Reasoning through doing. Epistemic mediators in scientific discovery

The recent epistemological and cognitive studies concentrate on the concept of abduction, as a means to originate and refine new ideas. Traditional cognitive science and computational accounts concerning abduction aim at illustration discovery and creativity processes in terms of theoretical and “internal” aspects, by means of computational simulations and/or abstract cognitive models. I will illustrate in this paper that some typical internal abductive processes are involved in scientific reasoning and discovery (for example through radical innovations). Nevertheless, especially concrete manipulations of the external world constitute a fundamental passage in science: by a process of manipulative abduction it is possible to build prostheses (epistemic mediators) for human minds, by interacting with external objects and representations in a constructive way. In this manner it is possible to create implicit knowledge through doing and to produce various opportunity to find, for example, anomalies and fruitful new risky perspectives. This kind of embodied and unexpressed knowledge holds a key role in the subsequent processes of scientific comprehension and discovery.     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。     

Discovering forgiveness through empathy: implications for couple and family therapy

This article explores the concept of forgiveness in the context of couple and family therapy. Forgiveness is described as a complex psychological and relational process that is more a discovery via understanding and empathy than an act of will. Empathy is related to emotional intelligence, and the developmental and relational benefits of both are discussed. A rationale for viewing forgiveness in a contextual (family of origin), historical and relational attachment paradigm is offered. Relevant clinical cases illustrate the process of forgiveness as discovery in the context of an empathic relational environment where ambivalence is anticipated and respected.

科学心理学的观念及其范畴含义解析

关于心理学作为科学的观念或理想普遍兴起于19世纪下半叶,正是对这个观念或理想的百余年历史的追求和实践,塑造了现代意义上的科学心理学及其历史作为整体的基本面貌,并决定了科学心理学观念的两种范畴含义及其差异,具体表现为在心理学作为科学的整体背景中它的现象学传统或道路与它的科学主义传统或道路之间的对峙关系。历史分析表明,对科学心理学观念的范畴含义的理解和实现,与关于科学观念的范畴含义的探索和理解是密切关联、相互制约的。以人类思维的理论形态的历史转换为背景,我们发现,关于心理学作为科学的观念,只有实现为现象学意义上的科学,才能真正实现它自身;但主流的科学主义传统则要把心理学实现为自然科学,由此实现的科学心理学,只能是对心理学作为科学的观念的异化。     

不同科学创造力个体干扰抑制机制的比较*

选取《科学创造力量表》筛选出高、低科学创造力个体各20名,通过完成经典Stroop色字干扰抑制任务,探讨高、低科学创造力的个体抑制机制的差异。结果发现:在Stroop色字任务上,无论是高科学创造力组还是低科学创造力组,都出现了Stroop干扰效应,但低科学创造力组的Stroop效应更明显;高科学创造力组在字色不一致条件下的错误率显著低于低科学创造力组,但是两组被试在Stroop任务反应时上差异不显著。本研究结果提示高科学创造力个体的认知抑制能力强于低科学创造力个体。     

A sufficient condition for pooling data

We consider the problems arising from using sequences of experiments to discover the causal structure among a set of variables, none of whom are known ahead of time to be an “outcome”. In particular, we present various approaches to resolve conflicts in the experimental results arising from sampling variability in the experiments. We provide a sufficient condition that allows for pooling of data from experiments with different joint distributions over the variables. Satisfaction of the condition allows for an independence test with greater sample size that may resolve some of the conflicts in the experimental results. The pooling condition has its own problems, but should—due to its generality—be informative to techniques for meta-analysis.     

Patterns of abduction

This article describes abductions as special patterns of inference to the best explanation whose structure determines a particularly promising abductive conjecture (conclusion) and thus serves as an abductive search strategy (Sect. 1). A classification of different patterns of abduction is provided which intends to be as complete as possible (Sect. 2). An important distinction is that between selective abductions, which choose an optimal candidate from given multitude of possible explanations (Sects. 3–4), and creative abductions, which introduce new theoretical models or concepts (Sects. 5–7). While selective abduction has dominated the literature, creative abductions are rarely discussed, although they are essential in science. The article introduces several kinds of creative abductions, such as theoretical model abduction, common cause abduction and statistical factor analysis, and illustrates them by various real case examples. It is suggested to demarcate scientifically fruitful abductions from purely speculative abductions by the criterion of causal unification (Sect. 7.1).     

发展:从“硬道理”、“第一要务”到“科学发展”

改革开放的三十年所取得的成功的经验之一,就是找到一个适合中国国情的发展观,即从“发展是硬道理”到“发展是第一要务”从而确立了科学发展观。“发展是硬道理”向我们表明,在发展过程中,“软道理”要服从“硬道理”,无论在何种情况下,我们都是坚持马克思主义历史观,把经济发展看作是社会发展的基础,同时在经济发展中兼顾其他各个方面的发展。     

An Invitation to Behavior Analysts: Review of in Search of Memory: The Emergence of A New Science of Mind by Eric R. Kandel

This fascinating autobiography and multifaceted case history in neuroscience research is accessible to laymen and potentially instructive to working scientists. Kandel takes the reader through his thought processes as he describes experiments that led to some of the past decades'' major neuroscience discoveries (some highlights of which are summarized in the review''s Appendix), and eventually to his Nobel Prize. The review analyzes some of the terminological and conceptual issues that have often inhibited communication between behavior analysts and neuroscientists, with special attention to some of Bennett and Hacker''s admonitions viewed from the perspective of language evolution and linguistics. The review then discusses opportunities for behavior analysts to collaborate with neuroscientists by applying behavioral contingency analysis to help specify the independent variables of neuroscience experiments described by Kandel. Finally, it examines Kandel''s provocative heuristics for locating important research problems, and the lessons that can be gleaned from the book regarding the attributes of potentially great achievers.
