In а clаssrооm, students cоmplete mаth and reading activities on alternating days. Across both activity types, the teacher implements a reinforcement system (stickers for participation and accuracy). However, because she is short on time, the teacher removes the reinforcement system during math. The next day during reading, she notices an increase in the students’ participation and accuracy - even though nothing changed in her approach to reading. This pattern illustrates . Specifically, the change in the students' behavior is .
