Comparing The Effects Of Task Experience And Interruption Source On Resumption Performance, Sarah Anastazia Powers
Comparing The Effects Of Task Experience And Interruption Source On Resumption Performance, Sarah Anastazia Powers
Psychology Theses & Dissertations
The timing of an interruption can be disruptive to task performance; however, the effect of participant control over when interruptions occur is not well understood. Further, it is unclear how participants’ experience with the primary task influences when they decide to address interruptions. Utilizing a 2 (task experience, between subjects) X 3 (interruption source, within subjects) mixed design, undergraduate students who had different amounts of experience with a computer-based medication dosage calculation task completed three trials of the task: once with the experimenter scheduling interruptions to occur at coarse breakpoints within the task, once with the participants deciding when to …
Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers
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 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 …
