封闭性知觉在大范围优先性中的特殊性

本文研究当封闭性作为被试分辨的图形性质时,空间位置不确定性和视野位置对大范围优先性有何影响。实验发现：（１）无论复合刺激呈现在视野的中央或外周．分辨复合刺激的整体性质的反应时（ＲＴ）比分辨局部性质的ＲＴ短,整体性质对分辨局部性质的反应有较强的干扰作用。相反,局部性质对分辨整体性质的反应的影响较小;（２）刺激位置的不确定对大范围优先性没有显著影响;（３）与周边刺激相比,分辨视野中央的复合刺激的ＲＴ较短,但整体性质的ＲＴ优势和对局部性质的干扰作用,不受刺激在视野中的位置的影响。这些实验结果揭示了封闭性知觉在大范围优先性中的特殊性。     

Interpolation and Amalgamation; Pushing the Limits. Part I

Continuing work initiated by Jónsson, Daigneault, Pigozzi and others; Maksimova proved that a normal modal logic (with a single unary modality) has the Craig interpolation property iff the corresponding class of algebras has the superamalgamation property (cf. [Mak 91], [Mak 79]). The aim of this paper is to extend the latter result to a large class of logics. We will prove that the characterization can be extended to all algebraizable logics containing Boolean fragment and having a certain kind of local deduction property. We also extend this characterization of the interpolation property to arbitrary logics under the condition that their algebraic counterparts are discriminator varieties. We also extend Maksimova's result to normal multi-modal logics with arbitrarily many, not necessarily unary modalities, and to not necessarily normal multi-modal logics with modalities of ranks smaller than 2, too.The problem of extending the above characterization result to no n-normal non-unary modal logics remains open.Related issues of universal algebra and of algebraic logic are discussed, too. In particular we investigate the possibility of extending the characterization of interpolability to arbitrary algebraizable logics.     

Should a Naturalist Be a Supervenient Physicalist?

I clarify a widely accepted form of contemporary naturalism and argue that supervenient physicalism should not be considered an option for those who embrace this version of naturalism. Among other things, my thesis implies that if there are insuperable difficulties for strict physicalism, then the move toward supervenience views of the mind/body problem amounts to an abandonment of this version of naturalism and not a minor adjustment of it. More precisely, my argument is this: strict physicalism excludes both substance and property or event dualism. But the supervenience thesis entails some form of property or event dualism. So strict physicalism excludes the supervenience thesis. Moreover, given the nature of a widely accepted contemporary understanding of naturalism, it is best construed along strict physicalist lines and naturalists of this persuasion should not be supervenient physicalists. To make my case, I offer a characterization of a ubiquitous version of contemporary naturalism followed by an analysis of the most plausible version of supervenient physicalism consistent with this form of naturalism. I then try to show why this version of supervenient physicalism should not be an option for a naturalist of a certain persuasion.     

注意对拓扑性质和局部几何性质检测的不同影响──进一步的实验证据

实验研究了中央和外周提示信号对辨别朝向的任务（局部几何性质检测）和辨别有或无的任务（拓扑性质检测）的影响。结果表明,对于两种提示信号,在提示有效和提示无效条件下,辨别有或无比辨别朝向具有较短的反应时和较低的错误报告率;辨别朝向的ＲＴ和错误报告率都受提示信号的影响;而对于辨别有或无的任务,只有ＲＴ受提示信号的影响;提示信号对辨别朝向的影响比辨别有或无的影响大。本实验排除了对Ｈａｎ和Ｃｈｅｎ的实验的可能的光通量解释,并为提示信号对不同几何性质检测的不同影响提供了进一步的实验证据。     

No Harm,Still Foul: Concerns About Reputation Drive Dislike of Harmless Plagiarizers

Across a variety of situations, people strongly condemn plagiarizers who steal credit for ideas, even when the theft in question does not appear to harm anyone. Why would people react negatively to relatively harmless acts of plagiarism? In six experiments, we predict and find that these negative reactions are driven by people's aversion toward agents who attempt to falsely improve their reputations. In Studies 1–3, participants condemn plagiarism cases that they agree are harmless (i.e., stealing credit from an anonymous source). This effect is mediated by the extent to which participants perceive the plagiarizer to have falsely benefitted from plagiarizing. In Studies 4–5, we demonstrate that this effect is not explained solely by participants’ negative response to lies or violations of permission. In Study 6, participants condemn a plagiarism case in which the idea's original author actually benefits, providing the strongest evidence that people condemn plagiarism for reasons beyond perceived harm. We discuss how this work connects to broader questions of intellectual property and impression management.     

时间复制任务中的计时中断效应

以计时中断范式和时间复制任务相结合,考察了时间复制任务中是否存在计时中断效应。结果表明：（1）计时中断范式中1700ms和2300ms时距复制均出现高估现象,说明两种时距均低于相邻的高低估现象的转换点;（2）计时中断范式中1700ms和2300ms的时距复制任务没有支持计时标量特性;（3）计时中断范式中1700ms和2300ms的时间复制任务出现了计时中断效应。     

Aggression: Appetite or aversion?—An ethologist's viewpoint

The term “aggression” has been used to describe practically all situations in which an organism threatens, damages, or kills another-with the exception of certain predator-prey relationships. As a result, a great deal of confusion and controversy has arisen as to the causal factors and functions of aggression. The main ethological hypotheses concerning the nature of aggression are put forward. In order to illustrate the divergence in causal factors and functions, differences in motivational, physiological, and ecological bases of aggression in two closely related fish species are described. A basic division of aggression into “self-defensive” and “property-protective” behavior is suggested, together with the parameters separating these categories on behavioral, causal, and functional bases. Mechanisms which enable motivational changes from one category to another to take place during a single encounter are discussed, these being pain stimuli and physical or psychological “cornering.” The importance of learning effects on fighting behavior are emphasized, especially their negative and positive reinforcing effects in relation to self and property defense. The biological significance of aggressive conditioning for the animal and the role of aggression in species maintenance are discussed.     

PRIVATE PROPERTY AND ENVIRONMENTAL ETHICS:

Abstract: This article argues that teachers of environmental ethics must more aggressively entertain questions of private property in their work and in their teaching. To make this case, it first introduces the three primary positions on property: occupation arguments, labor theory of value arguments, and efficiency arguments. It then contextualizes these arguments in light of the contemporary U.S. wise‐use movement, in an attempt to make sense of the concerns that motivate wise‐use activists, and also to demonstrate how intrinsic value arguments miss the mark. Finally, it offers some suggestions about further directions for environmental ethics, reasoning that there is a good deal of headway to be gained for environmental ethics by accepting that nature can be owned as property, but nevertheless engaging the idea of private property critically.     

The Finite-Dimensional Freeman Thesis

I suggest a modification—and mathematization—of Freeman’s thesis on the relations among “perception”, “the finite brain”, and “the world”, based on my recent proposal that the theory of finite topological spaces is both an adequate and a natural mathematical foundation for human psychology.
