Chapter 10:
Physical and Cognitive Development in Middle and Late Childhood
Physical Changes and Health
During middle and late childhood:
Growth averages 2-3 inches per year
Weight gain averages 5-7 lbs each year
Baby fat decreases
Muscle mass and strength gradually increase
Less noticeable is ossification of bones
Fine motor skills improve
Myelination of CNS increases
Boys have a greater number of muscle cells and are stronger than girls
Most noticeable physical changes are in head and waist
circumference, and leg length in
relation to body
By age 10-12, manipulative writing skills show (like adults) and ability to master complex skills
Girls usually outperform boys in fine motor skills
Today, too much time is spent watching TV, on computers, and playing video games
Children need more exercise
More children become involved in sports every year; communities and schools are offering more sports
Sports participation is positive and negative with concerns about pressure to win and exploitation
Middle and late childhood
Is usually a time of excellent health
Motor vehicle accidents are most common cause of severe injury
Cancer is 2nd leading cause of death
Most common child cancer is leukemia
Obesity:
Prevalent in children, mostly ages 6 to 11
6-year-old has 25% risk of being obese adult
12-year-old has 75% risk of being obese adult
Linked to lack of exercise
A risk factor for other medical and psychological problems
Context in which child eats can influence eating habits and weight
Low self-esteem, depression, and teasing by peers are common
Children with Disabilities
About 5 million (10%) U.S. children have a disability and receive special education or related services
More than 50% of these have learning disabilities
Learning disability has 3 criteria:
Exclusionary criteria
IQachievement discrepancy
Specificity of learning problem
Learning disabilities
Boys are identified three times more frequently
than girls
Most common form involves reading
ADHD
Inattention, hyperactivity, and impulsivity
Occurs 4-9 times more often in boys
Signs may appear in preschool years
Usually identified in elementary years
About 85% to 90% of children with ADHD take medications such as Ritalin
1970s: Laws passed requiring all public schools to serve disabled children
1975 Public Law 94-142, was renamed Individuals with Disabilities Education Act (IDEA) in 1990
Law requires disability students receive
IEP: Individualized education plans
LRE: Least restrictive environment setting
Inclusion in full-time, regular classroom
Cognitive Changes
Piaget: preschool child is preoperational, thought is still flawed and not well organized
Piaget provided a sound conceptual framework for viewing learning and education emphasizing:
Take a constructivist approach
Facilitate rather than direct learning
Consider childs knowledge, level of thinking
Promote childs intellectual health
Make classrooms exploration/discovery settings
Classification: An Important Ability in Concrete Operational Thought
Neo-Piagetians suggest more emphasis on how children process information
During middle and late childhood
Information processing changes include memory, metacognition, and critical and creative thinking
Short-term memory increases quickly before age 7
Long-term memory increases; expertise depends on learning activities and strategies used
Two important strategies: creating mental images and elaborating on information
Critical thinking: thinking reflectively and productively, and evaluating evidence
Creative thinking: ability to think in novel and unusual ways, devise unique solutions
Convergent thinking
Divergent thinking
Strategies for fostering creativity:
Brainstorming
Provide environments that stimulate creativity
Dont overcontrol
Encourage internal motivation
Foster flexible and playful thinking
Introduce children to creative people
Metacognition: knowing about knowing and learning
Intelligence: problem-solving skills, ability to learn
Intelligence tests:
Binet Tests (early 1900s): IQ is MA divided by CA and multiplied by 100
Stanford-Binet Test, revised Binet Tests, led to creation of bell curve
Wechsler Scales: verbal & nonverbal
WPPSI-R: ages 4 to 6.5 years
WISC-III: ages 6 to 16 years
WAIS-III: adults
Thurstone: 7 types of primary abilities exist:
verbal comprehension, word fluency, spatial
visualization, number ability, associative
memory, reasoning, and perceptual speed
Gardner: 8 types of intelligence
verbal, mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalist
There is great debate over what qualifies as a type of intelligence and how to assess it
Controversies and issues in intelligence:
Heredity and genetics versus environment
Flynn effect
Bell curve: U.S. is developing large underclass of intellectually deprived
Racial and cultural bias
Use and misuse of IQ tests
Classifying types of mental retardation
Classification as being gifted
Language Development
Language during middle and late childhood:
Changes occur in how words are selected
Increased logical reasoning/analytical skills
Increased ability to understand and use complex grammar
How to respond to fact that words are understood before child learns to read them?
Whole-language approach
Basic-skills-and-phonics approach
Guided oral reading also recommended
Bilingualism:
Learning a 2nd language is easiest for children
Ability to speak 2 languages has positive effect on childs cognitive development and performance on tests in
Control of attention (focus)
Concept formation
Analytic reasoning
Cognitive flexibility
Cognitive complexity
