What is introspection according to Wundt?
The first systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures, thoughts, images and sensations.
This method involved people recording their conscious thoughts in a lab setting.
In what year did Wundt establish the first lab for psychological study?
1879
What methods did Wundt use in his lab?
- Scientific methods
- Standardised instructions
- Controlled settings
- Easily replicated experiments
Who is known as the father of psychology?
Wundt
What was the main contribution of the behaviourist approach?
Focused on visible and observable behaviours, making psychology more objective and scientific.
What approach used lab experiments to infer cognitive processes?
Cognitive approach
What does the biological approach measure and how?
- Biological influences such as hormones
- Conducts experiments in highly controlled settings
What is cognitive neuroscience?
A merger of the cognitive and biological approaches that uses scanning techniques to link brain regions to feelings or disorders.
What was significant about Wundt’s lab?
It was the first lab dedicated to psychological enquiry.
Why are Wundt’s methods sometimes criticized?
They are considered too subjective to be classified as scientific, as they measure private mental processes that are not observable.
Wundt used lab experiments which may have created contrived situations that may lack mundane realism and therefore have low external validity.
What is the key assumption of the behavioural approach?
All behaviours are learned through the consequences of our own behaviour.
What research methods are commonly used in the behavioural approach?
- Lab experiments
- Assessment of observable behaviours
Define classical conditioning.
Learning a new behaviour by the process of association.
What is an unconditioned stimulus (UCS)?
A stimulus that produces an unconditioned response (UCR).
What does a neutral stimulus (NS) produce?
No response.
What happens when an unconditioned stimulus (UCS) is associated with a neutral stimulus (NS)?
The NS becomes a conditioned stimulus (CS).
What is a conditioned response (CR)?
The response produced by a conditioned stimulus (CS) after conditioning.
What did Pavlov observe in his experiments + results?
- Observed salivation at feeding time of dogs
- Gave food (UCS), causing salivation (UCR)
- Started ringing bell (NS) while giving food (UCS)
- After a couple of cycles, stopped giving food with the bell
This suggests that because a previously neutral stimulus caused the same reaction as a UCS, the dogs learned to associate the ringing bell to food
What is positive reinforcement?
Encouraging repetition of a behaviour by giving a reward.
What is negative reinforcement?
Encouraging repetition of a behaviour by taking something unpleasant away.
What is punishment in operant conditioning?
Discouraging repetition of a behaviour with a negative consequence.
What did Skinner observe in his experiments with rats + results?
- Observed rats in a puzzle box
- When rat would move around, it would accidentally knock a lever
- The lever caused food pellets to drop into the container
- After a while, pushing the lever would no longer cause food to drop into the container
What he found:
Rat eventually learned to knock the lever whenever it wanted food, as pushing the lever was positively reinforced with food (reward)
When the rat stopped receiving food for pushing the lever, it eventually stopped pushing the lever altogether, suggesting that the behaviour was extinct
What happens to behaviour when it is reinforced?
The behaviour is repeated and strengthened.
What occurs if behaviour is not reinforced or is punished?
The behaviour will be extinguished.
