| Abstract: | According to an emerging vision in computational and cognitive neuroscience, perception (rich, full-blooded, world- presenting perception of the kind we humans enjoy) depends heavily on prediction. To perceive, if this schema is correct, is to meet incoming sensory information with a set of matching ‘top-down’ predictions – the brain’s best probabilistic guesses about the shape of the present sensory signal. This story suggests, intriguingly, that perception, understanding and imagination - which we might intuitively consider to be three distinct chunks of our mental machinery - are inextricably tied together, emerging as simultaneous results of that single underlying strategy. |
