WHAT YOU NEED TO KNOWLearning Theory: behaviorism Learning Theory: Social Learning Theory Cognitive Approach Biological Approach Psychodynamic Approach Humanistic Approach
Classical conditioning is learning through association and was first demonstrated by Ivan Pavlov365体育登录. Pavlov showed that dogs could be conditioned to salivate at the sound of a bell if that sound was repeatedly presented at the same time that they were given food.
First the dogs were presented with the food, they salivated. The food was the unconditioned stimulus and salivation was an unconditioned (innate) response.
Then Pavlov sounded the bell (neutral stimulus) before giving the food. After a few pairings the dogs salivated when they heard the bell even when no food was given. The bell had become the conditioned stimulus and salivation had become the conditioned response.
The dogs had learnt to associate365体育登录 the bell with the food and the sound of the bell and salivation was triggered by the sound of the bell.
Skinner argued that learning is an active process. When humans and animals act on and in their environment consequences follow these behaviors. If the consequences are pleasant they repeat the behavior but if the consequences are unpleasant they do not repeat the behavior.
A hungry rat was placed in a cage. Every time he activated the lever a food pellet fell in the food dispenser (positive reinforcement). The rats quickly learnt to go straight to the lever after a few times of being put in the box
This suggests that positive reinforcement increases the likelihood of the behavior being repeated.

In another experiment, a rat was placed in a cage in which they were subjected to an uncomfortable electrical current (see diagram above) as he moved around the cage the rat hit the lever, this immediately switched off the electrical current (negative reinforcement365体育登录). The rats quickly learnt to go straight to the lever after a few times of being put in the box.
This suggests that negative reinforcement increases the likelihood of the behavior being repeated.
365体育登录Behaviorism has experimental support: Pavlov showed that classical conditioning leads to learning by association. Watson and Rayner showed that phobias can be learnt through classical conditioning in the “little Albert” experiment.
365体育登录It introduced the scientific methods to psychology. Laboratory experiments were used with high control of extraneous variables. These experiments were replicable and the data obtained was objective (not influenced by an individual’s judgement or opinion) and measurable. This gave psychology more credibility.
Many of the experiments carried out were done on animals; we are different cognitively and physiologically, humans have different social norms and moral values these mediate the effects of the environment therefore we might behave differently from animals so the laws and principles derived from these experiments might apply more to animals than to humans.
It has practical applications for example systematic desensitisation based on classical conditioning is used in the treatment of phobias. Classical and operant conditioning have also been used to explain attachment.
It does not explain important aspects of human behavior such as memory and problem solving as these are internal mental events which cannot be observed.
365体育登录 It does not take into account biological factors such as the role of neurotransmitters, for example a low level of serotonin can give rise to depression or high level of dopamine is involved in OCD.
It sees people as passive in their learning with little conscious thoughts influencing their behavior; other approaches recognise the importance of mental events in the learning process.
365体育登录 It neglects the influence of free will as it argues that our behavior is the result of previous conditioning. Skinner argues that free will is an illusion.
Bandura agreed with the behaviorists that behavior is learnt through experience however he proposed a different mechanism than conditioning. He argued that we learn through observation and imitation of others’ behavior.
365体育登录This theory focuses not only on the behavior itself but also on the mental processes involved in learning so it is not a pure behaviorist theory.
Mediational processes are cognitive factors that influence learning and come between stimulus and response. This includes attention, retention, motor reproduction and motivation.
Imitation is more likely to occur if the model (the person who performs the behavior) is positively reinforced. This is called vicarious reinforcement.
365体育登录 Imitation is also more likely if we identify with the model. We see them as sharing some characteristics with us i.e. similar age, gender, social status as we identify with them.
It was a lab experiment. Sample: American children, 36 boys and 36 girls aged between 3-6 years old .
Then the children were taken to a room with some attractive toys but were told not to play with the toys (aggression arousal).
Then the children were taken individually in a room containing a bobo doll, non-aggressive toys like pencils and plastic farm animals and aggressive toys like a hammer and a pistol.
The children who had observed the aggressive model (group 1) were more aggressive than the children from the other two groups. Group 1 imitated specific aggressive acts that were displayed by the model. Boys imitated more physically aggressive acts than girls. There was no difference in the verbal aggression between boys and girls.
365体育登录 This supports SLT as it shows that children imitate behavior of role model even if the behavior is aggressive.
The bobo doll experiment was repeated, but this time the three groups were exposed to an aggressive model and saw different consequences for the model:
When left on their own to play the children in group 1 showed the most aggression followed by group 3. Group 2 was the least aggressive.
This shows that imitation is more likely to occur when the model is positively reinforced, demonstrating the importance of vicarious reinforcement.
This theory is used to explain the influence of the media on behavior. This has been used in court in the case of Jamie Bulger’s murder(1990).
365体育登录 The perpetrators, who were themselves children, claimed that they had been influenced by the film Child Play 3. However these children came from a disturbed family where they might have witness real life violence and social deprivation.
365体育登录Social learning theory is supported by research Bandura at al. (1961) and Badura and Walters (1963) however these were laboratory experiments and the task did not reflect the way the participants behave in their normal life.
At this young age parents would guide their understanding of the situation and moderate their behavior this was not the case in the studies as the children were on their own. The children were aggressive towards a doll which they know does not feel pain and cannot retaliate; their behavior might be different towards another child.
Furthermore the children were in an unfamiliar environment they might have thought that they were expected to behave like the model (demand characteristics).
The participants were young children, older children and adults might not have imitated the aggressive behavior as they have more developed moral values.
The theory does not explain why the boys imitated the physical aggressive behavior more than the girls. Other factors must be involved such as biological factors like testosterone.
SLT can explain the difference of behavior between different cultures as if a behavior is not displayed it cannot be imitated, this can explain why groups such as the Amish are non-violent.
365体育登录SLT can be used to explain the influence of media on aggressive behavior.
It is a more complete explanation of human behavior than conditioning as it takes into account cognitive factors in learning. However it does not take into account free will and moral values.
365体育登录Strong determinism of the behavioral approach as all behavior is learnt from our environment through classical and operant conditioning. We are the sum total of our previous conditioning.
Softer determinism of the social learning approach theory as it recognises an element of choice as to whether we imitate a behavior or not.
365体育登录Behaviorism is very much on the nurture side of the debate as it argues that our behavior is learnt from the environment.
The social learning theory is also on the nurture side because it argues that we learn our behavior from role models in our environment.
The behaviorist approach proposes that apart from a few innate reflexes and the capacity for learning, all complex behavior is learned from the environment.
The behaviorist approach and social learning are reductionist; they isolate parts of complex behaviors to study.
365体育登录The behaviorists take the view that all behavior, no matter how complex, can be broken down into the fundamental processes of conditioning.
It is a nomothetic approach as it views all behavior governed by the same laws of conditioning.
However, it does account for individual differences and explain them in terms of difference of history of conditioning.
The behaviorist approach uses lab. experiments which are highly controlled therefore they are replicable. Furthermore, it measures observable behaviors, therefore no interpretations is required therefore the data is objective.
365体育登录However the behaviorists use animal experiments as it assumes that humans learn in the same way than animals.
The cognitive approach is focused on how our mental processes affect our behavior. It argues that internal mental processes (operations of the mind e.g. perception of memory that mediate between stimulus and response) should be studied scientifically.
Cognitive psychology365体育登录 has been influenced by developments in computer science and analogies are often made between how a computer works and how we process information.
365体育登录 Based on this computer analogy, cognitive psychology is interested in how the brain inputs, stores and retrieves information.
This has lead to models which shows information flowing through the cognitive system such as the multi-store model of memory.
The main assumption of the cognitive approach is that information received from our senses is processed by the brain and that this processing directs how we behave.
365体育登录These internal mental processes cannot be observed directly but we can infer what a person is thinking based on how they act.
Cognitive processing can often be affected by schemas (a mental framework of beliefs and expectations developed from experience). As you get older, these become more detailed and sophisticated.
A schema is a “packet of information” or cognitive framework that helps us organise and interpret information. They are based on our previous experience.
Schemas help us to interpret incoming information quickly and effectively, this prevents us from being overwhelmed by the vast amount of information we perceive in our environment.
However it can also lead to distortion of this information as we select and interpret environmental stimuli using schemas which might not be relevant. This could be the cause of inaccuracies in areas such as eyewitness testimony. It can also explain some errors we make when perceiving optical illusions.
Cognitive neuroscience is the scientific study of the influence of brain structures on mental processes, done through the use of brain scanning techniques such as fMRI.
Neuroscience aims to find out how the brain structures influence the way we process information and map mental cognitive functions to specific areas of the brain. This is done using brain imaging techniques such as fMRI and PET scans.
365体育登录 Examples of brain mapping: Braver et al. (1997) found that when their participants were performing activities involving the central executive while being scanned the prefrontal cortex showed greater activity. This suggests that the central executive is situated in the prefrontal cortex.
Laboratory experiments: These are the preferred method of investigation of the cognitive approach i.e. Loftus and Palmer (1974) - Car Crash Study365体育登录. In these experiments the extraneous variables are tightly controlled so they can be replicated, but they lack ecological validity as they take place in artificial environments and the tasks are also artificial.
365体育登录For example, in real life if you were a witness to a car crash you would not be interviewed by a psychologist but by a policeman/woman and you would know that there would be consequences to what you say so you might be more careful about the way you answer the questions. Participants could be influenced by demand characteristics.
Case studies365体育登录: These are used to study rare conditions which provide an insight on the working of some mental processes i.e. Clive Wearing, HM.
Although case studies deal with very small sample so the results cannot be generalised to the wider population as they are influenced by individual characteristics, they allow us to study cases which could not be produced experimentally because of ethical and practical reasons.
Brain imaging365体育登录: fMRI and Pet scans are used to map areas of the brain to cognitive function because the processing of information by centres in the brain to be seen directly. Such processing causes the area of the brain involved to increase metabolism and "light up" on the scan. i.e. Braver et al. (1997).
365体育登录The study of memory has lead to the development of cognitive interview which has decreased the inaccuracy of eyewitness memory; this should lead to a decrease of wrongful convictions.
It also helped us understand the causes of depression and the approach also proposes a therapy, cognitive behavioral therap365体育登录y which has shown to be effective for a range of mental disorders and unlike drugs has no side effects.
The cognitive approach uses a very scientific method; mainly lab. experiments. These are controlled and replicable so the results are reliable however they lack ecological validity because of the artificiality of the tasks and environment so it might not reflect the way people process information in their everyday life.
For example Baddeley (1966) used lists of words to find out the encoding used by LTM, however these words had no meaning to the participants so the way they used their memory in this task was probably very different than they would have done if the words had meaning for them. This is a weakness as the theories might not explain how memory really works outside the laboratory.
The cognitive approach has a wide range of practical applications. For example schemas can be used to explain how eyewitness memories of events can be distorted therefore inaccurate. The study of memory processes such as cue dependent forgetting has lead to a strategy to improve EWT: cognitive interview.
By highlighting the importance of cognitive processing, the cognitive approach is able to offer an explanation for mental disorders such as depression where Beck argues that it is the negative schemas we hold about the self, the world and the future which lead to depression rather than external events.
However it does not take into account the genetic factors which seem to be involved in mental disorders such as schizophrenia. Furthermore this approach has lead to cognitive behavioral therapy which is an effective way to deal with depression and unlike drugs has not side-effects.
The approach is reductionist as it does not take into account emotions and motivation which influence the processing of information and memory. For example according to the Yerkes-Dodson law anxiety can influence our memory.
365体育登录However the cognitive approach is less deterministic than the learning approach as although it argues that our thinking is limited by the way we process information it does not deny the influence of moral values and social norms.
The position of the approach is unclear as it argues on one hand that we the way we process information is determined by our past experience (schemas).
On the other hand in the therapy derived from the approach (CBT) it argues that we can change the way we think.
The cognitive approach takes an interactionist view of the debate as it argues that our behavior is influenced by learning and experience (nurture), but also by some of our brains’ innate capacities as information processors e.g. language acquisition (nature).
The cognitive approach tends to be reductionist as when studying a variable it isolates processes such as memory from other cognitive processes. However, in our normal life we would use many cognitive processes simultaneously, so it lacks validity.
It is nomothetic approach as it focuses on establishing theories on information processing that apply to all people.
The cognitive approach uses lab. experiments which are highly controlled therefore they are replicable. However, it measures non-observable behaviors; therefore it could be argued that it is not as scientific as the behaviorist approach.
The main assumption of the biological approach is that our thinking and behavior are strongly determined by biological factors: structure and functioning of the nervous system. This in turn is influenced by genetic and evolutionary factors.
365体育登录The influence of genes: Heredity is the passing of characteristics from one generation to the next via the genes.
Each individual possesses a unique combination of genetic instructions meaning that we differ from each other in terms of personality, intelligence and abilities etc.
365体育登录Genes code for characteristics such as eye colour but also for the structure of the nervous system and for the functioning of the nervous system i.e. neurochemistry, the amount of neurotransmitters produced and the way they are used.
To determine the involvement of genetic factors we use twin studies. We compare the concordance rate (the presence of the same trait in both members of a pair of twins) of monozygotic twins (MZ twins-same genetic material) to the concordance rate of dizygotic twins (DZ twins- share 50% of their genetic material). For example McGuffin et al. (1996) found 46% concordance for depression in MZ twins compared with 20% DZ twins.
Genotype: is the genetic code that is written in the DNA, i.e., the genetic makeup of an individual (genes present in each of your cells).
Phenotype: the physical representation that results from the individual's genotype. For example, the genetic characteristics expressed by an individual (whether they have blue eyes or brown eyes).
365体育登录 A practical example of the difference between genotype and phenotype: phenylketonuria (PKU) PKU is a genetic disorder which affects the ability to break down a substance contained in normal foods (phenylalanine).
365体育登录 If the individual follows a strict diet avoiding this substance his phenotype will be normal intelligence and behavior however if an individual eats a diet containing the substance then it will accumulate in the brain, this will lead to a different phenotype: severe learning difficulties and behavioral problem.
This shows that the presence of particular genes might lead to different outcome depending on the social environment. This shows that characteristics depend upon an interaction between nature (the genes) and nurture365体育登录 (the environment).
Charles Darwin proposed the theory of natural selection. He argued that genetically determined characteristics or behavior that enhances our chances of survival and reproduction will be passed on to the next generation, and become more common in a population whereas traits which do not enhance survival will gradually disappear.
Evolutionary psychology is an approach that attempts to explain mental and psychological traits i.e. as memory and perception as adaptations which increase our chances of survival. An example of behavior of evolutionary explanation is Bowlby’s theory of attachment.
The understanding of the role of the role of neurotransmitters has led to the development of drugs which are effective in the treatment of mental disorders such as schizophrenia and depression.
365体育登录This enables many of the sufferers to lead a fairly normal life.
However these drugs are not effective for all patients and they can have serious side effects and they do not cure the disorders as if the patients stop taking the drug the symptoms reappear.
It uses scientific research methods such as EEGs, fMRI and PET scans and twin studies. These produce objective data which can be replicated and peer reviewed.
It could be argued that twin studies do not separate nature and nature because twins are raised and live in the same environment and the difference in the concordance rate found between MZ and DZ twins could be due to the fact that MZ twins are treated more similarly by their parents than DZ twins because they look more similar.
Also we usually do not find 100% concordance rate in MZ twins for mental disorders which indicates that environmental and social factors must be involved in the development of these disorders.
365体育登录The approach has real-life applications: based on the understanding of the neurotransmitters psychoactive drugs have been developed which help treat mental disorders such as OCD and depression.
This allows people with these mental disorders to live a fairly normal life. However they do not cure the disorders and when patients stop the drugs the symptoms reappear.
365体育登录These drugs can have very serious side-effects. Additionally it could be argued that the unbalance in neurotransmitters such as low serotonin in depressed individual is the consequence rather than the cause of depression because the brain is a plastic organ which changes with the way we use it so it could be that the depressed thinking causes the low level of serotonin observed.
Furthermore the imbalance in neurotransmitters is usually not directly observed it is deduced from drug trials where patients are given the drugs and seen to improve so we deduce that it was the lack of the neurotransmitters which cause the disorder but this might not be the case.
For example if we cut ourselves and the cut becomes infected it is not the lack of disinfectant which causes the infection it is the presence of germs.
The biological approach is determinist as it sees our behavior as caused entirely by biological factors over which we have no control. This encourages people not to take responsibility for their own actions and blame their genetic makeup.
It is also reductionist as it reduces our behavior to the outcome of the actions of genes and other biological processes neglecting the effects of childhood and our social and cultural environment.
It is strongly determinist as it views our behavior as caused entirely by biological factors over which we have no control.
365体育登录The biological approach is firmly on the nature side of the debate; however, it does recognise that our brain is a plastic organ which changes with experience in our social world so it does not entirely deny the influence of nurture.
The biological approach is reductionist as it aims at explaining all behavior by the action of genetic or biochemical processes. It neglects the influence of factors such as early childhood experiences, conditioning or cognitive processes.
365体育登录It is nomothetic approach as it focuses on establishing laws and theories about the effects of physiological and biochemical processes that apply to all people.
365体育登录The biological approach uses very scientific methods such as scans, and biochemistry. Animals are often used in this approach as the approach assumes that humans are physiologically similar to animals.
The main assumption of the psychodynamic approach is that all behavior can be explained in terms of the inner conflicts of the mind.
Freud highlights the role of the unconscious mind, the structure of personality and the influence that childhood experiences365体育登录 have on later life.
Freud believed that the unconscious mind determines most of our behavior and that we are motivated by unconscious emotional drives.
According to Freud our personality is composed of three parts (tripartite):
365体育登录To be mentally healthy the ego has to be able to balance the demands of the ego and the superego. If the superego is dominant, the individual might develop a neurosis e.g. depression. If the ID is dominant, the individual might develop a psychosis e.g. schizophrenia.
The mind is divided in three parts:
When unconscious conflicts between the Id and the superego cannot be resolved by the ego they create anxiety. To reduce this anxiety we use defense mechanisms such as repression.
|Stage||Source of pleasure||Outcome|
|Oral (0-1year)||Mouth – sucking, swallowing etc.||If forceful feeding, deprivation or early weaning occur then fixation could lead to oral activities (e.g. smoking), dependency, and aggression.|
|Anal (1-3 years)||The anus – withholding or expelling faeces.||If toilet training is too harsh or too lax then fixation could lead to obsessiveness, tidiness, meanness; or to untidiness and generosity.|
|Phallic (3-5 years)||The penis or clitoris – masturbation.||If abnormal family set-up leading to unusual relationship with mother/father then fixation could lead to Vanity, self-obsession, sexual anxiety , inadequacy, Inferiority, envy,|
|Latent (5-puberty)||Sexual drives are repressed.||Fixation does not happen in this stage.|
|Genital (puberty-death)||The genitals. The adult derives pleasure from masturbation and sexual intercourse.||Fixation at this stage should occur in a mentally healthy adult.|

The psychodynamic approach has given rise to one of the first “talking cure", psychoanalysis, on which many psychological therapies are now based. Psychoanalysis is rarely used now in its original form but it is still used in a shorter version in some cases.
This approach can be used to explain mental disorders such as depression and schizophrenia although these explanations are rarely used by mainstream psychology. One of the very influential concept put forward by Freud is the lasting importance of childhood on later life and development.
365体育登录 These case studies used mainly unstructured interviews so yielded qualitative data. The need for interpretation of the material gathered means that it is biased on the part of the researchers as they tend to interpret the data in a way that supports their theory.
365体育登录 Furthermore, the fact that two different researchers can reach completely different interpretations of the same case suggests that the methods lack objectivity.
It is strongly determinist as it views our behavior as caused entirely by unconscious factors over which we have no control.
365体育登录The psychodynamic approach recognises the influence of social factors as it argues that we are driven by innate biological instincts, represented by the Id (nature), but the ways these instincts are expressed is shaped by our social and cultural environment (nurture).
365体育登录The psychodynamic approach is determinist as it rejects the idea of free will. A person’s behavior is determined by their unconscious motives which are shaped by their biological drives and their early experiences.
Freud argued that human behavior is governed by universal processes that apply to everyone e.g. the tripartite structure of the mind (nomothetic) however, he also proposed that the ways in which these processes manifest themselves in the individual is unique (idiographic).
The concepts proposed by Freud cannot be tested empirically. The theory is not falsifiable as if people behave in the way predicted by the theory it is viewed as support, if they don’t it is argued that they are using defence mechanisms.
Every person has their own unique way of perceiving and understanding the world and that the things they do only make sense in this light. Therefore, the aim of this approach is not objectivity as the other approaches; its aim is to understand people’s subjectivity.
According to this approach, people are self-determining365体育登录, which means that they have free will they can make choices about the way they think and act. These choices are not determined by biological or other external factors.
365体育登录All people have an innate tendency towards growth and the fulfilment of their potential, they have a desire to become everything that they are capable of – self-actualisation.
However, according to Maslow, people also have needs which must be met for self-actualisation to be possible. The basic needs e.g. food and water have to be satisfied before the higher.
365体育登录According to Rogers, people could only self-actualise if they had a positive view of themselves (positive self-regard). This can only happen if they have unconditional positive regard from others – if they feel that they are valued and respected without reservation by those around them (especially their parents when they were children).
However, most people don’t perceive the positive regard of others as being unconditional. They tend to think they will only be loved and valued if they meet certain conditions of worth. These conditions of worth create incongruity within the self between the real self (how the person is) and the ideal self (how they think they should be or want to be).
Self-actualisation is only possible if there is congruence between the way an individual sees themselves and their ideal self (the way they want to be or think they should be).
If there is a large gap between these two concepts, negative feelings of self-worth will arise that will make it impossible for self-actualisation to take place.
Based on this approach, client-centred therapy aims to increase clients’ self-worth and decrease the incongruence between the self-concept and the ideal self.
It is a non-directive therapy in which the client is encouraged to discover their own solutions to their difficulties in an atmosphere that is supportive and non-judgemental and that provides unconditional positive regard.
365体育登录It focuses on the present rather than dwell on the past unlike psychoanalysis. This therapy is widely used e.g. health, education and industry.
It has given rise to a new way to look at people’s needs, for example Maslow’s hierarchy of needs is widely used in health and social work as a framework for assessing clients’ needs.
365体育登录 Client-centred therapy is widely used in health, social work and industry. This therapy has helped many people overcome difficulties they face in life, which is a significant contribution to improving people’s quality of life.
365体育登录The approach uses non-scientific research methods. As its aim is to understand people’s subjectivity, it uses methods that yield qualitative data such as unstructured interviews or participant observations. These are difficult/ impossible to replicate and the interpretation of the data is influenced by researcher bias.
365体育登录It proposes a positive view of human nature, however, it could be argued that this might not be very realistic when considering the everyday reality such as domestic violence and genocides.
365体育登录 Furthermore, the approach’s focus on meeting our needs and fulfilling our growth potential reflects an individualistic, self-obsessed outlook that is part of the problem faced by our society rather than a solution.
365体育登录The approach is holistic as it does not try to break down behaviors in simpler components, e.g. Stimulus and response – Increases validity when compared to other explanations like the behaviorist approach.
The approach is non-determinist as it recognises free will but its position on this topic is somewhat incoherent as on one hand it argues that people have free will but, on the other hand it argues that our behavior is determined by the way other people treat us (whether we feel that we are valued and respected without reservation by those around us).
The approach recognises both the influence of nature and nurture, nurture- the influence of experiences on a person’s ways of perceiving and understanding the world, nature- influence of biological drives and needs (Maslow’s hierarchy of needs).
Cultural bias – Personal growth would be associated with individualist cultures as collectivist cultures such as India emphasise community and interdependence – The approach is a product of the cultural context within which it was developed and an emic approach is more appropriate.
It is the only approach that explicitly states that people have free will, but its position on this topic is somewhat incoherent as on one hand it argues that people have free will but, on the other hand it argues that our behavior is determined by the way other people treat us (whether we feel that we are valued and respected without reservation by those around us).
The approach recognises both the influence of nature and nurture, nurture- the influence of experiences on a person’s ways of perceiving and understanding the world, nature- influence of biological drives and needs (Maslow’s hierarchy of needs).
365体育登录The approach is holistic as it does not try to break down behaviors in simpler components.
As this approach views the individual as unique it does not attempt to establish universal laws about the causes of behavior, it is an idiographic approach.
365体育登录As the approach views the individual as unique it does not believe that scientific measurements of their behavior are appropriate.
