[U6Q] Brexten, an 8-year-old, needs to increase his daily physical activity to at least 45 minutes for health reasons, as prescribed by his doctor. When asked to run on a treadmill, Brexten becomes agitated and starts kicking others. Despite this behavior, staff are willing to tolerate it because of the health necessity.

[U6Q] Jamie, a behavior analyst, is working with a client in a classroom setting. The client is learning multiplication tables but emits loud shrieking noises during multiplication fluency drills.

[U6Q] Ava provides support to an individual who repeatedly hits their chin with their knuckles throughout the day and in various settings. A medical evaluation has ruled out any biological causes. Functional analysis results show that the behavior is maintained by automatic reinforcement, though a specific reinforcing response property has not been identified. Ava observes that chin-hitting occurs less frequently when a movie is played. Given this scenario, which intervention would be most appropriate for Ava to use?

[U6Q] Devon scratches his scalp vigorously every minute, causing redness and scabs. This behavior appears maintained by automatic reinforcement. Which intervention should the behavior analyst implement first?

Taylor aims to teach the student to wait for a turn. Which intervention is most appropriate?

[U6Q] Jordan works with Eli, a learner who vigorously rubs her arms across settings, resulting in bruising and skin infections. A medical exam ruled out dermatologic issues. A functional analysis indicates the behavior is maintained by automatic reinforcement, though the specific sensory stimulation is unclear. Jordan observes that Eli rarely engages with toys or leisure activities, spending most of her time watching videos and rubbing her arms. Notably, arm-rubbing decreases when classical music plays. Based on this scenario, which intervention would be most appropriate for Jordan to use?

[U6Q] Mia requests clarification during math lessons once every 3 minutes on average, interrupting instruction.
