Abstract: Deterministic mathematical models of nonlinear systems can giverise to complex aperiodic (chaotic) dynamics, which have been studiedby scientists in many fields. This paper presents considerations onchaotic dynamics of direct relevance to physiological psychology. Anelementary review of the onset and numerical analysing methods ofchaos is given. We took the computation experimental facts in neuralsystem as an example to show that there are more significance infinding some new statistical implements in psychology.
