This study compared two prompting procedures that are used to teach children with autism in discrete trial: graduated guidance and system of least prompts. A modified alternating treatment design (ABCBC) was used to compare four children's acquisition of object labels taught by a system of least prompts and taught by graduated guidance. Two children were taught with the system of least prompts procedure first and the graduated guidance training procedure second. The other two children were taught with the graduated guidance procedure first, and the system of least prompts training procedure second. Each treatment phase involved three consecutive daily training sessions with 100 training trials each session. Probes were done each session on object labels taught by the current method up to that point All four children performed better when taught by a system of least prompts rather than when taught by graduated guidance. More object labels were acquired and maintained in the system of least prompts condition. These results indicate that the system of least prompts may be superior to graduated guidance when used in a discrete trial format.
