Learning psychology Flashcards
What are the assumptions of the learning approach
The major influence on human behaviour is learning from our environment
Laws of learning are the same for all species
Psych should be study of observable behaviour, learning is stimulus-response
Scientific methods lead to knowledge
What are the 5 ethical considerations of The scientific procedures act 1986
Care over caging
Avoiding discomfort and distress
Suitably qualified researchers
Cost-benefit analysis
Look for alternatives
What are the 3 factors Bateson said you need to take into account
Degree of suffering - low
Quality of research - high
Certainty of benefit - high
What is classical conditioning
learning by association where natural reflexes are paired with neutral stimuli
What are the 5 key terms for classical conditioning
Unconditioned stimulus
Unconditioned response
Neutral stimulus
Conditioned stimulus
Conditioned response
What is extinction and spontaneous recovery in CC
Extinction: If a CS is repeatedly presented without the UCS the CR will disappear
Spontaneous recovery: Temporary return of extinct response after a delay
What was the aim of Pavlov’s study
Investigate the reflex response of salivation to see how reflexive behaviour can be produced in new situations.
What was the sample of Pavlov’s study
25 years, 23 studies, 35 various dog breeds
What was the procedure of Pavlov’s study
Baseline condition - put meat in dogs mouth to measure salivation to compare
Control condition - presented dog with food
Experimental condition - Presented dogs with metronome, buzzer and tuning fork - no salivation so NS. Paired food arrival with metronome a few times then presented it on its own.
Did forward and backward conditioning
What were the findings of Pavlov study
Baseline - secretion 1-2 seconds after food in mouth
Control - secretion started after 5 seconds and 6 drops collected after 15 seconds
Experimental - secretion 9 seconds after metronome and 11 drops collected after 45 seconds
Forward produced salivation but backwards didn’t
What was the conclusion of Pavlov’s study
‘Signalisation’ in the brain links the metronome to food and gives a reflex response of salivation
2 positives of Pavlov’s study
+ Standardised procedure - Kept in same environment and same stimulus’
+ Practical applications - help to treat phobias
2 negatives of Pavlov’s study
- Anthropomorphic - humans more complex than dogs
- Eco validity - special chamber
What was the aim of Watson and Rayners study
Too see if classical conditioning could create an irrational fear and to see if that fear could be transferred over to other animals and objects
What was the procedure of Watson and Rayners study
First assessed little albert at 9 months old to ensure no fear of white rat
White rat presented at same time as 2 metal bars banging together creating distressing Nosie
After a while the baby was distressed without the metal bars
The replaced by white items like cotton wool and fur
What was the findings of Watson and Rayner
After 5 trials he was scared of the rat
After 12 he was scared of any white object
What was the conclusion of Watson and Rayner
A conditioned emotional response can occur after a few pairings of stimuli are presented
2 positives of Watson and Rayner
+ cause and effect - lab setting
+ confidentiality - pseudonym
2 negatives of Watson and Rayner
- Population validity - 1 person so cant generalise
- eco validity - not in natural setting
What is the difference between reinforcement and punishment
Reinforcement has the effect on increasing the likelihood of behaviour being repeated but punishment decreases the likelihood of negative behaviour repeating
What is vicarious reinforcement
See a role model being reinforced for their behaviour so imitate to receive the reinforcement
aim of bandura 61
investigate whether young people will imitate an aggressive role model
Sample of bandura 61
72 participants from Stanford university nursery aged 3-5 with 36 males and females
Procedure of bandura 61
Participants assigned to 1 of 10 conditions
Sat opposite a model and observed for 10 mins before taken to a mild aggression arousal room
Then taken to room with bobo doll mallet and nail gun
Observed through 2 way mirror and recorded every 5 seconds on their pre determined code for 20 mins - 5 point scale for aggression
Findings of Bandura 61
More likely to copy same sex with boys more than girls
Boys more physical, same for verbal aggression
Children in non aggressive model showed little aggression
Conclusion of Bandura 61
Children are likely to copy behaviour which they are unlikely to produce of watching a role model do it.
Explains acquisition of new responses
Aim of Bandura 63
Investigate if kids would imitate aggression when it was seen on a screen
More likely to imitate a cartoon model?
Sample of Bandura 63
96 3-5 year olds from Stanford uni nursery 46 boys and girls
Procedure of Bandura 63
Real life aggression model - Saw a role model playing normally then aggressively in a structured way
Human filmed aggression - watched same model be aggressive to bobo doll on pre recorded projector
Cartoon aggression - black cat being aggressive to bobo doll with artificial flowers and grass
Findings of Bandura 63
Mean aggression scores:
Real life - 83
Human film - 92
Cartoon - 99
Control - 54
still more boys than girls
Conclusion of Bandura 63
Exposure to aggressive models increased chance of aggression
Violent acts were clearly observed and imitated
