The effect of nonverbal teacher approval on student attentive behavior

Abstract

The effect of contingent nonverbal teacher approval on student attentive behavior was examined in a classroom with 12 retarded children. After baseline data were gathered on contingent verbal and nonverbal teacher approval and student attentive behavior, the teacher was instructed to increase her use of contingent nonverbal approval (smiles and physical contact) and to maintain her baseline level of verbal approval. After a reversal phase, the nonverbal approval phase was reinstated. Nonverbal teacher behaviors increased during the experimental phases, whereas verbal teacher approval (alone or in conjunction with nonverbal behaviors) did not increase. Attentive behavior increased for 11 of 12 students during the phases in which contingent nonverbal teacher approval increased. Correlational data suggested that nonverbal teacher approval accounted for behavior change of the students to a greater extent than did changes in the amount of teacher approval per se or in the teacher's use of verbal approval.
