Moral expertise

We offer a theory of moral expertise based on an updated version of the Thomistic concept of habitus. We maintain that mature moral control arises from internalized standards of belief married to corresponding actions; the result is moral expertise. Beliefs and actions (conceptualized as habitus) coalesce in a moral identity, which is then sustained by the beliefs and actions that comprise the habitus; what we do affects who we are and what we believe, just as what we believe guides what we do. In support of these claims, we examine recent research on moral judgment, moral identity, and moral emotions.     

Where Philosophical Intuitions Come From

Little is known about the aetiology of philosophical intuitions, in spite of their central role in analytic philosophy. This paper provides a psychological account of the intuitions that underlie philosophical practice, with a focus on intuitions that underlie the method of cases. I argue that many philosophical intuitions originate from spontaneous, early-developing, cognitive processes that also play a role in other cognitive domains. Additionally, they have a skilled, practiced, component. Philosophers are expert elicitors of intuitions in the dialectical context of professional philosophy. If this analysis is correct, this should lead to a reassessment of experimental philosophical studies of expertise.     

情绪音乐影像库的初步编制与评定

音乐表演影像材料的情绪诱发功能有音乐和影像的共同优势,但目前缺乏以音乐表演为内容的情绪音乐影像库。试图建立可供相关研究使用的情绪音乐影像系统。根据前期研究使用过的材料、相关研究结果及音乐专业人士的建议,收集分别表达愤怒、恐惧、悲伤和开心的音乐,包括歌剧、交响乐、民乐等,剪辑为30秒左右的片段,非音乐专业被试对材料的情绪类型和强度进行评定,最终筛选出能有效诱发目标情绪的64条音乐影像材料。未来可在测量指标的客观性和审美性及被试和音乐材料的样本量两方面改进。     

A dot that went for a walk: People prefer lines drawn with human-like kinematics

A dominant theory of embodied aesthetic experience (Freedberg & Gallese, 2007, Trends in Cognitive Sciences, 11, 197) posits that the appreciation of visual art is linked to the artist’s movements when creating the artwork, yet a direct link between the kinematics of drawing actions and the aesthetics of drawing outcomes has not been experimentally demonstrated. Across four experiments, we measured aesthetic responses of students from arts and non-arts backgrounds to drawing movements generated from computational models of human writing. Experiment 1 demonstrated that human-like drawing movements with bell-shaped velocity profiles (Sigma Lognormal [SL] and Minimum Jerk [MJ]) are perceived as more natural and pleasant than movements with a uniform profile, and in both Experiments 1 and 2 movements that were perceived as more natural were also preferred. Experiment 3 showed that this effect persists if lower-level dynamic stimulus features are fully matched across experimental and control conditions. Furthermore, aesthetic preference for human-like movements were associated with greater perceptual fluency in Experiment 3, evidenced by unbiased estimations of the duration of natural movements. In Experiment 4, line drawings with visual features consistent with the dynamics of natural, human-like movements were preferred, but only by art students. Our findings directly link the aesthetics of human action to the visual aesthetics of drawings, but highlight the importance of incorporating artistic expertise into embodied accounts of aesthetic experience.     

Motivation for Conflict Among Chinese University Students: Effects of Others' Expertise and One's Own Confidence on Engaging in Conflict

Abstract

Researchers (A. C. Amason, 1996; D. H. Gruenfeld, 1995; K. A. Jehn, 1995, 1997; M. A. Rahim, 1989; M. A. Rahim & A. A. Blum, 1994; D. M. Schweiger, W. R. Sandberg, & P. L. Rechner, 1989; P. E. Tetlock, D. Armor, & R. S. Peterson, 1994) have documented the value of conflictual discussions for solving problems, but few have explored the conditions under which people are motivated to engage in controversy (K. A. Jehn, C. Chadwick, & S. M. B. Thatcher, 1997). Some (M. Van Berklom & D. Tjosvold, 1981) have hypothesized that high expertise and a competitive social context arouse concerns about defending one's position and challenging the opposing one. In the present study, Chinese university students in Hong Kong who expected to disagree with an expert, compared with those who did not expect to disagree with an expert, had less confidence, felt less knowledgeable about their position, and selected an agreeable discussant. Consistent with the idea of maintaining distance from those in power, the participants were reluctant to disagree directly with someone with greater expertise.     

When should I trust my gut? Linking domain expertise to intuitive decision-making effectiveness

Despite a growing body of scholarship on the concept of intuition, there is a scarcity of empirical research spotlighting the circumstances in which intuitive decision making is effective relative to analytical decision making. Seeking to address this deficiency, we conducted two laboratory studies assessing the link between domain expertise (low versus high) and intuitive decision-making effectiveness. These studies involved non-decomposable tasks across divergent expertise domains: basketball in Study 1 and designer handbag authentication in Study 2. Across both studies, and consistent with our overarching hypothesis, we found that the effectiveness of intuition relative to analysis is amplified at a high level of domain expertise. Taken together, our results demonstrate the importance of domain expertise in intuitive decision making and carry a number of theoretical and practical implications.     

The Price of a Piece of Cheese: Value from Fit Between Epistemic Needs and a Learning Versus an Outcome Focus

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Modeling Lifelong Learning: Collaborative Teaching across Disciplinary Lines

Most courses in colleges and universities are taught by only one instructor. This is often necessitated by the financial exigencies of educational institutions, but is also due to an academic tradition in which the ideal is a single expert teaching in a single discipline. The rapidly changing realities of both the higher education and job markets, however, have called the traditional ideal into question. Interdisciplinary collaborative teaching is one way to adapt to the needs of twenty‐first‐century students, by modeling lifelong learning for students and inviting instructors to be more deliberately reflective about disciplinary assumptions, learning styles, and pedagogies.
