It was hypothesized that sensory deprivation inhibits the intellectual development of animals. To
test this hypothesis an experimenter used two rats, each of whom had just given birth to eight
pups. One rat and her litter were placed in a large cage with ample space and with objects to
explore. The pups of the second rat were separated from the mother, and each was placed in a
separate cage. These cages were quite small, and the only objects they could see (or hear) were
the four walls and the food dispenser. After five months both treatment groups of rats were tested
in a multiple-T maze using food as a reward. After 20 trials all of the nondeprived pups were
running the maze without error. On the other hand, the deprived pups were still making several
errors in the maze. This latter group of rats frequently \"froze\" in the start box and in the maze
and had to be prodded to move. The experimenter concluded that sensory deprivation inhibits
intellectual development such that deprived rats did not have the intellectual ability to learn a
simple maze.
