Working memory (WM) assessment is often part of cognitive-linguistic test batteries. The author examined the relationship between parent rating of WM functioning and children's performance-based WM, and the relationship of each with receptive and expressive spoken language measures. Study participants were eighty-three 7- to 11-year-old children. The sample represented a broad range of cognitive abilities. No participating child had frank neurological or intellectual disabilities, autism, fluency disorder, or hearing loss...

The involvement of the brain dopamine system in the pathophysiology of developmental stuttering has been previously suggested. In the present study, we aimed to investigate the relationship between developmental stuttering in children and the levels of serum homovanillic acid (HVA), dopamine D2 receptor (DRD2) C957T (rs6277), and solute carrier family 6 member 3 (SLC6A3) human dopamine transporter (hDAT) A559V (rs28364997) single-nucleotide polymorphisms. In a case-control study, serum level of HVA, DRD2 C957T, and DAT A559V were compared between 85 children who stuttered (CWS) and 85 age- and sex-matched children who did not stutter (CWNS)...

BACKGROUND: Parkinson's disease (PD) is a neurological disorder that produces motor and non-motor impairments. The evaluation of motor symptoms is currently performed following the third section of the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS-III); however, only one item of that scale is related to speech impairments. It is necessary to develop a specific scale such that considers those aspects related to speech impairments of the patients. AIMS: (i) To introduce and evaluate the suitability of a modified version of the Frenchay Dysarthria Assessment (m-FDA) scale to quantify the dysarthria level of PD patients; (ii) to objectively model dysarthric speech signals considering four speech dimensions; (iii) to develop a methodology, based on speech processing and machine learning methods, to automatically quantify/predict the dysarthria level of patients with PD...

BACKGROUND: Individuals with traumatic brain injury (TBI) present with numerous discourse deficits associated with impairments to the linguistic system and other cognitive systems. Individuals with TBI may produce discourse that is lacking important information and poorly organized, as well as containing numerous coherence disrupting elements. Yet there are few studies directly addressing discourse deficits in individuals with TBI to guide clinicians. AIMS: The purpose of the study was to determine if discourse processing treatment improved the discourse production in individual with TBI...

PURPOSE: Perceptual assessments remain the most commonly utilized procedure to diagnose and evaluate resonance disorders. However, the discussion continues about which rating scale has to be applied. Therefore, this study aimed to compare the reliability and validity of ordinal and visual analogue scales to rate hypernasality, audible nasal airflow and speech understandability. METHODS: Four experienced speech-language pathologists rated 35 speech samples of children with a range of hypernasality, audible nasal airflow and speech understandability, using an ordinal scale and a visual analogue scale...

The effect of levodopa on perceptual and acoustic measures of voice quality was examined in fifty-one individuals with Parkinson's disease (IWPD). IWPDs produced prolonged vowels while on and off levodopa. Acoustic measures included jitter, shimmer, harmonic-to-noise ratio, cepstral peak prominence and the Acoustic Voice Quality Index. A perceptual measure of overall voice quality was obtained from 3 listeners. When the IWPDs were examined as a group, no significant difference was found between on and off levodopa conditions...

PURPOSE: The primary aim of this study was to analyze the acquisition of different classes of words in Spanish-speaking children with Down syndrome (DS), with special emphasis on nouns and verbs. A second objective was to compare the results obtained with those reported by Checa et al. (2016), who used a different measure to study vocabulary composition. METHOD: We studied 108 children with DS and 108 children with typical development (TD), with mental ages between 9 and 29 months (DS M = 21;26 months;days, TD M = 20;23) and chronological ages between 8;24 and 68;19 months;days (mean = 41;11 and 20;19 for DS and TD, respectively)...

Although bilingual children are thought to be at higher risk for selective mutism (SM), little is known about the development of SM in this population. This study investigates the effects of children's anxiety and language skills and parents' cultural adaptation on the development of SM. 15 bilingual (11 mute, 4 speaking at the beginning of the study) and 15 monolingual children (7 mute, 8 speaking at the beginning of the study) between the ages of 3 years and 5 years 8 months were assessed longitudinally over a 9-month period...

Previous studies have suggested sentential complementation is the crucial ingredient of language that relates to false-belief (FB) reasoning, while the role of relative clauses (RCs) is less clear. Nevertheless, under the hypothesis that clausal embedding has a meta-representational effect, arguably implied in FB, one expects a link between FB and not only complementation but also relativization. Seventeen children with ASD (6 to 16 years, mean age 9;2) were assessed for RCs and FB. Comprehension of RCs significantly predicted FB performance, while none of the controlled factors played a predictive role (comprehension of simple sentences, vocabulary, morpho-syntax and working memory)...

PURPOSE: The fourth version of the Stuttering Severity Instrument (SSI-4) has been available since 2009. It has some modifications and new features which make it more appropriate at least for clinical practice, although further documentation is needed. The objective of the current research was to translate SSI-4 into Persian language and to discuss its relative and absolute reliability as well as its criterion validity for Persian adults who stutter (PWS). We also aimed to study how the new subjective self-reports of the SSI-4 complement the stuttering severity score obtained from the SSI-3 or the SSI-4...

Aphasia, an acquired language disorder resulting from brain damage, affects over one million individuals in the United States alone. Many persons with aphasia (PWA), particularly those with non-fluent aphasia, have been observed to be able to sing the lyrics of songs more easily than they can speak the same words. Remarkably, even humming a melody can facilitate speech output in PWA, and this has been capitalized on in therapies such as Melodic Intonation Therapy. The current study examined PWA's ability to complete phrases from songs by either singing, speaking, or intoning them in an experimental stem-completion format...

This study explores the role of German dative case marking in disentangling effects of specific language impairment (SLI) and bilingualism. Longitudinal data of German-Italian bilingual children with SLI (N = 3) is compared to cross-sectional data (N = 42) of monolingual and bilingual typically developing (TD) children and monolingual children with SLI (ages four and seven). Spontaneous and elicited speech data is analysed in terms of target-like dative case marking in German. Results show differences between the acquisition of case marking of pronouns and of full Determiner Phrases (DPs)...

PURPOSE: To determine the influence of clear speech on auditory-perceptual judgments of speech acceptability and listener comfort for electrolaryngeal speech. METHOD: Voice recordings were obtained from 10 electrolaryngeal speakers. Each speaker read the Rainbow Passage in two conditions: habitual speech and clear speech. Speakers were encouraged to speak as clearly as possible and over-articulate in the clear speech condition. Auditory-perceptual rating tasks were completed by 20 normal-hearing adults who evaluated 20 randomized voice recordings...

Objectively measured speech reception, speech production and expressive and receptive sign skills were compared with the self-assessment ratings of those skills in 96 college students with hearing loss. Participants with no aidable hearing used cochlear implants (CIs) or nothing. Participants with aidable hearing used either hearing aids (HAs) or nothing. Results revealed that individuals using CIs had speech reception and production skills that were as good as or better than students with more hearing who used HAs...

BACKGROUND: 22q11.2 deletion syndrome (22q11.2DS) is a genetic condition associated with a highly variable phenotypic expression. During childhood speech and language deficits are commonly observed. Findings of cross-sectional studies suggest syndrome-specific and changing language profiles, but a longitudinal approach to identify developmental changes is still lacking to date. AIMS: The present study aimed to delineate language characteristics and trajectories by comparing the performance of Dutch-speaking school-aged children with 22q11...
