Research examined both the Position Analysis Questionnaire (PAQ) and the possible analyst sources for gathering job analysis information. 25 state government jobs were examined using job incumbents, supervisors, job analysts, and a comparison group of college students. Reliability and validity (judge convergence and prediction of present pay levels) information was determined for each of the four analyst categories. Results indicate that there is little difference between analyst sources, including students, in terms of their ability to reliably analyze a job using the PAQ. Convergent validity results showed a high degree of agreement among all judge categories when summing item frequencies across all 25 jobs. The prediction of present pay levels was significant for all judge categories but was noticeably smaller than previously reported studies. This seemed to be primarily due to the restriction in salary range of the present study. An analysis of judge response bias showed that supervisors and incumbents rate all or most PAQ items higher than their analyst counterparts. These findings suggest that who furnishes responses to a job analysis inventory makes little practical difference. The exception is that the determination of pay levels and human requirements for test construction purposes should be viewed with caution when different analyst sources are utilized for different jobs. 相似文献

A review of the effects of noise on human performance 总被引:4,自引:0,他引:4
ANDREW SMITH 《Scandinavian journal of psychology》1989,30(3):185-206
The present review is concerned with the effects of noise, especially moderate intensity noise on performance. The review covers recent empirical results and theoretical approaches, and examines the importance of the nature of the noise, individual differences in response to noise, and other factors which modify the effects of noise. A central theme of the review is that it is essential to consider the nature of the task being performed in noise, and a profile of strategies of performance in noise is presented. Finally, recommendations are made about the direction and methodology of future research. 相似文献

A novel single-attribute test between competing expectancy-value models of attitude was devised using subjects' ratings of clusters of statements located at a range of points within a three-dimensional semantic space with expectancy, value and attitude as the co-ordinates. The data provided strongest support for a model using bipolar scoring for evaluation and unipolar scoring for expectancy. 相似文献
