Frege Puzzles and Mental Files

This paper proposes a novel conception of mental files, aimed at addressing Frege puzzles. Classical Frege puzzles involve ignorance and discovery of identity. These may be addressed by accounting for a more basic way for identity to figure in thought—the treatment of beliefs by the believer as being about the same thing. This manifests itself in rational inferences that presuppose the identity of what the beliefs are about. Mental files help to provide a functional characterization of a mind capable of this presupposition, but more must be said to show how it may be rational. I argue that this can be done by drawing out the way in which mental files interact with a thinker's motivational states and so come to have normative functional properties. I show how this theory works better than some other treatments of mental files.     

The Baltimore Mural Project: An approach to threshold concepts in religious studies

The Baltimore Mural Project (BMP) seeks to connect religious studies education to the growing literature on threshold concepts in order to address bottleneck areas in student learning. The project is designed for undergraduate service courses comprised of mostly non‐majors: for example, world religions. Students in these courses often struggle to understand and apply the discipline's unique approaches to the study of religion (i.e. its threshold concepts). Rather than merely memorize certain facts about a religious tradition's myths [or world forming stories], rituals [or embodied disclosures], materials, and so on... students are asked to apply threshold concepts related to religion, art, and the social good to the study of murals in Baltimore. Through a series of project elements (including: field work, photography, digital geomapping, and quantitative, qualitative, and archival research) the BMP helps students who struggle with threshold concepts in religious studies by creatively connecting the more conventional aspects of world religions courses to social justice issues related to mural art in Baltimore. By experientially helping students to make these connections, they are able to find creative routes through otherwise hindering barriers to their learning in religious studies.     

Writing qualitative research — A gathering of selves

This paper is a reflection and discussion on the integration and personal development that may occur when we use ourselves in heuristic research, particularly in the process of writing. It focuses on my writing about a study I undertook with two of my ex‐clients who are brothers, and their journey towards healing, and on their experience of our counselling relationship as part of that journey. As their counsellor, and the main researcher, my story inevitably intermingles and overlaps with theirs. My ‘selves’ as woman, survivor, client, counsellor, researcher (and numerous other selves) and their selves as survivor, man, client and researcher (and many others) are impacted by the collaborative, experiential nature of the work. Issues faced in the writing of a book about the research (Etherington, 2000), such as self‐disclosure and reclaiming my voice, parallel many of my own issues as a client and my clients' issues.     

意识思维和无意识思维对复杂决策的影响

以大学生为被试,以汽车作为实验材料,通过对12条汽车属性信息的操纵,设置出四款优差不同的汽车。通过对汽车的优差选择,探察在属性信息逐条呈现的情况下,有意识思维与无意识思维对复杂决策的影响。研究结果表明:在反应时上,无意识思维下的决策时间要比有意识思维下的决策时间长;在选择的正确率上,有意识思维决策的结果要优于无意识思维决策的结果;在信息回忆量上,有意识思维决策的回忆量要多于无意识思维决策的回忆量,这与无意识思维理论是相违背的。     

Split identity: intransitive judgments of the identity of objects

Identity is a transitive relation, according to all standard accounts. Necessarily, if x = y and y = z, then x = z. However, people sometimes say that two objects, x and z, are the same as a third, y, even when x and z have different properties (thus, x = y and y = z, but x ≠ z). In the present experiments, participants read stories about an iceberg that breaks into two icebergs, one to the east and the other to the west. Many participants (32–54%, in baseline conditions across experiments) decided that both successors were the original iceberg, despite the different spatial locations of the successors. Experiment 1 shows that this tendency is not due to participants failing to understand both to mean both are simultaneously the original. Similarly, Experiment 2 demonstrates that the tendency is not solely due to their interpreting the question to be about properties of the icebergs rather than about the icebergs themselves. Experiments 3 and 4 suggest, instead, that participants may understand Which is the original? to mean Which, in its own right, is entitled to be the original? Emphasizing entitlement increases the number of seemingly intransitive responses, whereas emphasizing the formal properties of identity decreases them.     

Common spatial organization of number and emotional expression: a mental magnitude line

Converging behavioral and neural evidence suggests that numerical representations are mentally organized in left-to-right orientation. Here we show that this format of spatial organization extends to emotional expression. In Experiment 1, right-side responses became increasingly faster as number (represented by Arabic numerals) or happiness (depicted in facial stimuli) increased, for judgments completely unrelated to magnitude. Additional experiments suggest that magnitude (i.e., more/less relations), not valence (i.e., positive/negative), underlies left-to-right orientation of emotional expression (Experiment 2), and that this orientation accommodates to the context-relevant emotion (e.g., happier faces are more rightward when judged on happiness, but more leftward when judged on angriness; Experiment 3). These findings show that people automatically extract magnitude from a variety of stimuli, representing such information in common left-to-right format, perhaps reflecting a mental magnitude line. We suggest that number is but one dimension in a hyper-general representational system uniting disparate dimensions of magnitude and likely subserved by common neural mechanisms in posterior parietal cortex.     

Turn right or turn left? Heuristic of adhering to the direction of destination

It has been found that humans not only tend to avoid the middle routes and prefer the peripheral routes among multiple choices, but also rely on the ‘initial segment strategy’ to select the route. In this paper, we propose a new heuristic which humans apply during route selection: Participants prefer the route whose initial direction lies in the direction of their final destination, while avoiding the route whose initial direction does not. Four maps were designed. The pathways, on different maps, constituted a parallelogram, a rectangle and a square. Pedestrians were instructed to select a route from an origin to a destination on one of the maps. The results confirm the application of the newly proposed heuristic. Other possible factors, such as handedness, route angles and occurrence of turns were excluded. Moreover, the heuristics of deferring decision and relying on initial straightness are not supported.

抽象概念表征的具身认知观

抽象概念是否通过感知经验来表征以及如何被感知经验表征是具身认知面临的一大问题.在抽象概念表征是否具有感知经验基础的问题上,具身认知理论认为抽象概念通过情境模拟或隐喻与感知经验发生联系.在抽象概念如何与感知经验表征发生联系的问题上,概念模拟理论强调情景或运动模拟在抽象概念表征中的直接作用;概念隐喻理论则侧重具体经验或具体经验与抽象概念之间的共同结构关系在抽象概念表征中的间接作用.未来研究应改变概念表征的稳定的心理实体观,从语言和抽象表征的关系、正常儿童和特殊群体的抽象概念表征差异入手,整合不同的具身认知观点.     

Reducing the Linear Perception of Nonlinearity: Use of a Physical Representation

Research shows that while judging accumulations of quantities over time (e.g., money in a bank account or CO₂ in Earth's atmosphere), people assume that the shape of the accumulation is similar to the shape of the inflow (i.e., people rely on a correlation heuristic). Relying on the correlation heuristic is particularly worrisome for Earth's climate, as judging the CO₂ accumulation according to its emissions (inflow) would underestimate the actual (nonlinear) increase. This misperception undermines the seriousness of climate problem and results in wait‐and‐see behavior. We report two experiments where the effectiveness of a physical representation is compared with graphical and text representations in reducing people's underestimation of nonlinear accumulation in different contexts and problems. A physical representation presents an accumulation using a picture that works as a metaphor. In the first experiment, participants drew the shape of an accumulation over time relying on physical or graphical representations in one of two contexts: carbon dioxide and marbles. Although the participants underestimated the accumulation in both contexts, underestimations were reduced in the physical representation compared with the graphical representation. In the second experiment, we extended the evaluation of physical representations against both text and graphical representations in two different climate problems (with linearly increasing or decreasing inflow). Again, underestimations of the accumulation were reduced in the physical representation compared with the other two representations, regardless of the nature of the problem. We discuss implications of using the physical representation for improving people's estimates of nonlinear CO₂ accumulation. Copyright © 2011 John Wiley & Sons, Ltd.
