CHAPTER 1
Theories of Aging and Later Life Development
A person is not a problem to be solved, but a mystery in which to dwell.
âDaniel P. Sulmasy (2002, after Marcel, 1949)
Old age, especially when it has enjoyed honors, has an influence worth all the pleasures of youth put together.
âMarcus Tullius Cicero (106â43 BCE)
CHAPTER OVERVIEW
In this chapter, you will learn some basic information about the major theories of aging and later life development. You will learn about implicit theories of aging. You also will learn two perspectives on aging from two very different culturesâa classical point of view from the ancient city-state of Athens and a Hindu outlook from India. Finally, you will learn a number of modern and contemporary theories of aging, including those of Carl Jung, Erik Erikson, Paul Baltes, Johannes Schroots, and others.
The first time I, as a clinician-in-training, sat down with an older adult clientâan 80-year-old who was recovering from a strokeâI thought to myself, âWhat do I really know about growing old?â I was lucky enough to have spent cherished time with my grandparents and to have taken wonderful courses in aging and psychology, but I did not have an experiential understanding of aging. The longer I thought about this, the more I realized that what I did have was a personal theory of aging. I did not label it as a theory per se; rather, I thought of it as a set of beliefs. As I reflected on my theory, I came to understand that my personality; the culture in which I live; my age; my education; my experiences in childhood, adolescence, and adulthood; and a number of other factors influenced my theory.
I came to believe that each of us has a personal theory of aging and later life development. I have one, you have one, and older clients have one. We may not have articulated our theories, but we have them. Like those that influence my theory, many factors influence your theory and older clientsâ theories: personality, culture, gender, age, cohort, lived experience, and so forth. These factors affect beliefs about development over the life span and into old age. Furthermore, as we change over time, so do our theories of aging and later life development.
You might be thinking, âWhat relevance does a theory of aging have in my day-to-day life or that of older clients?â I argue that theories of aging do matter. What you believe about aging influences how you perceive and interact with older clients. Furthermore, older clientsâ beliefs about aging influence how they perceive themselves and how they interact with others. Whether one is counselor or client, oneâs theory of aging influences oneâs perceptions and how one lives oneâs day-to-day life.
Aging, as an area of study, is unique in that there is no single overarching theory. In other words, there is no unified theory of life span development and aging. There are many different theoriesâsome of them biomedical, others sociological, psychological, philosophical, economic, or spiritual. In this chapter, we will look at two philosophical-spiritual perspectives, as well as major psychosocial theories. We will explore how they are similar to and how they differ from one another, focusing particularly on those factors most relevant to counseling.
Older people have sets of beliefs about how personal attributes change over the life course, and they use these beliefs to construct stories of what they were like when they were younger (McFarland, Ross, & Giltrow, 1992). These sets of beliefs are implicit theories of aging. That is, each of us has a set of beliefs, even if we do not explicitly articulate it to others or even to ourselves.
Attributes found in these implicit theories take one of three forms: attributes that are perceived as increasing with age (e.g., understanding, affection, life satisfaction, pride, or physical discomfort), attributes that are perceived as decreasing with age (e.g., activity level, ruggedness, or the ability to remember names or phone numbers), or attributes that are perceived as neither increasing nor decreasing with age (e.g., involvement in politics, mood swings, or the importance of being attractive) (McFarland et al., 1992). An older adult may believe that athletic ability decreases with age, happiness decreases with age, and assertiveness increases with age. This is one implicit theory of aging. Another older adult may believe that memory decreases with age but that wisdom increases with age and that common sense stays the same. This is another implicit theory of aging. An individualâs set of beliefs compose, then, his or her implicit theory of aging.
Older adultsâ remembrance of attributes that they believe increase with age are biased, in that they recall themselves as possessing less of a particular attribute when younger than is actually possessed by younger adults. Likewise, older adultsâ remembrance of attributes that they believe decrease with age are biased in that they recall themselves as possessing more of a particular attribute when younger than is actually possessed by younger adults (McFarland et al., 1992). This suggests either that older adults have implicit theories of aging that are biasedâin that the theories demand more change in attributes than what is actually experiencedâor that the theories are not biased but older adultsâ current assessments of changes in the attribute are (McFarland et al., 1992). What is clear is that older adultsâ memories are influenced by their intrinsic theories of aging, namely, in the changes experienced as one gets older, whether the changes are positive or negative, and independent of how self-serving is the memory (McFarland et al., 1992).
Aging is âthe transformation of the human organism after the age of physical maturity ⌠so that the probability of survival constantly decreases and there are regular transformations in appearance, behavior, experience, and social rolesâ (Birren, 1988, p. 159). This means that upon birth, and for a period of years, we develop toward sexual maturity, reaching an age at which we are most successful at sexual reproduction. After this age begins a period in which we, at an increasing rate, are more likely to die and a period in which changes continue to occur in how we look, how we act, what we experience, and the roles we are given or that we take in our families and culture. One thing is as certain as our birth: If we are so lucky, we shall mature, grow into old age, and die.
What follows is a broad overview of theories of aging and later life development. We will start with two diverse theoretical foundations: that of the city-state of ancient Athens expressed in Platoâs perspective on aging and that of India expressed in the Hindu life stage concept of ashrama. We then will explore modern theories of aging, including Carl Jungâs perspective, Havinghurstâs activity theory, Eriksonâs eight stages of psychosocial development, Cumming and Henryâs disengagement theory, and Neugartenâs perspective on personality and successful aging. Finally, we will address some of the major contemporary theories, including Baltes and associatesâ theory of selective optimization with compensation, Salthouseâs resource-reduction theory, Costa and McCraeâs personality trait model, Levinsonâs personality development theory, Tornstamâs gerotranscendence theory, Schrootsâs gerodynamics theory, Atchelyâs continuity theory, and Rowe and Kahnâs theory of successful aging. Though not without their critics, these theories will help you broaden and deepen your understanding of later life and aging.
As we address the theories, consider the degree to which each of them has relevance to clients or is helpful in conceptualizing clientsâ challenges or in developing therapeutic interventions. Ask yourself, âAre Platoâs theory or Hindu ashrama theory relevant to my clients? Are either of these theories helpful to them in conceptualizing their challenges or in developing more adaptive responses? Does gerotranscendence theory have relevance to me? Is it helpful to me in conceptualizing my clientsâ challenges or in developing therapeutic interventions?â
ANCIENT FOUNDATIONS
We will begin by discussing as examples of the diversity of theories of life span development and aging a theory based on an ancient Western traditionâa classical Athenian perspective on aging presented by Platoâand a theory based on an Eastern traditionâa theory of life span development that evolved in Indiaâs Hindu tradition. These two perspectives are offered as example theories of aging. You will find other early theories in the writings of the ancient Romans, Chinese, Persians, and other civilizations.
Platoâs Theory of Aging
Plato explicated a theory of aging in at least three of his major worksâRepublic, Apology, and Critoâand in doing so anticipated three major issues in theories of aging: dialectic between theories, the life review, and the nature of wisdom (McKee & Barber, 2001) (see Table 1.1).
TABLE 1.1 Platoâs Theory of Aging
Issue | Description |
Dialectic between theories | The dynamic tension between old age as a time of activity-continuity and old age as a time of disengagement-gerotranscendence |
Life review | Retrospective evaluation of life prompted by temporal movement toward death |
Nature of wisdom | Cognitive, affective, and volitional dimensions of an older person that are useful in responding to lifeâs problems |

Dialectic Between Theories. A theory of aging can be conceptualized as being either an activity-continuity theory or a disengagement-gerotranscendence theory (McKee & Barber, 2001). An activity-continuity theory of aging is one that proposes that in late life, adults continue to seek out those activities, relationships, and values that were of importance to them in midlife (McKee & Barber, 2001). Any theory with this viewpoint fundamentally proposes that we think, feel, and do in late life that which we think, feel, and do in midlife unless something (such as illness) interferes with it. It is a belief in continuity in adulthood. A disengagement-gerotranscendence theory of aging is one that proposes that in late life adults develop a perspective different from what they had in midlife. Furthermore, this different perspective is marked by a lesser interest in the beliefs, feelings, and activities common in midlife and a greater interest in looking inward and considering oneâs relationship to the transcendent (McKee & Barber, 2001). Both of these theoretical orientations are present in Platoâs writings.
In the Republic, Plato describes an interaction in which Socrates asks an old man, Cephalus, the secret of happiness in late life. Cephalus states that happiness in late life is found in qualities that allow one to detach from the values of youth and midlife (especially those of material gain) and âto transcend the many painful aspects of age,â especially those of physical decline (McKee & Barber, 2001, p. 94). Furthermore, Plato reflects on several concepts found in disengagement-gerotranscendence theory (discussed below): a movement from materialism to transcendentalism (in the allegory of the cave, represented by the desire to escape from darkness into the light), âidentification with prior generationsâ (in stories of Socratesâ respect for the customs and laws of civil society), âresponsibility for future generationsâ (in the allegory of the cave, the wise oneâs return to the cave as mentor), and a decreased fear of death (in stories of Socratesâ gracious acceptance of the inevitability of death) (McKee & Barber, 2001, p. 97). Through these stories, Plato appears to be at the disengagement-gerotranscendence end of the spectrum.
Yet Plato does not stop there. He considers whether older adults who want to disengage have a responsibility not to do so and to remain actively engaged (McKee & Barber, 2001). In the allegory of the cave, Plato comes to the conclusion that older adults have a moral obligation to return to the cave where others remain, to stay engaged, and to share the pains and joys of the younger generations (McKee & Barber, 2001). Plato, in his telling of the story of Socratesâ trial, suggests that continuity of thoughts, feelings, and behaviors is present in late life, even in the face of severe circumstances, including the prospect of death (McKee & Barber, 2001). These stories reflect an activity-continuity perspective. What are we to conclude? For Plato, aging may be a time of activity-continuity or of disengagement-gerotranscendence or both. This suggests the possibility that, in terms of theories of aging, what is needed today is an integration of theories from each end of the spectrum (McKee & Barber, 2001).1
Life Review. Robert Butler (1963, cited in McKee & Barber, 2001) developed the concept of life review2 to describe why older adults reminisce. He posited that elders review their lives in order to evaluate the decisions they made and the relationships they had over their life course (McKee & Barber, 2001). Butler suggested that older adults reminisce more because they are closer to death, that in reminiscing they may change their judgments, and that life review varies from one person to another and varies over time even within the same person (McKee & Barber, 2001). Plato tells many stories that revolve around life review. In one story, Cephalus not only recounts his past actions and considerations but also analyzes them, eschewing a romanticized nostalgia of the past and emphasizing a âretrospective evaluationâ prompted by his realization of the âreality of deathâ (McKee & Barber, 2001, p. 99). In another story, Socrates, during his trial, tells the jury about his life, detailing its major events and insightsâinsights that are accessible only to the old (McKee & Barber, 2001). To Plato, life review was a common phenomenon of late life and even more so a process that produced âknowledge and understandingâ (McKee & Barber, 2001, p. 100).
Nature of Wisdom. Plato explored the nature of wisdom, a central consideration in many theories of aging (McKee & Barber, 2001). Plato portrayed Socrates as the âwise elderâ (McKee & Barber, 2001, p. 100). He believed that wisdom comprised âcognitive, affective, and volitionalâ (i.e., thinking, feeling, and free choice) dimensions (McKee & Barber, 2001, p. 100). In the Apology, Socrates describes wisdom in its affective element and also its cognitive element. In the Republic, the...
