has been used as an external dynamics presented
to the adaptive system showed self-excited spiral-pattern
formation. The set of parameters of
the internal modules in contrast have been chosen
so that some modules showed self-excited pattern
formation whereas others did not form patterns
without explicit excitation by an additional signal.
The parameters’ values of the internal modules
spaned a grid around the values of the external
parameters. Each oscillator of the external array
has been coupled by means of Pyragas’ force
control to the corresponding oscillator of the
internal module as well as to that of the mirror
system. The mirror has been adapted to the
external array with respect to two parameters.
After a relatively short adaptation time the mirror
system was able to simulate where the meaning
of simulation became particularly vivid in this
case. After the modules as well as the simulus
has been decoupled from the external array the
simulus remained in a synchronous state with
the stimulus for quite a long time whereas the
internal modules desynchronized. If one now
assumes that each oscillator corresponds to a
video pixel one may speculate whether a
continuation even of a movie at least for a short
time is possible. We dare to compare a drift of
the simulus away from the reality into unrealistic
events after decoupling (i.e. sonsory deprivation
of) the cognitive system from the rest of the
world with dreaming or hallucinating. A further
speculation is the possibility to apply the system
within the fields of interactive cinema. Given
that the idea of hermeneutics holds, a further
expectation is that an adaptive system like the
one proposed above shows what is called „narrative
knowledge“. To put it simple, although
our perception is limited by spatio-temporal
locality we nevertheless get an impression of the
whole only by the perception of single spatiotemporal
extracts (scenes) that are glued together.
This „connexionism“ leaves much space for
interpretation and has some similarity with the
„binding problem“ in neuro-physiology [28]. To
enhance the proposed device for the usage in
future cinema is a big but exciting challenge.
We mention in passing, that cognition cannot
work without storage which, of course, also holds
for the proposed cognitive system. It is
straightforward, however, to regard the pool of
internal modules as a memory since the mirror
system can be fed into the pool or even treated
as an internal pool member from the very
beginning. Mutual force control applied to the
internal modules lead to a self-modifying
property. Each external stimulation leaves an
internal pool of modules after the adaptation that
can undergo internal control and modification

processes that, with a grain of salt, may even
introduce creativity escpecially after
stochasticity is added to a certain degree.
Conclusions
We repeat our statement from above that we
regard cognition and perception as a continuous
alternation between stimulation and simulation.
As a more allegoric statement we add that the
„interpretation“ takes place on the „interface“
between the two specifications of
complementarity that are tighly entangled. We
are well aware that semantical and consciousness
related aspects as interpretation and creativity
are much more profound than we suggest when
comparing with the functioning of our adaptive
system. We therefore emphasize once more that
we speak of an enormous potentiality that lies
in the design of the proposed system which is at
least true for technical applications. Insights to
human social behavior and cognition may be
gained in a multi-agent realization of the
proposed cognitive system. We are confident
that new properties that are much closer to human
cognition arise when several of the adaptive
systems are coupled.
