THE HORIZONTAL-VERTICAL ILLUSION AND THE ECOLOGICAL HYPOTHESIS

L'illusion de la verticale et L'hypothèse écologique. — La discussion dont L'hypothèse écologique a été récemment L'objet, paraît ignorer, en ce qui concerne L'illusion verticale, un article de Künnapas (1955) qui démontre que cette illusion se compose de deux effets: 1) L'un qui est attribuable à la verticalité de la ligne; 2) L'autre qui est dû à L'intersection d'une ligne par L'autre. L'A. a réalisé une expérience qui, avec des stimuli différents, a donné des résultats qui sent en accord avec ceux de Künnapas. Une critique de la littérature consacrée à ce problème suggère que les données se raccordent mieux à L'hypothèse, bien qu'encoie imparfaitement, si L'on tient compte de la dualité des effets. L'auteur souligne la complexité du problème et pense que la symétrie pourrait être considérée comme un facteur additionnel.     

关于早期知觉过程中注意资源分配权重的实验研究

本研究将早期知觉过程中分配的资源比例理解为权重。实验采用中心提示法,探讨了字母、数字、图形和颜色四种刺激特征的早期识别过程中资源分配权重问题。结果发现：（１）颜色不易受到提示的影响,而其它三个特征则受提示的影响较大;（２）在弱提示位置上,对数字的识别比对字母和图形的识别要难,而在强提示位置上,则相差不大。说明这四种刺激特征的注意权重在知觉加工的初始阶段是不同的;这种“不同”是早期知觉过程中刺激因素与注意资源分配之间相互作用的结果。     

THE MOVING RADII ILLUSION

When a set of concentric circles is subjected to a rinsing motion, moving radii will be seen. The phenomenon is explained in terms of the dependency of the intensity of the receptor processes on the time of stimulation. It is suggested that the term effect be substituted for the term illusion in describing the phenomenon.     

FOUNDATIONALLY JUSTIFIED PERCEPTUAL BELIEFS AND THE PROBLEM OF THE SPECKLED HEN

Many epistemologists accept some version of the following foundationalist epistemic principle: if one has an experience as if p then one has prima facie justification that p. I argue that this principle faces a challenge that it inherits from classical foundationalism: the problem of the speckled hen. The crux of the problem is that some properties are presented in experience at a level of determinacy that outstrips our recognitional capacities. I argue for an amendment to the principle that adds to its antecedent the requirement that the subject have a recognitional capacity with respect to the given property.     

THE STABILITY OF PATHOLOGIC SIGNS IN THE PERCEPTUAL PROCESS AS REVEALED BY A SERIAL TACHISTOSCOPIC EXPERIMENT

S mith , G. J. W., and J ohnson , G. The stability of pathologic signs in the perceptual process as revealed by a serial tachistoscopic experiment. Scand. J. Psychol ., 1961, 2, 142–148.—The study demonstrates high inter-rater and inter-set consistency in a serial tachistoscopic experiment utilizing pairwise presentations of stimuli A and B, B being presented at constant time levels, A at gradually increasing ones. Two parallel sets contain two series each. In one series A is incongruent with B, in another a threat directed against B. Fifty psychiatric patients are given the two sets with a one-day interval. Reports of change in A and B during the micro-genesis of A are scored in the dimensions of repression, isolation, projection, and depression.     

关联性记忆错觉的产生与保持

两项实验对关联性记忆错觉的产生与保持进行了考察。实验结果表明,关联性记忆错觉接近学过词的回忆水平,但它的产生不随年龄的变化而变化;时间变量对关联性记忆错觉的影响不显著。此外,关联性记忆错觉不同于学过的词,在延迟加快时没有系列位置效应的产生。     

感知负载对干扰效应和负启动效应的影响

保持刺激图形恒定,用改变任务难度的方法操纵负载的高低,研究了负载的变化对干扰效应及负启动效应的影响。实验结果显示在零负载时出现干扰效应,而高、低负载时干扰效应消失;同时在低、零负载时出现负启动效应,在高负载时负启动反转为正启动。这些结果说明负载的变化对干扰子的状态有明显的作用,但正启动效应的出现显示高负载并不能完全排除对干扰子的加工。     

THE ILLUSION OF SYSTEMATIC DISTORTION

This reply to Sypher argues that neither his data nor his analysis provide good evidence for confirming the systematic distortion hypothesis in general or showing that it is operative in the communicator style measure in particular. At best, Sypher's research provides additional construct validity for the communicator style domain. It is maintained that “difficult memory conditions” do not prevail for the self-report of style behaviors. Three studies are briefly reported supporting this conclusion. Finally, necessary conditions are identified in order for self-report data to be increasingly useful. Although the results of factor analyses (and related methods) of sets of ratings are often of immediate and intrinsic interest, there are few personality psychologists today who would claim that obtained factor structures represent inexorable verities (cf. Lykenn, 1971). It is now well recognized that by varying the mix of variables included in a clustering analysis, one can fundamentally alter both the number and nature of the summarizing dimensions subsequently obtained.     

PERSONALITY AND PERCEPTUAL EXPERTISE:

Abstract— We hypothesized that people become expert at perceiving information that is related to concepts they think about a great deal, because of their extensive perceptual experience with this material To test this idea, we manipulated the capitalization of a series of briefly exposed words If expertise emerges because of perceptual experience, then people should show facilitation identifying words that they think about a great deal, but only when capitalization of these words is consistent with prior perceptual experience with these words Support for this hypothesis was found in two experiments–one in which trait words were presented to depressed and nondepressed subjects, and one in which food words were presented to anorexic and nonanorexic subjects Thus, these experiments demonstrated that personality, as well as personality disorder, has the potential to change the nature of the input people receive from the perceptual system     

THE MAIN PART AND PILLAR OF BERKELEY'S THEORY: IDEALISM AND PERCEPTUAL HETEROGENEITY

Berkeley subscribed to the principle of heterogeneity, that what we see is qualitatively and numerically different from what we touch. He says of this principle that it is “the main part and pillar of [his] theory.” The argument I present here is that the theory to which Berkeley refers is not just his theory of vision, but what that theory was the preparation for, which is nothing less than his idealism. The argument turns on the passivity of perception, which is what is at stake in the principle of heterogeneity. The author targeted by Berkeley's theory is Descartes, who explicitly denies heterogeneity.     

发展性阅读障碍与知觉加工

近年来许多行为实验和神经生理学实验都发现 ,发展性阅读障碍与基本知觉障碍有关。在视觉领域研究者提出了巨细胞障碍假设 ,这种假设认为阅读障碍者视觉神经系统中的巨细胞障碍导致他们对某种类型的视觉刺激加工存在困难 ,进而影响阅读。在听觉领域研究发现阅读障碍者加工快速、系列、短暂呈现的声音刺激存在障碍。研究者认为阅读障碍者加工快速刺激输入障碍反映了普遍的时间知觉障碍。这方面的研究发展非常迅速 ,理论观点非常明确 ,并且直接与内在的神经机制相联系 ,形成了与传统的“语言障碍”理论迥然不同的“知觉障碍”理论。“知觉障碍”理论综合了行为、认知和神经等多个层次的研究 ,反映了神经科学发展所带来的巨大影响和认知加工模块化理论的渐渐衰退。     

SENSATION SCALES IN THE SIZE-WEIGHT ILLUSION

S joberg , L. Sensation scales in the size-weight illusion. Scand. J. Psychol ., 1969, 10 , 109–112.-The subjects gave magnitude estimations of heaviness of a set of cylinders varying simultaneously in weight and height. The size-weight illusion could be well described by a simple model assuming heaviness to be inversely proportional to a sensation scale of size and directly proportional to a sensation scale of weight. The scale parameters corresponding to weight were a positively accelerated function of weight while the corresponding function for size was negatively accelerated.     

知觉与行为分离现象在二维铁钦纳错觉实验中的验

利用二维铁钦纳错觉图片对单手及双手抓握情境下的知觉与行为分离现象进行实验验证,并探讨注意引导等因素对分离现象的影响。实验包括知觉任务和行为任务两项内容,前者主要测量被试的主观错觉量,后者则探讨分离现象是否存在及其影响因素。在行为任务中,记录被试在中心（目标）圆尺寸“实际相同”和“知觉相同”等不同情境下的行为,以拇指和食指抓握图片中心圆的最大抓握孔径为行为指标。结果发现：单手抓握时,左、右手的行为虽然在一定程度上受到了错觉的影响,但均显示出分离现象;双手抓握时,右手受错觉影响的程度减少,分离现象增强,而左手的结果则比较混淆。因此,分离现象是存在的,但它的出现可能受到注意引导、注意分配倾向或双手协调能力等因素的影响。     

正常成人的形重錯觉

問題 一斤鉄同一斤棉花的物理重量是相等的,但是,两者在輕重之感上是不一样的。輕重之感主要取决于物体的重量,但是这并不是一个簡单的比例关系。人們比較(不是衡量!)一斤棉花与一斤鉄的輕重时,都会感觉到后者較前者重得多。輕重之感往往靠提举物体
