2 years

What is the biggest influence on childhood obesity?

A combination of genes and the environment

Which capability achieves adult-like levels during adolescence?

Both cognitive-processing capacity and processing speed

How do adolescents reason about moral issues?

Kohlberg proposed that moral reasoning includes preconventional, conventional, and postconventional levels. Moral reasoning is first based on rewards and punishments and much later on personal moral codes.

Will an adolescent apply the same level of reasoning when judging information that supports her beliefs and information that contradicts them?

No, adolescents selectively apply stronger standards to contradictory information so that it does not threaten their beliefs

What physical changes during adolescence mark the transition to a mature young adult?

Puberty includes bodily changes in height and weight as well as sexual maturation. Girls typically begin the growth spurt earlier than boys, who acquire more muscle, less fat, and greater heart and lung capacity. The brain communicates more effectively, and the frontal cortex continues to mature. Sexual maturation, which includes primary and secondary sex characteristics, occurs in predictable sequences for boys and girls.

What are common obstacles to healthy growth in adolescence?

• Accidents involving automobiles or firearms are the most common cause of death in American teenagers. Many of these deaths could be prevented if, for example, adolescents did not drive recklessly (e.g., too fast and without wearing seat belts). Adolescents often see themselves as invulnerable to risk and often place greater value on the rewards associated with risky behavior.

What changes in problem-solving and reasoning take place in adolescence?

• Adolescents often solve problems analytically, using mathematics or logic. They also acquire skill in detecting weaknesses in scientific evidence and in logical arguments. But they don't consistently use these skills, sometimes resorting to simpler heuristics and sometimes allowing beliefs interfere with reasoning.

What other factors influence moral reasoning?

• As predicted by Kohlberg's theory, people progress through the stages in sequence and morally advanced reasoning is associated with more frequent moral behavior. However, Kohlberg's theory ignores the impact of caring, which often influences moral reasoning. And adolescents often balance fairness with group loyalty.

How do increases in content knowledge, strategies, and metacognitive skill influence adolescent cognition?

• Content knowledge increases to expertlike levels in some domains, and strategies and metacognitive skills become more sophisticated.

What are the elements of a healthy diet for adolescents? Why do some adolescents suffer from eating disorders?

• For proper growth, teenagers need to consume adequate calories, calcium, and iron. Unfortunately, many teenagers do not eat properly and do not receive adequate nutrition. - Anorexia and bulimia, eating disorders that typically affect adolescent girls, are characterized by an irrational fear of being overweight. Adolescents are at greatest risk for eating disorders when they're overly concerned with their bodies and have internalized the thin-body ideal. Treatment and prevention programs emphasize changing adolescents' views toward thinness and their eating-related behaviors.

Do adolescents get enough exercise? What are the pros and cons of participating in sports in high school?

• Individuals who work out at least three times weekly often have improved physical and mental health. Unfortunately, many high school students do not get enough exercise. • Millions of American boys and girls participate in sports. The benefits of participating in sports include improved physical fitness, enhanced self-esteem, and an understanding about teamwork. The potential costs include injury and abuse of performance-enhancing drugs.

What factors help promote more sophisticated reasoning about moral issues?

• Many factors can promote more sophisticated moral reasoning, including (1) observing others reasoning at more advanced levels; (2) discussing moral issues with peers, teachers, and parents; and (3) being involved in a religious community that connects adolescents to a network of caring peers and adults.

How do physical changes affect adolescents' psychological development?

• Pubertal changes affect adolescents' psychological functioning. Teens, particularly girls, become concerned about their appearance. When forewarned, adolescents respond positively to menarche and spermarche. Adolescents are moodier than children or adults primarily because their moods shift in response to frequent changes in activities and social setting. Early maturation tends to be harmful, especially for girls.

What factors cause the physical changes associated with puberty?

• Pubertal changes take place when the pituitary gland signals the adrenal gland, ovaries, and testes to secrete hormones that initiate physical changes. The timing of puberty is influenced strongly by health and nutrition. Its timing is also influenced by the social environment; for example, puberty occurs earlier for girls who experience stress, harsh punishment, or depression.

How do working memory and processing speed change in adolescence?

• Working memory increases in capacity, and processing speed becomes faster. Both achieve adultlike levels during adolescence.
