Development of the Criterion Task Set Performance Data Base

The initial phase of a large-scale experimental study was conducted involving the training and testing of fifty human subjects on the Criterion Task Set (Version 1.0). Testing was performed under baseline conditions and the stressors of noise and sleep loss. The resulting data base includes CTS performance data and subjective ratings obtained using the Subjective Workload Assessment Technique (SWAT) for each task, along with information on subject individual differences. This paper presents the methodology used for the data collection and analysis efforts and provides a summary of the performance and subjective assessment information. In general, no performance differences were found under the noise stress condition. Following sleep loss, response times for the central processing tasks deteriorated as did performance on the Unstable Tracking and Interval Production tasks.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

A Study of Self-Paced and Machine-Paced Inspection

A study was conducted to investigate the performance of inspectors under different conditions using computer generated visual test items. The purpose of the study was to compare performance for self-paced vs. machine-paced inspection tasks. The factors considered were searching for a single type of flaw vs. three types of flaws, the viewing time for machine-paced inspection, and the type of instruction for self-paced inspection. The results showed that performance was better when subjects searched for only one type of flaw. Performance improved with increased viewing time, but was not affected by the type of instruction. There was no difference between self-paced and machine-paced inspection provided the viewing time was sufficient. Overall, performance in self-paced inspection was better.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Factor Structure of the Criterion Task Set

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 (Trial 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.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
