The Impact of VDU Tasks and Continuous Feedback on Arousal and Well-Being: Preliminary Findings

摘要

In the present study the impact of VDU taks differing in mental load and feedback were investigated in relation to physiological arousal and well-being. Healthy students (N= 37, age 18-30 years) were included in the study. The subjects were divided in two groups starting with either a standard/feedback version of the Dual task (high task load), or a standard/feedback version of the Stroop task (moderate task load). Presently, we report the preliminary outcomes of this study. Overall, well-being gradually decreased and arousal increased while performing the consecutive VDU tasks. Furthermore, in HRA, mental effort, and subjective arousal a differentiation could be made between the two groups. When subjects commenced with a task with a high mental load (dual task), it had a higher impact on arousal and well-being as a function of time. Feedback did not appear to play an important role on a subjective and physical level.
