Who is Wilhelm Wundt + what did he do?
- Father of psychology
- 1st ever psychologist
- separated psychology from philosophy + biology
- opened the world’s first lab in 1879
- In Germany, Leipzig
What is Wundt’s Introspection?
Refers to the process of observing + examining your own conscious thoughts / emotions / inner mind
Procedure Wundt used for introspection
- used controlled conditions (same stimuli/standardised instructions/surrounding)
- observers shown object (ticking metronome) + asked to reflect on how they perceive it + give insight into nature of mental process
- report how stimuli made them feel + think
The technique is structuralism
what’s that?
Breaking down behaviour into basic elements (emotions / sensations / perceptions)
Why did Watson criticise introspection?
- criticised it for being too subjective and varying too much from person to person
- When objectivity is a feature of science
- Said u cant use the mind to think about the mind = should focus on observable behaviour only
How did Watson + Skinner attempt to overcome the limitations of introspection?
- Watson + Skinner proposed that truly scientific psychology should only study things that can be observed objectively + measured
= behaviourists focus on behaviour that they can see + use carefully controlled experiments
Brief explanation on the emergence of psychology as a science
- 1879: Wundt’s introspection [what]
- 1900: Freud’s Psychodynamic approach [person]
- 1913: Watson + Skinner ‘s behavioural approach [buys]
- 1950: Roger + Maslow’s Humanist approach [hard]
- 1960: Cognitive approach [carrots]
- social learning theory [silly]
- 1980: Biological approach [billy]
- 2000: Cognitive neuroscience
Evaluation of Wundt’s scientific method of introspection:
strength
+ Proved that human mind can be investigated scientifically contributed to the scientific study of human behaviour.
Used objective, quantitative, replicable procedure to investigate the human conscience (structuralism).
=Proved that psychology could be a valid experimental science.
= Influenced other psychologists (behaviourists + cognitivist) to continue with scientific investigation into human behaviour where cause + effect can be established + predictions can be made.
Evaluation of Wundt’s scientific method of introspection:
Limitations
- Wundt’s principle of introspection was criticised by the behaviourist as not being scientific.
Watson argued that although the method to investigate introspection were scientific = results were subjective + varied from person to person = cannot be verified and general principles cannot be established as cause and effect cannot be made.
Only observable behaviour can be objectively measured.
= Therefore introspection is unreliable + unscientific.
= Resulted in the emergence of behaviourism who adopted the scientific study of human behaviour but focused on the objective assessment of observable behaviour
Behaviourism: The learning approach
- Assumptions?
- Describe all behaviour as learnt
- Identified 2 important forms of learning: classical + operant conditioning
- Describe baby’s mind as a ‘blank slate’ that’s written by experience
- The basic processes that govern learning are same for all species = why they use lots of animal studies
Pavlov’s Classical conditioning
Learning by association when 2 stimuli paired
BEFORE CONDITIONING:
1. Food (UCS) = salvation (UCR)
- Bell (NS) = No response (UCR)
DURING CONDITIONING:
3. Food + Bell = Salvation (UC)
AFTER CONDITIONING:
4. Bell (CS) = Salvation (CR)
Pavlov’s Dog experiment
[Classical conditioning]
- Pavlov made ‘click’ sound with bell + gave dogs treat each time = dogs salivated to treats
- Dogs learnt to associate the sound of bell (stimuli 1) with treat (stimuli 2) = produced salivation to bell sound = conditioned
- Pavlov was able to show how a neutral stimuli (bell) can elicit a new conditioned response through association
Operant conditioning
Behaviour is shaped by consequences + reinforcement
+ / - reinforced = increases behaviour
+ / - punishment =reduces behaviour
- Positive reinforcement? (+adding smth)
- Negative reinforcement? (-removing smth)
- Positive Punishment? (+adding smth)
- Negative Punishment? (-removing smth)
- Positive reinforcement :
Adding smth to increase behaviour - Negative reinforcement :
Removing smth to increase behaviour - Positive punishment :
Adding smth to decrease behaviour - Negative punishment :
removing smth to decrease behaviour
The Skinner Box
[Operant conditioning]
- small animal (rat/pigeon) in special box
- each time rat activated lever in box = rewarded with food
= would continue to perform this behaviour
=positive reinforcement - to get food
/ each time pulled lever = no electric shock
= repeated behaviour to avoid shock
= negative reinforcement
Evaluation:
- 3 strengths ?
- 1 limitation ?
+
- supporting evidences ( Pavlov + Skinner + Little Albert study )
- Use of scientific studies + well controlled lab exp
- Real life application
-
- Ethical + practical issues with animal studies
Strengths of the learning approach:
1. supporting evidence
- Supporting evidence that all behaviour is learnt for all species
- Pavlov and Skinner both did studies (Pavlov’s dogs + the Skinner box)
= found that the principles of classical + operant conditioning can be applied to animals + extrapolated to human behaviour
+ Watson’s little Albert study proved that phobias are learnt via classical conditioning.
- Strength as these findings all validate both the classical + operant conditioning = making the learning approach more reliable + credible
- This increases our confidence in the learning approach + furthers our understanding into the factors affecting human behaviour as it gives us an insight into the different ways behaviour can be learnt from the environment.
- High control scientific studies used
- strength is that it’s based on well controlled research that uses scientific studies, that are objective and replicable in controlled environment.
- This is seen in Pavlov’s dog + Skinner’s box experiments - both of which use lab experiments with animals.
- Allows cause + effect to be established as extraneous variables removed + predictions about behaviour can be made = which has been influential in the development of psychology as a science.
- Real life application
- Principles of conditioning have real life application.
- Treatment based on classical (SD) or operant conditioning (Token economy) have been successful + effective in treating disorders including phobias + encouraging positive behaviour in patients who are institutionalised.
- These treatments require less effort than CBT and psychoanalysis and better suited to patients who struggle with / lack insight
- allowed for a better QOL for ps
Limitation
1. Ethical + practical issues
- There are ethical + practical issues with using animal studies to explain human behaviour.
- Animals involved in Skinner’s box were exposed to stressful conditions (shocks) which is not only unethical but may have also affected how they responded / their behaviour.
- Whilst these investigations furthered our understanding of human behaviour, it is important to note that animal studies cannot be completed extrapolated to humans due to the different evolutionary adaptations of our behaviour and humans are much more complex.
The learning approach - social learning theory (SLT)
Bandura agreed with the behaviourists that behaviour is learned from experience
but his SLT proposed a different way that ppl learn = through observations = imitations of others
Assumptions of the SLT
- Behaviour is learnt indirectly through vicarious reinforcement
- Through observations +imitations of others
Vicarious reinforcement
- Individual observe / pay attention to behaviour of others
- Imitate behaviour is its seen to be rewarded not punished
The role of mediational processes
Focus on how mental / cognitive factors are involved in learning
- Attention - noticing the behaviour
- Retention /encoding - remembering the behaviour
- Motor reproduction / imitation - performing the behaviour they observed
- Motivation - the will to perform the behaviour / reason to do it (whether behaviour was punished/ rewarded)
