Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran
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 …
Assessing The Effectiveness Of An Interval Estimation And A Visual-Spatial Secondary Task As Measures Of Mental Workload During Laparoscopy, Levi Parker Warvel
Assessing The Effectiveness Of An Interval Estimation And A Visual-Spatial Secondary Task As Measures Of Mental Workload During Laparoscopy, Levi Parker Warvel
Psychology Theses & Dissertations
The goal of the present study was to compare two secondary workload tasks, specifically a time interval estimation and visual-spatial task, to determine which of these is most appropriate for the assessment of laparoscopic mental workload. Participants performed a peg transfer task in two conditions: a normal camera angle and a 90° camera angle intended to increase mental workload. Based on multiple resource theory, it was predicted the visual-spatial task would be more sensitive to the workload manipulation than the time estimation task because it draws upon the specific, as opposed to more general, attentional resources required by laparoscopy. Primary …
Categorizing Fetal Heart Rate Variability With And Without Visual Aids, Amanda Jane Ashdown
Categorizing Fetal Heart Rate Variability With And Without Visual Aids, Amanda Jane Ashdown
Psychology Theses & Dissertations
This present study examined the ability of clinicians and novices to correctly categorize fetal heart rate (FHR) variability with and without the use of exemplars. Clinicians and undergraduate students were asked to inspect FHR images and determine into which of four categories they belonged. Each participant took part in three conditions: one in which they were provided exemplars of prototypical FHR variability to use during their categorization task, another in which they were provided exemplars of nonprototypical FHR variability to use in their task, and a control condition in which no exemplars were available. The results showed that experts were …
