The lovely people from the brainstorms group invited me to give an online talk about predictive processing. Predictive processing theory suggests that all brain functions depend on comparisons between ongoing actual experiences and the brain’s expectations. It suggests that expectations and predictions about reality are, probably, more important than the direct live sensory evidence that the brain receives. But is it just a new data modelling method? Does it describe just one aspect of cognition? No, there is much more potential. Let us look at the loose ends of present day cognitive (neuro)science to see why we can be really excited about predictive processing.
