Abbreviated introduction: The purpose of this experiment is to investigate the relationships between "place" or "response" behavior of white rats and two other variables, their performance in a reasoning situation and speed of learning a maze habit. It is possible that animals which exhibit "place" behavior perform more efficiently on the reasoning tasks and learn more rapidly than the "response" lecimers. This does not imply a causal relationship in either direction but it is a beginning attempt to solve the apparent contradictions found in the literature on these topics. As a first step in the study of these relationships it will be necessary to investigate the consistency of the "place" or "respraise" behavior of these animals. If this is found to be inconsistent no consistent relationships with other phenomena are possible ... The results of these experiments are thus ambiguous and the issue remains unsolved. It is not the purpose of this experiment to determine whether reasoning does occur in the white rat. This must be done by other experimentation. However, the detour behavior shown in these situations will be called reasoning. No studies have been discovered in the literature on the relationship between the speed of learning a maze habit and what is learned. If a relationship is found, it may throw light on the differences in the behavior of the animals in what appears to be the sane situation. Once again a causal relationship cannot be implied. This study undertakes to investigate the following problems: 1. Does the white rat exhibit consistency in what is learned? This can be further divided into the animals' consistency in the same and different situations. 2. What is the relationship between what is learned and reasoning behavior? 3. What is the relationship between what is learned and speed of learning a maze habit?
