Abstract : An experiment was performed to evaluate the effect of early release from watch as an incentive in a visual vigilance task. The task was the detection of a slightly larger deflection of a voltmeter needle making 60 deflections per minute. The duration of the vigil was 60 minutes, in 4 consecutive 15 minute increments. Ten target signals were presented in each increment. Ten subjects (Ss) in a control group performed the task without possibility of early release from watch. Ten Ss in an experimental group performed the identical task with the incentive of being released from watch at the end of any increment in which 90% of the target signals were detected. (Author)
