Approaches Flashcards
Wundt A01
-Known as the father of psychology moved from philosophical roots to controlled research
-Set up the first psychology lab in Liepzig, Germany in the 1870’s
-promoted the use of introspection as a way of studying mental processes
-His work later paved way for the later controlled research and the study of mental processes e.g. by cognititve psychologists
Define introspection
The systematic analysis of ones own conscious experience, thought processes, feelings, emotions and sensations.
Method of introspection
- Record own conscious thoughts, breaking them down into components (structuralism)
- components are elements like sensation, emotional reactions etc * ppl were trained to do this analysis to make the data objective rather than subjective
- people were presented with standardised sensory events like a ticking metronome and asked to report their reactions.
-controlled lab setting
Who criticised introspection for not being objective?why?
Waton. subjective as it vaired from person to person, difficult to establish general principles. Truly scientific psych should resrict itself to being empirical by studying phenomena that can be observed, from this principle stemmed the behaviourist approach.
What are the features of a science?(FORE)
F-falsifiability: when its possible to prove a statement, theory or hypothesis wrong. Only possible if study is replicable
O-objectivity: free from bias, based on observable phenomena. Not influenced by personal opinion, prejudice or emotion; its empirically available for other scientists to check and verify
R-replicability: extent to which a study can be repeated so that reliabilty of results can be judged
E-empirical: directly observable and gathered through the senses. Can be verified by measurements and doesn’t go beyond the boundaries of what can be observed.
Other than FORE, what else are features of science?
1)Theory constuction and hypothesis testing: to make scientific progress it must be possible to test and falsify a theory must be Rigid and hypothesis must be clear (operationalised). Theory can be tested and proven correct or incorrect (falsified)
2)Paradigms and paradigm shifts
What is a paradigm?
a distinct set of concept or thought patterns within a specific domain. Each approach has its own paradigm.
What is a paradigm shift?
happens when a theory is falsified and a new paradigm is created that is based on the newly discovered info.
Evaluation of Wundts method and the scientific approach
(-)method is not scientific. non-empirical and subjective. Unobservable (memory, perceptions). Replication, results weren’t reliably reproduced by other psychologists.
(+)some aspects still considered scientfific. introspection recorded in controlled labs, standardised procedures, same info + tested same way. Wundts research considered forerunner to the later scientific approaches in psych.
(-)Low ecological. psyhologists particularly humnistic concentrating purely on objective and controlled methods doesn’t reveal alot about behaviour in natural setting. Most effective method is to use a range of methods to investigate aim/hyp so gather reliable and valid data to test a theory (triangulation)
(+)introspection still used. Hunter et al (2003) used as a way of making happiness a measurable phenomena. Demonstrates how introspection can be used with scientific methods to provide a greater understanding of human behaviour. Demonstrated long-lasting influence Wundt has had on the discipline of psych.
What does the learning approach focus on?
how we are all a product of our experiences (learning). and incorporates both behaviourism and SLT. All human behaviour is learnt, and we are born as ‘blank slates’
What are the basic assumptions of the behaviourist approach?
-behaviour learnt from experiences born as blank slate no genetic infuence on behaviour
-only observable behaviours is measurable scientifically and only these should be studied as thought processes are subjective and difficult to test
-should use lab experiment best way maintaining objectivity
-learning is same in all species. valid to study behaviour of animals
Behaviourist approach: classical conditioning AO1
learning by association. Humans & animals can be classically conditioned. Learning occurs when an association is made between a previously neutral stimulus and reflex response (positive or negative). Positive response will arise when the person becomes in contact with positive stimulus. Same for negative.
Who first described the process of cc in 1904?
Pavlov from his observations of salivation, dogs automatically salivate when presented with food - reflex response and no learning is required (automatic)
A01: pavlov dog
-food UCS salivation UR
-conditioned dog to salivate to sound of a bell(NS-> CS) repeatedly presented food whilst ringing the bell.
-The NS (bell) is repeatedly paired with an UCS (food), the two become associated, resulting in the NS becoming a CS to create a previously instinctive and now conditioned response (salivating)
Evaluation of Pavlov (2 )
(+)experimental method, Controlled conditions. manipulating the UCS and NS (IV), was able to accurately measure the amount the dog salivated (DV). Cause & effect relationship between stimulus and response.
(-)non-human animals. doesnt reveal alot abt human behaviour. Humans have free will behaviour not purely determined by association made between stimulus and response. Conclusions abt CC may not provide a valid explanation of all human behaviour as extrapolating findings
Operant conditioning A01
-learning by consequences (reinforcement) of ones own behaviour
-something in environment strengthens behaviour more likely to occur. example…
Types of reinforcement
1)Positive: receiving a reward when a certain behaviour is peformed. More likely to reoccur if its reawrded by positive consequences
2)Negative:rewarded by avoiding something unpleasant. More likely if rewarded by avoiding something unpleasant
3)Punishment: unpleasant consequence. Less likely to reoccur if it results in negative consequences
Skinner positive reinforcement (PR) A01
skinner box (SB)
positive: hungry rat in SB, accidently knock lever, food pellet drop = PR, learnt to go straight to lever after a few times. they were conditioned to engage in unnatural behaviour (learned) of pushing a lever
Skinner negative reinforcement (NR) A01
rat in SB, electric current, accidently knock lever, immediatley switch off (unpleasant stimulus stopped). NR for behaviour. Quickly leanred to go straight for the lever after few times of being placed in box.
skinner punishment (P) A01
- define punishment
-once rat was taught to press lever, skinner trained it to cease this behaviour by electrifying the floor each time the lever was pressed.
skinner operant conditioning A03 (2)
(+)experimental method, controlled conditions (SB). BY manipulating consequences of behaviour (IV), he was able to accuratley measure the effect on the rats behaviour (positive or negative) and the future frequency of its occurence.
(-)Non-human animals. (same as CC point). However, skinner argued that free will was merely an illusion and that all behaviour is the product of external influences so testing animals is a valid way to investigate human behaviour.
Evaluation of the behaviourist approach (1: prctical application)
(+)Practical application such as counter conditioning treatments, flooding and systematic desensitisation.The effectiveness of these therapies suggests that the behaviourist principles that they are based on must have some validity and merit.
Evaluation of behaviourist approach A03 (other than practical applications 3 other points)
BP= behavioural psychologists
(+)supported by evidence: pavlov and skinner findings summary
(-)Over-simplistic as it favours nurture side of nature vs nuture debate. BP believe B is learned through OP and CC & they therefore ignore wealth of evidence to suggest bio factors also contribute (e.g.genes or hormones). Very one-sided view of human B and doesn’t provide a holistic explanation.
(-)Supports the determinism side of the freewill vs determinism debate. BP claim that HB is product of external influences (environmental determanism) and, as the individual cannot cotrol these processes, they cant be held responsible for their own behaviour. many psychologist would disagree with this view and believe humans have the free will to choose how to behave e.g.humanistic P
Social learning theory (SLT) basic assumptions
1)behaviour is learnt from the environment and thus genetic don’t influence behaviour
2)Behaviour is learnt from observing others (role models) and the reinforcement or punishment they recieve. From this, individuals will decide whether to imitate the behaviour or not.
