Chaney, Stephen (2008) The Relationships Between Fatigue, Extraversion, Mood, and Cognitive Failure. Honours thesis, University of Southern Queensland. (Unpublished)
Abstract
The main aim of this study was to examine the relationships that fatigue, extraversion, and mood form with cognitive failure. An online self-report questionnaire was developed drawing on the studies conducted by Uhlenbruch and Freeman, two previous USQ honours students. Principal Components Analysis (PCA) was used to analyse the structure of the questionnaire. The final sample (N = 170) used in hypothesis testing consisted of 27 males and 143 females. PCA, bivariate correlations, and multiple regression analysis were employed to test the aims of this study. The analysis showed that the variables were significantly related. Of interest was the fact that the trait of extraversion was negatively correlated with the error variable. This questions the popular belief that extraverts are more error prone and therefore more prone to cognitive failure. It is recommended that further research is required to understand the role extraversion plays in cognitive failure. It was found that a combination of the mood facets of tension and confusion acted as a partial mediator on fatigue with regard to error. This has important ramifications with regards to task design, and the legislation of sensible work-hours and rest periods. The secondary aim of this study was to validate the fatigue and error measurement scales, created and modified by Uhlenbruch and Freeman. Comments are offered for the use and improvement of these scales in future research. This study has highlighted some interesting relationships that may warrant consideration for inclusion into a robust error model.
