ALTERING RESPONSE CHAINS IN PATHOLOGICAL GAMBLERS USING A RESPONSE‐COST PROCEDURE

Two pathological gamblers could choose between emitting or having the dealer emit the response options when playing each of three casino games. A response‐cost procedure was introduced in a multiple baseline design across games in which the participant had to pay to perform the responses himself, which was somewhat effective at reducing many of the initial irrational choices made by each participant.     

The man who lost his body: Suboptimal multisensory integration yields body awareness problems after a right temporoparietal brain tumour

Reports on patients who lack ownership over their entire body are extremely rare. Here, we present patient SA who suffered from complete body disownership after a tumour resection in the right temporoparietal cortex. Neuropsychological assessment disclosed selective bilateral ownership problems, despite intact primary visual and somatosensory senses. SA's disownership seems to stem from a suboptimal multimodal integration, as shown by the rubber hand illusion and the beneficial effect during and after simple exercises aiming at multisensory recalibration.     

Mirrors and Misleading Appearances

Although philosophers have often insisted that specular perception is illusory or erroneous in nature, few have stressed the reliability and indispensability of mirrors as optical instruments. The main goal of this paper is to explain how mirrors can contribute to knowledge and at the same time be a source of systematic errors and misleading appearances. To resolve this apparent paradox, I argue that mirrors do not generate perceptual illusions or misperceptions, by defending a view of mirrors as transparent and invisible visual media. I then consider the reasons for which mirrors are said to be misleading. Contrary to the illusory account, I defend a nonperceptual approach to the errors attributable to mirrors, which analyses the kind of errors generated by the use of mirrors in terms of false judgments. I further show that a nonperceptual view of errors extends to all of the cases in which a sensorimotor adaptation is required, such as perception through magnifying or inversing lenses.     

积极错觉:基于进化论和社会互动的视角

积极错觉是积极心理学的一个重要研究领域,对于维持个体的身心健康至关重要。本文主要从进化论和社会互动论的视角对积极错觉进行阐述。从进化论的视角看,积极错觉有助于身心健康和认知适应; 从社会互动论视角看,积极错觉有助于维持良好的社会关系。未来的研究需要深化积极错觉的跨文化研究,重视对特殊群体积极错觉的研究,并加强积极错觉的应用研究和脑机制研究。     

赌博游戏中的near-miss效应

near-miss效应是指在赌博中, 与一般的输钱和赢钱相比, “几乎赢(near-miss)”的输钱会诱发个体更高的生理唤醒和更强的赌博动机, 从而导致个体持续赌博的一种现象, 是导致赌博成瘾的主要诱因之一。针对这种现象的研究范式大致有三种：老虎机/类老虎机任务、轮盘任务和刮刮乐彩票任务。这种现象的理论解释目前主要有认知曲解假说、控制幻觉理论和受挫假说。near-miss效应的脑机制和病理研究才刚刚起步, 所涉及到的脑功能区域主要包括脑岛、腹侧纹状体等。未来的研究应在near-miss效应发生机制的理论模型建构、研究范式多样化、研究技术多模态化、病理机制和临床干预等方面进一步展开。     

The effect of frame figure type and frame size on the line and the circle Ponzo illusions

Abstract:   To examine the determinants of the Ponzo illusion, we compared the perceived size of lines and circles presented within three different frames: two converging lines, two circles, and two squares. Twenty stimulus figures, consisting of two types of objects (lines/circles) × three types of frame figures (Ponzo/circles/squares) × three sizes of lower frames (small/medium/large), and two control figures were presented on a personal computer display. Twelve students performed three measurements (upper-object/lower-object/illusion) for each stimulus figure using the method of adjustment. To analyze the relationship between single object perception and the Ponzo illusion, we compared the calculated values of overestimation magnitude differences between the upper and lower objects with the actual obtained illusion values of the six object-frame conditions. The calculated values of the circle and the square frame figures corresponded to the difference between the upper single object and the lower single object. In contrast, the results of the Ponzo figure need an additional factor to explain the differences between the obtained and the calculated values. These results indicate that two factors are involved in the Ponzo illusion: (a) the framing effect affects the perceived size of the individual single objects, and (b) the comparison factor affects the comparison process of the two objects within the converging lines.     

内隐记忆研究的新进展:概念、实验和模型

本文回顾了近年来内隐记忆研究的新进展。内隐记忆概念的描述性和模糊性正受到研究者的批评。对此概念进行更准确地把握在当前愈显紧迫和必要。多数研究者仍继续沿用这一术语．最近的实验研究修改了部分早期结论．并开始与学习和记忆研究的其他领域,尤其是涉及无意识过程的领域互相结合。内隐记忆的解释和建模呈现出从定性到定量的发展趋势。     

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。     

Imagination and the imaginary

This paper argues that real imagination depends on the capacity to acknowledge the absence of what is imagined from the world of material actuality. This leads on to a view of symbol formation as the operation of the transcendent function between the opposites of presence and absence. 'The imaginary' is contrasted with this as a defensive misuse of imagination that attempts to deny 'negation' where negation is defined as all those aspects of the world that constitute a check to the omnipotence of fantasy--e.g., absence, loss, difference, otherness etc. Parallels are drawn with theoretical antecedents in analytical psychology and psychoanalysis, with particular attention to papers published in the Journal of Analytical Psychology (JAP) in the 1960s on the relation between active imagination, transference and ego development. A clinical example is given to show the use of the imaginary as a means of warding off the unbearable pain of Oedipal disappointment.     

Grace and Imagination: From Fear to Freedom

Creative use of our imagination is essential if we are to live a vibrant life. Although our use of imagination is often blocked by various fears, D. W. Winnicott's insights into play, aggression, and the use of transitional objects open up paths towards greater freedom. The sacred texts, symbols, and liturgies of our religious traditions can then become the toys which engage us in profound and re-creating soul play. Through grace and the evocative examples of our teachers, we can find ways to use our imagination more freely to deepen our spiritual life and psychological wholeness.
