Information theory concepts are currently being applied to obtain a quantitative measure of work difficulty or complexity. This paper uses Information Theory to investigate the relationship between information input and operator response time. To investigate this relationship, twelve male subjects were tested for reaction time. Stimuli were any possible patterns of eight lights. Responses were corresponding patterns of stimultaneous key depressions in an eight-key keyboard one key for each finger. The conclusion drawn from these experiments was that there seems to be a linear relationship between information input log2 N, where N is the number of equally likely alternatives and operator reaction time for an unlearned task.
