Abstract
Thirty-nine men were tested on a total of six tasks; performance was measured on each task presented individually and on two complex tasks made up of three-task subsets. A factor analysis performed on the resultant data revealed a factor that showed high loadings for two different monitoring tasks for complex performance but negligible loadings for these tasks for simple performance; separate, orthogonal factors were found for the two monitoring tasks when they were performed under simple-task conditions. The monitoring measures, thus, appear to possess properties that would be expected of measures of a time-sharing ability.

The rationale of measuring operator workload in terms of auxiliary, or secondary task performance scores is reviewed and a set of standardized tasks which would be useful in obtaining more nearly comparable measures over a wide range of primary tasks are suggested.

It is concluded that experimental-correlational studies offer considerable promise in attacking complex performance but that a more extensive research program is needed.

A new technique for measuring individual differences in basic attention capabilities and the validity of these differences in predicting success in flight training were investigated and several dimensions of attention capabilities are suggested.

It was found that a man can work 12 hours per day on a 4-hours work/4-hours rest schedule for periods of at least 30 days but at a significant cost to his reserves for meeting emergencies such as sleep loss.

Nine subjects were tested on a battery of tasks involving monitoring, two-dimensional compensatory tracking, and mental arithmetic at three levels of work load, and there was a significant interaction between work load and alcohol in the case of one tracking measure.

Nine well-trained subjects were tested on a complex-performance device involving tracking, monitoring, and mental arithmetic during exposure to altitude and heat both singly and in combination, with some evidence that the two environments in combination produced a persistent effect on performance that did not dissipate with return to normal conditions.

The most important conclusions relate to the criterion problem, task taxonomies, the reliability of measures, and the role of face validity in the design of research apparatus.

It was found that order of part-task practice affects total task proficiency and observed and predicted total task scores agree better when double-level tasks are practiced before rather than after the total task.
