Other Thinkers

Bernard Baars has developed Global Workspace Theory[2] which bears some resemblance to stream of consciousness.

Contemporary Criticism

Susan Blackmore challenged the concept of stream of consciousness in several papers. "When I say that consciousness is an illusion I do not mean that consciousness does not exist. I mean that consciousness is not what it appears to be. If it seems to be a continuous stream of rich and detailed experiences, happening one after the other to a conscious person, this is the illusion".[3]

Literary Technique

In literature, stream of consciousness writing is a literary device which seeks to portray an individual's point of view by giving the written equivalent of the character's thought processes, either in a loose interior monologue, or in connection to his or her sensory reactions to external occurrences. Stream-of-consciousness writing is strongly associated with the modernist movement. Its introduction in the literary context, transferred from psychology, is attributed to May Sinclair[4].
