| Tiivistelmä: | Subjective workload assessment is one of the most frequently used tools for system evaluation. However, little is known about which factors contribute to the sensitivity, validity, and reliability of subjective workload ratings. One major classification of subjective workload assessment tools is based on relative judgments of the workload of different task conditions. The present research evaluated different approaches to relative subjective workload assessment in terms of their sensitivity to demand manipulations, concurrent validity with performance, and test-retest reliability. |
