A transitional period between childhood and adulthood
In our society, begins at around 13 and ends about 22
It is not universal across cultures
Physical changes
Pubescence: the two-year span preceding puberty
during which the changes leading to physical and sexual maturity take
place
Children grow taller and heavier
Develop secondary sex characteristics:
physical features that distinguish one gender from the other but that
are not essential for reproduction
Boys: voice changes, develop facial hair, etc.
Girls: experience breast growth, widening of pelvis,
etc.
Capacity to reproduce is not attained in
pubescence
Puberty: the stage that marks the beginning of
adolescence and during which sexual functions reach maturity
Primary sex characteristics (the structures
necessary for reproduction) develop fully
Females experience menarche: the first
occurrence of menstruation
Males develop capacity to ejaculate sperm
Puberty arrives about two years later in boys than in
girls
A change in the timing of puberty has been observed over
recent generations
Today's adolescents begin puberty earlier, complete it
more rapidly
Apparently reflects improvements in nutrition, medical
care
Heart, lungs increase in size; heart rate drops
More pronounced in boys than girls
Responsible, in part, for boys' superior performance
in certain physical activities
Variation in onset of pubescence and puberty is normal
Timing can affect psychological adjustment
Girls who mature early and boys who mature late tend
to have most problems
Cognitive changes
Adolescents can think abstractly (not just concretely) and
more efficiently
Become more self-aware, self-reflective
Can apply logical skills to concepts such as love,
justice, truth
Egocentrism: the tendency to view reality in
line with one's own idiosyncratic perception
Adolescents wrongly assume they are the center of
attention (i.e., the imaginary audience effect)
Another form of egocentrism is personal fable
Adolescents tend to believe they are unique; others
can't understand their special experiences
High-risk behavior may be attributable to personal
fable
Egocentrism seems to disappear as adolescents mature
Personality changes
The search for identity
According to Erik Erikson, the main challenge of
adolescence is developing a clear sense of identity
Marcia's four possible outcomes of psychosocial crisis:
foreclosure, moratorium, identity diffusion, identity achievement
Sense of identity evolves gradually
As result of innumerable daily decisions (e.g.,
whether or not to date a particular person, to become sexually active,
etc.)
Adolescents gradually achieve psychological distance
from parents
Time of turmoil?
Overall, evidence indicates that majority of teenagers
do not experience inordinate amount of turmoil
Differences between those who can cope and those who
can't become increasingly obvious
Those who have difficulty coping may develop
depression, suicidal behavior, drug problems
Incidence of problems is relatively low
In recent years, there has been an increase in some
psychological, social problems
Adolescent suicide
Recent years have seen surge in adolescent suicide
But only small minority of adolescents commit suicide
White males more likely to commit suicide than black
males
Ratio of attempted to completed suicides is higher for
adolescents than for any other age group
Suicide attempts may be a "cry for help"
Factors in adolescent suicide attempts
Long history of stress, personal problems
Conflicts with parents, girlfriends, boyfriends
The expanse of adulthood
Social clock: a person's notion of a developmental
schedule that specifies what he or she should have accomplished by certain
points in life
Can exert considerable influence over important decisions
Important life events that occur too early or too late can
produce stress
Erikson's view of adulthood
Stage six: intimacy versus isolation
Corresponds to young adulthood
Focuses on learning to open up to others, to commit to
others
Jacob Orlofsky's five intimacy statuses: intimate,
preintimate, stereotyped, pseudointimate, isolated
Some research support for Erikson's notion that identity
precedes intimacy
Early adulthood (from about age 20 to 40)
Adjusting to the world of work
Individuals need to complete schooling, secure first job
Many people still only tentatively committed to chosen
occupation
Adjusting to marriage and family life
First few years of married life tend to be very happy
Arrival of first child represents major transition
After arrival of children, marital satisfaction tends to
decline (until middle adulthood)
Middle adulthood (from about age 40 to 65)
Stage seven: generativity versus stagnation
Challenge is to acquire concern for future generations
Can meet challenge by providing guidance to younger
people
Confronting the aging process
A number of physical transformations occur
People forced to acknowledge mortality
Transitions in the parenting role
Parental influence over children declines
Parents rate adolescent stage (of children) as most
difficult
Although "emptying of nest" is widely believed to be
traumatic, few seem to experience it as such
Transitions in the work role
Those in stable career pattern are at peak of
careers
Those in changing careers pattern a more varied
group
Is there a midlife crisis?
Two studies conducted in 1970s concluded that midlife
crisis is a normal transition
More recent studies have found evidence of midlife
crisis in only small minority
Late adulthood (after age 65)
Stage eight: integrity versus despair
Challenge is to achieve (ego) integrity
Researchers have demonstrated support for several of
Erikson's propositions
Erikson's theory is useful, relatively accurate
Retirement
Today individuals tend to retire earlier than 65
Individuals approach retirement with highly variable
attitudes
Changes in support networks
Couples' relationship satisfaction tends to increase
later in life
Siblings may become more important than they were
earlier
Friends seem to play more significant role in life
satisfaction
For African Americans, fictive kin become an
important component of social support networks
Aging: a gradual process
Physical changes
Changes in appearance
Height tends to decrease slightly
Weight tends to increase
Hair thins out, becomes gray
Older people tend to view themselves as less attractive
Particularly problematic for women
May be a "double standard" of aging
Changes in vision and hearing
Most people become increasingly far-sighted until
mid-60s, then trend is toward greater nearsightedness
Changes in vision may be responsible for accidents
Typically, noticeable hearing losses do not show up
until people reach their 50s
Vision, hearing loss often make interpersonal
interaction more difficult
Small sensory losses in touch, taste, and smell have
been detected, usually after age 50
Neurological changes
Neurons: individual cells that receive,
integrate, and transmit information
Dementia: an abnormal condition marked by
multiple cognitive deficits including memory impairment
Can be caused by variety of disorders, including
Alzheimer's disease, Parkinson's disease, AIDS
Dementia, "senility" not part of normal aging process
Alzheimer's disease can strike during middle age or
later
Precise causes still unknown, but associated with
changes in brain chemistry and structure
Characterized by progressive deterioration, ending in
death
Beginnings are subtle, difficult to detect
Eventually, profound memory loss develops
Hormonal changes
Do not appear to be cause of declining sexual
activity
Such changes are more likely related to social norms
and negative stereotypes
Older women may have lack of opportunity for sex
Menopause: the time when menstruation
ceases
Reactions vary greatly
Episodes of moderate physical discomfort during
transitional phase are fairly common
Changes in health status
Quality of health tends to diminish
Lifestyle differences, access to health care play
important role in maintaining health
Relatively few elderly Americans live in nursing homes,
although numbers increase with age
Things to do to increase likelihood of good health
Exercise regularly
Eat healthy diet
Cognitive changes
Intelligence
IQ fairly stable throughout adult years
Small decline often begins after age 60
IQ drops precipitously in few years before death
Memory
Some evidence for moderate loss in long-term memory,
although most studies have been based on artificial laboratory tasks
Age-related memory losses moderate, not universal
Cultural attitudes may affect memory in elderly
No evidence to support notion that older people have
vivid recollections of events in distant past while being forgetful
about recent events
Learning and problem solving
Ability to focus attention, handle multiple inputs seems
to decline
Speed of processing most likely to be affected
Problem-solving ability generally unimpaired when
people are given enough time
Quantity rather than quality of intellectual activity
seems most affected
Personality changes
Research findings appear contradictory
Some traits tend to remain stable (e.g., emotional
stability, extraversion)
Other traits more likely to change (e.g., masculinity,
femininity)
Death and dying
Attitudes about death
Death system: the collection of rituals and
procedures used by a culture to handle death
Vary from culture to culture
Most common strategy in our culture is avoidance
Avoidance, negativism not universal features of all
death systems
Well-formulated personal philosophy of death may reduce
anxiety
The process of dying
Pioneering researcher Elisabeth Kubler-Ross proposed five
stages of dying
Denial
Anger
Bargaining
Depression
Acceptance
Views of Kubler-Ross have been heavily criticized
Researchers have not always found support for five
stages
Dying people seem to show variety of conflicting or
alternating reactions
Bereavement and grieving
Bereavement: the painful loss of a loved one
through death
Mourning: formal practices of an individual and
a community in response to a death
Cultural variations
In America, bereaved are encouraged to break emotional
ties with deceased relatively quickly and return to regular routines
In Japan, bereaved are encouraged to maintain emotional
ties to deceased
The grieving process
John Bowlby suggests four stages in grieving process
Numbness
Yearning
Disorganization and despair
Reorganization
Research findings suggest grief does not follow
straightforward path
Camille Wortmann, Roxane Silver found four distinct
patterns of grieving: normal, chronic, delayed, and absent
Reactions seem to differ as a function of person's
relationship to deceased (e.g., spouse, parent)
Coping with bereavement
People need sympathy, support of family, friends
Particularly difficult situation occurs when child loses
a parent to death
Application: becoming an effective parent
Maternal behavior and infant-mother attachment
Infants' attachment to mother is not automatic
Mary Ainsworth and colleagues concluded that infants can
be grouped into three attachment styles
Avoidant: babies tend to ignore mothers
Anxious-ambivalent: babies seem to desire
contact, but actively resist mother
Securely attached: babies welcome contact with
mother
Recent research suggests fourth attachment
style--disorganized/disoriented (babies drawn to caregivers, yet
fear them because of past, negative experiences)
Day care and attachment
A hotly debated topic
Jay Belsky's research suggests non-maternal care for more
than 20 hours per week can negatively affect maternal attachment
Other research indicates that day care can have beneficial
effects on children's intellectual, social development
Effects of day care generally depend on quality of care
provided
Dimensions of child-rearing
Two major dimensions underlie parenting behavior
Parental acceptance
Parental control
Diana Baumrind's "parenting styles"
Authoritative parents
Characterized by high acceptance, high control
Parents maintain firm control, but take into account
child's unique, changing needs
Authoritarian parents
Characterized by low acceptance, high control
Parents highly demanding, use physical punishment
Permissive parents
Characterized by high acceptance, low control
Parents allow children free expression of impulses,
set few limits
Neglectful parents
Characterized by low acceptance, low control
Parents not particularly involved with or supportive
of their children
Effects of parenting styles
Children of authoritative parents tend to do well in
school; are self-reliant, cooperative, friendly
Children of authoritarian parents tend to do less well in
school; have lower self-esteem, poorer social skills
Children of permissive parents tend to have lower grades;
are undisciplined, impulsive, easily frustrated
Children of neglectful parents tend to have low
self-esteem; are moody, impulsive, aggressive
Correlational nature of data limit ability to establish
causal link
Rearing adolescents
Increasing autonomy of adolescents requires more equal
parent-child relationship
Negotiating shifts in power can be difficult
Authoritative parents who are willing to respond to
their children's input are most likely to avoid turmoil
Authoritarian parents may promote hostility, rebellion
in their adolescent children
Permissive and neglectful parents may be faced with
adolescents whose behavior is completely out of hand
Toward effective parenting (i.e., "basic rules")
Set high, but reasonable standards
Stay alert for "good" behavior and reward it
Explain your reasons when you ask your child to do
something
Encourage children to take perspective of others
Enforce rules consistently
Using punishment effectively
Punishment often has unintended, negative side effects
May trigger strong, negative, emotional responses
Heavy punishment can result in general suppression of
behavioral activity
Harsh physical punishment can lead to increase in
aggressive behavior
Guidelines for using punishment effectively
Punishment should not damage child's self-esteem
Punishment should be swift
Punishment should be consistent
Punishment should be explained
Parent should point out alternative, positive ways for
child to behave and reinforce those actions
