Excerpt from Teachers College Record, Vol. 6: A Journal Devoted to the Practical Problems of Elementary and Secondary Education and the Professional Training of Teachers; January, 1905; Educational Psychology The study of perception brings in the new element of sensa tion, which now demands study. Here there is comparatively little Of value for teachers. The creative nature Of the sense process is made manifest. The fact is pointed out that our organism is capable of responding to very few of the myriad vibrations which probably surround us. The selective nature of our physiological mechanism and of our consciousness is brought out, and the laws of sensation are experimentally demonstrated - the law of the threshold, that of subliminal stimuli and summation of stimuli, of specific energy of nerves, of relativity and fusion of sensations. After this general survey the sense Of sight is treated somewhat fully as a type. This study of sensations-and sense organs leads inevitably, if the students have any life at all, into questions about the structure of the brain. With the aid of slides and microscopes, models, and charts, a teacher can in two or three two-hour periods give all that the average student needs in order to under stand the reflex and volitional mechanism, and to get some idea of the physical basis of association, memory, and the like. This is followed by a lesson on localization of function in the brain, and the study of so much of the gross anatomy as can be gotten by the dissection of a Sheep's brain during two periods of labora tory work.
