What is signal detection theory?
Our ability to detect and perceive sensory signals will changes as a function of our states
What are response criteria?

What is figure-ground differentiation?

What is color constancy?
The brain’s tendency to hold color perception constant even as the amount of light varies
What is shape constancy?
