The latest research is called: Older The brain might not not be convenient to use
According to the past experience, with the years, memory, comprehension will fail greatly, the brain will not obviously become so convenient to use as in the past. But a result of study that Amercian Psychological Association announces recently shows, experience previously might exaggerate old and feeble impact on mental work, the intersection of the elderly and far than afford to imagine decline in intelligence. This research shows, increase with age, really there are one to rise one young people's intellectual strength of heart, really have decline of certain range too more than intellectual strength of the old heart, but the range thinks old before having no us. Research approaches that this discovery adopted were different in the past - -The research before this mainly adopts the horizontal law, namely draw the conclusion through the behavior of the person investigated of different age groups at the same time, this research has adopted the longitudinal research law, namely draw the conclusion through the more same crowd's behavior in different age brackets. Seeing that the influence that two kinds of research approaches will unavoidably both be offsetted, TimothySalt Juan house doctor who presides over this research emphasizes: "When explaining result of study, realize the limitation of each kind of research approach is very important. " Dr. Salthouse has reviewed different results that different research approaches cause. The horizontal research law shows, in the key field, the elderly's ability drops by a wide margin, and longitudinal research reveal until 60 year old, ability is steady, even is improving. 1616 persons investigated in all have participated in these research, 18 the youngest years old, the largest one is over 80 years old. By a definite date, person investigated divide into into different age bracket, except person investigated of age bracket there are 87 from 80 year old to 89 year old with 10 year, the person investigated of other each age bracket has exceeded 100 people. The researcher has analyzed 5 kinds of key cognitive ability of the person investigated: Deduce, space vision, scene memory, consciousness speed and vocabulary test. Separate for two and a half years at least each time, the person investigated will accept test. Under study for action, Salthouse has considered the influence of the following fact: Namely participate in the person that tests to testing will be familiar with more and more, therefore it may be better and better to behave repeatedly. But the result of study still shows, compared with the situation that the mental decay of relevant age wants imagine small before this.
