Approaches Flashcards
key features of science
-empirical methods and replication ( getting the same results when repeating)
- the role of peer review in validating research
-hypothesis testing (accept or refute statement)
-use of objective methods
Willhelm Wundt
-first man to be considered a “psychologist”
-believed all things including the human minds can be studied scientifically
-opened the first psychology lab in Germany
- studied introspection
introspection
‘looking into’- how things made people feel
The Behaviourist Approach assumptions
-ALL behaviour is learned form the environment
-nothing is innate and we are born as a blank slate {tabula rasa}- life experiences teach us
- rejects introspection, as it is observable behaviour
classical conditioning
learning through association
-pairing two stimuli together to create a connection
Pavlov’s Experiment
dogs with food and salivation
(details on next card)
before conditioning in Pavlov’s Experiment
food (unconditioned stimulus) shown to dog and the dog salivates (unconditioned response)
during conditioning in Pavlov’s Experiment
sound of a bell( neutral stimulus) and food (unconditioned stimulus) at the same time
after conditioning in Pavlov’s Experiment
the bell WITHOUT food (conditioned stimulus) makes the dog salivate (conditioned response)
problems with Pavlov’s Experiment
-done on dogs so cannot be generalised to humans- they are not as cognitively developed as humans and don’t understand things the way we do
Little Albert Experiment- before conditioning
the white rat (neutral stimulus) is shown to Albert and he has no response
then a loud noise is made (unconditioned stimulus) and the child is fearful (unconditioned response)
Little Albert Experiment- after conditioning
white rat (without the loud noise) creates fear from child (conditioned response)
operant conditioning
learning through rewards and consequences
positive reinforcement
addition of something strengthens behaviour- encouraging someone to do it again
negative reinforcement
removal of unpleasant stimulus strengthens
e.g your mum nags you (unpleasant stimulus) about your messy room, by tidying your room you are removing the negative stimulus as they won’t nag you anymore
punishment
unpleasant consequence of behaviour
Skinner’s Box Experiment- positive reinforcement
done with rats in a box- when the rat pressed a leaver it presented food, the rat repeated this once it realised it got food, the rat is being rewarded with food
Skinner’s Box Experiment- negative reinforcement
the rats were given an electric shock and it was taken away when a certain behaviour was performed- the rat is avoiding an unpleasant stimulus by acting a certain way.
AO3- behaviourist approach is scientific
strength ✅ the behaviourist approach gathers objective data(not an opinion) through lab experiments (controlled)
-this also means that we can repeat the experiments and check for reliability
HOWEVER ❌ lacks ecological validity as it does not reflect real life, limits behaviourist approach from being generalised
AO3- behaviourist approach has real life applications (operant conditioning)
strength ✅ operant conditioning- token economy- tokens/awards can be given out at school and prisons awarding for good behaviour (positive reinforcement) this means people will repeat the behaviour to be rewarded again. Detentions and punishments are also given out at school (negative reinforcement)
AO3- behaviourist approach has real life applications (classical conditioning)
strength ✅ phobias can be unlearned through counter conditioning
AO3- behaviourist approach relies on animal studies
weakness ❌ animal results cannot be generalised to humans as we have different cognitive ability, levels of awareness, lack emotion and brain development compared to animals , so it cannot be said that we would behave the same way to the animals when in these conditions, results are less valid
AO3- behaviourist approach experiments are not ethical
weakness ❌ the animals may now associate the two stimuli for the rest of their lives
HOWEVER, it is more ethical to do on animals than on humans, as they are easier to breed, and it can be argued they are not developed enough to remember/associate
AO3- behaviourist approach ignores thought processes
weakness ❌ the approach only looks at what can be observed and ignores internal mental processes- disadvantage as we know we have thought processes so by ignoring them, it can be seen as unreliable
Biological Approach Assumptions
-all behaviour is strongly influenced by our genetic makeup and inheritance- behaviour is not learned
-behaviour is within you, innate
-everything psychological was once biological
genetic basis of behaviour
behaviour geneticists study whether behavioural characteristics, such as mental disorder and personality are inherited the same way as characteristics such as eye colour- twin studies are used
twin studies
-used to see if characteristics are genetic identical(monozygotic) have higher concordance rates than non-identical (dizygotic) for music ability, love for certain things - suggests genetic basis because MZ share 100% of the same genes
genotype
actual genetic makeup
phenotype
how the genes are expressed through physical, behavioural and psychological characteristics
expression of genotype
influenced by environmental factors, e.g identical twins still look different due to one maybe exercising more or one has dyed their hair
evolution of behaviour (Darwin)
all living things have evolved over time through process of natural selection
- the weaker genes ‘die out’ and adaptive ones survive
genetics
study of genetic makeup of organisms and how genes influence physical and behavioural characteristics
hereditary
traits and behavioural tendencies inherited from ones parents
concordance rates
the higher= more likely a genetic trait
family studies
never 100% as none have the same genetics but likely shared environment
adoption studies
-can split MZ twins and raise them in different environments, and if they behave the same, you can assume that it is innate and not learned form environment
AO3- biological approach uses scientific methods
strength ✅ MRI’s able to accurately measure biological processes, not open to bias/opinion and there is evidence to support (twin studies)
AO3- biological approach can be applied in real life
strength ✅ understanding of biochemical processes lead to development of psychoactive drugs to treat mental illnesses- people who suffer can be helped and live a normal life
AO3- biological approach has a deterministic view of behaviour
limitation❌- sees human behaviour as internal and controlled by biological causes- implications when people are in prison as they could use the excuse that they had no control over themselves and not responsible
AO3- biological approach- difficult to separate nature and nurture
limitation ❌twins and families tend to be brought ups in the same environment as well as similar/same genetic material- so it cannot be determined whether the behaviour is from the environment or internal- also unethical to separate twins at birth just for science- has to be accidental- which is rare
social learning theory assumptions
much of our behaviour is learned from experience- through OBSERVATION and IMITATION of others- indirectly and directly through classical and operant conditioning
-NOT INNATE- learned
identification
attaching oneself to a model because they have the same qualities you wish to process
imitation
copying a behaviour
model
any person who shows examples of behaviour
