Which term describes a clear, objective description of observable behavior features?

The term that describes a clear, objective description of observable behavior features is an operational definition. This concept is essential in behavioral sciences and research because it provides a specific, measurable way to define behaviors, ensuring that they can be reliably observed and analyzed. By using an operational definition, practitioners can communicate about the behavior in a standardized way, which facilitates understanding, replication, and assessment in research or clinical settings.

Operational definitions do not involve subjective interpretations but focus strictly on observable characteristics. For example, instead of saying a child is "aggressive," an operational definition might describe specific actions such as "hitting another child or yelling loudly." This clarity allows for consistent observation and measurement of the behavior over time or across different situations.

In contrast, a model prompt refers to demonstrating a behavior to encourage its occurrence, negative reinforcement involves encouraging a behavior by removing an adverse stimulus, and the most-to-least prompt is a strategy used in teaching to gradually reduce the assistance provided. These concepts do not address the need for clear and objective measurement of observable behaviors like an operational definition does.
