development Flashcards
paper 1 section C
the brain stem
- connects to spinal cord
- carries motor and sensory neurons to and from the brain via the spinal cord
- controls automatic such as breathing, heart rate, sleeping as apart of the auntonomic system
- most highly developed at birth as its key to survival
cerebellum
- means little brain
- coordination of movement
- some input in language and emotions
- one of the last to mature
thalamus
- located deep inside the brain
- acts as a hub of information
- receives signals from other areas and also passes them on
cortex
- bumpy structure surrounding brain giving it a groovy shape
- thinking and processing
- motor and sensory areas of the cortex are active in the womb but other areas continue growing in life
how does smoking affect brain development
it can affect the size of the brain as well as its growth if a pregnant woman smokes
how does infection affect development
illnesses such as rubella can cause brain damage such as hearing loss if contracted in the first 20 weeks of pregnancy
how does voices affect brain development
babies recognise their mothers voices immediately after birth showing your brain adapts during development in response to external stimuli
piagets theory of cognitive development
- young children are not mature enough to think logically
- brain develops in stages
- we store knowledge in schemas for all information we come across
- assimilation= adding to an existing schema
- accommodation= changing a schema or creating a new one
evaluation of piagets theory
+ research - piagets theory led to many to follow his footsteps and conduct their own theories although not all of them supported him. high internal
+ real world application- his theories were applied to classrooms to make them more productive rather than copying off the board. high external
McGarrigle and Donaldson’s naughty teddy study
method: 80 primary and nursery students from edinburgh were introduced to the naughty teddy. they were then shown 2 rows of 4 red counters and white counters, the teddy then jumped out of its box and messed up the counters making one row look smaller, the children were asked which row had more counters or if they were the same
results: 41% said there was the same amount if the change was deliberate and 68% said the same amount if the change was accidental
evaluation of the naughty teddy study
- the sample- all the children came from the same school meaning its not generalisable to the population. low external
- the change wasn’t noticed- the study was conducted again by another researcher but this time the teddy took a counter and the child still said they were the same amounts, meaning they might have been distracted by the teddy and didn’t notice a change. low internal
Hughes’ policeman doll study
method: tested children ages 3.5 to 5. they were shown a structure of 2 intersecting walls, with a policeman sat left of the child also looking at the structure. a boy doll was then placed in different sections of the structure and the child was asked if the policeman could see it, the policeman was then moved to the right of the child as asked to hide the boy themselves. if the child made mistakes, they were corrected and asked to try again. if the study went well there was 2 policemen placed and the child asked to repeat
results: 90% of children were able to hide the boy from 2 policemen
evaluation of the policemen doll study
+ realistic- children have more experience of hiding from games of hide and seek than the three mountains task piaget performed. high internal
+ challenges piaget- the tasks piaget based his research off of may have confused children, and helped to rethink the ages he stated in his study. high internal
the sensorimotor stage
- ages 0 to 2
- learn from their senses and performing tasks
- children do not have object permanence
the pre operational stage
- 2 to 7
- they are mobile and can use language but not logically
- they do not have egocentrism
