Experimental Analysis of the Relationship Between Speaking Rate and Stuttering During Mother-Child Conversation

摘要

This study investigated the relationship between stuttering and speaking rates in a 4 year-old male child who stuttered and the child's mother during conversations. A single-subject experimental time-series design (ABCDA) was used to investigate the effect of decreasing the speaking rates of both the mother and the child on stuttering. Decreasing speaking rates of both the mother and child produced a decrease in the stuttering rate of the child, not accompanied by reductions in either linguistic complexity or frequency of interruption. The diminished stuttering observed during manipulation generalized to other speaking situations.
