Middle & Late Childhood: Physical & Cognitive Development Flashcards
How is physical growth in middle & late childhood characterized?
- Slow and consistent
- Period of calm before the rapid growth spurt in adolescence
During elementary school years, children grow an average of _____ inches a year until 11 years old and gain about _____ pounds a year
- 2-3 inches
- 5-7 pounds
Average height & weight of 8-year-old children:
- Height: 4 ft. 2 inches
- Weight: 56 pounds
Weight increase is due mainly to increases in the size of? With this increase comes the decrease of?
- Skeletal and muscular systems -> Increased muscle mass & strength
- Some body organs
- Baby fat decreases
Changes in proportion are among the most pronounced physical changes in middle and late childhood
These decrease in relation to body height
- Head circumference
- Waist cirumference
- Leg length
- The highest level of the frontal lobes that is involved in improved attention, reasoning, decision making, and self-control
- Its brain pathways an circuitry continue to increase in middle and late childhood
- Orchestrates the functions of many other brain regions during development
Prefrontal cortex
The brain is _____ organized and mainly develops from the ______
Hierarchically organized; bottom up
What does increased focal brain activation and synaptic pruning from 7-30 years of age entail?
Increased efficiency in cognitive performance, especialy cognitive control
It thickens at temporal and frontal lobe areas for language abilities such as reading
Cerebral cortex
What generally happens to motor skill development in middle-late childhood?
- Become smoother and more coordinated
- Physical skills (running, climbing, swimming, etc.) are further developed and mastered
Which gender outperforms in gross motor skills? Fine motor skills?
- Boys outperform in gross motor skills
- Girls outperform in fine motor skills
Long-term negative effects of undeveloped basic motor skills:
- Unable to participate in group activities or sports
- Lower motivation for sports participation
- Lower self worth
One way of encouraging children to be active and develop their motor skills
Organized sports
It is reflected in regards to the brain in the improvement of fine motor skills during middle and late childhood
Increased myelination of the central nervous system
Fine motor-skill milestones at
- 6 years
- 7 years
- 8-10 years
- 10-12 years
- 6 years: Hands as tools - hammer, paste, tie shoes, fasten clothes
- 7 years: Steadier handedness; writes with pencil in smaller print; reversal of letters less common
- 8-10 years: Use hands independently with more ease and precision; now write rather than print
- 10-12 years: Manipulative skills; playing instruments, crafts
Guidelines recommend how much time young children get for physical activity
15 or more minutes per hour, totaling to 3 hours per day
This exercise benefits cognitive development: children’s attention, memory, effortful and goal-directed thinking and behavior, and creativity
Aerobic Exercise
_____ and _____ play important roles in determining children’s exercise levels
Parents and schools
This is linked to low activity and obesity; children linked to gadgets instead of being active
Screen time
Although the dangers of disease have greatly diminished, parents must still keep a timely _____
Immunization schedule
Leading cause of death during childhood
Accidents, specifically motor vehicle accidents either as passenger or pedestrian
What is the best way to improve the health of children who live in poverty?
Treat the medical problems of the entire family, not just the individual child
Categories for obesity, overweight and risk of being overweight are determined by
Determining body mass index (BMI), formula that takes into account height and weight
Categories & BMI Correlation:
Obese: 97th percentile >
Overweight: 95th percentile >
Risk of becoming overweight: 85th percentile >
Causes of obesity:
- Heredity
- Environment
Consequences of Obesity
Medical & psychological problems
- Pulmonary problems
- Hip problems
- Type 2 diabetes
- Hypertension / high blood pressure
- Elevated blood cholesterol
- Depression & anxiety
- Low self-estee
Interventions for Obesity:
Combination of
- Diet
- Exercise
- Behavior modification
- It is uncommon but can sow the seeds in adulthood
- Associated with metabolic syndrome
- Possess one or more of the risk factors (HTN, Obesity)
Cardiovascular Disease
Metabolic Syndrome is characterized by what factors?
- High BMI
- High waist circumference
It is the second leading cause of death of children aged 5-14
Cancer
Some types:
- Leukemia (most common),
- Brain,
- Bone,
- Lymph system,
- Muscles,
- Kidneys,
- Nervous system
Advancement in cancer treatment
Chemotherapy
How is a child with a learning disability defined?
A child with a learning disability has difficulty in learning that involves understanding or using spoken or written language.
The difficulty can appear in
- listening,
- thinking,
- reading,
- writing,
- doing mathematics
About three times as many boys as girls are classified as having a learning disability. Among the explanations for this gender difference are:
- Greater biological vulnerability among boys
- Referral bias - boys are more likely than girls to be referred by teachers for treatment because of troublesome behavior
What are the 3 types of learning disabilities:
- Dyslexia: individuals with a severe impairment in their ability to read and spell
- Dysgraphia: involves difficulty in handwriting. Children with dysgraphia may write very slowly, their writing products may be virtually illegible, and they may make numerous spelling errors because of their inability to match up sounds and letters
- Dyscalculia: aka developmental arithmetic disorder, is a learning disability that involves difficulty in math computation
Interventions for Learning Disabilities:
- Improving reading ability
- Intensive instructions by teacher
What does ADHD stand for? What characteristics are portrayed by children who usually have it?
Attention Deficit Hyperactivity Disorder
Characteristics portrayed:
- Inattention: Children who are inattentive have so much difficulty focusing on any one thing that they may get bored with a task after only a few minutes—or even seconds
- Hyperactivity: Children who are hyperactive show high levels of physical activity, seeming to be almost constantly in motion
- Impulsivity: Children who are impulsive have difficulty curbing their reactions; they do not do a good job of thinking before they act
Depending on the characteristics that children with ADHD display, they can be diagnosed as:
- ADHD with predominantly inattention
- ADHD with predominantly hyperactivity/impulsivity
- ADHD with both inattention and hyperactivity/impulsivity
Controversies & Risks of ADHD:
- Boys diagnosed more than girls four to nine times
- Increased diagnosis may be because of incorrect diagnoses
- Increased risk of school dropout, adolescent pregnancy, substance use, antisocial
Causes of ADHD:
Not definite, but some include:
- Brain Image: Delayed peak thickness in cerebral cortex at prefrontal regions
- Heredity
- Prenatal/Postnatal brain damage
- Cigarette and alcohol exposure
- High level of maternal stress during prenatal
- Low birth weight
Strategies for ADHD treatment:
- Stimulant drug treatment
- Behavior management
- Neurofeedback
- Mindfulness training
- Exercise
Method that trains individuals to become more aware of their physiological responses so that they can attain better control over their brain’s prefrontal cortex
Neurofeedback
