Height and Weight
in Early Childhood |
Avg child grows 2.5"/year (2 important contributors to difference is ethnic origin and nutrition)
Avg child gains 5-7 lbs/year |
|
Brain
|
Between 3-5 yrs old, brain grows 75-90% of adult size
|
|
Reason for brain increase
|
# and size of nerve ednigs within and between brain areas and myelination
|
|
Most brain growth occurs...
|
In the fontal lobes, which are important for planning, organizing new actions and maintaining attn to tasks.
|
|
Motor Development
Gross Motor Skills |
3 yrs old: MOST ENERGY in life; run, jump, hop for the fun of it; s/b able to ride tricycle
4-5 yrs old: Are more confident, more adventurous, they're organized in their motro skills...s/b able to ride bicycle |
|
Motor Development
Fine Motor Skills |
3 yr olds: can pick up small things and place puzzle pieces, but are rough in doing it
4 yr olds develop better fine motor skills: can build towering block towers that are straight 5 yrs olds don't want to build block towers,rather more detailed structures |
|
Nutrition
|
Avg preschooler needs 1700 c a day
BMR (basal metabolism rate) min energy required at rest by person. |
|
Leading cause of deaths in early childhood in the USA
|
car accidents
drownings falls poisenings |
|
Leading cause of deaths world wide
|
dehydration and malnutrition due to diarrhea
|
|
Cognitive Development in Early Childhood
Piaget's Preoperational Stage Overall... |
2-7 years old
Stabel concepts are formed Mental reasoning emerges Egocentrism weakens |
|
Operational skill is to be able to
|
do mentally the opeation before doing it physically
|
|
Two stages of Preoperational 2 substages
|
Symbolic Function: 1st stage
occurs between 2-4 year olds Child is able to represent an object that is not present Intuitive Thought Substage: (the 'why' stage) occurs between 4-7 yr olds. Start using primative reasoning |
|
Piaget's Preoperational substage
Symbolic Function |
-Egocentrism: (terrible twos) Inability to distinguish between one's own perspective and someone els's perspective
Animism: belief that inanimate objects have 'lifelike'qualities and are capable of action |
|
Piaget's Preoperational substage
Intuitive Thought |
Centration-focus, attn centers on one characteristic and exludes all others
Conservation: the awareness tht altering an objects or substances appearances does not change it's basic properties. INABILITY to reverse actions |
|
Vygotsky's Theory of Developement
|
a range of tasks too difficult for children to master alone
|
|
Vygotsky's Theory of Developement
Scaffolding |
like in ZPD use of skilled person to get the task done, and changing the level of support as you go
|
|
Vygotsky's Theory of Developement
Use of Language: Private speech |
talk to self in helping 'self-regulate' in order to be able to plan, guide and monitor.
Important tool for cognitive development, whereas Piaget thought it was egocentric and immature. |
|
Vygotsky's Theory of Developement
Teaching strategies |
-use of ZPD
-use of scaffolding -use of more skilled peers as teachers -monitor and encourage Privatge speech Assess the childs ZPD not IQ |
|
Piaget vs Vygotsky
|
P-more indivudal
V-more collaborative P-ends w/formal op's thought V-end can differ depending on which skills are considred to be the most importan in a particular culture |
|
Information Processing
2 major aspects |
attention and memory
|
|
Information Processing
Attention |
Control of attention: toddlers wander from 1 activity to another, by preschool age, the focus on one item
salient vs. relevent dimensions, planfulness: Salient prop are what stand (clown ex)out and are not necesarily relevant to the solution |
|
Information Processing
Memory |
The retention of info over time is a central process in childrens' development
|
|
Information Processing
Short-term Memory |
retain info up to 30 sec (assuming no rehearsal)
|
|
Information Processing
Memory-Span |
task used to assess short term memory: short list of stimuli are prsented rapidy and recall is measured:
span increased from 2 digits in 2-3 yr olds to 5 in 7 yr olds |
|
Information Processing
Memory How accurate is long-term memory in early childhood? |
With cue and prompts they can remember;
Rehearsal and organization are 2 strategies |
