Approaches Flashcards
Define psychology
- the scientific study of the mind and behaviour
Define science
- the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence
Which philosophers have contributed to the emergence of psychology
- Rena Descartes
- John Locke
- Charles Darwin
Who is Wilhem Wundt
- “father of psychology”
- first person to call himself a psychologist
- ideas stemmed from philosophical roots
- opened first experimental psychological lab which helped shape psychology as a science
- wanted to focus on the psychological processes of perception and structuralism
Give details about the lab opened by Wilhem Wundt
- opened in 1879
- Leipzig, Germany
- designated to aid the scientific study of psychological inquiry using controlled conditions that could facilitate the replication of results
- Wundt devised introspection as a way of studying internal mental events
What is 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
What is the psychological process of structuralism
- theory of consciousness developed by Wundt
- involves use of introspection, self reports of sensations/views/feelings/emotions
- he wanted to document and describe the structure of human consciousness (introspection)
How was structuralism tested
- involved Wundt and his workers recording their conscious thoughts and breaking them down into their constituent parts
- he wanted to investigate psychology the same as traditional sciences
- used scientific methods to investigate introspection
- paved way for psychology to be seen as a science and develop cognitive psychology
How was introspection tested
- strictly controlled conditions in lab using same stimuli, same reaction times and same instructions
- individuals focused on present experiences
- involves person saying everything in their mind while doing activity
- must keep talking even if ideas are not clear
- must not hesitate => can use fragmented sentences and do not have to justify thoughts
- made research into introspection reliable so it could be replicated
- made psychology different from philosophical roots
- later realised mental processes difficult to study using introspection and encouraged a search for alternative methods
Who questioned the emergence of psychology as a science
- Watson (1913)
- Skinner (1953)
How did Watson (1913) question the emergence of psychology as a science
- argued process of introspection produced subject data
- varied person to person
- made it difficult to establish general principles
- proposed a truly scientific psych should restrict itself only to studying phenomena that could be observed and measured
- thus behaviourist approach was born
How did Skinner (1953) question the emergence of psychology as a science
- brought methods of natural sciences into psych
- behaviour approach => controlled lab experiments
- following cognitive revolution, study of mental processes seen as scientific through inferences
- biological approach also makes use of experimental data => researchers take advantage of recent advances in tech to investigate physiological processes as they happen
- even though the scientific method is still to be fully embedded in psych, it has come a long way
What is the timeline of psychology emerging as its own subject
- 17-19th century, psychology is a branch of philosophy known as experimental philosophy
- 1879, Wundt opens lab
- 1900s, Freud introduced psychodynamic approach
- 1913, Watson and Skinner establish behaviourist approach
- 1950s, Rogers and Maslow establish humanistic approach
- 1960s, cognitive approach reintroduced, SLT proposed by Bandura
- 1980s, biological approach
What are positive evaluation points for introspection
- helped develop other approached in psych (behaviourism/cognitive), very useful phenomena used in psych that based formed basis of other approaches
- scientific sharing same qualities as traditional sciences such as making hypotheses, high level of control of variables as conducted in lab
- causality can be established allowing future behaviour to be predicted
- still used today in areas of therapy showing application to contemporary therapy used in modern society
- Wundt supports reductionism, consciousness could be broken down to basic elements without sacrificing any of the properties of the whole
What are negative evaluation points for introspection
- Watson (1913) criticised introspection, it produces subjective data varying from individual to individual meaning it is not objective nor reliable
- not scientific or accurate, Wilson claims psychologists have little knowledge about some behaviour that may exist outside of conscious awareness
- fails to explain how the mind works and the processes involved in thinking about a particular topic, psychologists cannot see how thoughts are generated so cannot be properly observed
What are the different approaches
- behaviourist approach
- learning approach
- cognitive approach
- biological approach
- psychodynamic approach
- humanistic approach
How is the behaviourist approach split
- classical conditioning
- operant conditioning
What are key assumptions of the behaviourist approach
- concerned with observable behaviour that can be objectively and scientifically measured
- all behaviour is learned from environment and can be reduced to stimulus-response association
- little difference between learning that takes place in humans and non human animals allowing research to be carried out on animals as well as humans
What is classical conditioning
- all behaviour is learnt rather than being innate or inherited
- learning through association
- stimulus produces same response as another stimulus because they have been consistently presented at the same time
What are examples of classical conditioning
- Pavlov (1927) => salivating dogs
- Watson and Rayner (1928) => little Albert
What was Pavlov (1927)
- investigated salivating reflex in dogs
- noticed dogs would not only salivate when food was placed in their mouths but also when certain stimuli appeared
- e.g. dog bowl or person who usually feeds them
- he explored how dogs had learnt that these stimuli meant food was on the way
- decided to see if he could teach dogs to salivate when he rang a bell
What happened before conditioning for Pavlov (1927)
- food was unconditioned stimulus producing reflex of salivating which is an unconditioned response
- bell was a neutral stimulus producing no conditioned response
What happened during conditioning for Pavlov (1927)
- the unconditioned stimulus of food was repeatedly paired with the neutral stimulus of the bell
- eventually the dog associated the bell with food
What happened after conditioning for Pavlov (1927)
- bell was a conditioned stimulus producing salivating in the dogs as a conditioned response
What is an unconditioned stimulus in classical conditioning
- any stimulus that elicits a natural response and does not have to be learned
What is an unconditioned response in classical conditioning
- any natural response that does not require learning
What is an neutral stimulus in classical conditioning
- any stimulus that does not elicit a response
What is an conditioned stimulus in classical conditioning
- a stimulus which was previously neutral but was constantly paired with an unconditioned stimulus
What is an conditioned response in classical conditioning
- when an unconditioned response is paired with a neutral response and then the neutral stimulus elicits a conditioned response
What are positive evaluation points for classical conditioning
- research support in being able to explain development of learning and phobias, evidence comes from Little Albert by Watson and Rayner => successful in explaining how learning can occur in animals and young children
- Pavlov’s research has helped apply classical conditioning to treatments of psychological disorders, e.g. flooding and SD which are based on components of classical conditioning
What are negative evaluation points for classical conditioning
- validity
- generalisation
- Menzies
- deterministic
How is validity a negative evaluation point for classical conditioning
- must be cautious when using findings from Little Albert and Pavlov’s study
- conducted in lab setting
- different results may be gained from different setting
- lack ecological validity
How is generalisation a negative evaluation point for classical conditioning
- may not be strong in explaining how adults learn new behaviours
- limited to only explaining learning in young children and animals as shown in Watson and Rayner’s and Pavlov’s research
How is Menzies a negative evaluation point for classical conditioning
- criticises behavioural model
- studies people with hydrophobia
- found only 2% of sample encouraged negative experience with water
- therefore 98% of sample had phobia of water but never had a negative experience involving water
- means they had not learnt to be frightened of water
How is determinism a negative evaluation point for classical conditioning
- classical conditioning viewed as deterministic as it ignores role of free will in people’s behavioural responses
- anticipates an individual will respond to a conditioned stimulus with no variation
- people are not passive states and they do have some control over how they might respond to an association between two stimuli
What is operant conditioning
- organisms spontaneously produce different behaviours
- behaviours produce consequences for organism
- some consequences may be positive and some negative
- if consequence of behaviour is positive then likely behaviour is repeated
- if consequence of behaviour is negative then likely behaviour is not repeated
How is operant conditioning different to classical conditioning
- responses are reinforced in operant conditioning but not in classical conditioning
- classical conditioning explains acquisition of a response while operant explains the maintenance of a response
What is reinforcement
- something in the environment that strengthens a particular behaviour
- two types: positive and negative
What is positive reinforcement
- occurs when behaviour produces a consequence that is satisfying or pleasant for the organism
What is negative reinforcement
- occurs when behaviour removes something aversive and returns the organism to the pre aversive state
What is primary and secondary reinforcement
- primary reinforcement is reinforcement meeting natural needs such as food to take away hunger or water to take away thirst
- secondary reinforcement is reinforcement meeting all needs such as money
- types of positive reinforcement
What is punishment
- occurs when a behaviour leads to an unpleasant consequence
- decreases likelihood that the behaviour will occur again
- two types: positive and negative punishment
What is positive punishment
- when something unpleasant is added to a person’s life that was not there before
What is negative punishment
- when something pleasant is removed from a person’s life
Who investigated operant conditioning
- Skinner (1953)
- conducted a study on rats in a decide called the Skinner Box
- Skinner Box was a cage which has loud speakers, lights, a level, a door and a floor which could be electrified
What happened in Skinner (1953)
- one hungry rat at a time placed in Skinner box and allowed to freely run around
- rat might accidentally press lever and be rewarded by a food pellet which would drop into the Skinner box (positive reinforcement)
- rat then continues to press level in order to receive a food pellet in future, as rat soon learned pressing lever led to reward
- rat could also learn pressing lever could avoid something unpleasant
- by pressing levers rat could avoid receiving electric shock (negative reinforcement)
What are schedules of reinforcement
- means there are different methods of reinforcement that might occur, e.g.
- continuous reinforcement => every time rat presses lever they always receive food pellet
- fixed interval => the rat pressed the lever and only receives a food pellet during a fixed interval only
- fixed ratio => the rat must press the lever for a fixed number of times and then it receives the pellet
What are positive evaluation points for operant conditioning
- Paul and Lentz
- experimental method
- nature/nurture
How is Paul and Lentz a positive evaluation point for operant conditioning
- practical applications
- token economy used in institutions as a form of behaviour modification
- token economies work by rewarding appropriate behaviour with tokens which can be exchanged for privileges
- research by Paul and Lentz used a token economy to treat patients with SZ
- found their behaviour became more appropriate
How is experimental method a positive evaluation point for operant conditioning
- Skinner box relied on experimental method
- highly controlled conditions to discover relationship between variables
- cause and effect relationship could be established
How is nature/nurture a positive evaluation point for operant conditioning
- nurture side
- states learning occurs due to environmental factors and external stimuli rather than biology
- therefore by manipulating factors in the environment, this can have an effect on learning and behaviour and is supported by nurture
What are negative evaluation points for operant conditioning
- determinism
- ethics
- biological approach
How is determinism a negative evaluation point for operant conditioning
- Skinner ignores concept of free will
- suggests past experiences will affect future behaviour
- people/animals have no control over their actions or the behaviours they show
- deterministic view which does not account for free will
How is ethics a negative evaluation point for operant conditioning
- rats and pigeons often placed in Skinner box in stressful and aversive conditions
- could have a negative effect on the psychological and physical health of the animals
- issue of generalising results from animals to humans
- animals are very physiologically different to humans so results may not be applicable to humans
How is biological approach a negative evaluation point for operant conditioning
- ignores biological approach
- biological approach would argue against behaviour approach
- would state behaviour cannot be learnt but instead it heavily influenced by the role of genes/hormones/biochemical and neural mechanisms
- therefore other approaches must be considered when examining the influences upon behaviour
- operant conditioning cannot explain all behaviour, e.g. do people learn to be aggressive
What are positive evaluation points for the behaviourist approach
- scientific
- principles
- real life applications
How is scientific a positive evaluation point for the behaviourist approach
- behaviourism was able to bring language and methods of natural sciences in psych
- done by focussing on the measurement of observable behaviour within highly controlled lab settings
- by focussing on importance of scientific processes (objectivity, replications), behaviourism was influential in the development of psych as a scientific discipline
How is principles a positive evaluation point for the behaviourist approach
- behaviourist approach developed laws and principles
- enabled psychologists to predict and control behaviour
- however, it raises ethical concerns
- the approach could be used to control people against their wishes
How are practical applications a positive evaluation point for the behaviourist approach
- principles of conditioning have been applied to a broad range of real world behaviours and problems
- e.g. SD and flooding from classical conditioning for treating psychological disorders and phobias
- e.g. token economy from operant conditioning for improving behaviours of SZ patients
What are negative evaluation points for the behaviourist approach
- mechanistic
- reductionist
- deterministic
- ethics
- generalisation
How is mechanistic a negative evaluation point for the behaviourist approach
- from a behaviourist perspective, animals and humans are seen as passive and machine like responders to the environment
- can learn new behaviours unquestionably and have little conscious thought
- minimises free will
- other approaches (cognitive) emphasise importance of mental events during learning
- therefore behavioural approach may apply less to humans than animal behaviour
How is reductionist a negative evaluation point for the behaviourist approach
- environmentally reductionist
- focuses on a lower level of explanation than other approaches
- stimulus-response associations lack meaning when attempting to explain complex human behaviours
- e.g. attachment
How is deterministic a negative evaluation point for the behaviourist approach
- environmentally deterministic
- sees all behaviour as determined by past experiences that have been conditioned
- Skinner suggested everything we do is the suit total of our reinforcement history
- ignores idea of free will which may also influence behaviour
How is ethics a negative evaluation point for the behaviourist approach
- although experimental procedures enabled behaviourists to maintain a high degree of control over subjects, manny critics questioned ethics of conducting such investigation
- animals involved were exposed to stressful and aversive conditions
- may have affected how they reacted to the experimental situation
How is generalisation a negative evaluation point for the behaviourist approach
- uses non human animals for research
- critics claim this tells us little about human behaviour because humans have cognitive factors and emotional states that influence their behaviour
- means findings cannot be extrapolated and applied to humans
What is the social learning theory
- new patterns of behaviour can be acquired/learnt though observing the behaviour of others
- during learning, people perform behaviours and observe different consequences
- e.g. punishment or reinforcement
- behaviour is learnt from the environment and also considers cognitive processes
What are the assumptions of social learning theory
- behaviour is learned through experience
- specifically through observation and imitation within a social context
Who proposed social learning theory
- Bandura (1977)
What were the points proposed by Bandura (1977) for SLT
- modelling
- imitation
- identification
- vicarious reinforcement
- meditational processes
What is modelling in SLT
- social learning requires a person to model or carry out the behaviour
- allows observer to learn the behaviour
- model can be live (parent, teacher, peer) or symbolic (TV character)
- models provide examples of behaviour which can be learned by imitation
What is imitation in SLT
- children learn behaviours via imitation
- modelled by significant others
- tends to be faster than classical or operant conditioning
- key characteristics of successful imitation include
=> characteristics of the model (age, gender)
=> the observers perceived ability to perform the behaviour shown
=> the observed consequence of behaviour (positive or negative)
What is identification in SLT
- extent to which the observer relates to the model // feels they are similar to them
- so they could experience same outcomes as model
- person would aim to be like the models as much as they could
- children likely to identify with model of same sex as themselves in order for social learning to be effective
What is vicarious reinforcement in SLT
- individuals learn by observing the behaviour of others and the reward/punishment they receive
- people do not need to experience rewards/punishments directly to learn
- may learn behaviours but not perform because they have learnt the behaviour leads to punishment if displayed
What are mediational processes in SLT
- social learning places importance on internal cognitive mediational processes
- observer must form a mental representation of behaviour displayed by model and likely consequences of behaviour in terms of expectancies
- observer might display learned behaviour, provided there is the expectation that positive consequences are more likely to occur than negative
- 4 points
What are the different points of mediational processes in SLT
- attention => observer must pay attention and notice the behaviour of the mode
- retention => observer must remember behaviour of model
- motor reproduction => observer must be able to perform the behaviour
- motivation => observer must be willing to perform the behaviour in light of rewards
Who carried out research into SLT
- Bandura (1961)
- BOBO doll experiment
What was the sample for Bandura (1961) and how were they split into groups
- 72 children ages 3-7
- 36 boys 36 girls
- 3 groups
=> model behaving aggressively towards BOBO doll
=> model not behaving aggressively
=> control group where there was no model
What was the procedure for Bandura (1961) into SLT
- children split into groups and watched video of model unless in control group
- aggressive model displayed distinctive aggressive acts towards doll => strike with mallet and verbal aggression “POW”
- children then taken to a room with toys one by one but told they cannot play to induce mild frustration
- children then taken to a room one by one with toys including a BOBO doll (mallet, dart gun and other non aggressive toys as well) and were told they could play => observed for 20 minutes
What were the findings for Bandura (1961) into SLT
- children who observed aggressive model reproduced same behaviour towards BOBO doll
- children who observed non aggressive model showed no aggression to BOBO doll
- 33% of aggressive group repeated verbal aggression heard “POW”
- 0% of child in non aggressive group displayed verbal aggression
- in a follow up study, children observed a model being rewarded for aggressive behaviour
=> increased likelihood children are aggressive (vicarious reinforcement) - boys more likely to be aggressive than girls, and imitation of aggression highest when model was same gender
What was the conclusion for Bandura (1961) into SLT
- aggression can be learned through social learning such as meditational processes, observation, modelling, identification and vicarious reinforcement
