神经网络模型对内隐学习的探索

近几年来,研究者们借助人工神经网络模型的方法对内隐学习研究中突出的争论性问题进行了新的探索。针对内隐学习的无意识问题,模拟研究发现确实存在一种无意识的内隐学习,然而这种无意识加工的发生与否要取决于规则的难易程度;针对内隐学习的抽象性问题,人工神经网络模型所主张的分布式概率表征能较好地加以解释。可见,神经网络模型的原理和模拟研究可能为真正地解决内隐学习的无意识性和抽象性等目前争论较多的领域提供一个全新的视角和研究方向。     

The Space–Time Congruency Effect: A Meta‐Analysis

Several reaction time (RT) studies report faster responses when responses to temporal information are arranged in a spatially congruent manner than when this arrangement is incongruent. The resulting space–time congruency effect is commonly attributed to a culturally salient localization of temporal information along a mental timeline (e.g., a mental timeline that runs from left to right). The present study aims to provide a compilation of the published RT studies on this time–space association in order to estimate the size of its effect and the extent of potential publication bias in this field of research. In this meta‐analysis, three types of task are distinguished due to hitherto existing empirical findings. These findings suggest that the extent to which time is made relevant to the experimental task has a systematic impact on whether or not the mental timeline is activated. The results of this meta‐analysis corroborate these considerations: First, experiments that make time a task‐relevant dimension have a mean effect size of d = 0.46. Second, in experiments in which time is task irrelevant, the effect size does not significantly deviate from zero. Third, temporal priming studies have a surprisingly high mean effect size of d = 0.47, which, however, should be adjusted to d = 0.36 due to publication bias.     

Choosing normative properties: a reply to Eklund’s Choosing Normative Concepts

ABSTRACT

The literature surrounding Horgan and Timmons’s Moral Twin Earth scenarios has focused on whether such scenarios present a metasemantic problem for naturalist realists. But in Choosing Normative Concepts, Eklund uses a similar scenario to illuminate a novel, distinctly metaphysical problem for normative realists of both naturalist and non-naturalist stripes. The problem is that it is not clear what (if anything) would suffice for the sort of ardent realist view that normative realists have in mind – the view that reality itself favors certain ways of acting and valuing. Eklund then offers a metasemantic view that he thinks can provide the best solution to this problem. In this reply to Eklund, I argue that Eklund’s treatment of the problem and his solution re-entangle metaphysical and metasemantic issues that ought to be kept separate. I also argue that there is a purely metaphysical solution to the problem at hand, which Eklund’s own solution seems to implicitly rely upon. While these criticisms do not suggest that Eklund’s positive view is false, they do undermine some of the broader lessons that Eklund hopes to draw from the view.     

道德概念的隐喻表征——从红白颜色、左右位置和正斜字体的维度

随着具身认知的兴起和发展,道德隐喻的研究焕发新活力。在此背景下,本研究从红白颜色、左右位置和正斜字体三个维度考察道德概念的隐喻表征。实验1的结果显示,红白颜色可能并不与道德概念存在隐喻表征。实验2表明,左右位置与道德概念交互作用显著,左边、右边位置分别与不道德概念、道德概念存在一致的隐喻表征。实验3发现,正斜字体对道德概念的判断具有干扰作用,正体字与道德词汇隐喻表征一致,斜体字与不道德词汇隐喻表征一致。研究表明:左右位置、正斜字体与道德概念存在一定的隐喻联结。     

Conceptual engineering for mathematical concepts

In this paper I investigate how conceptual engineering applies to mathematical concepts in particular. I begin with a discussion of Waismann’s notion of open texture, and compare it to Shapiro’s modern usage of the term. Next I set out the position taken by Lakatos which sees mathematical concepts as dynamic and open to improvement and development, arguing that Waismann’s open texture applies to mathematical concepts too. With the perspective of mathematics as open-textured, I make the case that this allows us to deploy the tools of conceptual engineering in mathematics. I will examine Cappelen’s recent argument that there are no conceptual safe spaces and consider whether mathematics constitutes a counterexample. I argue that it does not, drawing on Haslanger’s distinction between manifest and operative concepts, and applying this in a novel way to set-theoretic foundations. I then set out some of the questions that need to be engaged with to establish mathematics as involving a kind of conceptual engineering. I finish with a case study of how the tools of conceptual engineering will give us a way to progress in the debate between advocates of the Universe view and the Multiverse view in set theory.     

Not quite neo-sentimentalism

The view that some evaluative concepts are identical to some affective concepts naturally falls out of neo-sentimentalism, but it is unstable. This paper argues for a view of evaluative concepts that is neo-sentimentalist in spirit but which eschews the identity claim. If we adopt a Peacockean view of concepts, then we should think of some evaluative concepts as having possession conditions that are affective in some way. I argue that the best version of this thought claims that possessing those concepts requires being rationally compelled to form evaluative beliefs in response to certain emotions.     

Cultural conceptions of a bereavement-related illness in a South African indigenous community

This study explored cultural conceptions of a bereavement-related illness among elderly (aged 34–85yrs) Northern Sotho-speaking people in Limpopo province. The participants (n = 14, females = 50%, mean age = 59 years, SD: 13.7 years) were purposively selected and interviewed using in-depth interviews. Data were analysed using Hycner’s adapted phenomenological method. Three themes emerged from the analysis: debilitating and life-threatening symptoms of the illness; aetiology explained by ritual taboo violations; and management of the illness through ritual cleansing. The cleansing process incorporates the administration of traditional herbs. The findings suggest bereavement-related illness in an African cultural community to be explained by their cultural concept of distress understandings.     

Auditory spatial concepts in blind football experts

ObjectivesWe compared the spatial concepts given to sounds' directions by blind football players with both blind non-athletes and sighted individuals.MethodParticipants verbally described the directions of sounds around them by using predefined spatial concept labels, under two blocked conditions: 1) facing front, 2) pointing with the hand towards the stimulus.ResultsBlind football players categorized the directions more precisely (i.e., they used simple labels for describing the cardinal directions and combined labels for the intermediate ones) than the other groups, and their categorization was less sensitive to the response conditions than blind non-athletes. Sighted participants' categorization was similar to previous studies, in which the front and back regions were generally more precisely described than the sides, where simple labels were often used for describing directions around the absolute left and right.ConclusionsThe differences in conceptual categorization of sound directions are a) in sighted individuals, influenced by the representation of the visual space b) in blind individuals, influenced by the level of expertise in action and locomotion based on non-visual information, which can be increased by auditive stimulation provided by blind football training.     

3~5岁幼儿权力概念多重隐喻的认知发展

为考察3~5岁幼儿“权力”概念的大小、垂直空间和重量多重隐喻的认知发展进程, 研究采用了将权力人物和无权力人物图片放置大圆形或小圆形、垂直空间的上方框或下方框和不平衡跷跷板重端或轻端的图片迫选任务。通过3个实验及综合分析发现：3岁幼儿尚不具备权力隐喻理解能力; 4岁是幼儿权力隐喻理解能力的重要发展时期, 具备正极权力概念的隐喻理解能力, 建立起有权力为“大、高、重”的多重隐喻联结; 5岁幼儿的权力隐喻理解能力进一步增强, 已具备较完整的多重隐喻理解能力, 建立起有权力为“大、高、重”、无权力为“小、下、轻”的多重隐喻联结。3~5岁幼儿“权力”概念的大小、垂直空间和重量多重隐喻理解能力同步发展, 不受隐喻靶域习得时间早晚的影响。系列研究表明, 学龄前幼儿的权力隐喻理解能力发展趋势符合隐喻一致性理论, 隐喻表征的产生并非“有或无”的模式, 而是“渐进”呈现发展。
