Perception\, according to an emerging vision in computational and cognitive neuroscience\, depends heavily on prediction. Rich\, world-revealing perception of the kind we humans enjoy occurs\, these stories suggest\, when cascading neural activity matches the incoming sensory signal with a multi-level stream of apt &lsquo\;top-down&rsquo\; predictions. That same story suggests that perception\, understanding\, and imagination &ndash\; which we might intuitively consider to be three distinct chunks of our mental machinery &ndash\; are inextricably tied together\, emerging as simultaneous results of that single underlying strategy. Action\, surprisingly\, may be treated using much of the same apparatus. In the talk\, I first introduce this general explanatory schema\, and then discuss these (and other) implications. I end by asking what all this suggests concerning the fundamental nature of our perceptual contact with the world.
