true or false “mental processes are studied directly by making inferences”
false
1 reason why schema is useful/not useful
useful: prevents us from being overstimulated by our environment/having to process too much information
not useful: may cause biased recall/make us see what we expect
displacement
focus of strong emotiom is expressed on a neutral/alternative person/object
denial
when someone refuses to accept reality
repression
when someone buries a memory or thought deep into their subconscious/mind and avoid it
compare behaviourist and biological approach
- nature/nurture
- scientific methods
- both reductionist
- applications to abnormal treatment
- both determinist
ANS
governs vital functons
SNS
Governs muscle movement and receives information from sensory receptors
sympathetic nervous system
increases heart rate, activates the “fight or flight” response
parasympathetic nervous system
decreases heart rate, activates “rest and digest” response
how many directions can information travel at a synapse
1
why can neurons only transmit information in one direction at a synapse (3)
- the signal can’t go backward due to necessary structures which are only in the presynaptic terminal
- neurotransmitters are released from the presynaptic membrane
- receptors are only found on the postsynaptic membrane
Summarise the ‘fight or flight’ response (4)
- Stressor activates the pituitary
- Activates sympathetic nervous system
- Adrenaline (stress hormone) released from adrenal medulla into the bloodstream, causing changes around body
- Once threat has passed the parasympathetic nervous system ‘rest and digest’ response is activated
how are signals in/between neurons transmitted
signals are transmitted electrically within a neuron but transmitted chemically across the synapse between neurons
chemical transmission
where neurons communicate with each other using neurotransmitters
neurotransmitters
chemical messengers
explain the 5 stages of chemical transmission
- electrical impulse travels down the axon of the presynaptic neuron
- triggers release of neurotransmitters in tiny sacs called synaptic vesicles
- neurotransmitters are then released into the synaptic cleft
- neurotransmitters bind receptors on the postsynaptic neuron
- binding generates a response in the postsynaptic neuron (exhiting or inhibiting it)
exogenous zeitgebers
external changes in the environment (eg. light) that help regulate biological cycles (eg. the sleep/wake cycle)
why does light have such a powerful effect on sleep
light is one of the most powerful exogenous zeitgebers because it influences the production of melatonin which is one of the key hormones that helps control sleep
discuss what julia could do to encourage her baby to sleep more at night
- establish a night routine
- dim the lights
- expose the baby to natural light during the day
julia and her baby evaluations (8 marker)
(s) studies show light has an impact in regulating sleep. Gooley et al. (2003) found light exposure during the day can help promote babies to sleep at might
(L) young babies may have not developed their own internal biological clocks also known as exogenous pacemakers. meaning the child may be less responsive to external cues so julia has to be patient
endogenous pacemaker
internal biological clocks (eg. SCN provides information from the eyes about light)
what do external cues effect on endogenous pacemakers
may influence/entrain biological rhythms (endogenous pacemakers)
does the production or suppression of melatonin influence people’s sleep/wake cycle
suppression
