In which scenario would stimulus generalization be most effectively illustrated?

The choice highlighting the scenario where a student generalizes a skill across multiple settings effectively illustrates stimulus generalization. This concept refers to the ability of an individual to apply what they have learned in one context to different but similar contexts. When a student demonstrates a skill in various environments—such as at home, in school, or during community outings—it shows that the learned behavior is not reliant on a specific stimulus or situation. This broader application indicates that the student understands the underlying principles of the skill and can transcribe it across different settings, showcasing adaptability and learning transfer.

In contrast, limiting interactions to only one setting implies a lack of generalization to other environments. When a student responds only in a specific manner or only under certain prompts, this suggests the behavior has not generalized beyond its original context. Both these scenarios do not exemplify the concept of stimulus generalization as effectively as the situation where skills are applied across multiple settings.
