Dancing with Design: Some Insights from the Perspective of Human Evolution on the relationship between the Body, Gesture, the Unconscious and Design Design: Body: Sense Annual Conference, Design History Society University of Kingston Surrey U.K. 5 ? 7 September 2007 It is an ordinary day. You are leaving the house. You reach out for the keys on the hook in the hall and walk out, closing the door behind you. These actions are familiar, automatic. You take the usual walk to the shops, thinking about what you might buy for supper and where you might buy it. Walking demands little or no conscious effort, and your surroundings pass largely unnoticed until, suddenly, you see a space, where a building has just been demolished. You take in the unfamiliar view. Still walking, you take out your mobile phone and ring a friend to suggest a visit. The friend needs a little persuasion. You persuade, gesturing as you do so at your unseen - and unseeing telephone correspondent. You put the phone away. A little further on, across the street, you notice two people talking animatedly to one another. You can see them quite clearly, but you are too far away actually to hear what they are saying. Even so, you ?read? their body language, and you can tell ? or think you can tell - that they are having a row, or an affair, or sharing a joke. You shop and go home. Later that day, you drive to your friend?s. You arrive, having followed your usual route, unaware of the precise sequence of gear changes, turns of the steering wheel, pressure applied to brake and other pedals that got you there. On your arrival, after greetings, you settle into a familiar armchair while your friend makes you both a cup of tea, reaching for the tea, the kettle, the tap, and the teapot, all in their familiar places. It is an ordinary day. In ordinary life, our unconscious brains are fairly constantly at work. With regard to our bodies, they seem to take care of two types of involuntary actions: practical activities, such as instructing our bodies to reach for the keys, or the phone, or the kettle, to walk, change gear, or settle into a chair; or expressive actions, such the gestures which may accompany speech, gestures which are so unrgent, that we can?t help but make them. If challenged after our phone call, we would acknowledge that, of course, they were unseen by the friend for whom they were ? unconsciously ? intended, but that would not stop us doing the same the next time. These two types of unconscious bodily movement ? practical and expressive ? overlap. Which of us has not sat at a caf? in the street and persuaded ourselves that a walk is revealing of character ? an understanding which is meat and drink to an actor. Gesture and body language can be reliable indicators of mood, temperament and intention. According to the psychologist, Jeffrey Gray, most unconscious physical actions might be thought of as ?goal? directed. He writes: ?We are unaware?of how we undertake actions, other than by way of percepts of the goals to which the actions are directed [such as becoming conscious that we have picked the keys up].? i Interestingly, he cites experimental evidence which shows that the speed at which a tennis player reaches for, makes contact with and returns a tennis ball, means that the entire action is accomplished unconsciously, and that the brain only constructs the conscious narrative of the event moments after the action has been completed. ii At this conference, we are considering the relationship of design to the body and the senses. I should like to develop a few observations with regard to the relationship between our unconscious and conscious uses of our bodies and our designed environments of spaces and artefacts. In doing so, I will be drawing on two types of evidence. I have spent the past few years trying to work out just how much design in human life remains to this day, in part, a function of our shared, evolved history as a species. Purely co-incidentally, at about the same time, I have been learning how to dance ? most recently, the Argentinian tango. Taken together, both the formal research and the dancing have fundamentally changed my conception of how design ?works?, and in this paper, I will be referring to both to illustrate, support and qualify my argument. It is noticeable when learning a new figure in dancing that, at first, not only may it look difficult to follow and understand, it also requires great, conscious, concentration. One observes others doing it; one imitates ? however clumsily at first. With each repetition, however, the move become easier, somehow, more ?naturalised?, internalised. The brain, body and senses (the sensorimotor system, if you prefer) learn, and as they learn, the move lodges somewhere in the brain (or should that be brain and body? ? I think it should), such that it can eventually be ?replayed? with ease. Surprisingly, it is eventually perfectly possible to execute complex moves while sustaining a conversation with one?s partner (though in truth, the most satisfying dancing rarely includes such an unnecessary addition). How can this happen? Part of the answer rests with the evolved, modular structure of our brains; iii where different parts process different types data. This understanding helps explain some commonplaces of the ways in which we physically ? and unconsciously ? engage with and negotiate our physical environments. As in the ?ordinary day? cited at the outset, there are countless occasions when our engagement with the designed environment is real, but at the unconscious level, only breaking into consciousness when the desired percept is delivered (keys grasped) or something goes wrong, or is not as expected. Much design today lives as image; doubtless many novel designs will have lives as virtual entities, but designs intended to enhance lives here and now in the physical world need, of necessity, to be satisfying at many different levels, including, I suggest, at this unconscious one. Such usually unobtrusive designs can contribute much to the ordinary pleasure of living. In the visual and emerging virtual ages, I hope we may come to value once more the finger plate on door which is to be pushed, cueing exactly the right, unconscious, goal orientated, physical action. As noted, involuntary, unconscious gesture is usually an accurate expression of mood or intention. Perhaps our ability accurately and rapidly to ?read? such gestures is but one example of how finely adapted we are towards the successful negotiation of our social environment, that is, we have evolved reliably to detect who might be an ally, who an enemy, who, perhaps a sexual partner, and who will be of no consequence to us at all. Does this affect our interaction with the things we design and live with? I think it has. I propose that we possess parallel abilities both to express and interpret socially valuable, adaptive data ? rooted in gesture ? through the devising and appraisal of artefacts. Of course, gesture and body language do not have to be involuntary. They can also be a quite deliberate, self-conscious performance, of which dance is just one example. Dance is a human universal. Merlin Donald, in a study sketching the origins of both our minds and of language wrote that ?Mimetic action,? ? by which he means ?mimetic? as in ?mime?, rather than ?meme? ? ?is basically a talent for using the whole body as a communication device.? iv The tango which I dance may, in part, have emerged among the men waiting their turn in the brothels of Buenos Aires in the late nineteenth and early twentieth centuries, v and been subject to any number of contingent developments since then. To that extent, my dancing is the end product of (in terms of evolutionary time) near-contemporary, cultural and other contingent factors; but mimesis, including both the involuntary gesture and the deliberate performance such as dance, plus the ability to interpret it, is probably very old indeed. Like Donald, Chris Knight (in company with Michael Studdart-Kennedy and James Hurford) believes that gesture and the use of the body to communicate is actually older than language itself. He writes: We are justified in regarding mimesis?as a unitary mode of representation, peculiar to our species, not only because it emerges naturally, independent of and dissociable from language in deaf and aphasic humans unable to speak, but also because it still forms the basis of expressive arts such as dance, theatre and ritual display. The dissociability of mimesis from language also justifies the assumption that it evolved as an independent mode before language came into existence. vi Though others place mimesis?s emergence alongside, rather than before that of spoken language, vii all are agreed on its antiquity, ubiquity and adaptive importance. How does this affect design? For hundreds of thousands of years, the ancestors from whom we are descended ? and whose genetic make-up we, in part, inherit ? created artefacts using their hands and simple tools. In the evolutionary environment, all effort expended should be thought of as a ?cost? to be offset against some adaptive advantage with regard to survival, reproduction, or both. viii In such circumstances, efficiency is adaptive and will be selected for. Hand working skills are physical, involve the body, and are acquired through emulation and repetition. They may take time to learn and, in that sense, are ?costly?. Hundreds of thousands of tools for various practical purposes survive from pre-history, as well as representational carvings or cave paintings which superficially resemble our modern notions of ?art?. In addition to the time spent foraging for materials and making these artefacts, how were these costs of ?skills acquired? justified? Most obviously, the tools were useful. A flint blade may have helped in hunting, in the preparation of food or skins, or otherwise been of practical value, helping offset the costs. Similarly, having noted the usefulness of what might be mistaken for useless art among modern hunter-gatherers, ix one may also legitimately speculate on the potential ?utility? of carvings or cave paintings as repositories, say, of wisdom about the recognising and hunting of game, x or the recording or augmenting of narratives, myths or rituals useful to the group in terms of identity and social cohesion. If these reinforce the will to survive and reproduce, then there should be corresponding increases in effectiveness in the securing of resources. xi These fairly obvious adaptive advantages may have offset costs. Need one look further? I think one must. It is worth noting that among our own species especially, and like many of our practical devices today, useful objects commonly have degrees of finish, levels of care taken over their form and structure, or additional work devoted to ornament or decoration that use alone cannot justify. Not only would this have taken more time to execute, the artefacts may well have been the result of skills practiced and deployed to levels which making it ?useful? alone might warrant. Both tools and ?artworks? appear, even to many modern eyes, attractive, and sometimes breathtakingly beautiful. No accident, surely? Indeed, no. All artefacts throughout human history ? including pre-history ? have the potential to serve as aids to social orientation. When made by hand, an artefact will, to some extent literally, physically embody the characteristics of the maker: there may be evidence of intelligence, of skill, of knowledge of resources, or of conventions, of inventiveness, of wit, humour and so forth ? or indeed, of the lack of these, or of their opposites. This data can be thought of as tacit social intelligence. In part, these qualities can be detected through the appraisal of, for example, the delicate, regular traces of a sequence of carefully calculated, repeated blows on the surface of a flint blade, or the strokes of ochre or other colourings which make up the animated representations of the teeming wildlife or apparently mythical figures in the cave paintings. All prehistoric, hand-made artefacts were, inevitably, records of gesture, and I suggest that whatever other adaptive value they may have had, and at whatever other levels they may have ?worked?, those which bore reliable traces of human gesture ? in a manner akin to the generation and interpretation of gesture itself ? provided tangible accounts of the character of their creators. And just as we are attuned to interpreting gesture, body language or dance, I suggest these traces of human action were similarly susceptible to appraisal, with corresponding, potentially adaptive benefits in terms of successfully negotiating one?s social environment. Sometimes evidence of those qualities may be the accidental by-product of an individual striving to achieve a practical, economic outcome, a bit like noticing how someone reaches for the keys. The data is unintended, but more or less reliable, and susceptible to detection. And, just as on the dance floor, where in principle at least, a tango couple are only interested in entertaining each other with the skill and invention of their brief, shared, spontaneous drama, but where such ?private? dancing is easily codified, formalised and perhaps exaggerated to become a spectacle for the benefit of others, so too, sometimes, and more commonly, perhaps, the creators of artefacts may have deliberately striven for the effects thought to exhibit favoured human qualities. So, for example, rather than being a by-product of effective making, regularity may also be sought for its own sake, creating the pattern which others may value. Further, as I have argued elsewhere, xii an artefact?s power to act as an embodiment of tacit social intelligence does not disappear, once it becomes remote from its creator (or its creator remote from it). On the contrary, as artefacts change hands (or the creators of cave paintings die), those who subsequently choose to be associated with the artefact are, whatever else they may be doing, choosing to be associated with the human qualities the artefact is judged both to embody and express. Thus the artefact may serve to articulate any number of social ? or sexual ? relationships, and enhance the ability of the individual successfully to negotiate their social environment. So much for human pre-history. Does this speculative account of the remote past, if true, have consequences for design today? I believe it does. Put simply, I suggest that each of us has inherited and is possessed of sophisticated, adaptive, neural equipment, refined over the hundreds of thousands of years of our ancestors? devising (designing, if you like), making and appraising hand made artefacts in order to facilitate social relationships. The value or manner of working of this equipment ? while it operates today in a much changed environment ? has not suddenly been wiped out, negated or fundamentally altered by the recent advent of complex machinery and computer-aided design and manufacture (CADCAM), let alone modern society and all that follows in its wake. In evolutionary terms, these developments have been with us for half the blink of an eye ? far too recent to have had much impact on our genetic make-up. On the contrary, while any number of contingent cultural causes may affect the detail of how designs emerge out of any particular context, and irrespective of the fact that many of today?s artefacts actually involve little or no hand work in their manufacture, I suggest that, on average, those designs in which the style of the lines, shapes or forms - physical records of ?gesture?, if you like ? corresponds to those which, if the object were hand- made, might reveal attractive human characteristics, tend to be commonplace and favoured, while those that do not are rare. xiii Finally, some caveats: this is only one of the evolutionary roots of our aesthetic preferences. Other include: preferences which emerged out of a still more ancient ability successfully to discriminate in the organic world between that which is sound, and so potentially good to eat, or to have sex with, or more likely to attack, rather than that which is rotten, sick, or dying; or another derived from the aesthetics of economy, that is, we find attractive the achievement of greatest effect by the minimum of means; or a further one ? often linked with sexual selection (that is, the accumulated effect of what it is that reproductive sexual partners value in one another) emerges from extravagance as an indicator of genetic fitness, in that more resources than are strictly necessary have been secured and displayed (a practice which equates neatly with aspects of Thorstein Veblen?s account in his Theory of the Leisure Class of beauty and luxury among the East Coast wealthy of late 19 th century America). These then, in this account, represent the ancient, rich evolved, architecture of our contemporary selves, in which the recent, culturally contingent factors we are more accustomed to consider, play themselves out. Only if this wider perspective is more fully appreciated will we have anything approaching a full understanding of the workings of design among us today. i Gray, p. 91 ii In improvised dance, too, it is common to find oneself in the middle of spontaneous moves one has little conscious sense of having commissioned.

Each group is geographically and culturally distinct from one another, so their stories have been created independently, rather being the products of cultural transmission. On the basis of this evidence, Sugiyama suggests that contemporary ?hunter-gatherers use narrative as a conduit of subsistence-related information?, that is, information about the securing of food and other resources. I suggest cave paintings may have supported similarly useful data.
