We reviewed twelve studies that used the constant time delay (CTD) procedure to teach chained tasks to individuals with developmental disabilities from years 1996-2006. Variables analyzed include types of tasks that have been taught with the procedure, how effective CTD has been in teaching participants, and whether researchers have investigated…

A 10-year-old autistic child was trained to imitate verbal prompts describing the child's motor responses. When intervention was introduced in the form of a gradual delay in the presentation of the verbal prompts, the child's spontaneous speech on trained items increased. Generalization and maintenance were analyzed. (Author/JDD)

The study found that a pragmatic teaching strategy based on milieu teaching and time-delay procedures was effective in teaching four nonspeaking, developmentally delayed children (ages five and six) using manual communication boards to initiate requests for information (i.e., who, what, and where) (DB)

The self-monitoring and generalization behaviors of eight preschool children were observed as they progressed in management programs for their developmental phonological disorders. Self-monitoring behaviors varied in type, frequency, and point of onset in relation to generalization data. Self-monitoring behaviors did not always nor only occur in…

A 5-second constant time delay procedure was used to teach 10 word definitions to 3 fifth grade students with mild learning handicaps. All students learned the definitions in 8 to 9 sessions with students maintaining correct responding at 6, 10, and 14 weeks after training. Generalization was also observed. (Author/DB)

A time delay procedure was used to teach three children (ages 5-9) with autism to ask the question "What's that?" when novel stimuli were presented, and generalization of the skill was assessed. Results suggest that children with autism can be taught to ask questions that lead to acquisition of new information. (Author/DB)

This study, with six high school students with moderate to severe disabilities, found that students who received concurrent sequence training demonstrated better generalized performance in three nontrained grocery stores than students who had received serial sequence training, once training criterion was attained though training required more…

Ten staff members of residential facilities for individuals with mental retardation were trained in self-monitoring procedures, to increase staff on-task behavior and adherence to scheduled activities. Increases in both on-schedule and on-task behavior resulted, and generalization to evening hours occurred. Supervisor feedback was subsequently…
