Behaviourist approach: A way of explaining behaviour in terms of what is observable and in terms of learning
Classical conditioning: Learning by association. occurs when two stimuli are repeatedly paired together- an unconditioned stimulus (UCS) and a new neutral stimulus (NS). The NS will eventually reproduce the same result as the UCS alone.
Operant conditioning: A form of learning in which behaviour is shaped and maintained by its consequences. Incudes positive/negative reinforcement and punishment's.
