Q

What happens before conditioning in classical conditioning?

A

Unconditioned stimuli triggers a reflex response such as salivation, anxiety or sexual arousal. This is called the unconditioned response.

Q

What happens after conditioning in classical conditioning?

A

After pairing, the neutral stimuli produces the same response at the unconditioned stimuli. The neutral stimulus is now a conditioned stimulus producing a conditioned response

Q

Evaluation of classical conditioning

A

-Strength is supported by studies conducted on humans and animals. e.g. Pavlov demonstrates classical conditioning of salivation responses in his studies of dogs. This is important because it means there is firm evidence supporting the existence of classical conditioning.
-Weakness is it can only explain how a limited range of behaviours can be acquired. It only explains reflex responses so is only a partial explanation for learning of behaviour
-Strength is used in therapeutic applications such as systematic desensitisation and flooding. This shows classical conditioning is useful to psychologists as well as being of theoretical interest

Q

What were the findings of Pavlov’s study?

A

-Neutral stimuli didn’t initially cause salivation response, whereas the unconditioned stimuli caused immediate salivation
-After pairings of neutral stimuli and unconditioned stimuli,salivation occurred through the neutral stimuli
-No salivation was recorded in response to the neutral stimuli in backwards pairing
-Extinction of salivation could be seen as salivary volume declined after repeated presentation of the conditioned stimuli without the unconditioned stimuli

Q

What was the conclusion of Pavlov’s study?

A

A link can be made in the brain between an unconditioned stimuli and a neutral stimuli that occurs just before the unconditioned stimuli. This is called signalisation

Q

Evaluation of Pavlov’s study

A

-Strength is design of the study had clever features that reduced impact of extraneous variables and enhanced internal validity e.g. took place in a soundproof chamber to avoid external sounds distracting the dogs. These controls made it more likely that salivation in response to conditioned stimuli was due to conditioning rather than extraneous variables
-A weakness is its conducted on dogs so it isn’t generalisable. This is important because Pavlov believed his findings would generalise to humans and that isn’t entirely true. However, studies like little Albert show classical conditioning does take place in humans.
-Pavlov’s study has clinical applications in helping understand eating behaviours. Anita Jansen suggests overweight children have acquired very strong associations between cues that predict the arrival of food and salivation response, which causes overeating. This application of Pavlov’s research demonstrates its significance in developing therapies

Q

Evaluation of operant conditioning?

A

-Strength is supported by studies conducted by humans and animals. There are consistent findings regarding the ability to modify behaviour using reinforcement and punishment
-Weakness is it can only explain how existing behaviours are strengthened or weakened, not where behaviours originate. This shows operant conditioning is only a partial explanation for learning of behaviour
-Has many practical applications e.g. in childcare / education. For example giving a child a star for good work encourages them to repeat their good work. This shows operant conditioning is of use in the real world as well as being of theoretical interest

Q

What is continuous reinforcement?

A

Leads to rapid change in behaviour but the effects tend not to last

22
Q

What is partial reinforcement?

A

Reinforcement is irregular where we can vary either the ratio of behaviour to reinforcement or the interval between reinforcements. Partial schedules are written as F or V

23
Q

What are fixed and variable partial schedules?

A

-Fixed schedule is where reinforcer is given after a specified number of behaviours. The time is kept constant between intervals
-Variable schedule is given after an unpredictable number of behaviours. Time varies around mean length of time

24
Q

What is behaviour modification?

A

Where reinforcement is systematically used to increase the number of instances of desired behaviour e.g. Ford et al assessed head impact using helmet sensors and used individual monitoring to provide reinforcement to high-risk players. Mean impact intensity dropped by 3.9% thus behaviour modification improved safety

25
Q

What is shaping?

A

Used to encourage complex behaviours. This is done by reinforcing successive approximations of the behaviour. In other words you start by reinforcing behaviour vaguely like what you are seeking, but only continue the reinforcement each time the behaviour becomes a step closer to the target behaviour

26
Q

Evaluation of operant conditioning with reinforcement

A

-Strength of reinforcement schedules is they are supported by many studies conducted by humans and animals e.g. Latham and Dorsett (1978) found mountain beaver trappers responded better to variable ratio pay than fixed ratio pay
-A weakness is the properties of reinforcement doesn’t provide a complete account of human motivation. Our behaviour is a result of intristic motivation not just extrinsic motivations. This shows that reinforcement properties only provide a partial explanation for human behaviour
-Behaviour modifications have been used to treat a range of mental health problems e.g. Lovaas therapy involves intensive reinforcement in order to normalise some aspects of behaviour in children with ASD. This shows behaviour modification is of practical benefit to clients.

27
Q

What is modelling in SLT?

A

Modelling takes place when one individual displays a particular social behaviour in the presence of another. Models are people that can be of the same age or sex of the observer and are likeable and attractive

28
Q

What is vicarious reinforcement in SLT?

A

When an observer witnesses the model being rewarded for their behaviour

29
Q

What are the stages of social learning?

A

Attention to behaviour of model
Retention of observed behaviour
Reproduction of behaviour
Motivation to repeat behaviour due to vicarious reinforcement

30
Q

Evaluation of social learning theory

A

-Strength is supported by a number of studies conducted on humans and animals. Bandura’s studies showed children would imitate an aggressive model who demonstrated aggression on a Bobo doll if rewarded for doing so. Nicol and Pope showed chickens would selectively imitate high-status same-sex models in pecking a pad for food. This supports Bandura’s claims that behaviour can be acquired through observation and imitation
-Weakness is evidence that genetic factors are important as well as environmental influences. Kendler et al (2015) showed identical twins are more similar in levels of aggression than non-identical twins. This suggests social behaviour is genetically influenced and not a product of experiences of modelling.
However, Bandura didn’t entirely ignore biological factors. He claimed behaviours aren’t solely determined by social learning - it is the way its expressed that is learned not the actual urge to be aggressive
-Strength is it explains the alleged effect of media violence on aggression through violent TV, film and videogames. SLT helps us predict when this might occur e.g. when the aggressor is attractive or high status

31
Q

What was the aim of Bandura’s 1961 study?

A

To see whether aggressive behaviour could be acquired through observation of aggressive models

32
Q

What was the procedure of Bandura’s 1961 study?

A

-Lab experiment using matched pairs design
-36 boys and 36 girls ages 3-6 years selected from Stanford Uni Nursery in California
-Children were randomly allocated for one of the 3 conditions:
Aggressive group - observed aggressive adult models hurting the bobo doll
Non aggressive group - assembling mechanical toys
Control group - no model present

33
Q

What were the findings of Bandura’s 1961 study?

A

-Children who had witnessed the aggressive model were likely to completely or partially imitate aggression
-Children who had observed non-aggressive behaviour or those in the control group displayed less aggression
-Boys were more likely to imitate aggression shown by a same sex model than an opposite-sex model and more likely overall to imitate physical aggression

34
Q

What was the conclusion of Bandura’s 1961 study?

A

Social behaviour such as aggression can be acquired by imitation of models. Imitation is more likely when the modelled behaviour is gender - typical and when the model and observer are of the same gender

35
Q

Evaluation of Bandura’s 1961 study

A

-Strength is design of the experiment had clever features that reduced the impact of extraneous variables and enhanced internal validity of the study. Children taking part in each condition were matched for aggression, reducing the impact of individual differences. Observing the children one at a time controlled for conformity effects
-Weakness is it was conducted under artificial conditions. The experiment was in a lab in which aggression was measured through playing with a doll which is an atypical situation. This means the experiment lacked external validity.
-Can be applied to explaining how children can acquire aggression behaviours from adult models. This has important implications in policy around custody and parental contact where fathers have history of violence. This application of Bandura’s research demonstrates its significance in shaping our thoughts and social policy when it comes to risk of exposing children to violent adult models

36
Q

What was the aim of Bandura’s 1963 study?

A

To investigate whether a filmed model would have the same effect as a live model on children’s aggression

37
Q

What was the procedure of Bandura’s 1963 study?

A

-Lab experiment using independents group design
-48 boys and 48 girls ages 39-52 months selected from Stanford Uni Nursery
-Children were randomly allocated to one of four conditions:
Live aggression - watched an adult aggress towards a bobo doll
Filmed realistic aggression - watched behaviour displayed on a screen
Cartoon aggression - Watched on TV a model dressed as a black cartoon cat
Control group - Didn’t watch aggression

38
Q

What was the findings of Bandura’s 1963 study?

A

-Three experimental groups all displayed increased aggression:
83 Live, 93 filmed realistic, 99 cartoon
-The differences were not significant between the experimental groups
-There was a significant difference between the experiment groups and control

39
Q

What was the conclusion of Bandura’s 1963 study?

A

-Exposure to live or filmed aggression increases the likelihood of aggression in response to frustration, even if its a cartoon figure

40
Q

What was the aim of Bandura’s 1965 study?

A

To consider whether reinforcement / punishment of an aggressive model would influence the aggression displayed by observers

41
Q

What was the procedure of Bandura’s 1965 study?-

A

-32 boys and 32 girls ages 42-71 months from Stanford Uni Nursery
-Children were randomly allocated to one of three conditions:
Model rewarded - children saw a second adult praised for aggression with a chocolate and drink
Model punished - second adult scolded the model and spanked with a rolled up magazine
No consequence - model was neither punished nor reinforced

42
Q

What were the findings of Bandura’s 1965 study?

A

-Children in the model punished condition were significantly less aggressive than the other two groups

43
Q

What was the conclusion of Bandura’s 1965 study?

A

Vicarious reinforcement reduces imitated aggression. However, reinforcement is a more powerful influence than aggression

44
Q

Evaluation of 1963 and 1965 Bandura’s study

A

-Strength is design of the experiment had clever features that reduced the impact of extraneous variables and enhanced internal validity of the study. Children taking part in each condition were matched for aggression, reducing the impact of individual differences.
However, Bandura’s research only showed short-term effects, and aggression was only shown towards the doll. Therefore, the findings don’t necessarily explain aggressive behaviour in everyday life
-Weakness of both studies is elements of procedure could have cued children as to how they were expected to behave. Noble’s study reports that children may have expected to aggress the Bobo doll. This means the experimental procedure may lack external validity
-Strength is it has informed the development of Sabido method. Sabido pioneered the use of telenovelas to tackle specific social problems in countries all over the world. Viewers identify with popular characters who become role models and research has shown these role models prompt behaviour change. This demonstrates the significant contribution of SLT in promoting behaviours which are of benefit to individuals and wider society

45
Q

How does classical conditioning cause phobias?

A

Classical conditioning of a phobia involves learning to associate one stimulus with another. One stimulus triggers no fear and other stimulus already triggers fear response. Through association, neutral stimulus produces conditioned response of fear

46
Q

How does operant conditioning cause phobias?

A

Mowrer demonstrated operant conditioning by conditioning a rat to develop avoidance response to a shock - the rat was placed in a cage with electric shocks. The rat could escape but escape was negatively reinforced so avoidance response was learned
Mowrer said avoidance and negative reinforcement maintain phobias

47
Q

Evaluation of learning theory of phobias

A

-Strength is evidence from human/animal studies for role of conditioning and social learning in acquisition of phobias. This is proven through Rayner’s study for maintenance of fear and Cook / Mineka for social learning
Weakness is same phenonema associated with acquisition of phobias can’t be explained by learning alone. We don’t acquire fears of hazardous things through learning so this isn’t a complete explanation of phobias
-Strength is many real-world associations in therapies for phobias. This is illustrated through system desensitisation and flooding

48
Q

What is system desensitisation?

A

A behavioural therapy designed to gradually reduce phobia anxiety through principles of classical conditioning. A new response to the phobic stimulus is learned through counterconditioning

49
Q

How does system desensitisation work?

A

Anxiety hierarchy:
-Constructed by client and therapist
-List of situations related to phobic stimulus that provokes anxiety arranged from least to most frightening

Relaxation:
-Therapist teaches client to relax
-Clients can be taught to imagine themselves in relaxing situations

Exposure:
-Client is exposed to phobic stimulus while in a relaxed state
-Happens several times going up the anxiety hierarchy

50
Q

Evaluation of system desensitisation?

A

-Strength is these methods are effective in treatment of specific phobias. e.g. Gilroy et al (2003) compared clients receiving these methods for spider phobia with a control group. Results show the participants that did SD had less fear than control group
-Weakness is may not be as effective in all cases. SD only tackles behavioural phobias and less about symptoms linked to history of trauma

51
Q

What is flooding?

A

Exposing phobic clients to their phobic stimuli immediately.
-A learned response is extinguished when the conditioned stimuli is encountered without unconditioned stimulus. The result is the conditioned stimulus no longer produces the conditioned response
-It isn’t unethical but its an unpleasant experience so participants must give informed consent beforehand

52
Q

Evaluation of flooding?

A

-Strength is flooding is quick and efficient over alternatives. This means clients are free from their symptoms as soon as possible so treatment is cheaper
-Weakness is flooding may not be effective for social phobias. This may be because social phobias have cognitive aspects like unpleasant thoughts about a social situation. This means flooding cannot be the sole treatment on offer for phobias because it tackles behavioural responses only
