ABSTRACT
Current theories of reasoning propose that reasoning is governed by two systems: conscious and unconscious. Conscious processing directs analytical thinking and results in correct responding, while unconscious processing employs heuristics that often leads to poor performance in deductive reasoning tasks. The present study uses a classic propositional task to examine the properties that distinguish conscious from unconscious reasoning. Overall, the study did not find support for dissociable reasoning systems. Instead, the findings suggest that the features exclusively attributed to each system, by dual reasoning theorists, were equally applicable to both.
