classic study: Watson and Rayner (1920) conditioned emotional reactions Flashcards
(18 cards)
background
- test if classical conditioning works on humans
- condition little albert to fear something he wasn’t scared of (a white rat)
- use reflex actions and new stimuli to create an emotional response
- demonstrate humans can develop fears through association
- single case exp
what was the aim of watson and rayner’s 1920 study?
- investigate if an emotional response eg fear could be conditioned
- test if fear could be learnt through association
why did watson and rayner choose albert b as the participant?
- albert was healthy and well-developed
- he was relatively fearless and unemotional
- they believed they could do him relatively little harm during the experiment
when did watson and rayner test albert for fear reactions?
- when albert was about 9 months old
what was albert’s reaction to the stimuli introduced in the study?
- introduced to a white rat, rabbit, cotton wool, and other stimuli
- filmed his reactions
- he showed no fear and was simply interested in the objects
what happened when watson and rayner made a loud noise in the study?
- banged a hammer against a suspended steel bar to create a loud noise
- this caused albert to show a fear response
- albert trembled and cried
- it was the first time he had cried in the laboratory
what happened when albert was presented with the white rat at 11 months old?
- albert reached for the rat
- as his hand touched it, the hammer struck the steel bar making a loud noise
- albert jumped and fell forward but did not cry
- when he tried to touch the rat again, the loud noise occurred again
- this time, albert jumped violently, fell forward, and began to whimper
what happened after the rat and noise were paired together a few times?
- the rat and noise were paired together multiple times
- albert showed increasing distress each time
what happened when the rat was presented alone after several pairings?
- the rat was presented alone (without the loud noise)
- albert started to cry immediately, turned, and crawled away
what were the results of the study after one week and what did they demonstrate?
-
little albert acquired a fear of rats as a learnt emotional response
- the rat and loud noise created an association
- the rat became a conditioned stimulus, producing fear as a conditioned response
- the fear response generalised to similar objects like a Santa Claus mask, fur coat, and cotton wool
- at age 1 year 21 days, albert was still afraid of the rat, even without the loud noise
- although the response was weaker, it was still present and thought to last a lifetime
- albert was removed from the study, so there was no way to see if the response extinguished (died at age 6)
what did watson and rayner conclude from their study?
- it is possible to classically condition the emotional response of fear
- the conditioned response can generalise to other similar objects
gen - weakness
- it is a single case exp, so the findings may be limited to albert
- replications of the experiment failed to reproduce the findings
reliability - strength
- the study was carefully documented with witnesses recording the data
- there were strict controls in place
- albert’s reactions were carefully recorded, and the setting was controlled
- the independent and dependent variables were clear
- the experiment could be replicated and tested for reliability
application (cc)
- pavlov showed classical conditioning in dogs
- it might have been difficult to generalise pavlov’s results to humans
- watson and rayner’s study provides evidence that classical conditioning occurs in humans
- it shows that humans can learn an emotional response through classical conditioning
application (phobia)
- it gives insight into how humans might acquire a phobia
- shows phobias can develop through a learnt association (via classical conditioning)
validity - strength
- the experiment has good face validity
- it appears that watson and rayner successfully conditioned albert to become fearful of the rat by pairing it with the loud noise
validity - weakness
- the study may not be valid due to the artificial setting (laboratory)
- the noise from a hammer on a steel bar could be realistic, but the setting was not natural
- albert was in a laboratory situation, which may have made him initially fearful
ethics - weakness
- the study is not ethical
- although the researchers ensured albert was not easily frightened, there is clear evidence he was distressed
- albert was not sufficiently protected from the distress caused by the experiment
