Approaches Flashcards
Who is labelled the ‘father of psychology?’
Wilhelm Wundt
Where was Wundt’s lab?
Leipzig, Germany.
How did Wundt change psychology?
- Separated it from it’s philosophical roots.
- First to use experimental methods
What were the two techniques introduced by Wundt?
- Standardized procedures
- Structuralism
What was Wundt’s pioneering method of studying psychology?
Introspection.
What is meant by introspection?
Introspection was the first systematic experimental attempt to study the mind through breaking up conscious awareness into basic structures of thoughts, images and sensations.
What is meant by structuralism?
Structuralism is isolating the structure of consciousness.
The stimuli Wundt et al. experienced were always presented in the same order and the same instructions were issued to all participants.

- Scientific
One strength of Wundt’s work is that some of his methods were systematic and well-controlled. All introspections were conducted systematically in a controlled lab setting, reducing extraneous variables being an interfering factor. In addition, procedures and instructions were carefully standardized so all participants received the same information and were tested in the same way. This suggests that Wundt’s research can be considered a forerunner to later scientific approaches in psychology,
setting the basis for these, such as the behaviourist approach. - Subjective data
One limitation is that other aspects of Wundt’s research may be perceived as unscientific modernly. Wundt’s data collection methods could be subjective as he relied on participants self-reporting their mental processes. This creates the issue of data being influenced by a personal perspective - possibly even leading to a social desirability response or response to demand characteristics. It is difficult to establish meaningful ‘laws of behaviour’ from such data. General laws are useful to predict future behaviour, which is one of the aims of science. This suggests Wundt’s early efforts and methodology were flawed, so would not meet criteria of scientific enquiry.
Why is Wundt significant in the study of psychology?
Wundt established the beginning of psychology as a science, separating it from it’s philosophical roots by employing techniques such as introspection, standardization and structuralism in a lab in Leipzig.
What is the behaviourist approach?
The behaviourist approach is a way of explaining behaviour in terms of what is observable and in terms of learning.
What is classical conditioning?
Learning through association.
Outline Pavlov’s experiment into classical conditioning.
- Pavlov showed how dogs could be conditioned to salivate at the sound of a bell if that sound was repeatedly presented at the same time they were given food (the UCS)
- Pavlovs dog learned to associate the sound of the bell (NS) with the food (UCS) and would produce the salivation response upon the sound of a bell.
- Thus, Pavlov was able to show how a neutral stimulus (the bell), can come to elicit a new learned response (conditioned response) through association.
What is the process of classical conditioning?
- Unconditioned stimulus → unconditioned response
- Neutral stimulus → no response
- UCS + NS → unconditioned response
- Conditioned stimulus (once NS) → conditioned response.
What is operant conditioning?
Learning through consequence, proposed to be an active process.
What are the three categories of operant conditioning?
- Positive reinforcement
- Negative reinforcement
- Punishment
What is positive reinforcement?
Receiving a reward when a certain behaviour is performed, increasing the likelihood for the behaviour to be repeated.
What is negative reinforcement?
- The avoidance of an unpleasant stimulus, with the outcome being a positive experience.
- This increases the likelihood of this behaviour being repeated due to reinforcement.
What is punishment in behaviourism?
- An unpleasant consequence of behaviour.
- Punishment decreases the likelihood of that behaviour being repeated.
Who demonstrated operant conditioning and what did they do?
- Skinner
- Skinner conducted experiments with rats and pigeons, with them being placed in a specially designed “skinners box”
- Every time the animal activated a level within the box it was rewarded with a good pellet, the animal would continue to perform this behaviour (positive reinforcement)
- Skinner also modelled negative reinforcement through conditioning the animals to perform the same behaviour to avoid an unpleasant stimulus, in this case, an electric shock.
Evaluate the behaviourist approach
- Well controlled research
One strength of the behaviourist approach is that is is based on well-controlled research. Behaviourists focus on measurement of observable behaviour in highly controlled lab settings. By breaking down behaviour into stimulus-response units, all possible extraneous variables can be minimized, and cause and effect relationships can be drawn. For example, Skinner could demonstrate how reinforcement influenced an animals behaviour. This suggests that behaviourist experiments have scientific credibility. - Oversimplification COUNTERPOINT
In counterpoint to establishing high degrees of control, there is potential that behaviourists may have oversimplified the learning process. From reducing behaviour to such simple components, behaviourists disregard an important influence on learning - human thought. Other approaches, such as social learning theory and the cognitive approach have accounted for the mental processes involved in learning. This suggests that learning is more complex than observable behaviour alone, and that private mental processes are also essential. - Real-world application.
Another strength of the behaviourist approach is that principles of conditioning have been applied to real world behaviors and issues. Operant conditioning is the basis of token economy systems, being used successfully in institutions such as prisons or psychiatric wards. Token systems operate by rewarding appropriate behaviour with tokens that can be exchanged for privileges. Also, classical conditioning can be used to explain why phobias are formed - and aiding in treatment such as systematic desensitisation and flooding. This increases the value of the behaviourist approach, being used for rehabilitation and treatment efforts. - Environmental determinism
One limitation of the behaviourist approach is that it sees all behaviour as conditioned by past conditioning experiences. Skinner suggested that everything we do is the sum total of reinforcement history. When something happens, for example, we may think ‘I made the decision to do that’ but, according to Skinner, our conditioning history determined the outcome. This refutes any possible influence of free will on behaviour. Skinner asserted himself that free will was an illusion. This is an extreme position and ignores the influence of conscious decision-making processes on behaviour.
Who contributed to social learning theory?
Bandura
What does social learning theory suggest?
Behaviour is learned from experience - through observation and imitation of others.
It also suggests that learning theory occurs with both direct and indirect classical and operant conditioning.
What is vicarious reinforcement
(social learning theory)
Vicarious reinforcement is reinforcement that is not directly experienced, occurring through someone else being reinforced for a behaviour.
What are the four mediational processes according to Bandura?
- Attention: the extent to which we notice certain behaviours
- Retention: how well the behaviour is remembered
- Motor reproduction: the ability of the observer to perform the behaviour
- Motivation: the will to perform the behaviour, according to whether the behaviour was rewarded or punished.
