Classical conditioning is the process of linking two stimuli to produce a response. There are 3 phases for classical conditioning:
Phase 1 (before conditioning): During this phase an unconditioned stimulus is paired to produce an unconditioned response. An unconditioned response naturally triggers a response.
Phase 2 (During conditioning): This phase involves pairing a neutral stimulus with an unconditioned stimulus so that the neutral stimulus becomes the conditioned stimulus. The neutral stimulus does not naturally trigger a response.
Phase 3 (after condition): In this phase only the conditioned stimulus is presented to produce a conditioned response. The conditioned response triggers a response after pairing with an unconditioned stimulus
