INTRODUCTION

For centuries, philosophers and biologists theorised about the causes of human behaviour. However, Psychology as a separate academic discipline did not emerge until 1879 when Wundt established the first Psychology laboratory using a method known as introspection – reflecting on one’s own mental processes such as emotions and sensations.

Freud developed the psychoanalytic/psychodynamic approach from approx. 1895 onwards. Freud was incredibly influential on 20^th C. Psychology arguing that humans were governed by instincts and irrational unconscious conflicts which arose in early childhood experience. However, Freud’s emphasis on unobservable aspects of human behaviour (e.g. the unconscious mind) attracted criticism from psychologists who argued that Psychology should be scientific in aims and methods, and focus on observable behaviour.

The Behaviourist approach (or Learning Theory) was developed by Watson who argued that Psychology should adopt a strictly scientific, empirical approach (i.e. only focus on outwardly observable, measurable behaviour). Throughout the 20^th C. Behaviourism explored the variety of way in which behaviours are acquired (learnt), maintained (kept) and extinguished (unlearnt) via classical conditioning, operant conditioning and social learning.

By the 1950’s Cognitive psychologists returned to studying internal mental processes (such as memory, perception, attention, decision-making, etc.) and the development of the first computers in the ‘50’s allowed Cognitive psychologists to model human mental processes artificially (e.g. chess computers). The Cognitive approach also favoured scientific methods and controlled experimentation.

The Biological approach has always existed within Psychology, focusing on the way in which internal structures and processes (the brain, neurotransmitters, hormones, genes, etc.) influence the mind and behaviour. Biological psychology employs highly scientific methods and shares much in common with biology and chemistry.

Humanistic Psychology emerged in the 1960’s and was critical of Behaviourist and Psychodynamic arguments that behaviour was controlled by the either the environment or the unconscious mind. Humanistic psychologists argued that people had free-will (can actively choose how they want to act, feel and behave) and the potential to guide their own personal growth to achieve psychological health, overcome traumas in their past and achieve self-actualisation (personal fulfilment and happiness).

ORIGINS OF PSYCHOLOGY: WUNDT, INTROSPECTION AND THE EMERGENCE OF PSYCHOLOGY AS A SCIENCE (AQA A-level Psychology resources)

For centuries, philosophers and biologists theorised about the causes of human behaviour, however Psychology as a separate academic discipline did not emerge until 1879 when Wundt established the first Psychology laboratory in Germany. Wundt employed introspection as his main method – asking subjects to systematically report on their inner mental processes such as emotions and sensations, and asking them to describe the quality, duration and intensity of what they felt.

Wundt used experimental methods to try to establish the basic building blocks (structures) of thought and investigate how they interacted with each other. Thus, he attempted to break down participants’ observations of objects, images and events down into constituent parts in the same way that an anatomist would study a body by trying to find its constituent parts (e.g. heart, liver, etc.) and how they interact.

For example, in studying reaction time, Wundt systematically changing the stimuli he presented to participants and measured how long it took them to respond - inferring that the longer it took them to respond the more mental processes must be involved.

One major criticism of Wundt’s approach relates to the methodology of introspection. Critics argue that relying on individuals' self-reporting of their thoughts and feelings is subjective: i.e. depends on individual perception and interpretation. Variability in individuals' introspective reports, the inability to access certain mental processes consciously, and the potential influence of biases all undermine the reliability of introspection as a method of inquiry.

Wundt's structuralism, with its emphasis on breaking down mental processes into isolated elements, has also been criticised for oversimplifying the complexity of human cognition and emotion. Critics argue that the reductionist nature of this approach neglects the holistic and dynamic nature of human consciousness and fails to capture how various mental processes interact and influence each other in real-world scenarios.

Lastly, Wundt's work lacked the cross-cultural perspective that contemporary psychology recognises as crucial. His studies were primarily conducted on Western, middle-class populations, which limits the generalisability of his findings to non-European populations.

LEARNING APPROACHES (BEHAVIOURISM) (A-level Psychology notes)

THE BEHAVIOURIST APPROACH, INCLUDING CLASSICAL CONDITIONING AND PAVLOV’S RESEARCH, OPERANT CONDITIONING, TYPES OF REINFORCEMENT AND SKINNER’S RESEARCH; SOCIAL LEARNING THEORY INCLUDING IMITATION, IDENTIFICATION, MODELLING, VICARIOUS REINFORCEMENT, THE ROLE OF MEDIATIONAL PROCESSES AND BANDURA’S RESEARCH

 From the 1920’s-60’s Behaviourism attempted to develop a more scientific approach in Psychology focusing on observable behaviour and how individuals acquire/learn behaviours through interaction with their social environment: e.g. family, peers, teachers.

CLASSICAL CONDITIONING AND PAVLOV’S RESEARCH

Classical Conditioning (CC) argues that behaviours are acquired through ‘stimulus-response’ associations: e.g. an event in the environment (stimulus) will cause a physiological effect (response) such as fear, happiness, etc. If this association is repeated a number of times the response will automatically occur every time the stimulus is presented.

 

In 1927 Pavlov formulated the basics of CC after studying why dogs in his laboratory salivated in the presence of his research assistants.

Dogs naturally salivated in the presence of food. He described this link as an unconditioned stimulus (UCS - the food) causing an unconditioned response (salivation - UCR).

By repeatedly pairing the UCS of food with a neutral stimulus (a bell ringing) just before presentation of food, Pavlov found that eventually dogs salivated simply at the sound of the bell. Therefore, the neutral stimulus of the bell had become a conditioned stimulus (CS) producing a conditioned response (CR) of salivation.

RELATIONSHIP TO OTHER SYLLABUS AREAS

• Watson later showed how phobias could be acquired through CC in the ‘Little Albert’ experiment. (Psychopathology)
• Systematic Desensitisation is based on the principles of CC to ‘unlearn’ phobic responses. (Psychopathology)
• Learning Theory of attachment partly explains attachment through CC. (Attachment)

This material could be described and evaluated in an Approaches question on CC to provide practical applications/explanations from this approach.

OPERANT CONDITIONING, TYPES OF REINFORCEMENT AND SKINNER’S RESEARCH

Operant Conditioning (OC) focuses on how behaviour is influenced by the consequences of our actions.

If behaviours are reinforced (rewarded) then they are strengthened and more likely to be repeated in the future. If behaviours are punished (or ignored) they will be less likely to be repeated in the future and may eventually be extinguished. For example, aggressive behaviours in a child could be strengthened through the positive reinforcers of praise, attention, respect, etc.

Skinner (‘53) developed a ‘Skinner Box’ to study leaning through OC in rats and pigeons. An animal placed in the box would discover accidentally at some point that pressing a lever in the box would release a food pellet. This positive reinforcement would increase the frequency of lever-pressing. This would also occur if the lever took away an unpleasant stimulus such as a loud noise – i.e. negative reinforcement. Unsurprisingly, punishments such as the lever generating an electric shock would lead to decreased lever-pressing.

 

REINFORCEMENT (REWARD) (Good thing!) PUNISHMENT   (Bad thing!) POSITIVE   Receive something pleasant: food, pleasure,  praise, attention, approval, respect, love, sympathy, etc. Receive something unpleasant: pain, disapproval, nausea, disrespect, etc. NEGATIVE Removal of something unpleasant: e.g. early release from jail for good behaviour. Removal of something pleasant: fines, taking away freedom, material possessions, etc.

 RELATIONSHIP TO OTHER SYLLABUS AREAS

• Learning Theory of attachment partly explains attachment through OC. (Attachment)

This material could be described and evaluated in an Approaches question on OC to provide practical applications/explanations from this approach

SOCIAL LEARNING THEORY (SLT) INCLUDING IMITATION, IDENTIFICATION, MODELLING, VICARIOUS REINFORCEMENT, THE ROLE OF MEDIATIONAL PROCESSES AND BANDURA’S RESEARCH

SLT was developed by Bandura in the 60’s and focuses on how behaviours such as aggression may be learnt via observation and imitation of others.

• Modelling: imitating observed behaviour (e.g. aggression) of a model.
• Vicarious Learning: imitation as a result of seeing another individual being positively reinforced (e.g. praise, popularity, respect, etc.) for a behaviour (e.g. aggression).

Imitation is most likely if the learner (e.g. a boy) identifies with the person whom they are imitating – the model (e.g. the boy’s father, a media hero, a peer, etc.)

Bandura identified 4 mediational processes in social learning.

Mediational processes refer to the thoughts/cognitions which influence whether we will or will not imitate others and how motivated we are to do so.

• Attention: the observer must observe the model behaving in a particular way.
• Retention: the observer must remember what they’ve seen.
• Reproduction: the observer must be capable of imitating the observed act.
• Motivation: the observer must be willing to imitate the observed act.

A study into imitative aggression based on SLT

Bandura (61) divided 72 children aged 4 into 3 groups of 12 boys and 12 girls.

• In condition 1 the children saw a male and a female adult model physically and verbally attack a 5’ tall inflatable doll (bobo doll).
• In the 2^nd condition the adults did not aggress against the doll.
• In condition 3 there was no adult model at all.

Children were then taken to a room and prevented from playing with some attractive toys (to frustrate them).

They were then taken to a 3^rd room with a bobo doll and various weapons. Bandura’s observation of imitative aggression found that children in condition 1 who had witnessed the violent model were far more likely to aggress against the bobo doll than those in the other conditions.

Bandura’s research implies that violence in the media and the family can cause imitative aggression in children.

RELATIONSHIP TO OTHER SYLLABUS AREAS

• Bandura’s study is described in more details in the Aggression
• SLT is discussed in the Gender

This material could be described and evaluated in an Approaches question on SLT to provide practical applications/explanations from this approach

EVALUATION OF LEARNING APPROACHES

STRENGTHS

• Behaviourism adopts a strictly empirical approach: i.e. it only focuses on observable behaviour which can be measured and tested – it does not make reference to hypothetical, non-measurable or observable states such as ‘the super-ego, ‘emotion’, ‘motivation’, etc. Equally, Behaviourism employs scientific methods – experiments conducted under tightly controlled laboratory conditions aimed at understanding the cause-effect relationships which govern the acquisition, maintenance or extinction of behaviours.
• Behaviourism illustrates how our social environment – family, peers, teachers, etc. – influences our behaviour through reinforcement, punishment or imitation. Clearly this is an important ‘nurture’ influence governing a huge range of behaviours ranging from gender role to aggression to language acquisition. Therefore, Behaviourism is important in understanding how our social experiences with others in the family, our peer group, at school, at work, etc. mould our behavioural responses.
• Learning theory has been used to develop methods for controlling behaviour in real-world situations: for example, classroom and family discipline, managing the behaviour of prisoners or inmates in mental institutions, and treating mental disorders such as phobias (SD).

WEAKNESSES

• Behaviourists argued that humans are born a ‘tabula rasa’ (blank slate) whose behaviour, personality and attitudes are acquired as a result of learning. Behaviourism is criticised for its extreme ‘nurture’ viewpoint: e.g. it argues that all behaviours are acquired through learning and ignores the importance of biology, instinct, evolution and thought (cognition) in influencing behaviour. Thus, Behaviourism is reductionist (reduces all behaviour to learning) and deterministic (argues that our behaviours are determined by previous learning experiences and we possess no free-will or choice).
• The laws of Behaviourism were originally formulated using research conducted on animals such as rats, dogs and pigeons. Behaviourists believed that the fundamental laws governing the acquisition of behaviours were similar for all species including humans. Clearly, there is a problem of generalising from animals to humans in regard to the complexity of human cognitive processes. Although animals may respond fairly mechanically to conditioning, human cognitions make human behavioural responses much more complex.
• You can also gain marks for evaluation by stating what Learning Theory ignores which other approaches do take account of.

THE COGNITIVE APPROACH (AQA A-level Psychology notes)

THE STUDY OF INTERNAL MENTAL PROCESSES, THE ROLE OF SCHEMA, THE USE OF THEORETICAL AND COMPUTER MODELS TO EXPLAIN AND MAKE INFERENCES ABOUT MENTAL PROCESSES. THE EMERGENCE OF COGNITIVE NEUROSCIENCE

Cognitive (from the Latin cogito – I think) refers to the study of human mental processes.

Cognitive Psychology developed from the 1950’s onwards partly as an improvement on Behavioural Psychology which failed to recognise the importance of mental processes in determining behaviour; partly, as a result of the development of computers which were able to mimic human mental processes.

THE STUDY OF INTERNAL MENTAL PROCESSES

Cognitive Psychology is concerned with internal mental processes such as

• Perception – how we take in and make sense of external environmental stimuli.
• Attention – how we focus in on and filter out external environmental stimuli.
• Memory – how we retain and recall information.
• Language – the use of mental symbols to represent, manipulate and communicate aspects of internal and external reality.
• Thinking – judgement, reasoning, logic, problem-solving.

Thus Cognitive Psychology is concerned with all the ways in which knowledge of the world is attained, retained and used.

THE ROLE OF SCHEMA

Schemas are mental maps of understanding about the world, ourselves and others: for example, we have schemas of understanding about how to use the Underground, how to act in a job interview, how a policeman is likely to behave, etc. Our schemas help us make sense of, understand and predict what is likely to happen in situations. In the field of eye-witness testimony (EWT) schemas about race, gender and social class have been shown to bias witness’s memories of events in that stereotypes may cause us to believe that some people are more likely to commit crime.

THE USE OF THEORETICAL AND COMPUTER MODELS TO EXPLAIN AND MAKE INFERENCES ABOUT MENTAL PROCESSES

The mind is often conceptualised as a computer/information processor. The mind has an input of information from the external world via the senses; throughput in the form of memory, thinking and language; and output in the form of decision-making, speech and action.

Parallel processing is processing different tasks at once (e.g. driving a car and holding a conversation). Sequential processing is performing one task and then another, in order.

The brain can be conceptualized as ‘hardware’, our experiences and learnt responses as ‘software’.

Cognitive abilities such as memory and attention have limited capacities and if concentration/focus on one task is interfered with by competing stimuli we may lose focus/be distracted. For example, when learning to drive we may find that holding a conversation is causing interference meaning that we lose focus and driving ability suffers.

Inference refers to going beyond the immediate evidence to make assumptions about mental processes that cannot be directly observed. Much memory research makes inferences about the underlying processes of memory by drawing inferences from studies which involve, for example, asking participants to recall lists of words.

RELATIONSHIP TO OTHER SYLLABUS AREAS

• Memory: the whole topic is based on the Cognitive Approach.
• Psychopathology: the cognitive approach to understanding and treating depression focuses on cognitions (thoughts).
• Gender: Kohlberg’s theory and Gender Schema Theory are based on children’s changing cognitions about gender

This material could be described and evaluated in an Approaches question on the Cognitive Approach to provide practical applications/explanations from this approach

EVALUATION OF COGNITIVE APPROACH

STRENGTHS

• The cognitive approach has been useful in researching, describing and understanding the effects of mental processes and cognitions on behaviour: e.g. Loftus and Palmer’s study of eyewitness testimony showed that memory can be warped and distorted after the event by leading questions. Studies such as these have real-life applications – in this case how witnesses are questioned by police and cross-examined by lawyers. Similarly, cognitive therapies are widely employed in the NHS and research evidence indicates they are an effective in the treatment of a wide range of disorders – depression, stress, anxiety, social phobias, etc.
• The cognitive approach lends itself to laboratory experimentation, therefore hypotheses can be tested under highly controlled conditions, confounding variables can be eliminated, and cause-effect relationships between variables established. The testing of mental processes such as memory or perception often makes use of technical measuring instruments which ensures high levels of precision in measurements taken.

WEAKNESSES

• Although the computer analogy of the mind is, in some respects, suitable, computers essential number-crunch quantitative data at high speeds. Humans are far less capable than computers in this respect, but computers do not possess most of the characteristics of the human mind – intuitive decision-making, emotion, personal beliefs and motivations, self-consciousness, moral judgment, etc. Thus humans are qualitatively different to computers. Even the most advanced computer technology is far from able to mimic more complex human mental states.
• The cognitive approach views thought processes as all important in determining emotional state and behaviour. It ignores, therefore, alternative influences on behaviour such as instinct, genetics, neurotransmitters, learning experiences and social environment. For example, a depressive’s maladaptive cognitions could be the result of a biochemical imbalance, and mood and behaviour could be improved by a drug such as Prozac rather than through altering cognitions.
• You can also gain marks for evaluation by stating what the Cognitive Approach ignores which other approaches do take account of. 

THE EMERGENCE OF COGNITIVE NEUROSCIENCE

Cognitive neuroscience brings together knowledge of the structure and functions of the brain (from Biological Psychology) with cognitive psychologists’ knowledge of mental processes such as memory and perception. By studying individuals who have suffered damage to the brain, brain scanning techniques can illustrate which parts of the brain are involved with which mental processes. For example, HM had his hippocampus removed in an operation to reduce his epilepsy. After the operation he could remember things he had just been told suggesting that his STM was intact, but he could not transfer this information to the LTM. Thus he could not form new long-term memories. He could, however, remember things (LTM) from before the surgery. This provides evidence for the MSM’s argument that STM and LTM are 2 separate stores.

THE BIOLOGICAL APPROACH (A-level Psychology revision notes)

THE INFLUENCE OF GENES, BIOLOGICAL STRUCTURES AND NEUROCHEMISTRY ON BEHAVIOUR. GENOTYPE AND PHENOTYPE, GENETIC BASIS OF BEHAVIOUR, EVOLUTION AND BEHAVIOUR

EVOLUTION AND BEHAVIOUR

Darwin’s theory of evolution argues that physical and psychological characteristics which increase the chances of an organism surviving and reproducing (adaptive traits) mean that these characteristics will be more likely to be passed onto the next generation. For example, during the evolution of homo sapiens (approx. 150,000 – present) traits such as physical strength and intelligence would lead individuals to being more likely to survive (by gaining resources: e.g. hunting and gathering food) and reproduce, thus passing on these characteristics genetically to the next generation. Traits such as physical beauty in humans or length and quality of plumage in a peacock are indicators of ‘good’ genes and health: characteristics which are attractive to potential mates.

GENOTYPE AND PHENOTYPE

Adaptive traits which brought advantages to our ancestors are coded in our genes. At the point of conception 2 sets of chromosomes (23 from the father and 23 from the mother) combine to form the unique combination of 46 genes present in each individual. The term genotype refers to the unique combination of genes present in the DNA of every cell in an individual’s body.

From conception, genes interact with the environment in various ways – first of all within the mother’s body: for example, toxins such as alcohol may be passed through the placenta, then from the outside world: for example, exercising will make one stronger. The way in which the genotype is modified and influenced by the environment is referred to as the phenotype.

THE INFLUENCE OF GENES ON BEHAVIOUR

Twin studies can be used to assess to what extent psychological characteristics are genetically inherited (nature) or caused by the environment (nurture). Schizophrenia, intelligence and personality type are some of the characteristics which evidence suggests are partially genetically determined. By studying large numbers of identical (MZ) and non-identical (DZ) twins where 1 of the twin pair has a characteristic (such as schizophrenia) we can calculate a ‘concordance rate’ – the average % probability that the other twin will also possess that characteristic. If the concordance rate is higher for MZ’s (who share 100% genetic similarity) than DZ’s (who are only 50% alike) we can deduce that the disorder is genetic to some extent. For example, concordance rates for depression are about 46% of MZs and only 20% for DZs.

THE INFLUENCE OF NEUROCHEMISTRY ON BEHAVIOUR

It is believed that inherited genes which cause mental disorders operate by causing abnormal neurotransmitter levels.

Excessive levels of the neurotransmitter dopamine are associated with schizophrenia. Phenothiazines (drugs used to treat schizophrenia) inhibit dopamine activity and reduce symptoms, and L-Dopa (used to treat Parkinson’s disease) stimulates dopamine production and produces schizophrenic symptoms in unaffected individuals.

The Relationship between Dopamine, Phenothiazines & L-Dopa

DISORDER	SYMPTOMS	DRUG USED TO TREAT	EFFECT OF DRUG	SIDE EFFECTS OF DRUG
Schizophrenia	Delusions, hallucinations	Phenothiazines	Lowers dopamine- reduces delusions and hallucinations	Stiffness of limbs
Parkinson’s Disease	Stiffness of limbs	L-Dopa	Increases dopamine - reduces stiffness of limbs	Delusions and hallucinations

THE INFLUENCE OF BIOLOGICAL STRUCTURES ON BEHAVIOUR

The link between brain structures and their functions is referred to as brain localisation.

Brain localisation can be studied via

• Invasive methods

Animals can have brain sites electrically or chemically stimulated, or cut/burnt out (lesions). Psychologists then monitor the animal for changes in behaviour.

• Non-invasive methods

Brain scans such as CAT, PET and MRI scans use a variety of techniques to ‘see’ inside live brains. By asking people taking scans to perform certain tasks and monitoring electrical activity and blood flow we have been able to build up a picture of brain localisation.

For example, HM had his hippocampus removed in an operation to reduce his epilepsy. After the operation he could remember things he had just been told suggesting that his STM was intact, but he could not transfer this information to the LTM. Thus he could not form new long-term memories. He could, however, remember things (LTM) from before the surgery. This provides evidence for the MSM’s argument that STM and LTM are 2 separate stores.

RELATIONSHIP TO OTHER SYLLABUS AREAS

• Biological explanations and treatments for Schizophrenia (Schizophrenia) or OCD (Psychopathology)
• Biological explanations of gender role (Gender)
• Neural and hormonal mechanisms in aggression (Aggression)

This material could be described and evaluated in an Approaches question on the Biological Approach to provide practical applications/explanations from this approach.

EVALUATION OF THE BIOLOGICAL APPROACH

STRENGTHS

• The biological approach employs scientific methods such as laboratory experiments on physiological structures and processes conducted under controlled conditions. These produce quantitative data which can be statistically analysed to show cause-effect relationships between variables. For example, experimentation have proven that schizophrenia is linked to high levels of the neurotransmitter dopamine. The drug chlorpromazine blocks dopamine receptors, reduces dopamine levels and lessen the disorder’s symptoms. Thus, scientific experimentation allows us to determine cause-effect relations between biological and psychological factors.
• Findings have resulted in practical applications which reduce suffering. For example, chemotherapy - the use of drugs to treat mental disorders - improves the quality of life of the mental ill. Before the invention of drug therapies, there was little that could be done to help schizophrenics; chlorpromazine reduces the severity of symptoms and helps schizophrenics live independently and take care of their own basic needs. Anti-depressants may improve the mood of depressives to motivate them to engage in therapy and become more sociable.

WEAKNESSES

• The biological approach is determinist – all behaviours are believed to be biological in origin – the influence of ‘nurture’ factors is ignored. For example, biological psychologists focus on the role of genetic and neurological factors in understanding intelligence and under-estimate the role of social and environmental factors or past experience: e.g. intelligence is affected by family values and schooling. Thus, the biological approach oversimplifies human psychology.
• The biological approach is reductionist – it reduces the complexity of human consciousness and behaviour to biological ‘parts’ and ignores the role of cognition (thoughts). For example, the biological approach reduces mental disorders such as depression or schizophrenia to genetic and neurological causation and ignores the role that an individual’s thoughts about their self, others and their life may contribute to the onset of a disorder.
• Much experimental research conducted by biological psychologists is based on animal research. For example, Selye’s research into how bodies respond to stress was based on the stress responses of rats. Apart from the obvious physical differences, the human stress response is influenced by complex sets of cognitions (thoughts) about the stressor whereas animals generally respond to stress in a fairly predictable manner. Thus, findings from animal studies are not directly generalisable to humans.
• You can also gain marks for evaluation by stating what the Biological Approach ignores which other approaches do take account of.
