Abstract : A performance test battery consisting of three tasks (memory/visual search, serial arithmetic, and column addition) was developed for use on an Apple II microcomputer. For each task, several workload parameters were varied via a menu. In three separate experiments, performance variables (response latency and error rate) were found to be sensitive to changes in workload. THe test battery is an easy method of varying workload through the use of a controlled laboratory task. Future research measuring subjective opinions and evoked potentials is planned using this battery of tasks. Keywords: Mental workload, Mental arithmetic, Assessment battery, Visual search, Memory search.
