The Scope of Phonological Encoding Plans for Stutterers

The picture-word interference paradigm was used to examine the scope of phonological encoding plans of stutterers using two indicators: naming latency and error rate. The experiment requires participants to generate sentences containing three image names in their spoken language, while visually presenting interfering words and manipulating their phonetic correlations. The results showed that stutterers only had a phonological facilitation effect on the first noun, and there was no phonological facilitation effect or lexical interference effect on the second and third nouns, indicating that the scope of the stutterer’s phonological encoding plan was the first noun.
