Activation and Sustained Attention: A Pupillometric Study of an Auditory Vigilance Task.

reportActive / Technical Report | Accession Number: ADA050040 | Open PDF

Abstract:

Using a classical auditory vigilance task, the relations between pupillometric indices of phasic central nervous system increases in activation and sustained attention were investigated. The amplitude of the task-invoked pupillary response declined as a function of time in task at a rate paralleling the performance decrement. These findings are discussed in the context of an activation theory of attentional processes. Author
