Abstract
THE time taken by human beings to react to one of a number of possible signals increases with the number of alternatives involved. The effects of jointly varying stimulus and response uncertainty have been long known and adequately discussed1,2. In the present investigation these were varied independently, by using situations where the same response was required for a number of stimuli. The number of responses, and the ratio of response/stimuli were varied.
