| Unconditioned Response | Response that takes place in an organism whenever an unconditioned stimulus occurs. |
| Conditioned Stimulus | Originally neutral stimulus that is paired with an unconditioned stimulus and eventually produces the desired response in an organism when presented alone. |
| Conditioned Response | After conditioning, the response an organism produces when only a conditioned stimulus is presented. |
| Unconditioned Stimulus | Stimulus that invariably causes an organism to respond in a specific way. |
| Neutral Stimulus | Any input that does not set off a particular unconditioned reflex. |
| Extinction | presentation of CS without US leads to a lessening of responding and then no response |
| Spontaneous Recovery | the reappearance of the CR after a pause in extinction trials |
| Response generalization | CR triggered by stimulus similar to the CS (e.g., Little Albert) |
