Modality switching costs emerge in concept creation as well as retrieval

Theories of embodied cognition hold that the conceptual system uses perceptual simulations for the purposes of representation. A strong prediction is that perceptual phenomena should emerge in conceptual processing, and, in support, previous research has shown that switching modalities from one trial to the next incurs a processing cost during conceptual tasks. However, to date, such research has been limited by its reliance on the retrieval of familiar concepts. We therefore examined concept creation by asking participants to interpret modality-specific compound phrases (i.e., conceptual combinations). Results show that modality switching costs emerge during the creation of new conceptual entities: People are slower to simulate a novel concept (e.g., auditory jingling onion) when their attention has already been engaged by a different modality in simulating a familiar concept (e.g., visual shiny penny). Furthermore, these costs cannot be accounted for by linguistic factors alone. Rather, our findings support the embodied view that concept creation, as well as retrieval, requires situated perceptual simulation.     

Social strategies in self-deception

How do people deceive themselves? I argue that although self-deception tends to be conceptualized as something that happens ‘within an individual’, it can also be a process that is distributed across the social context of a self-deceiver. In this paper I will, first, conceptually distinguish different strategies of such ‘social self-deception’. Second, I will incorporate these into the two main conceptualizations of self-deception: intentionalism and deflationism. Finally, I will show how the proposed re-conceptualization of self-deception can be beneficial to conceptual, moral and empirical research.     

Space and Time in the Child's Mind: Evidence for a Cross-Dimensional Asymmetry

What is the relationship between space and time in the human mind? Studies in adults show an asymmetric relationship between mental representations of these basic dimensions of experience: Representations of time depend on space more than representations of space depend on time. Here we investigated the relationship between space and time in the developing mind. Native Greek‐speaking children watched movies of two animals traveling along parallel paths for different distances or durations and judged the spatial and temporal aspects of these events (e.g., Which animal went for a longer distance, or a longer time?). Results showed a reliable cross‐dimensional asymmetry. For the same stimuli, spatial information influenced temporal judgments more than temporal information influenced spatial judgments. This pattern was robust to variations in the age of the participants and the type of linguistic framing used to elicit responses. This finding demonstrates a continuity between space‐time representations in children and adults, and informs theories of analog magnitude representation.     

THE VARIETY OF PANENTHEISMS

Abstract. In this article I review the efforts of eighteen scientists and theologians, recorded in this book, to describe the relation of God to the universe during a conference sponsored by the John Templeton Foundation at Windsor Castle in 2001. Theologians from several branches of Christian faith articulate their understanding of panentheism, revealing a considerable diversity. I deal with each author in relation to six issues: the way God acts, how God's intimate relation to the world is to be described, the relation of God to spacetime, whether God is dependent upon the world, what type of language is used, and the problem of dipolar panentheism. I identify significant differences between these authors, suggest where fruitful dialogue is possible, and distinguish between intelligibility and plausibility in comparing dipolar panentheism with other types.

The development of conceptual interests in young children

We conducted a longitudinal analysis of the relative intensity and duration of interests associated with conceptual domains between the ages of 4 and 6 years, respectively. Results indicated a significant portion of preschool children do sustain an interest in conceptual domains during some portion of their childhood. Expected gender differences were found, with boys more likely to express an interest in a conceptual domain than girls. A latent growth curve analysis revealed that the probability of exhibiting a conceptual interest declined as school began, though the rate of that decline was similar for both boys and girls. Potential explanations for the decrease in conceptual interests as school begins are considered.     

Having Fun with the Periodic Table: A Counterexample to Rea’s Definition of Pornography

In a paper from 2001, Michael C. Rea considers the question of what pornography is. First, he examines a number of existing definitions of ‘pornography’ and after having rejected them all, he goes on to present his own preferred definition. In this short paper, I suggest a counterexample to Rea’s definition. In particular, I suggest that there is something that, on the one hand, is pornography according to Rea’s definition, but, on the other hand, is not something that we would intuitively describe as being an instance of pornography.

不同类型的知觉刺激对语言理解的影响

采用知觉负载范式探讨知觉刺激对语言理解的影响。实验1考察被试在加工听觉概念和视觉概念时的表征形式。实验2进一步探讨在同一通道内部,形状概念和视觉概念的表征形式。实验1发现,在进行语言理解时,如果存在听知觉负荷,加工语言中的听觉信息时会变慢。如果存在视知觉负荷,加工语言中的视觉信息时错误率会增加。实验2发现,在涉及视觉信息的语言理解中,颜色知觉负荷产生了广泛的影响,而形状知觉负荷没有表现出这种效应。总的实验结果表明,不同类型的知觉刺激对语言理解产生了不同的影响。语言理解中存在着模态化和非模态化两种不同的加工模式。     

Preschool children's use of cues to generic meaning

Sentences that refer to categories - generic sentences (e.g., "Dogs are friendly") - are frequent in speech addressed to young children and constitute an important means of knowledge transmission. However, detecting generic meaning may be challenging for young children, since it requires attention to a multitude of morphosyntactic, semantic, and pragmatic cues. The first three experiments tested whether 3- and 4-year-olds use (a) the immediate linguistic context, (b) their previous knowledge, and (c) the social context to determine whether an utterance with ambiguous scope (e.g., "They are afraid of mice", spoken while pointing to 2 birds) is generic. Four-year-olds were able to take advantage of all the cues provided, but 3-year-olds were sensitive only to the first two. In Experiment 4, we tested the relative strength of linguistic-context cues and previous-knowledge cues by putting them in conflict; in this task, 4-year-olds, but not 3-year-olds, preferred to base their interpretations on the explicit noun phrase cues from the linguistic context. These studies indicate that, from early on, children can use contextual and semantic information to construe sentences as generic, thus taking advantage of the category knowledge conveyed in these sentences.     

Facet-like Structures in Computer Science

This paper discusses how facet-like structures occur as a commonplace feature in a variety of computer science disciplines as a means for structuring class hierarchies. The paper then focuses on a mathematical model for facets (and class hierarchies in general), called formal concept analysis, and discusses graphical representations of faceted systems based on this model.
