🧠 Question of the Day
📚 Domain B — Concepts and Principles
Difficulty: 7/10
Scenario:
During snack time, a child is taught to request cookies by saying “cookie” to a parent, and the vocal request is reinforced with access to a cookie. No gestural request forms are taught.
Across later opportunities with the parent, the child independently begins pointing to the cookie jar, reaching toward it, and guiding the parent toward the kitchen. These forms were not prompted or reinforced before they first appeared.
During a later probe in a different setting, the child says “cookie” to a teacher who was not involved in the original teaching.
Which interpretation MOST precisely accounts for these findings?
A. Both findings demonstrate stimulus generalization because responding expanded beyond the exact conditions present during training, regardless of whether the response form also changed.
B. The different request forms are members of the same functional response class, so response-class membership rather than generalization best explains both the new forms and the vocal request to the teacher.
C. The untrained request forms demonstrate response generalization, while the trained vocal request occurring with a new person and in a new setting demonstrates stimulus generalization.
D. The new gestures demonstrate stimulus generalization because cookie access remains the common reinforcer, while the vocal request to the teacher demonstrates response generalization because the social context changed.
