The logical intuition model stipulates that effortful reasoning processes can become intuitive with increased practice and experience. However, this assumption has not previously been tested, nor integrated with the model's key elements: conflict and working memory engagement. In six studies within four papers, this thesis addresses this gap by examining conflict, a form of cognitive uncertainty, and working memory engagement as determined by experience. By examining the relationship between mathematical experience and CRT performance, we first demonstrate that, as domain-specific experience increases, working memory dependence decreases. This transition is then used to examine the relationship between conflict and working memory engagement. Paper 1 examines the effect of a secondary task on CRT performance across different levels of mathematical experience, demonstrating that working memory dependence decreases as experience increases. In Paper 2, we examine the relationship between explicit conflict and performance, and between explicit conflict and working memory engagement; finding that explicit conflict becomes a stronger predictor of performance as experience increased and that explicit conflict predicts working memory engagement. In Paper 3, using confidence ratings and novel eye-tracking measures, we demonstrate that participants register explicit and implicit conflict when giving incorrect responses on the CRT. In Paper 4, we find that implicit and explicit conflict factors independently predict working memory engagement. These papers comprise the first empirical assessment of a core assumption in dual process reasoning theories: that reasoning processes can transition from effortful to automatic. In examining this transition, a novel approach is used to explore key elements of the logical intuition model of reasoning. Overall, findings support the logical intuition model, but they also introduce additional qualifications.Mode of access: Internet.1 online resource (vi, 293 pages
