to determine if there was behavioral evidence in the output spectra
for two different sets to respond.
An example of the we of spectral densities for examining behavioral
characteristics can be seen in figures 2 and 3 which illustrate a comparieon
of smoothed spectral densities for'two different instructions
for one highly trained subject. It rill be noted that Inatrbtione for
accuracy resulted in a considerably smoothed output. The fiducial lines
represent 2 t confidence bands arising from instrument errors in the
computations of the spectrum.
In general, the experiments were not of sufficient magnitude for an
adequate test of the psychological questions raised. On the other hand,
the form of the results indicates the fruitfulness of this method of
analysis and its logical extension to the interpretation of tracking
dat'e from the dynamic simulator.
At present the dynamic simulator has been used for a small experiment
utilizing three trained jet pilots. The data obtained, which is
in the form of responses to gust inputs, will be used to obtain certain
order of magnitude approximetions to "humen transfer functions" using The
Frenklin Institute Advanced Time Scale Analog Computer. The general
research program for the study of the human operator envisione the use
of special data reduction equipment to be constructed at The Franklin
Institute for the determination of the pertinent spectral densities and
cross spectral densities.
