5.1 - Approaches In Psychology Flashcards
What is psychology?
The scientific study of the human mind and its function, especially those functions affecting behaviour in a given context
What is science?
A means of acquiring knowledge through systematic and objective investigation. The aim is to discover general laws
Define introspection
The first systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations
Who was Wundt and what did he do?
• he is known as the father of psychology
• opened the first institute for experimental psychology in Germany in 1879
• separated psychology from philosophy and focused on studying the mind
• took a reductionist approach
• simplified everything down to cause and effect
What was Wundts objective?
To document and describe the nature of human consciousness
Outline introspection and problems with it
• is a psychological method to analyse someone’s thoughts and feelings internally
• this was done as there were no brain scans and computers at the time
• they used this technique of presenting a stimuli and asking how they felt after seeing it
• does not explain how the mind works it simply relies on peoples subjective thoughts
• doesn’t provide data that can be used with certain reliability
What are the 5 factors that need to be considered when deciding whether psychology is a science?
- objectivity
- control
- predictability
- hypothesis testing
- replication
What was psychology originally considered to be in the 17th-19th century?
A branch of philosophy - called ‘experimental’ philosophy
What approach did Sigmund Freud establish in the 1900s?
What therapy did he develop for depression?
-The psychodynamic approach- emphasising the influence of the unconscious mind on behaviour - also focused on the importance of early childhood experiences on shaping our personality as adults
- he also developed his on therapy for depression called psychoanalysis
What approach did J.B Watson establish In 1913?
-The behaviourist approach- believing all behaviour is learnt and that psychology should focus on studying outwardly observable behaviours rather than internal processes
- they criticised Freud and Wundt
- also influenced by B.Skinner , Pavlov and Rayner
What approach did C. Rodger’s and A.Maslow develop in the 1950s?
-The humanistic approach - highlighting free will and self- determination
- highlighting the impact of the individual themselves
What approach was established in the 1960s with the help of computers?
The cognitive approach - the belief that the human brain processes information in a way explainable by science
- the computer is used as a metaphor for the human mind
What theory did Bandura propose In the 1960s?
The social learning theory - recognises ideas of behaviourism but also highlights the need to focus on the influence of cognitive processes and learning from others behaviour
- crucially bridges the behaviourist approach with the cognitive approach
What approach did the development f technology give rise to in the 1980s?
The biological approach - our understanding of the functioning of the brain increases
Eg. MRI scans
What area of science develops from the 2000s onward?
Cognitive neuroscience
This brings together the cognitive and the biological approach
What was the focus of Wundts lab I’m Germany?
Wundts lab focused on understanding the psychological processes of perception and consciousness under controlled scientific conditions
What was different about Wundts lab compared with to previous psychological studies?
Wundts lab conducted experiments under SCIENTIFIC conditions - moving away from the experimental philosophy - psychology emerged as its own science
What was Wundts method for carrying out introspection?
Structuralism - using basic methods to find the basic structures or thought
How did Wundts lab carry out structuralism ? What did Wundt find ?
A stimulus ( eg. Metronome ) would be given and highly trained assistants would record their thoughts and feelings
The longer it took for someone to respond = more mental processes there were going om
What are the flaws of Wundts method?
1) relied on non- observable
2) Data produced is subjective and perhaps untruthful - social desirable answers
3) Sub - conscious thoughts can’t be recorded
What do these flaws do to the validity of Wundts introspection method ?
The validity is reduced as the data from the participants might not be accurate
How Does introspection benefit psychologists today?
Introspection allow psychologists of today to look for patterns of thinking attributed to a particular condition or problem
What did Wundts introspection method lay the foundations for today?
Therapies such as CBT ( cognitive behavioural therapy ) - used for treating depression and addiction
Outline introspection and the problems with it
Introspection is a psychological method to analyse someone’s thoughts and feelings internally - this was done as there were no brain scans or computers at the time so thus they used this technique of presenting a stimuli and asking how they felt after seeing it
- does not explain how the mind works
- relies on peoples subjective thoughts
- doesn’t provide data that can be used with certain reliability
What is reductionism ?
The idea that things can be reduced to simple cause and effect processes
What are the 5 features that make something a science?
1) objectivity
2) control
3) predictability
4) hypothesis testing
5) replication
What is meant by objectivity?
Scientific observations should be recorded without bias and not influences by any other factors or any other people
What is meant by control?
Scientific observations should take place under controlled conditions
What is meant by predictability?
Scientists should be able to use the results and knowledge gained from experiments to predict future behaviour
What is meant by hypothesis testing?
Theories generate predictions which can be tested to either strengthen the support for the theory, or else disprove it
What is meant by replication?
Each experiment should be able to be replicated exactly so people can have confidence in the results
What are the strengths of the scientific approach in psychology?
- due to its reliance on OBJECTIVITY and scientific methods knowledge acquired is more than just the passive acceptance of facts
- scientific methods believe in DETERMINISM they are able to establish the causes of behaviour through the use of methods that are replicable
- If Scientific methods no longer fit the facts then they can easily be refined or abandoned meaning that scientific knowledge is self corrective
- Allport (1947) said psychology has the same aims as science - to predict, understand and control
What are the limitations to a scientific approach in psychology ?
- by focusing on objectivity and control in experiments they tend to be too unrealistic and we lack an insight into natural behaviour
- a lot of psychological behaviour is unobservable and thus cannot be measured with much accuracy meaning that the gap between actual data and theories put forward is quite large
- not all psychologists believe that human behaviour can be viewed scientifically as it is not subject to laws and regularities that science implies
- unreliable methods - eg. Interview techniques which can be biased and interpreted differently by different researchers
- very hard to get representative sample of the population for a study - findings cannot be generalised
- psychological experiments are open to extraneous variables such as demand characteristics
What is behaviourism also known as?
Learning theory
The first worldwide accepted approach was behaviourism, outline this
- Behaviourism also known as learning theory started in the early 1900s by John Watson
- he believed that psychological research before this wasn’t scientific enough
What are the 3 assumptions behaviourism makes?
1) Nearly all behaviour is learnt
- only exceptions are a few inborn reflexes (eg. Blinking when we get dirt in our eyes ) + a few inborn instincts ( eg. Instinctively running when in some types of danger )
2) animals and humans learn in the same ways
- principal we learn are the same - based on the idea that we can form stimulus - response associations between stimuli and our actions
3) the mind is ‘irrelevant’
- can’t directly observe and measure a persons thinking
- can only obtain measurable data by studying behaviour
- cognitive abilities cannot be directly , scientifically measured
What 2 types of conditioning did behaviourists propose?
1) classical conditioning
2) operant conditioning
Outline pavlov’s classical conditioning
- was studying salivation however during his studies he found that dogs would end up salivating before there was any food
- direction of his studies changed and outlined classical conditioning
- when Pavlov gave his dogs food = also ring a bell
- after repeating this procedure several times - Pavlov tried ringing the bell without giving the dogs any food
- the bell alone caused salivation
- when dogs see food = they salivate - an automatic unlearned response - a reflex
- the food is an unconditioned stimulus ( UCS ) and salivation is an Unconditioned response ( UCR )
- bell had become a conditioned stimulus ( CS) - salivation has became a conditioned response ( CR )
What happens before conditioning?
A certain stimulus eg. Food —> Triggers a natural reflex eg. Salivation
( unconditioned stimulus) ( unconditioned response )
What happens during conditioning?
UCS repeatedly presented with —> salivation ( UCR )
another stimulus eg. A bell
( neutral stimulus)
What happens after conditioning?
Overtime the bell presented by itself —> salivation ( conditioned response )
( Conditioned stimulus )
What are the examples of this process being applied to human development ?
- comfort for the baby is an UCS that produces happiness the UCR
- the babies mother will talk to it while she feeds it and changes it’s nappies etc. and thus the baby hears its mothers voice every time it is made happy
- sound of the mothers voice is matched with the UCS and thus becomes a CS
- eventually the sound of the mothers voice alone will make the baby happy
- the CS now causes the CR
Outline the several principles of classical conditioning
generalisation - when stimuli similar to the original CS ( eg. A bell with a different pitch ) produce the CR (eg. Salivating )
Discrimination- when stimuli similar to the original CS don’t produce CR - can be achieved by withholding the UCS (eg.food) when the similar stimulus is used
Extinction - when the CR (eg. Salivating) isn’t produced as a result of the CS (eg. A bell )
- this happens when the CS is presenter again after a period of time during which it’s not been used
Spontaneous recovery - when a previously extinct CR is produced in response to the CS - this happens when the CS is presented again after a period of time during which its not been used
Higher order conditioning - when a new CS (eg. A light ) produces the CR because the animal associates it with the original CS
- achieved by consistently presenting the new CS before the original CS
What are standardised instructions ?
The instructions given to each participant are kept identical - to prevent experiment bias
Define genotype
An organisms genetic makeup or allele combinations
Define phenotype
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
What did skinner state in regards to operant conditioning ?
Assumes that behaviour is based on learning through consequence
Define positive reinforcement
Behaving in a way that gets rewarded - when something desirable is obtained in response to doing something eg. Giving a chocolate bar to a well behaved child to encourage future good behaviour
Define negative reinforcement
When something undesirable is removed when something happens
Eg. Being told by the teacher that you’ll have no extra homework if you pass your test
Define punishment
Behaviour is less likely to occur because of negative consequences
Define unconditioned stimulus
A stimulus that unconditionally , naturally and automatically triggers a response
Define unconditioned response
The unlearned naturally occurring response to the unconditioned stimulus such as salivation when food is in the mouth
Define neutral stimulus
A stimulus that elicits no response before conditioning
Define conditioned stimulus
A stimulus that elicits a response only after learning has taken place
Define conditioned response
A reaction that resembles an unconditioned response but is produced by a conditioned stimulus
Explain skinners (1938) rats showing operant conditioning experiment
- skinner created a Skinner box in which he placed one rat at a time
- Each skinner bod contained a variety of different stimuli eg. A speaker , lights , a floor which gave an electric shock and a food dispenser which released food when a lever was pressed
- a hungry rat was placed in the Skinner box
- the time taken for the rats to learn that pressing the lever would release food was recorded
What was the aim of skinners experiment ?
To demonstrate the principle of learning via operant conditioning
What were the results of skinners experiment ?
- initially the rat would run around the cage until it accidentally pressed the lever and it was rewarded with food
- the more the rat was put back into the box the quicker they got a learning where the lever was
What was the conclusion of skinners experiment ?
- Rats can learn behaviour through operant conditioning
- a behaviour such as pressing a lever can be positively reinforced by receiving food
Evaluate skinners experiment
- experiment used animals - ethical issues
- used animals so results may not be generalised to humans
- his sample size was small - reducing the reliability of his results
- hugely influential in promoting the idea of behavioural psychology
What are some weaknesses of conditioning ?
- experiments involved animals - cannot be generalised to humans
- different species have different capacities for learning by conditioning
- some may learn by simple observation - no reinforcement involved
- genetics influence and limit what different species can learn by conditioning
- unethical to use animals
What did skinner discover in his variation of negative reinforcement ?
- repeated the study but instead of giving food he made a loud noise which could be stopped by pressing the button
- he found that the button was pressed more often
What occurred in the punishment variation of skinners experiment ?
- He gave a shock very time he pressed the button
- this reduced the button pressing
Define habituation
An organisms decreasing response to a stimulus with repeated exposure to it
What is higher order conditioning ?
- procedure In which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus
- creating a second conditioned stimulus
What is operant behaviour ?
Behaviour that operates on the environment producing consequences
What is Thorndikes law of effect ?
The principle that behaviours followed by favourable consequences become more likely and that behaviours followed by unfavourable consequences become less likely
Define intrinsic motivation
A desire to perform a behaviour effectively for its own sake , excessive rewards undermine this
Define extrinsic motivation
A desire to perform a behaviour to receive promised rewards or avoid threatened punishment
What is the main idea of the behaviourist approach ?
- They record behaviour that can be observed and measured
- they rely on lab experiments
- reject introspection as it’s too vague
According to Pavlov what is classical conditioning ?
Learning through association
What is operant conditioning ?
Learning through consequences
Define reinforcement
A consequence of behaviour that increase the likelihood of that behaviour being repeated
Can be positive or negative
Define social learning theory
A way of explaining behaviour that includes direct and indirect reinforcement as well as other factors combining learning theory with the role of cognitive factors
What did Albert Bandura say about how people learn ?
People learn through imitation and observation of others within a social context
Define vicarious reinforcement
Observing someone less being reinforced for a behaviour directly or indirectly
Give an example of vicarious reinforcement
Banduras research :
- the children saw the adults being praised for hitting the BOBO doll and this led to more imitation
- this supper how children learn through vicarious reinforcement
- they see someone else being rewarded sp they copy the action In hope of being rewarded themselves
Define meditational processes
Cognitive factors that Influence learning and come between stimulus and response
What are the 4 meditational processes ?
- Attention - noticing behaviour
- Retention - remembering behaviour
- Motor reproduction - preforming
- Motivation - will to preform
Attention and retention = learning
Motor reproduction and motivation = performance
Define identification
When an observer associates themselves with a role model and wants to be like the role model
What is modelling in SLT ?
The person becomes a role model when they have similar characteristics to the observer and who are attractive or have a high status
What was Bandurs procedure to investigate social learning theory
( BOBO DOLL )
- recorded the behaviour of children who watched a video of an adult act aggressively towards a BOBO doll
- the children were then left to play with various toys among them a BOBO doll
- the children then started acting aggressively towards the BOBO doll
What type of theory is social learning theory ?
Reductionist - explains things through very basic cause and effect mechanisms
For eg. Explains all behaviours as a result of learning from others and ignores any biological explanations
What were the variations of Banduras BOBO doll study ?
Group 1 - children saw the adult being praised for aggressive behaviour ( vicarious reinforcement )
Group 2 - children saw the adult punished for their behaviour
Group 3 - children saw aggression with no consequence
What is the conclusion of Banduras experiment ?
Aggressive behaviour is learned through imitation of others behaving aggressively
How many children took kart in the experiment ?
36 boys and 36 girls
What is meant by ‘ the study had matched participants design ‘
Children were matched on ratings of aggressively behaviour shown at their nursery school
What 3 conditions took place in Banduras experiment ?
First condition - children observed aggressive adult models playing with the Bobo doll eg. Hitting it with a mallet
Second condition - children observed non aggressive models playing with toys and ignoring the Bobo doll
Third condition - control condition in which children didn’t have any exposure to the models
The children’s behaviour was then observed for 20 minutes in a room containing aggressive toys and non aggressive toys
Evaluate Banduras experiment
- provides evidence for social learning theory
- strict control of variables = results are likely to be reliable and the study can be replicated
- low ecological validity as the participants weren’t in a natural situation
- difficult to generalise the results because a limited sample was studied
- the children were all from the same school
- ethical problem - study promoted aggression in children
What are some extra evaluation points ?
- Banduras study shows that reinforcement is not needed for learning - we can learn by just observing
- Bobo dolls are designed for aggressive play - you’re supposed to hit them
- the children were shown how to play with the doll so this study might actually be a test of obedience rather than observational learning
- behaviourism and SLT emphasises learning as the cuss of behaviour and so are on the nurture side of the nature-nurture debate = this has implications for society - eg. Children may imitate aggression from media role models - potential genetic influences are not taken into account
- can be difficult to conclude that observational learning has taken place
What does cognitive psychology look at ?
How we interpret the world
- at the internal workings of the mind and the explains behaviour through cognitive processes
- how we think
What 4 things do cognitive psychologists look at to try and explain our behaviour ?
- perception
- language
- attention
- memory
What is the cognitive approach ?
The cognitive approach is in direct contract to the behaviourist approach, in that it argues that internal mental processes can and should be studied scientifically
What are the 4 assumptions of the cognitive approach ?
- internal mental processes should be studied to understand behaviour
- the way that humans process information can be studied scientifically
- theoretical models are a useful way of explaining mental processes
- mental processes can’t be observed so psychologists have to make logical conclusions
What are the two theoretical models which represent the internal mental processes ?
- the information processing model
- the computer model
What are the three main research methods cognitive psychologists use ?
- Laboratory experiments
- Field experiments
- Natural experiments
