Treffer: Visual perception and cognitive in aging

Modern gerontological research shows a decline in the sensory-motor reaction, deterioration of information processing and perception, as well as a reduction of mental capability with aging. One may assume that perception and informational processing capability in aging people are determined by the balance between aging and longevity processes (life extension). Unfortunately, studies on the visual perception and informational processing capability in aging are lacking. Human subjects (80 males and 90 females) belonging to the three age groups (30-39, 40-49, and 50-60 years) were examined. The visual perception and information processing were studied by a special computer test with three algorithm changes. Our research revealed that with age-related decline of perception and information processing, intensifies tension of the informational environment on older people. As a result of the negative influence of aging, the efficiency of mental activity reduces. Decrease of the visual perception and information processing capability with age triggers a compensation of the psychophysiological adaptive mechanisms with the change of an algorithm. The key mechanism consists in the increase of the stochastic organisation of information processing and change of the information processing structure into a self-finishing quest response.
