The Origin of the Cat’s Responses to Rats and Mice (Kuo — 1938)
A summary of Recent Experiments in Psychology — 1938 Edition
Is rat killing in cats “instinctive”?
The word “instinct” possesses so many unscientific connotations that it has fallen into disrepute among most psychologists. For this reason, a more satisfactory way to state the problem of these experiments is to say that their aim has been to discover to what extent rat killing is a native mode of behavior and to what extent it is acquired.
