In its simplest form, the scenario above is an example of what psychologists call dual-process theory. The term "dual-process" refers to the idea that some behaviors and cognitive processes (such as decision-making) are the products of two distinct cognitive processes, often called System 1 and System 2 (Kaufmann, 2011:443-445).
