The slightest movement in its presence may call forth the native tendency of flight with the suddenness of a simple reflex. Subjects trained with electric shock had to be forced through the door between the nest box and the entrance chamber, and here in the presence of the electric boxes the primary motive for choice seemed to be to escape from the situation. If, as all these experiments indicate, there is a point of interference as the strength of stimulus is increased this point should be reached much sooner with the rat than the dancer. And the interference due to excitement will appear much earlier in the series of diflicultness with the rat than with the dancer. Thus the most favorable strength of stimulus for habit formation in the rat should be weaker than the most favorable strength of stimulus for the dancer and interference due to excitation should be more noticeable in the rat than in the dancer. SUMMARY OF FACTS TO BE EXPLAINED The above results present certain obvious facts which need interpretation. Why should rats of similar heredity and environment perfect a like habit in so widely different lengths of time when trained with different degrees of hunger? Why should subjects of similar heredity and environment perfect a like habit in so widely different lengths of time when trained with different strengths of electric shock? Why should subjects with the same heredity and similar environment perfect a like habit in so widely different lengths of time when trained with hunger and when trained with electric shock as motives? Subjects trained with the most favorable condition of hunger perfected the...show more
