Behavioral commitment levels of group members were examined under conflict of interests between individual and collective tasks in a work-group scenario. Commitment was conceptualized as the amount of time and effort resources that individuals chose to allocate to the group task. Seventeen groups of three allocated 100 time and effort resource units to individual and group tasks for each of four trials. The level of commitment to group work increased, partially because over-rewarded persons increased group contributions more than underrewarded persons decreased them. However, the variance of allocations to the group task did not decrease over trials. Potential implications of the findings for organizational research and practice concerning work groups are discussed in terms of the roles of equity, comparative referent use, and information exchange. 相似文献

The effect of a server introducing herself by name on restaurant tipping was investigated. Forty-two, 2-person dining parties were randomly assigned to either a name or a no name introduction condition. The use of a buffet brunch reduced contact between server and diners and held bill size constant. Results indicated that having the server introduce herself by name resulted in a significantly higher tipping rate (23.4%) than when the server did not introduce herself by name (15.0%), p < .001. Tipping rate also was affected by method of payment, with diners who charged the meal having a higher rate (22.6%) than those paying cash (15.9%), p < .001. The findings suggest the importance of initial server-diner interactions. Possible alternative explanations and suggestions for future research are provided. 相似文献

This article describes the development of a structured nonverbal measure of personality based on Murray's (1938) system of needs. The items of the Nonverbal Personality Questionnaire consist of line drawings of a central figure performing trait-relevant behaviors in specific situations; respondents are asked to indicate the likelihood of engaging in similar behaviors. The nonverbal form was administered to three Canadian samples of respondents and one Finnish sample. Reliability and validity data for the initial item pool and for a revised form are reported. The utility of the nonverbal inventory for cross-cultural and theoretical work in personality is discussed. 相似文献

Cluster analysis refers to a family of methods for identifying cases with distinctive characteristics in heterogeneous samples and combining them into homogeneous groups. This approach provides a great deal of information about the types of cases and the distributions of variables in a sample. This paper considers cluster analysis as a quantitative complement to the traditional linear statistics that often characterize community psychology research. Cluster analysis emphasizes diversity rather than central tendency. This makes it a valuable tool for a wide range of familiar problems in community research. A number of these applications are considered here, including the assessment of change over time, network composition, network density, person-setting relationships, and community diversity. A User's Guide section is included, which outlines the major decisions involved in a basic cluster analyses. Despite difficulties associated with the identification of optimal cluster solutions, carefully planned, theoretically informed application of cluster analysis has much to offer community researchers.

Two groups of college students that scored high (N=25) and low (N=60) on a schizotypal personality index based on the Perceptual Aberration, Magical Thinking, and Schizotypal Personality
Scales, were tested for hemisphericity using a dichotic listening task and completed the Torrance Test of Creative Thinking.
The schizotypy scales correlated with high scores on the nonverbal portion of the creativity tests and with a left ear preference
to dichotically presented verbal stimuli. The Torrance Test of Creative Thinking did not correlate, however, with hemispheric
asymmetry. These results clarify the relationship between schizotypy and creating thinking abilities but fail in establishing
the role of hemispheric asymmetry in the production of creative thinking ideas.
This article is based on a portion of the first author’s dissertation at Wayne State University. 相似文献

The logic of the vertical blanking interval (VBL) Softswitch in the Apple Ilgs is the reverse of the logic of the VBL in the Apple IIe. Programs written for the Apple IIe that synchronize the videoscan with the experiment control program timing by sensing the VBL pulse will therefore function incorrectly when run on an Apple Ilgs. Procedures for modifying existing synchronization routines are discussed. A flexible alternative program that senses the type of computer on which it is running and accordingly adjusts the logic of the synchronization routine is described. 相似文献

Educationally significant behaviors of students, teachers, and supervisors were directly assessed daily for a fiscal year in a residential school in which the results of behavior analysis research are applied to all levels of schooling. The variables assessed included those found to be concomitantly related to effective schooling as determined by the educational research literature, and functionally related to effective teaching as determined by the literature of behavior analysis. Weekly summaries of the following variables were analyzed for each of two daily shifts of teachers and supervisors: (a) number of trials presented and correct number of trials, (b) number of instructional sessions conducted, (c) number of learning objectives achieved, (d) percentage correct in each of three curricular areas, (e) weekly teacher observation scores, and (f) the total and rate per hour of supervisors' task accomplishments. There were strong positive correlations between: (a) instructional sessions and learning objectives, (b) teachers use of behavioral techniques in weekly observations by supervisors and students' achievement, (c) number of supervisor tasks completed and number of instructional sessions conducted by teachers, (d) number of teacher observations by supervisors and teachers' performance during observations, and (e) number of student objectives attained and number of tasks completed by supervisors. The assessment is the most comprehensive and sustained analysis of the daily behaviors of schooling. The relationships found between students and teacher behaviors replicate the effects of numerous experiments but do so in a total school setting. The relationships found between supervisor and student behavior have not been demonstrated in prior research. There is a need for similar school wide assessments in other types of schools to determine the generality of the relationships obtained in the present article. 相似文献
