Chapter 7. Flashcards
Physical changes between age 2-6
Slower and less dramatic changes than in infancy. Changes in height and weight are much slower.
Average growth is 2.5 inches and 5 to 10 pounds per year during early childhood.
Growth patterns vary individually.
Etnicity and nutrition effects height a lot.
Tooth Development in early childhood
Appearance of first tooth=proper dental care.
Healthy primary teeth helps to support the development of healthy permanent teeth.
Motor development - gross motor skills. What are they required for?
Are required to stay
upright and move around.
Preschool children and motor development
Preschool children make steady progress in motor development. Mostly gain large muscle skils.
Most preschool children are more
active than at any later period in the life span.
Children’s motor activity levels increase linearly with age and tend to peak between 7 and 9 years of age—
later than previously thought.
Motor development at different ages
Age 3: Simple movements such as running, hopping, jumping.
Age 4: Athletic movements at home and school.
Age 5: Adventurous, stunts in gyms and on playground equipment.
Brain development and motor skills
Brain maturation, motivation, and guided practice make gross motor skills possible.
Influence of culture, urbanization, and locale is important.
Why is motor activity important?
Children who exhibit higher motor activity levels demonstrate
* better ability to control or inhibit their behavior.
* allowing for successful task achievement.
Extraneous motor activity is an important form of exploratory behavior.
Fine motor skills
Small hand and finger movements.
More difficult to master than gross
motor skills.
Small muscle groups and fine motor skills - improve in early childhood.
Often involve both sides of the brain.
Are influenced by practice and. maturation.
(On average, mature 6 months earlier in females.)
Adult encouragement and practice are important and cultural context influence expression.
All forms of artistic expression blossom during early childhood - In every artistic domain skill comes gradually with practice and maturation.
Fine motor skills development through the years
Fine motor skills are:
Age 3: Still clumsy
Age 4: Improved fine motor coordination.
Drawing as a fine motor skill
The origins of writing start with the stages of drawing:
Age 2: Basic Scribble
Age 3: Shape Stage
Age 4: Design Stage
Age 4-5: Pictorial Stage
What is lateralization?
Brain functions are divided between the two hemispheres of the cerebral cortex.
Genes provide the mechanism for lateralization but experience shapes the pace.
– Preschoolers with the most advanced language skills show the highest levels of left-sided lateralization. (But is it cause or effect?)
– Language is primarily centred in the left brain (95% of humans)
What is the corpus callosum?
The brain structure through which the left and right sides of the cerebral cortex communicate.
Grows and matures more in early childhood than in any other period of life.
When does a preference for a certain hand develop?
Handedness: is a strong preference for using one hand or the other.
Develops between 2 and 6 years of age.
Right handedness is a dominant gene. (If both parents are right-handed - 92% chance of being right-
handed, too)
Today, about 12% of the population identify as left-handed.
Are there developmental consequences to being left-handed?
There are some correlations with language processing differences
There are some correlations with health issues, including migraines and allergies.
But there may also be advantages - math and artistic abilities, as well as athletic and musical abilities
(Being a ‘lefty’ was once seen as a posing problems.)
Brain development during early childhood
Brain growth, synapse formation, and myelination continue in early childhood, although at a pace slower than in infancy.
Age 6: brain reaches 95 percent of adult volume.
Children’s brains undergo rapid, distinct spurts of growth, especially in the frontal lobes.
Contextual factors, such as poverty and parenting quality, affect brain development.
New and extensive myelination - lead to faster thinking
Maturation of the hippocampus
probably accounts for improvements in memory function across the preschool years.
Maturation of prefrontal cortex
Myelination
Nerve cells are covered and insulated
with a layer of fat cells that speeds signals between neurons.
Increases the speed and efficiency at which information travels through the nervous system.
Primary reason for faster thinking observed in young children is new and extensive myelination.
Maturation of the hippocampus
Leads to improvements in memory.
The hippocampus plays a role in the transfer of information to long- term storage.
Infantile Amnesia
Most don’t remember anything before 3 years of age.
Inability of adults and older children to remember more than a few events that took place before they were 3
years of age.
Maturation of prefrontal cortex:
Prefrontal cortex: planning, thinking, social awareness and language occur.
There are notable neurological changes between ages 2 and 6. (Especially noticeable in areas of the cortex.)
Maturation of prefrontal cortex facilitates:
* Focused attention
* Reduced Impulsiveness
* (Neurological immaturity is another reason adults need to prevent childhood injury.)
What should young children be eating?
Preschoolers need to eat less per kilogram than infants and toddlers.
A well- balanced diet, including limiting sugar and fat intake. (Tallriksmodellen)
Conflicts between young children and their parents often focus on eating behaviours.
What factors contribute to childhood obesity?
Family income.
Poor nutrition.
Genetics may also play a role.
social influences and context can contribute to obesity in individuals or populations.
Poor eating habits formed when young may lead to later obesity - 12% of children aged 2 to 5 are now overweight or obese.
Childhood obesity is one of the most serious public health challenges of the twenty-first century.
How much sleep should children get in early childhood?
Recommended sleep: 10 to 13 hours each night without interruption.
Amount of sleep decreases as children grow. –Most children give up naps around 4 years of age.
What sleep issues are common in early childhood?
struggles can occur –consistent bedtime routine required.
Some children have sleep disturbances such as:
–nightmares
–night terrors
–sleep walking
–bedwetting
–narcolepsy
–insomnia (20-40%)
More daily screen time is
associated with a decrease in sleep time.
Picky eaters
Generally take in adequate food for growth.
Encourage children to be open-minded about food by offering choices; offer new foods one at a time in small amounts.
