1. Studies of the workplace - income and human body:
The right body, pay someone to write my paper the heels together, the line of gravity passing between the heels - the third, where the weight of the body falls on one leg , assuring the other the balance between one and the other alternating, the economy in oxygen consumed reaches 22%. Hence the rational modifications in the construction of seats and work benches (...) Its effectiveness, demonstrated at the same time by subjective judgment of the operators and the objective test of yield curves is remarkable. "19
2. Studies of the utensils and complex utensils (machine)
Adaptation of the machine to the man and increase of the yield: "(...) Walther proposed, therefore, numerous modifications of utensils, always aiming at the best adaptation of its forms, (the one through which the operator acts on the workable matter) and in the area of support (the one in which the limb of the human body rests to move them) .
The psychophysiologist has to do with the weight of the tool, its length , its cable, 'so that it produces on the mass to be worked the greatest effect with the minimum of effort.' Hire someone to do assignment It transforms the levers of a machine, the control cranks, in order to obtain the movements more economic and more conforming to the natural reflexes of the operator. "20 These principles were applied in the retrofit of a classic machine of the watch industry (a pivoteuse) with good results. The pivoteuse (machine to mold the spindles of the balancer shaft), being biologically rationalized, increased the productivity, reduced the training and the fatigue of the workers; a piece that lasted seven seconds to be manufactured passed to four seconds and learning the craft from five weeks to three and a half hours.
For G. Friedmann, the science of labor, with a special emphasis on the psychophysiology of work, runs counter to the results of Hawthorne's experiments. The results of these experiments highlight the psychosocial aspects of work organization as fundamental to productivity. Léon Walther created a method to measure the natural rhythm of the human being; with the use of only the stopwatch and the metronome, he believed in the possibility of man / machine management. Inspired by the laws of interference, he says: "The psychophysiological system of man can be compared to an engine: when the impulses in it are made according to the natural rhythm, the stimulating effects are added to it and its efficiency increases."
The rhythm - writes Leon Walther - is therefore the fundamental condition of a rational organization of labor. ' On the other hand, the rhythmic training of the operator, training, when it is so rhythmic, improves innervation, blood circulation, and invigorates the muscles: it is found that, at equal and carefully determined intervals for each individual, repetition of a group of movements allows them to automate them more quickly than any other process. "21 Applying the principles of psychophysiology to an alarm clocks assembly workshop has yielded good results in terms of "humanization" and productivity. In this workshop, work became "rationally organized", the natural rhythm respected. The workers began to work satisfied, without tension, and listening to their favorite novels in broadcasting sessions. Serial physical gestures began to be realized unconsciously, the workers, free of the degraded form of attention, could daydream, listen to music or read novels.
