In 1770, Wolfgang von Kempelen constructed the infamous Mechanical Turk. This automaton was supposed to play chess and even be able to complete the Knight's problem. Like the Digesting Duck, the Mechanical Turk amazed the audiences. However the machine turned out to be fake. Inside, a human operator was hidden. The automaton was bought in 1805 by Johann Nepomuk Maelzel, who also patented the metronome (another disciplinary instrument of labor performance, used for learning stenography).
Deloyloy also serves as an historical document, providing a detailed account of the events of the conflict even as it interprets and comments upon them. Names of key the figures of the resistance and names of the places are noted. Details such as how the British flew in reinforcements from India to battle against the Kurds are also described in the song. The main tone of this sonic battle for the Dengbêj is the notion of betrayal. Each stanza of the song closes with the refrain: Oh the Kurds, the traitors… This is an allusion to the internal divisions among Kurdish groups, some of whom collaborated with the British, such as the native policemen in the silence cabin, delivering the message in Kurdish, from inside the modified Victoria Vickers. Taken by the microphone, his voice is amplified 1.600.000 times, and pushed through the speaker cones, raining down as “verbal bombs”.
In 1850, Helmholtz succeeded in measuring the speed of nerve impulses, which he called physiological time. In the same vein, Franciscus Donders, a Dutch ophthalmologist, developed the Noematachograph in 1865 – a derivative of the famous Phonautograph by Edouard-Léon Scott de Martinville. With this apparatus, Donders was able to measure and record the ‘speed of thought’, or more precisely, the reaction time to a given stimulus. Opening the field of mental chronometry, this apparatus is the ancestor of attention tests in cognitive neuroscience. In 1895, Herman Griesbach developed the Esthesiometer, to measure mental fatigue by measuring the tactile sensitivity of the skin. At the turn of the twentieth century Alfred Binet, a French psychologist and hygienist, studied mental fatigue and carried out intelligence tests in schools to identify bad pupils. His efforts culminated in 1905 with the adoption of a metric intelligence scale (the precursors of IQ tests), designed to assess children's aptitudes in relation to the occupations they are destined to exercise. This also marks the emergence of professional orientation.
The german psychiatrist and eugenicist Emile Kraepelin counted errors observed in a series of simple tasks to be performed within a given timeframe – such as memorizing a sequence of numbers. Errors were taken as the most obvious sign of mental fatigue. Kraepelin also invented a system for tracking students according to their work capacity, which went hand in hand with the needs of a civilization based on productivity. And to complete the panel on mental effort metrics, in 1922, Jules Amar invented the Psychograph – a device largely inspired by Donders’ Noematachograph – that he applied to workers and soldiers, to measure and record their sensory acuity and attention.[28]
