客体动作承载性指人们知觉客体时同时激活的针对客体的行动。当Gibson最初提出动作承载性概念时, 他认为客体的这种属性是可以自动激活的。然而近年来越来越多的证据显示, 在知觉和行动的关系中, 行动语义知识和客体所处背景对客体动作承载性具有调节作用, 表现在人们可以根据这些自上而下的信息选择针对客体的适当的行动。此外, 不同的判断任务在引发客体动作承载性效应上具有特异性, 表现在若判断任务仅需知觉客体表层属性时, 不能激活对客体的动作, 进而不能产生客体动作承载性; 若判断任务需要对客体进行深层加工时, 才会激活对客体的动作。未来研究还需要进一步探究行动语义知识和客体所处背景影响客体动作承载性发生的原因和机制, 以及不同判断任务中出现结果特异性的原因。 相似文献

Despite the proliferation of civic education programs in the emerging democracies of Latin America, Africa, and Eastern Europe, there have been few recent evaluations of the effectiveness of civics instruction in achieving changes in democratic orientations among student populations. We present findings from a study conducted in 1998 that examined the impact of democratic civic education among South African high school students. Using a battery of items to gauge democratic orientations, including measures of political knowledge, civic duty, tolerance, institutional trust, civic skills, and approval of legal forms of political participation, we find that civic education had the largest effects on political knowledge, with the magnitude of the effect being approximately twice as large as the recent Niemi and Junn (1998 ) finding for the United States. Exposure to civic education per se had weaker effects on democratic values and skills; for these orientations, what matters are specific factors related to the quality of instruction and the use of active pedagogical methods employed by civics instructors. Further, we find that civic education changed the structure of students' orientations: a "democratic values" dimension coalesces more strongly, and in greater distinction, from a "political competence" dimension among students exposed to civic education than among those with no such training. We discuss the implications of the findings for our theoretical understanding of the role of civic education in fostering democratic attitudes, norms, and values, as well as the practical implications of the results for the implementation and funding of civic education programs in developing democracies in the future. 相似文献

An experience-grounded semantics is introduced for an intelligent reasoning system, which is adaptive, and works with insufficient knowledge and resources. According to this semantics, truth and meaning are defined with respect to the experience of the system – the truth value of a statement indicates the amount of available evidence, and the meaning of a term indicates its experienced relations with other terms. The major difference between experience-grounded semantics and model-theoretic semantics is that the former does not assume the sufficiency of knowledge and resources. This approach provides new ideas to the solution of some important problems in cognitive science. 相似文献

Abstract. Many question whether Islam and science can be compatible. In the first six hundred years of Islam, Muslims addressed all fields of knowledge available to them with unprecedented zeal and contributed immensely to the knowledge that became the precursor of the Renaissance in Europe. The Tatar invasion in the thirteenth century and the total destruction of Baghdad, the Muslim capital of knowledge and science, followed by the crusades, the ensuing hostility between East and West, and Western colonialism of Muslim countries led to a distrust of all knowledge emanating from the West. Such distrust closed the doors to ijtihad, a dynamic method in Islamic jurisprudence for addressing change, new demands, and new acquired knowledge, even though the Qur'an challenges Muslims to think, contemplate, understand, comprehend, and examine everything around them—tasks that bring humankind closer to God as they find methods to apply God's laws of justice and equity to the benefit of all humankind. Islam is the religion of yusr (ease) and not ‘usr (hardship). The creation of the world was for human benefit and use. Innovation for such beneficial use and application is a must. 相似文献

To ascertain the context of Il’enkov’s philosophy, the author delves into the history of philosophy since the Sophists and
Plato. For Il’enkov, philosophy is not an abstract science “about everything,” but a study of ideas – forms which are identical
for thinking and being. These objective and universal forms of thought are explained as products and schemes of human activity
creating the world of culture and reified in its “smart” things. 相似文献

采用特征主题的类别学习实验范式,考察了儿童类别学习中知识效应的年龄差异。63名小学4年级学生(年龄范围9~10岁)、65名小学6年级学生(年龄范围11~12岁)和77名初中2年级学生(年龄范围13~14岁)参加了本实验。结果表明:当类别特征能够在已有知识的基础上形成主题时,3个年龄组儿童类别学习的轮次和错误数均显著下降,而且主题突出时,这种趋势更加明显;在统一主题条件下,小学4年级、小学6年级和初中2年级3个年龄组儿童类别学习的轮次和错误数依次减少;而在无主题和突出主题条件下,3个年龄组儿童类别学习的成绩无显著差异。 相似文献
