DATA ANALYSIS OF AGE-RELATED CHANGES IN VISUAL MOTION PERCEPTION

Abstract

Many cognitive abilities decline with age, but ageing is accompanied by great variability within older population. The aim of the present study is to explore the possibility to differentiate the age-related and the individual differences in visual information processing. Two different analytical methods – mixed ANOVA and fuzzy clustering, were applied to the data of psychophysical experiments on motion direction discrimination. The results suggest that the complementary analysis based on both methods offers new opportunities to retrieve information from the psychophysical studies and to separate the differences due to age and gender from the individual differences of the participants. The proposed data analytic approach allows better understanding of the factors that caused variation in performance with age and can be used as a diagnostic tool to distinguish pathological from normal ageing.
