社会场景下联合表征的整合机制

人们在交互过程中会同时表征自我和他人相关的信息,形成社会性联合表征.然而,自我和他人相关信息是以整合还是分离的形式存在,这一问题尚未厘清.本研究以工作记忆蓬佐错觉为指标展开了探讨.实验中要求两名被试分别记忆部分构成蓬佐错觉的线段并回忆.结果发现,竞争和合作场景下的个体不仅表征了他人相关的信息,还将其和自身相关的信息进行了整合,形成工作记忆蓬佐错觉效应,表明社会交互条件下会自动整合成社会性共同表征.     

The destruction of time in pathological narcissism

This paper describes the characteristics of subjective time (in contrast to objective time), with particular reference to a specific form of pathological experience and relation to the passage of time in patients with narcissistic personality undergoing psychoanalytic treatment. The clinical manifestations and technical approach to this pathology of time experience are outlined in the context of illustrative clinical vignettes.     

热手谬误和赌徒谬误心理机制研究述评

在知觉随机序列时,人们倾向于把序列中实际上各自独立的相邻结果看作是存在正相关或负相关的,而出现热手谬误或赌徒谬误,又称为随机序列中的正负近因效应。有关这两谬误最早的心理机制的探索中,Kahneman 和Tversky采用局部代表性启发法对此进行了解释。但是这种解释也存在诸多不足,因此近期的一些模型（因果模型、Urn模型、记忆模型、适应模型和两阶段格式塔模型）分别从不同角度对两种谬误提出了新的解释。最后文章指出研究方法、神经机制、个体差异以及生活中的应用是该领域研究的几个未来发展方向     

Is there an ‘end of history illusion’ for life satisfaction? Evidence from a three-wave longitudinal study

According to the ‘end of history illusion’ (EOHI) individuals underestimate the amount of future change they will experience. Using results from a three-wave longitudinal study of American adults (N = 2390, mean age = 55.31 years, 56% female), we examined ratings of recollected past (10 years prior), current, and anticipated future (10 years later) life satisfaction at Wave 2, as well as current life satisfaction at Wave 1 (nine years earlier) and at Wave 3 (nine years later). Younger adults typically underestimated their past and overestimate their future LS, whereas older adults tended to underestimate their future LS. Contrary to the EOHI, most individuals either were accurate or anticipated too much change into the future, rather than too little.     

2009年贵阳市住院儿童手足口病病原学及临床特点

为了解贵阳地区2009年4月~9月儿童手足口病的病原学及临床特点。从住院的820例手足口病患儿中采集部分伴有重症倾向的244例患儿的肛试子和咽试子标本进行RT-PCR技术检测,并进行临床观察。218例检测到肠道病毒,占89.34%,其中138例为EV71,占63.30%。72例为CA16,占33.02%,两者之比1.92:1。不同年龄组的病原构成差异有统计学意义(P0.01)。重症病例EV71感染明显高于轻症病例,两者在临床特征方面差异有统计学意义(P0.01)。2009年贵阳市住院儿童手足口病的主要病原是EV71和CA16;1岁~3岁的患儿EV71感染明显高于CA16,EV71比CA16更易引重症手足口病,重症病例与轻症病例在临床表现上有明显差异。     

AN ANALYSIS OF THE REINFORCING PROPERTIES OF HAND MOUTHING

Hand mouthing often has been described as a stereotypic response that is maintained by non-social (automatic) reinforcement; however, data supporting this conclusion can be found in relatively few studies. This series of studies presents an experimental analysis of conditions associated with the maintenance of hand mouthing. In Experiment 1, a functional analysis was conducted for 12 individuals who engaged in chronic hand mouthing to determine whether the behavior is usually maintained independent of social contingencies. Results obtained for 10 subjects were consistent with an automatic reinforcement hypothesis; the remaining 2 subjects' hand mouthing was maintained by social-positive reinforcement. Based on these results, Experiment 2 was designed to identify the specific reinforcing properties of hand mouthing. Each of 4 subjects was provided with a toy that substituted for hand mouthing, and preference for a specific topography of toy manipulation (hand-toy contact or mouth-toy contact) was measured. Results indicated that hand stimulation was the predominant reinforcer for all subjects. Experiment 3 provided an extension of Experiment 2 in that the same responses were measured across a variety of toys presented to each of 5 subjects. Results again indicated that hand stimulation was the predominant reinforcer for all subjects. Implications of these results are discussed with relevance to treatment.     

TWO MEASURES OF PREFERENCE DURING FORCED-CHOICE ASSESSMENTS

A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli during forced-choice assessments.     

‘Eppur si move’: The Association Between Electrophysiological and Psychophysical Signatures of Perceived Movement Illusions

Vibration applied to muscle tendons induces an illusory perception of movement by activating spindle receptors and Ia afferent fibers. While neural structures supporting such illusions are quite defined, functional and psychophysical correlates of their perception have not been deeply investigated. The authors aimed at exploring subjective perception of illusory movements thanks to a repeated-stimulation multimodal approach. The integrated analysis of electroencephalography, source data (standardized low-resolution brain electromagnetic tomography–sLORETA), and psychophysical evaluation pointed at the activation of a frontoparietal sensorimotor network, with prefrontal-medial regions mainly involved in supporting the awareness for illusory movements. Further, illusions showed consistency in terms of presence, vividness, and duration. Finally, superior parietal structures seemed to play an important role in self-attribution of agency and ownership during such experiences.     

Evolutionary possibilities: Can a society be constrained so that “the good” self-organizes?

Can a human society be constrained in such a way that self-organization will thereafter tend to produce outcomes that advance the goals of the society? Such a society would be self-organizing in the sense that individuals who pursue only their own interests would none-the-less act in the interests of the society as a whole, irrespective of any intention to do so. The paper sketches an agent-based model that identifies the conditions that must be met if such a self-organizing society is to emerge. The model draws heavily on an understanding of how self-organizing societies have emerged repeatedly during the evolution of life on Earth. The model demonstrates that the key enabling requirement for a self-organizing society is ‘consequence-capture’. Broadly this means that all agents in the society must capture sufficient of the beneficial (and harmful) consequences of their actions for the goals of the society. ‘Consequence-capture’ can be organized in a society by appropriate management (systems of evolvable constraints) that suppresses free riders and supports pro-social actions. In human societies these constraints include institutions such as systems of governance and social norms. If a self-organizing society is to emerge, consequence-capture must apply to all agents in the society, including those involved in the establishment and adaptation of institutions. If this is achieved, the result will be a fully self-organizing society in which the interests of all agents (including individuals, firms, multi-national corporations, political organizations, institutions and governments) are aligned with the interests of the society as a whole.     

The second me: Seeing the real body during humanoid robot embodiment produces an illusion of bi-location

Whole-body embodiment studies have shown that synchronized multi-sensory cues can trick a healthy human mind to perceive self-location outside the bodily borders, producing an illusion that resembles an out-of-body experience (OBE). But can a healthy mind also perceive the sense of self in more than one body at the same time? To answer this question, we created a novel artificial reduplication of one’s body using a humanoid robot embodiment system. We first enabled individuals to embody the humanoid robot by providing them with audio-visual feedback and control of the robot head movements and walk, and then explored the self-location and self-identification perceived by them when they observed themselves through the embodied robot. Our results reveal that, when individuals are exposed to the humanoid body reduplication, they experience an illusion that strongly resembles heautoscopy, suggesting that a healthy human mind is able to bi-locate in two different bodies simultaneously.
