DEVELOPMENT Flashcards
what are the four key stages of brain development
pre - natal, childhood, adolescence and adulthood
what is the nervous system
network of nerve cells and fibres that transmit impulses between body parts
draw and label the main parts of a neuron
include - cell body, nucleus, dendrite, myline sheath, axon
what does the dendrite do
collects chemical messages and transforms it into electrical impulses
what does the axon do
carries electrical impulses through the neuron
what does the myelin sheath do
protects the axon preventing loss of electrical impulses
name and label the parts of the brain
frontal lobe, parental lobe, temporal lobe, occipital, hippocampus
what is the purpose of the frontal lobe
problem solving, movement, speaking
what is the purpose of the parental lobe
reading, senses
what is the purpose of the temporal lobe
listening
what is the purpose of the occipital lobe
vision, colour perception
how does the stage of pre natal help brain development
- the neural tube is developed into the spinal cord and brain
- cerebral cortex is then formed - needed for thinking and acting
- then divided into four sections
- neurons begin to develop
- simple synapses form allowing neurons to communicate
how does the stage of childhood help brain development
- new synapses form to allow baby to see in 3d and colour
- prefrontal cortex is at peak allowing children to use past experiences to understand present
- neural connections are then pruned
- frontal lobe = a lot of development
how does the stage of adolescence help brain development
- brain remodelling
- grey matter reaches maximum density
and then prunes away - limbic system first to mature
- prefrontal cortex still developing meaning relying on limbic system to take over
- explains risk taking behaviour
- frontal lobe = mature at 16
how does the stage of adulthood help brain development
- prefrontal cortex finally matures (25)
- helps people make rational decisions and focus on long term consequences
- brain volume decreases
- later adulthood development of neurodegenerative diseases
these are progressive and get worse over time and are believed to result in the death of neurons in the brain.
what are IQ tests
tests designed to measure intelligence
who created IQ tests
Alfread Binnet
why did he create IQ tests
French government wanted to help children in school
what do IQ tests measure
memory skills, attention, problem solving skills
how did IQ tests create a controlling society and why
psychologists set IQ tests to determine if people could enter the county, get jobs or fight in war - people may not speak native language so unfair
who created the theory of cognitive development
Piaget
what are the four stages of cognitive development and ages
sensory motor - 0-2
pre operational - 2-7
concreate operational - 7-11
formal operational - 11+
what is a schema
mental structures of our world enabling to understand the present
what is assimilation
new information that children encounter are merged into EXISTING schemas
