The primary purpose of the study was to determine the nature of the practice curves for various types of measurement postulated as fatigue detectors. At the same time it was thought advisable to design the experiment in such a way as to secure some information on the effect of ingestion of tea on certain psychomotor performance tasks at different practice levels as well as throughout the entire series of practices. In other words this study was set up to select some promising techniques for measuring work decrement over a period of several hours continuous performance and to establish the degree of learning to be expected from successive practices. This was necessary to facilitate the selection of the most efficient and practical fatigue detectors available which might be used in a major study on the effect of tea pauses on continued performance of a complex nature such as driving an automobile. The data were also important for establishing correction constants for different stages of learning.
