Learning is reasoning as a scientist
theories of learning: the hypothesis that the brain behaves like a budding scientist. According to this theory, learning is reasoning like a good statistician who chooses, among several alternative theories, that which has the greatest probability of being correct, because it best accounts for the available data. How does scientific reasoning work? When scientists formulate a theory, they do not just write down mathematical formulas—they make predictions. The strength of a theory is judged by the richness of the original predictions that emerged from it.

In each of our minds, ignorance is gradually erased as our brain successfully formulates increasingly accurate theories of the outside world through observations.
(p.43)
To learn is to be able to draw as many inferences as possible from each observation, even the most uncertain ones
(p.44)
the more improbable an experimental observation is, the more it violates the predictions of our initial theory, and the more confidently we can reject that theory and look for alternative interpretations.

hypotheses come from a top-down signal. From the cortex to the lower sensory areas.
⇒Top-down Processing
bottom-up signals come from the outside word. The sensory areas send the signals up to the higher-level cortex where the areas compare the bottom-up signals with the predictions made before. This should create an error signal. If not the model was right.
