Which concept refers to stimuli becoming perceived as equivalent through learning, involving reflexivity, symmetry, and transitivity?

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

Answer: (A)

Stimulus equivalence is the idea that stimuli can come to be treated as interchangeable through learning, so responses to one member of a set can substitute for responses to another. The defining features—reflexivity, symmetry, and transitivity—show how this happens. Reflexivity means a stimulus is related to itself (A is related to A). Symmetry means if A is related to B, then B is related to A. Transitivity means if A is related to B and B is related to C, then A is related to C. When these properties emerge, the set of stimuli forms an equivalence class, allowing untrained relations to arise. For example, after teaching that A is the same as B and B is the same as C, you often see that A is the same as C and C is the same as A even without direct instruction, demonstrating derived, equivalence-based responding.
