创造性思维的社会文化基础

创造性思维作为创造性的内核, 是个体在一定社会文化背景上产生新颖独特且实用观点或产品的思维形式。文章基于社会文化的三层次模型, 分别从文化观念、文化活动或经历以及文化工具三个层面, 围绕人性价值观、中庸取向、非价值性文化传统、海外旅居、多语种学习、以及文化工具所涵盖的文化规则、符号和实物七个方面阐述了社会文化对创造性思维的影响。未来研究有必要在此基础上继续从文化与社会因素的依存性、个体差异控制、文化和创造性思维的类型差异以及多重研究取向协作四方面深入。     

Representationalism and the conceivability of inverted spectra

Most philosophers who have endorsed the idea that there is such a thing as phenomenal content—content that supervenes on phenomenal character—have also endorsed what I call Standard Russellianism. According to Standard Russellianism, phenomenal content is Russellian in nature, and the properties represented by perceptual experiences are mind-independent physical properties. In agreement with Sydney Shoemaker [Shoemaker, S. (1994). Philosophy and Phenomenological Research, 54 249–314], I argue that Standard Russellianism is incompatible with the possibility of spectrum inversion without illusion. One defense of Standard Russellianism is to hold that spectrum inversion without illusion is conceivable but not in fact possible. I argue that this response fails. As a consequence, either phenomenal content is not Russellian, or experiences do not represent mind-independent physical properties.     

Intentionalism and Change Blindness

According to reductive intentionalism, the phenomenal character of a conscious experience is constituted by the experience's intentional (or representational) content. In this article I attempt to show that a phenomenon in visual perception called change blindness poses a problem for this doctrine. Specifically, I argue that phenomenal character is not sensitive, as it should be if reductive intentionalism is correct, to fine-grained variations in content. The standard anti-intentionalist strategy is to adduce putative cases in which phenomenal character varies despite sameness of content. This paper explores an alternative antiintentionalist tack, arguing, by way of a specific example involving change blindness, that content can vary despite sameness of phenomenal character.

Threat in dreams: an adaptation?

Revonsuo's influential Threat Simulation Theory (TST) predicts that people exposed to survival threats will have more threat dreams, and evince enhanced responses to dream threats, compared to those living in relatively safe conditions. Participants in a high crime area (South Africa: n=208) differed significantly from participants in a low crime area (Wales, UK: n=116) in having greater recent exposure to a life-threatening event (chi([1,N=186])(2)=14.84, p<.00012). Contrary to TST's predictions, the SA participants reported significantly fewer threat dreams (chi([1,N=287])(2)=6.11, p<.0134), and did not differ from the Welsh participants in responses to dream threats (Fisher's Exact test, p=.2478). Overall, the incidence of threat in dreams was extremely low-less than 20% of dreams featured realistic survival threats. Escape from dream threats occurred in less than 2% of dreams. We conclude that this evidence contradicts key aspects of TST.     

Shooting the messenger won’t change the news

Malcolm-Smith, Solms, Turnbull and Tredoux [Malcolm-Smith, S., Solms, M., Turnbull, O., & Tredoux, C. (2008). Threat in dreams: An adaptation? Consciousness and Cognition, 17, 1281–1291.] conducted a rigorous study that sampled two populations differentially exposed to threat in real life, and found that critical predictions from the Threat Simulation Theory of dreams [Revonsuo, A. (2000a). The reinterpretation of dreams: An evolutionary hypothesis of the function of dreaming. Behavioral and Brain Sciences, 23, 877-901.; Revonsuo, A. (2000b). Did ancestral humans dream for their lives? Behavioral and Brain Sciences, 23, 1063–1082.] were not supported. Specifically, we found no evidence of increased realistic threats to physical survival or enhanced threat avoidance in the dreams of those from the exposed population. Revonsuo and Valli’s [Revonsuo, A., & Valli, K. (2008). How to test the threat simulation theory. Consciousness and Cognition, 17, 1292-1296.] commentary on our study argues that the methods we used are so flawed as to render the results meaningless. In this response article, we address the criticisms raised in their commentary.     

In Defence of Non-conceptual Content

In recent times, Evans’ idea that mental states could have non-conceptual contents has been attacked. McDowell (Mind and World, 1994) and Brewer (Perception and reason, 1999) have both argued that that notion does not have any epistemological role because notions such as justification or evidential support, that might relate mental contents to each other, must be framed in conceptual terms. On his side, Brewer has argued that instead of non-conceptual content we should consider demonstrative concepts that have the same fine grainess of non-conceptual contents while having conceptual structure. In what follows I will argue that, first, that the notion of demonstrative concept is not viable and, second, that there is an epistemological role for non-conceptual content.

论庄子“万物一齐”的生态审美观

当先秦诸子大都以人的理解为中心去看待人与自然万物的存在方式,认为万物只是相对于人来说才具有存在的价值和意义时,庄子站在古典存在论的立场上提出了含有生态审美智慧的“万物一齐”观,即“休乎天钧”的生态和谐理念、“为是不用而寓诸庸”的生态价值观念、“万物与我为一”的生态共生气象。其“万物一齐”的生态审美观所蕴涵的万物平等共生、放弃自我中心、无用之用等观念有助于当代的生态伦理和生态实践建设。

三维物体识别的心理表征：角度依赖还是角度独立

“物体识别是角度独立还是角度依赖”的问题一直存在着争议。以物体为中心理论认为是角度独立, 以观察者为中心理论认为是角度依赖。研究参照物体识别的“小几何体”思想自制实验材料, 采用启动范式, 在两个实验中通过考察结构信息和视图信息对物体识别的影响, 揭示物体识别的心理表征。结果发现: (1)形状信息和类别空间关系信息影响物体识别, 表明以物体为中心理论对物体识别表征机制解释的合理性; (2)角度信息可能独立于形状信息表征, 深度旋转方式下的识别成绩优于平面旋转, 表明以观察者为中心理论能够更好地解释三维物体识别的深度旋转现象。研究结果为物体识别理论的融合提供了实证依据。     

War-Related Dream Themes in Germany from 1956 to 2000

Based on the continuity hypothesis of dreaming, the effects of World War II on the dreams of German persons have been studied. The present study included four representative samples from 1956 to 2000 (repeated cross-sectional surveys). Although a decline of war-related dream themes over time was found, the heightened rate of these themes in the oldest age group (60 years and older) in the year 2000 indicate the long-lasting effect of emotionally salient life experiences on dreams. The present findings indicate that the method of dream content analysis is a very informative approach to study the effects of political events on the inner life of people and, thus, of value for the field of political science.
