Oscillatory priming and form complexity

Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display locations subsequently occupied by the target. Five experiments were performed to investigate how priming is affected by both the complexity and the geometry of prime/target forms. Experiment 1 showed that the subjective complexity of different polygons was coded in accord with an objective measure of form complexity. Experiments 2 and 3 revealed oscillatory priming to increase as a function of the subjective complexity of prime/target forms when those forms were regular and predictable. However, Experiments 4 and 5 showed that this relation did not hold when the prime/target forms were irregular and unpredictable. Taken together, it is argued that both subjective complexity and the Pr?gnanz quality of the prime/target forms come to determine the magnitude of priming. These results are discussed with reference to current physiological hypotheses regarding perceptual organization.     

Reliability and validity of Job Content Questionnaire in Chinese petrochemical employees

To evaluate psychometric properties the Chinese (mainland) version of the 30-item Job Content Questionnaire was administered to 889 employees in 4 industries of PetroChina. A retest at 3 months with 296 randomly chosen employees showed reliabilities ranged from .76 to .93. Cronbach coefficients alpha for the 8 dimensions ranged from .43 to .88, indicating that the Job Insecurity subscale had low internal consistency. Exploratory factor analysis showed 8 meaningful factors corresponding to the 8 theoretical dimensions of this questionnaire. This version has variable a but suitable retest to be a reliable and valid measure of job strain, applicable to the Chinese industrial working population of PetroChina.     

活性蛋白C：想说爱你不容易

重组人类活性蛋白C（rhAPC）为治疗重症脓毒症的药物,目前有证据表明rhAPC的市场策略有可能已经影响到专业机构诊治指南的制定与执行;rhAPC的临床疗效亦未能被大型临床试验继续证实,因此目前rhAPC的临床应用以及疗效评价要慎重进行。同时,有必要深入反思药品生产商与专业组织的利益关系,并制订对策以加强监管。     

慢性前列腺炎的诊治思考

慢性前列腺炎是男科的中青年十分常见的疾病,其病因和发病机制尚未完全明了,严重影响患者的身心健康;随着慢性前列腺炎的诊治规范相继出台,有利于规范慢性前列腺炎的诊治;中医药对慢性前列腺炎的治疗有一定的优势,但仍存在许多问题,应进一步建立中医药对慢性前列腺炎的诊治规范,本文探讨中外对前列腺炎的诊治方案,特别强调中西医结合治疗慢性前列腺炎的良好疗效。     

抑郁症的隐喻

抑郁症作为一类精神疾患其隐喻由来已久,精神病学与心理学对该病认识的不断深入,相互运作并将抑郁症置于异化之中,社会文化等诸因素强化了病患扭曲的认同感.从社会、文化功能的角度探讨隐喻对抑郁症病患心理的消极影响,旨在丰富我国抑郁症研究的医学社会学内容.

Contextualized personality: traditional and new assessment procedures

We describe our ongoing program of research related to the assessment of contextualized personality, focusing on social roles and cultural cues as contextual factors. First, we present our research employing the traditional assessment approach, wherein participants are asked to rate explicitly their personality across several different roles. We argue that this hypothetical approach is potentially susceptible to the influence of stereotypes, social desirability, and demand characteristics. We therefore describe the development of three novel and subtle assessment procedures that are based on obtaining online self-representations that are activated while occupying a specific context. Finally, the strengths and limitations of all four approaches, as well as directions for future research in the study of contextualized personality, are discussed.     

加工水平和呈现时间对错误记忆的影响

在DRM范式下,通过操纵加工水平和呈现时间,考察它们对错误记忆和真实记忆的影响.结果发现,加工水平对错误记忆没有影响,随着对词表加工水平的提高,错误再认率差异不显著.而加工水平对正确记忆有显著影响,不同加工水平间的正确再认率差异极其显著.错误记忆与正确记忆在加工水平上表现出了分离.在较慢呈现时间下,呈现时间对错误记忆和正确记忆的影响均不显著.     

"锚定参照错误"偏向对贝叶斯推理成绩的影响

采用贝叶斯推理问题作为实验材料,通过分析被试推理过程中的理由叙述,探讨被试贝叶斯推理所使用的启发式策略,从认知偏向的角度分析该问题的困难原因.结果发现:(1)在贝叶斯推理过程中,对"击中率"命题的"换位表征"错误和锚定"基础比率"信息导致了"锚定参照错误"偏向,从而表现出对贝叶斯推理成绩显著的高估或低估;(2)"锚定参照错误"偏向程度和锚定参照目标受任务情境的影响;(3)解决良构的问题和非良构的问题时,"换位表征"的现象都有可能发生,而且表现得比较一致.     

数学文化与儿童数学认知

数学文化以文化为视角.在人类文化发展的历史过程中审视和理解数学,为我们认识和理解儿童数学认知开辟了全新的方向.作为数学文化的重要内容的数学信念、数学价值观、数学典故、数学符号、数学法则以及实物工具等,在儿童数学认知的知识提取、理解与表征、记忆与策略、认知风格、情绪态度以及自我效能等方面起着重要的影响作用.
