汉语词类歧义解决(Ⅱ) 总被引:1,自引:0,他引:1
采用眼动记录阅读范式,考察汉语词类歧义解决过程。阅读材料为含有单字词类歧义词的句子,歧义词前面的语境不提供明确的偏向性信息,后语境提供解歧信息。结果发现,当后语境支持次要用法时,歧义词及后面第一个解歧区的总阅读时间加长,歧义词后第二个解歧区的回扫次数增多,而当后语境支持主要用法时没有出现类似的现象,表明相对频率能够即时影响词类歧义解决过程,结果支持基于制约的模型。文章对汉语词类歧义解决过程、不同实验技术及其引起的差异进行了讨论。 相似文献

Since the late 1960s, there has been steady, progressive change in the depiction of gender in award-winning picture books for children (e.g., Clark, Almeida, Gurka, & Middleton, 2003). Female characters in Caldecott winners and runners-up have become increasingly visible and gender stereotyping has become decreasingly evident. In this article we consider whether this steady change can be projected back into the decades before the 1960s, or whether local, temporal variation in gender norms affected less monotonic change. We found that Caldecotts of the late 1940s and the late 1960s had fewer visible female characters than Caldecotts of the late 1930s and the late 1950s, but that characters in the 1940s and 1960s were less gender stereotyped than the characters of the 1930s and 1950s. We interpret these findings in terms of the greater level of conflict over gender roles that existed in the 1940s and 1960s, as well as the relatively greater status enjoyed by American women in those decades. 相似文献

Early vocabulary development is a reliable predictor of children's later language skills. The MacArthur-Bates Communicative Development Inventory (CDI) has provided a powerful tool to assess earlyvocabulary development in English and other languages. However, there have been no published CDI norms for Mandarin Chinese. Given the importance of large-scale comparative data sets for understanding the early childhood lexicon, we have developed an early vocabulary inventory for Mandarin. In this article, we report our efforts in developing this instrument, and discuss the data collected from 884 Chinese families in Beijing over a period of 12-30 months, based on our instrument. Chinese children's receptive and expressive lexicons as assessed by our inventory match well with those reported for English on the basis of CDI. In particular, our data indicate comprehension-production differences, individual differences in early comprehension and in later production, and different lexical development profiles among infants versus toddlers. We also make the checklists and norms of our inventory available to the research community via the Internet; they may be accessed from the Psychonomic Society's Archive of Norms, Stimuli, and Data, at www.psychonomic.org/archive. 相似文献

The purpose of this study is to find a formula that describes the relationship between item exposure parameters and item parameters in computerized adaptive tests by using genetic programming (GP) – a biologically inspired artificial intelligence technique. Based on the formula, item exposure parameters for new parallel item pools can be predicted without conducting additional iterative simulations. Results show that an interesting formula between item exposure parameters and item parameters in a pool can be found by using GP. The item exposure parameters predicted based on the found formula were close to those observed from the Sympson and Hetter (1985) procedure and performed well in controlling item exposure rates. Similar results were observed for the Stocking and Lewis (1998) multinomial model for item selection and the Sympson and Hetter procedure with content balancing. The proposed GP approach has provided a knowledge‐based solution for finding item exposure parameters. 相似文献

This paper proposes an on‐line version of the Sympson and Hetter procedure with test overlap control (SHT) that can provide item exposure control at both the item and test levels on the fly without iterative simulations. The on‐line procedure is similar to the SHT procedure in that exposure parameters are used for simultaneous control of item exposure rates and test overlap rate. The exposure parameters for the on‐line procedure, however, are updated sequentially on the fly, rather than through iterative simulations conducted prior to operational computerized adaptive tests (CATs). Unlike the SHT procedure, the on‐line version can control item exposure rate and test overlap rate without time‐consuming iterative simulations even when item pools or examinee populations have been changed. Moreover, the on‐line procedure was found to perform better than the SHT procedure in controlling item exposure and test overlap for examinees who take tests earlier. Compared with two other on‐line alternatives, this proposed on‐line method provided the best all‐around test security control. Thus, it would be an efficient procedure for controlling item exposure and test overlap in CATs. 相似文献
