Which term is used for a description of measurements and criteria to judge a response?

• A. Environment
• B. Operational definition
• C. Repertoire
• D. Topography

Answer: (B)

Defining exactly how a behavior will be measured and judged is the focus here. An operational definition lays out observable, objective criteria for what counts as the response and how to measure it, so data are reliable and can be compared across observers and settings. For example, to count a communication response, you might specify that it must be spoken aloud in a clear voice, occur within two seconds of a prompt, and be free of inaudible partial words; each instance is counted under those rules. This clarity distinguishes measurements from broader concepts like the environment (the setting and stimuli), repertoire (the range of behaviors a person can perform), or topography (the form of the behavior). Those terms describe places, capabilities, or appearances of behavior, not the exact measurement criteria used to judge it.
