Stream of consciousness refers to the flow of thoughts in the conscious mind. The full range of thoughts that one can be aware of can form the content of this stream, not just verbal thoughts. Commonly used experimental techniques, including self-reporting, gives easier access to verbal thoughts than to thoughts more closely connected to senses other than hearing and activities other than speaking and writing.
Also 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.
