In a functional analysis, which test condition set is typically used to identify maintaining functions?

• A. Hunger, Thirst, Pain, Fatigue
• B. Verbal, Nonverbal, Social, Tangible
• C. Attention, Escape, Alone, and Control (Play)
• D. Positive reinforcement, Negative reinforcement, Punishment, Extinction

Answer: (C)

The main idea is that a functional analysis uses specific test conditions to reveal what reinforces a behavior. In a standard FA, the set of test conditions is built to isolate social reinforcers and automatic reinforcement: attention, escape, alone, and a play/control condition. By presenting each condition separately and measuring when the problem behavior increases, you can identify the function maintaining the behavior. If the behavior rises in the Attention condition, it’s attention-maintained; if it rises in the Escape condition, it’s escape-maintained; if it rises in the Alone condition, it’s automatic reinforcement; and the Play (control) condition provides a baseline to show that the behavior occurs more under those specific contingencies than when none are in effect. This combination is why those four elements—Attention, Escape, Alone, and Play (Control)—are characteristic of the typical FA test set. The other options don’t match this standard setup. Internal physiological states like hunger or thirst aren’t used as FA test conditions. The categories Verbal, Nonverbal, Social, Tangible refer more to potential reinforcer modalities rather than the structured test conditions designed to elicit and differentiate functions. And the grouping of positive reinforcement, negative reinforcement, punishment, and extinction describes types of contingencies or procedures, not the specific test conditions used to identify maintaining functions.
