It may seem as though the world just pours itself directly into our minds through the transparent windows of our eyes and our ears.
But psychologists have long known that perception is not simply a “read out” of sensory information. We are strongly influenced by context. From the effect of shadows on how we perceive the brightness of a surface, to our tendency to interpret facial expressions depending on what we think is happening, context permeates all our conscious experiences.
Some researchers, myself included, go even further. Instead of context merely influencing the contents of perception, the idea here is that perceptual experience is built from the top down, with the incoming (bottom-up) sensory signals mostly fine-tuning the brain’s “best guesses” of what’s out there. In this view, the brain is continually making predictions about the causes of the sensory information it receives, and it uses that information to update its predictions.
