AP PSYCHOLOGY

Detailed explanation-1: -For the purpose of this textbook and chapter, we will define late adulthood from age 65 to 100 and beyond. In this chapter, we will learn how many people are in late adulthood, how that number is expected to change, and how life changes and continues to be the same as before in late adulthood.

Detailed explanation-2: -There have been many ways to categorize the ages of individuals in late adulthood. In this chapter, we will be dividing the stage into three categories: Young–old (65-84), oldest-old (85-99), and centenarians (100+) for comparison.

Detailed explanation-3: -Group 1: youngest-old (65 to 74 yr), Group 2: middle-old (75–84 yr), Group 3: oldest-old (85 or over 85 yr).

Detailed explanation-4: -The stages of adulthood examined here include: Early Adulthood (ages 22–34). Early Middle Age (ages 35–44), Late Middle Age (ages 45–64), and Late Adulthood (ages 65 and older).

Detailed explanation-5: -Aging in late adulthood profoundly affects appearance, sensation, and motor abilities. An older adult’s appearance changes as wrinkles appear and the skin becomes less elastic and thin. Small blood vessels break beneath the surface of the skin, and warts, skin tags, and age spots (liver spots) may form on the body.
