The study shows that this development of
higher habits has already begun before the lower habits are fully
settled.
How far the special training involves at the same time a general
training which could be of advantage for other kinds of labor has not
yet been studied at all with reference to industrial technique. There
we are still completely dependent upon certain experiences in the
field of experimental pedagogy, and upon certain statistics, for
instance, in the textile industry. Many patient investigations, with
every independent group of apparatus and machines, may be necessary
before psychotechnics will be able to supply industry with reliable
advice for teaching and learning. Nor have we the least right hastily
to carry over the results from one group of movements to another. Even
where superficially a certain similarity between the technical factors
exists, the psychophysical conditions may be essentially different. In
the two cases mentioned, for instance, telegraphing and typewriting,
the chief factor seems the same, as in both cases the aim is to make
the quickest possible finger movements for purposes of signals; and
yet it is not surprising that the development of the ability from the
beginnings to the highest mastery is rather unlike, as all the
movements in telegraphing are performed with the same finger, while
in typewriting the chief trait is the organization of groups from the
impulses to all ten fingers.
