A BCaBA is teaching a student to stay on-task. The student is reinforced for on-task behavior that starts at 2 minutes, then increases to 4, 6, and eventually 10 minutes. The behavior remains the same—only the length changes. This is an example of:

Which of the following is a critical component of a token economy system?

A student is shown a picture of a cat (sample stimulus) and is presented with three choices: cat, dog, and fish. The student selects the cat. This is an example of:

A therapist physically guides a learner to zip a coat. As the learner starts to initiate the movement independently, the therapist reduces her contact to just the wrist, and then eventually removes her hands completely. What prompting strategy is being used?

A student who is frequently scolded for incorrect math answers begins skipping math class altogether. Which side effect of punishment is being demonstrated?

A behavior analyst uses a scatterplot to identify time patterns related to a student’s aggression. What kind of assessment tool is this?

A behavior analyst implements extinction to reduce a child’s screaming, which was previously maintained by escape from tasks. After consistent implementation, the screaming behavior decreases to near zero. Two weeks later, during a routine work session, the child suddenly screams once again but then resumes working as usual and does not scream again afterward.What does this single unexpected return of behavior best illustrate?

A therapist is trying to reduce a student’s attention-seeking behavior (shouting) by placing it on extinction—ignoring the shouting completely. Despite this, the student continues shouting loudly for several weeks, even after attention is consistently withheld.Which concept best explains why the behavior is persisting despite the extinction procedure?

A teacher gives a student attention every time they interrupt her during class. Over time, the student’s interruptions increase. This is an example of:
