Which term describes the form of a response?

• A. Time sampling
• B. Stimulus control
• C. Temporal locus
• D. Topography

Answer: (D)

Topography describes the physical form of the response—the shape, movements, and observable configuration of the behavior when it is emitted. It is about what the behavior looks like, such as whether a child says a word, signs, or points to indicate the same message, even though the function may be similar.

Time sampling refers to a measurement approach that records whether a behavior occurs during designated intervals, not the way the behavior is performed. Stimulus control involves how antecedent cues influence the likelihood of the response, focusing on what triggers the behavior rather than how it looks. Temporal locus concerns when the response occurs in relation to a stimulus, i.e., timing, not the form.
