Approaches Flashcards
Wilhelm Wundt
In 1873 he published the ‘Principle of Physiological Psychology’. Established psychology as a unique branch of science. Opened the first psychology lab in Leipzig, Germany in 1879. Developed the theory of introspection- process of gaining knowledge of one’s mental/ emotional state by observing our mental processes like memory and perception.
Introspection
Process of gaining knowledge of one’s mental/ emotional state by observing our mental processes like memory and perception.
Griffiths (1994)- fruit machine
Introspection on fruit machine gamblers- asked them to think aloud while playing.
Csikzentmilyi and Hunter (2003)- happiness
Used introspection to study happiness in their work in the area of positive psychology.
Empiricism
Knowledge comes from observation and experience alone.
Introspection Evaluation
- Not reliable- cannot be measured because they are unobservable.
- Other researchers were not reliably reproducing the same thing.
- Other psychologists were conducing reliable scientific studies.
- Not particularly accurate.

Behaviourism
Behaviour is learnt through classical and operant conditioning.
Classical Conditioning
Learning through association.
Operant Conditioning
Learning through reinforcement.
Classical conditioning process
An unconditioned stimulus can gradually become associated with a neutral stimulus to create a conditioned stimulus and response.
Pavlov (1902)- dogs
- Classical conditioning involves association of an unconditioned stimulus with a response with a neutral one to create a new conditioned stimulus and response- triggered a dog to salivate when a bell was rung.
- Unconditioned stimulus (food) = Unconditioned response (salivation)
- Neutral stimulus (bell)
- Unconditioned stimulus (food) + Neutral stimulus (bell) = Unconditioned response (salivation)
- Overtime: Conditioned stimulus (bell) = Conditioned response (salivation)
Operant Conditioning Process
Works through positive reinforcement, negative reinforcement and punishment. Positive reinforcement works for reinforcing behaviour through rewards. Negative reinforcement reinforces behaviour by removing unpleasant feelings. Punishment weakens negative behaviour.
B F Skinner (1948)- rats
- Operant conditioning suggests behaviour is reinforced by positive or negative reinforcement- studied rats in cages.
- Positive Reinforcement- hungry rat in cage with a lever. Rat would knock the lever and be given a food pellet. They quickly learnt that they would be given food by knocking the lever.
- Negative Reinforcement- subjected the rats to eclectic shocks. If the rat knocked the lever it would stop the current, learning to go to the lever to stop the unpleasant current.
- Punishment- designed to weaken or eliminate a response.
Watson and Rayner (1920)- Little Albert
Applied Classical Conditioning to cause a phobia of white rats in ‘Little Albert’. Paired a white rat with a loud clanging sound. Little Albert was conditioned to fear anything white and fluffy including the investigator’s beard.
Behaviourism Evaluation
+ Practical applications/ usefulness- helped with treatments like systematic desensitisation.
+ Scientific method- Skinner manipulated the IV and was able to measure the rats behaviour- establish a cause and effect relationship.
- Both theories are based on animals- human behaviour is different.
- Reductionist- doesn’t take into account nature.
Social Learning Theory
Behaviour is learnt through imitation.
Bandura (1961)- SLT
A group of children were split into 2 separate groups. Half were exposed to an adult role model interacting aggressively with a life size Bobo doll, while the other half were exposed to an adult interacting calmly with the Bobo doll. The children who were exposed to a more aggressive adult were seen to be more verbally and physically aggressive afterwards with the same Bobo doll.
Modelling
People imitate behaviour displayed by role models.
Identification
People are more likely to imitate behaviour displayed by role models they relate to.
Imitation
Behaviour is copied and replicated depending on the characteristics of the model, the ability to replicate the behaviour and the consequences.
Vicarious Reinforcement
Seeing punishment or reward can affect the likelihood of imitation.
Mediational Processes
People must perform internal mediational processes to imitate.
Attention
Behaviour must capture ones attention to be imitated.
Retention
Behaviour must be memorable to be imitated.
Reproduction
Behaviour must be able to be replicated/ the person must have the ability to reproduce it to be imitated.
Motivation
The will to perform the behaviour.
Social Learning Theory Evaluation
+ Practical Applications- useful in understanding criminal behaviour.
+ Research support from Bandura’s study.
- Problem with causality- role models may have nothing to do with someone’s behaviour- they may just be the way they are.
- A problem with complexity- too reductionist. Disregards any other influence on behaviour like genes, locus of control, etc.
Bandura and Walters (1963)- rewards
Children who saw models being rewarded for aggressive acts were more likely to show a high level of aggression in their own play.
Akers (1998)- criminals
The probability of someone engaging in crime increases when they’re exposed to models that commit crime and identify with these people.
Ulrich (2003)- violence and rewards
Found that the strongest cause of violent behaviour in adolescence was association with delinquent peer groups where violence was modelled and rewarded.
Siegal and McCormick (2006)- personality
Criminals may not be influenced but just have a deviant attitude.
Cognitive Approach
All behaviour is preceded by a thought.
