Who is the father of Psychology
Wilhelm Wundt (1832-1920) is known as the ‘Father of Psychology’ as he moved psychology away from its philosophical roots to controlled research. He set up the first psychology laboratory in Liepzig, Germany, in the 1870s. Wundt also founded the Institute of Experimental Psychology and published one of the first books on psychology, helping to establish the subject as an independent branch of science.
What method did Wundt develop
Wundt developed a scientific method to study mental processes, such as the structure of sensation and perception. He called this method introspection.
What is Introspection
Introspection is a systematic analysis of our own conscious experiences of a stimuli. An experience is examined in terms of its component parts e.g. sensations, feelings, images etc.
What did Wundt claim about training an individual’s conscious mental processes
Wundt claimed that with sufficient training an individual’s conscious mental processes, such as perception, could be objectively reported by the individual as they occurred. For example, Wundt would ask people to focus on an everyday object (such as a metronome) and encourage them to look inwards and reflect on the sensations, feelings and the images that came to mind. This information could then be used to gain insight into the mental processes involved in perception
Where was Introspection used
Introspection was used in highly controlled studies. The use of controlled environments enabled Wundt to establish general theories about mental processes. His work paved the way for later controlled research and the study of mental processes e.g. by cognitive psychologists. However, Wundt later identified higher mental processes (such as learning, language, emotions, etc.) that could not be studied in a strictly controlled manner.
What did Wundt’s work lead to
Wundt’s work led to the development of the field of cultural psychology, based on general trends in behaviour of groups of people
Strengths of Emergence of Psychology as a Science
Wundt was the first to open a laboratory designated to the scientific study of psychological enquiry under controlled conditions facilitating accurate measurements and replication.
Wundt was the first psychologist to focus on understanding the psychological processes of perception etc. rather than philosophical or biological processes.
Wundt later recognised that higher mental processes were difficult to study using his procedures and this encouraged others to look for more appropriate methods and techniques, paving the way for approaches such as brain scanning techniques.
Weaknesses of Emergence of Psychology as a Science
Many modern psychologists argue that early behaviourists (e.g. Pavlov) made a greater contribution to the development of psychology as a science than Wundt did. They produced reliable findings, which Wundt did not, with explanatory principles that were generalisable – much more in keeping with the scientific approach.
Strengths of Introspection
Focus on mental processes through introspection can be seen as the forerunner of the cognitive approach.
Introspection is still sometimes used in modern scientific psychological research (e.g. Csikszentmihalyi & Hunter, 2003), and in areas such as therapy and studying emotional states. This demonstrates its value as one way mental processes can be investigated.
Weaknesses of Introspection
Studies using introspection may not be valid. Many psychologists would argue that several aspects of our mind are outside of our conscious awareness (e.g. research by Nisbett & Wilson, 1977) and so cannot be reported by an individual.
Behaviourist Approach Key Assumptions
- Concerned with observable behaviour that can be objectively and scientifically measured.
- All behaviour is learned from the environment and can be reduced to a stimulus-response association.
- There is little difference between the learning that takes place in humans and non-human animals. Therefore, research can be carried out on animals as well as humans.
Classical Conditioning
The behaviourist approach suggests that all behaviour is learnt rather than being innate or inherited from parents. One way in which behaviour can be learned is via classical conditioning, which is learning through association. A stimulus produces the same response as another stimulus because they have been consistently presented at the same time.
Operant Conditioning
The basic idea behind Skinner’s theory of operant conditioning (Skinner, 1938) is that organisms spontaneously produce different behaviours and these behaviours produce consequences for that organism. Some of these consequences may be positive and some may be negative. If the consequence of a behaviour is positive then the behaviour is likely to be repeated. If the consequence is negative then the behaviour is much less likely to be repeated.
Difference between Classical and Operant Conditioning
Operant conditioning is different to classical conditioning. Responses are reinforced in operant conditioning but not in classical conditioning. Classical conditioning explains the acquisition of a response (e.g. a phobia) while operant conditioning explains the maintenance of a response.
Strengths of the Behaviourist Approach
The behaviourist approach enhanced the scientific status of Psychology by using strict scientific methods, being objective, and producing verifiable findings.
The behaviourist approach has led to several useful treatments such as systematic desensitisation (classical conditioning) and token economy (operant conditioning). However, focusing solely on behaviour neglects the whole person. Treatments using conditioning do not get to the root cause of a patient’s problem, and so it is likely that when the therapy has ended the patient will return to their original behaviour.
Weaknesses of the Behaviourist Approach
The behaviourist approach is environmentally reductionist because it focuses on a lower level of explanation than other approaches. Stimulus-response associations lack meaning when attempting to explain complex human behaviours, such as attachment. The behaviourist approach is also environmentally deterministic. According to behaviourism, human behaviour is entirely determined by the environment, there is no account taken of a person’s free will to decide how to behave.
The behaviourist approach has been criticised because it uses non-human animals. Critics claim this tells us little about human behaviour because humans have cognitive factors and emotional states that influence their behaviour.
Social Learning Theory Key Assumptions
Behaviour is learned through experience, specifically through observation and imitation within a social context.
Social Learning Theory Model
Modelling, Imitation, Identification, Vicarious Reinforcement and Mediational Processes
Modelling
In order for social learning to take place models must carry out the behaviour to be learnt. A live model could be a parent, teacher or peer. A symbolic model could be someone in the media.
Imitation
A lot of the behaviour people acquire is learnt though copying (imitating) the behaviour that is modelled by others.
Identification
We are more likely to imitate the behaviour of a model who we admire or who is similar to us in some way (e.g. same age and gender). In order to identify with the model, observers must feel that they are similar enough to the model that if they performed the same behaviour, the consequence would be the same for them as it was for the model.
Vicarious Reinforcement
Individuals learn by observing the behaviour of others and the reward and punishment they receive. People to not need to experience rewards or punishments directly in order to learn from them. People may learn behaviours, but not perform them because they have also learned that the behaviour is likely to be punished if displayed.
Mediational Processes
Attention, Retention, Motivation and Motor Reproduction
Attention
First the observer must pay attention to the model (attend to their actions)
Retention
Secondly the observer must be capable of retention (remember the behaviour that has been modelled).
Motivation
Thirdly the observer must be motivated to imitate the behaviour (because they want the same reward the model received.
Motor Reproduction
Finally the observer must consider themselves to be physically and psychologically capable of reproducing the behaviour. People can learn a behaviour but still not reproduce it because they are not motivated to, or they are not capable of that behaviour.
Bandura (1961) Procedure
Bandura conducted a study involving 36 male and 36 female children aged 3-7years of age. The children had to observe a model acting either aggressively or non aggressively with a bobo doll. Some of the children saw a same-sex model, others saw a different sex model. In the experimental conditions the model displayed aggressive acts towards the bobo doll such as striking it with a mallet and shouting “POW!”. After the children observed these aggressive acts, they were made to feel frustrated. They were shown attractive toys but told they were not allowed to play with them. The children (one by one) were then taken to a room which had some toys including a bobo doll. The children were observed for 20 minutes.
Bandura (1961) Findings
The results found that the children who observed the aggressive model reproduced the same aggressive behaviour towards the bobo doll, whereas the children who observed the non-aggressive model, showed no aggression to the bobo doll. 33% of children who observed and heard verbal aggression repeated what they had seen and heard. However 0% of children in the non aggressive group displayed verbal aggression. Boys were more aggressive than girls, and imitation of aggression was greatest when the model was the same gender as the observer (identification)
Strengths of Social Learning Theory
Social learning theory recognises the importance of both behavioural and cognitive factors (mediational processes) when examining how people learn new behaviours, unlike the behaviourist approach (classical and operant conditioning).
Weaknesses of Social Learning Theory
Mediational factors have to be inferred so we cannot measure the extent of their influence. SLT does not try to explain mediational processes, it leaves this to cognitive psychologists.
Social learning theory can be criticised because it does not take into account cause and effect. Studies have found that young people who have deviant attitudes seek out peers with similar attitudes, rather than becoming deviant because of their peers.
Social learning theory sees behaviour as environmentally determined and so ignores the role of biology in behaviour. However, Bandura (1961) found in his experiment that boys were more aggressive than girls, regardless of the experimental situation they were in. Boys might be more aggressive because of the hormone testosterone which means it is biologically determined.
Social learning theory is able to explain behaviours such as aggression, but not so able to explain the learning of abstract notions, e.g. fairness, justice etc. which cannot be observed directly.
The Cognitive Approach Key Assumptions
- Psychology should be the study of internal mental processes, e.g. memory, perception etc.
- The importance of the role of schema.
- It is appropriate to make inferences about cognitive processes
- The use of models of explanation – theoretical and computer models.
- Possibility of combining cognitive processes and biological structures (cognitive neuroscience)
The Role of Models in Cognitive Psychology
Making inferences means going beyond the immediate evidence to make assumptions about mental processes that cannot be directly observed. Theoretical models in cognitive psychology (such as the multi-store model of memory) are simplified representations based on current research evidence. Models are often pictorial in nature, represented by boxes and arrows that indicate cause and effect in mental processes. Models are often incomplete and are frequently updated. For example, the Working Memory Model was first proposed in 1974, but a fourth component was added in 2000.
Real life Models in Cognitive Psychology
Cognitive psychologists have also made use of computer models to explain mental processes. Using computers as an analogy, information is inputted through the senses, coded into memory and then combined with previously stored information. Computer models are often used to explain memory, long-term memory is like a hard-disk and RAM is like working memory. Like working memory, RAM, is cleared and reset when a task has been carried out.
The Role of Schema
Schema are mental representations of experience, knowledge and understanding. They help organise and interpret information in the brain. For example, schema for specific events are based on expectations of how to behave in a different situation (e.g. a restaurant or a classroom) or in different roles (e.g. as a prison guard or a student). Schema are useful because they help us predict what will happen in our world based on our previous experiences. Schema also enable us to process vast amounts of information rapidly. Finally, schema prevent us from becoming overwhelmed by environmental stimuli. However, schema can distort our interpretation of sensory information. Schema could also lead to perceptual errors or inaccurate memories. They can cause biased recall as we see what we expect. Negative or faulty schema may have a negative impact on mental health (e.g. the negative triad).
Cognitive Neuroscience
Cognitive and biological processes can be integrated, leading to a discipline known as cognitive neuroscience. This is the scientific study of the neurological structures, mechanisms, processes and chemistry which are responsible for our thinking processes.
