definition of psychology
scientific study of the human mind and its functions and how these influence human behaviour
wundt-father of psychology
-set up first laboratory in Germany 1879
-wanted to investigate nature of human consciousness known as introspection
-believed in experimental method/scientific methods
-Wundt recorded participants own conscious thoughts by breaking them down into basic structures of thoughts, feelings
-isolating tiny consciousness is called structuralism
-introspection still used today in therapies
empricism
belief that all knowledge is derived from sensory experience
scientific method
use of investigative methods that are subjective, systematic and replicable
A03 for origins of psychology
Lack of ecological Validity-weakness
Introspection lacks validity-weakness
Contribution to approaches in psychology-strength
LIC
behavioruist approach
only classical conditioning and operant conditoning
learning approach umbrella
leanring approach is all 3
classical conditioning
operant conditioning
social learning theory
behaviourist approach
-approach only interested in studying behaviour that can be observed and measured
-not interested in investigating mental processes of mind as seen as irrelevant
-John b Watson rejected introspection as involved too many concepts vague and difficult to measure
-behaviourist tried to maintain more control and objectivity
-relied on lab studies
-believe born tabula rasa ‘as a blank slate’ written on by experience
-also suggest basic processes that govern learning 1are same in all species hence why humans can be replaced in experimental methods
classical conditioning
learning through associations between unconditioned stimulus and neutral stimulus
-pavolov researched salivation of dogs
little albert-wayne and rayner study
baby exposed to white rat showed no fear
baby exposed to sound of hammer hitting steel bar started to cry
then exposed baby with both rat and hammer sound and baby found fear
found fear to anything white and fluffy e.g. Santa’s beard
what did Pavlov do
before conditoning
food response
unconditioned stimulus
operant conditioning
A type of learning where
behaviour is acquired and maintained based on its
consequences. Reinforcement increases the
likelihood of the observed behavior being
repeated, whilst punishment (an unpleasant
consequence of behavior) decreases this likelihood
two types of reinforcement
positive reinforcement
negative reinforcement
positive pun
empiricism
belief that all knowledge is deprived from sensory experience(what we can see/hear)
A03 points for behaviourist approach
Reductionism
Use of animals
Scientific methods
scientific method
use of investigative methods that are objective, systematic and replicable
a03 points for origins of psychology
lack of ecological validity
concentrating on objectivity and control in observations, leads to tell us little about how people act in natural real life environments
criticised for not being generalisable to situations outside a controlled, lab setting
leanrning approach umbrella
classical conditioning
operant conditioning
social learning theory
classical conditioning diagram
before conditioning
food = salivation
(ucs) (ucr)
before conditioning
bell = no salivation
neutral stimulus no conditioned resp
during conditioning
salivation
bell + food = unconditoned repsonse
after conditoning
bell salivation
conditoned stimulus = conditoned reps
little albert
to investigate if emotional response can be classically conditioned into 1 month year old baby
-first exposed to white rabbit and showed no fear
-then exposed to sound of hammer striking metal bar and started crying
-then exposed baby to both white rat and hammer sound
-in end, baby feared by white rat at moment he saw it
-his fear generalised to other white furry things e.g santa clause
operant conditioning
BF skinner
leanring through consequences such as reward i.e reinforcement or punishment
organisms spontaneously produce different behaviours, these behaviours produce consequences
consequences may be positive (desirable) or negative (Undesirable)
can determine whether or not behaviour repeated
relationship between reinforcement and punishment
reinforcement increases likelihood behaviour is repeated
punishment decreases likelihood behaviour will be repeated
3 umbrella to operant conditioning
postive reinfrocement
negative reinforcement
punishment
skinners box
-used to investigate opernat conditioning on rats
-rat runs round cage
-when accidnetly presses lever, food pellet (reward) falls in cage
-rat then starts pressing lever purposely to get food
-rat learnt through postive reinforcement that action results in postive consequence (food)
-also experimented with unpleasant stimulus e.g loud noise
-if rat presses lever, loud noise stops
-through negative reinfrocement that action resulted in removal of unpleasant stimulus
-finally, if rat presses lever get electric shock
-showing punishment
-decrease in amount of times lever was pressed as rat understood unpleasnt consequence so behaviour no longer repeated
