Applied Motion Study
A Collection Method to industrial Preparedness

204 APPLIED MOTION STUDY when using the chronocyclegraph device; the worker is not only interested in the electric lights and their various paths and orbits of dots and dashes, but is most anxious that these paths shall be those of the greatest skill and the fewest num- ber of motions possible. The various methods used with these various types of apparatus, which are usually new to the worker, present problems in psychology which are interesting to the worker as well as to the observer. The worker is quick to note that, with the new conditions attending the measuring work, his own process varies for a short time at the beginning from his unusual habits, because of the entering of the variables of the apparatus and the strange conditions that it involves. He is quick to notice, also, that this effect of strange- ness soon disappears, and that he then works ex- actly in accordance with his normal method. This period of strangeness, far from being a dis- advantage, is, on the contrary, often a great ad- vantage. The worker is almost sure to revert to the former habit, and an investigator or observer often gains valuable clues not only to excellent standards, but to necessary methods of teaching
