Applied Motion Study
A Collection Method to industrial Preparedness

90 APPLIED MOTION STUDY its significance, and, therefore, the model must be brought to this state of perfection before it is considered complete. Where a chronocyclegraph motion model is desired, the spots on the chrono- cyclegraph are represented by spots painted upon the model. Black and grey paint being used upon the wire model that has been painted white, the result is spots of white fading through grey to black, that resemble closely in shape the white spots seen in the chronocyclegraph. It is possi- ble also to use the ear in teaching. Through a new device consisting of a pendulum, a bell and a flashing lamp, time records, simultaneous with the other motion and time records, can be made. The same devices can be then set in operation while the work is being learned, and the learner can count by listening to the bell at the same time that he is learning through his eyes or his fingers by means of the motion model. The significance of all these devices to psychology and education can only be appreciated by a dose examination of the models and cyclegraphs themselves, and an observation of their methods of recording habit or lack of habit, decision or indecision, grace or awkwardness, etc. Habit is best re-
