Adulthood, Aging, Death, and Dying

The board devotes heavy weight to adulthood and the end of life because a licensed psychometrician's caseload is not limited to children: geriatric screening, caregiver burnout, and grief counseling are everyday referrals in Philippine clinics, hospices, and senior citizen centers. Examiners routinely test whether you can tell normal forgetfulness from dementia, or a textbook "stage of grief" from what current research actually supports. This lesson sorts adult development into its tested pieces: the eras themselves, Levinson's seasons, generativity, the two faces of intelligence, pathological aging, competing theories of successful aging, and the models of dying and grief that follow one another in the literature.

Mapping early, middle, and late adulthood

Developmentalists typically divide adulthood into three broad periods. Early adulthood (roughly 20 to 40) is marked by peak physical functioning, career establishment, and, per Erikson, the crisis of intimacy versus isolation, forming a committed identity-sharing bond without losing one's own identity. Middle adulthood (roughly 40 to 65) brings the first reliable physical declines alongside peak earning power, caregiving for both children and aging parents (the so-called "sandwich generation"), and Erikson's generativity versus stagnation crisis. Late adulthood (65 onward) is defined less by chronological age than by role transitions such as retirement and widowhood, and culminates in Erikson's final crisis, integrity versus despair, an honest look back that either affirms a life well lived or curdles into regret. These era boundaries are approximate and overlap by design, since no one crosses from one season of life to the next on a birthday.

Levinson's seasons of life and the midlife transition

Daniel Levinson, in The Seasons of a Man's Life (1978, later extended to women), proposed that adulthood unfolds through alternating stable periods and transitions, each built around a life structure, the underlying pattern of relationships, work, and roles a person organizes life around at a given time. Stable periods last about six to eight years and involve building a life structure; transitions last about four to five years and involve questioning and revising it. The best-known transition is the midlife transition (roughly ages 40 to 45), in which Levinson argued adults confront four Jungian polarities: young versus old, destruction versus creation, masculine versus feminine, and attachment versus separateness, reassessing the life structure built in early adulthood against a dawning awareness of mortality.

The popular term midlife crisis did not originate with Levinson; it was coined by psychoanalyst Elliott Jaques in 1965. This is a favorite board trap: Levinson himself described the midlife transition as a normative, developmentally necessary reappraisal, not necessarily a crisis, and large longitudinal studies such as the MIDUS (Midlife in the United States) project found that most adults navigate midlife without dramatic upheaval. Expect the exam to reward the answer that a "crisis" is the exception, not the rule, even within Levinson's own framework.

Generativity versus stagnation in middle adulthood

Erikson's seventh psychosocial crisis, generativity versus stagnation, is the single most-tested concept for middle adulthood. Generativity is the adult's concern for establishing and guiding the next generation, expressed through parenting, mentoring, teaching, creative work, or civic contribution; failure to find this outward focus produces stagnation, a self-absorbed sense of personal impoverishment. Erikson tied generativity to the virtue of care. Researcher Dan McAdams later extended the construct with the generativity script, showing that highly generative adults tend to narrate their lives as a redemption sequence, turning early hardship into a later commitment to benefit others, a useful elaboration if a vignette asks about mentoring or legacy-building in a 45-year-old client.

Physical and cognitive aging: crystallized versus fluid intelligence

Physically, middle and late adulthood bring predictable, universal changes: presbyopia (loss of near-focus in the eye), presbycusis (high-frequency hearing loss), slower reaction time, reduced muscle mass (sarcopenia), and, for women, menopause, the cessation of menstruation typically in the late 40s to early 50s. None of these, by themselves, signal disease.

Cognitively, the board leans hard on Raymond Cattell and John Horn's distinction between two components of intelligence. Crystallized intelligence is accumulated knowledge, vocabulary, and learned skill, built from a lifetime of experience and education; it holds steady or even rises into late adulthood. Fluid intelligence is the capacity for novel problem-solving, abstract reasoning, and processing speed, independent of prior knowledge; it peaks in early adulthood and declines gradually thereafter, largely tracking the slowing of processing speed described by Timothy Salthouse's processing-speed theory of cognitive aging.

Feature	Crystallized intelligence	Fluid intelligence
What it measures	Accumulated knowledge, vocabulary, learned facts	Novel reasoning, abstraction, processing speed
Trajectory with age	Stable or increases into late adulthood	Peaks in early adulthood, declines gradually
Depends on	Culture, education, experience	Neural processing efficiency
Example test	Vocabulary or general-information subtests	Matrix reasoning, novel puzzle-solving

Normal aging versus dementia and Alzheimer's disease

Normal aging brings mild, non-progressive slips: occasional word-finding trouble, needing more time to learn new material, misplacing objects but retracing steps to find them, all without impairing independent daily functioning. Mild cognitive impairment (MCI) is a measurable step beyond this baseline, a noticeable memory or thinking decline greater than expected for age that does not yet disrupt independent living, and is treated as a risk marker (not a guarantee) for later dementia. Dementia is a progressive, functionally impairing decline across multiple cognitive domains. Alzheimer's disease is its most common cause, marked pathologically by beta-amyloid plaques and neurofibrillary tangles (misfolded tau protein) that first devastate the hippocampus, producing the hallmark early symptom of poor new-memory formation before language and executive function erode. Vascular dementia (from strokes or reduced blood flow) and Lewy body dementia (with early hallucinations and motor symptoms) are the next most-tested subtypes, distinguished from Alzheimer's mainly by their onset pattern and non-memory symptoms appearing earlier.

In the Philippines, RA 10868, the Philippine Alzheimer's Disease Law (2016), mandates government programs for public awareness, early detection, and support services for persons with Alzheimer's and their caregivers, while formal neuropsychological screening for dementia remains practice reserved for licensed psychologists and psychometricians under RA 10029, the Philippine Psychology Act of 2009.

Theories of aging: activity, disengagement, and socioemotional selectivity

Three competing accounts explain what "successful aging" looks like socially.

Theory	Core claim	Key proponent(s)
Disengagement theory	Mutual, gradual withdrawal of the aging individual and society is natural and adaptive for both	Elaine Cumming and William Henry (1961)
Activity theory	Successful aging means maintaining middle-age levels of activity, replacing lost roles with new ones	Robert Havighurst
Continuity theory	Adults maintain stable personality and preferred coping strategies, adapting late-life roles to fit lifelong patterns	Robert Atchley
Socioemotional selectivity theory (SST)	As perceived remaining time shrinks, people shift goals from knowledge-seeking to emotionally meaningful relationships	Laura Carstensen

Disengagement theory was the first formal aging theory and remains the most-criticized: research consistently shows most older adults who stay active and connected report greater life satisfaction, which is why activity theory displaced it as the dominant early view. SST is the most contemporary and most board-favored explanation: it does not claim older adults withdraw because of decline, but because a shrinking time horizon makes them selectively prune peripheral relationships to invest in the emotionally closest ones, producing the well-documented positivity effect, older adults' tendency to attend to and remember positive information over negative information more than younger adults do.

Kubler-Ross and models of grief

Elisabeth Kubler-Ross, in On Death and Dying (1969), interviewed terminally ill patients and proposed five stages of coming to terms with one's own dying, easily remembered by the acronym DABDA.

Stage	Core experience
Denial	"This isn't happening to me"; a buffer against overwhelming news
Anger	"Why me?"; resentment directed outward at others or fate
Bargaining	Attempting to postpone death through promises, often to a higher power
Depression	Grieving present and coming losses; withdrawal and sadness
Acceptance	A calm, if not happy, coming to terms with the reality of dying

The board-tested caution is that Kubler-Ross herself never claimed the stages are linear, universal, or that every dying person passes through all five; later research found wide individual variation in order, number, and even presence of these reactions, and the model has been criticized for lacking strong empirical support despite its enduring popularity.

Grief research moved beyond Kubler-Ross in several directions. John Bowlby and Colin Murray Parkes described bereavement as phases of shock and numbness, yearning and searching, disorganization and despair, and reorganization. William Worden's task-based model reframes grieving as active work across four tasks: accepting the reality of the loss, processing the pain of grief, adjusting to an environment without the deceased, and finding an enduring connection while moving forward with life. Stroebe and Schut's dual process model describes healthy grieving as an oscillation between loss-oriented coping (confronting the pain and the loss directly) and restoration-oriented coping (attending to life changes, new roles, and distraction), rather than steady linear progress toward closure. Finally, the continuing bonds model (Klass, Silverman, and Nickman) overturned the older Freudian assumption that healthy mourning requires severing emotional ties to the deceased (grief work or decathexis); it instead frames maintaining an ongoing inner connection with the deceased as normal and often healthy.

Board traps and takeaways

• Levinson's midlife transition is a normative developmental reassessment, not automatically a "crisis"; the term "midlife crisis" traces to Elliott Jaques, not Levinson, and most adults navigate the transition without turmoil.
• Generativity versus stagnation is Erikson's middle-adulthood crisis; do not confuse it with integrity versus despair, which belongs to late adulthood.
• Crystallized intelligence rises or holds steady with age; fluid intelligence declines from early adulthood onward. A vocabulary test result cannot substitute for a novel-reasoning result on the exam.
• Normal aging and dementia differ on function, not just memory lapses: normal aging does not impair independent daily living, while dementia is progressive and functionally disabling. MCI sits between the two as an at-risk, not yet impairing, state.
• Disengagement theory is the historically superseded view; activity theory and, more recently, socioemotional selectivity theory better fit the evidence that engaged, selectively-invested older adults report higher well-being.
• Kubler-Ross's five stages are not sequential or universal; treat DABDA as a description of possible reactions, and remember that dual process, task-based, and continuing bonds models represent the field's move away from a strict, linear "stages of grief" picture.
