This study is the first in a program to develop a battery of Performance Evaluation Tests for Environmental Research PETER. Nineteen volunteer subjects were tested daily for 3 weeks on a complex task requiring the operator to keep simultaneous track of several things with changing states. Average daily performances are reported as well as reliabilities of three main types 1 internal consistency of the test 2 sensitivity-the ability to differentiate subjects, and 3 stability-consistency of measurement over repeated sessions. The results showed that, on this task, learning was accomplished quickly, and performance stayed level for 3 weeks. AN
