Mary is a kindergartner in Mrs. Smith's kindergarten classroom. Nearly every day when the students are called to sit on the rug at circle time, Mary shouts "No!" and runs around the room. The teacher ends up chasing her and calling the principal who comes down to escort Mary to the office for a timeout. After the timeout, Mary talks with the principal about her behavior and returns to class.
What would the target behavior be in this example? Is is sitting on the rug or screaming No?
Also what are some possible antecedents and consequences for her behavior?
