Chapter 9: Problem 5

Discuss the different theories of aging, and summarize the research to increase life expectancy.

Short Answer

Expert verified
Theories of aging can be biological, psychological, or sociological, each focusing on varying aspects of the aging process. Research on increasing life expectancy ranges from studies on calorie restriction and natural compounds like resveratrol to more advanced scientific procedures like telomere elongation and gene therapy.

Step by step solution

01

Understanding Aging Theories

Aging theories can be biological, psychological, social and integrated. Biological theories of aging are based on the physical process of aging and include theories like Free Radical Theory, Mitochondrial Theory, and Telomere Aging Theory. Psychological theories focus on the mental processes and include Disengagement Theory or Activity Theory. Sociological theories deal with social relationships, roles, and statuses of older people, for example, the Continuity Theory.
02

Summarizing Aging Theories

Discuss each of the theories in detail. Biological theories focus on the physical changes in the body as it ages, while psychological theories focus on changes in mental functions. Sociological theories, on the other hand, look at the impact of social and societal forces on aging.
03

Discussing Research on Life Extension

Research into increasing life expectancy has led to a deeper understanding of the aging process and has been primarily looking at the possibility of delaying, stopping or reversing the process of aging. This includes studies on calorie restriction, natural compounds like resveratrol, telomere elongation, gene therapy, among others.
04

Summarizing Life Extension Research

Summarize the major findings of life extension research. This should highlight the potential methods to increase life expectancy, the feasibility of these methods, and the ethical considerations associated with life extension.

Most popular questions from this chapter

Identify the learning opportunities available to older adults, and describe their value to cognitive functioning. Educational programs like Road Scholar offer learning opportunies for older adults. Many public colleges also encourage senior citizens to enroll in classes. Exercising cognitive skills may help people keep their intellectual functioning sharp in late adulthood.

Explain how memory capability changes in late adulthood. Declines in memory affect mainly episodic memories and short-term memory. Explanations of memory changes in old age have focused on environmental factors, information-processing declines, and biological factors.

Describe the challenges of determining the cause of age changes in intelligence. Because of cohort effects and other challenges, it is difficult to draw conclusions about the reasons for age changes in intelligence using cross- sectional and longitudinal studies.

Define wisdom, and describe how it is associated with age.

Summarize the effects of aging on cognitive functioning, and identify the factors which may affect it. Although some intellectual abilities gradually decline throughout adulthood, starting at around age \(25,\) others stay relatively steady. For example, research shows that although fluid intelligence declines with age, crystallized intelligence remains steady, and may even improve, in late adulthood. There is no uniform pattern of age-related intellectual changes. Factors that may affect cognitive functioning include environmental and cultural factors.
