This article queries whether consonant sonority (sonorant vs. obstruent) and status (coda vs. onset) within intervocalic clusters influence syllable-based segmentation strategies. We used a modified version of the illusory conjunction paradigm to test whether French beginning, intermediate, and advanced readers were sensitive to an optimal “sonorant coda–obstruent onset” sonority profile within the syllable boundaries as a cue for a syllable-based segmentation. Data showed that children used a syllable-based segmentation that improved with reading skills and age. The results are discussed to support that the visual letter detection within pseudowords primarily and early relies on acoustic-phonetic cues within the syllable boundaries, whereas the syllable effect seems to be developmentally constrained by reading skills and age.  相似文献

Abstract

Previous research on laterality in sport suggests an over-representation of left-handers in interactive sports such as tennis and cricket. These findings potentially reflect left-handers' advantage over their right-handed competitors in those sports. Although considered crucial for successful performance, the tactical component of their superiority has yet to be analysed. Two studies were conducted to test for a side bias in tennis players' tactical preferences. In the first study, 108 right- and left-handed players of varying skill watched rallies on a computer screen and had to indicate where they would place the ball in the opposing half. The results showed the tactical preference of players to place more balls on a left-handed opponent's mostly stronger forehand side compared with when faced with a right-hander. In the second study, 54 professional tennis matches involving right- and left-handers were analysed with respect to ball placement frequencies on the opponent's backhand side. Significantly fewer balls were hit to the backhand side of a left-handed opponent, thus replicating the findings of Study 1 in on-court situations. Both studies indicate players' preference to place shots to their right irrespective of their opponent's handedness. Findings support the assumption that left-handers might enjoy a strategic advantage in tennis.  相似文献

Summaries

The article presents an account of the personal experiences of the author during his participation in an American graduate programme in science education. The author describes the Ph.D. programme and the institution administering it i.e. the SESAME Group at the University of California at Berkeley. He outlines the important features of the programme in relation to admission requirements, course work, qualifying examination, and thesis research. This formal characterization is contrasted with his personal impression, and an attempt is made to evaluate the merits of his one‐year participation in the programme. In the final section, the possibilities and desirable modifications for an adequate adaptation of such a graduate programme in FR Germany or Europe are discussed.  相似文献

Bishop (1987) observed that being unable to answer a politicalknowledge question decreased self-reported interest in publicaffairs. This effect was unaffected by the introduction of upto 101 unrelated buffer items. In contrast, a single bufferitem that provided respondents with an external explanationfor their lack of knowledge greatly reduced the context effectin the present study. Implications for the operation of bufferitems are discussed.  相似文献

CONFIDENTIALITY ASSURANCES IN SURVEYS: REASSURANCE OR THREAT?   总被引:2,自引:0,他引:2  
Over the last three decades, the public's willingness to takepart in surveys has gradually declined, and the decline hasbeen attributed in part to increasing concern about the confidentialityof the data requested. This paper reviews the early literaturebearing on confidentiality assurances and willingness to respond,and then reports on three experiments designed to investigatethe effects of confidentiality on the expectations of respondentsand on their willingness to take part in a survey. The resultsof all three experiments confirm our expectation that confidentialityassurances are not always perceived as reassuring, and do notnecessarily increase the public's willingness to respond.  相似文献
