The secret of the inner voice that we hear in our head without saying a word is revealed.
The inner voice is a poorly explored phenomenon. Mark Scott of the University of British Columbia decided to figure it out. He found evidence that our inner speech is greatly influenced by the external stimuli that we produce ourselves. For example, when we are talking we create an internal copy of our voice in parallel with the sound that we hear.
This copy, as suggested by Scott, is the intra prediction of our own voice. These findings point to the fact that internal speech involves the system for processing external speech, which may help in diagnosing certain pathological conditions.
The researcher says this work is important because the theory of inner speech is closely related to the theories of auditory hallucinations as, for example, in schizophrenia.
