Without having read that book, I can't really respond to it. A google search did reveal this, however: http://www.psychology.sunysb.edu/ewa...dCognition.PDF
Honestly, she's creating her own theory. She's not an orthodox Freudian, nor an orthodox Cog. Psychologist. She's an eclectic, working to unite two separate fields within psychology. She isn't representative of the norm in either sub-field, and is redefining terms from either field in order to better unite them under her theory:
*****
Even she doesn't use the term Unconscious, except as 'unconscious' and only in the general sense. She has reorganized the model of the mind into the "subsymbolic, symbolic imagery, and symbolic verbal codes" and uses those terms, precisely to avoid the confusion of terms that I had mentioned in earlier posts. It isn't that she is proving Freudian theories with Cognitive methods- she is designing a theory, informed by both Cognitive and Freudian theories, that is testable with Cognitive methods.
Also, to relate to the O.P.'s question:
I think if anyone else is still in the thread, it would be a good idea to just say "ask your professor" at this point. Academic arguments can be informative for people familiar with the topic, but they don't help someone in PSY100.
