Development Flashcards
What is the brain stem?
Highly developed at birth.
Connects brain to the spinal cord. Carries motor and sensory nerves to the brain from the body.
Controls autonomic functions, e.g. heartbeat, breathing, etc.
What is the cerebellum?
Matures late in development.
Located near the top of the spinal cord.
Main role is the coordination of movement and sensory information (sensorimotor).
What is the thalamus?
Located deep inside the brain in each hemisphere.
Acts as a hub of information receiving signals from other areas of the brain and sending these signals on.
What is the context/cerebral cortex?
Cortex is thin and covers the brain. It is highly folded.
Divided in two hemispheres and several regions: frontal cortex (thinking), visual and auditory cortex (sight and hearing), motor cortex (movement).
At birth the cortex is basic and develops through life.
What are the roles of nature and nature?
Nature is the influence of things you have inherited.
Nurture is the influence of your environment on your development.
How does smoking affect pregnancy?
Mothers who smoke during pregnancy can have smaller babies with smaller brains as nicotine slows brain growth.
How does infection affect pregnancy?
Mothers who get German measles during pregnancy can have babies with brain damage, such as hearing loss.
How do voices affect pregnancy?
Babies learn to recognise their mother’s voice and even respond to book passages that had been read to them in the womb (DeCasper and Spence).
What is the interaction between nature and nurture?
Your brain is formed due to nature but even in the womb your environment influences the development of the brain.
It is nature and nurture rather than just one or the other.
What is piaget’s cognitive development theory?
Cognitive refers to mental processes, particularly thinking.
Cognitive development is about the change in the way we think across time.
Piaget believed that children think differently from adults.
What are schema’s?
As children develop they create mental representations of the world which are stored in the form of schemas.
A schema is a mental structure containing knowledge.
They become more numerous and more complex through assimilation and accommodation.
What is assimilation?
Assimilation occurs when we understand a new experience through adding new information to an existing schema.
A car schema is changed when a two-seated sports car is seen for the first time.
What is accommodation?
Accommodation occurs when we acquire new information that changes our understanding so we need to form new schema(s).
When a child sees a tractor they change their car schema or form a new tractor schema.
What are the evaluation point’s of Piaget’s theory?
A strength of Piaget’s theory is that it has led many studies to be carried out.
These have helped test the claims of his theory.
This is an important part of any theory – if we can’t test it we don’t know if it is right or wrong.
A strength of Piaget’s theory is that it has helped change classroom teaching for the better.
It has led to teachers carrying out more activity-based learning.
This has helped children learn in a more effective way.
A weakness of Piaget’s theory is that research was carried out on middle-class Swiss children.
These children were from families where academic studies were more important than making things.
Therefore his theory may not be universal.
What is conservation?
The ability to realise that quantity remains the same even when the appearance changes.
Piaget showed that younger children can’t conserve with number or volume. This was challenged by McGarrigle and Donaldson’s ‘naughty teddy study’.
What was the aim of McGarrigle and Donaldson’s naughty teddy study?
McGarrigle and Donaldson wanted to see if younger children could conserve if there wasn’t a deliberate change in a row of counters.
What was the aim of McGarrigle and Donaldson’s naughty teddy study?
4–6-year-olds were shown a naughty teddy and two rows of four counters.
Teddy jumped out of his box and messed up one of the rows (making it look smaller).
Each child was asked before and after the teddy jumped out ‘Is there more here or more here or are they both the same number?’
What were the results of McGarrigle Donaldson’s naughty teddy study?
41% of the children knew the rows had the same number if the counters were changed intentionally (i.e. they could conserve).
68% could conserve if the change was accidental.
Older children gave more correct answers than younger children.
What was the conclusion of McGarrigle and Donaldson’s naughty teddy study?
This shows that Piaget’s method of testing conservation doesn’t show what children can do.
Children aged 4–6 could conserve number when the change was accidental. Piaget believed they could not do this until 7 years.
It does support Piaget’s idea of age-related changes but not the age that conservation develops.
What are the evaluation of McGarrigle and Donaldson’s naughty teddy study?
One weakness is that the primary age children all came from one school.
The primary children might have done better than the nursery children due to differences in educational background.
Therefore, differences between the two groups of children might be due to other factors.
A weakness is that children may not have noticed the change in the accidental condition.
Moore and Frye showed that, if the teddy did actually take a counter away, they still said the rows were the same.
This means it wasn’t that the children weren’t conserving, they were just distracted.
A strength of this study is that it challenges Piaget’s theory.
McGarrigle and Donaldson’s study implies that Piaget’s original work confused young children.
Therefore this study helped refine this type of child development research
What was Piaget’s study of egocentrism?
Egocentrism means to see the world only from one’s own point of view.
Piaget tested children with his three mountains task and concluded that they are egocentric until about 7 years of age.
What was the aim Hughes policeman doll study?
Hughes aimed to create a test of egocentrism that would be more understandable to children younger than 7 years.
What is the method of Hughes policeman doll study?
Children aged 3½ to 5 years old were shown a model with two intersecting walls.
The child was asked to hide one boy doll from one policeman doll to ensure they understood the task.
The child’s egocentrism was then tested by asking the child to hide the boy doll from two policemen.
