Adulthood definitions are always inconsistent and contradictory because there are different types of adulthood namely early adulthood (ages in between 30), middle adulthood (ages up to 65), and late adulthood (ages after 65)

Answer to Problem 1MM

Correct answer: By age 65, a person would be most likely to experience a cognitive decline in the ability to recall and list all the important terms and concepts in a module. Hence, option b. is the correct answer.

Explanation of Solution

Reason for correct statement:

Option a. is given as “recall and list all the important terms and concepts in a module”. At the region of the brain, the limbic region is responsible for memory, and the hippocampus region which is the part of limbic region is responsible for aging. At the age of 65, the blood–brain barrier breaks down at the beginning in the hippocampus region that further leads to cognitive decline. So at this age, a person starts to forget about the things. So at the age of 65, the person starts to recall and list all the important terms and theories in a section. Hence, option a. is the correct answer.

Reasons for incorrect statement:

Option b. is given as “select the correct definition in a multiple-choice question”. At an older age, the person is unable to memorize the theory. But to select the correct definition, the person has to memorize the theory and choose it from the given statements. Hence, option b. is incorrect.

Option c. is given as “recall their own birth date”. The memory about the own birth date is at the conscious portion of our brain. Usually, people do not forget their birth date. Hence, option c. is incorrect.

Option d. is given as, “practice a well-learned skill, such as knitting”. Due to cognitive decline, the person after the age of 65 will be unable to memorize the things, so after practice also the person is unable to do it. Hence, option d. is incorrect.

Hence, option b., c., and d. are incorrect.

Conclusion

By the age of 65, the person would be most probable to experience a cognitive decline in the ability to recall and list all the important terms and concepts in a module.
