Effect of a 4 s constant time delay (CTD) procedure on motor skill completion (MSC) durations was examined. Participants were 4 adolescents (3 males and 1 female) with severe intellectual disabilities, ages 16 to 19 years. A single-subject multiple probe design was used for experimental control. Duration data were visually inspected in the celeration line approach and statistically tested using the probability table of Bloom (1975). Results indicated that data patterns between adjacent baseline and intervention phases were visually different and statistically significant in the direction of less time. The CTD procedure was effective in decreasing MSC durations.
