The purpose of this study was to determine the impact of using preferred characters with a constant time delay instructional procedure to teach community sign reading to three students with moderate intellectual disability with the definitions of the signs as non-targeted information. An adapted alternating treatments design was used to evaluate the effectiveness and efficiency of the preferred characters on acquisition of the community signs. Pre- and post- assessments were conducted on acquisition of the non-targeted definitions, as well as generalization of the signs and their meanings. The results indicated that all students learned the target signs and they learned all of the definitions of the signs when they were presented with a preferred character. Students did not generalize the meanings of the signs to community settings.
