Propositional knowledge and know-how

This paper is roughly in two parts. The first deals with whether know-how is constituted by propositional knowledge, as discussed primarily by Gilbert Ryle (1949) The concept of mind. London: Hutchinson, Jason Stanley and Timothy Williamson (2001). Knowing how. Journal of Philosophy, 98, pp. 411–444 as well as Stephen Hetherington (2006). How to know that knowledge-that is knowledge-how. In S. Hetherington (Ed.) Epistemology futures. Oxford: Oxford University Press. The conclusion of this first part is that know-how sometimes does and sometimes does not consist in propositional knowledge. The second part defends an analysis of know-how inspired by Katherine Hawley’ (2003). Success and knowledge-how. American Philosophical Quarterly, 40, pp. 19–31, insightful proposal that know-how requires counterfactual success. I conclude by showing how this analysis helps to explain why know-how sometimes does and sometimes does not consist of propositional knowledge.     

基于视觉传播理论探索视觉素养与读片技能的整合

视觉素养是"读图"时代人们的基本文化素养,鉴于医学影像学的特点和要求,影像诊断学专业学生必须拥有良好的视觉素养。本文从视觉素养概念、视觉基本理论以及视觉素养培养的策略等方面探索了视觉素养与读片技能的整合。作者建议在影像诊断学中,应讲授有关视觉素养的基本知识。     

Using Neuroimaging to Measure Mental Representations: Finding Color-OpponentNeurons in Visual Cortex

To date, most neuroimaging studies have tried to localize large regions in the brain that are responsible for specific behaviors or mental operations. Psychological theory, however, is more concerned with the nature of mental functions than with the locations of their neural substrates. This article reviews work that moves beyond functional anatomy to measure how color is represented by neurons in visual cortex. The general approach has three basic steps: First, the areas under investigation are localized in the brain. Second, responses of these areas are measured to sets of systematically varying stimuli, designed to uncover the nature of cortical representations. Third, the neuroimaging data are compared with behavioral data measured with the same stimuli. Results obtained using this approach support the hypothesis that primary visual cortex contains color-opponent neurons that support perception.     

视觉观点采择的发生发展及其影响因素

通过总结视觉观点采择的概念和研究范式,概括发展心理学和比较心理学中视觉观点采择演化发生和个体发展的已有研究,分析视觉观点采择与心理理论的关系及语言和文化等影响因素,指出将来的研究需要归纳测验不同水平视觉观点采择的一系列研究范式,系统考察不同物种间视觉观点采择的演化发生过程,还可将不同水平的实验范式与脑成像研究相结合来考察视觉观点采择的脑神经机制,并关注影响视觉观点采择发展的因素.     

多级计分认知诊断计算机化自适应测验的新选题方法

认知诊断计算机化自适应测验（Cognitive Diagnosis Computerized Adaptive Testing, CD-CAT）是认知诊断评估和计算机化自适应测验两者的结合,兼具认知诊断和自适应测验的特点。目前,针对CD-CAT的研究几乎都集中在0-1二级计分的数据。然而,在教育和心理评估的实际应用中,存在大量的多级计分的数据。因此,本研究探讨了多级计分CD-CAT（Polytomous CD-CAT, PCD-CAT）的实现技术,并提出了2种新的选题方法。通过模拟实验比较了新选题方法和传统选题方法在PCD-CAT的效果,结果表明：在定长PCD-CAT条件下,2种新选题方法的模式分类准确率是最高的,而在非定长PCD-CAT条件下,2种新方法的测验效率也是最高的。

Crowdsourcing and personality measurement equivalence: A warning about countries whose primary language is not English

In the search to find cheaper, faster approaches for data collection, crowdsourcing methods (i.e., online labor portals that allow independent workers to complete surveys for compensation) have risen in popularity as a tool for personality researchers, despite a lack of evidence regarding the equivalence of crowdsourcing with traditional data collection methods. The purpose of this study was to evaluate crowdsourcing as a data collection tool by examining the measurement equivalence of crowdsourced data (i.e., from Amazon.com’s MTurk) with more traditional samples (i.e., an undergraduate sample and a sample of organizational employees). Our results (using a popular measure of Big Five personality) provided evidence of measurement equivalence across all three samples, with one important exception: crowdsourced data (from MTurk) only exhibited measurement invariance with traditional data collection methods when responses were restricted to participants from native-English speaking countries. Although MTurk appears to be an easy, cost-effective data collection tool, our results suggest that MTurk data are similar to traditionally-collected data only when the MTurk sample is restricted to IP addresses from English-speaking countries.     

Exploring the interactions underlying flow states: A connecting analysis of flow occurrence in European Tour golfers

ObjectivesResearch to date has identified a range of factors suggested to facilitate flow states in sport. However, less attention has focused on how exactly those facilitating factors influence the occurrence of flow. Therefore, this study aimed to explore the specific ways in which such facilitators influenced flow occurrence in European Tour golfers.DesignQualitative design.MethodTen full-time golfers from the European Tour (M age = 37; SD = 13.08) participated in semi-structured interviews investigating the occurrence of their flow states. Data were interpreted using an iterative process of thematic and connecting analyses.ResultsTen facilitators of flow were identified, of which commitment and the caddie have not been reported previously. Twenty four connecting links were identified in the data, through which the caddie, effective preparation, and high-quality performance appeared to be most influential for flow occurrence. Confidence and concentration also emerged as key constructs underlying the flow experience in this setting.ConclusionA central contribution of this study is the identification of ways in which facilitating factors could influence flow occurrence in elite golf. This process adds detail to understanding of flow occurrence, and moves beyond simply identifying factors which are associated with the experience. As such, connecting analysis is proposed as an additional strategy for qualitatively investigating flow occurrence in sport. Results are discussed in relation to previous literature, and recommendations are identified for researchers, athletes, coaches and practitioners.     

How Do Australian University Students Understand Adulthood?

The understanding of modern young people's conceptions of adulthood has largely been informed and constructed through the lens of the theory of emerging adulthood. As a consequence, a relatively unquestioned belief is that there has been a trend towards the gradual development of internal, subjective characteristics and away from the attainment of traditional adult roles in emerging adults' conceptions of adulthood. Using both quantitative and qualitative methods, we surveyed Australian university students about their understanding of what it means to be an adult. Exploratory factor analysis of the Criteria for Adulthood Scale emphasised family capacities, demographic markers, norm compliance, and “novelty of adulthood,” while qualitative themes emphasised both personal and environmental characteristics. We suggest that rather than being independent, individual development and broad social‐environmental trends are likely to be interrelated, and to develop in response to each other over time.     

颜色对基于时间的视觉选择的影响

旨在探讨颜色属性对基于时间的图形预览搜索的影响及其机制。实验采用视觉标记实验范式的变式考察三种颜色的图形刺激的预览收益。结果发现:搜索与旧干扰物相同颜色的靶子和搜索新异颜色刺激并未出现反应时的差异,而且,两者都快于搜索与新干扰物颜色相同的靶子。这说明,在图形刺激的预览搜索中,观察者没有主动抑制旧干扰物的颜色,而是主动加工新出现的刺激。还探讨了基于颜色标记的抑制机制和主动非抑制机制。
