Brain versus mind: The word brain tends to be used when people talk about anatomical structures or circuitry in the brain. The term mind tends to be used to refer to the subjective cognitive states a brain creates. For example, the prefrontal cortex is an anatomical part of the brain, but attention is a cognitive âstate of mindâ produced by activity in the brain.
Generally, we use these terms interchangeably. We consider ânonconscious processes in the brainâ to be equivalent to âthe nonconscious mind.â

Unconscious, subconscious, preconscious, and nonconscious: There is a lot of intellectual baggage associated with all the terms that can be used to refer to the ânot-consciousâ processes in the brain. Unconscious has some bad connotations, in terms of both the Freudian unconscious and the association with anesthetized states. Subconscious, in turn, carries a âsecondaryâ or âsubsidiaryâ connotation, as if itâs something below and, therefore, less than the conscious. A similar term is preconscious, which often would be perfectly appropriate, but it implies that conscious always follows preconscious, and this isnât always true. Given all these issues, we use the more neutral term nonconscious in this book. Using this term has the benefit of referring neutrally to âeverything other than consciousâ; plus, itâs the term thatâs becoming the standard in the academic literature.
