闪光滞后效应的机制：时间错觉与空间错觉

闪光滞后效应（flash—lag effect,FLE）是指在与某运动物体相同的位置上呈现的闪光（flash）知觉上滞后于该运动物体的视错觉。本文简要介绍了有关闪光滞后效应机制的理论模型。笔者认为,目前各种理论的争议可归结为时间错觉假说与空间错觉假说之争,并在此基础上就今后进一步研究的方向提出了建议。     

Polger on the Illusion of Contingent Identity

Abstract

Thomas Polger has argued in favour of the mind–brain type‐identity theory, the view that mental states or processes are type‐identical to states of the central nervous system. Acknowledging that the type‐materialist must respond to Kripke’s modal anti‐materialist argument, Polger insists that Kripke’s argument rests on dubious assumptions concerning the identity conditions of brain states. In brief, Polger claims that one knows that x and y are non‐identical when one knows the identity conditions for both x and y. Replace x and y with ‘brain states’ and ‘sensations’ and it follows that one can know that brain states and sensations are non‐identical only if one knows the identity conditions for brain states. But according to Polger, we do not know the identity conditions for brain states. Hence, we should not be so confident that brain states and sensations are non‐identical after all. But Polger’s account is terribly flawed. Ironically, if Polger’s scepticism is warranted, then Polger himself has no good reasons to be a type‐materialist. But more importantly, Polger’s scepticism regarding the identity conditions of brain states is deeply defective. We do, I submit, understand the identity conditions of brain states. In the end, I submit, Kripke is safe from Polger.     

特殊的视错觉：运动诱导视盲

突显的静止目标被一定空间范围内运动背景所覆盖时, 人类会感受到静止目标消失再重现的发生, 这种视错觉现象叫做运动诱导视盲(motion-induced blindness, MIB)。该现象成因的理论解释主要有：注意竞争理论、知觉完型加工理论以及神经生理机制相关理论。作为特殊的视错觉现象, 该现象与其他盲视现象不同,主要是由客体识别过程中的知觉变化引起; 另一方面, 运动诱导视盲中“反知觉”现象的特殊性也是研究者关注的问题之一。神经生理机制层面的研究关注早期、晚期皮层在该现象发生时的变化, 采用眼动、脑电等技术对错觉现象发生时程进行测量与评估。文章在总结已有相关研究的基础上进一步指出今后可深入探索的研究方向有：MIB发生的深层机制、作为研究意识神经相关、无意识知觉加工等课题的工具、MIB中的意义性加工与认知冲突等。     

跨通道信源检测错觉的实验研究

本研究探讨跨通道信源检测错觉的特点。实验中将简单、无关且易产生视觉和听觉想像的事件随机以看、听、想像看和想像听的一种或两种组合方式让被试感受 ,2天后以视检测、听检测和全检测三种方式判断信源 ,结果均发现跨通道信源检测错觉 ,且信源判断受检测方式影响 ,知觉信息在源检测中具有更大的抗干扰性。研究结果支持信源检测理论。本文最后讨论了信源检测错觉的机制     

因果错觉的实验研究

本研究分别从可控情境和不可控情境两方面探讨了在工具性条件反射中,人对因果关系的认知的特点。结果发现：1．在可控情境下。延迟反馈可能导致被试的因果错觉;2、在不可控情境下,被试同样表现出因果错觉：迷信和控制幻觉,并且这种现象具有一定的普遍性;3、提供恰当的外部线索能有效地帮助被试消除已经形成的因果错觉。     

Contingency Horizon: on Private Events and the Analysis of Behavior

Skinner’s radical behaviorism incorporates private events as biologically based phenomena that may play a functional role with respect to other (overt) behavioral phenomena. Skinner proposed four types of contingencies, here collectively termed the contingency horizon, which enable certain functional relations between private events and verbal behavior. The adequacy and necessity of this position has met renewed challenges from Rachlin’s teleological behaviorism and Baum’s molar behaviorism, both of which argue that all “mental” phenomena and terminology may be explained by overt behavior and environment–behavior contingencies extended in time. A number of lines of evidence are presented in making a case for the functional characteristics of private events, including published research from behavior analysis and general experimental psychology, as well as verbal behavior from a participant in the debate. An integrated perspective is offered that involves a multiscaled analysis of interacting public behaviors and private events.

A New Tactile Illusion: Temporal Limits on the Processing of Spatiotemporal Patterns

A novel illusion was observed when 12 tactile point-stimulators arranged in a circle were sequentially activated so that each quadrant was first traced in a clockwise manner, then counterclockwise, and again in a clockwise manner, after which the next quadrant was similarly traced. Under certain temporal conditions this stimulus pattern was experienced as a point moving through an overall circular path but looping inwardly about once per quadrant. The effects of variations in rate of presentation of such stimuli were investigated by having subjects make drawings of their perceptual experiences. Three skin surfaces were used (palm, fingers, and forearm), and all produced similar results except for lower confidence and reliability of drawings made from forearm stimulation. Pattern presentation rate, however, had a consistent and powerful effect, with the looping illusion most frequently observed at rates around 25 pattern points per s and with different perceptual organizations dominating as rates departed widely from this optimum. The illusory perceptual organizations were interpreted as compromises between past and present stimulation necessitated by the relative slowness of tactile processing of spatio-temporal patterns.     

自我表征的可塑性:基于橡胶手错觉的研究

自我识别是人类自我觉知的行为标记。传统方法认为稳定的自我表征是自我识别的基础。随着对橡胶手错觉及一系列自我表征和自我识别错觉的揭示,这一能让人将外部客体感知为自身一部分的错觉研究使得我们能够以多感官整合的方式来研究自我表征和自我识别。拥有感和自主感被认为是我们进行自我识别的两类基本体验,本文对一系列橡胶手错觉范式研究的系统回顾表明,拥有感和自主感会发生改变,这说明人的自我表征是可变的和可塑的。

Counselors are often confronted with client goals that seem to be, at varying levels of awareness, elusive to either the counselor or the client.     

消费活动中品牌错觉产生和错觉类型的年龄特征的试验研究

Analytical Buddhism: The Two-Tiered Illusion of Self

In the contemporary debate on the nature of autonomy, it is generally taken for granted that autonomy is to be understood as rule by the self, with the debate centring on how that self is to be identified. Garnett [2013b Garnett, Michael 2013b. The Autonomous Life: A Pure Social View, Australasian Journal of Philosophy 91/4. [Google Scholar]] has recently proposed a theory that rejects the dominant understanding of autonomy as rule by the self and views it instead as resistance to rule by others. According to that theory, an autonomous agent is one whose various ‘autonomy traits’ render her sufficiently resistant to subjection to foreign wills. I argue that Garnett has not given us good reason to abandon the understanding of autonomy as rule by the self. His account is plausible only if it is understood to require for autonomy the possession of at least one trait with which the agent can be identified. And the best explanation of the necessity of some such trait(s) is offered, not by Garnett's, but by the dominant understanding of autonomy he rejects.     

Freud's Illusion: New Approaches to Intractable Issues

In his later theological work The Future of an Illusion, Freud (1927/1961) makes provocative suggestions about the psychological significance of religious ideas. Freud begins by analyzing their meaning in the lives of particular individuals. He then extrapolates to a critique of their effect on human civilization. Religion originally evolved in order to explain difficult concepts such as death and fate. It quickly outgrew its purely theological dimensions and became a social regulator by coercing compliance with a set of cultural norms.

The purpose of this article is not to evaluate whether Freud was right, that is, if religion in fact is an illusion. Rather, using concepts derived from current work in analytical theology, it examines the internal logic of Freud's analysis and some of the assumptions he made to reach this conclusion. Despite his theoretical insights, much of Freud's reasoning is invalid and many of his premises are questionable. Freud adopts assertions without explaining them and does not offer much in the way of deductive or inferential support for his argument. This article advocates an epistemological approach to understanding Freud's use of terms such as “wishes” and “illusions.” Adopting this perspective uncovers tacit presuppositions underlying his theory about the origins of religious belief and its relationship to culture and society, and clarifies the conceptual links holding it together.
