Helping Employees Help The Environment: An Intervention To Increase Environmental Organizational Citizenship Behaviors (Ocb-E) Via A Subtle Stimulus, Rebecca C. Garden

Psychology Theses & Dissertations

Researchers’ understanding of the relationships between environmentally-oriented organizational citizenship behaviors (i.e., OCB-Es) and other workplace variables have improved since the turn of the century, but both our comprehension of the behaviors and the effectiveness of interventions targeting them require much more investigation. Further, there is very little research that examines the role of positive affect in promoting these behaviors, even though scholars have suggested that it may be the “silver bullet” (Kals & Müller, 2012) to facilitating employees’ voluntary environmental actions. To that end, the aim of the current research is to take an initial step towards understanding how organizations …

Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran

Psychology Theses & Dissertations

The purpose of this study was to test Wickens’ Multiple Resource Theory (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of transferring rings from one peg to another and a low workload task that consisted of grasping and placing large pencil erasers in a bowl. It was predicted that the visual-spatial secondary task would be more sensitive when paired with the laparoscopic primary task than the auditory analog. Findings …

The Influence Of Time Pressure And Information Load On Rule-Based Decision-Making Performance, Brooke Browne Schaab

Psychology Theses & Dissertations

Performance was evaluated under varying levels of time pressure and information load to determine their influence on simple rule-based decision-making. Consistent errors, biases, and heuristics found in human decision-making have been attributed to attempts to reduce attentional demands and to the limitations of working memory. Do these same mistakes occur when little or no demand is placed on working memory and the decision is made by following a set of simple rules? Using a simulation of a radar operator's task, 96 participants monitored a display for 24 min. Time pressure was manipulated by increasing or decreasing the number of aircraft …

The Effects Of Training And Feedback Format On Reactions To In-Basket Feedback And On In-Basket Performance, Michael G. Fedorko

Psychology Theses & Dissertations

The purpose of this research was to investigate the effects of training and feedback format on reactions to in-basket feedback and on in-basket performance. Performance was evaluated with a 2 (Training) x 3 (Feedback) x 2 (In-Basket) x 5 (Dimension) repeated measures factorial design. Reactions were evaluated with a 2 (Training) x 3 (Feedback) x 2 (Questionnaire) repeated measures factorial design. The Training factor was comprised of frame-of-reference training (designed to prepare the recipient to receive the feedback) and a control condition (a lecture on Mintzberg's managerial role classification system). The Feedback factor was comprised of written feedback, oral feedback, …

Comparison Of The Efficacy Of General And Specific Performance Dimensions In An Operational Assessment Center, Wanda J. Campbell

Psychology Theses & Dissertations

The purpose of this research was to compare the effectiveness of three general performance dimensions and 14 specific dimensions on various aspects of rating quality.

The categorization phase of the research tested the hypothesis that categorization accuracy and reliability would be a significantly greater for the general performance dimensions than for the specific dimensions. The results provided partial support for this hypothesis.

The aggregation phase of the research tested the following hypotheses: (1) rating accuracy would be greater when relevant behaviors were displayed with high frequency than when they were displayed with low frequency; (2) rating accuracy would be greater …

Hemispheric Effects Of Response Hand And Concurrent Auditory And Visual Information Processing On Task Performance, Paula J. Guerette

Psychology Theses & Dissertations

Previous research (cf. Wickens, Mountford & Schreiner, 1981; Wickens & Sandry, 1982) has suggested that performance is facilitated by maintaining "integrity" between the hemisphere of information input, processing, and motor response. This task-hemispheric integrity has been found to exist during concurrent performance of verbal and spatial tasks, both of which are presented in a visual modality. The present study sought to examine whether task-hemispheric integrity exists during concurrent performance of a verbal and a spatial task when the verbal task is presented in an auditory modality and the spatial task(s) are presented in a visual modality. Fifty-six individuals (28M, 28F) …
