Wittgenstein, mimicry and congenital facial paralysis 

Abstract

Mimicry refers to the tendency to adopt the behavioral expressions of interaction partners. According to Wittgenstein, mimicry typically occurs outside of conscious awareness, and without any intent to mimic or imitate. Further, he suggests a bi-directional relationship between mimicry on the one hand, and rapport, affiliation on the other. That is, the ability to imitate and mimic what one perceives in the expression of another person creates affiliation, and affiliation can be expressed through mimicry. We argue that mimicry plays an important part in our form of life. Mimicry increases affiliation, which serves to promote relationships with others.

The congenital absence of facial expression and the inability to imitate facially the expressions of other persons may result in profound changes in the way a person is perceived by others and in a subsequent loss of affiliation. These experiences reveal not merely the importance of perceiving feelings and the capacity for imitating others for the maintenance of human relationships, but also the extent to which adults with a condition such as Möbius Syndrome may have difficulty in engaging in a shared form of life with others. These limitations are partial rather than absolute, however, and people with Möbius may yet maintain social coordination through their other channels of expression; through prosody of voice, gesture, clothes, enriched vocabulary, and so on.

1 Introduction

In his late writings, Wittgenstein notes that humans have a tendency to mimic the observable behavior of others (Wittgenstein, 1958; 1980a; 1980b). He writes: 

‘I see that the child wants to touch the dog, but doesn’t dare’. How can I see that?  – Is this description of what is seen on the same level as a description of moving shapes and colors? Is an interpretation in question? Well, remember that you may also mimic a human being who would like to touch something but doesn’t dare. (Wittgenstein, 1980a, §1066) 

If someone sees a smile and does not know it for a smile, does not understand it as such, does he see it differently from someone else who understands it? – He mimics it differently, for instance. (Wittgenstein, 1958, p. 198) 

We can discern three claims in the quoted passages. First, we directly perceive thoughts and feelings in the expressions of other people, and not by way of inference. Second, we have a tendency to mimic others because perception automatically elicits corresponding behavior. Thirdly, behavioral mimicry is relevant for understanding what an expression means. If an individual could not do this, he may not understand what is expressed. Let’s now examine these claims. 

2 Social perception

What can we perceive? According to Wittgenstein, we perceive what we may call observables. This grouping involves behavior that we can literally perceive. We can see someone wave, scratch her head and wiggle his foot. Also, we hear people speak. Not only do we listen to the contents of speech, we also perceive other variables such as accents or tone of voice. Finally, we can perceive various facial expressions. We see people smile or frown, for example, and we apprehend the person’s feelings as that person’s feelings, through what we see in the face. Wittgenstein writes:

‘We see emotion.’ – As opposed to what? – We do not see facial contortions and make the inference that he is feeling joy, grief, boredom. We describe a face immediately as sad, radiant, bored, even when we are unable to give any other description of the features. – Grief, one would like to say, is personified in the face. This is essential to what we call ‘emotion’. (Wittgenstein, 1980b, §570) 

Consciousness in another’s face. Look into someone else’s face, and see the consciousness in it, and a particular shade of consciousness. You see on it, in it, joy, indifference, interest, excitement, torpor, and so on. The light in other people’s faces. Do you look into yourself in order to recognize the fury in his face? It is there as clearly as in your own breast. (Wittgenstein, 1967, §220) 

We might also say: ‘It is there as clearly as in your own face’. The substitution is natural because it captures how mimicry is directly connected to understanding behavior as perceived in someone else. We perceive not merely because we need it to analyze and comprehend the expressions of interaction partners, but because we need it to behave. Perception is for doing. If the behavior of others communicates information, our perceptions of others’ behavior may then be used to guide our own behavior. Wittgenstein’s notion of an express connection between perception and behavior offers an alternative to the view of perception as functioning primarily to give us information about the external environment. He appears to be claiming that understanding and comprehension of the behavior of others are only means by which we act effectively, and do not constitute the basic function of perception. Wittgenstein seems to be hinting at this in the following excerpt: 

It comes to this: only of a living human being and what resembles (behaves like) a living human being can one say: it has sensations; it sees; is blind; is deaf; is conscious or unconscious. (Wittgenstein, 1958, §281) 

Social perception leads directly to social behavior. The tendency to mimic reveals an uninterrupted link between what we see and the behavior mimicry that corresponds to it. As a result, we often do what we see others doing. This suggests that mimicry is an automatic reaction to the expressions of interaction partners.

As mimicry is the direct consequence of perception, we do not require additional mental processes or private experiences to engage in it. No introspection is required, nor a conscious decision. We just do it. In facial mimicry, for example, we do not typically compare the facial expressions we mimic with the sensations of our facial musculature and decide that they match. Nor do we need to monitor or check the precise disposition of our features in such circumstances. Think how we engage in facial mimicry without seeing one’s own face in a mirror (Wittgenstein, 1958, §285). The difference between a friendly smile and a cruel smile, a wry smile or an ironic smile may be no more than a minute difference (a thousandth of an inch) in the orientation of the facial features, but we perceive it automatically, which also means that we can mimic these expressions without awareness, intent, or conscious control. The behavioral mimicry that corresponds to what we see is not the result of subjecting subtle degrees of behavioral difference to mental calculations. There is no act or process of ascertaining facial dimensions prior to facial mimicry of an expression. According to Wittgenstein, we simply react differently to such different facial expressions, and we would not explain our different descriptions of facial expressions or our mimicry of them by reference to measurement (Wittgenstein, 1958, §285). Just consider what it is like to respond to a broadly smiling infant, for here is an instance of the immediacy of what is called ‘natural reactions of persons to persons’ (Hamlyn, 1974). Wittgenstein writes: 

One may also say: ‘He made this face’ or ‘His face altered like this’, imitating it – and again one can’t describe it in any other way’. (Wittgenstein, 1980a, §920)

In sum, Wittgenstein acknowledges that observers mimic behavioral displays. Adaptive perception is in the service of functional behavioral responding to the environment, and mimicry is an automatic response of persons to persons. 

3 The absence of mimicry and counter-mimicry          

Our next task is to fill out the basic account described above. For it seems that mimicry may not always occur. In other cases, counter-mimicry may result. If correct, the absence of mimicry and counter-mimicry suggests that the tendency to mimic is somewhat less automatic and reflex-like than otherwise thought. In fact, Wittgenstein anticipated these possibilities. He imagines a face incapable of making gradual and subtle movements, and which had a limited number of facial expressions. When it altered, it would snap straight from one expression to another. He asks: ‘Would this fixed smile really be a smile? I might not be able to react as I do to a smile. Maybe it would not make me smile myself’ (Wittgenstein, 1980b, §614). This suggests that facial mimicry and mimicry in general is not obligatory, and can be inhibited. Wittgenstein may support a conception of facial mimicry as ‘default social behavior': we automatically mimic, as long as other considerations do not have a reason to intervene. For example, ‘a person who had seen only one facial expression couldn’t have the concept ‘facial expression’. ‘Facial expression’ exists only within a play of features’ (Wittgenstein, 1992, §766). This means that a person who had only seen ‘happy’ faces could not mimic them as happy.

Wittgenstein also thinks that the nature of a judgment task may influence the expression or absence of facial mimicry. He hints that facial reactions to facial expressions may be either affective or cognitive. If we were to meet people who randomly mixed up posed and spontaneous emotional facial expressions, it is conceivable that ‘we should not know where we were within them’ (Wittgenstein, 1992, §201). And, if we had to decide whether an emotional facial expression was posed or spontaneous, a cognitive response such as ‘I have no idea what is going on inside of them’ may well inhibit facial mimicry. By contrast, an affective judgment regarding what we see will likely activate automatic facial mimicry. The suggested reason is that mimicry involves an affective response to what we perceive. Imitating the expressions of others indicates affiliation and personal relatedness towards the embodied individual whose expressions they are. Does Wittgenstein therefore imply that facial mimicry is related to affiliation? That is, does facial mimicry lead to feelings of closeness and rapport, and make social interactions smoother and more harmonious? We answer in the affirmative, and propose below that Wittgenstein holds that mimicking the behavior of others ‘bonds’ people together.

4 Mimicry, rapport and interpersonal closeness

The sense of psychological connection members of a form of life feel allows them to live in harmony and accomplish shared practices and activities. Behaviors that facilitate and maintain bonds between life-members are therefore extremely important. Individuals who tend to mimic their peers likely experience this psychological connection, and therefore would be likely to continue to engage in a shared form of life with the others.

The following excerpt suggests that Wittgenstein sees facial mimicry as a means to communicate rapport with another. He writes: ‘for a child to perceive a smile as a smile is for the child to be drawn into a quality of relatedness to the smiling person, such that the child is inclined to smile…’ (Wittgenstein, 1980a, §766) In facial mimicry, what is expressed through the other’s face becomes a component of the mimicking observer’s own affective state. This may explain why smiles are not perceived as mere facial contortions: in mimicking the expressions of another, we apply a kind of perception that means we have an affective response to what we see. Indeed, a person could not acquire the concept of ‘smile’ unless he could be affected by and engaged with a smiling person. Wittgenstein writes: ‘My relation to the appearance [of facial expressions] here is part of my concept’ (Wittgenstein, 1980b, §617). Hamlyn (1974) endorses this theme in claiming that we could not know what a person is, unless we felt a sense of psychological connection with others.

Imagine individuals engaged in a task with a confederate who either mimicked their facial expressions or had mechanical, fixed facial displays that ‘would snap straight from one to another’ (Wittgenstein, 1980b, §614). We may well assume that those who were not mimicked feeling alienated and thinking ‘I have no idea what is going on inside of him’, or even ‘I am not sure he likes me’. By contrast, individuals who were mimicked will likely see the interaction as having been smooth and harmonious and they may even like the confederate more. It appears therefore that Wittgenstein may be credited with the view of mimicry as a manifestation of personal relatedness towards the subject of the feelings.

As we will see in the next section, situational factors that create a desire to affiliate such as the condition of congenital facial paralysis may stimulate more mimicry. Individual differences in the desire to affiliate may also influence behavioral mimicry and contribute to rapport and interpersonal relatedness. For example, empathic individuals who are able to perceive and adopt the perspectives of others as perspectives, both different from and coordinated with one’s own, may mimic people more than people low in empathy. The ability to take the perspectives of others activates mimicry, suggesting that individuals who are able to affiliate with another person or groups of persons because of their ability to assimilate the state of someone else also can employ mimicry behavior. A person unable to mimic the facial displays of others would likely have a reduced capacity to share or otherwise coordinate perspectives with others.

Support for these claims comes from a paper by Hampshire (1976) who develops Wittgenstein’s ideas. He notes that ‘the primitive faculty of imitation’ creates social coordination through affiliation between interaction partners, or as he expresses it, ‘a necessary background to the communication of feeling’ (Hampshire, 1976, p.73). He goes on: 

In direct dealings with men, outside the context of fiction, we perceive, and react to, the physiognomy of persons almost as immediately as to the full behavior of which the facial expression is the residue…Because of the connecting arch of expression, we cannot truthfully say, as many philosophers have implied, that we perceive only the behavior of others, if behavior is interpreted as that which is described in terms of effective actions performed and in socially recognized routines. We perceive also that kind of residual, shadow behavior which constitutes an expression. And we can show that we have perceived it by adopting the same expression in imitation, without trying to reproduce, item by item, the physical features of the face or posture of another (Hampshire, 1976, 78-79).

We speculate that rapport and interpersonal closeness may stimulate a person to mimic more. This is a possibility that would allow members to be successful with the interactions. An individual mimics to create rapport and be included in the form of life. The ‘quality of relatedness’ that develops between life members then extends the circle, as it causes life members to continue to mimic each other, which creates more rapport. 

5 Mimicry and congenital facial paralysis

We have been proposing that Wittgenstein’s remarks reviewed above are consistent with the claim that one reason people mimic others is that this mimicry has some adaptive value. To the extent that an individual shares practices and activities with other people, and engages in behavior that facilitates this goal, that person will be included in the form of life. The inability to mimic the expressions of others caused by the loss of facial expression may therefore result in a partial failure to engage in a form of life shared with others. The flaccid facial skin and expressionless face characterizing Möbius Syndrome, a condition of congenital facial paralysis, makes an individual appear dissimilar to interaction partners and therefore may diminish the psychological connection with others, especially unknown others (Briegel, 2003). These limitations are partial rather than absolute, however, and people with Möbius may yet maintain social coordination through their other channels of expression; through prosody of voice, gesture, enriched vocabulary, and so on. 

5.1 Möbius Syndrome and ‘private’ language 

How do words refer to sensations? Here is one possibility: words are connected with the primitive, the natural, expressions of the sensation and used in their place. (Wittgenstein, 1958, §244) 

But suppose I didn’t have any natural expression for the sensation, but only had the sensation? And now I simply associate names with sensations and use these names in descriptions. (Wittgenstein, 1958, §256)

In his remarks on the possibility of a ‘private’ language, Wittgenstein imagines a language in which the sensation-words are not connected with sensations as partial substitutes for natural expressions of sensations, as they are in our ordinary languages (Wittgenstein, 1958, §244). Experiences here are conceived to lack any manifestation in behavior, and so the names of experiences are not linked to displays such as facial expressions or behavioral mimicry. In the absence of a connection with facial-behavior, what links name and experience? Cole (2000) describes a woman with congenital facial paralysis who, like the ‘private’ linguist just described, is unable to link words with experiences as substitutes for facial expressions. In her job as a care-worker she had experienced some prejudice from elderly patients, but she successfully surmounted it. He writes: 

Her use of body language and intonation in speech had essentially overcome these problems. When she had taken her wedding photographs round to friends they had teased her for not smiling. She had to tell them that she never smiled – her friends had not noticed her lack of facial movement in smiling because she communicated her happiness through other channels. (Cole, 2000, p.253)

Some people with congenital facial paralysis may overcome their loss by linking words and experiences with other expressive-behaviors. These other expressions in turn may be used as behavioral mimicry and could succeed in creating an interpersonal connection with others (Cole, 2001). Indeed, situations where there is a desire to affiliate activate the tendency to mimic the behavior of interaction partners (Lakin & Chartrand, 2003). Consequently, we would expect to see behavioral mimicry in an individual with congenital facial paralysis who is stimulated by the condition to affiliate with others.

There may be evidence showing that the ability to produce facial expressions is not a necessary prerequisite of their recognition. In one study of facial expression recognition by three people with congenital facial paralysis (Calder, A. J. et al., 2000), participants were asked to identify the emotion displayed in 10 examples of facial expressions associated with each of 6 basic emotions selected from the ‘Pictures of Facial Affect’ (Ekman and Friesen, 1976). In a second test computer-morphed facial expressions were used. Even when perceptual impairments were found, people with facial paralysis still perceived many of the facial expressions shown to them. This may suggest that the ability to produce facial expressions is not a necessary prerequisite of their perception.

A difficulty with this study is the employment of prototypical, high intensity, still photographs as stimulus material. Such stimuli may in fact activate an automatic reaction due to their extremity that is not found for weaker non-prototypical expressions. And there is no evidence showing that this primitive response is inhibited in people with congenital facial paralysis. Using expressions that are not chosen according to their correspondence to an emotion stereotype is therefore an important consideration. To enhance ecological validity in studies of facial expression recognition in people with facial paralysis, dynamic facial expressions should be chosen. Like the drawing of an upside-down face, a static face may make it difficult to see clearly what expression the face expresses. Wittgenstein writes: 

Hold the drawing of a face upside-down and you can’t tell the expression of the face. Perhaps you can see that it is smiling, but you won’t be able to say what sort of a smile it is. You wouldn’t be able to imitate the smile or describe its character more exactly.

And yet the upside-down picture may represent the object extremely accurately. (Wittgenstein, 1980a, §991) 

A facial expression that was completely fixed couldn’t be a friendly one. Variability and irregularity are essential to a friendly expression. Irregularity is part of its physiognomy.

The importance we attach to the subtle shades of behavior. (Wittgenstein, 1980b, §§615-616)

Some people with Möbius Syndrome may reveal perspective taking and rapport through their other channels of expression: gesture, prosody of voice, enriched vocabulary, and so on. Other people with congenital facial paralysis, however, may rely on more introspective means to understand and communicate their experiences. Wittgenstein mentions the possibility of an associative link between language and experience: ‘I simply associate names with sensations and use these names in descriptions’ (Wittgenstein, 1958, §256). There is qualitative evidence that some adults with Möbius form an associative connection between language and experience to compensate for the lack of facial mobility. James, an adult male with Möbius, said in an interview:

Of course since I have never been able to move the face, I’ve never associated movement of the face with feeling of an emotion. When there are things which are sad I tell the person that I feel sorry for you but that I am thinking that rather than feeling it. (Cole, 2000, p.255)

When asked about first meeting his future wife, James replied: 

I think initially was I thinking I was in love with her. It was some time later when I realized that I really felt in love. I do think I get trapped in my mind or my head. I sort of think happy or I think sad, not really saying or recognizing actually feeling happy or feeling sad. Perhaps I have had a difficulty in recognizing that which I’m putting a name to is not a thought at all but it is a feeling, maybe I have to intellectualize mood. I have to say this thought is a happy thought and therefore I am happy. (Cole, 2000, p.254)

Some adults with Möbius may consequently experience sensations and feelings quite differently from the others in whose language names of experiences are connected with behavioral expressions, and even from those with congenital facial paralysis who can overcome the loss of psychological connection with others. These individuals may have a reduced capacity for communicating experiences and creating rapport with interaction partners. James added:

I think also that I have a fear of being out of control with emotions, feeling something that I can’t manage. I have also found it very difficult to communicate feelings throughout my life, whether as a child with my wife, though I think I am getting better at it now. I don’t really know how I communicate happiness or sadness. That’s a very hard question. Some people cry when they’re sad. I don’t think I cry. I sometimes felt that I would like to be able to cry but, you see, I am not really able to cry, my tears can come but there’s nothing else. My tears only flow when I eat. I am afraid of such feelings. I try and shut them off. (Cole, 2000, pp.254-255)

5.2 Möbius Syndrome and emotion recognition 

Suppose someone had always seen faces with only one expression, say a smile. And now, for the first time, he sees a face changing its expression. Couldn’t we say he hadn’t noticed a facial expression until now? Not until the change took place was the expression meaningful; earlier it was simply part of the anatomy of the face. (Wittgenstein, 1980b, §356) 

The blank and expressionless face of congenital facial paralysis appears to be part of the ‘anatomy of the face’, and is not to be taken by itself as a meaningful facial expression. A completely static face would not be an expressive face (Wittgenstein, 1980b, §614). Suppose, however, that a face paralyzed from birth alters for the first time, and smiles. Maybe the face smiles in response to the facial expression of an interaction partner. Or, the face smiles when given the command to do so. In any event, could the statement ‘Make a happy face, and you will feel happy’ be true in this exceptional case?

Think of children with congenital facial paralysis who receive muscle transplants to improve lip movement (Goldman et al. 2003). Suppose a child reports following surgery ‘Now I feel much better: the feeling in my facial muscles and round about the corners of my mouth is good’ (Wittgenstein, 1980a, §454). This statement may be taken by the child’s surgeon as communicating something highly meaningful since it implies the success of the procedure and postoperative rehabilitation. Certainly, it would sound strange under normal circumstances because when talking about myself feeling better I do not intend to talk about what it looks like to feel better. I would be treating myself as if I were a different person. Normally, this is not possible in talking to others, but makes sense in the child who receives a facial muscle transplant. For the procedure is one way to make the child appear similar to others and therefore create a psychological connection. The child may now mimic the facial expressions of others which would make social interactions smoother and more harmonious. These experiences may transform the child’s fragile sense of self. In this case, it would really be as if the child were another person.

Wittgenstein writes:

And how does it come about that … I have a feeling of joy if I merely make a joyful face; a feeling of sadness, if I make a sad one? That, therefore, I can produce these feelings by imitating their expression? Does that show that muscular sensations are sadness, or part of sadness? (Wittgenstein, 1980a, §451) 

Wittgenstein’s last question in this remark asks whether there is a conceptual or empirical link between statements of emotions and statements of expressions of emotions. He continues on:

Suppose someone were to say: ‘Raise your arm, and you will feel that you are raising your arm.’ Is that an empirical proposition? And it is one if it is said: ‘Make a sad face, and you will feel sad’? (Wittgenstein, 1980a, §452)

Let us briefly investigate these questions. Is ‘Raise your arm, and you will feel that you are raising your arm’ an empirical statement? This statement can be false in situations where a person is intoxicated by a drug which deadens his limbs, so that he feels nothing. This suggests that it is an empirical statement. By contrast, it will be false only in exceptional situations, whereas typically we feel sure that the feeling that one is raising one’s arm is simply part of raising one’s arm. Finally, it seems unlike what we may wish to call a conceptual truth or analytic statement.

Now, is the same true of the statement ‘Make a sad face, and you will feel sad’? When we mimic intense or prototypical facial expressions of sadness we do not normally observe ourselves to find out how it feels to be sad. Such displays may activate a reflex-like response due to their extremity that may not be found for less extreme expressions. It seems possible in the mimicry of less prototypical or weaker facial displays that we may observe ourselves, trace our feelings, and even compare them with the emotion that causes these changes in us (cf. Wittgenstein, 1958, §§585-588; 1980b, §§156; 722). In such a situation an observer may recognize he is imitating a sad face and literally feels that he is sad. This suggests that the mimicking observers may use their own muscular sensations and feelings as a means to recognize the interaction partner’s emotional state where the emotion displays are relatively weak and non-prototypical.  

Wittgenstein himself does not settle the problem of whether there is a conceptual or empirical link between statements of emotions and statements of expressions of emotions, but he does cast doubt on the claim that muscular sensations or affective states are to be included as elements of our emotions.  He argues:

Now granted – although it is extremely doubtful – that the muscular feeling of a smile is a constituent part of feeling glad; – where are the other components? Well, in the breast and belly etc.! – But do you really feel them, or do you merely conclude that they must be there? Are you really conscious of these localized feelings? – And if not – why are they supposed to be there at all? Why are you supposed to mean them, when you say you feel happy? Something that could only be accompanied through an act of looking – that’s at any rate not what you meant.

For ‘sorrow’, ‘joy’ etc. just are not used like that. (Wittgenstein, 1980a, §§456-457) 

Our words for emotions like sorrow, joy, and so on, are used for affective states which we do not need to find out about. And whatever is part of these emotions is something we automatically perceive, not through making an introspective effort or an inference. Some of Wittgenstein’s remarks on facial mimicry and emotional contagion may employ prototypical, high intensity expressions as primary material, whereas we have argued that the mimicking observers of subtle or weaker facial expressions may use their own muscular sensations and feelings as a means to recognize the interaction partner’s emotional state. Hence, the question of whether individuals mimic the type of expression they perceive in everyday life deserves further investigation.

5.3  Ostracism

Partial or complete ostracism from a form of life is one of the most psychologically damaging experiences that an individual can endure (Williams, 2001). It is possible that being ostracized from a form of life would be a strong contextual factor that would stimulate the tendency to mimic the behaviors of an interaction partner. The inability to mimic through loss of facial expression may therefore place a person at an even greater risk of being ostracized by unknown others. Cole (2001) interviewed a person with congenital facial paralysis who described the ‘daily horror of walking down the street, not knowing if people would say hello to him or not and not knowing how to respond’. The relationship between facial mimicry and affiliation may heighten the fear of rejection in some people with Möbius. Creating rapport and interpersonal closeness with others involves a risk so great to the sense of self that some individuals avoid relationships with others and retreat into themselves. James reported: 

I have a notion which has stayed with me over much of my life – that it is possible to live in your head, entirely in your head. Whether that came out of my facial problem I don’t know. I was very introspective. I divided people into two categories: those who didn’t want to have anything to do with me for various reasons and those who did. (Cole, 2000, p. 254)

I had feelings of low self-esteem and loneliness and isolation in company. It is only very recently that the whole area of non-verbal communication has even come to my attention. I know now that since I put out a reduced range of signals I receive back a similarly reduced range. (Cole, 2000, p. 254)

6 A final note

In this paper, we have highlighted what mimicry is and indicated its adaptive significance in Wittgenstein’s thought. We also suggested that Wittgenstein relates mimicry to affiliation, and that mimicking the behaviors of others encourages inclusion in a form of life and maintains harmonious relationships with other life-members. Individual differences in the desire to affiliate may influence behavioral mimicry and contribute to rapport and interpersonal relatedness with others in the form of life. Empathic individuals who adopt the perspectives of others as perspectives may mimic people more than people low in empathy. The inability to mimic through congenital loss of facial expression may lead to an avoidance orientation in some individuals, and intrapersonal disorientation. Situational factors that create a desire to affiliate such as Möbius Syndrome may stimulate more mimicry through remaining channels of expression. This suggests that people with congenital facial paralysis may mimic others through expressive-behaviors such as prosody of voice and gesture.
