spite of the opinion that with age the reaction slows down, the researchers argue that healthy older people can learn to react faster on some of the tasks of decision-making, while maintaining the accuracy of the responses.Thus, the cognitive skills of the elderly differ slightly from young abilities.
Many people think that the slowing of the brain as a natural process of aging, however, failed to prove the scientists from Ohio University, in reality it is not.At least 70-year-old man, in some situations, it may react with the same speed as the 25-year-old.
more than ten years, scientists have studied this question by comparing the rate of mental reaction, the elderly and children.Results of the research were published in the journal Child Development.
Results reaction rate studies in children were expected: children react more slowly and less accurately than adults.As they grow, these indicators are improving.More interesting was that the neural processes in the brain of older people does not necessarily take place more slowly than in the young.Older people want to avoid any mistakes, which makes them react more slowly.It's hard enough to eliminate this habit, but with exercise possible.
study identified a link between speed of response and accuracy of response in the elderly.In previous studies, which investigated one of said parameters, the results have shown that the accuracy of the responses in the elderly suffers, and the reaction slows with age.However, in the study of both parameters reveals the relationship between them, which explains the apparent slow reaction.
results of the study showed a gradual increase in the accuracy of the responses and reduced reaction times as they grow older children from school to students.Young children, like the elderly, needed more time to decide and to answer the question.But at the same time, children are less accurate because they can not carefully analyze the information.As they get older increases the accuracy of the responses.
in adults and the elderly is not the case.When comparing the three age groups - students and senior citizens aged 60-74 and 75-90 years - the accuracy of the responses differed significantly even in the oldest age group.But the reaction time increased from group to group with increasing age of the participants.However, such a difference in the reaction rate is not necessarily associated with a general deterioration of brain function.For example, when performing simple tasks accuracy and speed of response remains unchanged up to 85-90 years of age.
Thus, age deterioration of the reaction speed and decision-making, at least relatively simple tasks, insignificant, and in many cases the elderly in the rapidity of the reaction are not inferior to even nimble kids.
