Approaches in Psychology Flashcards
Outline the role of Wundt in the origins of psychology
- The first psychology lab was opened in Leipzig, Germany
- Aim of psychology was to describe the “nature of human consciousness” in a carefully controlled, scientific environment
Define introspection
The first systematic experimental attempt to study the mind
Outline the role of standardised procedures in the origins of psychology
- The same standardised instructions were given to all participants and stimuli (objects or sounds) were presented in the same order
- For example, participants were given a ticking metronome and they would report their thoughts, images and sensations, which were then recorded
Define structuralism
- Introspection led to identifying the structure of consciousness by breaking it up into the basic structures : thoughts, images and sensations
- This marked the beginning of SCIENTIFIC PSYCHOLOGY, separating it from its broader philosophical roots
What were the early behaviourists’ (e.g. Watson) views on introspection and psychology (1900s)
- Rejected introspection
- Watson argued introspection was SUBJECTIVE because it’s influenced by a personal perspective
- According to the behaviourist approach, “scientific” psychology should only study phenomena that can be observed and measured
Outline how the behaviourist approach (1930s) dominated psychology for 50 years
- Skinner brought the language of the natural sciences into psychology
- The behaviourists focussed on learning, and the use of carefully controlled lab studies, which would dominate psychology for 50 years
Outline how the cognitive approach (1950s) viewed psychology following the computer revolution
- Cognitive approach studied mental processes scientifically
- Following the computer revolution of the 1950s, the study of mental processes was seen as legitimate within psychology
- The mind was likened to a computer and psychologists tested predictions about memory and attention using experiments
Outline how the biological approach (1980s) viewed psychology after introducing technological advances, e.g. fMRI
Biological psychologists have taken advantage of recent advances in technology, including recording brain activity by using scanning techniques, e.g. fMRI, EEG and using advanced genetic research
Aspects of Wundt’s work are scientific. How is this a strength of the emergence of psychology as a science?
- He recorded the introspections within the controlled lab environment
- He also standardised his procedures so that all participants received the same information and were tested in the same way
- Therefore, Wundt’s research can be considered a forerunner to the later scientific approaches
Aspects of Wundt’s work are subjective. How is this a weakness of the emergence of psychology as a science?
- Wundt relied on participants self-reporting their “private” mental processes. Such data is subjective, as participants may have hidden some of their thoughts
- This makes it difficult to establish meaningful “laws of behaviour”, one of the aims of science
- Therefore, Wundt’s early efforts to study the mind were naïve and would not meet the criteria of scientific enquiry
Wundt made a significant contribution to psychology. How is this a strength of the emergence of psychology as a science?
- Wundt produced the first academic psychology journal and wrote the first psychology textbook
- He is often referred to as “the father of psychology”
- His pioneering research set the foundation for approaches that were to come, particularly the behaviourist and cognitive approaches
- This shows that, despite the flaws in his early experimental research, Wundt made a significant contribution to psychology
Research in modern psychology can claim to be scientific. How is this a strength of the emergence of psychology as a science?
- Psychology has the same aims as the natural sciences - to describe, understand, predict and control behaviour
- Learning, cognitive and biological approaches all use scientific methods, e.g. lab studies are controlled are unbiased
- Throughout the 20th century and beyond, psychology has established itself as a scientific discipline
Some approaches use subjective data. How is this a weakness of the emergence of psychology as a science?
- Humanistic approach doesn’t formulate general laws of behaviour
- Psychodynamic approach uses case studies with unrepresentative samples
- Psychologists study humans who are active participants and therefore respond to demand characteristics
- Therefore, a scientific approach to the study of human thought and experience is not desirable or possible
Psychology does not have a clear paradigm, and therefore may not class as a science. How is this a weakness of the emergence of psychology as a science?
- Kuhn said that any science must have a paradigm - a set of principles, assumptions and methods that all people who work within that subject agree on
- Psychology does not have a paradigm, HOWEVER, most would agree it’s the study of mind and behaviour
- This suggests that the question of whether psychology is a science remains unanswered
Outline the key features of the behaviourist approach
- Only focusses on observable and measurable behaviour - rejected introspection because of its vague and immeasurable concepts
- Controlled lab studies - tried to maintain control and objectivity in their research
- Used non-human animals as test subjects - behaviourists suggest the learning processes are the same in all species, so animals can replace human as test subjects
Outline classical conditioning through the use of Pavlov’s dogs
Outline operant conditioning through Skinner’s research with rats
- Behaviour is shaped and maintained by its consequences
- When a rat activated a lever, it was rewarded with a food pellet
- A positive consequence led to a behaviour being repeated (POSITIVE REINFORCEMENT)
- If pressing a lever meant the rat would avoid an electric shock, the behaviour would also be repeated (NEGATIVE REINFORCEMENT)
Describe the 3 consequences of behaviour
- POSITIVE REINFORCEMENT - receiving a reward when behaviour is performed
- NEGATIVE REINFORCEMENT - avoiding something unpleasant when behaviour is performed
- PUNISHMENT - an unpleasant consequence of behaviour
Positive and negative reinforcement increase the likelihood that behaviour will be repeated. Punishment decreases it
Behaviourism uses well-controlled research. How is this a strength of the behaviourist approach?
- This approach has focussed on the careful measurement of observable behaviour within controlled lab settings
- Behaviourists have broken behaviour down into “stimulus - response” units and studied causal relationships
- This suggests that behaviourist experiments have scientific credibility
The behaviourist approach may oversimplify learning. How is this a weakness?
- It may ignore important influences on behaviour, (e.g. thought) and sees the mind as a BLACK BOX
- Other approaches, e.g. SLT and cognitive include mental processes
- This suggests learning is more complex than just what we observe
The behaviourist laws of learning have real world application. How is this a strength of the behaviourist approach?
- The principles of conditioning have been applied to a broad range of real world behaviours and problems
- TOKEN ECONOMY SYSTEMS reward appropriate behaviour with tokens that are exchanged for privileges (operant conditioning). Successfully used in prisons and psychiatric wards
- This increases the value of the behaviourist approach because it has widespread application
Behaviourism is a form of environmental determinism. How is this a weakness of the behaviourist approach?
- The approach sees all behaviour as determined by past experiences that have been conditioned and ignores any influence that free will may have on behaviour
- Skinner suggested that free will was an illusion. When something happens, we may think “I made the decision to do that”, but our past conditioning determined the outcome
- This is an extreme position and ignores the influence of conscious decision making processes on behaviour (as suggested by the cognitive approach)
How are ethical issues regarding the Skinner box study a weakness of the behaviourist approach?
- Procedures such as the Skinner box allowed behaviourists to maintain a high degree of control over their experimental “subjects”
- HOWEVER, the animals were housed in harsh, cramped conditions and deliberately kept below their natural weight so they were always hungry
- Therefore, there is a question of benefits vs costs - some would argue that there have been enormous benefits (e.g. application the therapy) which offsets the harm the animals experienced
Outline the key features of Social Learning Theory (SLT)
- Learning that occurs indirectly - Bandura agreed with the behaviourist approach that learning occurs through experience. HOWEVER, he also proposed that learning occurs in a social context through observation and imitation of others’ behaviour
- Vicarious reinforcement - children and adults observe people’s behaviour and take note of its consequences. Behaviour that is seen to be rewarded is more likely to be copied
- Mediational processes - play a crucial role in learning
- Identification with role models - people are likely to imitate the behaviour of those with whom they identify. Such role models are similar to the observer, attractive and have high status
Outline the 4 mediational processes in Social Learning Theory (ARMM)
- ATTENTION - whether behaviour is noticed
- RETENTION - whether behaviour is remembered
- MOTOR REPRODUCTION - being able to do it
- MOTIVATION - the will to perform the behaviour
Outline Bandura’s 1961 Bobo dolls study
- Children watched either :
- An adult behaving AGGRESSIVELY towards a Bobo doll
- An adult behaving NON-AGGRESSIVELY towards a Bobo doll
- When given their own doll to play with, the children who had seen aggression were much more aggressive towards their doll
Outline Bandura and Walters’ 1963 Bobo dolls study
- Children saw videos of an adult who was aggressive towards Bobo dolls and was either :
- REWARDED
- PUNISHED
- THERE WAS NO CONSEQUENCE
- When given their own doll, the children who saw the aggression rewarded were much more aggressive themselves, even weeks later
What were the conclusions of the Bobo dolls studies?
- Children are likely to imitate acts of violence if they observe these in an adult role model (MORE LIKELY IF ADULT WAS THE SAME GENDER AS THEM)
- Modelling aggressive behaviour is more likely if such behaviour is seen to be rewarded (VICARIOUS REINFORCEMENT)
SLT emphasises the importance of cognitive factors. How is this a strength of Social Learning Theory?
- Neither classical or operant conditioning can offer a comprehensive account of human learning on their own because cognitive factors are omitted
- Humans and animals store information about the behaviour of others and use this to make judgements about when it is appropriate to perform certain behaviours
- This suggests that SLT provides a more complete explanation of human learning than the behaviourist approach by recognising the role of MEDIATIONAL PROCESSES
According to recent research, SLT makes little effort to reference the biological factors involved in learning. How is this a weakness of SLT?
- Recent research suggests that observational learning is controlled by mirror neurons in the brain
- This allows us to empathise with and imitate other people
- This suggests that SLT may make too little effort to reference the influence of biological factors on social learning
SLT relies too heavily on evidence from lab studies. How is this a weakness of Social Learning Theory?
- Many of Bandura’s ideas were developed through observation of children’s behaviour in lab settings and this raises the problem of DEMAND CHARACTERISTICS
- The main purpose of a Bobo doll is to hit it. So the children in those studies may have been behaving as they thought was expected
- Aggression was operationalised by seeing HOW the children hit the doll, e.g. punching, pounding, etc.
- Thus, the research may tell us little about how children actually learn about aggression in everyday life
SLT has real world applications. How is this a strength of Social Learning Theory?
- Social learning principles can account for how children learn from other people around them, as well as through the media, and this can explain how cultural norms are transmitted
- This has proved useful in understanding a range of behaviours, e.g. how children come to understanding their gender roles by imitating role models in the media
- This increases the value of SLT as it can account for real world behaviour
How is reciprocal determinism a strength of Social Learning Theory?
- Bandura emphasised reciprocal determinism - we are influenced by our environment, but we also exert an influence upon it through the behaviours we choose to perform
- This element of choice suggests there is some free will in the way we behave (e.g. choosing our friends)
- This is a more realistic and flexible position than is suggested by the behaviourist approach as it recognises the role we play in shaping our own environment
Outline the emergence of cognitive neuroscience in the cognitive approach
- Scientific study of the influence of brain structures on mental processes
- With advances in brain scanning technology, scientists have been able to describe the neurological basis of mental processing
- This includes research in memory that has linked episodic and semantic memories to opposite sides of the prefrontal cortex
- Scanning techniques have also proved useful in establishing the neurological basis of some disorders, e.g. parahippocampal gyrus → OCD
Outline how computer models to explain mental processes in the cognitive approach
- Computer models refer to programmes that can be run on a computer to imitate the human mind (e.g. conversational machines to deal with consumer enquiries)
- By running such a programme, psychologists can test their ideas about information processing
Outline how theoretical models to explain mental processes in the cognitive approach
Information flows through a sequence of stages that include input, storage and retrieval, as in the multi-store model
Describe the 4 different types of schema in the cognitive approach
- Role schema - proper behaviours in given situations - expectations about people in particular positions, e.g. teachers, doctors, etc.
- Self schema - about ourself : idealised and possible
- Person schema - expectations about personality traits
- Event schema - SCRIPTS : what happens in certain situations
Scientific and objective methods are used in the cognitive approach. How is this a strength?
- Cognitive psychologists have always employed controlled and rigorous methods of study, e.g. lab studies in order to infer cognitive processes at work
- In addition, the fields of biology and cognitive psychology came together (COGNITIVE NEUROSCIENCE) to enhance the scientific basis of study
- This means that the study of the mind has established a credible, scientific basis
Research on cognitive processes may lack external validity. How is this a weakness of the cognitive approach?
- The use of inference means cognitive psychology can occasionally be too abstract and theoretical
- Research often uses artificial stimuli (e.g. word lists)
- Therefore, research of cognitive processes may lack external validity and not represent everyday experience
The cognitive approach has application to everyday life. How is this a strength?
- The cognitive approach is dominant in psychology today and has been applied to a wide range of practical and theoretical contexts
- For instance, AI and the development of the robots, the treatment of depression and improving EWT
- This supports the value of the cognitive approach
The cognitive approach is based on machine reductionism. How is this a weakness?
- Although there are similarities between the operations of the human mind and computers (e.g. inputs→outputs, central processor, storage systems), the computer analogy has been criticised
- Emotion and motivation have been shown to influence accuracy of recall in eyewitness accounts. These factors are not considered within the computer analogy
- This suggests that machine reductionism may weaken the validity of the cognitive approach
How is soft determinism a strength of the cognitive approach?
- The cognitive approach recognises that our cognitive system operates within certain limits, but we are free to make decisions before responding to a stimulus
- This is in contrast to the behaviourist approach which suggests we are passive “slaves” to the environmnt and lack free choice in our behaviour - no room for human agency
- This suggests that the cognitive approach takes a more flexible middle ground position and is more in line with our subjective sense of free will
