Classical Research Flashcards
What was the methodology for Watson and rayner
-controlled observation
-one participant- little Albert
-emotional responses where’s tested at 9 months and observations started at 11months and 3 days
-5 observations
-carried out in a small dark room of a hospital.
How old was Albert when all 5 of the observations took place?
1st- 11months 3days
2nd- 11months 10 days
3rd- 11months 15 days
4th- 11months 20 days
5th- 12 months 21 days
What happened in Alberts first observation?
-11months 3 days
-Watson and Rayner (procedures and findings)
P - a rat was present to Albert and a rod was struck behind his head.
F -when presented with the rat he jumped violently, fell forward and dd not cry
What happened in alberts 2nd observation?
-11 months 10 days
-Watson and rayner (procedures and findings)
P -rat was present to Albert, with the bar being struck repeatedly
F - he cried violently
P - the rat was also presented to Albert alone.
F - he instantly cried and crawled away
What happened in alberts 3rd observation?
-11 months 15 days
-Watson and rayner (procedures and findings)
P- blocks where presented to Albert to act as a control
F- he happily played with the blocks
P- a Santa’s mask was presented to Albert to see if his fear had generalised
F- he did not react to this
What happened in little alberts 4th observation?
-11months 20 days
-Watson and Rayner (procedures and findings)
-P- a rat was presented to Albert alone to see if the fear was still present
-F- he fell to the side but did not cry
-P- a rabbit was presented to Albert to see if his fear had generalised
-F- he reached out to stroke/ touch the animal
What happened in alberts 5th observation?
-12 months 21 days
-Watson and Rayner (procedures and findings)
-p- Albert was present with a fur coat to see if his fear had generalised
-F- he drew back his body and began to whimper
-P- Albert was presented with the rat again
-F- he moved as far away from the rat as possible
-what where the conclusions from Watson and Rayners research?
-yes a fear can be conditioned
-at the age of 9 months little Albert showed no response to stimuli
-after conditioning fear responses where seen
-showing conditioned responses cause fear
What where some methodological issues of Watson and Rayners research ?
-lacks ecological validity, alberts fear was conditioned in a a control environment, can a fear be learnt in a natural environment
-study was only conducted on one participant and can’t be repeated due to ethical issues.
What where some strengths of the methodology used in Watson and Rayners research?
-standardised procedure= high control, therefore Watson and Rayner know fears can be conditioned
What where some ethical issues of Watson and Rayners research?
-emotional harm, Albert was chose as he was a stable baby, however testing a fear on him callus cause him to be unstable.
- emotional Harm- fear was never counted conditioned
-informed consent- Albers mum didn’t know what was really happening, so couldn’t give consent
What are some strengths of ethics in Watson and Rayners research?
+confidentiality, Albert was known as Albert b so no one knew who he was.
-however, a code would of been better
+right to withdraw, Alberts mum did withdraw him from the study.
-however, alberts distressed behaviour showed that he wanted to leave sooner
What was the methodology for rains study?
- experimental group of 41 participants (39 male, 2 female)
-all charged as NGRI for murder
-a control group of 41 was formed by matching each murdered with a control based off: sex, age, mental illness
-both groups where medication free
What where the procedures for Raines research?
-a radio glucose tracker was injected into each participant
-the glucose tracker takes 32 mins to be taken up by the brain, in this time participants did a continuous performance task:
-Participants would see or hear the numbers 1and2 and would have to click a mouse every time they saw or heard the number 1.
-after 32 minutes participants were given a pet scan
-10 horizontal slices of the brain where taken
- experimental groups where compared to controls, on glucose metabolism in in 14 different brain areas (6cortical, 8subcortical).
What where the findings of Raines research?
-lower glucose metabolism compared to controls in: prefrontal cortex, partial, corpus callosum, left amygdala and left medial temporal lobe
-higher glucose metabolism compared to controls in: occipital lobe, right amygdala, right medial temporal lobe and right thalamus
-same levels of glucose metabolism compared to controls in: cingulate and temporal lobe
What are some issues with the methodology in Raines research?
-NGRI murders don’t represent all crimes—> lacks population validity
What are some strengths of the methodology used in Raines research?
+pet scans allow us to experiment on an active brain- not possible through post Mortums
+quasi- allows us to study something we can’t naturally manipulate
What are some ethical weaknesses of Raines research?
-no medication—> side effects/ withdrawal
-NGRI murderers may not be able to consent due to mental health issues
What are some social strengths of Raines research?
+could use brain imaging in court
+could put in place prevention strategies with people with brain abnormalities to reduce violence
