Wilhelm Wundt established the first psychology lab
Opened in Leipzig, Germany in 1879. The aim was to describe the nature of human consciousness (the 'mind') in a carefully controlled and scientific environment—a lab
The same standardised instructions were given to all participants and stimuli (objects or sounds) were presented in the same order (standardised procedures). For instance, participants were given a ticking metronome and they would report their thoughts, images and sensations, which were then recorded
Wundt pioneered introspection, the first systematic experimental attempt to study the mind. It is a psychological method which involves analysing your own thoughts and feelings internally. Wundt used introspection to study sensation and perception.
Introspection led to identifying the structure of consciousness by breaking it up into the basic structures: thoughts, images and sensations. This marked the beginning of scientific psychology, separating it from its broader philosophical roots.
One limitation is that other aspects of Wundt's research are subjective.
P - One limitation is that other aspects of Wundt's research are subjective.
E - Wundt relied on participants selfreporting their 'private' mental processes. Such data is subjective. Participants may also have hidden some of their thoughts.
E - This makes it diffcult to establish meaningful 'laws of behaviour', one of the aims of science
L - Therefore Wundt's early efforts to study the mind were naive and would not meet the criteria of scientific enquiry.
Watson (1913) argued that introspection was subjective, in that it is influenced by a personal perspective. According to the behaviourist approach, 'scientific' psychology should only study phenomena that can be observed and measured.
Skinner (1953) brought the language and rigour of the natural sciences into psychology. The behaviourists' focus on learning, and the use of carefully controlled lab studies, would dominate psychology for 50 years
Following the computer revolution of the 1950s, the study of mental processes was seen as legitimate within psychology. Cognitive psychologists likened the mind to a computer and tested their predictions about memory and attention using experiments.
1980s The biological approach introduced technological advances.
Biological psychologists have taken advantage of recent advances in technology, including recording brain activity, using scanning techniques such as fMRI and EEG, and advanced genetic research.
The behaviourist approach is only concerned with studying behaviour that can be observed and measured. It is not concerned with mental processes of the mind. Introspection was rejected by behaviourists as its concepts were vague and diffcult to measure
Behaviourists suggest the processes that govern learning are the same in all species, so animals (e.g. rats, cats, dogs and pigeons) can replace humans as experimental subjects.
Pavlov's research — conditioning dogs to salivate when a bell rings: Before conditioning: UCS = food, UCR = salivation, NS = bell During conditioning: Bell and food occur at same time. After conditioning: CS = bell, CR = salivation Pavlov showed how a neutral stimulus (bell) can come to elicit a new learned response (conditioned response, CR) through association.
Operant conditioning refers to learning as an active process whereby humans and animals operate on their environment. Behaviour is shaped and maintained by its consequences.
Skinner's research — rats and pigeons, in specially designed cages (Skinner boxes). When a rat activated a lever (or a pigeon pecked a disc) it was rewarded with a food pellet. A desirable consequence led to behaviour being repeated. If pressing a lever meant an animal avoided an electric shock, the behaviour would also be repeated.
One strength of behaviourism is that it uses well-controlled research
P - One strength of behaviourism is that it uses well-controlled research
E - The approach has focused on the careful measurement observable behaviour within controlled settings.
E - Behaviourists have broken behaviour down into stimulus—response units and studied causal relationships.
L - This suggests that behaviourist experiments have scientific credibility
C - However this approach may oversimplify learning and ignore important influences on behaviour (e.g. thought). other approaches (e.g. social learning and cognitive) incorporate mental processes. This suggests learning is more complex than just what we can observe.
one strength is behaviourist laws of learning have real-world application.
P - one strength is behaviourist laws of learning have real-world application.
E - The principles of conditioning have been applied to a broad range of real- world behaviours and problems.
E - Token economy systems reward appropriate behaviour with tokens that are exchanged for privileges (operant conditioning). Successfully used in prisons and psychiatric wards
L - This increases the value of the behaviourist approach because it has widespread application.
One limitation is behaviourism is a form of environmental determinism.
P - One limitation is behaviourism is a form of environmental determinism
E - The approach sees all behaviour as determined by past experiences that have been conditioned and ignores any influence that free will may have on behaviour.
E - Skinner suggested that free will was an illusion. When something happens we may think 'l made the decision to do that' but our past conditioning determined the outcome
L - This is an extreme position and ignores the influence of conscious decisionmaking processes on behaviour (as suggested by the cognitive approach).
Albert Bandura agreed with the behaviourist approach that learning occurs through experience. However, he also proposed that learning takes place in a social context through observation and imitation of others' behaviour.
Learning related to consequences of behaviour — vicarious reinforcement.
Children (and adults) observe other people's behaviour and take note of its consequences. Behaviour that is seen to be rewarded (reinforced) is more likely to be copied = vicarious reinforcement
Mediational (cognitive) processes play a crucial role in learning.
There are four mediational processes in learning:
1. Attention — whether behaviour is noticed.
2. Retention — whether behaviour is remembered.
3. Motor reproduction — being able to do it. 4. Motivation — the will to perform the behaviour.
The first two relate to the learning, the last two to the performance (so, unlike behaviourism, learning and performance do not have to occur together).
People are more likely to imitate the behaviour of those with whom they identify. Such role models are similar to the observer, attractive and have high status.
The Bobo doll studies suggest that children are likely to imitate (model) acts of violence if they observe these in an adult role model. It is also the case that modelling aggressive behaviour is more likely if such behaviour is seen to be rewarded (vicarious reinforcement).
One strength is SLT emphasises the importance of cognitive factors.
P - One strength is SLT emphasises the importance of cognitive factors
E - Neither classical conditioning nor operant conditioning can offer a comprehensive account of human learning on their own because cognitive factors are omitted.
E - Humans and animals store information about the behaviour of others and use this to make judgements about when it is appropriate to perform certain actions.
L - This shows that SLT provides a more complete explanation of human learning than the behaviourist approach by recognising the role of mediational processes.
C - Recent research suggests that observational learning is controlled by mirror neurons in the brain, which allow us to empathise with and imitate other people. This suggests that SLT may make too little reference to the influence of biological factors on social learning.
One limitation is SLT relies too heavily on evidence from contrived lab studies
P - One limitation is SLT relies too heavily on evidence from contrived lab studies
E - Many of Bandura's ideas were developed through observation of children's behaviour in lab settings and this raises the problem of demand characteristics.
E - The main purpose of a Bobo doll is to hit it. So the children in those studies may have been behaving as they thought was expected.
L - Thus the research may tell us little about how children actually learn aggression in everyday life.
Another strength is SLT has real-world application.
P - Another strength is SLT has real-world application.
E - Social learning principles can account for how children learn from other people around them, as well as through the media, and this can explain how cultural norms are transmitted.
E - This has proved useful in understanding a range of behaviours such as how children come to understand their gender role by imitating role models in the media.
L - This increases the value of SLT as it can account for real-world behaviour.
In direct contrast to the behaviourist approach, the cognitive approach argues that mental processes should be studied, e.g. studying perception and memory.
Role of inference in the study of mental processes.
Mental processes are 'private' and cannot be observed so cognitive psychologists study them indirectly by making inferences (assumptions) about what is going on inside people's heads on the basis of their behaviour.
The idea of schema is central to the cognitive approach.
Schema are packages of information developed through experience. They act as a 'mental framework' for the interpretation of incoming information received by the cognitive system. Babies are born with simple motor schema for innate behaviours such as sucking and grasping. As we get older, our schema become more detailed and sophisticated
The information processing approach suggests that information flows through a sequence of stages that include input, storage and retrieval, as in the multi-store model (see page 32 of our Year 1 revision guide)
