Answer:
discrimination
Step-by-step explanation:
When a person is able to distinguish between stimuli it is known as discrimination. The opposite condition is called generalization.
Here, Alicia is able to distinguish between a spider and spider in a photograph. This means that she is able to discriminate between the stimuli.
If she would get scared by the photograph of a spider then this situation would be generalization.
Hence, the statement here is referring to discrimination.
