As far as the relationship between conscious and unconscious processes is concerned, there are two possible aspects: interactions within conscious/unconscious processes, and influences between conscious and unconscious processes. However, there is little research about the interactions between unconscious processes. Moreover, consciousness is not a dichotomous, but rather a graded, phenomenon. There can be intermediate states between completely conscious and completely unconscious states, in which information at each processing level can be accessed independently of each other. However, little research studies the top-down modulations on the information in partial awareness level. Specifically, how conscious top-down processes interact with the unconscious component of representation in partial awareness is unknown. I will demonstrate these two problems in this book.
