|February 1, 1986
Summary
This study found that young stutterers exhibit diverse disfluency patterns. Laterality preferences, specifically ear dominance, did not correlate with these stuttering variations in children.
Area of Science:
- Speech-language pathology
- Neuroscience
- Developmental psychology
Background:
- Stuttering (stammering) is a complex speech disorder affecting fluency.
- Understanding the underlying neurological and developmental factors in stuttering is crucial.
- Laterality, or brain hemisphere dominance, has been investigated as a potential factor in stuttering.
Purpose of the Study:
- To investigate the relationship between laterality preferences and disfluency patterns in young stutterers.
- To explore the heterogeneity of stuttering in children based on speech characteristics.
Main Methods:
- Examined disfluency patterns in 86 young stutterers.
- Assessed laterality preferences using a dichotic consonant-vowel listening task.
- Correlated specific disfluency variables with ear preferences.
Main Results:
- Results indicated that young stutterers represent a heterogeneous group regarding their speech disfluencies.
- No significant relationship was found between specific disfluency variables and ear preferences on the dichotic listening task.
- Laterality preference did not appear to be a differentiating factor for stuttering patterns in this cohort.
Conclusions:
- Young stutterers are not a monolithic group; their disfluency patterns vary significantly.
- Ear preference, as measured by dichotic listening, is not directly linked to the observed disfluency patterns in this population.
- Further research is needed to understand the multifaceted nature of stuttering and its potential neurological underpinnings.
