Abstract: In an attempt to observe the effect of social isolation on learning in rats,comparisons of learning ability were made between rats reared in gregarioussocial conditions and those reared in isolation. Learning ability was determinedby means of spatial water maze, signal water maze and food maze. The resultsindicated that the rats reared in gregarious social conditions did better thanrats reared in isolation at learning a series of mazes. Isolation decreased the learning ability of the rats. The more complex thelearing-maze, the more obvious was the effect of isolation on learning ability.
