Essentializing race: implications for bicultural individuals' cognition and physiological reactivity

It is a widely held belief that racial groups have underlying essences. We hypothesized that bicultural individuals who hold this essentialist belief about race are oriented to perceive rigid interracial boundaries and experience difficulty passing between their ethnic culture and the host culture. As predicted, we found that the more strongly Chinese American participants endorsed an essentialist belief about race, the less effective they were in switching rapidly between Chinese and American cultural frames in a reaction time task (Study 1), and the greater emotional reactivity they exhibited (reflected in heightened skin conductance) while they talked about their Chinese and American cultural experiences (Study 2). Taken together, these findings suggest that essentialist beliefs about race set up a mind-set that influences how bicultural individuals navigate between their ethnic and host cultures.     

MCM蛋白与肿瘤

微小染色体维持蛋白(MCM)是真核生物DNA复制的主要调控因子,在DNA复制的起始和延伸过程中有重要作用,在每个细胞周期中仅发生一次,是标志细胞增殖活性的新指标,对于肿瘤的诊断及预后判断有重要意义。     

轴突变性研究进展及思考

轴突变性是中枢神经系统疾病的基本病理过程,但是由于把其作为轴突失去胞体营养后的被动死亡,长期未受到重视。最近的研究发现轴突变性是神经元对外界刺激的可逆可控的主动过程,在这个研究过程中,我们体会到轴突变性所蕴涵的深刻哲学内涵,如其在细胞周期调控和凋亡的作用。这种研究使我们认识到应该用辩证的思维方法去认识分析客观事物。     

When is educational specialization heterogeneity related to creativity in research and development teams? Transformational leadership as a moderator

The authors examined conditions under which teams' educational specialization heterogeneity was positively related to team creativity. Using a sample of 75 research and development teams, the authors theorized and found that transformational leadership and educational specialization heterogeneity interacted to affect team creativity in such a way that when transformational leadership was high, teams with greater educational specialization heterogeneity exhibited greater team creativity. In addition, teams' creative efficacy mediated this moderated relationship among educational specialization heterogeneity, transformational leadership, and team creativity. The authors discuss the implications of these results for research and practice.     

冠心病患者药物支架的合理应用

药物支架的出现使冠脉成形术产生了质的飞跃,合理地应用药物支架将对患者带来福音.但是药物支架同样有中、晚期血栓形成,再狭窄等弊病.介入医生应从药物支架的适应证、禁忌证,支架操作的技术层面及中国国情,价/效比几个方面详细考虑应用药物支架的得失,遵循指南的建议,使患者获益并保证手术安全是最基本的要求.     

未成年患者的同意能力研究

众所周知,医疗机构必须在取得成年患者的有效同意后才能实施医疗行为.而当患者是未成年人时,这种对医疗行为的同意是否有效呢?对此,国内外法学均未形成统一的定论.通过比较国外医事法学领域相对成熟的同意能力理论,初步建立我国未成年患者的同意能力理论体系,其中评估方法是关键.     

复杂系统控制内隐学习范式的特点研究

在人工语法学习、序列学习以及复杂系统控制这三大内隐学习研究范式中,复杂系统控制范式尝试模拟出入们在实际问题解决过程中可能出现的内隐学习,具有更高的生态效度。对城市交通系统、英国经济学模型、糖生产任务以及人际交互任务等复杂系统控制任务进行研究后,我们得出复杂系统控制范式的特点：任务情境的自然性、学习过程的互动性、系统变化的连续性、系统规则的隐蔽性及内隐-外显学习的混合性等。     

文字与图片呈现形成想象空间记忆的比较

学习通过文字或图片方式显示的空间布局材料之后,采用空间定位任务．分别检验在不同朝向和相对位置的条件下,对想象空间方位判断的差异。结果表明,使用图片进行空间布局的学习,记忆后再各自以同样显示形式进行空间定位任务时,判断的速度比使用文字的反应时要快;同时,无论是文字还是图片形式呈现．在进行想象转向时．都会呈现朝向效应和相对位置效应。     

狭义情绪的神经—心理机制

在新近人们对情绪神经机制的探索中,很多研究成果都在表明,在通常概念下的人的情绪感受中,不仅有那种含有喜厌态度的更严格意义上的情绪成分,还有直接来自各种内外感官上的认知性感知觉成分。本文的目的是运用新近的情绪心理学研究成果,仅以情绪内在体验中的含有喜厌态度的心理成分作为情绪的心理实体,对其的神经—心理机制进行一些尝试性的解释,以期使通常概念情绪感受中的情绪成分和感觉成分更具可辨性。     

The lasting impression of chairman Mao: hyperfidelity of familiar-face memory

We examined the accuracy of a highly-familiar-face representation in memory. In experiment 1, a famous portrait of Chairman Mao was digitally altered in terms of the distance between his two eyes, two pixels at a time. Mainland Chinese adults were shown the original or altered photos, one at a time, and asked to determine whether each was that of Chairman Mao or altered. Eastern Asian and Caucasian participants, who were unfamiliar with Mao's photo, were shown simultaneously the original face paired with the altered ones and asked to determine whether the photos were identical. The Mainland Chinese participants' memory threshold approximated the perceptual discrimination threshold of the Eastern Asian and Caucasian participants. Experiments 2 and 3 ruled out that the result of experiment I was due to artifacts of photographic alteration. The findings of the present study suggest that our memory of a very familiar face is highly accurate, at least in terms of the interocular configuration. The accuracy is perhaps only limited by the perceptual resolution capacity of our visual system.
