Which concept involves recognizing that initially distinct stimuli can become functionally equivalent through learning?

• A. Reflexivity
• B. Transitivity
• C. Stimulus Equivalence
• D. Symmetry

Answer: (C)

Stimulus Equivalence is the idea that distinct stimuli, which start as separate and unrelated, can come to be treated as the same by behavior through learning. After certain training histories (like relations among stimuli), these stimuli form an equivalence class, so presenting one can evoke responses to the others without direct training for those specific pairings. This captures the core notion that functionally related stimuli become interchangeable in behavior. Within this framework, reflexivity is when a stimulus relates to itself, symmetry is when the learned relation goes both ways between two stimuli, and transitivity is when you can derive a new relation from two learned ones (if A relates to B and B relates to C, then A relates to C). These are components or derived relations that can occur within stimulus equivalence, but the broad concept being tested is the formation of functional equivalence among different stimuli through learning.
