Prolongation of speech sounds is currently used to modify stuttering and enhance fluency. Prolonged speech (PS) (e.g., prolonged vowels, prolongation throughout utterances) is, however, often perceived as unnatural by listeners. This study examined at which durations and in which contexts 52 college students (primary language was American English) perceived PS to be unnatural. Stimuli were limited to controlled variation in prolongation of the vowel in the middle single-syllable word of a carrier phrase (i.e., say word again). The prolongation was effected by digital waveform manipulation within the Kay Elemetrics Computerized Speech Laboratory (CSL). The listeners judged if they strongly agreed, agreed, or disagreed that the phrases sounded natural. Results indicated that the extent of vowel duration (and possibly context) does influence listener's perception of speech naturalness, findings which can be applied to facilitate fluency therapy.
Educational objectives: (1) The reader will learn about and be able to summarize the digital waveform manipulation procedure in the study. (2) The reader will learn about and be able to describe the effects of differential vowel prolongation on listener's perception of speech naturalness. (3) The reader will learn about and evaluate how differential vowel prolongation can be used to enhance fluency. 相似文献

Affective, Continuance, and Normative Commitment to the Organization: An Examination of Construct Validity 总被引:6,自引:0,他引:6
Within the past few years, several studies have used the Affective, Continuance, and Normative Commitment Scales (Allen & Meyer, 1990; Meyer & Allen, 1984, 1991) to assess organizational commitment. The purpose of this paper is to review and evaluate the body of evidence relevant to the construct validity of these measures. Although some empirical questions remain at issue, the overall results strongly support the continued use of the scales in substantive research. 相似文献

Naturalistic one-to-one tutoring is more effective than traditional classroom teaching methods, but there have been few attempts to examine the features of normal tutoring that might explain its advantage. This project explored dialogue patterns in two samples of naturalistic tutoring with normal unskilled tutors (as opposed to expert tutors): graduate students tutoring undergraduates in research methods and high school students tutoring 7th graders in algebra. We analysed the extent to which those tutoring protocols manifested components that have been emphasized in contemporary pedagogical theories and intelligent tutoring systems: active student learning, sophisticated pedagogical strategies, specific examples and cases, collaborative problem solving and question answering, deep explanatory reasoning, convergance toward shared meanings, feedback, error diagnosis and remediation, and affect. The most prominent components consisted of collaborative problem solving, question answering, and explanation in the context of specific examples. We identify frequent dialogue patterns that characterize these collaborative processes. 相似文献

Traditional approaches to inhibited sexual hire (ISD)—which may be exclusively heterosexist, erotophobic, sexist, and homophobic—fail to adequately address ISD within the lesbian population, in which incest and substance abuse occur commonly. Successful treatment of ISD among lesbians requires awareness of sexual minority customs, lesbian psychologies, and recovery agendas. 相似文献

This study suggests that sex stereotypes implicitly enacted, but never explicitly articulated, in TV commercials may inhibit women's achievement aspirations. Men and women (N=180) viewed locally produced replicas of four current, sex-stereotyped commercials, or four replicas that were identical except that the sex roles were reversed, or (control) named their favorite TV programs. All subjects then wrote an essay imagining their lives “10 years from now.” The essays were coded for achievement and homemaking themes. Women who viewed traditional commercials deemphasized achievement in favor of homemaking, compared to men and compared to women who had seen reversed role commercials. The reversed role commercials eliminated the sex difference in net achievement focus. Control subjects were indistinguishable from their same-sex counterparts in the traditional condition. The results identified some social changes needed to make “equality of opportunity” a social reality for women as well as men. 相似文献

Rising sea levels may sink entire countries. Individualistic solutions to this climate catastrophe, such as those proposed by Meisels and Risse, are inadequate on both Kantian and Lockean criteria. This article concurs with Cara Nine's recent argument that such ‘ecological refugee states’ are entitled to territorial remedies. But Nine's proposal, founded on Locke's ‘sufficiency’ proviso and Nozick's famous application of it to waterholes in the desert, is instructively incorrect. Careful consideration of the distinction between land and territory, and of the structure of Proviso arguments, supports a new theory of how territorial claims can be positive‐sum — how the amount of territory can increase even as the land base remains constant or decreases. This normative conception of territory as the ratio of justice to land use provides a better foundation for a political solution to the problem of ecological refugee states and also generates deeper insight into the nature of territory itself. The article thus contributes not only to our thinking about redress for ecological refugees, but also to the burgeoning literatures on territory and on the Lockean Provisos. 相似文献
