Early Childhood/preschool Flashcards
What is a common issue for children (ears)?
Earaches
-eustachian tube
Obesity
Body weight more than 20% higher than average weight for a person of a particular age and height
Causes of obesity
More time watching tv, computer, less time spent on play and exercise now
Optimal strategy against obesity
Have a variety of low-fat and high-nutrition foods available for preschoolers
-high iron important
What is the greatest risk for death or injury in preschoolers?
Accidents.
Injury is the leading cause of death
55% of injuries during sport or activity
73% of injuries at home
Boys take more risks, so higher injuries
Don’t have executive functioning yet to be able to understand consequences of actions
Early education options
More than 50% of children 1-5 are in some form of care outside the home
- child care
- family run child care
- preschool
Characteristics of high quality care
- well trained
- appropriate ratio of care providers to children (1:5 max)
- carefully planned curriculum
- rich language environment
2 important brain developments
1) number of interconnections increase - facilitates the acquisition of cognitive skills
2) the amount of myelin increases- facilitates speed of neural processing
Size of brain compared to adults
Brain is 80% of adult
At age 5, brain is 90% of the weight of adult brain, but there body is only 30% of an adult’s body
Brain lateralization
Corpus callosum thickens, coordinates two hemispheres
Lateralizations: each hemisphere specializes
- Left is verbal tasks, processing info sequentially
- Right is nonverbal tasks
Growth in children in high and low SES homes
High SES- growth in typical a manner
Low SES- divergences in growth, slower growth because less resources
Left handedness in relation to brain lateralization
10% left handed, most males
Of left-handed, most still demonstrated left hemispheric language lateralization
Gross motor skills
Can now engage in activities that require a high degree of coordination (ex. Bike, ski)
Boys-more muscle strength
Girls- better limb coordination
What two things play a role in skill development
Practice and brain development
Toilet training- when to start
When they are ready! Physically and emotionally
Signs of readiness:
- staying dry 2+ hours during the day
- can indicate when they have to go
- can undress alone
- waking up dry after naps
Fine motor skills
Involve delicate and smaller body movements (ex. Using a spoon)
These skills require practice
Start showing fine motor skills as early as 8 weeks
Perceptual development
Detecting boundaries between colours (3-4 years old)
Many are far-sighted, unable to see close up well. By first grade, eyes focus. Far sighted because head shape is still developing
Now nearsightedness is becoming more of a problem since we use phones and computers all the time
Piaget’s stages of cognitive development
1) sensorimotor
- birth to 2 years
- use sensory and motor schemes to act on world
2) preoperational
- 2 to 7
- acquire symbolic schemes such as language and fantasy
3) concrete operational
- 7 to 11
- think logically and solve problems
4) Formal operational
- 11 + years
- logically about abstract ideas and hypothetical situations
Preoperational stage
- before this they acquire symbolic function
- use symbols proficiently
- difficulty thinking logically
- at 2 or 3 they begin to pretend in their play
6 types of play
1) sensorimotor (12 months)
2) constructive play (2 years- stack up blocks, build something)
3) first pretend play (15-21 months) Toy is used for its actual purpose
4) substitute pretend play (2-3 years) pick up broom and pretend it is a horse
5) sociodramatic play- (preschool years) Imaginary friends
6) Rule governed play- (5 or 6 years) assigning roles more logically, boy is father, small friend is baby
Egocentrism
Belief that everyone sees and experiences the world the way they do
Centration
Tendency among young children to think of the world in terms of one variable at a time
Conservation
The understanding that matter can change in appearance without changing in quantity
- identity: realize it maintains the same if nothing is added or subtracted
- compensation: changes in one dimension can be offset by changes in another
- reversibility: the change can be cancelled out by reversing the steps
Criticisms of piaget’s theory: Egocentrism and perspective taking
Children as young as 14.5 months have some ability to understand that other people experience things differently to them
By 2 or 3, can adapt play to the demands of friend
Info processing: understanding of numbers
Average preschooler can count
Info processing: autobiographical memory
Becomes increasingly accurate throughout preschool years
- memories must be salient to be remembered
- memories organized into scripts (representations of events in order that they occurred)
Forensic developmental psychology
Field that focuses on the reliability of children’s autobiographical memories in a legal context
Long term vs short term memory
Long term- relatively permanent and unlimited type of memory
Short term
- retention of info for up to 15-30 seconds without rehearsal of info
- individuals can retain info longer using rehearsal
Working memory
- mental workbench where we manipulate and assemble info when making decisions, problem solving and comprehending written and spoken language
More active in modifying info than short term memory is
Parts of the working memory model
Central executive- control and regulation
Phonological loop- verbal info
- list of similar words is harder to remember
- rehearsal helps memory
Visuospatial sketch pad
- holds info about what we see
- tasks that involve working your way through complex building
Episodic buffer
-links info across domains
Attention
Ability to control and sustain attention related to school readiness
Attention to relevant info increases in school years
Older children are better at shifting attention from one thing to another as needed
Multitasking is linked to
Use of multiple electronic media
If task is complex and challenging, multitasking reduces attention to key task
Sociocultural theory: 4 stages of cognitive development
1) primitive stage
- learns primarily through conditioning until language develops
2) naive psychology phase
- learns to use language to communicate, but still doesn’t completely understand symbols
3) egocentric speech
- uses language as a guide to solving problems
4) Ingrowth stage
- internalization of speech routines
Evaluations of vygotsky’s sociocultural theory
- not enough evidence to support or contradict it
- theory may ignore important contributions of individuals to group interactions
Theory of Mind
the ability to understand what others are thinking
How is theory of mind assessed?
Using a false belief task
(anne has a marble and puts it in a box, then leaves the room. Mary comes and moves the marble to the cupboard. Where will anne look for it?)
3 year olds say she will go to original spot (fail)
4 year olds understand it
