A New Method To Determine The Posterior Distribution Of Coefficient Alpha, John Mart V. Delosreyes
A New Method To Determine The Posterior Distribution Of Coefficient Alpha, John Mart V. Delosreyes
Psychology Theses & Dissertations
There is a focus within the behavioral/social sciences on non-physical, psychological constructs (i.e., constructs). These constructs are indirectly measured using measurement instruments that consist of questions that capture the manifestations of these constructs. The indirect nature of measuring constructs results in a need of ensuring that measurement instruments are reliable. The most popular statistic used to estimate reliability is coefficient alpha as it is easy to compute and has properties that make it desirable to use. Coefficient alpha’s popularity has resulted in a wide breadth of research into its qualities. Notably, research about coefficient alpha’s distribution has led to developments …
The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry
The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry
Psychology Theses & Dissertations
Interruptions are a common problem for attention and pose a threat to visual task performance. The Memory for Goals (MFG) theory suggests that strongly and accurately encoded cues can assist the ability to resume a primary task after an interruption (Altmann & Trafton, 2002). Encoded cues can undergo an activation decay during an interruption and become forgotten. Currently, there has been limited research on how visual interruptions affect cued recall within a dynamic environment. Thus, the goal of the present study was to examine the effect of cuing and task interruptions on change detection within dynamic scenes. Undergraduate students watched …
The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman
The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman
Psychology Theses & Dissertations
Because automation use is common in many domains, understanding how to design it to optimize human-automation system performance is vital. Well-calibrated trust ensures good performance when using imperfect automation. Two factors that may jointly affect trust calibration are automation transparency and perceived reliability. Transparency information that explains automated processes and analyses to the operator may help the operator choose appropriate times to shed task control to automation. Because operator trust is positively correlated with automation use, behaviors such as task shedding to automation can indicate the presence of trust. This study used a 2 (reliability; between) × 3 (transparency; within) …
Development And Validation Of The Cultural Competence Of Program Evaluators (Ccpe) Scale, Krystall Dunaway
Development And Validation Of The Cultural Competence Of Program Evaluators (Ccpe) Scale, Krystall Dunaway
Psychology Theses & Dissertations
As part of its Guiding Principles for Evaluators, the American Evaluation Association (AEA) requires that evaluators develop cultural competencies, yet no measure of cultural competence currently exists in the field. Using items from cultural competence measures used in fields such as counseling and nursing, in conjunction with the creation of qualitative questions, the researcher developed the Cultural Competence of Program Evaluators (CCPE) scale. The main goal of this study was to validate the CCPE, and a subsidiary goal was to assess differences in level of cultural competence among program evaluators based on various demographic variables such as minority status, age, …
The Effects Of Operator Trust, Complacency Potential, And Task Complexity On Monitoring A Highly Reliable Automated System, Nathan R. Bailey
The Effects Of Operator Trust, Complacency Potential, And Task Complexity On Monitoring A Highly Reliable Automated System, Nathan R. Bailey
Psychology Theses & Dissertations
Technological advances have allowed for widespread implementation of automation in complex systems. However, the increase in quantity and complexity of advanced automated systems has raised a number of potential concerns including degraded monitoring skills. The present investigation consisted of two studies that assessed the impact of system reliability, complacency potential, monitoring complexity, operator trust, and system experience on monitoring performance. In both studies, participants monitored a simulated aviation display for failures while operating a manually controlled flight task. In addition, the second experiment assessed the ability of operators to detect a single automation failure over three experimental sessions. Results indicated …
