Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich Jan 2005

Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich

Electronic Theses and Dissertations

This study investigated the effects of cross-modality warning presentation and retention in a dual-task paradigm in a simulated military environment under various task-induced stress levels. It was also intended to determine what role working memory played in the mode of warning presentation that resulted in the highest retention and subsequent compliance. An all within participant design was created in order to determine if scores on working memory span tasks predicted performance across the varying forms of warning presentation. Furthermore, task-induced stress levels were varied over the course of the experiment to identify if workload transitions affected performance. Results revealed that …


Resource Allocation Using Touch And Audition, David Mortimer Jan 2005

Resource Allocation Using Touch And Audition, David Mortimer

Electronic Theses and Dissertations

When people multi-task with inputs that demand attention, processing, andencoding, sensory interference is possible at almost any level. Multiple Resource Theory (MRT) suggests that such interference may be avoided by drawing from separate pools of resources available when using different sensory channels, memory processes, and even different response modes. Thus, there should be advantages in dividing tasks among different sensory channels to tap independent pools of attentional resources. For example, people are better with two tasks using the eye and ear, than when using two auditory or two visual inputs. The majority of the research on MRT involves visual to …
