- Template theories
- Feature theories
- Recognition-by-components theory
The theory that says that the information in our sensory receptors, including the sensory context, is all we need to perceive anything.
Direct perception (Direct perception theory).
These theories suggest that we have stored in our mind myriad sets of templates.
