中澳管理者人格类型的性别差异研究

采用MBTI对中国和澳大利亚管理者人格类型的性别差异进行了比较研究.结果表明,在人格的维度、维度组合、类型上,澳大利亚管理者比中国管理者有更大的性别差异;而两国男性管理者在人格的维度、维度组合、类型上的差异比两国女性管理者的差异更大.研究同时发现,中国男、女管理者人格类型的分布都较集中,澳大利亚男、女管理者的人格类型分布都较均衡.     

Attitude learning through exploration: advice and strategy appraisals

Processes of attitude learning were investigated through a game requiring discrimination between good and bad objects, where feedback about object valence (involving gain or loss) is contingent on approach. Previous research demonstrates a preponderance of false‐negative errors, with some good objects (‘learning asymmetry’) and most novel objects (‘generalization asymmetry’) being judged as bad, but provides no direct evidence concerning how participants appraise alternative strategies and their own performance. To compare alternative strategies, participants received advice, supposedly from a previous participant, that most objects were bad and should be avoided, or good and should be approached. Learning and generalization asymmetries were replicated, especially among participants who followed the former (risk‐averse) advice. Additionally, participants' evaluations of their own game strategy were inversely related to amount of negative feedback (the number of bad objects approached), but unrelated to positive feedback (from good objects approached), pointing to the salience of negative information for self‐appraisals.

The effects of differential vowel prolongations on perceptions of speech naturalness

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.     

Affective, Continuance, and Normative Commitment to the Organization: An Examination of Construct Validity

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.     

TV commercials as achievement scripts for women

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.
