The Effects Of Automation And Task Difficulty On Crew Coordination, Workload, And Performance, Ruth Coleen Thornton
Psychology Theses & Dissertations
The purposes of this research were two-fold: (1) to assess the reliability and utility of the Aircrew Coordination Observation and Evaluation scales in describing crew coordination behaviors exhibited during flight and (2) to investigate the effects of automation on crew coordination, workload, and performance. Two levels of automation (i.e., presence or absence of an autopilot) and two levels of task difficulty (i.e., presence or absence of wind and turbulence) were combined to yield a 2 x 2 design. Twenty-four two-person crews performed in both levels of automation and one of two levels of task difficulty. The results of the reliability …

Determinants Of Feedback-Seeking Behaviors, Melinda J. Montgomery
Psychology Theses & Dissertations
The purpose of the present research was to evaluate the effects of the level of task difficulty, the value of the goal, and the amount of effort required to obtain feedback on the frequency of feedback-seeking behaviors (FSB). The design was a 2 (task difficulty) x 2 (goal value) x 2 (effort) x 3 (day) mixed model analysis of variance. Eighty undergraduates were randomly assigned to one of eight experimental conditions. Each participant played a computerized stock market game for three "days". Three types of referent feedback and three types of appraisal feedback were available. The results indicated that more …
