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
1)
2)Components are…
3)Ppl were trained to do…
4)People were presented with…
- 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?
Watson. subjective as it varied from person to person, difficult to establish general principles. Truly scientific psych should restrict 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)T
2)P
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 PLAN
(-) His research was not scientific
(+)Some aspects would still be considered scientific
(-)low ecological validity
(+)Introspection is till being used as a useful method by modern psychologists
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
(-)Non-human animals
(+)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
Punishment is NOT reinforcement
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
(+)Experimental method, controlled con
(+)experimental method, controlled conditions (Skinner Box) to discover the causal relationship between two or more variables. By manipulating consequences of behaviour (IV), he was able to accuratley measure the effect on the rats behaviour (DV). Strength of Skinners research because it allowed him to establish the cause and effect relationship between the consequences of behaviour (positive or negative) and the future frequency of its occurrence.
Evaluation of the behaviourist approach (1: practical 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.
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.
What are the three types of reinforcement in SLT?
1)Identification
2)Imitation
3)Modelling
