Abstract
When cats are given closed field test problems which do not permit direct visual solution, they frequently re‐enter parts of problems which have already been explored; this behaviour is less typical of rats. Six albino rats and 6 mongrel cats were given 30 days practice on problems designed to maximize opportunity for re‐entry errors. Compared with test performance of subjects in a previous experiment in which special training was not given, cats made large and significant (p<.01) reductions in errors while rats showed little change in performance. Rats showed high start latencies and slow running speeds on the first run given each day, while latencies and speeds of cats remained the same over the eight daily runs.
