Development Flashcards
Stages of development
Prenatal (conception until birth)
Childhood (birth until 12yrs)
Adolescence(13-19yrs)
Arulthood(20yrs until death)
Stages of brain development - Pre-natal
1st trimester - cerebral cortex forms and divides into frontal lobe temporal lobe parietal lobe and occipital lobe
2nd trimester
Brain becomes fully developed synapses form and neurons can interact
3rd trimester
The brain continues to grow
Stages of brain development - childhood
After birth new neuron connections begin to form and things such a prefrontal codex peak so we have memory and can start to understand cause and effect we also start loosing meaning less connections
Stages of brain development - adolescents
Grey matter reaches maximum density
Limbic system matures first which regulates emotion and helps form new memories
Prefrontal cortex matures last regulates desision making
Stages of brain development - adulthood
At 25 prefronal cortex finally matures making rational desision and focusing on long term goals
During later adulthood can get things such as altzimers which can effect brain structure
Piagets theory of cognitive development
It has 4 stages
Invarient children pass through them in the same order
Universal
Scheme- pictures of the world in there mind to help them learn how to react
Assimilation - new information encorperated into an existing schema
Accommodation- new information is used to alter or create a new schema
Stages of cognative development - Sensory motor stage
Age 0-2
Object perminance - learning that just because something isn’t in sight it still exists
Stages of cognative development - pre - operational stage
Age 2-7
Animism - belife that inanimate objects have feelings
Egocentrism - belife that everyone sees the world how they do(the three mountain problem)
Reversibility - unable to think about things in reverse order or somthing returning to original state
Stages of cognative development - concrete operational
Age 7-11
Concervation - changing shape dosnt change volume mass or length (Concervation experiments)
Decentration- ability to focus on more than one aspect of a situation
Seriation- put things in rank order
Linguistic humour - playing with words to create jokes /humour
Stages of cognative development - concrete operational
Age 7-11
Concervation - changing shape dosnt change volume mass or length (Concervation experiments)
Decentration- ability to focus on more than one aspect of a situation
Seriation- put things in rank order
Linguistic humour - playing with words to create jokes /humour
Stages of cognative development -formal operational
Age 11+
Hypothetical thinking - Abstract thinking
Think more logically
Can comprehend and contrast diffrent ideas
Stages of cognative development - criticisms
Under estimating the age at which children can achieve different parts of the stages
Researchers have shown that only around half of adults reach formal operational stage with many not being capable of abstract thinking
Piaget describes the diffrent stages but dosnt explain how these stages actually occur and what changes the child’s thinking
Some of his work is too complicated for children to understand
Piagets theory can be considered reductionist because he didn’t take into account the important role teachers have in children’s learning
Piaget conservation of number - aim + Hypothesis
Aim
Demonstrate children in concrete operational stage are more likely to conserve than those in the pro operational stage
Hypothesis
concrete operational stage will be able to conserve those in pre operational will not
Piaget conservation of number - method
Natural experiment and iv was naturally occurring (child age)
Dv Ability to conserve number
Cross sectional study
Independent measures
Sample
Small sample of school children from Geneva
Included 3 of his children
Procedure
Shown 2 rows of counters lined up then spread 2nd row then asked if there’s the same number of counters
Piaget conservation of number -results and conclusion
3-4 pre operational stage said more in second row
5-6 end of pre operational some could say number the same but not that the length had changed
Concrete operational could recognise they had the same and explain why
Conclusion
Hypothesis is supported children in concrete operational are more likly to be able to conserve number and more likely to be able to justify their answer
