The Workload Curve: Subjective Mental Workload

摘要

Objective: In this paper I begin looking for evidence of a subjective workload curve.n Background: Results from subjective mental workload assessments are often interpreted linearly. However, I hypothesized that ratings of subjective mental workload increase nonlinearly with unitary increases in working memory load.n Method: Two studies were conducted. In the first, the participant provided ratings of the mental difficulty of a series of digit span recall tasks. In the second study, particip
