We present an account of two influential approaches to the unconscious; those of Freud and of cognitive science. It is argued that although Freud's ideas require updating in some respects, in other ways many of them have stood the test of time. We describe the similarities and differences between the two approaches and the attention each pays to innate cognitive and emotional competencies. Finally, we provide a contemporary cognitive account of the unconscious that attempts to combine the best both approaches within an information-processing framework.
