component 1 Flashcards
localisation of brain function (biological)
- human behaviour is determined by a physiological cause, being g the activity on individual parts of the brain
- 2 hemispheres and 4 lobes
- Phineas gage, metal rod penetrated through frontal lobe showed aggression
neurotransmitters (biological)
- suggests that behaviour is caused by electrical and chemical communications in the brain
- e.g. raised levels of dopamine have been linked to schizophrenia, and low levels of serotonin have been linked to depression
*neurons pass neurotransmitters through the synapse and are released from presynaptic vesicles
evolutionary influences (biological)
- Charles Darwins theory of natural selection
- males subconscious desire for fertility in females
- e.g ostrich may dance to attract a mate
humans are born as a blank slate (behaviourist)
- idea that humans are born as “tabula rasa”, and that behaviour is environmentally determined and humans are born with hunger, pain and crying
- dies developed by Watson, he stated that he could turn a “dozen infants” into “any type of specialist”
- bandura tested with bobo doll experiment
behaviour is learned through conditioning (behaviourist)
- classical conditioning suggests that behaviour is learnt through association. pavlov (1902) tested with dogs teaching them to salivate with bell and treats
- operant conditioning is behaviour learnt through reinforcement. skinner (1936) tested with rats
- Gill proves operant conditioning as effective as he claims that children who get pocket money complete 20% more household chores
- Watson and Rayners little Albert study supports
humans and animals learn in similar ways (behaviourist)
- suggest that humans and animals behave in similar ways due too shared traits such as fear
- joint stimulation was used with pavlovs dogs and little Albert
- operant conditioning has been proved effective in schools and prisons
tripartite personality (psychodynamic)
id ego and superego
id is primitive, requires instant gratification and is pleasure seeking principle. ego is mediator and superego is concerned Sith moral values
each part represents a part of the brain. id represents limbic system and ego represents prefrontal Cortex
unconscious mind (psychodynamic)
conscious preconscious and unconscious
preconscious are things such as memories or knowledge that could be easily retrieved
anxiety acts as a signal to the ego that there is dysfunction somewhere
ego defence mechanisms such as repression help ease these feelings
childhood experiences (psychodynamic)
psychosexual stages refers to a stage and age theory that all children go through at roughly the same time influenced by the location of libido
e.g. oral, anal, phallic, latency and genital
being stuck at a stage, eg oral, leads to adult fixations such as nail biting
internal mental processes (cognitive)
cognitive psychologists see humans as information processors
memory, perception, attention, thinking and language
eg. to recognise a dog, you need to pay attention, perceive its features, then search through our memory store to see if anything matches and we use language to name it
computer analogy (cognitive)
both humans and computers are the same in the way that they process information
mental processes used: input, processing and recall
process stage involves memory, perception and attention
multistore model of memory made by Atkinson and shiffin (1968) shows how long term and short term memory are stores as “hardware”
schemas (cognitive)
pockets of information built from experience
built up via social interactions, which can potentially distort the information as humans may select and interpret environmental stimuli using irrelevant schemas
this may explain inaccuracies in EWT
e.g schema for burglar
bowlby methodology
opportunity sample and matches pairs design
quasi difference experiment
iv: whether they had stolen or not, DV: whether they were an “affectionless psychopath”
31 boys, 13 girls
control experiment used of children who went to the same child guidance clinic but had not stolen.
weaknesses of bowlbys methodology
unrepresentative as not all children are emotionally disturbed
violent homes could be a confounding variable
strengths of bowlbys methodology
used a control group so more reliable results and higher ecological validity
bowlbys procedure
- mental test given to children to test intelligence and how well they emotionally reacted to it
*preliminary psychiatric history was gathered from the social worker
- psychiatrist interviewed mother
*then bowl by examined the mother and child together
*psychotherapy for at least 6 months after
weakness of bowlbys procedure
could be social desirability bias in mother’s interview
strength of bowlbys procedure
strong qualitative data gained from multiple sources
bowlbys findings
- 6 categories of children: affectionless, hyperthermic, normal, depressed, circular and schizoid
- majority were affectionless, 14 out of 44
- out of those 14, 12 of them had prolonged separation from mother
*40% of thieves had prolonged separation from mothers, compared to 5% of control group
main components of systematic desensitisation
*phobia is learnt response
- sd uses reciprocal inhibition in order to counter condition the patient
- developed by Wolpe (1958)
- relaxation techniques and desensitisation hierarchy
*in vivo
*in vitro
strengths of systematic desensitisation
Capafons et al (1988) found that after 12-28 weeks of SD, clients with a fear of flying showed less fear in a flight simulator
