Daniel Povinelli - Böcker

In every domain of reasoning-from time and space, to mental states and physical illness-humans deploy an exceedingly diverse range of intuitive 'theories' about how the world works. Children from diverse cultures always seem to arrive at a few, common folk theories as they hone their developing brains against roughly similar interactions with people and objects. The result is an impressive panoply of folk notions that the human species uses to explain, predict, and just plain talk about everything from why the sky is blue, to why we catch a cold when we stand out in the rain. Unquestionably, all of this "higher-order" reasoning rests upon a diverse and complex tool-kit of "lower-order" neural and bodily mechanisms, much of which humans share in common with other species (and which, collectively, are quite clever in their right). But this book asks a different question: Are humans alone in trying to make sense of the world by postulating theoretical entities to explain how the world works?Povinelli and his colleagues approach this highly controversial territory by investigating the seemingly prosaic topic whether chimpanzees wield roughly the same commonsense ideas about weight that human do. When it comes to the physical world, they ask if chimpanzees reinterpret a broad range of primary experiences-lifting objects, seeing objects fall or collide, observing the differential effort others exert when they move objects-in terms of a common, causal mechanism which, in our everyday parlance, we refer to as 'weight.' The question is not whether chimpanzees have a theory about weight that's any better or worse than preschool children or Einstein or modern string theorists. The question is whether chimpanzees have any theories at all. And the answer comes in the form of over 30 never-before-published experiments from a decade-long research project involving seven adult chimpanzees and one hundred and twenty preschool children. Povinelli's work encourages us to stand back and adopt a different perspective on even our closest living relatives. Rather than seeing chimpanzees as watered-down versions of ourselves, this book challenges us to see our joint encounter for what it is: a meeting of alien minds.

From an early age, humans know a surprising amount about basic physical principles, such as gravity, force, mass, and shape. We can see this in the way that young children play, and manipulate objects around them. The same behaviour has long been observed in primates - chimpanzees have been shown to possess a remarkable ability to make and use simple tools. But what does this tell us about their inner mental state - do they therefore share the same understanding to that of a young child? Do they understand the simple, underlying physical principles involved? Though some people would say that they do, this book reports groundbreaking research that questions whether this really is the case.Folk Physics for Apes challenges the assumptions so often made about apes. It offers us a rare glimpse into the workings of another mind, examining how apes perceive and understand the physical world - an understanding that appears to be both similar to, and yet profoundly different from our own. The book will have broad appeal to evolutionary psychologists, developmental psychologists, and those interested in the sub-disciplines of cognitive science (philosophy, anthropology). The book additionally offers for developmental psychologists some valuable new non-verbal techniques for assessing causal understanding in young children.
