Full Idea

Psychologists have attempted to determine whether a concept of a category stores some causal knowledge about the members, some knowledge about their typical properties, or some knowledge about specific members.

Gist of Idea

Do categories store causal knowledge, or typical properties, or knowledge of individuals?

A Reaction

I take there to be a psychological process of 'generalisation', so that knowledge of individuals is not and need not be retained. I am dubious about entities called 'properties', so I will vote for causal (including perceptual) knowledge.
