Adaptive measurement of vigilance decrement.

• Description:
  An adaptive or self-adjusting technique is described for the measurement of subject vigilance decrement with time, using a computer based monitoring task. The size of the signal stimulus, as compared to a fixed nonsignal stimulus, is mediated by the detection score of the subject to maintain a constant detection rate. Data indicate that to maintain a fixed detection criterion over a 48 minute vigil, the separation distance of a pair of dots presented simultaneously behaves in a manner consistent with the usual measures of vigilance decrement. Adaptive techniques are cited as offering promise as vigilance research tools and for practical work applications where monitors can be trained to some preset criterion by adjusting the parameters of a signal.
