安乐死对象的界定

目前关于安乐死对象的界定,突出了医学要件,忽略了权利要件。为安乐死立法,必须对安乐死对象作出法律界定,应该满足两个条件：一是自然条件,即存在死亡痛苦;二是权利条件,即公民享得并行使安乐死的权利。不规定和具备权利条件,仅存在死亡痛苦,在法律上不能列为安乐死对象。     

儿童对图画兴趣和表征发展差异的跨文化研究

本实验是一项跨文化的比较研究 ,旨在探索儿童对图画兴趣的动态变化及表征的发展。被试年龄跨度为 4岁至成人 ,均未受过美术训练。通过他们各自根据线条画中所含的颜色或主题或情绪的特性匹配的特点 ,来发现内在的规律。实验发现年幼儿童以颜色为匹配标准 ,年长儿童和成人则以主题或情绪为主。中国儿童比英国儿童对图画中的语义联系 (表达的情绪 )更敏感。在主题 /情绪匹配中 ,中国 1 0岁儿童和成人都侧重情绪特征 ,而英国儿童随年龄发展由主题特性转向情绪特性这一兴趣的发展趋势并不明显。本文从美学的角度应用当代有关图画表征发展的理论对实验进行了分析 ,探讨了在中英不同文化背景下影响儿童兴趣变化及表征能力发展的因素。     

Multi-Encoding for Pitch Information of Tone Sequences

This study was designed to investigate the possibilities that subjects would visualize an auditory contour as a visual contour (visual imagery) to encode pitch information of tone sequences (Experiment 1), and that subjects would be motivated to attempt to engage in covert rehearsal with multi-code (Experiment 2). The findings from these experiments suggest that: (a) Whereas the highly musically trained subjects were able to encode pitches as accurate notes on a staff, the less well musically trained subjects encoded the pitch sequence as a contour. It is quite evident that there is an intermodal analogy between the perception of pitch relationships and that of relationships in visual space. (b) Pitch rehearsal of auditory information along with note names (dual-code) and staff notation accompanied by pitch rehearsal with note names (triple-code) were the most effective strategies for highly trained subjects with pitches of tonal sequences; melodic contour accompanied by pitch rehearsal (dual-code) was used by highly trained subjects with atonal sequences and by less well trained subjects with both types of sequences.     

目标与非目标数量变化对多目标追踪的选择性抑制效应

采用多目标追踪和点探测刺激觉察任务相结合的实验范式,考察目标和非目标数量变化对多目标追踪的选择性抑制效应。实验一设置非目标恒定而变化目标数量,结果发现：随着目标数量的增加,目标与非目标间的抑制差异量不随目标数量变化而变化。实验二设置目标恒定而变化非目标数量,结果发现：在非目标数量变化的三种水平下,目标与非目标间的抑制差异量也无显著差异。综合实验结果表明：在多目标追踪的追踪容量或抑制容量范围内,抑制差异量对目标数量或非目标数量变化是不敏感的;注意资源分配方式在一定范围内保持相对稳定。     

同音字族内的听觉通道词频效应与同音字表征的激活

对于同音词家族较大的词汇(例如汉语单音节词), 听觉通道的词汇通达和词汇表征的激活会受同音词汇歧义怎样的影响, 仍不很清楚。本研究采用了两个听觉通道的实验。实验一的听写任务发现在孤立音节的同音字选择上存在歧义的同时还存在同音字族内的高频偏向, 并非随机选择; 实验二的音-字同音判断任务对比同音与不同音条件得到同音促进量, 揭示了孤立音节在激活语音表征时还会引起同音高频字表征的自动激活, 而同音低频字则受到抑制。结果说明存在同音字族内的听觉通道词频效应, 同音的高、中、低频字的表征激活具有不同等性, 导致不穷尽通达, 且同音的最高频字得到更多通达机会。这些发现难以被现有的词汇通达和同音词表征激活模型解释, 文章提出一个能够解释这些听觉通道发现的模型。     

Ape metaphysics: object individuation without language

Developmental research suggests that whereas very young infants individuate objects purely on spatiotemporal grounds, from (at latest) around 1 year of age children are capable of individuating objects according to the kind they belong to and the properties they instantiate. As the latter ability has been found to correlate with language, some have speculated whether it might be essentially language dependent and therefore uniquely human. Existing studies with non-human primates seem to speak against this hypothesis, but fail to present conclusive evidence due to methodological shortcomings. In the present experiments we set out to test non-linguistic object individuation in three great ape species with a refined manual search methodology. Experiment 1 tested for spatiotemporal object individuation: Subjects saw 1 or 2 objects simultaneously being placed inside a box in which they could reach, and then in both conditions only found 1 object. After retrieval of the 1 object, subjects reached again significantly more often when they had seen 2 than when they had seen 1 object. Experiment 2 tested for object individuation according to property/kind information only: Subjects saw 1 object being placed inside the box, and then either found that object (expected) or an object of a different kind (unexpected). Analogously to Experiment 1, after retrieval of the 1 object, subjects reached again significantly more often in the unexpected than in the expected condition. These results thus confirm previous findings suggesting that individuating objects according to their property/kind is neither uniquely human nor essentially language dependent. It remains to be seen, however, whether this kind of object individuation requires sortal concepts as human linguistic thinkers use them, or whether some simpler form of tracking properties is sufficient.     

Interpersonal similarity as a social distance dimension: Implications for perception of others’ actions

Building on the assumption that interpersonal similarity is a form of social distance, the current research examines the manner in which similarity influences the representation and judgment of others’ actions. On the basis of a construal level approach, we hypothesized that greater levels of similarity would increase the relative weight of subordinate and secondary features of information in judgments of others’ actions. The results of four experiments showed that compared to corresponding judgments of a dissimilar target, participants exposed to a similar target person identified that person’s actions in relatively more subordinate means-related rather than superordinate ends-related terms (Experiment 1), perceived his or her actions to be determined more by feasibility and less by desirability concerns (Experiment 3), and gave more weight to secondary aspects in judgments of the target’s decisions (Experiment 2) and performance (Experiment 4). Implications for the study of interpersonal similarity, as well as social distance in general, are discussed.     

“<Emphasis Type="Italic">Do the very best you can</Emphasis>”: The third-grade class test

The aim of this study was to examine third-graders’ test situations such as they appeared in the day-to-day functioning of the school. The research was ethnographic, focusing on the test situations of one third-grade class in the mother tongue and mathematics during one school year. Our analyses suggest that third-graders no longer see the test practices as objects of learning but rather as a familiar part of their everyday schoolwork. The test-taking practices have been mastered, but preparation for the test still needs to be emphasized and practised. And, according to our findings, cheating is an object of practice as well. To third-graders, test situations appear as ‘real tests’: the evaluative import of these situations seems clear to them. The teacher and the school institution reach for maximal proficiency and performance so as bring out the pupils’ ‘pure’ ability and performance in the class test. The class teacher must deal with the ever-strengthening evaluative significance of the test in relation to both the pupils and the school administration: we find that in the test situation the class teacher creates a social-psychological we-group—an alliance of the teacher and the pupils versus the test writer—as comes out particularly clearly in connection with national tests. The findings of the study are discussed with special reference to the ways in which the class test constructs the selective-restrictive sphere of education.     

Intersubjectivity in perception

The embodied, embedded, enactive, and extended approaches to cognition explicate many important details for a phenomenology of perception, and are consistent with some of the traditional phenomenological analyses. Theorists working in these areas, however, often fail to provide an account of how intersubjectivity might relate to perception. This paper suggests some ways in which intersubjectivity is important for an adequate account of perception.

Insight without cortex: lessons from the avian brain

Insight is a cognitive feature that is usually regarded as being generated by the neocortex and being present only in humans and possibly some closely related primates. In this essay we show that especially corvids display behavioral skills within the domains of object permanence, episodic memory, theory of mind, and tool use/causal reasoning that are insightful. These similarities between humans and corvids at the behavioral level are probably the result of a convergent evolution. Similarly, the telencephalic structures involved in higher cognitive functions in both species show a high degree of similarity, although the forebrain of birds has no cortex-like lamination. The neural substrate for insight-related cognitive functions in mammals and birds is thus not necessarily based on a laminated cortical structure but can be generated by differently organized forebrains. Hence, neither is insight restricted to mammals, as predicted from a “scala naturae”, nor is the laminated cortex a prerequisite for the highest cognitive functions.
