Abstract

Research on aging has been focused mainly on how various cognitive functions decline with aging. However, the decline or damage can not explain the complex picture of cognitive changes in later life. Older adults seem to perform very well in certain tasks, and even to show better performance than younger adults. Recent cognitive control model, including emotion and motivation, can explain the inconsistent effects of aging. People used to consume a reasonable level of cognitive resources, and it seems that older adults preserve the ability to adjust the level of consumption to the optimal level in regards to their emotion and motivation. As people are getting older, they put more value on certain attributes of information that is emotionally charged, and this will, in turn, change the strategy of the allocation of cognitive resources to perform well on a given task by the old people. One of the reasons why aging research can not fully explain the asymmetric results of cognitive aging would be attributed to the fact that the usage of value-free (emotionally neutral) stimuli in laboratory settings is not quite sensitive enough to delineate the difference in strategy changes between young and old adults. Knowing that people deal their daily activities with emotionally valued information, it should be adopted a new framework that puts a high priority on emotion and motivation in cognitive aging research.
