development Flashcards
brain stem:
-connects brain to the spinal cord.
- carries messages via the spinal cord.
- function: controls autonomic functions in the body.
-highly developed at birth.
cerebellum:
-matures late.
-near top of spinal cord.
-function: coordinates sensory info and motor activity as well as movement (balance).
thalamus:
-deep inside the brain in each hemisphere.
-function: information hub - receives and sends signals around the brain.
cortex:
-divided in 2 hemispheres.
-outer covering of brain, very thin and folded.
-function: thinking and processing.
-frontal, visual, auditory, motor areas in each hemisphere.
roles of nature and nurture:
nature: inherited.
nurture: environmental influences on development.
smoking during pregnancy:
affects the size of the brain and body because nicotine slows down brain growth.
infection during pregnancy:
in the womb, german measles can cause brain damage (more specifically hearing loss).
voices during pregnancy:
- babies learn to recognise mother’s voices.
- brain is changing before you are born in response to external stimuli.
the interaction between nature and nurture:
- both aspects at the same time.
- brain forms due to nature (product of genes) but the environment has a major influence even in the womb.
outline Piaget’s theory of cognitive development.
Theory:
-changes in thinking (cognition) over time (as we get older).
-children think differently from adults.
Stages:
-young children aren’t able to think logically about the world (brains aren’t mature enough).
-as the child gets older their brain develops and different kinds of thinking such as being able to think in abstract ways.
Schemas:
-the world is represented in the mind where knowledge is stored.
-as the child develops the construct more and more detailed and complex schemas.
-number of schemas increase as we grow older through assimilation and accommodation.
Assimilation:
when we understand a new experience and add that new information to an existing schema.
Accommodation:
receiving new information that changes our understanding so a new schema is formed.
strength of Piaget’s theory of cognitive development:
*real world application
P- has real world application.
E- the theory has helped change classroom teaching so it’s now more activity based.
L- demonstrates it’s positive value (usefulness).
strength of Piaget’s theory of cognitive development:
*a lot of research
P- enormous amount of research (evidence) to test his ideas.
E- many studies have been conducted to test Piaget’s theory.
L- we can be more certain about what aspects of his theory need refining and which has helped improve our understanding of how children’s thinking develops.
conservation:
although appearance changes, quantity stays the same.
Piaget and conservation.
- Piaget showed that younger children can’t conserve quantities.
- showed children 2 identical rows of 6 counters each, equally spaced; the children correctly reasoned that each row had the same number.
- however when the counters in one of the rows were pushed together, the young children struggled to converse and usually said there were less counters.
- this is challenged by the naughty teddy study.
- they wondered if Piaget’s results were due to the fact that the children saw the counters being changed and may have thought this meant that there was an actually deliberate change in the number of counters.
outline the naughty teddy study.
*McGarrigle and Donaldson
A: aimed to see whether the child’s reaction would be different if there was no deliberate change in the row of counters.
M: 80 children aged 4/6 years old
-introduced to “naughty teddy” who could spoil their game.
-shown 2 rows of equal counters.
-teddy jumps out of box and pushes the counters in one row about, transforming display by making one row look smaller.
-child was then asked if the rows had the same amount of counters.
R: -deliberate change: 41% gave the correct answer (same number in each row).
-accidental change: 68% gave the correct answer.
-older children did better than younger children.
C: -Piaget’s method doesn’t show what children can do (nursery kids conserved quantity).
-older children did better than younger ones which supports Piaget’s idea that the way children think changes as they grow older.
weakness of the naughty teddy study:
*sample
P- primary children all came from one school.
E- primary kids may have done better than the nursery kids due to their educational backgrounds, may have coped better due to their better developed language/better educated families.
L- challenges validity of conclusions as other factors can explain the difference.
