汉字是由音、义、形三个基本因素构成的复合体。它是以字詞的語言构造和对象意义为基础、以文字符号为形式而組成的一个有机整体。就字形来說,又是由各种基本笔划、偏旁部首、基本字根据汉字結构規則組成的一个个文字。所謂正确牢固地掌握汉字不仅包括熟記字形的完整結构,而且要形成該字的音义形三者紧密联系的統一整体,最后达到 相似文献

To test whether newborn babies take account of external forces in moving their limbs, spontaneous arm-waving movements were measured while the baby lay supine with its head turned to one side. Free-hanging weights, attached to each wrist by strings passing over pulleys, pulled on the arms in the direction of the toes. The results showed the babies applied compensatory forces to keep the hand they faced moving in the same region. In contrast, the (invisible) contra-lateral hand was pulled down by the weights. In a second experiment, where the arms were occluded, both arms were pulled down, suggesting that sight of the arm was necessary in compensating for the weight. In a third, conclusive experiment the babies viewed the arm they were not facing on a small video-monitor and this time the babies kept the visible contra-lateral hand up despite the weights. The results challenge the general view that spontaneous arm movements of neonates are purposeless and either reflexive or due to spontaneous patterned efference to the muscles. Instead, the findings suggest that in waving their arms, neonates are developing visual control of reaching. 相似文献

The authors examined the concept of vengeance from a prototype perspective. In 6 studies, the prototype structure of vengeance was mapped. Sixty‐nine features of vengeance were identified (Study 1), and rated on centrality (Study 2). Further studies confirmed the prototype structure. Compared to peripheral features (e.g., religion, shame, and self‐esteem), central features (e.g., humiliation, honor, and power) were more often recalled and recognized in memory tests (Study 3), classified as vengeance more often and faster (Study 4), and rated higher in participants' autobiographical vengeance recalls (Studies 5 and 6). Lay conceptions of vengeance included the view that vengeance is planned, personal, and aggressive, and involves intense feelings of anger, humiliation, envy, and vindictive feelings, as well as negative thoughts. 相似文献

According to the main tradition in epistemology, knowledge is a variety of justified true belief, justification is an undefinable normative concept, and epistemic principles (principles about what justifies what) are necessary truths. According to the leading contemporary rival of the tradition, justification may be defined or explained in terms of reliability, thus permitting one to say that knowledge is reliable true belief and that epistemic principles are contingent. My aim here is to show that either of these approaches will yield a solution to the problem of induction. In particular, either of them makes it possible to ascertain the reliability of induction through induction itself. Such a procedure is usually dismissed as circular, but I shall argue that it cannot be so dismissed if either approach is correct.
As one would expect, the solution based on the traditional approach differs from the one based on the reliabilist alternative, but they have important features in common. The common elements are presented in sections I, II, and III, the elements specific to the reliabilist approach in sections IV, V, and VI, and those specific to the traditional approach in section VII. 相似文献
