Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers Dec 2019

Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers

Psychology Theses & Dissertations

Research on the effects of interruptions shows that they can be either costly or beneficial depending on which aspects of an interruption are manipulated. One important aspect that contributes to these conflicting results concerns when an interruption occurs. The present study explored how event segmentation theory (EST) can be used to determine optimal moments for an interruption relying on hierarchical task analysis (HTA) to identify coarse and fine event boundaries. Utilizing a 2 X 3 mixed design, undergraduate students completed a trip planning task divided into three task trials. The within-subjects factor was interruption timing, which had three levels: none, …


The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman Jul 2019

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) …
