Inner Dialogue

Intrapersonal communication is language use or thought internal to the communicator. It can be useful to envision intrapersonal communication occurring in the mind of the individual in a model which contains a sender, receiver, and feedback loop.

Definitions
Although successful communication is generally defined as being between two or more individuals, issues concerning the useful nature of intrapersonal communication made some argue that this definition is too narrow.

In Communication: The Social Matrix of Psychiatry, Jurgen Ruesch and Gregory Bateson argue that intrapersonal communication is indeed a special case of interpersonal communication, as "dialogue is the foundation for all discourse."

Intrapersonal communication can encompass:


 * Speaking aloud (talking to oneself), reading aloud, repeating what one hears; the additional activities of speaking and hearing (in the third case of hearing again) what one thinks, reads or hears may increase concentration and retention. This is considered normal, and the extent to which it occurs varies from person to person. The time when there should be concern is when talking to oneself occurs outside of socially acceptable situations.
 * Internal monologue, the semi-constant internal monologue one has with oneself at a conscious or semi-conscious level.
 * Writing (by hand, or with a word processor, etc.) one's thoughts or observations: the additional activities, on top of thinking, of writing and reading back may again increase self-understanding ("How do I know what I mean until I see what I say?") and concentration. It aids ordering one's thoughts; in addition it produces a record that can be used later again. Copying text to aid memorizing also falls in this category.
 * Writing need not be limited to words in a natural or even formal language. Doodling also falls into this category. Children may be communicating intrapersonally when they doodle and adults sometimes argue that they do...
 * Making gestures while thinking: the additional activity, on top of thinking, of body motions, may again increase concentration, assist in problem solving, and assist memory.
 * Again, routinely observed in children, the equivalent of doodling without writing. Everyday images are transformed by gestures that form a new lens through which to view the images.
 * Sense-making (see Karl Weick) e.g. interpreting maps, texts, signs, and symbols
 * Interpreting non-verbal communication (see Albert Mehrabian) e.g. gestures, eye contact
 * Communication between body parts; e.g. "My stomach is telling me it's time for lunch."

Mechanisms
Our ability to talk to ourselves and think in words is a major part of the human experience of consciousness. From a young age, individuals are encouraged by society to introspect carefully, but also to communicate the results of that introspection. Simon Jones and Charles Fernyhough cite research suggesting that our ability to talk to ourselves is very similar to regular speech. This theory originates with the developmental psychologist Lev Vygotsky, who observed that children will often narrate their actions out loud before eventually replacing the habit with the adult equivalent: sub-vocal articulation. During sub-vocal articulation, no sound is made but the mouth still moves. Eventually, adults may learn to inhibit their mouth movements, although they still experience the words as "inner speech".

Jones and Fernyhough cite other evidence for this hypothesis that inner speech is essentially like any other action. They mention that schizophrenics suffering auditory verbal hallucinations (AVH) need only open their mouths in order to disrupt the voices in their heads. To try and explain more about how inner speech works, but also what goes wrong with AVH patients, Jones and Fernyhough adapt what is known as the "forward model" of motor control, which uses the idea of "efferent copies".

In a forward model of motor control, the mind generates movement unconsciously. While information is sent to the necessary body parts, the mind basically faxes a copy of that same information to other areas of the brain. This "efferent" copy could then be used to make predictions about upcoming movements. If the actual sensations match predictions, we experience the feeling of agency. If there is a mismatch between the body and its predicted position, perhaps due to obstructions or other cognitive disruption, no feeling of agency occurs. Jones and Fernyhough believe that the forward model might explain AVH and inner speech. Perhaps, if inner speech is a normal action, then the malfunction in schizophrenic patients is not the fact that actions (i.e. voices) are occurring at all. Instead, it may be that they are experiencing normal, inner speech, but the generation of the predictive efferent copy is malfunctioning. Without an efferent copy, motor commands are judged as alien (i.e. one does not feel like they caused the action). This could also explain why an open mouth stops the experience of alien voices: When the patient opens their mouth, the inner speech motor movements are not planned in the first place.

Evolved to avoid silence
Joseph Jordania suggested that talking to oneself can be used to avoid silence. According to him, the ancestors of humans, like many other social animals, used contact calls to maintain constant contact with the members of the group, and a signal of danger was communicated through becoming silent and freezing. Because of the human evolutionary history, prolonged silence is perceived as a sign of danger and triggers a feeling of uneasiness and fear. According to Jordania, talking to oneself is only one of the ways to fill in prolonged gaps of silence in humans. Other ways of filling in prolonged silence are humming, whistling, finger drumming, or having TV, radio or music on all the time.

Criticism of the concept
In 1992, a chapter in Communication Yearbook #15, argued that "intrapersonal communication" is a flawed concept. The chapter first itemized the various definitions. Intrapersonal communication, it appears, arises from a series of logical and linguistic improprieties. The descriptor itself, 'intrapersonal communication' is ambiguous: many definitions appear to be circular since they borrow, apply and thereby distort conceptual features (e.g., sender, receiver, message, dialogue) drawn from normal inter-person communication; unknown entities or person-parts allegedly conduct the 'intrapersonal' exchange; in many cases, a very private language is posited which, upon analysis, turns out to be totally inaccessible and ultimately indefensible. In general, intrapersonal communication appears to arise from the tendency to interpret the inner mental processes that precede and accompany our communicative behaviors as if they too were yet another kind of communication process. The overall point is that this reconstruction of our inner mental processes in the language and idioms of everyday public conversation is highly questionable, tenuous at best.

Other viewpoints
Dr. Sian Beilock, cognitive psychology professor at the University of Chicago, presents several techniques in her book Choke, that could offer help to anyone facing a challenging situation and struggling with mental chatter. It has been widely accepted that speaking in front of a crowd causes people considerable stress. Dr. Beilock suggests that practicing in front of family or friends does not help overcome this fear. She states that these so-called "friendly faces" can cause the person to become more self-conscious which can lead to the possibility of further choking. The elevated motivation to please parents or friends is what she theorizes causes brain functions to freeze. Since self talk is a form of self-regulation, parents or instructors could use this technique to help focus a young student's inner dialog towards a process goal instead of an outcome based goal. When applied in an educational psychology classroom scenario, teachers can instruct students to focus on presentation material ignoring consequences, expectations, and/or the attempt to impress instructors or classmates.
