1. Classical Conditioning

2. Before training, the stimulus that has no effect
Neutral Stimulus (NS)
Before training, the stimulus that has no effect

3. Unconditioned Stimulus (UCS)
Any stimulus that can evoke a response without the organism going through any previous learning (no training required)

4. Unconditioned Response (UCR)
The response associated with the Unconditioned Stimulus before the experiment with no training required

5. Conditioned Stimulus (CS)
The once Neutral Stimulus that produces a response after training

6. Conditioned Response (CR)
The reaction to the Conditioned Stimulus

7. Extinction
The disappearance of the Conditioned Response after the Conditioned Stimulus is no longer presented with the Unconditioned Stimulus

8. Spontaneous Recovery
After extinction has occurred, the reappearance of the Conditioned Response when the Conditioned Stimulus is presented

9. Generalization
Responding to other stimuli similar to that of the Conditioned Stimulus

10. Responding in a different way to similar stimuli
Discrimination
Responding in a different way to similar stimuli
