Cognitive Approach- underlying assumption
Behaviour is based on internal mental processes.
Example of cognitive processes
memory, decision-making, perception, schemas.
What is a schema?
A cognitive framework of knowledge.
They are made as a result of experience.
Some schema is innate from birth. E.g. baby grasping, suckling, interactional synchrony.
Purpose: Keeps info so know what to expect/ make inferences about how to behave. E.g. going to a birthday party: Bring a present, dress nicely, have cake.
Cognitive approach: Models (2 types)
Theoretical and computer models.
Explain processes of behaviour we can’t see (internal).
-Explain what we do with cognitive information.
Computer models suggest cognitive processes function like computers do. (Input, storage, retrieval)
E.g. Artificial intelligence- Alexa, Siri, Google Home.
Theoretical models are diagrams based on research that explain cognitive processes. E.g. working memory model.
Cognitive neuroscience
Provides evidence for the cognitive approach.
fMRI, EEG, PET scans:
- functional Magnetic Resonance Imaging
- Electro Encephalogram
+use scanning to detect illnesses
Cognitive approach- A03
+ Cognitive science has application to the real world- Cognitive Behavioural Therapy- Useful in treating people with depression, schizophrenia, OCD- improving lives.
+ Considers both aspects of nature and nurture. Nurture= schemas/ experience, Nature= innate schemas. Because it considers both it is more accurate as theory which makes it more accurate.
+ Evidence- Alampay et al- gave images of the rat man- participants say if they see a face or a rat- what they saw depended on schema.
- Machine reductionism- breaking down something complex into mechanical parts- doesn’t take emotions into account.
The Social Learning theory- underlying assumption
Behaviours is learned through observation and imitation of others.
Learning occurs through directly, through classical and operant conditioning, but also indirectly.
What is vicarious reinforcement?
Reinforcement occurs through observation of someone else being reinforced for a behaviour.
This is a key factor in imitation.
Bandura’s Bobo doll experiment
Group 1: 12 boys and 12 girls were exposed to an aggressive model hitting a Bobo doll.
Group 2: 12 boys and 12 girls were exposed to a non-aggressive model
Group 3: 12 boys and 12 girls weren’t exposed to any model
Then the children were taken individually to a room with a Bobo doll with non- aggressive toys and aggressive toys such as a hammer.
Findings:
The children who had observed the aggressive model (group 1) were more aggressive than the children from the other two groups. Group 1 imitated specific aggressive acts that were displayed by the model. Boys imitated more physically aggressive acts than girls. There was no difference in the verbal aggression between boys and girls.
Conclusion:
This supports SLT as it shows that children imitate behaviour of role model even if the behaviour is aggressive.
The four meditational processes in learning
1) Attention- the extent to which we notice certain behaviour
2) Retention- how well the behaviour is remembered
3) Motor reproduction
4) Motivation
Identification
When an observer associates themselves with a role model and wants to be like the role model.
The social learning theory- A03
+ Research support- Bandura’s Bobo doll experiment- Supports SLT as it shows that children imitate behaviour of a role model.
+ Application- Parents can be aware that their bad behaviour could be passed on to their children- try to avoid doing these behaviours- E.g. Smoking
- Underestimates the influence of biological factors on social learning- Bandura makes little reference to biological factors- one finding of his research was that boys are more aggressive than girls regardless of the experimental condition- this might be due to levels of testosterone which is more present in boys than girls- leading to more aggressive behaviour
- Over-reliance on evidence from lab studies- Bandura’s ideas came from evidence from children in lab conditions demonstrating behaviour that might have been influenced by demand characteristics- children may have been behaving in a way that they thought was expected- Reduces validity as cant be generalised to how children learn in everyday life.
The biological approach- underlying assumption
The biological approach suggests that to fully understand behaviour we must look at biological processes within the body, such as, genes, neurochemistry and neurotransmitters.
What is concordance rate?
Concordance rate measures how often two individuals who are closely related have the same disorder.
What is genotype?
The particular set of genes that a person possesses.
What is a phenotype?
The characteristics of an individual determined by both genes and the environment.
The influence of genes on behaviour
Individuals may inherit a predisposition of illnesses which are carried on genes, from one generation to the next.
If an illness is caused genetically then we would expect two people who are closely related to be more likely to have it.
Genetic twin studies- Gottesman 1991
Gottesman (1991) carried out a sturdy and found concordance rates for Sz:
1% risk to world population
10% 1st degree relatives
17% Dz twins
48% Mz twins
He found a 48% concordance rate in MZ twins for schizophrenia. This suggests that if one twin has Sz there is a 48% chance that the identical twin will also have it. However as the concordance rate isn’t 100% there must be another factor (environment) which has an influence.
Evolution and behaviour
In the 19th century Charles Darwin proposed the theory of natural selection.
The main principle behind the theory is that genetically determined behaviour that enhances an individual’s survival will continue in future generations.
The Biological Approach- A03
+ Real-life application- our understanding of biological processes in the brain has led to the development of drugs which can treat mental illnesses- depression- sufferers are now able to live a relatively normal life thanks to these treatments.

The behaviourist approach- underlying assumption
ALL BEHAVIOUR IS LEARNT!
The behaviourist approach is only concerned with behaviour that can be observed and measured.
Behaviourists rejected introspection as it was too vague and difficult to measure.
Classical conditioning
Behaviour is learnt by association.
Occurs when two stimuli are repeatedly paired together.
E.g. Pavlov’s dogs
Operant conditioning
Behaviour is learnt through positive and negative reinforcement or punishment.
Positive reinforcement- Receiving a reward when a certain behaviour is carried out.
Negative reinforcement- Carrying out a behaviour to avoid something unpleasant.
Punishment- An unpleasant consequence of behaviour. E.g. being shouted at by a teacher for not doing homework- avoided through negative reinforcement.
Pavlov
Pavlov observed salivation in dogs.
He rang a bell- no salivation- no response
When he presented the dog with food the dog would salivate
After a few pairings (ringing the bell and presenting food) the dog learnt to associate the bell with food.
When he rang the bell the dog would salivated before being presented with food.
Thus, Pavlov was able to show how a neutral stimulus can produce a conditioned response through association.
