P(H∣E) = P(E∣H) P(H)​ / P(E)

What is prediction error?

The difference between what you expected to happen and what actually happened

How do you calculate prediction error?

actual value - predicted value = prediction error

How long is prediction error in an EEG?

400ms

What is the neurophenomenological hypothesis?

our conscious experience is our internal model! we never experience the world as it is, only our simulation

What is the phenomenal self model?

we have to represent ourselves (an active agent) within our simulation

What are hyper priors?

representations of physics (distance, time etc). they must be very precise to restrict possible hypotheses

How do autistic individuals experience predictive processing?

Increase strength of sensory evidence, all prediction errors treated as important

Hard to identify faint patterns

What are hallucinations?

false perceptions

What are delusions?

persistent bizarre or irrational beliefs that are not easily understood in terms of an individuals social or cultural background
