Development Flashcards
what is nature
when characteristics and behaviour are inherited from parents
what is nurture
when characteristics and behaviour are influenced by the environment
what is an interactionist approach
both together
is nature and nurture seen as an interactionist approach
yes
what is a schema
a piece of knowledge on a particular subject
what are autonomic functions
they just happen
eg. breathing and blinking
what is assimilation
new information is taken on board and added to a pre existing schema
what is accommodation
taking on board new information and understanding it, may involve creating a new schema or altering existing ones
what is an extraneous variable
factors that can effect results in a study
what happens in the cortex
all thinking and processing goes on in (cognition)
what is the cortex
a thin, outer layer of the brain, it is divided into 2 hemispheres - lots of it because it is very folded
what is the cortex also known as
cerebral cortex
what is the cortex split into?
what are they called?
- lobes
- frontal lobe
- temporal lobe
- parietal lobe
- occipital lobe
when does the cortex start to function
in the womb- the developing baby starts to learn but at birth the cortex is fairly basic and develops throughout our lives
how thick is the cortex
3mm
what happens in the thalamus
it receives messages from the senses and turns them into behaviour motor responses- coordinates motor signals and all sensory information passes through
what is the thalamus also known as
the sensory processing station
where is the thalamus found
a deep chamber in the centre of the brain
what does the thalamus look like
the size and shape of a walnut
how many thalamus’ are there
2- one on the left, one on the right(hemispheres)
what does the cerebellum do
- coordinates movement and balance- receives info from brain and fine tunes it into motor activity
-coordinates sensory information (SENSORIMOTOR), language and emotion
what happens if a person suffers damage to the cerebellum
have difficulty with muscular coordination
what is the cerebellum also known as
little brain
which part of the brain is last to reach maturity
cerebellum
where is the cerebellum located
back of the brain, top of spinal chord
where is the brain stem located
connects spinal chord to the brain
what does the brain stem do
controls basic AUTONOMIC functions
what does the brain stem carry to the brain
motor and sensory nerves to the brain from the rest of the body via the spinal chord
what part of the brain is the most highly developed at birth
brain stem
what happens at six week of pregnancy
the baby’s heart beats regularly and blood pumps through main vessels
how are neurons connected
in a wat that allows them to communicate and process information
what does the axon carry
can carry an electrical signal to other areas of the brain, muscles etc.
when does the brain development start in pregnancy
3rd week
what do the multiplying cells form
a structure called the neural plate which folds over onto itself to form a neural tube
during the 3rd/4th week the neural tube begins to divide into what?
- spinal chord
- midbrain
- hindbrain
- forebrain
when does the cortex form
6th/ 7th week
when does the thalamus form
6th/7th week
what allows the foetus to move around
when neurons and synapses begin to develop in the spinal chord
what are synapses
small gap at the end of a neuron that allows a signal to pass from the neuron to the next
when does the cerebellum form
15th week in the hind brain
when is the brain fully formed in pregnancy
6th month
how big is the brain at birth
25% the size of an adult brain
what are the four stages in paiget’s theory of development in order
- sensorimotor
- pre operational
- concrete operational
- formal operational
what is the age of the sensorimotor stage
0-2 years
what is the age of the pre operational stage
2-7 years
what is the age of the concrete operational stage
7-11 years
what is the age of the formal operational stage
11 plus
what is the main feature of the sensorimotor stage
they develop object permanence
how do children learn about the world
through their senses
what does the sensorimotor stage focus on
basic physical coordination
what is object permanence
knowing an object still exists when they are out of sight
what did Piaget do to investigate object permanence
he gave a child a toy to play with. then when the child was watching he took the toy and hid it under a blanket
he watched to see whether they would look for the toy
what did piaget find when he investigated object permanence?
found children under 8 months did not search but 8 months and above did
- therefore had developed object permanence
what happens in the pre operational stage (2)?
- toddler is mobile but still lack reasoning ability
- focus on one element of a problem and ignore others
what is the main feature of the pre operational stage
children are egocentric
what is egocentrism
not being able to see things from another persons point of view
do children lose or gain object permanence
gain it
do children lose or gain egocentrism
lose it
piaget suggests from 7 onwards they lose it
what did piaget do to investigate egocentrism
the three mountain task-
- he showed a model of three mountains and placed a doll somewhere beside the model . the child was shown pictures from each side view and had to choose the view the doll could see
what did piaget find when he investigated egocentrism
children under 7 chose their own view however older then 7 they were able to choose the right photo
what did piaget conclude from his study on egocentrism
egocentrism decreases with age and children are no longer egocentric after 7
what did piaget believe about the concrete operational
by the time they were 7, they developed the ability to conserve
what happens in the concrete operational stage (2)
- children have much better reasoning ability
- they no longer show centration
what was the main ability in the concrete operatonal stage
children developed conservation
what is conservation
the quantity remains the same even when the appearance changes
do children lose or gain conservation
gain it
how did piaget investigate conservation
he showed children 2 identical rows of counters, then asked the child if there were the same amount of counters in each row.
- when the child agreed, he spread one row out to make it look BIGGER whilst the child watched
he then asked the SAME question
what did piaget find when he investigated conservation
children under 7 said no, children over 7 said yes
what is the main feature in the formal operational
children can solve problems in a systematic way( they can focus on one form of the problem and not be distracted by its content)
what did piaget believe once they can reason formally
they can become capable of scientific reasoning
how did piaget investigate formal reasoning? name?
children were given different lengths of string and weights that could attach to the string
what were the results of piagets pendulum problem
children under the age of 11 would change both at the same time but over 11, they would do it systematically (one at a time)
what was the aim of piagets study for formal reasoning?
investigate what factor affected how fast it swung- by varying the string and weights
what is a weakness of the pendulum problem
too simplistic for such a large age group (11-18)
what are the strengths of piagets theory(3)
- his work inspired others to study cognitive development further, led to educational changes improving standards
- supporting evidence- gains qualitive data for his studies, which was full of valid and realistic evidence
- the evidence supports the view children go through stages
what are the weaknesses of piagets theory
- underestimates what young children are capable of, contrasting evidence of Hughes and mcgarrigle
- used small samples that were unrepresentative of most children, reliability is lower
- piaget assumed childrens thinking changes rapidly in each stage, when it takes place more slowly- overestimated ability of 11 years olds
what is self efficacy
the belief in your own ability to suceed
