[Aging-Induced Reorganization of Association Between Intelligence and Characteristics of Attention and Memory].

Abstract

The relationships between intelligence and indicators of attention systems functions, and recogni- tion of remembered verbal and figural stimuli, as well as the lateral characteristics of verbal memory in older age (64.5 ± 6.3 years, n = 83; 43 women) and in young group (22.0 ± 4.5 years,.n 133; 83 women) have been studied. It was found that the rate of information selection in conflict condi- tions is a. predictor of the level of intelligence, regardless of age. In old age a higher level of intelligence corresponds to shorter time of executive control system while in the young people accurate significant relations between intelligence and functions of attention systems are not found. In the analysis of memory, aging-independent a positive contribution to the intelligence have the words addressed to the left hemisphere; additionally in the young age the contribution of verbal memory when words addressing the right hemisphere, and in the elderly the retrieval of verbal and figural stimuli. Gender specificity in age-associated reorganization of attention and memory as predictors of intelligence was revealed, i.e. age-related changes were more pronounced in men.
