Experimental research was conducted to examine the following three hypotheses of the model (a) the amount of information sought to make the rating is positively related to the number of rating scale categories, (b) this relationship is directly affected by previous rating experience, and (c) rating accuracy is positively related to the number of-rating scale categories. Undergraduate students, serving as subjects (Ss), were required to rate the competence of hypothetical college professors on the basis of information (typewritten statements) about their behavior. Ss were instructed to select as much information as they needed to rate each professor. Each S was assigned to one of four groups and participated in two consecutive rating sessions. In Session 1, depending on the group, is used either a two, four, six, or eight category scale to rate a set of eight professors. In Session 2, all Ss used an eight category scale to rate another set of eight professors. Two experiments were conducted, with different Ss participating in each experiment. The experiments differed in the effort needed to select information. An information selection score was calculated for each S in Session 1 and Session 2. The significant positive slopes of the linear regressions of these two measures on rating scale size in Session 1 were taken as support for the first two hypotheses. These significant results, however, were obtained only in the experiment with the more difficult information selection task, thus indicating the importance of the effort variable in moderating these relationships. An accuracy score was calculated for each S in Session 2. The slope of the linear regression of this measure on rating scale size in Session 1 was not significant, thus failing to provide support for the accuracy hypothesis. It was concluded that nearly perfect accuracy was achieved by all groups due to the redundancy of the information and that additional research must be conducted in order to properly evaluate the accuracy hypothesis. 1972 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1555931250429241 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1555931250429241 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
