Holyoak and Morrison (2012) argue that 'Every fully functioning human adult shares a sense that the ability to think, to reason, is a part of their fundamental identity' (p. 1). When thinking and reasoning, humans have a propensity to base many of their judgements on prior beliefs and experiences, rather than utilising a more logical and complete approach to reasoning (see Evans and Stanovich, 2013). Although it is assumed that judgements based on beliefs and experiences are suboptimal compared to a more reflective and analytic approach, both modes of reasoning have been found to be more effective under different circumstances (see for review Dijkstra et al., 2013). When considering human reasoning, dual process theory proposes both intuitive 'Type 1' and deliberative 'Type 2' processing, which has been a dominant model within cognitive psychology for over 50 years (Evans and Frankish, 2009). Type 1, also known as intuitive, processing is autonomous and typically involves rapid, effortless, parallel, non-conscious processing that is independent of working memory and general cognitive ability. On the other hand, Type 2, also known as deliberative, processing involves slower, effortful, sequential and conscious processing and is heavily dependent on working memory and is related to individual differences in general cognitive ability (
