#Exam 2- Learning Approach Flashcards
evaluation
What is the summary of classical conditioning
If a behaviour is repeated so many times it becomes learnt. It’s why we expect a response from certain stimulus.
What is a UCS
Smell of food ( something that produces a response naturally )
What is the UCR
Natural reflex to the UCS- salivation at the smell of food
What is a CS
A learnt response
What is the CR
When a neutral stimulus becomes a conditioned stimulus
What is extinction
When the CR disappears
What is spontaneous recovery
When CR returns in a weakened form
Difference between discrimination and generalisation
Discrimination is when it only occurs for that specific item, where’s generalisation is when the response is for all similar items
What supports classical conditioning
Pavlov and his study on dogs
Difference between classical conditioning and operant conditioning
Classical conditioning focuses upon the idea that if a behaviour is repeated so many times it becomes learnt however operant is the idea that we learn behaviour if it was reinforced
Positive and negative reinforcement are part of which theory
Operant conditioning
What theory does SLT work alongside
Conditioning
Summary of SLT
Behaviour is learned through the observation of role models
What are attention, retention and reproduction
Attention- paying attention to a behaviour
Retention-remembering that behaviour
Reproduction- the reproduction of the behaviour
What is vicarious reinforcement
When a person is rewarded for hard work ( positive reinforcement)
How can systematic desensitisation help overcome fears
Aims to replace undesirable fear by replacing it with desirable one such as relaxation
How does flooding work
Having to face your fear head on
How does classical conditioning explain phobias
anxiety provoking UCS is associated with a once neutral stimulus
How does operant conditioning explain phobias
Phobias become worse when repeatedly reinforcing the avoidance of a mildly fearful thing
How can social learning theory explain phobias
We learn phobias through vicarious reinforcement, we observe that fear from a role model, remember it and then repeat that behaviour
Difference between the three Bandura studies
1961- violence witnessed in real life
1963- the violence shown was from a film
1965- see if reward or punishment at the end of violence effected levels of aggression
What is the classic study in learning psychology
Watson and Raynor- see if a 9 month old boy could be conditioned into having a phobia of a white rat.
What was the aim of Becker’s study and how many took part
To investigate how prolonged exposure of TV affected eating behaviours of 63 Fijian girls
Why is anorexia an issue
Affects 1/200 adolescents
85% of young women worry about their looks
Affects 1% of 15-18 year old girls
How does operant conditioning explain anorexia
Positive reinforcement for being thin or negative for being fat
How does social learning theory explain anorexia
People imitate their role models
What is the psychodynamic explanation of anorexia
Women do it as a regression to child ( prevent growing older )
Aim of the learning psychology practical
Conduct an observation into males and females behaviour on public transport covert ppt observation
What were the results of our practicals
2.44 on chi squared analysis, lower then CV of 3.84. This means the results suggest it’s over 5% due to chance factors not gender
evaluation of operant and classical conditioning
s- thorndike and skinner (positve effects from behaviour means it is repeated)
c-classical conditioning and pavlovs dogs- biological theories
o-ignores biological explanation for behaviour
u- reductionist, however explains why we shouldn’t expose children to violence
t-scientifically controlled experiments
evaluation of social learning theory
s- williams et al- 80% of programmes watched by high amounts of people- encourages asbo
c-charlton et al found media and environmental factors also to blame
o-depends on motivation also there is a biological explanation
u-shows why we shouldn’t show children violence
t- standardized procedure
strengths of systematic desensitisation
ethical active involvement clear rationale can be done at a distance wills and edwards- SD is more effective
what are the weaknesses of systematic desensitisation
can’t do it for fears of flying
only useful for certain phobias like spiders
not as useful for evolutionary phobias
what are the strengths of flooding
very quick way of curing a phobia
wolpe- car phobic girl shows flooding to be more effective in general
what are the weaknesses of flooding
might increase phobia ie Barlett had parctical implosion and got to point where she couldn’t not see spiders
what was procedure for bandura 1961
72 ppts matched pairs
each child either saw, aggressive or non aggressive or control
watched modelled aggression to bobo doll and see if they would repeat.
results/conclusions of bandura 1961
children who witnessed aggression more aggresisve, opposite for control and non aggressive. boys imitate same sex more
not all behaviour learned from reinforcement
procedure of bandura 1963
96 children
same apart from control was replced with a woman dressed as cat while follwing a script with a bobo doll
results of bandura 1963
no difference between live action and cartoon, control group carried out half aggression
children showed more aggression
evaluation of both the 1961 and 1963 Bandura
G-not generalisable to adults but can be generalised to both genders
R- reliable as it has standardized procedure
A- stops children looking at violent content
v- high IV low EV ( higher in 63 as done at home)
E- consent ?
What was the procedure of bandura 1965
33m 33 f
Children watch short movie before going in room with bobo doll
At end of movie either reward or punished or neither
What were the results and conclusion of bandura 1965
Repeated if behaviour rewarded
Boys imitated more
Younger children copy physical aggression
Vicarious reinforcement does increase imitation of aggressive behaviour
Evaluate bandura 1965
S-rideout and Williams et al Generalisable Links to social learning theory Applicake to pegi Standardised procedure
What were the results and conclusions of little Albert
Proves phobia could be conditioned
NS associated with unconditioned stimulus ( loud bang ). Caused fear of white rat
Conclusion- children can have fears conditioned into them. Similar things could also gain a fear
Strengths and weaknesses of little Albert
G- one young boy not generalisable R-controlled experiment A-applied to see how people get phobias V- high internal validity and low ecological validity E-poor ethics CDCDWP
Becker’s procedure
Naturalistic experiment tracking changes which have occurred over time
63 adolescent girls 3 weeks and then 3 years after
Eat 26 survey on attitudes towards eating
Results of Becker
Respondents with TV 3 times more likely to have eat 26 score greater then 20
Self induced vomiting went from 0% 1993 to 11.3% In 1995
40% thought loosing weight was better careers
What was Becker’s conclusion.
Impact of TVS profound
Cultural traditions were against purging which changed when TV introduced
Ideal body weight changed
Strengths of Becker
Studies such as Hamilton and Waller
High ecological validity as it takes places in natural environment
Large sample size
Applicable as it shows how TV can impact eating behaviours
Weaknesses of Becker
Gynocentric- only females
Not an ethical diagnosis made on participants
Consumerism effects - EV- lower internal validity
What is the alternative biological explanation of anorexia
Holland et al - high concordance rates between MZ twins 55% and DZ twins 7%
What is the psychodynamic explanation of anorexia
Regression to childhood shown by women to prevent growing older
What is the hypothesis from our learning psychology practical
Males will show more polite behaviours than females on public transport to and from college
What is the aim of our practical
To conduct an observation into males and females behaviour on public transport comparing good manners against bad. Using covert ppt participation
What was the procedure to your learning practical
Sample 400 ppts
Created coding scheme such as moving back, thank you to driver, giving up seat
Bad manners, pushing and making noise
Pilot study where behaviour was noted down
Results of learning psychology practical
Observed 162 males and 147 females. 35 males has bad manners whereas 47 females did. Over 5% due to chance factors under critical value of 3.84
No correlation between gender and good manners
Strengths of learning psychology practical
Standardised coding system, creates reliability for study
High EV
Gathered both Ql and Qn data
Weaknesses of learning psychology practical
Opportunity sample not generalisable to country
Un ethical- not informed
May have missed behaviour
