The sleep and wake drives : exploring the genetic and psychophysiological aspects of sleepiness, motivation, and performance

Watling, Christopher N. (2016) The sleep and wake drives : exploring the genetic and psychophysiological aspects of sleepiness, motivation, and performance. PhD thesis, Queensland University of Technology.


This research program examined the factors of motivation and genetic variations for their effects on sleepiness and performance. The results suggest that certain genetic variations were found to influence aspects of physiological and subjective sleepiness as well as performance outcomes. Motivation had no effect on performance when partially sleep deprived, but motivation improved task performance on a low-order cognitive task when fully rested. The results suggest sleepiness is resistant to motivation to improve performance. As such, drivers who continue to drive while sleepy by applying extra effort to the task of driving are engaging in a risky driving behaviour.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
