What is a probe in functional analysis or single-subject design?

• A. A probe is a repeated measurement of the target behavior under identical training conditions.
• B. A probe is a test of the target behavior under specific conditions to assess potential contingency changes or generalization; used to monitor maintenance of skill.
• C. A probe is a tool to punish inappropriate behavior.
• D. A probe is an informal observation with no specific conditions.

Answer: (B)

In functional analysis and single-subject designs, a probe is a targeted test of the target behavior conducted under specific conditions that differ from the training context. The goal is to see whether the behavior appears or persists when contingencies are changed, whether it generalizes to new settings or people, and whether it is maintained over time without continuous reinforcement. Probes help determine if the skill is robust beyond the exact conditions of training. They’re not about punishment, and they’re not simply informal observations with no controlled conditions. They’re also not just repeated measurements under the same conditions. Therefore, testing under specific conditions to assess changes in contingencies or generalization and to monitor maintenance best describes what a probe is.
