A cognitive psychologist conducts a study to examine differences in cognitive functioning across stages of adulthood. He opts to

study one group of young adults ages 21-28. one group of middle-aged adults aged 41-48, and one group of older adults ages 61-

68. He finds that the young adult group outperforms both other groups on a variety of cognitive tasks and that the middle age

group outperforms the older group. He concludes that age relates to cognitive performance on these tasks.

Which of the following statements would be a valid criticism of this study's conclusion?

Explanation:

A cognitive psychologist concludes that age relates to cognitive performance on these tasks. This statement means that as a person age's its ability to perform the cognitive task declines. In the study conducted between the various age group the cognitive psychologist where able to find that the people in their middle age (i. e. between 41-48) were able to perform the cognitive task is a better way than the people in the older group. and the younger group was able to perform the cognitive task much better than the middle and the old age group.

Now their is no need for the comparison of the middle age and the old age people for performing the task because as er the conclusion the cognitive skills decline with the age.

So, the psychologist finding that that the middle age group outperforms the older group is a valid criticism to the study's conclusion
