There are 4 things that could happen after Conditioning, Stimulus Generalisation, Stimulus Discrimination, Extinction and SpontaneousRecovery
Stimulus Generation - another stimulus similar to the Conditioned Stimulus may also trigger a Conditional Response
Stimulus Discrimination - Only the ConditionedStimulus triggers the Conditional Response, no other Stimulus
Extinction - Strength of ConditionedResponse Reflex decreases over time as ConditionedStimulus is presented alone repeatedly without UnconditionedStimulus
Spontaneous Recovery - ConditionedResponse may occasionally and temporarily reappear even if ConditionedResponse has been extinguished
