Stuttering frequency on meaningful and nonmeaningful words in adults who stutter.

Previous research has suggested that word meaning can influence the loci and frequency of stuttering moments. Based on this proposition, it was hypothesized that people who stutter will exhibit a larger proportion of stuttering moments on meaningful words when compared to nonmeaningful or nonsense words. In order to test this hypothesis, stuttering frequency was examined among 9 English-speaking adults who stutter as they read a total of 126 words that were either meaningful or nonmeaningful in nature. The results indicated that approximately 117% more stuttering moments were recorded on nonmeaningful words when compared to meaningful words and this difference was statistically significant (p=0.01). These findings challenge the notion that word meaning can be considered as a reliable predictor of stuttering frequency.
