  1. Chapter 13: Early Adulthood: Physical and Cognitive Development Development Across the Lifespan

  2. Physical Development and Stress In Early Adulthood • In most respects physical development and maturation are complete by early adulthood. • Full height, proportional limbs, tend to be healthy, vigorous, energetic • Most people are at the peak of their physical capabilities. • The brain continues to grow in both size and weight, reaching its maximum in early adulthood. • Brain wave patterns show changes (more mature patterns)

  3. The senses are as sharp as they will ever be. • No significant deterioration in vision (until the 40’s) • Hearing is at its peak • Taste, smell, sensitivity to touch good • Most professional athletes are at their peak during early adulthood • Psychomotor abilities (eye-hand coordination, etc.)

  4. Physical Fitness in Early Adulthood  The superior physical capabilities common to early adulthood don’t come naturally; exercise and diet are required to reach full physical potential • Although exercise is talked about a lot in the U.S., no more than 10 % of Americans exercise enough to keep themselves in good physical shape. • Less than ¼ participate in moderate exercise on a regular basis

  5. Unfortunately…. • Exercise is largely an upper- and middle-class phenomenon • People of low socioeconomic status (SES) often lack the time or money to participate • People in general do not exercise enough! • The conspicuousness of exercise in the U.S. is misleading! • Less than 10% of Americans exercise sufficiently to keep them in shape • Less than a quarter engage in even moderate regular exercise

  6. Physical Fitness in Early Adulthood, continued • According the CDC (center for disease control), people should get 30 minutes of moderate physical activity at least 5 days per week • Can be continuous, or in 10 minute chunks (as long as it totals 30 min. per day) • Examples of moderate activity: walking briskly, biking/10 mph, golfing (no cart!), fishing, ping pong, household chores (weeding, vacuuming, etc.)

  7. The Result of Fitness: Longevity The greater the fitness level, the lower the death rate.

  8. increases cardiovascular fitness lung capacity increases muscles become stronger body becomes more flexible and maneuverable reduces osteoporosis, the thinning of bones, in later life optimizes the immune response decreases stress, anxiety, and depression increases sense of control and feelings of accomplishment increases longevity Other advantages to regular exercise

  9. Health & exercise in early adulthood, continued • A lack of exercise may lead to poor health in general, but health risks in general are low during early adulthood • Young adults are less susceptible to colds and illnesses • Good immune systems • Tendency to exercise • More likely to die in accidents (usually car related) than most other causes

  10. Health & exercise in early adulthood, continued  The leading causes of death among young adults (ages 25-34) are: • accidents • AIDS • cancer • heart disease • Suicide ~ At age 35, this reverses and illness and disease become more likely causes (for the 1st time since infancy)

  11. Not all people fare equally well in early adulthood… • Men are more apt to die from accidents than women • African-Americans have twice the death rate of Caucasians. ~~~The murder rate in the U.S. is significantly higher than in any other developed country. —U.S rate = 21.9 per 100,000 me; Japanese rate = 0.5 murders per 100,000 men <4000% difference!>

  12. Tracking Murder

  13. Racial Factors effect murder rates Murder is the fifth most frequent cause of death for young White Americans (1 in 131 chance in lifetime) Murder is themost frequent cause of death for African-Americans (1 in 21 chance in lifetime) ---In some areas of the country, a young black male has a higher probability of being murdered than a soldier in the Vietnam War had of being killed! • African American male: 1 in 21 chance of being murdered in his lifetime • European American male: 1 in 131 chance

  14. Eating, Nutrition, and Obesity • Most young adults know which foods are healthy, but ignore good nutrition • Since physical growth is beginning to decline in this developmental period, young adults must reduce the calories they were used to during adolescence

  15. Eating, Nutrition, and Obesity, continued • Young adults will put on weight if they do not eat sensibly. • 31 % of the adult population is classified as overweight. • 7 % of men and 10 % of women between the ages of 20 and 25 are obese. • The rate of obesity in the U.S. is increasing

  16. Obesity on the Rise…

  17. Genetic factors may lead people to become obese. • Environmental and social factors also produce obesity. • Obese people may have a higher WEIGHT SET POINT, the particular level the body strives to maintain. • Most people who diet eventually gain back the weight

  18. Physical Disabilities in Young Adulthood: Coping With Physical Challenge • Some 50+ million Americans are physically challenged - or disabled - a condition that substantially limits a major life activity such as walking or vision. • Fewer than 10 % of people with major handicaps have finished high school. • Fewer than 25 % of disabled men and 15 % of disabled women work full time. • Adults with handicaps are often unemployed, or stuck in routine, low-paying jobs. ~~WHY? BARRIERS!

  19. Discrimination and prejudice are barriers and affect the way that people with disabilities view themselves (their cognitive development!) • Despite the Americans with Disabilities Act (1990), many older buildings are inaccessible to wheelchairs. • Prejudice and discrimination affect the way disabled people think of themselves. • Pity, avoidance • Treating adults as children • Seeing disabled person as a category rather than an individual

  20. Stress & Coping in Early Adulthood: Another Factor Effecting Cognitive Development • STRESS is the response to events that threaten or challenge an individual. • Our lives are filled with events and circumstances known as stressors, that cause threats to our well-being.

  21. (Stress & Coping in Early Adulthood, continued) • Stressors can be both pleasant events and unpleasant events (weddings, winning awards, exams, arguments) • Long-term, continuous exposure to stressors may result in a reduction of the body's ability to deal with stress. • People become more susceptible to diseases as their ability to fight off germs declines

  22. According to Lazarus and Folkman, not every situation produces stress • Lazarus and Folkman believe that people move through a series of stages that determine whether or not they will experience stress (the way a situation is appraised will determine the perception of stress) • PRIMARY APPRAISAL is the assessment of an event to determine whether its implications are positive, negative, or neutral • SECONDARY APPRAISAL is the assessment of whether one's coping abilities and resources are adequate to overcome the harm, threat, or challenge posed by the potential stressor

  23. ~The way an individual evaluates a potential stressor determines whether the individual will experience stress. Steps in the Perception of Stress

  24. Overall Principals Predicting When an Event will be Stressful (Shelly Taylor, 1991) • Events and circumstances that produce negative emotions are more likely to produce stress. • Situations that are uncontrollable or unpredictable are more likely to produce stress. • Events and circumstances that are ambiguous and confusing produce more stress. • People who must accomplish simultaneously many tasks are more likely to experience stress. • Stress Quiz in text

  25. The Consequences of Stress During Early Adulthood • Stress may lead to PSYCHOSOMATIC DISORDERS,medical problems caused by the interaction of psychological, emotional, and physical difficulties. • Some young adults are better than others at COPING,the effort to reduce, or tolerate the threats that lead to stress.

  26. Styles of Coping… • Problem-focused coping is the attempt to manage a stressful problem or situation by directly changing the situation to make it less stressful. • Emotion-focused coping involves the conscious regulation of emotion. • Coping is also aided by the presence of social support, assistance and comfort supplied by others. • Defense coping involves unconscious strategies that distort or deny the true nature of the situation.

  27. Cognitive Development in Early Adulthood • Physical development slows down during early adulthood, but does cognitive? • Piaget and others argued that by the time the teen years were finished, thinking stabilized • BUT increasing evidence suggests that this part of Piaget’s theory was incorrect!

  28. Cognitive Development in Early Adulthood, continued… • Developmentalist Giesela Labouvie-Vief suggests that the nature of thinking changes qualitatively during early adulthood. • Adults exhibit POSTFORMAL THOUGHT, thinking that goes beyond Piaget's formal operations. • Adult predicaments are sometimes solved by relativistic thinking rather than pure logic. • Postformal thought acknowledges that the world sometimes lacks purely right and wrong solutions and adults must draw upon prior experiences to solve problems.

  29. K. Warner Schaie suggests that adults' thinking follows a set pattern of stages • The ACQUISITIVE STAGE,which encompasses all of childhood and adolescence, in which the main developmental task is to acquire information. • The ACHIEVING STAGEis the point reached by young adults in which intelligence is applied to specific situations involving the attainment of long-term goals regarding careers, family, and societal contributions.

  30. Schaie stages of cognitive development, continued… • The RESPONSIBLE STAGE is the stage where the major concerns of middle-aged adults relate to their personal situations, including protecting and nourishing their spouses, families, and careers. • The EXECUTIVE STAGE is the period in middle adulthood when people take a broader perspective than earlier, including concerns about the world. • The REINTEGRATIVE STAGE is the period of late adulthood during which the focus is on tasks that have personal meaning

  31. Schaie’s Stages of Adult Development

  32. “How do you meet your goals?”-- The way adults answer has a lot to do with their future success according to psychologist Robert Sternberg. • Robert Sternberg, in his TRIARCHIC THEORY OF INTELLIGENCEsuggests that intelligence is made up of three major components: • Componential aspects • Experiential components • Contextual factors

  33. Sternberg’s Triarchic Theory of Intelligence

  34. Sternberg’s Triarchic Theory of Intelligence • Componential intelligence relates to the mental components involved in analyzing data, and in solving problems, especially problems involving rational behavior. (traditional IQ tests focus on this aspect) • Experiential intelligence refers to the relationship between intelligence, people's prior experience, and their ability to cope with new situations

  35. (Sternberg, continued) • Contextual intelligence involves the degree of success people demonstrate in facing the demands of their everyday, real-world environments. ~~ Sternberg contends that success in a career necessitates this type of intelligence (contextual), also called PRACTICAL INTELLIGENCE,intelligence that is learned primarily by observing others and modeling their behavior.

  36. Sample items from a test that taps four domains of practical intelligence (see text)

  37. Expanding on Sternberg’s theory… Psychologist Seymour Epstein argues that constructive thinking, a form of practical intelligence, underlies success in such areas as social relationships and physical and emotional health

  38. Creativity: Novel Thought in Early Adulthood • The major works of many creative individuals were produced during early adulthood • Psychologist Sarnoff Mednick proposed that higher productivity exists during early adulthood • One factor: “familiarity breeds rigidity” (the more people know about something, the more rigid they become) • Clearly not universal

  39. Creativity & Age…The period of maximum creativity differs depending on the particular field.

  40. (Creativity: Novel Thought in Early Adulthood, continued) • CREATIVITY, combining responses or ideas in creative ways, is at its peak for many individuals during early adulthood. • People in early adulthood may be at the peak of their creativity because many of the problems they encounter on a professional level are novel. • Creative people are willing to take risks. • Creative people develop and endorse ideas that are unfashionable or regarded as "wrong". • Not all people reach their creative peak in early adulthood

  41. Life events & cognitive development • Some research suggests that major life events, such as marriage, birth of a child, starting a first job, having a child, buying a house, may lead to cognitive growth. • The ups and downs of life events may lead young adults to think about the world in novel, more complex, sophisticated, and often less rigid ways. • Applying postformal thought (Labouvie-Vief) allows them to deal more effectively with the complex social world

  42. College: Pursuing Higher Education  Nationwide, a minority of high school graduates enter college. • 40 % of White Americans enter college. • 29 % of African-Americans enter college. • 31 % of Hispanic high school graduates enter college.  Only about 40 % of those who start will graduate from college in 4 years. • ½ will eventually finish. • 70 % of African-Americans drop out of college.

  43. By the year 2000, the U.S. Dept. of Education projects increases in college attendance • Minority students are an increasingly larger proportion of the college population. • African-American students have increased by 13 %. • Hispanic students have increased by 22 %. • White students have increased by 6 %

  44. College Enrollment by Racial Group Ethnic diversity has increased over the last several decades.

  45. Changes in College Attendance, continued… ~These changes reflect differences in the racial & ethnic composition of the U.S. & the growing realization that higher education improves economic well-being.

  46. Education & Economic Security

  47. Higher education, continued • There are now more women than men enrolled in college, and by the year 2007, women's enrollment is expected to increase 30 % from 1995 compared to an increase of only 13 % for men. • College is a period of developmental growth that encompasses mastery not just of particular bodies of knowledge, but of ways of understanding the world.

  48. The Changing College Student: Never too Late to go to College • 40 % of college students today are 25 years of age or older. • The average age of a community college student is 31. • A college degree is becoming increasingly important in obtaining a job. • Many employers require and encourage their workers to update their skills.
