摘要

Background

Stuttering is a neurodevelopmental speech disorder with unclear etiology, linked with auditory processing deficits and associated with Left Ear Advantage. The exact connection between stuttering and auditory processing remains undetermined. The purpose of the current study is to evaluate auditory processing in children with stuttering.

Methods

The clinical group comprised of nine children diagnosed with stuttering, while the control group consisted of nine typically developing children without stuttering. The participants completed an auditory processing battery test including Speech recognition in Babble test, Gaps in Noise test, Dichotic Digits test and Word Recognition-Rhythm Component test. The Mann- Whitney U test was conducted using the Statistical Package for the Social Sciences (SPSS) software to analyze the collected data. Additionally, the laterality index was calculated for both groups.

Results

The clinical group showed significant decreased performance in the gap detection task and in the Word Recognition-Rhythm Component test, both with large effect sizes. The clinical group exhibit left era advantage as it was indicated by the negative laterality index. Despite the fact that no comparison survived the False Discovery Rate correction, the consistency of the effect sizes and the directional patterns across tests support the clinical relevance of these findings.

Discussion

These findings indicate that temporal resolution deficits may be present in stuttering which is consistent with the existing literature. Moreover, in this study children with stuttering exhibit a left ear advantage, whereas earlier research has reported inconsistent patterns. Given the small sample size, future studies with larger cohorts are needed to clarify these results.

Conclusions

The results of this preliminary study suggest highlight the potential risks for broader auditory processing difficulties in stuttering. These findings underscore the potential value of incorporating auditory processing assessment into the clinical evaluation of children who stutter to maximize the therapeutic outcome through auditory training.
