Ramona takes her 4-year-old daughter to a park. While her daughter plays in the sand pit, Ramona sits and chats with her friends. When she hears two girls fighting, she does not worry as she recognizes that it's not her daughter's voice. The given scenario illustrates:

B) stimulus discrimination.

Explanation:

Stimulus discrimination is a psychological term for responding to one certain stimulus, and we learn not to respond to other ones that are similar.

If Ramona responded to the girl's voice, just because she recognizes it is a female child's voice, that would be an example of stimulus generalization - responding to certain stimuli and other similar ones.

But learning to distinguish one certain stimulus from the different ones is stimulus discrimination.

This is usually used as a treatment for post-traumatic stress disorder, in which patients are taught to recognize which stimuli do cause danger and which is actually the safe one.
