[The importance of information load in training visual-spatial memory under distributed attention in older women.]

The activation of cognitive reserves and improved neuroplasticity of the brain, found as a result of cognitive training in the elderly, stimulate research in this direction due to the lack of consensus on the effectiveness of such an impact so far. To study the effect of information load during training of visual-spatial memory in conditions of distributed attention, the dynamics of memory and attention indicators was analyzed during ten training sessions in groups of twenty-year-old (GrY) and sixty-year-old (GrO) women. Regardless of the experimental conditions, the GrO differs from the GrY in the lower accuracy of hitting the target spatial spaced stimuli but similar indicators of attention concentration on the centrally located stimulus. An improvement in the accuracy of hitting spatially separated stimuli was found in the GrO only under relatively facilitated conditions of information selection: in the absence of distracting stimuli, while the GrY showed an increase in the efficiency of information selection during training with a greater cognitive load, i. e. with the presentation of distractors: an increase was found not only in the accuracy of getting into goal, but also concentration on the centrally presented stimulus. The results obtained indicate the need to select an individually optimal information load during cognitive training.
