The role of prosodic boundaries in the resolution of lexical embedding in speech comprehension 总被引:6,自引:0,他引:6
Participants' eye movements were monitored as they heard sentences and saw four pictured objects on a computer screen. Participants were instructed to click on the object mentioned in the sentence. There were more transitory fixations to pictures representing monosyllabic words (e.g. ham) when the first syllable of the target word (e.g. hamster) had been replaced by a recording of the monosyllabic word than when it came from a different recording of the target word. This demonstrates that a phonemically identical sequence can contain cues that modulate its lexical interpretation. This effect was governed by the duration of the sequence, rather than by its origin (i.e. which type of word it came from). The longer the sequence, the more monosyllabic-word interpretations it generated. We argue that cues to lexical-embedding disambiguation, such as segmental lengthening, result from the realization of a prosodic boundary that often but not always follows monosyllabic words, and that lexical candidates whose word boundaries are aligned with prosodic boundaries are favored in the word-recognition process. 相似文献

结构对称性汉字视觉识别特点的实验研究 总被引:13,自引:2,他引:11
用命名作业通过二个实验考察了结构对称性汉字的视觉识别特点,结果表明,汉字识别具有显著的结构对称性效应,识别结构对称性汉字的加工明显快于非对称性汉字,对称性效应与字频效应,笔画效应具有显著的交互作用,进一步的简单效应的分析表明,这种结构对称性效应在低频字中起作用,而在高频字中不起显著作用;在多笔画字中起作用,而在少毛画字中不起显著作用,这表明,对称性汉字中的具有冗余信息的格式塔部件促进地识别汉字的加 相似文献

The objective of this study is to examine the factor structure and psychometric properties of the SPAI in a sample of adolescent Spaniards. The results obtained support the use of the correlated two-factor SPAI subscales and indicate high coefficient alpha values for the SPAI subscales. The results provide support for the use of the SPAI in an adolescent population in a non-English-speaking country. Both exploratory and confirmatory factor analyses of the Social Phobia subscale showed a four-factor structure, instead of a five-factor dimension, as suggested by previous studies. Effects for gender and age and gender interaction were found. Limitations and suggestions for future research are discussed. 相似文献

Two algorithms based on a latent class model are presented for discovering hierarchical relations that exist among a set ofK dichotomous items. The two algorithms, stepwise forward selection and backward elimination, incorporate statistical criteria for selecting (or deleting) 0–1 response pattern vectors to form the subset of the total possible 2
k
vectors that uniquely describe the hierarchy. The performances of the algorithms are compared, using computer-constructed data, with those of three competing deterministic approaches based on ordering theory and the calculation of Phi/Phi-max coefficients. The discovery algorithms are also demonstrated on real data sets investigated in the literature. 相似文献

In three-mode Principal Components Analysis, theP ×Q ×R core matrixG can be transformed to simple structure before it is interpreted. It is well-known that, whenP=QR,G can be transformed to the identity matrix, which implies that all elements become equal to values specified a priori. In
the present paper it is shown that, whenP=QR − 1,G can be transformed to have nearly all elements equal to values spectified a priori. A cllsed-form solution for this transformation
is offered. Theoretical and practical implications of this simple structure transformation ofG are discussed.
Constructive comments from anonymous reviewers are gratefully acknowledged. 相似文献

The paper justifies the concept of “thematic structure” or “order of knowledge” over the traditional “classification of sciences”
due to the uncertainty of many classification criteria. The thematic structure of science has, of course, various levels and
various dimensions. Arguments against any forms of separating the humanities from sciences in the traditional sense of the
term are presented and discussed. Equally unacceptable are attempts at sharp separation of technical disciplines and humanities.
The thematic structure of humanities is not created by some material aspects but rather through the interest — or problem-oriented
aspects. In addition to the natural sciences and the humanities there exists an important sphere of sciences on artefacts
or, using the term by H. Simon, the sciences of the artificial. For the contemporary research activities is typical what could
be denoted as “interdisciplinary or multidisciplinary complex.” The paper traces a set of epistemological criteria for the
justification of the relative independence of a scientific discipline.

This study examined the factor structure, validity, and reliability of the Fear Questionnaire in Hong Kong. The sample consisted of 226 college students who were ethnic Chinese and they came from different parts of Hong Kong. Exploratory factor analysis produced three meaningful factors. Confirmatory factor analysis supported the three-factor model of Marks and Mathews (1979) in the present sample of subjects. Findings also showed that the Fear Questionnaire was both reliable and valid. Limitations of the study and implications for future research in this area were discussed. In particular, the need to assess the cross-cultural application of the Fear Questionnaire was stressed.This research project was supported by the Research and Conference Grants of the University of Hong Kong. 相似文献

优、差生解决有机合成的问题表征差异及其影响因素 总被引:8,自引:0,他引:8
用两个实验探讨了大学本科化学专业优生和差生解决有机合成问题所运用的问题表征的类型及其差异。结果表明:(1)大学生解决有机合成的问题表征有三种类型;符号表征、方法表征和机理表征。(2)优生能灵活运用上述三类问题表征,特别是运用机理表征抓住问题的关键,进而采用方法表征和符号表征来解题;差生则停留于符号表征和方法表征。很少采用机理表征,而方法表征又往往选择错误,因而不能正确解题。(3)优,差生在问题表征上的差异与其知识总量和知识结构有密切相关。 相似文献
