what is the aim of Banduras 1961
To find out if children would show more aggressive behaviour if exposed to an aggressive role model and less aggressive behaviour if exposed to a non-aggressive role model. Also, to see if the sex of the role model and the child made a difference, specifically to see if the children were more likely to imitate a same sex role model and if boys were more aggressive than girls.
what is the IV of banduras 1961
Bandura manipulated two sets of IVs: (1) whether the role model was aggressive or non-aggressive, (2) whether the role model was the same sex or opposite sex to the child; there was also (3) a Control condition where the children did not see a role model at all.
Bandura also studied a naturally-varying IV: (4) whether the child was male or female.
This makes the study both a lab experiment and a natural experiment. It has a Matched Pairs design because each child was only in one condition but they were matched on their level of starting aggression.
what were the results of banduras 1961 study?
The children who observed an aggressive role model showed a lot of verbal and physical aggression that resembled the scripted routine the model had acted out.
There was very little aggressive behaviour in the Non-Aggressive Model condition and in the Control condition; around 70% had a score of zero for aggression. Children from the Non-Aggressive Model condition spent the most time sitting quietly.
In general, a male role model had a bigger influence than a female role model: the aggressive male model produced more aggression; the non-aggressive male model produced more calm.
Some of the more significant figures have been highlighted:
Compare the boys’ physical aggression after a male aggressive role model (average 25.8 acts) to the girls’ after a female aggressive role model (5.5)
Compare the girls’ verbal aggression after a female aggressive role model (13.7) to the boys after a male aggressive role model (12.7)
Mallet Aggression is high even for the Control group (about 13 acts on average, regardless of gender), but a non-aggressive role model reduces it to 0.5 for girls, 6.7 for boys
Even in the Control group, non-imitative aggression is higher for boys (24.6) than girls (6.1)
what is the dv of banduras 1961 study?
Bandura’s observers recorded the number of verbal, physical, mallet and gun-play aggressive actions the children carried out; they also counted the number of acts of non-imitative aggression.
what was the procedure in banduras 1961 study?
The basic procedure is described above.
24 children (12 boys, 12 girls) formed a Control group who didn’t watch any role model. The other 48 children were split into experimental groups of 6, each group containing 3 boys and 3 girls.
Half the children saw a same-sex role model; half saw an opposite sex role model.
what is the sample of banduras 1961 study?
72 children, 36 boys and 36 girls, aged 3-5, recruited from Stanford University Nursery School.
what were the conclusions of banduras 1961 study?
Bandura concludes that behaviour can be learned by imitation even if it hasn’t been reinforced (as Skinner suggested). In fact, complex patterns of behaviour can be learned through imitation without needing reinforcement for each part.
The male role model was much more influential than the female and boys’ showed a much greater tendency to engage in physical aggression. Bandura links this to cultural expectations. He suggests that even at a young age, boys and girls have learned what society expects them to behave like, based on TV, stories and family.
Verbal aggression was sex-typed, with girls imitating the female role model and boys imitating the male role model. This suggests that, if there are no strong cultural expectations, people will imitate the model they most identify with, even if the model is a stranger.
Aggressive models seem to weaken social inhibitions. You can see this by comparing the model conditions to the Control group who acted ‘naturally’. It is interesting to see how much Mallet Aggression and Gun Play went on in the Control group – presumably cultural expectations tell children they ought to play with mallets/guns in this way.
what is the aim of banduras 1963a study?
To find out if children would become more aggressive if exposed to an aggressive role model in film or in a less-realistic cartoon compared to watching a live model. Bandura also wanted to test the popular idea that watching filmed aggression might be “cathartic” (making people calmer because it “vents” their aggressive feelings).
what is the IV and DV of banduras 1963a study?
IV
Bandura manipulated two sets of IVs: (1) whether the aggressive role model was real, filmed or a cartoon character, (2) whether the role model was the same sex or opposite sex to the child; there was also (3) a Control condition where the children did not see a role model at all. (NB. There was no Non-Aggressive Model this time)
Bandura also studied a naturally-varying IV: (4) whether the child was male or female.
This makes the study both a lab experiment and a natural experiment. It has a Matched Pairs design because each child was only in one condition but they had been matched on starting levels of aggression.
DV
Bandura’s observers recorded the number of verbal, physical, mallet and gun-play aggressive actions the children carried out; they also counted the number of acts of non-imitative aggression.
what was the sample and procedure of banduras 1963a study?
Sample
96 children, 48 boys and 48 girls, aged 3-5, recruited from Stanford University Nursery School (an opportunity sample).
Procedure
The basic procedure is described above. There was no Non-Aggressive Model condition, but an extra condition was added where children watched a film in which the female adult model was dressed as a cartoon cat, while following the script with the Bobo Doll.
what are the results of banduras 1963a study?
You can see at once that the Control group carried out half as much aggression as the other groups.
However, there’s no significant difference between live models and filmed or cartoon models.
Picture
When you look into the data, the cartoon produced more non-imitative aggression (100) but less imitative aggression (24) whereas the human models were the other way around.
Because Bandura filmed this study, there is qualitative data as well as quantitative data (all the footage in the video clips you see are actually from this variation).
QUALATIVE:
The children were shocked by the aggressive female model, with one boy saying “That ain’t no way for a lady to behave!” and a girl saying “That girl… was acting just like a man!”
Boys and girls were admiring of the aggressive male role model: one boy said “Al’s a good socker, he beat up Bobo! I want to sock like Al!” and a girl said “He’s a good fighter, like Daddy!”
conclusion of banduras 1963a study?
Bandura concludes that children will imitate filmed aggression in the same way as live aggressive role models.
Bandura also concludes that watching filmed violence is NOT cathartic. Instead of becoming less aggressive after watching aggressive film or cartoons, the children showed more aggression.
Bandura was surprised to see how much the cartoon role model was imitated, because he expected there to be less imitation as the role model became less realistic (because the children would identify with it less). However, the cartoon aggression seemed to weaken social inhibitions generally, because there was less imitative aggression but more non-imitative aggression in this condition.
IV and DV of banduras 1965 study?
IV
Bandura manipulated two sets of IVs: (1) whether the aggressive role model (“Rocky”) was rewarded, punished or there were no consequences, (2) whether the role model was the same sex or opposite sex to the child, and (3) whether the child received no incentive or a positive incentive (reward).
Bandura also studied a naturally-varying IV: (3) whether the child was male or female.
This makes the study both a lab experiment and a natural experiment. It is a Matched Pairs design because the children saw different role models but had been matched on starting aggression. It also has a Repeated Measures design because the children were in the No Incentive condition then put in the Positive Incentive condition.
DV
Bandura’s observers recorded the number of verbal, physical, mallet and gun-play aggressive actions the children carried out; they also counted the number of acts of non-imitative aggression.
results of banduras 1965 study?
Bandura doesn’t report the exact scores for this study but you can see the results in this graph.
Picture
You can see that the Model Reward condition produced about the same imitation from girls (mean 2.8) and boys (3.5) as the No Consequences condition.
The Model Punished condition produced much less imitation, especially among the girls (mean 0.5).
After Positive Incentive, the imitation increased significantly for girls and boys and is very similar across all conditions of the model, with the girls’ scores much closer to the boys’ (all >3).
aim of banduras 1965 study?
To find out if children would be more likely to imitate a role model they see being rewarded (vicarious reinforcement) and less likely to imitate a role model they see being punished (vicarious punishment). He also wanted to see if the children would be more likely to imitate if they themselves were offered rewards.
evaluation that can be used for all banduras studies:
2 strengths:
Bandura also used two observers behind the one-way mirror. This creates inter-rater reliability because a behaviour had to be noted by both observers otherwise it didn’t count.
g- both genders
evaluation that can be used for all banduras studies:
2 weaknesses:
he main criticism of all Bandura’s studies is that they lack validity. The children were put in a strange situation, exposed to some unusual adult behaviour and given toys to play with which encouraged them to act unnaturally. For example, a Bobo Doll is designed to be hit and knocked over (it bounces back upright); children would suppose the experimenters wanted them to play with the Bobo Doll in this way. This sort of behaviour is called demand characteristics, because the participants do the stuff they think the researchers demand of them.
There are many ethical issues with Bandura’s studies. The major issue is harm and the wellbeing of participants. The children may have been distressed by the aggressive behaviour they witnessed and the aggressive behaviour they learned from the study may have stayed with them, going on to become a behavioural problem. Participants are supposed to leave a study in the same state they entered it, which may not have happened here. This is an example of what the BPS Code of Ethics calls “normalising unhelpful behaviours”.
sample and procedure of banduras 1965 study?
Sample
66 children, 33 boys and 33 girls, aged 3-5, recruited from Stanford University Nursery School (an opportunity sample).
Procedure
The basic procedure is described above. There was no Non-Aggressive Model condition, but all the other conditions were filmed. The model (“Rocky”) went through a scripted routine of aggressive behaviour towards a Bobo Doll.
In the Reward condition, the experimenter arrived a praised Rocky for his “superb aggressive performance” and gave Rocky sweets, which he ate.
In in the Punishment condition, the experimenter called Rocky “a big bully” and hit him with a rolled-up newspaper.
In the No Consequences condition, nothing happened to Rocky.
The children were placed in the Observation Room for 10 minutes and secretly observed – this is the No Incentive condition.
Then they were brought juice and told they would get more juice and sticker books if they could imitate Rocky. They were asked to “show me what Rocky did” and “tell me what Rocky said.” If there was imitative aggression in response, they were rewarded straight away. This is the Positive Incentive condition.
what is classical conditioning:
GENERAL PRINCIPLES OF CLASSICAL CONDITIONING
Classical conditioning focuses on STIMULUS RESPONSE, the conditioning of REFLEXES. Human reflexes include a fear response, eye blinking, knee-jerking, fear and breathing. Fear can be conditioned, as fear is a reflexive response, this can explain phobias.
Most behaviour goes beyond just a reflex so classical conditioning is quite limited.
Classical conditioning is a theory of learning that examines how a response is associated with a stimulus to cause conditioning.
A stimulus is something that produces a response, which in classical conditioning is either a reflex or an automatic behaviour. These responses to stimuli are involuntary responses i.e. showing a startle response like fear to a sudden noise.
Classical conditioning argues that there is an association between an UNCONDITIONED STIMULUS (UCS), which is a naturally occurring stimulus, and an existing UNCONDITIONED RESPONSE (UCR), which is a naturally occurring response.
describe extinction from classical conditioning:
Refers to when the association (CS and CR) is no longer there, it is extinguished. So when the association is extinguished the bell (CS) will no longer cause salivation (CR). This can be achieved by presenting the UCS (food) without the CS (bell). The association between the two stops, and therefore the bell returns to being a neutral stimulus. So, the UCS of food presented without CS of bell results in CR of salivation. The CS of bell will then begin to result in no response, therefore the bell returns to original state of NS.
describe spontaneous recovery from classical conditioning:
This is when, after extinction, you might find that a previously paired conditioned response to a conditioned stimulus suddenly and without reconditioning reappears for no reason. For example above, despite extinction, you ring a bell and the response of salivation occurs again.
