛量表和教师工作绩效量表,通过对分层随机抽取的378名教师进行了调查,探讨了学校组织气氛与教师工作绩效的关系,结果发现学校组织气氛与教师工作绩效相关非常显著。回归分析和差异检验的结果进一步揭示:学校组织气氛是教师工作绩效的较好预测变量。其中,教学气氛是教师工作绩效的显著预测变量。同时,本研究还发现学校组织气氛对教师任务绩效影响非常显著,但对教师情境绩效影响不显著。     

The Antecedent Impact of Culture and Economic Growth on Nations` Creativity and Innovation Capability

Even though the literature has widely examined culture’s effect on nations’ creativity and innovation level, it has done little to address the system theory’s perspective. However, as proponents of the system theory have argued, nations’ creativity and innovation is the cumulative effort of the various stakeholders who operate as a system, so any assessment of a nation’s creativity and innovation must consider these stakeholders’ role. This study examines the overlooked effect of culture on the broader system aspect of eighty nations’ creativity and innovationto ensure representation by both developed and developing countries. Structural equation modeling using partial least squares software is applied to analyze the data. The study found out that nations with individualist and low power distance cultural values have the highest creativity and innovation, and that a nation’s economic growth level moderates the impact of the individualist cultural value. Policymakers who seek to develop a strategy that promotes creativity and innovation at the national level benefit from these findings. Future research directions are suggested.
