Abstract:
Functional near infrared spectroscopy (fNIRS) measures of cerebral oxygenation levels were collected from participants performing difficult and easy versions of a 12 min vigilance task and for controls who merely watched the displays without a work imperative.

Abstract:
Robertson, Manly, Andrade, Baddeley, and Yiend (1997) have proposed that detection failures in vigilance tasks result from a ‘mindless’ withdrawal of attentional effort from the monitoring assignment.

Hancock, P.A., & Szalma, J.L. (2003). Vigilance and the price of freedom. Gateway: Human Systems Information Acquisition Center, 13(4), 5, 20.

Abstract:
When we have to act as a concerted group or use of convenience, such as mass transportation then individual freedoms come into conflict with collective rights.
