Chaney, Stephen and Fogarty, Gerard J. (2009) The influence of fatigue and mood on cognitive failures. In: 44th Australian Psychological Society Annual Conference (APS 2009), 30 Sep-4 Oct 2009, Darwin, Australia.
Fatigue is a variable commonly linked with cognitive failures and there is a strong body of empirical evidence substantiating the relationship. There is also evidence that the construct of fatigue can itself be defined more precisely in terms of acuteness, chronicity, and recovery time, which raises the question as to which of these dimensions of fatigue is most responsible for the relationship with cognitive failures. The present study examined this question by administering self-report measures of fatigue and cognitive failure to a group of 170 university students (143 females). A measure of mood states was also administered to test possible pathways through which fatigue variables influenced cognitive failures. Results indicated that three aspects of fatigue could be recovered through factor analysis and that scales formed from these moderately correlated factors were equally related to cognitive failures. Mediation analyses showed that a mood variable labelled as tension/confusion partially mediated the effect of fatigue on cognitive failures. These results suggest that all three aspects of fatigue can lead to adverse mood states, which in turn create conditions favourable to memory failures and attentional lapses. The demonstration of these pathways highlights ways of managing the effects of fatigue, other than through the introduction of direct fatigue counter measures.
