In recent years the Science of Nutrition has made tremendous strides. It has at last been recognized that our diet affects significantly our physical as well as our psychological well being. Although a great deal of work has been done on diets from the physiological standpoint, very few investigations have been concerned specifically with a psychological approach. The present experiment is designed to study an aspect of the Science of Nutrition from the psyohological approach. While this undertaking was not concerned specifically with either the sciences of Psychology or Nutrition, it was an attempt to experiment in that region where the two disciplines overlap. It was an attempt to associate the two sciences. For it is on the overlapping areas of scientific disciplines that there remains much ignorance, and where research is needed. The object of this experiment is to investigate the effect of a diet deficient in vitamin B on learning ability in rats. Further details will be given in the following chapters. The writer of this thesis does not make claim to much originality. It was rather his attempt to verify the conclusions and to refine and improve the techniques of other workers. The work was begun on December 26,1939. It was concluded about August 24, l940. The writer designed and constructed 25 rat cages, 3 Carr Mazes and 3 galvanized tin tanks.
