development Flashcards
early brain development
how the brain develops in the womb and matures
brain stem
-most highly developed part of the brain at birth
-connects brain to spinal cord
-autonomic functions
cerebellum
-matures late
-near the top of the spinal cord
-co-ordintes sensory and motor
thalamus
-deep inside the brain in each hemisphere
-information hub, recieve indo and send signals around the brain
cortex
-very thin folded cover
-thinking + processing in the forntal cortex
-forntal, visual, auditory, motor areas in each hemisphere
nautre
inherited
nurture
environmantla influences on dvevelopment
smoking
smoking during pregnancy can lead to smaller brains
infection
in the womb german measles can lead to hearing loss
voices
babies learn to recognise mothers voice
intercation between nature and nurture
the brain forms dure to nature but the environment had a major influence even in the womb
piagets theory of cognitive development
the way a persons knowlwdge, thinking and intellifgence changes as they get older
-children think differentl;y from adults
schemas
a mental structure conitaining all of the information we have learnt about one aspect of the world
schemas
-children are born with a small nukber of schemas
-gradually we get more schemas that bget more complex through the process of assimilation and accomadation
assimilation
takes place when we understand a new experience and add that new information to our existing schema
accomadation
we need to aquire a new schema to deal with knowledge that we have learnt about the world
piaget cognitive development evalutaion
=weakness
-smaple was not representative
-used children form academic families in other families this may nit be the case
-cannot be genaralised for everyone
piaget cognitive development evalutaion
=strength
-led to enormous amount of researchers to test his idea
-helped impove our undertsnading of how childrens thinking develops
piagets therory of conservation
although the appearnce changes quantity stays the same piaget showed younger children cant conserve quantities ‘naughty teddy study’
mcgarrigle and donaldson
aim
to see whether the childs raection would be different if there was no deliberate change in the row of counters
mcgarrigle and donaldson
method
children ages 4 to 6
2 rows of cpunters and teddy messed up one of them
child asked if rows were the same
mcgarrigle and donaldson
results + conclusion
-deliberate change = 41% conserved
accidental change = 68% conserved
older children did better
-piagets method didnt show what children can do
this study does show that there are age related changes
mcgarrigle and donaldson
evaluation
=weakness
-the primary age children all come form one school
-the reason that the primary children did better than the nursery ones might be becasue od the educational background
-mihgt not be reasonable to compare the two groups of children
mcgarrigle and donaldson
evaluation
=weakness
-the change was nit noticed
-the children may have been more likley to say that both rows were the same because they were the same because they were distracted by the teddy and didnt realise the change
-the distraction meant that the children went looking at it , didnt mean that they wernt conserving.
