Feature Statistics Modulate the Activation of Meaning During Spoken Word Processing

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature‐based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in (distinctiveness/sharedness) and likelihood of co‐occurrence (correlational strength)—determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech‐to‐meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time‐sensitive co‐occurrence‐driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general‐to‐specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation.     

Making Sense of Dynamic Systems: How Our Understanding of Stocks and Flows Depends on a Global Perspective

Stocks and flows (SF) are building blocks of dynamic systems: Stocks change through inflows and outflows, such as our bank balance changing with withdrawals and deposits, or atmospheric CO₂ with absorptions and emissions. However, people make systematic errors when trying to infer the behavior of dynamic systems, termed SF failure, whose cognitive explanations are yet unknown. We argue that SF failure appears when people focus on specific system elements (local processing), rather than on the system structure and gestalt (global processing). Using a standard SF task (n = 148), SF failure decreased by (a) a global as opposed to local task format; (b) individual global as opposed to local processing styles; and (c) global as opposed to local perceptual priming. These results converge toward local processing as an explanation for SF failure. We discuss theoretical and practical implications on the connections between the scope of attention and understanding of dynamic systems.     

Second special section on religion and territorial politics in southern Europe

The three articles included in this second special section devoted to the interactions between religion and territorial politics in southern Europe continue the underlying research questions about the multiscalar interactions between religious mobilisation and policymaking, focusing on different denominations and scales of observations. The three articles point out three relevant elements for the analysis of religion and local politics. First, they show how contextualised exogenous factors influence the structures of opportunities for religions in the public and the political spheres. Second, they inchoately reveal the weakness of simplistic readings of the secularisation thesis. Third, they evidence the importance of a local and localised approach in analysing the relationships between religion and politics.     

工程设计的伦理意蕴

工程设计不是单独的个人行为,而是富有文化意蕴的社会性的系统行动。它以生态保护为基本伦理原则,以以人为本为主要评价标准。工程设计伦理的主要特征是科学精神与人文精神的有机结合,价值理性挑战工具理性的集中体现,环境伦理、技术伦理与社会伦理的融合统一。     

反馈评估的局部背景依赖效应：ERP研究

人脑对反馈的评估依赖于其所处背景。但是只能依赖整体背景(整个组块的结果范围), 还是可以依赖局部背景(单个试次的结果范围)进行评估, 目前并不清楚。本研究通过获益/损失线索操纵所在试次的反馈背景, 探讨反馈评估仅依赖整体背景, 还是可延伸到局部水平。25名被试参与实验。结果发现, 背景试次间变化时, 在获益背景下, ￥0 (负反馈)比+ ￥4 (正反馈)引发更负的FRN (feedback-related negativity); 在损失背景下, - ￥4 (负反馈)比￥0 (正反馈)引发更负的FRN。这一结果说明反馈评估以某线索背景中可能的结果为参考对象, FRN的背景依赖可以延伸到局部水平。结合前人研究, 推测任务类型和反馈真实性会调节背景依赖水平。在含真实反馈的主动性任务中, FRN的背景依赖效应可延伸至局部水平。     

Gender and appearance accuracy: Women’s advantage over men is restricted to dress items

Which aspects of people’s appearance do women remember better than men? Women were predicted to remember the dress-related items but not the physical characteristics of targets more accurately than men, given that the former might be a more female-relevant domain of interest among perceivers. Participants watched a videotaped target and then completed a surprise test of their memory for her/his appearance. Men were as accurate as women at remembering the target’s physical features but less accurate than woman at recalling what the target was wearing. Discussion focuses on the implications of these findings for eyewitness accuracy.     

Empirical Propositions and the Change of Language-Games

People unavoidably provide reasons for their words and deeds when reasoning in a language-game.Wittgenstein thinks that when people in different language-games argue with one other,they insist on adopting a doubtful attitude toward the reasons provided by the other side.His use of the term "language-game" here is a metaphor,and implies that people in different cultures can scarcely reason with one another.Indeed,according to Wittgenstein's consideration of concepts of logic in On Certainty,language-games are incompatible with one another because their internal logic and reasons are different from each other.However,in his discussion of empirical propositions Wittgenstein has also shown us the possibility that the intemal reasons of one language-game can transmit beyond its own borders and be valid in another language-game.

Scientific Peer Review: A Case Study From Local And Global Analyses.

The dialog between Staddon (2001, 2004) and Baum (2004) raises general questions about the nature of scientific peer review. Their dialog displays effects on peer review of differences of opinion about the relative merits of local and global analyses. Baum (1995, 1997, 2001, 2002) favors global analyses as a paradigm different, newer, and better than the local, dynamic, real‐time approach that plays a significant role in Staddon (2001). According to the Kuhnian perspective (Kuhn, 1996) Baum advocates, we can better understand his review of Staddon (2001) by considering the implications for it of his commitment to the idea that a global analysis is a superior scientific paradigm. This commentary examines some characteristics of local and global analyses, as well as some of their possible implications for peer review in the context of a reviewer's belief in the Kuhnian idea of incommensurability: According to this idea, a reviewer who either is, or who believes he is, from one paradigm is unlikely, for better or worse, to understand or perhaps even tolerate work from a different paradigm. It is recommended that a process be developed to encourage “truth in peer reviewing” to reduce possible conflicts of interest embedded in the current conception of scientific peer review.     

The change probability effect: incidental learning, adaptability, and shared visual working memory resources

Statistical properties in the visual environment can be used to improve performance on visual working memory (VWM) tasks. The current study examined the ability to incidentally learn that a change is more likely to occur to a particular feature dimension (shape, color, or location) and use this information to improve change detection performance for that dimension (the change probability effect). Participants completed a change detection task in which one change type was more probable than others. Change probability effects were found for color and shape changes, but not location changes, and intentional strategies did not improve the effect. Furthermore, the change probability effect developed and adapted to new probability information quickly. Finally, in some conditions, an improvement in change detection performance for a probable change led to an impairment in change detection for improbable changes.
