Multiple Resource Theory (Wickens, 1980) has evolved over the past three decades into a four dimensional multiple resource model. Separately, central executive functioning has been investigated. Other research has examined the relationship between risk taking and behaviour. The research in this thesis aimed to address questions arising out of these theoretical approaches. An experiment was carried out to explore the impact of executive abilities, risk perception, and risk-taking behaviour on multitasking performance. Using a novel methodology it was found that executive functioning, and the way that information is presented, were each significantly related to task performance and eye gaze in a dual-task setting. Statistically significant relationships were also found between independently developed instruments of risk perception and of risky driving behaviour. The implications of these findings for theories of attentional resources, executive functions, and mental workload are discussed.
