This neuronal activity providing us with a vague prediction is the result of corollary discharge.
When an animal performs a task, its motor system uses a forward model or an internal model of the body to predict the sensory consequences upon its completion. Electromyography, a technique to measure the movement of muscles, shows that the larynx is activated during inner speech.Īnother key finding was the activation of corollary discharge - a neural signal that helps us distinguish between self-generated sensory experience and externally produced sensory experience. This implies that inner speech should activate the same organs that external speech does. According to him, inner speech was the internalization of external speech. In the 1930s, Russian psychologist Lev Vygotsky suggested that our internal voice was heavily linked to our ability to speak aloud. So how does it work? Inner speech as internalized outer speech Inner speech has been of immense interest due to its contribution to motivational thinking and ubiquity in self-reflection. Since the emergence of psychology, there has been a strong effort to form a theory of mind. We use it to to simulate past conversations and to imagine new ones.
Inner speech allows us to narrate our own lives, as though it is an internal monologue, an entire conversation with oneself. In fact, you’re probably using it right now to read this! We use it every day, when going through shopping lists or motivating ourselves to finish that last slice of pizza. As you might have guessed, this also isn’t true. In psychological jargon, the voice you hear inside your head is called “inner speech”. Conventional wisdom tells us this is our conscience speaking, popularly depicted in the media as introspective dialogues with our angels and demons whispering in either ear.
