Item Effect of psychosocial variables on maximum acceptable weight of lift(Texas Tech University, 1986-12) Selan, Joseph LThe objectives of this study were (l) to determine the effects of personality type in conjunction with social facilitation effects on the psychophysically-determined maximum acceptable weight of lift (MAWL), and 2) to establish guidelines for the psychophysical approach which control for the effects of psychosocial factors. To accomplish this, a laboratory study was conducted using 15 male subjects classified as Type A personalities (aggressive, impatient) and 15 Type B subjects (passive, patient). Following a training period, the subjects performed 5 psychophysical lifting tasks consisting of a floor to 30 inch lift using various frequencies of lift. (For the social facilitation manipulation, the subject lifted the box under 3 conditions: alone (box lowered automatically), with a confederate of similar physical ability lowering the box, and with a confederate of superior physical ability lowering the box^ The confederate conditions were introduced under the guise that the lowering apparatus was broken. Results indicated that Type A subjects worked at a higher percentage of their physical work capacity and selected heavier MAWLs than Type B subjects. Type A subjects required significantly less time deciding their MAWL, and made fewer weight adjustments in terms of decreasing box weight, than Type B subjects. Significant social facilitation effects were not obtained, nor was there a significant personality type x social condition interaction.Item Social facilitation in vigilance: coaction and evaluation effects(Texas Tech University, 1977-08) Roth, James ThomasNot availableItem Social facilitation of an operant response in mongrel dogs: the effects of model dominance(Texas Tech University, 1978-05) Brummett, Richard DavidNot availableItem Social factors and common group involvement of Texas Tech University students(Texas Tech University, 1987-12) Dedmon, JanaLee DownumA Worker Motivation Scale (WMS) was designed by Johnson, McDonald, and George (1985). This scale ranks an individual on his/her motivation for performing in a task oriented group. To evaluate its performance in scaling university students and the social group they belong to, the WMS was tested and correlated to general topics in group behavior. Hypotheses based on these statistical correlations were proposed, and were then supported or refuted. The WMS contained three subscales, on which a student scored high on one. The subscales included: (1) the Prominence Motivation (PM) person, who was motivated to be a leader in the group; (2) the Task Motivation (TM) person, who preferred that the group accomplish its goal or task; and (3) the Affiliation Motivation (AM) person, who enjoyed being a part of the group. It was hypothesized and supported that a PM student was likely to be a leader and felt he/she could change group opinion. It was also hypothesized and partially supported that the AM individual would feel pressure to conform to the group and would be influenced by the group. In addition, an exploratory factor analysis was done to describe the university student's motivation in social group participation in the university setting. Three factors were determined. The first factor was Affect Cohesion; in which the student had a high need for meeting emotional needs. The Amiability factor described the student's need for pleasantness. The Individualist factor included some of the disadvantages of being in a group. This thesis therefore introduced some new insights into why the university student belonged to social groups.
