Characterizing the relationships between conscious and unconscious processes is one of the most important and long-standing goals of cognitive psychology. Renewed interest in the nature of consciousness — long considered not to be scientifically explorable —, as well as the increasingly widespread availability of functional brain imaging techniques, now offer the possibility of detailed exploration of the neural, behavioral, and computational correlates of conscious and unconscious cognition. This entry reviews some of the relevant experimental work, highlights the methodological challenges involved in establishing the extent to which cognition can occur unconsciously, and situates ongoing debates in the theoretical context provided by current thinking about consciousness.

The process-dissociation procedure has been used in a variety of experimental contexts to assess the contributions of conscious and unconscious processes to task performance. To evaluate whether motivation affects estimates of conscious and unconscious processes, participants were given incentives to follow inclusion and exclusion instructions in a perception task and a memory task. Relative to a control condition in which no performance incentives were given, the results for the perception task indicated that incentives increased the participants' ability to exclude previously presented information, which in turn both increased the estimate of conscious processes and decreased the estimate of unconscious processes. However, the results also indicated that incentives did not influence estimates of conscious or unconscious processes in the memory task. The findings suggest that the process-dissociation procedure is relatively immune to influences of motivation when used with a memory task, but that caution should be exercised when the process-dissociation is used with a perception task.

Over the past two decades, a new picture of the unconscious has emerged from a variety of disciplines that are broadly part of cognitive science. According to this picture, unconscious processes seem to be capable of doing many things that were thought to require intention, deliberation, and conscious awareness. Moreover, they accomplish these things without the conflict and drama of the psychoanalytic unconscious. These processes range from complex information processing, through goal pursuit and emotions, to cognitive control and self-regulation. This collection of 20 original chapters by leading researchers examines the unconscious from social, cognitive, and neuroscientific viewpoints, presenting some of the most important developments at the heart of this new picture of the unconscious. The New Unconscious will be an important resource on the unconscious for researchers in psychology, cognitive science and neuroscience.
