Recent studies indicate that lexical and semantic deficits in children with developmental language disorder (DLD) are not caused only by reduced vocabulary and retrieval difficulties but also by sparse lexical-semantic network and deficits in semantic organization. This paper investigates qualitative differences in the lexical processing between children with DLD and typically developing peers, as well as developmental trends in the lexical-semantic processing in preschool and early school-age children with DLD. The sample consisted of 115 participants (5–8 yr.), 60 children with DLD and 55 typically developing (TD) children. The sample was also divided in two age groups, preschool (5 and 6 yr.) and school-aged groups (7 and 8 yr.). Word association task was used for the assessment of lexical-semantic processing. The responses were coded either as mature associations (paradigmatic and syntagmatic), immature associations (phonological, unrelated and echolalic) or omissions. The results show that DLD children have significantly less mature associations and more immature associations. Also, the performance of children with DLD was significantly poorer at early school age compared to their TD peers. Sparse lexical-semantic network and deficits of semantic organization in DLD children are caused by poor semantic fields and semantic categories, as well as difficulties in the activation of lexicon. However, developmental trends analysis showed that DLD children, although significantly delayed in lexical processing, have similar developmental pattern like TD children.
Selective mutism (SM) is a disorder described from two aspects, psychological and language disorders. Researchers mainly focused on the psychological dimension of SM. However, there is an increasing number of studies indicating a significant speech and language (SL) impairment in children with SM and the possible connection between difficulties in language development and the occurrence of SM at school age. Objective. The aim of this paper was to review available research on SL deficits in children with SM, in order to clarify the cause-and-effect relationships between language and anxiety disorders in these children. Methods. Databases of the Library Consortium of Serbia and relevant Internet search engines were used for the literature search. Results. Nine research studies on SL abilities in children with SM are available in the literature. Mixed and expressive types of developmental language disorder, developmental phonological disorder, and language processing deficits are the most common SL impairments in children with SM. They occur significantly more frequently in children with SM than in children with anxiety disorders without SM and typically developing children. These deficits are often associated with learning disorders, social skills difficulties, and the risk of behavioral problems at school age. Conclusion. Existing studies have provided valuable insights into some aspects of the SL development in children with SM. However, the relationship between language deficits and anxiety symptoms is still not clear. Research on the early SL development in these children, which could shed light on the complex cause-and-effect dynamics of language and anxiety disorders seen in children with SM, is particularly scarce.
Hypokinetic dysarthria is characterized by a speech that gradually becomes monotonous, poorly modulated, quiet and ultimately unintelligible. The goal of this research is to determine the acoustic characteristics of voice and speech in adults with hypokinetic dysarthria and the impact of the altered voice on the quality of communication. The sample consisted of 30 elderly respondents of both genders with Parkinson’s disease and hypokinetic dysarthria. In order to conduct a spectral analysis, the voice of patients was recorded while they were reading phonetically balanced text. The respondents conducted a self-assessment of the degree of their own handicap caused by voice disorder and impact of the voice handicap by completing the Voice Handicap Index (VHI). Statistically significant differences were determined in the position of some formants in respondents compared to the values of formants in typical speakers for the following vowels: F1 of the vowel /I/ and F2 of the vowels /E/, /I/, /O/ and /U/. By examining the relation between the score achieved on the VHI instrument and the value of formants, the only statistically significant correlation was achieved between the formant F1 of the vowel /A/ and functional and emotional subscale. By regression analysis used to determine the predictor of the quality of communication, it was confirmed that F1 of the vowel /A/ has a statistically significant contribution to the explanation of the score achieved on functional and emotional subscale, by explaining 15% of the functional subscale (Beta=−0,393 (11,30 – 47,37)) and 10% of the emotional subscale (Beta=−0,363 (−0,052 – 0,000)).
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.
