VIGILANCE FOR CUTANEOUS AND AUDITORY STIMULI AS A FUNCTION OF INTERSIGNAL INTERVAL AND SIGNAL STRENGTH

Abstract

Vigilance for infrequent auditory or electrical cutaneous stimuli at both weak and moderate intensities was investigated. Detection probability was very high for moderate intensity signals and weak auditory stimuli. Errors significantly increased with time on task for faint cutaneous signals. Increase of the intersignal interval significantly increased the number of errors. An explanation of the results is suggested in terms of greater habituation for weak or relatively infrequent signals.
