Development Flashcards
Describe the cortex
Outer covering of brain where mental processing takes place. It’s used for thinking/cognition sensory processing and motor processing.
Describe the cerebellum
At base of spinal chord. Plays important role in coordination of movement like balance
Describe the thalamus
Located deep in brain and receives and sends signals
Describe the brain stem
Part of brain that connects to spinal chord and is used for breathing and other basic functions.
What is the difference between nature and nurture
Nature is the genetic influences and characteristics from our ancestors and nurture is the other influences like how you were raised and your environment
Outline Piaget theory of cognitive development
He suggests that the way children think change as they get older
What is assimilation and accommodation
Assimilation- when we add new information to an existing schema
Accommodation - when we learn new information that does not fit with our existing schemas so therefor a new schema is made.
What is conservation
Knowing the amount of something stays the same envelope though it’s appearance may change
What is egocentrism
Not being able to see things from another point of view
What is object permanence
Knowing that an object still exists even if it is out of sight.
What are the for stages of development and explain them
Sensorimotor - 0-2 years child develops object permanence
Pre-operational - 2-7 years children are egocentric
Concrete operational - 7-11 years children begin to conserve
Formal operation - children can now solve problems in systematic ways and can create and imagine situations that have not yet happened
Evaluates Piaget stages of cognitive development
Weakness
Tested in children
Overestimated what they can achieve and some may not even achieve this stage
Describe and evaluate huges policeman doll study
He wanted to see if children were able to see things from another pov earlier than Piaget suggested
He got children from Edinburgh and showed them a model with two intercepting crosses and placed a policeman doll in there and asked the children to bide the doll form the police this was then repeated to see if the child understood so the police man was placed in a different sport and they were told to reside the doll.this was all a test and for the real experiment they were told to hide the doll from 2police dolls so neither police men could see. Results show that 90% of children were able to hide the doll but according to Piaget they shouldn’t be able to do so
This shows that Piaget underestimated younger kids as they can view from different perspectives
Weakness
Only tested on kids from Edinburgh
Researcher may have subconsciously hinted correct answer to children= invalid
Describe and evaluate the naughty teddy study
They wanted to see wether the children saw the counters being changed and maybe assumed if it was a deliberate change
There were 80 children from Edinburgh in this study 40 were in nursery 4y 10 m and 40 in primary 5y 10m who were introduced to naughty teddy who would spoil their game . They were show 2 rows of counters and the teddy made one look longer when he jumped out in a chaotic matter. The children were asked before and after the transformation if th the rows were different of the same.
41% of gave correct answers when it was deliberately changed
68% gave correct answer when it was accidentally changed by teddy
Therefore showing that Piaget underestimated what children can do but there was a difference in the ages showing that Piaget ideas of us changing as we grow or right
Weakness
All kids from Edinburgh
30% of children failed and when replicated results were not as high as their findings
What is a fixed mindset
Belief that achievement are due to abilities you are born with and these no point in trying if u lack the ability
