Human information processing in different age

The aim of investigation was to study the aging pecularities of information processing organization. 60 men and 90 women in four age groups: 30-39, 40-49, 50-59 and 60-65 were examined. The information processing was modeled by special computer test with working algorithm changes. The time and accuracy of each assignment were registered for each person. The psychophysiological mechanisms of informational processing were studied by informative mathematical methods. The results are showed that within the aging reduction of perception, processing and speed of reaction in older. As a result of the negative influence of aging shows the decline of mental activity efficiency. Aging decrease on mental capability provokes the compensation of psychophysiological mechanisms of adaptation. The main mechanism increases the psychophysiological organization stochastic and changes the type organization in informational processing to a self-finishing quest response. (Tab. 5, Ref. 22.)
