Index. décimale : PER Périodiques Résumé : Although pragmatic speech impairments have been found across the autism spectrum, how these manifest in minimally verbal (MV) individuals with autism spectrum disorder (ASD) has not been studied. We compared the pragmatic speech profiles of MV (n?=?50) and verbally fluent (VF) individuals with ASD (n?=?50; 6-21 years-old) based on natural language sampling during the Autism Diagnostic Observation Schedule-2. MV individuals with ASD primarily used their speech to agree/acknowledge/disagree, respond to a question, and request. In contrast, the primary pragmatic function used by VF individuals was commenting. Out of the total non-echolalic speech, groups did not differ proportionally in labeling and response to questions. Findings highlight the importance of investigating multiple aspects of pragmatic communication across different conversational partners and contexts.

Eliciting Language Samples for Analysis (ELSA): A New Protocol for Assessing Expressive Language and Communication in Autism / Mihaela D. BAROKOVA in Autism Research, 14-1 (January 2021)

Currently, there are no protocols for collecting such samples that cover a wide range of ages or language abilities, particularly for children/adolescents who have very limited spoken language. We introduce a new protocol for collecting language samples, eliciting language samples for analysis (ELSA), and a novel approach for deriving basic measures of verbal communicative competence from it that bypasses the need for time-consuming transcription. Study 1 presents ELSA-adolescents (ELSA-A), designed for minimally and low-verbal older children/adolescents with ASD. The protocol successfully engaged and elicited speech from 46 participants across a wide range of ages (6;6-19;7) with samples averaging 20-25?min. The collected samples were segmented into speaker utterances (examiner and participant) using real-time coding as one is listening to the audio recording and two measures were derived: frequency of utterances and conversational turns per minute. These measures were shown to be reliable and valid. For Study 2, ELSA was adapted for younger children (ELSA-Toddler [ELSA-T]) with samples averaging 29?min from 19 toddlers (2;8-4;10?years) with ASD. Again, measures of frequency of utterances and conversational turns derived from ELSA-T were shown to have strong psychometric properties. In Study 3, we found that ELSA-A and ELSA-T were equivalent in eliciting language from 17 children with ASD (ages: 4;0-6;8), demonstrating their suitability for deriving robust objective assessments of expressive language that could be used to track change in ability over time. We introduce a new protocol for collecting expressive language samples, ELSA, that can be used with a wide age range, from toddlers (ELSA-T) to older adolescents (ELSA-A) with ASD who have minimal or low-verbal abilities. The measures of language and communication derived from them, frequency of utterances, and conversational turns per minute, using real-time coding methods, can be used to characterize ability and chart change in intervention research.

Frequency and characteristics of echoes and self-repetitions in minimally verbal and verbally fluent autistic individuals / Pauline MAES in Autism & Developmental Language Impairments, 9 (January-December 2024)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 9 (January-December 2024) Titre : Frequency and characteristics of echoes and self-repetitions in minimally verbal and verbally fluent autistic individuals Type de document : Texte imprimé et/ou numérique Auteurs : Pauline MAES, Auteur ; Chelsea LA VALLE, Auteur ; Helen TAGER-FLUSBERG, Auteur Langues : Anglais (eng) Mots-clés : Echolalia  self-repetition  nongenerative speech  minimally verbal  autism Index. décimale : PER Périodiques Résumé : Background and aims Nongenerative speech is the rote repetition of words or phrases heard from others or oneself. The most common manifestations of nongenerative speech are immediate and delayed echolalia, which are a well-attested clinical feature and a salient aspect of atypical language use in autism. However, there are no current estimates of the frequency of nongenerative speech, and the individual characteristics associated with nongenerative speech use in individuals across the autistic spectrum are poorly understood. In this study, we aim to measure and characterize spontaneous and nongenerative speech use in minimally verbal and verbally fluent autistic children and adolescents. Methods Participants were 50 minimally verbal and 50 verbally fluent autistic individuals aged 6 to 21 years. Spontaneous and nongenerative speech samples were derived from SALT transcripts of ADOS-2 assessments. Participants' intelligible speech utterances were categorized as spontaneous or nongenerative. Spontaneous versus nongenerative utterances were compared between language subgroups on frequency of use and linguistic structure. Associations between nongenerative speech use and a series of individual characteristics (ADOS-2 subscale scores, nonverbal IQ, receptive vocabulary, and chronological age) were investigated over the whole sample and for each language subgroup independently. Results Almost all participants produced some nongenerative speech. Minimally verbal individuals produced significantly more nongenerative than spontaneous utterances, and more nongenerative utterances compared to verbally fluent individuals. Verbally fluent individuals produced limited rates of nongenerative utterances, in comparison to their much higher rates of spontaneous utterances. Across the sample, nongenerative utterance rates were associated with nonverbal IQ and receptive vocabulary, but not separately for the two language subgroups. In verbally fluent individuals, only age was significantly inversely associated with nongenerative speech use such that older individuals produced fewer nongenerative utterances. In minimally verbal individuals, there were no associations between any of the individual characteristics and nongenerative speech use. In terms of linguistic structure, the lexical diversity of nongenerative and spontaneous utterances of both language subgroups was comparable. Morphosyntactic complexity was higher for spontaneous compared to nongenerative utterances in verbally fluent individuals, while no differences emerged between the two utterance types in minimally verbal individuals. Conclusions Nongenerative speech presents differently in minimally verbal and verbally fluent autistic individuals. Although present in verbally fluent individuals, nongenerative speech appears to be a major feature of spoken language in minimally verbal children and adolescents. Implications Our results advocate for more research on the expressive language profiles of autistic children and adolescents who remain minimally verbal and for further investigations of nongenerative speech, which is usually excluded from language samples. Given its prevalence in the spoken language of minimally verbal individuals, nongenerative speech could be used as a way to engage in and maintain communication with this subgroup of autistic individuals.
