Multiple Choice

Provide an example of an operational definition for a behavior.

Operational definitions specify exactly what counts as the target behavior in observable, measurable terms so everyone records it the same way. The best choice defines the behavior with precise topography, intensity, and duration that can be observed and counted: the learner uses a closed fist to strike their head with enough force to cause a noticeable impact for at least 1 second. This leaves no guesswork about what counts as the behavior and allows reliable measurement. The other options fail to provide this clarity. Describing the behavior as “hits themselves whenever upset” relies on an internal state (upset) and lacks observable criteria. Saying the function is to obtain attention or the antecedent is “when upset” describes why or what happens before the behavior, not the observable behavior itself. Operational definitions must focus on the observable action itself, not its presumed purpose or triggers.
