ABSTRACT
Dual processing accounts of human behaviour abound in cognitive and social psychology. So many authors have appealed to dual processes in some many different ways that it has proved a complex and challenging task to draw together any coherent overview of this topic. The review is restricted to “higher” cognitive processes typically described as thinking, reasoning, decision making and social judgement, although selected work from outside of the these domains is also included where directly relevant. For example, there is some reference to work in the psychology of learning and memory, the philosophy of mind and evolutionary psychology.
