Abstract
The primary goal of the study was to construct a computerised information-processing test battery to measure choice
reaction time for up to and including six bits of information, to measure discrimination reaction time with regard
to colour patterns and form patterns, to measure rate of information processing with regard to perceptual stimuli and conceptual reasoning, and to develop a suitable scoring system for the respective tests. The battery of tests was applied to 58 pilots. In order to develop an appropriate scoring system for each of the tests, the various scores (trials)were intercorrelated, and where necessary, subjected to factor analysis.
