Jakob Hohwy - Perception as causal inference

Question 1

Perception as causal inference

Answer 1

Perception involves inferring causes from sensory input.

Question 2

Constraints on perceptual inference

Answer 2

Biases and prior beliefs influence perception.

Question 3

Perception and Bayes’ rule

Answer 3

Perceptual inference involves ranking hypotheses based on likelihood and prior probability.

Question 4

Unconscious perceptual inference

Answer 4

Helmholtz proposed the brain unconsciously infers causes of sensory input using Bayes’ rule.

Question 5

Perceptual inference and binocular rivalry

Answer 5

Binocular rivalry demonstrates the brain’s hypothesis-testing nature.

Question 6

How do neurons know Bayes?

Answer 6

Neurons may engage in Bayesian reasoning for unconscious inference.

Question 7

From inference to phenomenology

Answer 7

Perception involves a hierarchical process influenced by prior beliefs.

Question 8

A hierarchy of causal regularities

Answer 8

Causal interactions shape our perception of the world.

Question 9

Perceptual variance and invariance

Answer 9

Perception becomes more invariant as it relies on slower regularities.

Question 10

Message passing between hierarchical levels

Answer 10

Message passing between levels of perception ties the hierarchy together.
