重建权利和义务的平衡

以往我们过多地强调权利而忽视义务的教育使一些人错误地认为人们只有权利而不必尽义务。第二次世界大战后第二代人的一个代言人曾经提出一种新的、来自责任方面的自由,这种自由是指,人     

科学的统一

1.分类与系统论自有了科学以来,自有了欧洲哲学以来,人们就梦想着科学的统一,梦想着能有一个统一的科学体系。即使在科学哲学创立之前,希腊人的思想就发展到了这一步,即认为甚至科学和哲学也能构成一种哲学的统一。这种观点的影响早已烟消云散了。今天,在这种观点一度占支配地位的那些领域中,我们不断发现了一些未曾阐述清楚的经验关系和系统关系。我们不再讨论科学(与或不与哲学)的统一,而是讨论学科性、多学科性和学科间性,抚昔追今,我们所探讨的知识秩序已不再能用知识本     

青少年自我肯定性的发展及转换的印象知觉对其影响的研究

本文以问卷法考察初二、高二和大二学生自我肯定性的发展及转换的印象知觉对其的影响。结果发现:1)被试自我肯定性的发展随年龄增长经历了“较肯定——较不肯定——较肯定”的过程且无性别差异。2)高估自己的人比低估者更倾向于自我肯定。3)主观上他人对己的看法比客观上他人对已的看法对己影响更大.主观上认为他人对己看法的分歧性越大,对自己越肯定。     

Role of eye and hand initial position in the directional coding of reaching

To investigate the nature of the frames of reference used to control an arm movement aimed at a visual target, we studied the accuracy of movements differing by the initial arm and eye positions. The results support the assumption that in darkness target location is internally represented in an egocentric frame of reference. Furthermore, when movements carried out with and without eye saccade are compared, it appears that foveating the target changes the reference used to generate the reaching arm movements, that is, the oculocentric reference is replaced by a head-trunk reference. An explanation for this phenomenon could be that a steady body-related landmark is needed to insure stable registering of the target location in the surrounding space, despite displacement of the body segments with respect to one another.     

Harming future people

Hanser examines Derek Parfit's contention in his treatise on rationalism, Reasons and Persons (Oxford University Press; 1984) that acts that are not reproductive in nature can nonetheless predictably affect the identities of future people, and that this fact has unexpected and important consequences for ethical theory. Hanser argues tht this fact is not as significant as Parfit believes it to be. The arguments of both scholars concern the morality of choices that, while causing future persons to be badly off, do not make them worse off than they would have been if the choices had not been made. Hanser concludes his essay with a discussion of responsibility for acts that will affect the health of future offspring.     

Natural ways are better: Adolescents and the ‘anti-obesity’ gene

Empirical research with young people in Finland, Germany, Spain and Britain was carried out as part of the BIOCULT project funded by the European Union. The project focused on their attitudes to biotechnology and, in particular, the formation of arguments about risk and safety. This paper looks at the responses of 14–18 year olds to a story about the so called anti-obesity gene, in the form of advice to a friend who is taking it. The majority advised against taking it with some differences by gender and country. Most reservations were on grounds of safety and the feeling that ‘natural’ ways to lose weight are better: A minority questioned the idea of striving for a ‘perfect’ body. The types of arguments used by the young people reveal underlying perspectives on the place of human beings in the world and whether they have a right to manipulate nature and their own bodies. Marie Levitt is a sociologist with research interests in attitudes and values in relation to biotechnology, health and religion.     

Gender Differences in Intercepting A Moving Target by Using a Throw or Button Press

Humans are a throwing species just as much as a talking species (Calvin, 1982), but preadaptations for throwing remain largely unexplored. The ability of undergraduate students (N = 165) to intercept a stimulus with a thrown object was determined for 10 stimulus speeds, ranging from 2 to 5 m/s. The inclusion of a condition in which the moving stimulus was intercepted. via button press allowed the role of the perceptual aspect of velocity estimation to be evaluated separately from the act of throwing. Gender differences were observed in both the button and the throwing intercept tasks: The men had smaller timing errors and higher accuracy than the women. Contrary to expectations, the male and female patterns of intercept errors as a function of stimulus speed were more similar in the throwing task than in the button intercept task     

Schedule interactions involving punishment with pigeons and humans

The principal aim of the present experiments was to assess whether punishment increased or decreased the rate of unpunished behavior (contrast and induction, respectively) for which reinforcement rate was held constant, with physical and nonphysical punishers (electric shock and response cost), pigeon and human subjects, signaled and unsignaled components (multiple and mixed schedules), and the presence or absence of a blackout period between components. Across the three experiments there were 20 punishment conditions. Induction was found in nine of those, less consistent response-rate reduction was found in three, contrast was found in four, and in four there was no change in responding from conditions without punishment. Contrast occurred consistently only with multiple schedules during the first exposure to electric-shock punishment. Induction and no change, however, were found with every combination of the independent variables studied. Four conclusions regarding the interactions between punished and unpunished responding emerged from the present results: (a) Both contrast and induction occurred with the reinforcement rate held constant and a blackout between components, (b) induction was more common than contrast, (c) contrast occurred only in the presence of a stimulus different from that correlated with the punisher, and (d) contrast diminished with prolonged exposure to punishment. None of the current theoretical accounts of punishment contrast can explain the present results.
