Wilhelm Wundt
First person to call himself a psychologist, known as the father of psychology, he founded the institute of experimental psychology, he published one of the first books on psychology to stabilise the subject as an independent branch of science. He opened the first experimental lab in Leipzig Germany, helping to shape psychology as a science. The lab was designed to aid the scientific study of psychological inquiry using controlled conditions that could facilitate replication of results to study the structure of sensation and perceptions. He intended to focus on the psychological processes of perception and structuralism- theory of consciousness, involved the use of introspections, self reports of sensations, views, feelings and emotions, he used scarification methods, it was recorded under strictly controlled conditions in a lab using the same stimuli, the same reaction times and the same instructions give to the participants, they had to focus on present experiences, making the research highly reliable
Introspection
“The first systematic and experimental attempt to study the mind/ mental processes by breaking down conscious awareness into basic structures of reflections, thoughts, images and sensations.”
Evaluation of introspection and the emergence of psychology as a science (8)
1) Watson criticised Wundt’s idea of introspection and whether psychology was emerging as a science.
Introspection produces subjective data which varies from one individual to the next, and therefore introspection is not objective or very reliable. Wundt’s methods are very subjective compared to the objectivity of scientific processes. There are many difficulties when trying to objectively study unobservable matter. (-)
2)
Introspection has been criticised because it is not very scientific or accurate. Research conducted by Wilson claims that psychologists have little knowledge about some behaviour and attitudes that might exist outside of conscious awareness (e.g. racism).
Introspection would not be able to uncover and help us understand
these thought processes (-)
3) Introspection can be criticised because it fails to explain HOW the mind works and the processes involved in hinking about a particular topic/doing an activity. Psychologists cannot see how thoughts are generated and introspection cannot be properly observed (so might not be very scientific) (-)
4) Introspection has the advantage that it has helped to develop other approaches in psychology (such as behaviourism via Watson). The focus on mental processes through introspection can be seen as a forerunner to develop the cognitive approach by Beck and Ellis (+)
5)
Introspection has the advantage of being extremely scientific. It shares the same qualities as the scientific subjects of Chemistry, Biology and Physics, for instance all of these subjects make predictions about form hypotheses. There is a high level of control of variables as all of these subjects including Psychology study behaviour in a laboratory setting (+)
6) A disadvantage of Wundt’s work is that there have been greater contributions to the development of psychology by early behaviourists, e.g. Pavlov, than by Wundt. Pavlov for example produced reliable findings with explanatory principles (classical conditioning) that were generalizable, which is more in line with the scientific approach (-)
7) Introspection has the advantage that it is still used today in areas of therapy that study emotional states. For instance introspection can be used in cognitive therapy in order to try to get patients to alter their negative thinking and turn them into positive thoughts. Therefore introspection can still be applied to contemporary therapy used in modern society (+)
8)
Wundt supports and advocates the idea of reductionism. He believed consciousness could be broken down (or reduced) to its basic elements without sacrificing any of the properties of the whole. He studied internal mental processes by deconstructing them down into measurable units such as perception, senses and experiences. (+)
Behavioural approach
A way of explaining behaviour in terms of what is observed in terms of learning
Classical conditioning
“This is learning by association. A neutral stimulus is repeatedly paired with an unconditioned stimulus. The neutral stimulus will eventually produce the same response that was produced by the unconditioned response alone”
Behavioural approach assumptions
All behaviour is learned and involves the same process for animals and humans
Watson rejected introspection because it was too vague and difficult to measure
Behaviourism maintains more control and objectivity within research and relies on laboratory experiments
Pavlov and the salivating dogs
Method of learning involves building up an association between two different stimuli so that learning can take place, dogs can be conditioned to salivate to the sound of a bell, if the sound of the bell is repeatedly presented at the same time as the food, both of these stimuli would then be paired together to cause a learning response so that the dog would learn to associate the sound of the bell with food and will then salivate, at the end of the conditioning process the dog will earn to salivate when they hear the sound of the bell alone (temporal contiguity)
-generalisation, discrimination, extinction
Evaluation of classical conditioning (8)
There is research evidence to support the idea of classical conditioning being able to explain the development of learning and phobias. Evidence comes from Pavlov and his research on dogs, as well as the Little Albert study by Watson and Rayner. However, we must be cautious when using the research findings from Little Albert because the study was conducted in a laboratory setting and we might find that different results might be gained from a different setting.
Therefore the findings might be quite weak and might lack ecological validity when considering how important and effective classical conditioning actually is (+)(-)
2)
Classical conditioning is successful in explaining how learning can occur in animals and young children. However classical conditioning might not be very strong in explaining how adults learn new behaviours. Therefore classical conditioning is limited to only explaining learning in young children and animals only (-)
[Answer]
3)
The psychologist Menzies criticises the behavioural model, especially the idea of classical conditioning. He studied people that had a phobia of water (hydrophobia), and he found that only 2% of his sample had encountered a negative experience with water (due to dassical conditioning and learning). Therefore, 98% of his sample had a phobia of water but had never had a negative experience involving water, which means that they had not learnt to become frightened of water. Therefore; how did these people get their phobia of water if they had not learnt it? Other findings include 50% of people who have a dog phobia have never had a bad experience involving a dog, so therefore learning cannot be a factor in causing the development of the phobia (-)
4)
A strength of the behavioural model is that it is a model that can be easily tested and measured in a scientific way by using observations in a laboratory. The behavioural model relies on observing behaviour that can be directly seen and measured in a highly controlled setting. This helps aid objectivity and replication (+) |
5)
The behaviourial model can be criticised because it views humans and animals as passive recipients who have machine like responses to stimuli in the environment. Animals and humans can easily learn new behaviours unquestionably and apparently have little or no conscious thought at all. This minimises their free will. (-)
6)
A strength of Pavlov’s research is that it has helped apply dassical conditioning to treatments of psychological disorders.
For example, classical conditioning has helped form treatments such as flooding and systematic desensitisation which are based on the components of dassical conditioning and association (+)
7)
The behavioural model would be criticised by the biological approach in Psychology. The behavioural model would ignore the role of genes, hormones, evolution and neural mechanisms that are responsible for behaviour. There is very strong research evidence from a range of psychologists that behaviour is caused and determined by genes, a key example is schizophrenia, whereby genetics have been identified as the main cause of the illness (this has been identified by gene mapping). The biological approach would criticise the behavioural approach and state how it is very unlikely that someone could learn to be schizophrenic (via classical conditioning). Therefore other models in psychology should also be considered when looking at how behaviours develop (-)
8) A disadvantage of classical conditioning is that is can be viewed as being deterministic because it ignores the role of free will in people’s behavioural responses. Classical conditioning anticipates an individual will respond to a conditioned stimulus with no variation, which is not accurate. People are not passive states and they do have some control over how they might respond to an association between two stimuli. This can lead to explanations for behaviour that are incomplete and inconsistent. (-)
Operant conditioning
Method of learning focused on behaviour producing consequences such as punishment, positive or negative reinforcement
Skinner box
A cage which has loud speaker, lights, a level, a door and a floor which could be electrified. One hungry rat at a time would be placed in the box and allowed to freely run around
Positive reinforcement
The rat might accidentally press the level and the rat would be rewarded by a food pellet which would drop into the Skinner box
Negative reinforcement
That rat could also learn that by pressing the lever they could avoid something unpleasant, rat could learn that by pressing lever they could prevent being electrocuted
Skinner box
Extinction means that when the rat presses the lever but no longer receives a reward (food pellet); the rat soon learns that pressing the lever leads to no rewards. The rat will therefore stop pressing the lever as it has learnt that it leads to no more rewards.
• Spontaneous recovery: Following extinction (see above), if the rat presses the lever and does then suddenly receive a food pellet, the rat will very quickly learn that pressing the lever results in a food pellet.
The rat will learn this link very quickly and “spontaneously recover” what he had previously learnt
• Schedules of reinforcement: This means that there are different methods of reinforcement that might occur: some examples include:
• A) Continuous reinforcement: Every time the rat presses the lever they will always receive a food pellet
B) Fixed Interval: The rat presses the lever and only receives a food pellet during a fixed time only, e.g. every 30 seconds
• C) Fixed ratio: The rat must press the lever for a fixed number of times and then it will receive the food pellet
Evaluation of operant conditioning
• There is research evidence to support the idea of operant conditioning in the real world. Token economy is used in institutions such as prisons and hospitals and acts as a form of behaviour modification. Token economy works by rewarding appropriate behaviour with tokens which can be exchanged for privileges.
Research conducted by Paul and Lentz used token economy to treat patients who had schizophrenia, and it was found that their behaviour became more appropriate. (+)
Skinner’s research involving the Skinner box can be criticised. Skinner ignores the concept of free will. He suggests that past experiences involving operant conditioning will affect future behaviour, and people/animals have no control over their actions or the behaviours they show. This is a deterministic view of behaviour which does not account for free will and the fact that a human/animal has a choice over how they behave. (-)
3) A strength of the research conducted by Skinner using the Skinner box is that he relied on the experimental method. He used highly controlled conditions to discover the relationship between variables so that he could establish a cause and effect relationship, e.g. pressing the lever causes the rat to learn food will arrive (reward) (+)
4) The research by Skinner is on the nurture side of the nature/nurture debate. This would state that learning occurs due to environmental factors and external stimuli rather than due to nature and biology. Therefore by
manufating factors in the environment this can have an effect on learning and behaviour, and is supported
5) A problem of operant conditioning is that it is rooted in the behaviourist approach in Psychology and would ignore the biological approach. The biological approach would argue against the behavioural approach and would state that behaviour cannot be learnt, but instead behaviour is heavily influenced by the role of genes, hormones and biochemical/neural mechanisms. Therefore other approaches in psychology must also be considered when examining the influences upon behaviour, and operant conditioning/learning cannot explain all behaviours e.g. do people learn how to be aggressive, or could it be caused by genes and hormones? (testosterone) (-)
6) A disadvantage of operant conditioning it that its effectiveness in shaping learning and behaviour has been discussed compared to social learning theory and the cognitive approach. Operant conditioning might not be as successful as learning from others (social learning) or as successful as the internal mental processes that go into learning (cognitive approach) (-)
Social learning theory
Explains how behaviours can be learned .
- Modelling: it requires a person to carry out they behaviour so that the observe can learn it (can be live or symbolic)
- Imitation: children learn behaviours through imitating behaviours displayed by the model, this is quicker than using classical or operant conditioning. Characteristics of the model, observers perceived ability to perform the behaviour shown, observed consequences of behaviour.
- Identification: the extent to which the observer relates to the model and feels that he is similar to them so that they could experience the same outcome as the model, the person would aim to be like the model as much as they could, children are likely to identify with a model if the same sex as themselves
- Vicarious reinforcement: individuals do not need to experience rewards of punishment directly in-order to learn new behaviours, they can observe the consequences by observing the model
Meditational processes
Social learning places great emphasis on this, the learning must form a mental representation of the behaviour being displayed by the model and the likely consequences of the behaviour
Attention
Retention
Motor reproduction
Motivation
Evaluation of social learning theory (6)
Akers (1998) found that criminals seem to engage in more criminal behaviour when they are exposed to a model that they can highly identify with e.g. same gender/age range. (+)
2)
A strength of Social learning theory is that it is more effective when the model is very similar to the observer (rather than dissimilar). If the observer is similar to the model, it makes it easier for the observer to visualise themselves in the place of the model and feel like they are having the same experience. Fox (2009) found evidence to suggest that when an observer played a computer game that had a model that looked very similar to themselves, they were more likely to engage in the same behaviours as the model (+)
3) Social learning theory can be criticised because it ignores other potential influences on behaviour. For example Social learning theory would ignore the role of neurochemistry which could cause people to behave in certain ways. For example Bandura found in his experiment that boys were more aggressive than girls, regardless of the experimental situation they were in and this was due to the hormone testosterone making boys more aggressive. (-)
4) An advantage of Social learning theory is that it is an evidence-based approach with a great deal of supporting research evidence. For example, Bandura demonstrates that children are able to learn behaviour through observing the behaviour of an adult (see the bobo doll experiment below) (+)
5) The Social learning theory can be criticised because it sees behaviour as being determined by the environment (environmental determinism) rather than being caused by other factors such as genetics or innate behaviour. This can pose a criticism because genetics is a very big factor that can determine human behaviour, and the social learning theory ignores this factor. (-)
6) Social learning theory focuses on the nurture side of the nature/nurture debate and looks at how the environment and role models shape behaviours. The theory does not look towards nature and how genes could influence behaviour overall, it is all about the environment (-/+)
Bandura (1961)
36 male and female children between 3-7 years of age, the children had to watch the model act aggressively or non aggressive against the bobo doll, in the experimental conditions the model displayed aggression such as striking the bobo doll with a mallet and shouting POW! After the children observed aggressive acts, they were made to feel frustrated, shown attractive toys but not allowed to play with them. Then one by one the children were taken to a room which had some toys including bobo dolls, thy were then observed for 20 minutes. 33% of children who observed and heard verbal aggression repeated what they saw and heard, however 0% of children in non aggressive followed. Boys were more aggressive than girls and aggression was greatest when the model was the same gender as themselves observer
Bandura evaluation
-conducted in a lab
-lacks ecological validity
-the use of bobo dolls has been criticised
-we do not know if the actions continued throughout- only short term
-ethical issues
-real life implications: like looking out for shows ur children are watching
Cognitive approach- key assumptions
-behaviour is influenced by thoughts, both conscious and unconscious
-internal mental processes e.g. memory, perception can be studied
-mental processes can involve schema
-theoretical and computer models can be used
-it is possible to make inferences about cognitive processes
-neural mechanisms can be combined with cognitive processes (cognitive neuroscience)
Role of models
Models can be used to provide testable theories about mental processing and these can be studied scientifically and inferences made. Making inferences means going beyond the immediate evidence to make assumptions about mental processes that can’t be directly observed. Theoretical models in cognitive psychology (such as msms) are simplified representations based on current research evidence, often pictorial in nature and represented by boxes and arrows to c show cause and effect in mental processes, they are often incomplete and are frequently updated mental processes are a form of information processing which can be compared to that of a computer, cognitive psychologists have made use of computer models to explain mental processes
Role of schemas
Schemas are mental representations of experience, knowledge and understanding, often help organise and interpret info in the brain. Schemas for specific events are based on expectations of how to behave in different situations or in different roles, they are useful because they help us predict what twill happen in our world based on our previous experiences, they also help us process vast amount of info rapidly, and also prevent us from being overwhelmed by environmental stimulus. (Event/role schemas)
However schemas can distort our interpretation of sensory info, they can also lead to perceptual errors or inaccurate memory, and can cause biased recall as we see what we expect. Negative or faulty schemas may have negative impact on mental health
Evaluation of cognitive approach
1) A strength of the cognitive approach is that it has many applications in different areas of Psychology. For example social cognitions can help psychologists understand how to form impressions of other people and how we might form cognitive errors and biases. Cognitive Psychology might also explain the development of faulty negative thinking which can aid our understanding of abnormal psychology e.g. phobias (+)
AF
2) A strength of the cognitive approach is that it emphasises scientific methods such as laboratory experiments when collecting data. This means that high levels of control can be exercised in these settings and cause and effect relationships can be identified between the independent and dependent variables. This also makes the research more
objective and scientific. (+)
3) A criticism of the cognitive approach is that it focuses heavily on internal mental processes which are often ignored by other models in Psychology. For instance the biological approach would focus on genetics, biochemistry and neuroanatomy as factors that could cause behaviour to occur. The cognitive model would focus solely on thoughts and internal mental processes, and the biological model would ignore these factors (-)
4) The cognitive approach can be criticised it does not give a full picture about what is really going on inside the working mind/brain. Psychologists and scientists still need to make inferences about cognitive processing which might be based on limited information available from research/experiments. It is questionable whether psychologists can really
understand and explain thinking by using inference alone. (-)
6) A criticism of the cognitive approach is the idea of Soft determinism. This is the idea behaviour is constrained by the environment or biology. The cognitive approach views behaviour as being determined by internal cognitive factors but would ignore biology or the environment. However, biology might have a big impact upon cognitive thinking, for example there is a great deal of evidence that depression and negative thinking might be genetic (therefore Biology does affect
cognition to an extent) (-)
Bartlett- study of the role of schemas
The study was conducted in a laboratory
• English participants were asked to read a Native American folk tale called, “The war of the Ghosts” which was an unfamiliar and strange story because it came from a very different culture. It had an unfamiliar and unusual story structure compared to an English story
• Participants had to read the story, and then after different lengths of time they had to recall the story as accurately as possible (to test their schemas and recall)
• The results of the study showed that all English participants changed the story to fit their own schema. They reconstructed the story in order to recall it better.
• The details of the story became more “English” and contained elements of the English culture.
Details of “ghosts” were left out in the recall
The order of the story was changed to be more “logical”
• Changes were made when recalling the story, for example, “canoes” were changed to “cars” and “bows” and arrows changed to “guns”.
• As more time passed between reading the story and recalling the details, it was found that participants seemed to remember less information.
• The conclusion to this study is that people use their own schemas to help them interpret and remember information, and this is dependent upon culture to an extent.
• Schemas are important when studying internal mental processes.
