Operant conditioning techniques were applied to the study of how human looking behavior is controlled by what is seen. In a standard vigilance setting, gaze at three illuminable volt meters was monitored by a Mackworth television eye camera with automatic recording capability. Gaze at a given meter produce illumination of the meter, and signals deflections of the needle on the meter were programmed as intermettent consequences of this response. Looking behavior was thus placed under the control of concurrent variable ratio, DRL and fixed interval schedules in normal adult volunteers. The effects of 24-hour sleep deprivation on this schedule control were studied in a single subject. The results showed that deterioration in signal detection under conditions of fatigue was a reflection of a decreased rate of observing responses, rather than a decreased efficiency of signal detection per observing response. It was concluded that concurrent schedule control is an effective experimental tool for studying the effects of display and physiological variables on human eye movement behavior. Author
