非典病原发现的方法论反思

从非典病原体发现的科学突破中,我们可以得出四点科学方法论的启示:(1)观察应全面,实验要充分;(2)小心使用不完全归纳法;(3)做出结论应慎重,发表假说要及时;(4)合作与良性竞争是科研成功的一大法宝.对我国科学工作者在这场科研战中的贡献与失误进行了方法论方面的反思.     

个体主义/集体主义的影响因素:生态视角

个体主义/集体主义是衡量文化的重要维度。两者的价值取向有所区别,前者关注自我的独特性,而后者关注自我与他人的关系。近年来研究者发现了众多影响个体主义/集体主义的新因素并构建了理论。这些理论中有4个理论非常具有代表性:现代化理论、气候-经济理论、传染病理论以及大米理论。其中后3个理论从远因的角度来对个体主义/集体主义的成因进行了探讨,为研究者探究个体主义/集体主义成因提供了新思路。未来个体主义/集体主义影响因素的研究可以用多种测量方法综合的方式或者从基因的角度来进行探索。     

疾病的心理防御：人类如何应对病菌威胁

病菌和传染病构成的选择压力导致动物进化出了身体免疫以及行为免疫反应。而人类的大脑进化促使他们发展出了最为复杂的行为免疫系统。很早开始, 我们就依赖自身的各种行为免疫反应抵抗病菌。当这些疾病抵御机制跟群体生活协同进化之后, 我们的很多社会行为和态度都具有了减少疾病感染的功能, 它们包括对外群体成员的偏见、歧视, 以及对内群体成员的从众、服从。而更高层次的文化差异比如集体主义-个人主义, 至少部分原因是要管理与疾病感染有关的风险。本篇综述讨论了与抵御病菌威胁有关的社会行为、态度和其他心理现象。     

SARS:希望与挑战

经过全球各方面不懈努力,对SARS的研究、防控现巳取得阶段性进展：新型冠状病毒巳被确定为致病原,病毒基因组巳解析、诊断技术巳用于临床、疾病的流行规律正在描述、有效防控措施巳采用等,所有的一切有赖于全球的协作、科学的力量。但是,人类在彻底控制SARS之前还需要大量工作,目前还存在许多亟待解决的问题。     

Terraforming Mars and Marsforming Terra: Discovery Doctrine in Space

Harvard’s E.O. Wilson answered a millennia-old question by stating “ET is out there.” We are not alone in the cosmos. Humankind is devastating Earth ecologically, threatening her survival and that of all living beings—including themselves. Humans harm their own communities through economic, ethnic, and gender inequalities. Would humankind think and act similarly on other worlds? The Discovery Doctrine used by Europe to colonize indigenous lands seems resurrected. If humanity appears a pathogen in the cosmos community, how might ETI respond? Prior to colonizing Mars, humankind should alter its consciousness and conduct on Earth, and conserve its planet home.     

厌恶情绪与消费者行为

厌恶与其他消极情绪存在差异, 不同类型的厌恶也不完全相同。可以采用不同的方法来诱发消费者的不同类型的厌恶。产品与服务、宣传、组织行为等均可能导致消费者产生不同类型的厌恶。不同类型的厌恶又会影响消费者行为, 如产品评价、购买意向、支付意愿、延迟决策、口碑、产品消费等。未来可以对厌恶与其他消极情绪对消费者行为影响的差异、不同类型的厌恶对消费者行为影响的差异、厌恶的前因变量与结果变量进行更深入的探索。     

Sex,germs, and health: pathogen-avoidance motives and health-protective behaviour

Objective: Recent work suggests that the psychology of pathogen-avoidance has wide-reaching effects on how people interact with the world. These processes – part of what has been referred to as the behavioural immune system – are, in a way, our ‘evolved’ health psychology. However, scholars have scarcely investigated how the behavioural immune system relates to health-protective behaviours. The current research attempts to fill this gap.

Design: Across two cross-sectional studies (N = 386 and 470, respectively), we examined the relationship between pathogen-avoidance motives and health-protective behaviour.

Outcome Measures: The studies used self-reported measures of attitude and intention as indicators of health-protective behaviour.

Results: Data collected in Study 1 revealed that pathogen-avoidance motivation related to participants’ attitude and intention towards sexually transmitted infections screening. High levels of pathogen-avoidance motivation were also related to having had fewer sexual partners, which partially mediated the effect of pathogen-avoidance variables on testing motivation. Study 2 extended these findings by showing moderate associations between pathogen-avoidance motivation and a broad range of health-protective behaviours, including but not limited to pathogen-related health concerns.

Conclusion: We argue that understanding and targeting pathogen-avoidance psychology can add novel and important understanding of health-protective behaviour.     

行为免疫系统理论及其研究:新视野下的再考察

行为免疫系统理论认为, 为了应对流行病威胁, 人类进化出了一套特殊的行为反应倾向, 包括对疾病线索的警觉、厌恶, 对健康配偶的偏好, 对外群体的排斥, 对集体主义的推崇等。已有研究主要从宏观(群体)和微观(个体)两个水平开展, 虽然有大量研究结果支持该理论, 但也存在不少不一致甚至相反的发现。研究方法、理论基础和现代适用性等方面的不足可能是出现这种情况的原因。未来研究需克服上述问题, 并进一步拓展该理论的研究内容, 检验理论和相关研究的边界, 探讨行为免疫背后的生理机制等。     

The Behavioral Immune System Shapes Partisan Preferences in Modern Democracies: Disgust Sensitivity Predicts Voting for Socially Conservative Parties

While there is growing interest in the relationship between pathogen-avoidance motivations and partisanship, the extant findings remain contradictory and suffer from a number of methodological limitations related to measurement and internal and external validity. We address these limitations and marshal the most complete test to date of the relationship between the behavioral immune system and partisanship, as indexed by which party people identify with and vote for. Using a unique research design, including multiple well-powered, nationally representative samples from the United States and Denmark collected in election and nonelection contexts, our study is the first to establish in cross-national data a consistent, substantial, and replicable connection between deep-seated pathogen-avoidance motivations and socially conservative party preferences across multiple validated measures of individual differences in disgust sensitivity and using large representative samples. We explore the relative contribution of the pathogen-avoidance model and sexual strategies for accounting for this relationship.
