Chapters 11/12/13 Flashcards
11.1 Patterns of Growth in Middle Childhood
- 2 inches per year (boys and girls), doesn’t vary until growth spurt
- average weight gain between 6-12 years is 5-7 pounds per year
- become less stocky and more slender
- growing pains
- adult teeth grow in
growth spurt
period during which growth advances at a dramatically rapid rate compared with other periods
11.1 Brain Development
- myelation continues
- frontal cortex still developing-gaining control of the situation
11.1 Nutrition and Growth
- body weight doubles
- more play/exercise; need more calories per day (2,000)
- poverty=worse diets
- food pyramid
11.1 Gender Differences in Growth Patterns
- 9/10 boys are heavier and taller than girls
- girls spurt first and pass boys
- boys spurt at 13/14
- increase in muscular strength for both
- males=muscle tissue growth, females=fatty tissue growth at age 11
11.1 Vision and Hearing Development
- nearsighted=25% of kids, 60% of young adults
- ear infections=6-12 years old not as likely as 5 and under kids
11.2 Overweight Kids in the US
- 16-25% of children and teens
- doubled in the last 20 years, Latino boys, African American girls are more likely
- high blood pressure, high cholesterol, diabetes, and respiratory problems
- overweight kids tend to become overweight adults
- low self-image, depression, and anxiety, less liked by peers
11.2 Causes of Being Overweight
- heredity=tendency to burn up extra calories or turn extra calories into fat
- high sugar, unhealthy foods, and low physical activity
- amount of fat cells, environmental influences, amount of TV, stressors, and emotional reactions
11.3 Prevalence of Asthma
more likely in wealthy nations
11.3 Factors that Increase Asthma
respiratory infections and skin imitations, family history, and lower socioeconomic status
11.3 Treatment of Asthma
corticosteroids, removing of dust, and it may improve with age
11.4 Gross Motor Skills
- steady improvement; group games and sports, balance, coordination, and strength
- muscles growing, increasing myelation, gradually increased reaction time
reaction time
amount of time required to respond to a stimulus, individual differences can be huge
11.4 Fine Motor Skills
keep improving; zippers, buttons, forks and knives
11.4 Gender Differences in Motor Development
- boys have greater overall strength
- girls have grater limb coordination and overall flexibility
- boys are shown more support and more likely to participate in sports
- physical active decreases with age (both genders)
11.4 Children in the US and Motor Development
- 2/3 of children are not physically fit
- TV and sports that are not physically intense
11.4 How to Improve Physical Fitness
- encouragement from role models, family activities, decrease TV time, and increase outdoor play
- focus on physical fitness, not winning
11.5 ADHD
- behavior disorder characterized by excessive inattention, impulsiveness, and hyperactivity
- onset occurs by age 7, for at least 6 months of persistent symptoms, impair function in school, and difficulty getting along with others
- 11% of children, twice as often for boys
11.5 Is ADHD Over-Diagnosed?
many professionals believe so; medication is misused
11.5 Causes of ADHD
- run in families
- how bring processes dopamine and serotonin
- coexists with anxiety disorders
- brain chemistry is different-failure to exercise adequate inhibitory processes (can’t control impulses)
stimulants
- drugs that increase the activity of the nervous system
- blocks reuptake of dopamine and noradrenaline
11.5 Treatment of ADHD
- stimulants
- cognitive behavioral therapy=increase self control and problem solving abilities
learning disability
groups of disorders characterized by inadequate development of specific academic, language, and speech skills
