MERLIN DONALD Professor Emeritus at Queen’s University in Kingston, ON, Canada Cognitive evolution: IMPLICATIONS FOR DEVELOPING A CREATIVE MINDSET Cognitive evolution: Implications for developing a creative mindset Merlin Donald The study of cognitive evolution reveals a great deal about human nature. Human evolutionary prehistory suggests strongly that our species was highly skilled long before it was articulate. Our ancient ancestors survived and prospered due to their capacity to refine tools, and especially, their ability to make the master toolkit – the toolkit that was used to manufacture other tools from softer substances. The sharpest and hardest substances available in the Stone Age were flint and obsidian, and Acheulian tools made from these two materials have been dated back to approximately 1.8 million and 1 million years ago, respectively. Manufactured things and environments constitute the basis of what is known as material culture. Material culture surrounds us, serving as our virtual cognitive ecology. All human beings must adapt to the specific material culture in which they are born. Modern material culture includes electronic gadgets and the internet, among other things, but the process of creating, and adapting to material culture started long ago, in evolutionary events that occurred during the Old Stone Age. With flint and obsidian, ancient humans were able to make an assortment of tools from materials such as wood, hide, and bone: diggers, spears, tethers, simple clothing, and eventually, shelters and boats. But how could they manufacture a master toolkit from such hard substances as flint and obsidian, if nothing else in nature was sharp enough to cut and shape them? That is exactly the key question – it was not easy! It takes a modern anthropologist several weeks of training to learn how to do this, and yet, our distant ancestors were doing it nearly 2 million years ago. It is important to realize that although the neuropsychological foundation of toolmaking may appear to lie in better visualmanual coordination (which is partly true), it involves much more than the hands. In fact, this remarkable ability, when it first appeared, signalled major changes to executive brain systems located at the top of the primate cognitive pyramid. EVOLUTIONARY ROOTS OF FANTASY PLAY: THE MIMETIC IMAGINATION The most important consequence of this change was the appearance of what I call the “mimetic imagination,” which evolved at the top of the primate mental hierarchy, and is the basis of the ability to rehearse skills. Practicing a skill demands the capacity to assess a previous performance, imagine an idealized outcome (this is the mimetic imagination at work), and then improve the next performance, assessing progress, over and over again, until the result is closer to the ideal. Athletes can imagine their perfect performance, and try to execute their role as well as they can, evaluate the result, and repeat the sequence, over and over again, to improve We can conclude that the most ancient defining characteristic of the human mind is the ability to make things with other made things. Our dance with made things started millions of years ago, and it is still the center of the human universe. We have moved from stone tools to satellites and silicon chips, and the creative mind at the center of this interaction still dominates the process. Cultures of Creativities 12 their skills. So can actors, craftsmen, and performance artists in various fields. They envision a future scenario, and try to approximate an imagined, improved version of their previous performances. This is what our distant ancestors had to do to master tools. And so do our children, as they experiment within the context of a modern world of vastly increased possibilities. This same basic mental apparatus is the foundation of fantasy play, which entails imagining a virtual world, and acting out various roles in it. of any skill. In this sense, it is a “supra-modal” capacity, that is, located above the specialized sensory and motor modalities, and able to employ any of them. This allows us to assemble our actions into elaborate hierarchies that weave and combine various sensory and motor sub-systems into complex skill systems. A good modern example is learning to drive, where we have to learn several more specialized skills, such as backing up, using a mirror, steering, braking, and parking, until these subsystems (complex enough in their own right) are eventually unified, through extensive practice, into a smooth unified hierarchy that allows us to drive through heavy traffic. This ability – to imagine and improve a performance scenario – is very special to our species. Animals simply do not rehearse and refine skills. As a result, they cannot create, assemble, and self-install novel skill systems. Apes throw things at one another when fighting, but you will never see a chimpanzee practising his throwing, over and over, to improve his tech nique. We might make an exception to this statement for the vocalizations of certain songbirds, but their mimetic talent appears to be modality-specific and limited to vocalization. In contrast, we know that human ancestors had the essence of a more general, more powerful kind of mimetic imagination almost 2 mil lion years ago, when the first Acheulian stone tools appeared. Even so far back in time, their capacity was neither modality-specific nor restricted in its application; their new capacity was able not only to improve existing skills, but also to invent new tools that suggested new possibilities, and, in turn, demanded new skills. Mimetic imagination served as the platform for later evolutionary changes to the modern mind, including even such advanced innovations as literacy. Literacy gave us a new master toolkit that cultivated skills in abstract domains of thought and memory. Like the hand axes of the Stone Age, writing came from innovations in material culture, created in the mimetic imagination, and is supported by skills learned through endless practice and rehearsal. Our imaginative interaction with material culture continues. It has increased our mental toolkit immeasurably, and revolutionized how we do our cognitive business, especially how we think and remember in organized groups. THE CYCLE OF CREATIVITY This evolutionary reflection leads us to the creative cycle that drives human cultural innovation. Human beings have existed in a complex creative relationship with tools for millions of years. The human mimetic imagination is thus inherently creative. It is also a highly flexible capacity, and can supervise the learning Cultures of Creativities 13 were devised for a very different technological world, and our approach to education probably needs to be re-examined at the axiomatic level. However, it is also true that the basic needs of the human individual have not changed, and that the creative engine of cultural change lies, as always, inside our minds and brains. We need to tap the creative potential of children in order to optimize their ability to cope as adults in a society that demands life-long flexibility and adaptability. Our success in doing this will determine whether our civilization can survive. Tools, whether simple or complex, are a major part of the cognitive ecology that we have built for ourselves to live in. This teaches us a few practical lessons about the sources of creativity in children. First, when viewed in this broad historical framework, it is obviously the most natural thing in the world for human children to play with simple tools to make things. In doing so, they are engaging the most ancient and unique features of our special human mentality. Failing to allow children to cultivate their imaginations would be to break faith with our ancestors, and to miss out on developing core abilities that will serve as the foundation of their future development. Children at play are engaging in the serious business of building the cognitive platform for their future skills. They are not only assembling essential neural architectures in their young brains, but also encouraging the development of their creative capacities, as well as their proficiency at constructive selfcriticism. These abilities are essential, and their future as learners depends upon it. Evolution also throws light on why fantasy play is so much fun. There are no motivational problems here, unlike many other aspects of education and development. It is natural to engage in fantasy play, precisely because it is such an ancient, adaptive, and necessary activity. Moreover, it is inherently creative. A mimetic performance always has an element of unpre dictability, and requires imaginative innovation to overcome obstacles to success. Fantasy play is at the root of both art and science. Of course, long training is needed to turn creative children into success ful adult innovators, and not all will succeed. But early inter vention is an essential step in giving children a good start in using their minds independently to invent imagined futures. Only later will a child learn how to cooperate with and organize others to carry out projects together; some will progress to the more abstract and socially connected stage that we know as entrepreneurship. But the germ of creativity must be stimulated early, so that the imagination is given full rein to grow to its full potential, especially in those crucial preschool years. REFERENCES Donald, M.
