A modification of the WGTA is described. It retains those features of the original apparatus which make it efficient. In addition, it provides (1) precise and largely automatic control of trial pacing and stimulus presentation, (2) simultaneous acquisition of data on problem-solving and locomotor activity of the S, (3) rapid change to any one of a wide variety of behavioral situations, and (4) thorough but quick cleaning and disinfection of the monkey cage. 相似文献

The present study sought to investigate the effects of smoking on the speaking fundamental frequency of adult women. The results indicated that, in the reading condition, fundamental frequency for the smokers was significantly lower than fundamental frequency for the nonsmokers. Eighty-seven percent of the smokers examined by an otolaryngologist exhibited some abnormality in appearance of the vocal folds. The results also suggest that menopause may contribute to a lowering of the speaking fundamental frequency of adult women. 相似文献

Many of the topics of interest in the social and behavior sciences are often hierarchical or multilevel in nature. These multiple
levels (e.g., individual versus group) create problems for researchers related to the choice of measurement and analysis.
Recent innovations in statistical analysis have made it possible to account for the hierarchical nature of observations. Therefore,
in this article we begin with a review of multilevel analysis techniques and discuss advances that have been made in the social
sciences using multilevel models. Next, we summarize contemporary research specific to the organizational psychology literature
that uses multilevel analysis. Possible applications for industrial and personnel psychology are then discussed. Guidelines
for determining if multilevel analysis is appropriate for a given applied research project are provided. We conclude with
a summary and call for increased use of multilevel analysis in industrial and personnel psychology. 相似文献

A software system (NOVA SKED) was developed for the experimental control and collection of data from operant behavior experiments that is compatible with the Data General Corporation real-time disk operating system (RDOS). NOVA SKED is based on the SKED state notation language originally implemented on Digital Equipment Corporation PDP-8 series of minicomputers. The system includes a compiler written in FORTRAN, a multitasking run-time system that can be configured to run up to 30 stations, a data back-up system, standard data manipulation programs and subroutines, and user manuals. 相似文献

This paper examines the relationship between the smoking hehavior of supervisors and the effectiveness ratings attributed to them by their subordinates on 5 leadership eflectiveness measures. A sample of 3.422 assessments revealed that supervisors who smoke were rated lower than were nonsmoking supervisors. The findings suggest that smoking tobacco is associated with lower supervisory effectiveness, as perceived by subordinates. The causes for such lower ratings are attributed to bias against smokers in the workplace. actual performance differences, or both. 相似文献
