See How We Grow!

Slow but steady…

• Height changes • Weight changes • Only time in lifespan when on average girls taller than boys • Variation in heights up to 6 inches not unusual

200 Discovering the Lifespan - Robert S. Feldman

Cultural Patterns of Growth

• Sufficient or insufficient nutrition • Disease • Genetic inheritance • Familial stress

Obesity

• Most common causes : – Genetic factors – Lack of physical activity – Unhealthy eating patterns – Combination of these factors • Only in rare cases is being overweight caused by a medical condition such as a hormonal problem

202 Discovering the Lifespan - Robert S. Feldman

Costs of Childhood Obesity

Obese children • More likely to be overweight as adults • Greater risk of heart disease, diabetes, and other diseases

202 Discovering the Lifespan - Robert S. Feldman

The other side of “fat”

• Even very young children are aware of society's fixation on thinness • Lowered self-esteem has been associated with being overweight in girls as young as 5 • Attitude was closely correlated with parents' perceptions

REVIEW

• In middle childhood, height and weight increase gradually.

• Differences in height and weight are influenced by both genetic and social factors.

• Adequate nutrition promotes physical, and cognitive development, while overnutrition and a sedentary lifestyle may lead to obesity.

MOTOR DEVELOPMENT

Discovering the Lifespan - Robert S. Feldman

Gross Motor Development

• Improved muscle coordination

Discovering the Lifespan - Robert S. Feldman

204

Do boys and girls differ in motor skills?

• Gender differences in gross motor skills became increasingly pronounced during middle childhood, – Boys outperform girls – Little or no difference when equal participation in exercise/activities – Influenced by societal expectations

204 Discovering the Lifespan - Robert S. Feldman

Fine Motor Development

• Necessary for wide range of school related tasks • Influenced by increase in amount of myelin  speeds up electrical impulses between neurons

205 Discovering the Lifespan - Robert S. Feldman

Health and School-agers

• Middle childhood is period of robust health • Routine immunizations have produced considerably lower incidence of life threatening illnesses • More than 90 percent of children in middle childhood have at least one serious medical condition but most are short term illnesses

205 Discovering the Lifespan - Robert S. Feldman

Other Health Risks

• Accidents – Motor vehicles – Bikes – Fires and burns – Drowning – Gun-related deaths • Reduced by use of seatbelts and helmets

205 Discovering the Lifespan - Robert S. Feldman

Safety in Cyberspace

• Newest threat to the safety of school-age children comes from Internet and the World Wide Web • Parent and Caregiver Resources: – The Serious Risks of Cyberspace – Child Safety on the Information Highway Risks Online – Safety Net for the Internet: A Parent's Guide

205 Discovering the Lifespan - Robert S. Feldman

PSYCHOLOGICAL DISORDERS

Discovering the Lifespan - Robert S. Feldman

Identifying the Problem

• Psychological disorders in children overlooked for years – Incidence – Symptoms inconsistent from those of adults – Antidepressant drugs used for treatment have never been approved by governmental regulators for use with children

206 Discovering the Lifespan - Robert S. Feldman

Drugs As Treatment

FOR • Depression and other psychological disorders treated successfully using drug • More traditional nondrug therapies that largely employ verbal methods simply are ineffective AGAINST • Long-term effectiveness of antidepressants with children not known • Use of antidepressants on developing brains and long-term consequences more generally not known • Correct dosages for children of given ages or sizes no known

206 Discovering the Lifespan - Robert S. Feldman

Depression

• Key defining features of major depressive disorder in children and adolescents are same as they are for adults • Way symptoms are expressed varies with developmental stage of child

REVIEW

• Gross motor skills continue to improve during the school years.

• Muscular coordination and manipulative skills advance to near-adult levels.

• Threats to safety include accidents, a result of increased independence and mobility, and unsupervised access to cyberspace.

Children with Special Needs

• Visual impairments • Auditory impairments • Speech impairments • Learning disabilities

Discovering the Lifespan - Robert S. Feldman

Do you see what I see?

• Difficulties in seeing – Blindness (20/200 after correction) – Partial sightedness (20/70 after correction)

•

Children with speech-language impairment have an impairment of their speech and/or language structures and functions

•

Parts of the body used in speaking and understanding the brain, nerves, mouth and throat - may be damaged or not developing or working properly

•

Level of speech-language impairment can range from mild to severe

•

Impairment may be obvious before school or not show itself until the child has difficulty learning at school 208 Discovering the Lifespan - Robert S. Feldman

Learning Disabilities Discrepancies Between Achievement and Capacity to Learn

• Difficulties in acquisition and use of listening, speaking, reading, writing, reasoning, or mathematical abilities – 2.8 million children in US – Dyslexia, dysgraphia, dyscalculia – ADD/ADHD

209 Discovering the Lifespan - Robert S. Feldman

The Basic Definition in Individuals with Disabilities Education Act (IDEA)

209 Discovering the Lifespan - Robert S. Feldman

Developmental Writing Disabilities

• Writing involves several brain areas and functions (dysgraphia) • Brain networks for vocabulary, grammar, hand movement, and memory must all be in good working order • Developmental writing disorder may result from problems in any of these areas

209 Discovering the Lifespan - Robert S. Feldman

Developmental Arithmetic Disability

• Arithmetic involves recognizing numbers and symbols, memorizing facts, aligning numbers, and understanding abstract concepts like place value and fractions • Any of these may be difficult for children with developmental arithmetic disorders, also called

dyscalculia 209 Discovering the Lifespan - Robert S. Feldman

What are the most common signs of ADHD?

• Persistent difficulty in finishing tasks, following instructions, and organizing work • Inability to watch an entire television program • Frequent interruption of others or excessive talking • Tendency to jump into a task before hearing all the instructions. • Difficulty in waiting or remaining seated • Fidgeting, squirming

209 Discovering the Lifespan - Robert S. Feldman

ADHD Treatment Controversy

• Ritalin or Dexadrine reduce activity levels in hyperactive children and are routinely prescribe – Effective in increasing attention span and compliance BUT side effects considerable and long-term health consequences unclear – Help scholastic performance in short run BUT long-term evidence for continuing improvement is mixed

210 Discovering the Lifespan - Robert S. Feldman

Are there other treatments for ADD/ADHD?

• Behavioral therapy • Diet
