QUESTIONS WITH VERIFIED ANSWERS
GRADED A+
⩥ psychology. Answer: the science of human behaviour and the
underlying mental processes
it includes all behaviour
the process in the body, brain and nervous system that cause behaviour
-> always in a social environment embedded in a cultural environment
⩥ science. Answer: using the scientific method to obtain knowledge,
through measurement to knowledge
⩥ sensation. Answer: a feature experienced by the brain, triggering the
activation of receptors
⩥ perception. Answer: integrated sensations and existing knowledge
experiences to make a meaningful interpretation
,⩥ what is the role of perception/ how does it work. Answer: without
perception, there is no behaviour perception is the psychological process
of selecting, organizing and interpreting stimuli from the environment
stimulus activates receptors
receptors activate the nervous system
sends information to the brain
results in sensations
nerve cells always involved
a neuron sends information through axon
end points of axon connect to another neuron to transfer information
in the connection points information is transmitted through the use of
neurotransmitters
⩥ stimulus. Answer: a signal to which an organism responds
⩥ neurons. Answer: nerve cell; a cell that can send and receive electrical
signals
⩥ neurotransmitters. Answer: a molecule that binds to a receiving cell,
causing an increase or decrease of electrical potential of the cell.
it enhances or inhibits the transmission of a signal to the next neuron
,they allow for ions to pass into the cell, changing its electrical potential
to facilitate/enhance or inhibit signal transmission
⩥ signal transmission. Answer: axon terminals release of
neurotransmitter
therefore neurotransmitters are involved
⩥ receptors (the beginning of sensations). Answer: parts of the cell
membrane that receive the neurotransmitter and initiate or prevent a new
electric signal
⩥ the brain/ cerebral cortex (the end of sensations). Answer: activity in
the nervous system, transformed and prolongated to the brain to make
sense of what we are doing
cerebral cortex is the outer layer of the brain, there are many neurons to
process information
⩥ parts of the cerebral cortex. Answer: frontal lobe, parietal lobe,
occipital lobe, temporal lobe, cerebellum
⩥ transduction. Answer: transition from a stimulus to electrical activity
in the nervous system
, ⩥ what are the senses where transduction occurs in special cells which
then activate neurons. Answer: taste hearing vision
⩥ what are the senses where transduction occurs in the neurons. Answer:
pain smell touch
⩥ hearing. Answer: sound waves or vibrations of air causes waves in the
fluid in the cochlea
⩥ ear anatomy. Answer:
⩥ mechanisms of hearing. Answer: the receptors of the ear for hearing
consist of hair cells, in which the sound activates them by bending them
⩥ cochlear. Answer: pertaining to a snail-shaped structure within the
middle ear
⩥ basilar membrane. Answer: a structure in the inner ear that moves
when vibrations from the ossicles reach the cochlear fluid
when this moves with the travelling wave, it sets the motion the whole
process
- basilar membrane moved
- hairs bent
