Discrimination is the ability to distinguish between different stimuli and respond differently to them. In this case, the ability to distinguish a lion (potentially dangerous) from a kitten (not dangerous) is essential for survival. This shows the adaptive value of discrimination. Shaping refers to the gradual reinforcement of behaviors that build up to a more complex behavior, extrinsic motivation refers to the performance of a behavior for external rewards, and spontaneous recovery refers to the reappearance of a previously extinguished behavior after a period of time. None of these concepts are directly related to the example of responding differently to a lion versus a kitten.
