ABSTRACT
This study investigated the effectiveness of delayed, directive praise on the on-task behavior of children identified as having a low level of attention. Utilizing an A-B-A-B single subject design, each child received delayed praise, employed as a directive for future behavior, from his or her classroom teacher during the treatment phases. The on-task behavior of each participant rose substantially between the initial baseline and treatment conditions and remained elevated throughout the study. Similarities between student performances suggest that students with low on-task behavior respond positively to delayed, directive praise and that the positive effects of such praise generalize over time.
