development Flashcards
autonomic functions
involuntary bodily functions such as breathing and heart rate
brain stem
the part of the brain that controls basic functions such as breathing and heart rate
cerebellum
a small wrinkled structure at the back of the brain which coordinates motor movement, dexterity, and balance
cognition
the mental processes involved in gaining knowledge; these include thinking, planning and problem solving
cortex
the outer layer of the brain where higher cognitive functions take place e.g speech
neuron
a specialised nerve cell which generates and transmits an electrical impulse
sensory processing
the brain receives messages from the senses and turns them into appropriate motor and behavioural responses
synapse
the small gap between the dendrite of one neuron and the receptor site of the next one, which allows signals to pass between them
thalamus
the part of the brain that passes info from the sense organs to the cortex
early brain development
- begins during third week of pregnancy, multiplying cells form a structure called the neural plate which forms a tube-shaped structure called a neural tube.
- fourth week: neural tube divides into spinal cord, forebrain, midbrain, and hindbrain.
- sixth week: forebrain divides into two areas (pink and yellow). pink forms cortex, yellow develops into thalamus. neurons and synapses develop in the spinal cord (allows fetus to move around and react)
- fifteenth week: cerebellum formed from hindbrain
- cortex develops in last 3 months
occipital lobe
processes visual info
temporal lobe
involved with hearing
parietal lobe
processes info related to touch on the skin like heat, cold, and pain
frontal lobe
associated with cognitive activities such as thinking, planning, and problem solving
nature
the idea that our characteristics and behavior are inherited
nurture
the idea that our characteristics and behavior are influenced by our environment
twin studies
identical twins have the same genes, studies show they have similar IQ implying that nature has a major role in intelligence. Study showed that nature plays more of a role in personality than nurture
newborn babies
nature is responsible for babies being able to recognize faces. nurture is responsible for language development
animal studies
rat study supports that nurture is very important for early brain development.
schema
a cognitive model of people, objects, or situations; based on previous information and experiences which helps us to perceive, organise, and understand new information
accomodation
- mental blocks of knowledge develop through experience
- changing a schema, or developing a new schema to cope with a new situation
