A device resembling a hand calculator provides an indicator of a subject's reaction time. An array of push-button keys has programmably varied numerals which do not correspond to an orderly presentation. A display on the device instructs that a particular sequence of numbers be touch-indicated by the subject within a certain period of time. The touched sequence and time elapsed provides an indication of the subject's reaction time which could be influenced by fatigue, ill health and drug, including alcohol, use so that the subject's effectiveness for a particular duty can be evaluated.
