School Age (9-12) Flashcards
Physical Changes
- females and males have almost attained their full adult height
Growth
- females are ahead of males in overall growth rate
- females have more body fate and less muscle tissue; response to decreased physical activity and hormonal changes; (females body’s prepare for periods)
- skeletal and muscular structures cause females to be better coordinated, but slower and weaker than males
- more mylelinzation in frontal lobes occurs; they develop logic and planning skills
- selective attention becomes possible (reticular formation)
Immunizations
- HPB and Hep B vaccines are given at this age if missed in infancy
- Healthcare interactions with providers are much more frequent at age 2 than ages 9-12
Why does injury-related mortality increase with age?
- Bc they start to be a little more independent
- They push limits of what they think they are capable of; start taking risks
- higher for males and females
What is the most prominent injury at this age?
- motor vehicle crashes
(>1/2 of injuries are fatal)
Healthy Bodies
- 25% of children (bw 5-11) have unhealthy body weights
- <20% of females and males are overweight
- < 10% of females and makes are obese (highest level recorded)
What is obesity caused by:
- genetic predisposition
- epigenetic modifications set early in life
- environment (overeating, low PA)
- lower SES (lower participation ins sports)
- weight loss is difficult in this age group bc: it requires very specialized diets, their bodies are still developing, diets can have negative impacts both short and long term at this age
3 Risk Factors of Obesity
- over weight parents
- large size for gestation age at birth
- early onset of being overweight (age 5 and under)
What is the relationship between food insecurity and obesity?
- If food insecure, you are likely getting lower quality packaged foods
- there is evidence for associations bw food insecurity and obesity or weight gain in early childhood
Why is food insecurity particularly problematic for children?
- The # of children living in food insecure homes will continue to increase
- Particularly problematic for children because they are learning constantly and it is difficult to learn when hungry
Cognitive Skills
- they develop horizontal decalage
- they develop problem solving rules fro experience and trial and error (not age linked)
Horizontal VS. Vertical Decalage
Horizontal decalage
- Once a child learns a function they didn’t have before, and they apply the skill
○ They apply a skills to all problems
○ Ex. Conservation
Vertical Decalage
- uses same cognitive function in different stages
○ They use the same skill but at different ages
○ Ex. Toddler navigating physical space. When they are 10-12, they can apply the same function to drawing a map at a later age
Relationship bw Conservation and Horizontal Decalage
Conservation applies only to matter whereas horizontal decalage is broader and can apply yo any cognitive function
What is Automaticity?
- ability to recall information from long-term memory without using short-term
memory capacity - achieved through practice
Ex. Putting shoes on and tying shoe laces
- Brushing my teeth
- Speaking
What is expertise?
- more knowledge an individual has about a topic the more efficient their information- processing system will work (despite age)
- advanced skills in one area does not improve general levels of memory or reasoning
Information Processing
3 Skills emerging
- Elaboration
- finding shared meaning or a common referent for 2 or more things that need to be remembered
- when you tack something on to what you already know so you can remember the one thing - Mnemonic
- a device to assist memory - Systematic Searching
- ‘scanning’ one’s memory for the whole domain in which a piece of information might be found
Language
- vocabulary grows by 5,000-10,000 words per year
- by age 8 or 9, they can understand the structure of language, figuring out relationships between categories of words, (ex. b/w adjectives and adverbs)
- At this age, teaching mechanics of grammar is possible
○Developmentally, they can learn it
Literacy
- Balanced Approach: reading instruction that combines explicit phonics instruction with other strategies for helping children acquire literacy
- females read better than boys
