Comprehension of presupposition triggers in cantonese-speaking children with and without autism spectrum disorders.
Abstract Built on a previous finding that children with autism spectrum disorders (ASD) had difficulty comprehending presuppositions, a domain of knowledge which is crucial for successful communication, the present study investigated the comprehension of seven types of presupposition trigger - namely definite descriptions, factive predicates, change-of-state verbs, implicative verbs, iteratives, temporal clauses, and counterfactual conditionals - in Cantonese-speaking children with and without ASD. Twenty-seven children with ASD (mean age 9.07) were compared with 23 typically developing (TD) children matched on ch...

Relationship between temporal processing and phonological awareness in children with speech sound disorders.
Abstract Temporal processing ability contributes to the identification of small phonetic elements that is important for speech perception. Difficulty in these interferes with normal speech perception and phoneme recognition. The present study aimed to assess the temporal and phonological processing abilities in children with speech sound disorders (SSD). Temporal processing and phonological skills were evaluated in 32 participants in the age range of 6-10 years, equally divided into two groups. Group I included typically developing children, and Group II included children with SSD. Gap detection test and dura...

A two-case study of coarticulation in stuttered speech. An articulatory approach.
This study aims to describe the coarticulatory behaviour in stuttered speech from an articulatory point of view. Its purpose is to assess the nature of transitions between a stuttered phone and preceding and subsequent phones. Two persons who stutter were recorded by means of an electromagnetic articulograph while reading a text. The vertical movements of upper and lower lips, tongue body, tongue tip and mandible were extracted. They were then analysed during a stuttering moment and linked to the acoustic type of disfluency. Our findings showed several configurations of coarticulatory behaviour in terms of supraglottic art...

Considerations for Chinese text input methods in the design of speech generating devices: a tutorial.
Abstract Millions of Chinese-speaking people who have the most severe speech disorders could potentially benefit from using Speech Generating Devices (SGDs) to help them participate in society. Entering Chinese text into computer systems is complex, and the process itself requires a translation system from the small selection set of keys to Chinese characters, thus adding to the complexities of adaptive access to computers often required by people who rely on them for spoken and written communication. This paper examines two types of input method: those relying on phonetic principles, and those relying on logograp...

This article investigated the role of semantic transparency in processing root compound nouns in Persian individuals with Broca's aphasia through picture confrontation naming and repetition tasks. The relationship between semantic transparency and affected constituents of nouns showed that semantic transparency had no role in processing compound nouns. The results showed that transparent, opaque and partially transparent compound nouns were processed by dual-routes (holistic and decomposing). Frequency of errors also revealed dissociation of naming and repetition processes as well as simple and compound nouns. The comparis...

Do shared semantic features facilitate Lexical-semantic processing in early course psychosis?
Abstract The lexical-semantic relatedness effect supposes different activation in the semantic memory of related versus unrelated word-pairs. Semantically related pairs are considered to result in a larger spread of activation as the activation of concept nodes is dependent on shared lexical-semantic features of concepts. The increased activation of concepts in the semantic memory in individuals with schizophrenia is found to be, faster spreading and lacking in inhibition in relation to healthy control subjects. The aim of this study was to examine whether the lexical-semantic relatedness effect influences process...

Quantifying phonological knowledge in children with phonological disorder.
In this study, we examine the single-word productions of 275 children with phonological disorder from the Learnability Project (Gierut, 2015b) to confirm the relationship between phonemic inventory - a measure of phonological knowledge - and consonant accuracy - a quantitative, relational measure that directly compares a child's phonological productions to the target (i.e. adult-like) form. Further, we identify potential percentage accuracy cutoff scores that reliably classify sounds as in or out of a child's phonemic inventory in speech-sound probes of varying length. Our findings indicate that the phonemic function of up...

Perceptual and acoustic evaluation of speech production in Down syndrome: A case series.
Abstract People with Down syndrome (DS) can experience difficulties with speech production that can impact on speech intelligibility. In previous research, both perceptual and acoustic analysis has shown that people with DS can have difficulties with speech production in the areas of respiration, phonation, articulation, resonance and prosody. However, these studies have investigated various aspects of speech production separately. No study has examined all components of speech production in one single study and considered how these components, if impaired, may impact on speech intelligibility in DS. This paper pr...

This article addresses the question of whether children classified as having a specific language impairment are such due to a particular problem in inflectional morphology. This has been claimed to be the case for some time. An effort is made here to propose that there may be an age effect behind that result. To support this possibility, a case study of a much older child with specific language impairment is presented. The participant is Tom, a child with a language impairment who underwent language intervention between the ages 9;4 and 10;3. During that period, language samples were taken at five different times (MLUs 5.3...

Most studies conclude that there is a deficit in durational cue processing, whereas the other acoustic stress correlates remain relatively unimpaired. Spanish is a free-stress language in which stress patterns are contrastive, especially in verbal forms (e.g. lavo /'labo/ '[I] wash' vs lavó /la'bo/ '[He/she] washed'). The aim of this preliminary study is to determine whether persons with AOS are able to make the intended stress pattern identifiable ...

Abstract Typically, young children diagnosed with specific language impairment (SLI; also called Developmental language disorder, DLD) have been found to show weakness in narrative development, and such weakness has been judged to be unlikely to resolve over time. However, developmental outcomes for adolescents with a prior SLI diagnosis have not been thoroughly studied. In particular, studies on the evaluative aspects of narratives of such persons are almost non-existent. Here we examine the question whether narrative evaluation of adolescents formerly diagnosed with SLI remains problematic into adolescence or co...

Code-switching in multilinguals with dementia: patterns across speech contexts.
Abstract The study investigates code-switching by multilingual persons with dementia in two different speech contexts, picture naming tests and spontaneous conversation. It combines a psycholinguistic perspective on cognitive and linguistic skills with a qualitative conversation analytic approach to understanding the functions and appropriateness of code-switching in social interaction. The analysis shows that code-switching is used as a resource for compensating for word-retrieval problems in both the naming tests and in word search sequences in conversation. Furthermore, it serves to demarcate meta-communicative...

Parents' contingent responses in communication with 10-month-old children in a clinical group with typical or late babbling.
Abstract Parental responsive behaviour in communication has a positive effect on child speech and language development. Absence of canonical babbling (CB) in 10-month-old infants is considered a risk factor for developmental difficulties, yet little is known about parental responsiveness in this group of children. The purpose of the current study was to examine proportion and type of parental responsive utterances after CB and vocalization utterances respectively in a clinical group of children with otitis media with effusion, with or without cleft palate. Audio-video recordings of interactions in free play situat...

The effect of speech training experiences on speechreading skills of Chinese children with hearing impairment.
In this study, we examine the effect of speech training on speechreading performance of children with HI in China, and how such effect, if any, may be influenced by age. Fifty-nine HI children with speech training experiences, and fifty-eight HI children without speech training experiences completed tasks measuring their ability to speechread Chinese at the linguistic levels of words, phrases, and sentences. The children ranged from 7 to 14 years old, and were divided into four age groups by two-year age intervals. Both accuracy rate and response time data were collected. Results revealed three findings: (1) HI childr...

Estimates of the prevalence of motor speech disorders in children with idiopathic speech delay.
Abstract The goal of this research is to obtain initial estimates of the prevalence of each of four types of motor speech disorders in children with idiopathic Speech Delay (SD) and to use findings to estimate the population-based prevalence of each disorder. Analyses were completed on audio-recorded conversational speech samples from 415 children recruited for research in idiopathic SD in six USA cities during the past three decades. The speech and motor speech status of each participant was cross-classified using standardized measures in the finalized version of the Speech Disorders Classification System describ...

Whole-word measures and the speech production of typically developing Dutch children.
In this study, the phonological whole-word measure Phonological Mean Length of Utterance was applied to identify stages in the phonological acquisition of Dutch children. Ninety spontaneous speech samples of 47 typically developing Dutch children from a previous study were examined. Samples were distributed across nine age groups ranging between 1;3-4;0 years. Across all age groups, PMLU of word productions increased significantly with the largest increase found below age 2;0 years. PMLU of the target words showed no significant increase across age groups. Outcomes suggest that the phonological whole-word measure PMLU can ...
