TONGUE-SHOW
Don't bother me now! --"Recent
research at the University of Western Australia identified the [slightly]
protruded tongue as a particularly effective cue for this message" (Burgoon et
al. 1989:411).
Facial
expression. 1. A momentary protrusion of the
tongue between the lips. 2. A gesture of the tongue found in
gorillas and other primates, in children, and in all ethnic groups studied.
Usage: The tongue-show is a universal mood sign of unspoken
disagreement, disbelief, disliking, displeasure, or uncertainty. It may modify, counteract, or contradict a
verbal remark. Following the statement, "Yes, I agree," e.g., a protruded tongue
may suggest, "I don't agree." Tongue-shows can reveal misleading, ambiguous, or
uncertain areas in dialogue, public statements, and oral testimony, and thus may
signal probing points (i.e., unresolved verbal issues to be
further analyzed and explored).
Culture. In Tibet and southern
China, a brief tongue-tip show is used to show, "I didn't mean it"
(Morris 1994:224).
Pediatrics. Infants ranging in age from 0.7 to 72 hours old can
imitate adult displays of tongue protrusion (Meltzoff and Moore 1983).
RESEARCH REPORTS: 1. The
tongue-show has been studied in both gorillas and human beings as a
negative sign of aversiveness and social stress (Smith et al.
1974). A gorilla pushed from its favorite sitting place, e.g., or a man entering
a roomful of strangers, will unwittingly show the tongue in
"displeasure." 2. Staring, striking, or scolding another
primate may release a tongue protrusion, which may be a fragment of the emotion
cue for disgust (Smith et al. 1974). 3.
Tongue between lips is a defensive sign children use when approaching
strange adults (Stern and Bender 1974).
E-Commentary I: "About body
language acts, in police interrogations I have many times observed the
tongue-showing cue just before the defendant would confess." --Marco Pacori

E-Commentary II: "I was trying
to discover what a tongue meant if it was curled, poked determinedly towards the
lips so an observer could see a tube or hollow. The mouth being rounded. This
was at the same time as the person concerned was saying something that I felt
was 'beaten you at this one' or 'I know best'. It seemed to be a gargoyle facial
expression. Very worrying. Should I be concerned? Last time he did that was
shortly (days) before beating me up. I am not expecting diagnosis nor counseling
but seek data on such an event in order to come to my own conclusion. Do you
have any reference or studies that I can view?" --Gillian (5/25/01 11:19:17 AM

E-Commentary III: "During my
stay in Thailand on the island of Koh Samui, I bought many handmade articles.
There, when one wants to buy something one bargains over the price. So I adapted
myself to that custom. Though many behaviors are different from ours [Marco
Pacori is Italian], nonverbal behavior stays the same. On one occasion, I
haggled about the price of a pair of pants. I asked the merchant how much, and
she quoted an outrageous price. So I began to bargain. I proposed a very low
price and she retorted with a very high price still. So, we went on negotiating.
At a given time I proposed a certain sum, and she made a curious behavior. She
looked away from me, her eyes appeared vacant, and she made a tongue protrusion
(her tongue appeared for a moment quickly out of her mouth). I have seen this
act in police interrogations moments before the suspect was going to yield [see
above, E-Commentary I].
Remembering the meaning of this observation, I put 'psychological' pressure on
her and she agreed to my price." --Marco Pacori (9/6/01 2:49:11 AM Pacific
Daylight Time)
Neuro-notes. 1. Subcortical: The tongue-show reflects
negative emotions of the amygdala acting through brain-stem paleocircuits of the hypoglossal nerve
(cranial XII). Stimulation of the amygdala can produce unwitting tongue
movements associated with eating and the sense of smell (Guyton 1996:758-59).
2. Cortical: That we often tongue-show while performing tasks
which involve precise manual dexterity, such as, e.g., while threading a needle,
may reflect the neural linkage between human tool-making and speech (see WORD,
Neuro-notes I).

TONGUE-SHOW & PRECISION GRIP
Linguistic dimension. The tongue-show is also likely related to human speech, according to research published in 2019 in Frontiers in Psychology. Neurocircuits for hand gestures, speech (e.g., tongue movements), and tool-making (e.g., the precision grip) interlink.

"Why do we stick out our tongues when we're concentrating?"
By Donavyn Coffey published December 27, 2021, Live Science
"One theory for why this happens is called motor overflow. Neuroimaging reveals that the region of the brain devoted to language (located in the inferior frontal gyrus) is highly overlapping with neural networks devoted to dexterity and tool use, according to a 2019 study published in Frontiers in Psychology. Motor overflow suggests that neurons firing in the dexterity region are so activated that they overflow into neighboring neural tissue (which happens to direct the mouth). Therefore, when you're deeply focused on a fine-motor task, the effect "spills over" into the language region, causing you to engage your mouth and tongue."
