4 main assumptions of behaviourist approach
focused on observable behaviour= OBJECTIVE ANALYSIS conducted lab = control over EV reliable data repeatability behaviour is learnt through classical and operant conditioning tabula rasa - blank slate= behaviour is learnt from experiences
classical conditioning meaning
learning through association
Classical Condition BC
unconditioned stimulus ────────────────────────────▶ unconditioned response neutral stimulus ────────────────────────────▶ no response
DC
neutral stimulus + unconditioned stimulus ────────────────────────────▶ unconditioned response
AC
conditioned stimulus ────────────────────────────▶ conditioned response
operant conditioning
learning through consequences voluntarily
4 main elements of OC
Positive reinforcement Negative reinforcement Positive punishment Negative punishment
Positive reinforcement meaning
add a rewarding stimulus to increase the likelihood of a behaviour
Negative reinforcement meaning
REMOVE unpleasant stimulus to increase the likelihood of a behaviour
Positive Punishment
something adding to decrease the likelihood of a behaviour
Negative Punishment
Something removed to decrease the likelihood of a behaviour
one strength of OC(D)
Determinism - allows predictions
2nd strength of OC (R)
Reductionism - controlled lab= more scientific + reliable + internal validity + scientific reliablity
one weaknesses of OC (ED)
Environmental Determinism - ignores free will, seen as mechanistic view
2nd Weaknesses OC (R)
Reductionism - oversimplifies behaviours + ignores cognitive and biological factors
what does reinforcement always mean
always increases a behaviour
what does punishment mean
always decrease a behaviour
what does positive mean
always add
what does negative mean
always remove
Thorndike’s Law of Effect
reward = repeat behaviour punishment = decreases behaviour
