Document Summary

Health, illness and optimal aging: biological and psychosocial perspectives. Psychosocial gerontologists focus on describing what happens cognitively, emotionally and socially as we age, with a view toward identifying factors that promote positive aging or increase the risk of negative aging. It is important to recognize that aging is not necessarily associated with unmitigated pain and suffering and that older adults can enjoy good physical and mental health and be cognitively intact. Gerontology is unique among the scientific disciplines in that, since its inception, it has recognized that interdisciplinary endeavours are required for understanding the aging process. Biogerontology has greatly increased our understanding of the genetic and cellular mechanisms of aging, but the disciplines of psychology, sociology, and anthropology are also essential for understanding both the process and ramifications of aging. In epidemiology and the social sciences, findings may vary across time, and accepted results that are true for one cohort may not hold for another.

Related Questions

1) Describe the nature of health and illness using both the biomedical model and the biopsychosocial model. Contrast the models including both the benefits and liabilities of each model. Be sure to include relevant research and examples. 2) Discuss methods of research in health psychology. What methods do health researchers employ, and what is the purpose of this research? Which methods are superior and why? Why is it that all health topics cannot be researched the same way? Which methods are appropriate for which types of questions? 3) Select two of the following systems: immune system, nervous system, endocrine system, cardiovascular system, digestive system, reproductive system, or cardiovascular system. Discuss how these two systems interact with each other in order to maintain health. Discuss the factors that can negatively influence each of the two systems to produce illness.

QUESTION 26

Age 65 has come to be considered the onset of old age in the U.S. because:

	a.	This is when most older adults find their abilities diminishing
	b.	At age 65, physical appearance makes it evident that a person is old
	c.	This is the age identified in Social Security and Medicare at the time these were enacted

QUESTION 27

The concept of "dependency ratios" has been criticized because:

		Individual differences in needs as well as differences in aging and activity choices make it difficult to ascertain which generation depends on which other generations.
		Very few older adults ever rely on younger individuals for support and assistance
		The most dependent generation may well be young adults
		It is common knowledge that older adults are dependent on younger individuals

Bookmark Question 1 Which of the following is the best example of a positive externality? A car company lays off 10,000 employees in order to cut costs. An individual drives a large SUV, which increases the amount of greenhouse gases in the atmosphere. An individual smokes in a restaurant, which bothers other patrons. A child is vaccinated against a disease, which reduces the probability that other children will catch the disease. 4 points Question 2 As a result of a negative externality, the market equilibrium quantity is too ______ compared to the socially optimal quantity. As a result of a positive externality, the market equilibrium quantity is too ______ compared to the socially optimal quantity. high; high. low; low. high; low. low; high. 4 points Question 3 Based on the diagram below, the deadweight loss area associated with the market equilibrium equals: Week06_graph1.jpg $10 $50 $80 $1,000 4 points Question 4 A firm's accounting profit is given by total revenue: less implicit costs. less explicit costs. less economic profit. less implicit and explicit costs. 4 points Question 5 Suppose an activity has a private cost equal to $30 and a private benefit equal to $30. The associated social cost equals $35 and the social benefit equals $30. Which of the following statements is true about this activity? There is a negative externality associated with this activity but not a positive externality. There is a positive externality associated with this activity but not a negative externality. There is both a positive and a negative externality associated with this activity. There is neither a positive nor a negative externality associated with this activity. 4 points Question 6 The Coase Theorem implies that: the efficient level of an externality is generally zero. private individuals living in market economies should not be concerned with externalities. government intervention is not always needed to arrive at the efficient level of an externality. government laws are unnecessary. 4 points Question 7 An industry in which a small number of large firms sell products that are either close or perfect substitutes is: perfectly competitive. monopolistically competitive. an oligopoly. a monopoly. 4 points Question 8 When a negative externality is present in a market: a tax can increase the level of economic surplus. the social benefits are greater than the private benefits. there is generally too little of the good produced by private markets. the government should ensure that there are zero external costs associated in all markets. 4 points Question 9 In the presence of a positive externality, the government can arrive at the socially optimal output level by: paying producers a subsidy equal to the amount of social benefits associated with the activity. charging producers a tax equal to the amount of social costs associated with the activity. paying producers a subsidy equal to the amount of external benefits associated with the activity. charging producers a tax equal to the amount of external costs associated with the activity. 4 points Question 10 The tragedy of the commons is that: too few individuals have access to high quality healthcare. common people overconsume public goods. the quality of life for lower income people is generally lower than that of higher income people. a resource with no price tends to be exploited until its marginal benefit falls to zero. 4 points Question 11 One potential remedy to the tragedy of the commons is to: never allow a single individual to consume more than one percent of the common resource. criminalize the usage of common resources. allow individuals to use a common resource as long as they receive some benefit from doing so. place a common resource under private ownership. 4 points Question 12 As a result of a positional externality: contestants have a tendency to invest in a series of mutually offsetting investments in performance enhancement. there is generally an underinvestment in performance enhancement. the market price of performance enhancement materials is too high. the quality of performance in competitive situations is lower than the socially optimal level. 4 points Question 13 Which of the following statements is true regarding health insurance? Economics shows that all health related procedures should be free to individuals because the health of an individual is priceless. Total economic surplus would be larger if individuals faced an incentive to only use services when the benefit exceeds their costs. Health maintenance organizations provide an incentive for doctors to prescribe expensive nonessential services. First dollar insurance coverage has likely had very little to do with rising healthcare expenditures since World War II. 4 points Question 14 A strategy that yields a higher payoff no matter what the other players in the game choose is known as a: prisoner's strategy. dominated strategy. dominant strategy. Nash strategy.
