Schlegel, Betina, Schlegel, Robert E. and Gilliland, Kirby (1988): Gender Differences in Criterion Task Set Performance and Subjective Ratings. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 848-852.

“This paper summarizes gender differences in performing various elements of the Criterion Task Set. Performance data and Subjective Workload Assessment Technique ratings were analyzed for 28 men and 28 women who participated in a large-scale CTS validation study. In general, women tended to perform slightly better than men on the majority of tasks. In particular, performance by women was better on Grammatical Reasoning, Linguistic Processing, Mathematical Processing, and Memory Search. Response times on Probability Monitoring were faster for women but at the expense of a greater number of False Alarms. Men performed better only on the high level of Continuous Recall and the medium level of Unstable tracking. Women tended to give lower subjective ratings than men to those tasks with a high memory component and gave higher ratings than men to those tasks involving input/output spatial elements.”

Schlegel, Robert E., Gilliland, Kirby and Schlegel, Betina (1987): Factor Structure of the Criterion Task Set. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 389-393.

“A large-scale experimental study was conducted involving the training and testing of 123 human subjects on the Criterion Task Set (Version 1.0). Testing was performed under baseline and stressor conditions. The performance data and Subjective Workload Assessment Technique ratings for the first baseline trial (Trail 6) were analyzed using the SAS VARCLUS procedure to evaluate the structure of the CTS. Seven clusters of response time variables were identified for the nine tasks. In general, the Memory Search, Linguistic Processing and Mathematical Processing tasks were grouped in one cluster with each of the other clusters representing a single task. Five clusters were identified for the SWAT ratings with clusters differentiated along the dimensions of task difficulty and processing stage.”
