[FinA] One оf the students in Surа's clаssrооm constаntly twirls her hair while reading out loud. Sura notices that the student's reading fluency is disrupted when she twirls her hair. To address this, Sura asks the student to hold the book with both hands while reading. If the student reads out loud while holding the book with both hands, she receives praise. If the student reads with one hand or while twirling her hair, the teacher does not praise the student. Which differential reinforcement procedure is Sura using?
