4.4 Adulthood

158

The unfolding of our lives continues across the life span. It is, however, more difficult to generalize about adulthood stages than about life’s early years. If you know that James is a 1-year-old and Jamal is a 10-year-old, you could say a great deal about each child. Not so with adults who differ by a similar number of years. The boss may be 30 or 60; the marathon runner may be 20 or 50; the 19-year-old may be a parent who supports a child or a child who receives an allowance. Yet our life courses are in some ways similar. Physically, cognitively, and especially socially, we differ at age 50 from our 25-year-old selves. In the discussion that follows, we recognize these differences and use three terms: early adulthood (roughly twenties and thirties), middle adulthood (to age 65), and late adulthood (the years after 65). Within each of these stages, people will vary widely in physical, psychological, and social development.

How old does a person have to be before you think of him or her as old? Depends on who you ask. For 18- to 29-year-olds, 67 was old. For those 60 and over, old was 76 (Yankelovich, 1995).

Physical Development

4-16 What physical changes occur during middle and late adulthood?

Like the declining daylight after the summer solstice, our physical abilities—muscular strength, reaction time, sensory keenness, and cardiac output—all begin an almost imperceptible decline in our mid-twenties. Athletes are often the first to notice. World-class sprinters and swimmers peak by their early twenties. Baseball players peak at about age 27—with 60 percent of Most Valuable Player awardees since 1985 coming ±2 years of that (Silver, 2012). Women—who mature earlier than men—peak earlier. But most of us—especially those of us whose daily lives do not require top physical performance—hardly perceive the early signs of decline.

“I am still learning.”

Physical Changes in Middle Adulthood

Athletes over age 40 know all too well that physical decline gradually accelerates. During early and middle adulthood, physical vigor has less to do with age than with a person’s health and exercise habits. Many of today’s physically fit 50-year-olds run 4 miles with ease, while sedentary 25-year-olds find themselves huffing and puffing up two flights of stairs.

menopause the time of natural cessation of menstruation; also refers to the biological changes a woman experiences as her ability to reproduce declines.

Aging also brings a gradual decline in fertility, especially for women. For a 35- to 39-year-old woman, the chances of getting pregnant after a single act of intercourse are only half those of a woman 19 to 26 (Dunson et al., 2002). Men experience a gradual decline in sperm count, testosterone level, and speed of erection and ejaculation. Women experience menopause, as menstrual cycles end, usually within a few years of age 50. Expectations and attitudes influence the emotional impact of this event. Is it a sign of lost femininity and growing old, or liberation from menstrual periods and fears of pregnancy? For men, too, expectations can influence perceptions. Some experience distress related to a perception of declining virility and physical capacities, but most age without such problems.

With age, sexual activity lessens. Nevertheless, most men and women remain capable of satisfying sexual activity, and most express satisfaction with their sex life. This was true of 70 percent of Canadians surveyed (ages 40 to 64) and 75 percent of Finns (ages 65 to 74) (Kontula & Haavio-Mannila, 2009; Wright, 2006). In another survey, 75 percent of respondents reported being sexually active into their eighties (Schick et al., 2010). And in an American Association of Retired Persons sexuality survey, it was not until age 75 or older that most women and nearly half of men reported little sexual desire (DeLamater, 2012; DeLamater & Sill, 2005). As Alex Comfort (1992, p. 240) jested, “The things that stop you having sex with age are exactly the same as those that stop you riding a bicycle (bad health, thinking it looks silly, no bicycle).”

Physical Changes in Late Adulthood

Is old age “more to be feared than death” (Juvenal, The Satires)? Or is life “most delightful when it is on the downward slope” (Seneca, Epistulae ad Lucilium)? What is it like to grow old?

SENSORY ABILITIES, STRENGTH, AND STAMINA Although physical decline begins in early adulthood, we are not usually acutely aware of it until later in life, when the stairs get steeper, the print gets smaller, and other people seem to mumble more. Muscle strength, reaction time, and stamina diminish in late adulthood. As a lifelong basketball player, I [DM] find myself increasingly not racing for that loose ball. But even diminished vigor is sufficient for normal activities.

With age, visual sharpness diminishes, as does distance perception and adaptation to light-level changes. The eye’s pupil shrinks and its lens becomes less transparent, reducing the amount of light reaching the retina: A 65-year-old retina receives only about one-third as much light as its 20-year-old counterpart (Kline & Schieber, 1985). Thus, to see as well as a 20-year-old when reading or driving, a 65-year-old needs three times as much light—a reason for buying cars with untinted windshields. This also explains why older people sometimes ask younger people, “Don’t you need better light for reading?”

The senses of smell and hearing also diminish. In Wales, teens’ loitering around a convenience store has been discouraged by a device that emits an aversive high-pitched sound almost no one over 30 can hear (Lyall, 2005).

Most stairway falls taken by older people occur on the top step, precisely where the person typically descends from a window-lit hallway into the darker stairwell (Fozard & Popkin, 1978). Our knowledge of aging could be used to design environments that would reduce such accidents (National Research Council, 1990).

HEALTH As people age, they care less about what their bodies look like and more about how their bodies function. For those growing older, there is both bad and good news about health. The bad news: The body’s disease-fighting immune system weakens, making older adults more susceptible to life-threatening ailments such as cancer and pneumonia. The good news: Thanks partly to a lifetime’s accumulation of antibodies, people over 65 suffer fewer short-term ailments, such as common flu and cold viruses. One study found they were half as likely as 20-year-olds and one-fifth as likely as preschoolers to suffer upper respiratory flu each year (National Center for Health Statistics, 1990).

THE AGING BRAIN Up to the teen years, we process information with greater and greater speed (Fry & Hale, 1996; Kail, 1991). But compared with teens and young adults, older people take a bit more time to react, to solve perceptual puzzles, even to remember names (Bashore et al., 1997; Verhaeghen & Salthouse, 1997). The neural processing lag is greatest on complex tasks (Cerella, 1985; Poon, 1987). At video games, most 70-year-olds are no match for a 20-year-old.

Slower neural processing combined with diminished sensory abilities can increase accident risks. As FIGURE 4.18 indicates, fatal accident rates per mile driven increase sharply after age 75. By age 85, they exceed the 16-year-old level. Older drivers appear to focus well on the road ahead, but attend less to vehicles approaching from the side (Pollatsek et al., 2012). Nevertheless, because older people drive less, they account for fewer than 10 percent of crashes (Coughlin et al., 2004).

image
Figure 4.18: FIGURE 4.18 Age and driver fatalities Slowing reactions contribute to increased accident risks among those 75 and older, and their greater fragility increases their risk of death when accidents happen (NHTSA, 2000). Would you favor driver exams based on performance, not age, to screen out those whose slow reactions or sensory impairments indicate accident risk?

Brain regions important to memory begin to atrophy during aging (Fraser et al., 2015; Schacter, 1996). The blood-brain barrier also breaks down beginning in the hippocampus, which furthers cognitive decline (Montagne et al., 2015). No wonder adults, after taking a memory test, feel older. “[It’s like] aging 5 years in 5 minutes,” jested one research report (Hughes et al., 2013). In early adulthood, a small, gradual net loss of brain cells begins, contributing by age 80 to a brain-weight reduction of 5 percent or so. Earlier, we noted that late-maturing frontal lobes help account for teen impulsivity. Late in life, some of that impulsiveness seems to return as inhibition-controlling frontal lobes begin to atrophy (von Hippel, 2007). This helps explain older people’s occasional blunt questions and comments (“Have you put on weight?”). But good news: The aging brain is plastic, and partly compensates for what it loses by recruiting and reorganizing neural networks (Park & McDonough, 2013). During memory tasks, for example, the left frontal lobes are especially active in young adult brains, while older adult brains use both left and right frontal lobes.

EXERCISE AND AGING Exercise helps counteract some effects of aging. Physical exercise not only enhances muscles, bones, and energy and helps to prevent obesity and heart disease, it also stimulates brain cell development and neural connections, thanks perhaps to increased oxygen and nutrient flow (Erickson et al., 2013; Fleischman et al., 2015; Pereira et al., 2007). Exercise aids memory by stimulating the development of neural connections and by promoting neurogenesis, the birth of new hippocampus nerve cells. And it increases the cellular mitochondria that help power both muscles and brain cells (Steiner et al., 2011).

Sedentary older adults randomly assigned to aerobic exercise programs exhibit enhanced memory, sharpened judgment, and reduced risk of significant cognitive decline (DeFina et al., 2013; Liang et al., 2010; Nagamatsu et al., 2013). Exercise also helps maintain the telomeres (Leslie, 2011). These tips of chromosomes wear down with age, much as the end of a shoelace frays. Telomere wear and tear is accelerated by smoking, obesity, and stress. Children who suffer frequent abuse or bullying exhibit shortened telomeres as biological scars (Shalev et al., 2013). As telomeres shorten, aging cells may die without being replaced by perfect genetic replicas (Epel, 2009).

The message is clear: We are more likely to rust from disuse than to wear out from overuse. Fit bodies support fit minds.

Cognitive Development

Aging and Memory

4-17 How does memory change with age?

Among the most intriguing developmental psychology questions is whether adult cognitive abilities, such as memory, intelligence, and creativity, parallel the gradually accelerating decline of physical abilities.

As we age, we remember some things well. Looking back in later life, adults asked to recall the one or two most important events over the last half-century tend to name events from their teens or twenties (Conway et al., 2005; Rubin et al., 1998). They also display this “reminiscence bump” when asked to name their all-time favorite music, movies, and athletes (Janssen et al., 2011). Whatever people experience around this time of life—the Vietnam War, the 9/11 terrorist attacks, the election of the first Black U.S. president—becomes pivotal (Pillemer, 1998; Schuman & Scott, 1989). Our teens and twenties hold so many memorable “firsts”—first kiss, first job, first day at college or university, first meeting in-laws.

Early adulthood is indeed a peak time for some types of learning and remembering. In one test of recall, people watched video clips as 14 strangers said their names, using a common format: “Hi, I’m Larry” (Crook & West, 1990). Then those strangers reappeared and gave additional details. For example, they said, “I’m from Philadelphia,” providing more visual and voice cues for remembering the person’s name. As FIGURE 4.19 shows, after a second and third replay of the introductions, everyone remembered more names, but younger adults consistently surpassed older adults. How well older people remember depends in part on the task. In another experiment, when asked to recognize 24 words they had earlier tried to memorize, people showed only a minimal decline in memory. When asked to recall that information without clues, however, the decline was greater (FIGURE 4.20).

image
Figure 4.20: FIGURE 4.20 Recall and recognition in adulthood In this experiment, the ability to recall new information declined during early and middle adulthood, but the ability to recognize new information did not. (Data from Schonfield & Robertson, 1966.)

In our capacity to learn and remember, as in other areas of development, we show individual differences. Younger adults vary in their abilities to learn and remember, but 70-year-olds vary much more. “Differences between the most and least able 70-year-olds become much greater than between the most and least able 50-year-olds,” reports Oxford researcher Patrick Rabbitt (2006). Some 70-year-olds perform below nearly all 20-year-olds; other 70-year-olds match or outdo the average 20-year-old.

No matter how quick or slow we are, remembering seems also to depend on the type of information we are trying to retrieve. If the information is meaningless—nonsense syllables or unimportant events—then the older we are, the more errors we are likely to make. If the information is meaningful, older people’s rich web of existing knowledge will help them to hold it. But they may take longer than younger adults to produce the words and things they know. Older adults also more often experience tip-of-the-tongue memories (Ossher et al., 2012). Quick-thinking game show winners are usually young or middle-aged adults (Burke & Shafto, 2004).

Sustaining Mental Abilities

Psychologists who study the aging mind debate whether “brain fitness” computer training programs can build mental muscles and stave off cognitive decline. Our brains remain plastic throughout life (Gutchess, 2014). So, can exercising our brains on a “cognitive treadmill”—with memory, visual tracking, and problem-solving exercises—avert losing our minds? “At every point in life, the brain’s natural plasticity gives us the ability to improve . . . function,” said one neuroscientist-entrepreneur (Merzenich, 2007). One 5-year study of nearly 3000 people found that 10 one-hour cognitive training sessions, with follow-up booster sessions, led to improved cognitive scores on tests related to their training (Boron et al., 2007; Willis et al., 2006). Other studies with children and adults also found that brain-training exercises can sharpen the mind (Anguera et al., 2013; Jonides et al., 2012; Karr et al., 2014).

162

Based on such findings, some computer game makers are marketing daily brain-exercise programs for older adults. But other researchers, after reviewing all the available studies, advise caution (Melby-Lervåg & Hulme, 2013; Redick et al., 2013; Salthouse, 2010; Shipstead et al., 2012a,b). The available evidence, they argue, suggests that brain training can produce short-term gains, but mostly on the trained tasks and not for cognitive ability in general (Berkman et al., 2014; Harrison et al., 2013; Karbach & Verhaeghen, 2014). A British study of 11,430 people, who for 6 weeks either completed brain training activities or a control task, confirmed the limited benefits. Although the training improved the practiced skills, it did not boost overall cognitive fitness (Owen et al., 2010). “Play a video game and you’ll get better at that video game, and maybe at very similar video games,” observes researcher David Hambrick (2014), but not at driving a car or filling out your tax return.

longitudinal study research in which the same people are restudied and retested over a long period.

Chapter 9 explores another dimension of cognitive development: intelligence. As we will see, cross-sectional studies (comparing people of different ages) and longitudinal studies (restudying the same people over time) have identified mental abilities that do and do not change as people age. Age is less a predictor of memory and intelligence than is proximity to death. Tell us whether someone is 8 months or 8 years from a natural death and, regardless of age, you’ve given us a clue to that person’s mental ability. In the last three or four years of life and especially as death approaches, cognitive decline typically accelerates, and negative feelings increase (Vogel et al., 2013; Wilson et al., 2007). Researchers call this near-death drop terminal decline (Backman & MacDonald, 2006). As death approaches, our goals also shift. We’re driven less to learn and more to connect socially (Carstensen, 2011).

Social Development

4-18 What themes and influences mark our social journey from early adulthood to death?

Many differences between younger and older adults are created by significant life events. A new job means new relationships, new expectations, and new demands. Marriage brings the joy of intimacy and the stress of merging two lives. The three years surrounding the birth of a child bring increased life satisfaction for most parents (Dyrdal & Lucas, 2011). The death of a loved one creates an irreplaceable loss. Do these adult life events shape a sequence of life changes?

Adulthood’s Ages and Stages

As people enter their forties, they undergo a transition to middle adulthood, a time when they realize that life will soon be mostly behind instead of ahead of them. Some psychologists have argued that for many the midlife transition is a crisis, a time of great struggle, regret, or even feeling struck down by life. The popular image of the midlife crisis is an early-forties man who forsakes his family for a younger girlfriend and a hot sports car. But the fact—reported by large samples of people—is that unhappiness, job dissatisfaction, marital dissatisfaction, divorce, anxiety, and suicide do not surge during the early forties (Hunter & Sundel, 1989; Mroczek & Kolarz, 1998). Divorce, for example, is most common among those in their twenties, suicide among those in their seventies and eighties. One study of emotional instability in nearly 10,000 men and women found “not the slightest evidence” that distress peaks anywhere in the midlife age range (McCrae & Costa, 1990).

For the 1 in 4 adults who report experiencing a life crisis, the trigger is not age but a major event, such as illness, divorce, or job loss (Lachman, 2004). Some middle-aged adults describe themselves as a “sandwich generation,” simultaneously supporting their aging parents and their emerging adult children or grandchildren (Riley & Bowen, 2005).

social clock the culturally preferred timing of social events such as marriage, parenthood, and retirement.

Life events trigger transitions to new life stages at varying ages. The social clock—the definition of “the right time” to leave home, get a job, marry, have children, or retire—varies from era to era and culture to culture. The once-rigid sequence has loosened; the social clock still ticks, but people feel freer about being out of sync with it.

Even chance events can have lasting significance, by deflecting us down one road rather than another. Albert Bandura (1982, 2005) recalls the ironic true story of a book editor who came to one of Bandura’s lectures on the “Psychology of Chance Encounters and Life Paths”—and ended up marrying the woman who happened to sit next to him. The sequence that led to my [DM] authoring this book (which was not my idea) began with my being seated near, and getting to know, a distinguished colleague at an international conference. The road to my [ND] co-authoring this book began in a similar, unplanned manner. DM stumbled on an article about my professional life (which was also not my idea) and invited me to visit his college. We began a conversation that resulted in our collaboration. Chance events can change our lives.

“The important events of a person’s life are the products of chains of highly improbable occurrences.”

Joseph Traub, “Traub’s Law,” 2003

Adulthood’s Commitments

Two basic aspects of our lives dominate adulthood. Erik Erikson called them intimacy (forming close relationships) and generativity (being productive and supporting future generations). Sigmund Freud (1935/1960) put this more simply: The healthy adult, he said, is one who can love and work.

LOVE We typically flirt, fall in love, and commit—one person at a time. “Pair-bonding is a trademark of the human animal,” observed anthropologist Helen Fisher (1993). From an evolutionary perspective, relatively monogamous pairing makes sense: Parents who cooperated to nurture their children to maturity were more likely to have their genes passed along to posterity than were parents who didn’t.

Adult bonds of love are most satisfying and enduring when marked by a similarity of interests and values, a sharing of emotional and material support, and intimate self-disclosure. There also appears to be “vow power.” Straight and gay romantic relationships sealed with commitment—via marriage or civil union vows—more often endure (Balsam et al., 2008; Rosenfeld, 2014). Such bonds are especially likely to last when couples marry after age 20 and are well educated. Compared with their counterparts of 30 years ago, people in Western countries are better educated and marrying later. These trends may help explain why the American divorce rate, which surged from 1960 to 1980, has since leveled off and even slightly declined in some areas (Schoen & Canudas-Romo, 2006). If anything, our standards have risen over the years, though. We now hope not only for an enduring bond, but also for a mate who is a wage earner, caregiver, intimate friend, and warm and responsive lover (Finkel et al., 2015).

164

Historically, couples have met at school, on the job, through family, or, especially, through friends. Since the advent of the Internet, such matchmaking has been supplemented by a striking rise in couples who meet online—as have nearly a quarter of heterosexual couples and some two-thirds of same-sex couples in one recent national survey (FIGURE 4.21).

Figure 4.21: FIGURE 4.21 The changing way Americans meet their partners A national survey of 2452 straight couples and 462 gay and lesbian couples reveals the increasing role of the Internet. (Data from Rosenfeld, 2013; Rosenfeld & Thomas, 2012.)

Might test-driving life together minimize divorce risk? In Europe, Canada, and the United States, those who live together before marriage (and especially before engagement) have had higher rates of divorce and marital dysfunction than those who did not (Goodwin et al., 2010; Jose et al., 2010; Manning & Cohen, 2012; Stanley et al., 2010). Two factors contribute. First, those who live together tend to be initially less committed to the ideal of enduring marriage. Second, they tend to become even less marriage-supporting while living together.

Although there is more variety in relationships today, the institution of marriage endures. Ninety-five percent of Americans have either married or want to (Newport & Wilke, 2013). In Western countries, people marry for love. What counts as a “very important” reason to marry? Among Americans, 31 percent say financial stability, and 93 percent say love (Cohn, 2013). And marriage is a predictor of happiness, sexual satisfaction, income, and physical and mental health (Scott et al., 2010). National Opinion Research Center surveys of more than 50,000 Americans since 1972 reveal that 40 percent of married adults, and only 23 percent of unmarried adults, have reported being “very happy.” Lesbian couples, too, report greater well-being than those who are single (Peplau & Fingerhut, 2007; Wayment & Peplau, 1995). Moreover, neighborhoods with high marriage rates typically have low rates of social pathologies such as crime, delinquency, and emotional disorders among children (Myers & Scanzoni, 2005).

What do you think? Does marriage correlate with happiness because marital support and intimacy breed happiness, because happy people more often marry and stay married, or both?

Relationships that last are not always devoid of conflict. Some couples fight but also shower each other with affection. Other couples never raise their voices yet also seldom praise each other or nuzzle. Both styles can last. After observing the interactions of 2000 couples, John Gottman (1994) reported one indicator of marital success: at least a five-to-one ratio of positive to negative interactions. Stable marriages provide five times more instances of smiling, touching, complimenting, and laughing than of sarcasm, criticism, and insults. So, if you want to predict which couples will stay together, don’t pay attention to how passionately they are in love. The pairs who make it are more often those who refrain from putting down their partners. To prevent a cancerous negativity, successful couples learn to fight fair (to state feelings without insulting) and to steer conflict away from chaos with comments like “I know it’s not your fault” or “I’ll just be quiet for a moment and listen.”

“Our love for children is so unlike any other human emotion. I fell in love with my babies so quickly and profoundly, almost completely independently of their particular qualities. And yet 20 years later I was (more or less) happy to see them go—I had to be happy to see them go. We are totally devoted to them when they are little and yet the most we can expect in return when they grow up is that they regard us with bemused and tolerant affection.”

Developmental psychologist Alison Gopnik, “The Supreme Infant,” 2010

Often, love bears children. For most people, this most enduring of life changes is a happy event—one that adds meaning, joy, and occasional stress (Nelson et al., 2013; Witters, 2014). “I feel an overwhelming love for my children unlike anything I feel for anyone else,” said 93 percent of American mothers in a national survey (Erickson & Aird, 2005). Many fathers feel the same. A few weeks after the birth of my first child I [DM] was suddenly struck by a realization: “So this is how my parents felt about me!”

When children begin to absorb time, money, and emotional energy, satisfaction with the marriage itself may decline (Doss et al., 2009). This is especially likely among employed women who, more than they expected, may carry the traditional burden of doing the chores at home. Putting effort into creating an equitable relationship can thus pay double dividends: greater satisfaction, which breeds better parent-child relations (Erel & Burman, 1995).

“To understand your parents’ love, bear your own children.”

Although love bears children, children eventually leave home. This departure is a significant and sometimes difficult event. For most people, however, an empty nest is a happy place (Adelmann et al., 1989; Gorchoff et al., 2008). Many parents experience a “postlaunch honeymoon,” especially if they maintain close relationships with their children (White & Edwards, 1990). As Daniel Gilbert (2006) has said, “The only known symptom of ‘empty nest syndrome’ is increased smiling.”

WORK For many adults, the answer to “Who are you?” depends a great deal on the answer to “What do you do?” For women and men, choosing a career path is difficult, especially during bad economic times. Even in the best of times, few students in their first two years of college or university can predict their later careers.

In the end, happiness is about having work that fits your interests and provides you with a sense of competence and accomplishment. It is having a close, supportive companion who cheers your accomplishments (Gable et al., 2006). And for some, it includes having children who love you and whom you love and feel proud of.

Well-Being Across the Life Span

166

4-19 How does our well-being change across the life span?

To live is to grow older. This moment marks the oldest you have ever been and the youngest you will henceforth be. That means we all can look back with satisfaction or regret, and forward with hope or dread. When asked what they would have done differently if they could relive their lives, people’s most common answer has been “taken my education more seriously and worked harder at it” (Kinnier & Metha, 1989; Roese & Summerville, 2005). Other regrets—“I should have told my father I loved him,” “I regret that I never went to Europe”—have also focused less on mistakes made than on the things one failed to do (Gilovich & Medvec, 1995).

“When you were born, you cried and the world rejoiced. Live your life in a manner so that when you die the world cries and you rejoice.”

Native American proverb

From the teens to midlife, people typically experience a strengthening sense of identity, confidence, and self-esteem (Huang, 2010; Robins & Trzesniewski, 2005). In later life, challenges arise: Income shrinks. Work is often taken away. The body deteriorates. Recall fades. Energy wanes. Family members and friends die or move away. The great enemy, death, looms ever closer. And for those in the terminal decline phase, life satisfaction does decline as death approaches (Gerstorf et al., 2008).

Prior to the very end, however, Gallup researchers have discovered that the over-65 years are not notably unhappy. Self-esteem remains stable (Wagner et al., 2013). Emotional experiences become more complex, allowing older people to experience various emotions that benefit their mental health (Demiralp et al., 2012; Schneider & Stone, 2015). Positive feelings, supported by enhanced emotional control, tend to grow after midlife, and negative feelings subside (Stone et al., 2010; Urry & Gross, 2010). Older adults increasingly use words that convey positive emotions (Pennebaker & Stone, 2003), and they attend less and less to negative information. Compared with younger Chinese and American adults, for example, older adults are more attentive to positive news (Isaacowitz, 2012; Wang et al., 2015).

No mystery.

Compared with teens and young adults, older adults tend to have a smaller social network, with fewer friendships (Wrzus et al., 2012). Like people of all ages, older adults are, however, happiest when not alone (FIGURE 4.22). Older adults experience fewer problems in their relationships—less attachment anxiety, stress, and anger (Chopik et al., 2013; Fingerman & Charles, 2010; Stone et al., 2010). With age, we become more stable and more accepting (Carstensen et al., 2011; Shallcross et al., 2013).

“At 20 we worry about what others think of us. At 40 we don’t care what others think of us. At 60 we discover they haven’t been thinking about us at all.”

The aging brain may help nurture these positive feelings. Brain scans of older adults show that the amygdala, a neural processing center for emotions, responds less actively to negative events (but not to positive events) (Mather et al., 2004). Brain-wave reactions to negative images also diminish with age (Kisley et al., 2007).

“The best thing about being 100 is no peer pressure.”

on turning 100

Moreover, at all ages, the bad feelings we associate with negative events fade faster than do the good feelings we associate with positive events (Walker et al., 2003). This leaves most older people with the comforting feeling that life, on balance, has been mostly good. Thanks to biological, psychological, and social-cultural influences, more and more people flourish into later life (FIGURE 4.23).

ANSWERS: Challenges: decline of muscular strength, reaction times, stamina, sensory keenness, cardiac output, and immune system functioning. Risk of cognitive decline increases. Rewards: positive feelings tend to grow; negative emotions are less intense; and anger, stress, worry, and social-relationship problems decrease.

Death and Dying

4-20 A loved one’s death triggers what range of reactions?

Warning: If you begin reading the next paragraph, you will die.

But of course, if you hadn’t read this, you would still die in due time. “Time is a great teacher,” noted the nineteenth-century composer Hector Berlioz, “but unfortunately it kills all its pupils.” Death is our inevitable end. We enter the world with a wail, and usually leave it in silence.

“Love—why, I’ll tell you what love is: It’s you at 75 and her at 71, each of you listening for the other’s step in the next room, each afraid that a sudden silence, a sudden cry, could mean a lifetime’s talk is over.”

Brian Moore,
The Luck of Ginger Coffey, 1960

Most of us will also suffer and cope with the deaths of relatives and friends. For most people, the most difficult separation they will experience is the death of a spouse—a loss suffered by four times more women than men. But for some people, grief is especially severe, because a loved one’s death comes suddenly and before its expected time on the social clock. The sudden illness or accident claiming a 45-year-old life partner or a child may trigger a year or more of memory-laden mourning that eventually subsides to a mild depression (Lehman et al., 1987).

For some, however, the loss is unbearable. One Danish long-term study of more than 1 million people found that about 17,000 of them had suffered the death of a child under 18. In the 5 years following that death, 3 percent of them had a first psychiatric hospitalization, a 67 percent higher rate than among other parents (Li et al., 2005).

Even so, reactions to a loved one’s death range more widely than most suppose. Some cultures encourage public weeping and wailing; others hide grief. Within any culture, individuals differ. Given similar losses, some people grieve hard and long, others less so (Ott et al., 2007). Contrary to popular misconceptions, however:

“Consider, friend, as you pass by, as you are now, so once was I. As I am now, you too shall be. Prepare, therefore, to follow me.”

Scottish tombstone epitaph

Facing death with dignity and openness helps people complete the life cycle with a sense of life’s meaningfulness and unity—the sense that their existence has been good and that life and death are parts of an ongoing cycle. Although death may be unwelcome, life itself can be affirmed even at death. This is especially so for people who review their lives not with despair but with what Erik Erikson called a sense of integrity—a feeling that one’s life has been meaningful and worthwhile.

ANSWER: Muscular strength, reaction time, sensory abilities, and cardiac output begin to decline in the late twenties and continue to decline throughout middle adulthood (roughly age 40 to 65) and late adulthood (the years after 65). Women's period of fertility ends with menopause around age 50; men have no similar age-related sharp drop in hormone levels or fertility. In late adulthood, the immune system weakens, increasing susceptibility to life-threatening illnesses. Chromosome tips (telomeres) wear down, reducing the chances of normal genetic replication. But for some, longevity-supporting genes, low stress, and good health habits enable better health in later life.

ANSWER: As the years pass, recall begins to decline, especially for meaningless information, but recognition memory remains strong. Developmental researchers study age-related changes such as in memory with cross-sectional studies (comparing people of different ages) and longitudinal studies (retesting the same people over a period of years). “Terminal decline” describes the cognitive decline in the final few years of life.

ANSWER: Adults do not progress through an orderly sequence of age-related social stages. Chance events can determine life choices. The social clock is a culture's preferred timing for social events, such as marriage, parenthood, and retirement. Adulthood's dominant themes are love and work, which Erikson called intimacy and generativity.

ANSWER: Self-confidence tends to strengthen across the life span. Surveys show that life satisfaction is unrelated to age. Positive emotions increase after midlife and negative ones decrease.

ANSWER: People do not grieve in predictable stages, as was once supposed. Strong expressions of emotion do not purge grief, and bereavement therapy is not significantly more effective than grieving without such aid. Erikson viewed the late-adulthood psychosocial task as developing a sense of integrity (versus despair).
