Now you hear me, now you don't: eyelid closures as an indicator of auditory task disengagement.

ABSTRACT:

Study objectives

Eyelid closures in fatigued individuals signify task disengagement in attention-demanding visual tasks. Here, we studied how varying degrees of eyelid closure predict responses to auditory stimuli depending on whether a participant is well rested or sleep deprived. We also examined time-on-task effects and how more and less vulnerable individuals differed in frequency of eye closures and lapses.

Design

Six repetitions of an auditory vigilance task were performed in each of two sessions: rested wakefulness (RW) and total sleep deprivation (TSD) (order counterbalanced).

Setting

Sleep laboratory.

Participants

Nineteen healthy young adults (mean age: 22 ± 2.8 y; 11 males).

Intervention

Approximately 24 h of TSD.
