Background: Stuttering is one of the most prevalent speech and language disorders. Symptomatology of stuttering has been surveyed from biological, developmental, environmental, emotional, learning and linguistic viewpoints. Literature shows that syllable structure as a linguistic feature, may influence the frequency of disfluencies.Objectives: This study aimed to determine the effect of syllable structure on the frequency of disfluencies in adults with stuttering. Patients and Methods: This cross-sectional descriptive-analytic study was performed on 16 adults (14 males and 2 females) who stutter with the mean age of 24.56 years. The frequency of disfluencies was evaluated by asking the subjects to read two lists, one list contained 60 words and another one consisted of 60 nonwords. The words and nonwords were selected based on simple and difficult syllable structures. The data were statistically analyzed through paired t-test using the SPSS software.
Results:The results of this study showed a significant difference between the frequency of disfluencies between the simple syllable structures and difficult syllable structures in nonword reading tasks (P < 0.05). There was no significant difference in the frequency of disfluencies between the simple syllable structures and difficult syllable structures in word reading tasks (P > 0.05).
Conclusions:The findings of this study indicate that the frequency of disfluencies was increased in difficult syllable structures in comparison to simple syllable structures. According to the results, it seems that certain linguistic features, such as syllable structure can affect speech-motor output in people who stutter through affecting phonological encoding.
Background & Objectives:The educational environment and family are of the most important factors in the growth and development of linguistic and verbal skills of a child. Certain conditions such as environment can influence the linguistic characteristics of the child. This study aimed to examine the syntax comprehension of Persian language speaking children among foster families and typically-developing children.Methods: 72 Persian speaking children living in orphanages between the ages 4 to 6 and 75 typically-developing 4 to 6 year-old children were assessed by the Persian syntax comprehension test. This test measures 24 syntactic constructs of Persian language in 96 items. Also, the Mann-Whitney Test was used to compare the groups.
Results:Given the results of the Persian syntax comprehension test, the mean syntax compression score of children living in orphanages were significantly lower than those of typically-developing children (P<0.05).
Conclusion:The foster children should be more paid attention to, in order to particularly enhance their syntax comprehension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
