Use of constant time delay and attentional responses with adolescents.

This study investigated the effectiveness of a constant time delay procedure in teaching adolescents with learning or behavior disorders. Subject matter included social studies and health facts presented in small-group settings. In addition, the study assessed the effects of two attentional responses (general--looking at the target stimuli, or specific--repeating the teacher's question) on students' acquisition of other students' facts and of related nontarget information. Two types of feedback for correct responses were presented: praise plus additional information, and general praise only. Results of various measures indicate that (a) the constant time delay procedure was reliable and effective; (b) students not only acquired targeted facts with few errors, but also acquired some other nontargeted facts, such as information presented along with feedback; and (c) specific attentional responses facilitated acquisition of observational and incidental facts and maintenance of learning.
