Which concept is the ability to recognize a stimulus as equivalent to itself?

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

Answer: (A)

Reflexivity is the ability to recognize a stimulus as identical to itself. In behavior-analytic terms, this means the relation where a stimulus relates to itself—A relates to A. It’s demonstrated when a person can identify or match the exact same stimulus without any mediation by a different cue, confirming that the stimulus is the same as itself. This fits the scenario because the question describes recognizing a stimulus as equivalent to itself, which is the defining feature of reflexivity. Stimulus equivalence, while related, refers to a broader set of relations (including reflexivity, symmetry, and transitivity) that allow derived connections among different stimuli. Symmetry would involve a bidirectional relationship (if A relates to B, then B relates to A), and transitivity involves chaining relations (if A relates to B and B relates to C, then A relates to C).
