Chapter 9. Flashcards
Late childhood
6-11 years: Period between early childhood and early adolescence.
The healthiest years of the life span.
Slow, consistent growth is seen in middle and late childhood.
- Growth averages 2 to 3 inches per year.
- Weight gain averages 5 to 7 pounds per year.
Head circumference and waist
circumference decrease in relation to body height.
Bones continue to ossify (harden)
Girls in this age range are ahead of boys in their overall rate of growth.
What does improvement of fine motor skills in middle and late childhood result from ?
Fine motor skills: Increased myelination of the central nervous system.
Motor skills: increased size and strength (e.g., at 11 years can throw ball 3 times farther than at 6 years).
Changes in the brain in late childhood
Total brain volume stabilizes.
Significant changes in structures and regions occur, especially in the prefrontal cortex.
Cortical thickness increases.
Brain pathways and circuitry involving the prefrontal cortex, the highest level in the brain, continue to increase.
Generally speaking, how healthy are Canadian children?
Most Canadian children are healthy.
* Middle and late childhood is a time of excellent health.
* Regular medical care remains beneficial.
* Immunization is still an important factor in health
What are risk factors for obesity in middle childhood?
Risk factors for predicting excessive weight gain in childhood:
Overweight parent(s)
Large size for gestational age at birth
Early onset of being overweight (age 5 and under)
Obesity results from many factors:
* Genetic predisposition
* Epigenetic modifications set early in life
* Environment that promotes overeating and/or low activity level
* Lower socioeconomic status is higher risk
* Lower socioeconomic status may result in lower participation in organized sports.
What are the benefits of physical exercise?
Canadian guidelines for positive health outcomes recommends:
* Physical activity: 60 minutes a day or more of moderate to vigorous intensity each day.
* Sedentary behaviour: no more than two hours per day of screen time or other passive non-school related activity).
A higher level of physical activity is linked to a lower level of metabolic disease risk, based on measures of cholesterol, waist circumference, and insulin levels.
Regular physical activity combined with a high level of calcium intake increases bone health.
Body Mass Index (BMI)
Measures the proportion of body fat to lean body mass.
How to get children to exercise more
Have children plan community and school activities.
Encourage families to focus more on physical activity.
Go for a walk or a bike ride together.
Physical activities in school- Gym class in school etc.
Benefits of organized sports
There are physical, socioemotional, and cognitive benefits to participating in organized sports:
- Increases physical fitness
- Teaches cognitive and social skills
*Sport specialization - not necessary
*Coaches should be positive with realistic expectations
What is the first and second leading cause of death in children ages 5-14 in Canada?
Unintentional injury-related deaths are the most common cause of death in Canadian children.
The injury-related mortality rate increases with age and is higher for males than for females.
More than half of the fatal injuries are due to motor vehicle crashes, with drowning being next most common.
Cancer is the second leading cause of death in children who are 5 to 14 years old.
The most common child cancer is leukemia.
Today, children with cancer are surviving longer because of advancements in cancer treatment.
When are children at greatest risk of accidental injury - in the preschool or mid-late childhood years?
Middle years are a greater risk for injury.
They are more mobile and more independent.
The majority of nonfatal unintentional injuries are caused by falls
In Canada, people under the age of 20 accounted for 16 percent of all injury hospitalizations in 2001–2002
What can caregivers/parents do to help children to stay safe?
Parents can help to keep their children safe from accidents by:
- being good role models
- insisting that their children use protective devices
- not overestimating their children’s skills.
In cars: Safety belt restraints and child booster seats are highly recommended.
What are the features of Piaget’s concrete operational stage of cognitive development?
his involves mastering the use of logic in concrete ways. The word concrete refers to that which is tangible; that which can be seen, touched, or experienced directly.
Age 6: most children have some aspects of the concrete operational stage - they know that a lump of play doh has the same mass even if it’s appearance is changed.
Children are becoming less
egocentric; they begin to be able to understand others’ perspective(s).
In this stage children use schemes that enable them to think logically about objects and events in the real world.
What is the difference between inductive and deductive reasoning?
Inductive logic: a type of reasoning in which general principles are inferred from specific experience.
EX: The 3 dogs in my neighborhood are friendly. - Dogs are friendly.
Deductive reasoning: Moves from generalities to specific conclusions.
– EX: All birds have feathers. A robin is a bird. A robin has feathers.
The difference is that in inductive logic the conclusion comes from experience and in deductive reasoning it comes from a logically drawn conclusion.
Under what conditions can children in mid-ate childhood use deductive reasoning?
Children in the concrete operational stage can use deductive reasoning - but it is still not strong; so it is difficult for children.
They can generally only use deductive logic when the questions are fact based.
(Understands the gray elefant bot not the polka elephant)
How do researchers and theorists working today view Piaget’s concrete operational stage?
Neo-Piagetians: developmentalists who argue Piaget was partially correct, but his theory needs considerable revision.
They elaborated on Piaget’s theory, increasing the emphasis on information processing, strategies, and precise cognitive steps.
Concrete operations
Immensely powerful schemes that include the mental operations of:
– addition
– subtraction
– reversibility
– decentration
Concrete Operational Stage-
Decentration
Thinking that takes multiple variables into account.
The ability to pay attention to multiple attributes of an object or situation rather than being locked into attending to only a single attribute.
(EX: hight, length and width)
Concrete Operational Stage
- Seriation
The concrete operation the involves ordering stimuli along a quantitative dimension (for example, length).
Involves the ability to put things in order based on quantity or magnitude.
Concrete Operational Stage - Reversibility
The understanding that both physical actions and mental operations can be reversed.
The fact that a process, an action or a disease can be changed so that something returns to its original state or situation.
(Understanding hierarchies depends on this)
Concrete Operational Stage
- Transitivity
The ability to logically combine relations to understand certain
conclusions.
When a child is presented with the information “A” is greater than “B” and “B” is greater than “C”.
Classification
This means children can classify objects into groups and subgroups. For example, they can group objects based on color, shape, or similarities.
EX: The child understands that someone can be a son, a father and a brother all at the same time.
An important component of concrete thought.
Inductive logic - concrete operational stage
- Inductive logic: a type of reasoning in which general principles are inferred from specific experience.
EX: The 3 dogs in my neighborhood are friendly. - Dogs are friendly.
In the concrete operational stage children can use some forms of logic (but not others).
Increased skill in inductive logic allows the child to go from a specific experience to a general principle.
EX of inductive reasoning:
I see fireflies in my backyard every summer. - Hypothesis: This summer, I will probably see fireflies in my backyard.
Data: I tend to catch colds when people around me are sick.
Hypothesis: Colds are infectious.
Deductive logic
Moves from generalities to specific conclusions.
– EX: All birds have feathers. A robin is a bird. A robin has feathers.
– EX: All mammals have kidneys.
Dolphins are mammals. Dolphins have kidneys.
Siegler
Suggests there are no stages, only sequences.
– Problem-solving rules emerge from experience and trial and error rather than being specifically linked to age.
How do attention and memory develop during mid-late childhood?
During middle and late childhood, most children dramatically improve their ability to sustain and control attention.
They pay more attention to task-relevant stimuli than to salient stimuli.
Other changes in information processing involve memory, thinking, metacognition, and executive function.
What is automaticity? Why is it important?
The ability to recall information from long-term memory without using short-term memory capacity.
– Is achieved primarily through practice.
Very important !! - It allows for more efficient processing.
How does expertise shape information processing (memory, attention)?
Knowledge and expertise: Experts have acquired extensive knowledge about a particular content area.
Older children usually have more expertise about a subject than younger children do. (EX 10 year old chess player).
This can contribute to better memory for the subject.
The more knowledge a person has about a topic, the more efficiently their information-processing system work will work, despite age.
More information about something = enhanced longterm memory.
(Advanced skill in one area does not improve general levels of memory or reasoning.)
What is creativity?
Creative thinking is the ability to think in novel and unusual ways.
Coming up with unique solutions to problems.
Parts of creative thinking:
Brainstorming
Divergent thinking
Convergent thinking
Metacognition
Working memory
A mental “workbench” where individuals manipulate and assemble information when making decisions, solving problems, and comprehending language.
Uses information from long-term memory in its work; and transmits information to long-term memory for longer storage.
Processing efficiency
The ability to make efficient use of short-term memory capacity increases steadily with age.
Long-term memory
A relatively permanent type of memory that holds huge amounts of information for a long period of time.
Increases with age during middle and late childhood.
Strategies
Deliberate mental activities that
improve the processing of information.
Improvements in memory reflect children’s increased knowledge and use of strategies.
Elaboration
Engaging in more extensive processing of information.
Finding shared meaning or a common referent for two or more things that need to be remembered.
A learning strategy that supports students in making connections between new material and what they already know.
Encourage them to engage in mental imagery.
Motivate them to understand rather than memorize.
Repeat with variation, and link early and often.
Embed memory-relevant language.
Mindfulness (critical thinking)
One important aspect of critical thinking is mindfulness: being alert, mentally present, and cognitively flexible.
Mindfulness training has been found to improve children’s attention self- regulation.
Critical thinking involves thinking reflectively and productively, and evaluating evidence.
Brainstorming
A process in which individuals come up with creative ideas in a group and play off each other’s ideas.
