Your heart may race when confronted by a baby lion but not when approached by a house cat. This best illustrates the adaptive value of discrimination. generalization. spontaneous recovery. acquisition.

## Step 1<br />The problem presents a scenario where a person's heart races when confronted by a baby lion but not when approached by a house cat. This situation is a classic example of discrimination in psychology.<br /><br />## Step 2<br />Discrimination, in this context, refers to the ability to differentiate between different stimuli and respond differently based on the nature of the stimulus. In this case, the person is able to distinguish between a baby lion and a house cat, and responds differently to each.<br /><br />## Step 3<br />The other options provided, such as generalization, spontaneous recovery, and acquisition, do not apply to this scenario. Generalization refers to the tendency to respond in the same way to different but similar stimuli. Spontaneous recovery refers to the reappearance of a conditioned response after a rest period. Acquisition refers to the initial stage of learning when a response is first established.
