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
What was the methodology for loftus and palmer’s research?
-two experiments were conducted
-Both were experiments
-Both had independent groups
Experiment1– had 45 students
Experiment 2– had 150 students 
What was the procedures for experiment 1 of Loftus and Palmers study?
– 45 American university students were split into five groups
– All groups were shown seven short video clips of car accidents.
– They were then asked to fill in a short questionnaire with the critical question of about how fast with the cars going, when they – each other
– The five verbs that they could fill the space in with were: hit, smashed, collided, bumped and contacted
What were the procedures for experiment 2 of Loftus and Palmer study?
– 150 American University students were split into three groups (of 50)
– They were then shown a short film that showed a multi-vehicle car accident
– They were then asked a series of questions, including one critical question:
Group one was asked how fast with a car is going when they smashed into each other
Group 2 was asked how far with the car is going when they hit each other
Group 3 wasn’t asked about the speed of the vehicles
-A week later, participants where then asked did you see any broken glass in the video?
What were the findings for experiment one in Loftus and Palmer’s study?
The main speed answered for each verb:
-smashed- 40.8mph
-collided- 39.8 mph
-bumped- 38.1 mph
-hit- 34.0 mph
-contacted- 31.8mph
What were the findings of experiment2 for Loftus and Palmer’s research?
When the verb smashed was used, participants were more than twice as likely to report seen broken glass (with 16 people saying they had 24 Saying they had not), then those who had the verb hit (with 7 people saying they had and 43 people saying they had not )or those who where in the control condition (with 6 in the control condition saying they had and 44 in the control condition saying they had not)
