Perception2

The article is an overview of some central philosophical problems associated with perception. It discusses what distinguishes perception from other sensory capacities and from conception. It discusses anti‐individualism, a view according to which the nature of a perceptual state is dependent not just causally but for its identity or ‘essence’ on relations to a normal environment in which systems containing that state were formed. It discusses different views about epistemic warrant. By emphasising the deep ways in which human and animal perceptual systems, especially visual systems, are similar, it criticises a dominant view of the last century, in both philosophy and large parts of psychology, according to which a range of sophisticated supplementary abilities have to be learned before a child can perceive objective features of the physical world.     

成人与中学生科学概念形成过程的四个对比实验

以一组非人工的、自然的科学概念(“反作用力”、“机械能守恒”、“熵”和“场”)为学习内容,分别以成人和中学生为被试,实验研究成人和中学生科学概念形成过程的异同。结论如下：(1)成人与中学生科学概念形成过程均分为振荡渐进期、高原期和突变期。(2)成人的振荡渐进期较长;中学生的振荡渐进期较短且振荡特征比较明显。(3)成人的高原期出现较晚,但持续较长;中学生的高原期出现较早,但持续较短。(4)中学生的突变期的跨度随概念的抽象程度提高而越来越大。     

足部畸形的矫正与美学要求

现在,对足部畸形的定义、外科矫正要求、技术方法的选择与治疗目标的确立出现了新的概念,即在保证医疗效果的前提下必须兼顾美学和患者心理的要求。这就要求现代的骨科医生应当学习、提高美学的相关知识,用艺术的视角、美学的方法和数字化的科学标准,评估技术方法、医疗流程和治疗结果,使每例足踝畸形的矫正达到满意的疗效和艺术作品的效果。     

The influence of extreme traumatization on body, mind and social relations

Extreme traumatization affects the individual's relation to others in several social and psychological ways. The post-traumatic experiences are characterized by helplessness, insecurity, anxiety, loss of basic trust, and fragmentation of perspectives on one's own life. Special considerations should be given to the destruction of the ability to regulate negative emotions (extreme fear, distress, anguish, anger, rage, shame) in relation to others and activate internal good and empathic object relations. Destruction of the capacity for symbolization of traumatic experience may threaten the mind with chaotic states against which the 'I' tries to defend itself and find a balanced psychic mise-en-scene. The authors emphasize three dimensions that the analyst should observe in his understanding of the traumatized mind and its conflicts. The proposed dimensions are called the body-other dimension, the subject-group dimension, and the subject-discourse dimension. All three dimensions have specific structural characteristics that are expressed in the analytic relation. Extreme trauma causes disturbances in each of these dimensions. The authors present clinical material from a traumatized refugee to illustrate the analytic work.     

The Button to Make Poverty History &; How to Double Your Donation

Even if together we could make poverty history, we would not all do our part. The paper presents a device that makes it more likely for everybody to do his part. This is achieved by making everybody’s contribution dependent on the other people’s commitment to contribute given that certain conditions are fulfilled. Furthermore, a device is introduced which, based on the same general idea, doubles everybody’s donation. Finally, possibilities, assumptions and limitations of such devices are addressed.     

父母-儿童共同活动中的互动与儿童的数学学习

本研究运用结构性观察方法对两组4岁儿童与父母在四种活动中的互动进行了分析与比较。一组儿童为书面数符号测查高分者,二组儿童为书面数符号测查低分者。85对父母一儿童对子参加了4个各有15分钟的共同活动,阅读、数学题、纸和积木,并完成一个微型问卷。结果表明,在这些活动中包含了多种数学知识学习和多种以父母为主导的互动策略;两组对子之间在数学事件频次上无差异,但一组父母更多地运用了一些积极策略,二组父母更多地运用了一些消极策略;二组中有更多儿童对互动表现出消极回应和注意力问题。两个组的父母在家中与儿童一起进行诸如阅读和做数学题的共同活动的频次与质量上表现出差异。

Identity matching-to-sample with olfactory stimuli in rats

Identity matching-to-sample has been difficult to demonstrate in rats, but most studies have used visual stimuli. There is evidence that rats can acquire complex forms of olfactory stimulus control, and the present study explored the possibility that identity matching might be facilitated in rats if olfactory stimuli were used. Four rats were trained on an identity match-to-sample procedure with odorants mixed in cups of sand as stimuli. Digging in the sample cup produced two comparison cups, and digging in the comparison cup that contained the same scent as the sample was reinforced. When criterion accuracy levels were reached, novel stimuli were added to the baseline training regimen. All 4 rats reached terminal performance of above 90% correct matching with more than 20 different baseline stimuli and matched novel stimulus combinations with above-chance accuracy; 3 of the 4 rats matched novel stimuli at levels significantly above chance. Accurate matching performance was demonstrated both with 2- and 3-comparison procedures. These results suggest that generalized matching-to-sample can be observed in rats when olfactory stimuli are used and, furthermore, that multiple-exemplar training may be important for its emergence.     

'Do be my enemy for friendship's sake' (Blake)

The author explores our psychological need for enemies and the contribution this makes to overt conflicts in the external world. Enemies serve as an opposite from which we can differentiate ourselves, either as an individual or as a group; they help us to define our physical and psychological boundaries. Enemies provide a target and an outlet for our aggression and also for the projection of the shadow. They also provide the stimulus to individuation, through the heroic encounter with the enemy in the unfamiliar world outside the home, particularly in adolescence. The psychic integration of 'self' and 'enemy' is explored as the outcome of individuation.
