Our researches have especially been made into the results produced on the effectiveness in learning by the structures (or process) of learning. In such experimental and substantial researches as these, there appear in the results the effects of various influences of psychological function. In fact, it is presumed that the recognition is achieved as a result of the synthesis of such psychological function.
