Response to Music-Mediated Intervention in Autistic Children with Limited Spoken Language Ability.

Purpose: Autistic children with limited spoken language ability (LSLA) often do not respond to traditional interventions, reducing their social inclusion. It is essential to identify effective interventions, and sensitive measures to track their intervention response.

Methods: Using data from an RCT comparing music-mediated and play-based interventions, we investigated the impact of spoken language ability on outcomes, and measured response to intervention through natural language sample measures.

Implications of video chat use for young children's learning and social-emotional development: Learning words, taking turns, and fostering familial relationships.

Parents of young children use video chat differently than other screen media, paralleling expert recommendations (e.g., American Academy of Pediatrics Council on Communications and Media, 2016), which suggest that video chat, unlike other screen media, is acceptable for use by children under 18 months.

Joint engagement and movement: Active ingredients of a music-based intervention with school-age children with autism.

Background: The effectiveness of music-based interventions (MI) in autism has been attested for decades. Yet, there has been little empirical investigation of the active ingredients, or processes involved in music-based interventions that differentiate them from other approaches.

Objectives: Here, we examined whether two processes, joint engagement and movement, which have previously been studied in isolation, contribute as important active ingredients for the efficacy of music-based interventions.

Towards greater transparency in neurodevelopmental disorders research: use of a proposed workflow and propensity scores to facilitate selection of matched groups.

Background: Matching is one commonly utilized method in quasi-experimental designs involving individuals with neurodevelopmental disorders (NDD). This method ensures two or more groups (e.g.

Brief Report: Vocabulary and Grammatical Skills of Bilingual Children with Autism Spectrum Disorders at School Age.

We examined the lexical and grammatical skills of monolingual and bilingual school-age children with autism spectrum disorders (ASD). Thirteen monolingual and thirteen bilingual children with ASD without intellectual disability, were compared on standardized measures of vocabulary and morphology. Findings revealed that bilingual children performed in the average monolingual range on a standardized receptive vocabulary test and slightly below the average range on a standardized morphological task in their dominant language.

Bilingual children with autism spectrum disorders: The impact of amount of language exposure on vocabulary and morphological skills at school age.

Studies of bilingual children with Autism Spectrum Disorders (ASD) have focused on early language development using parent report measures. However, the effect of bilingual exposure on more complex linguistic abilities is unknown. In the current study, we examined the impact of amount of language exposure on vocabulary and morphological skills in school-aged children with ASD who did not have intellectual disability.

Results of a RCT on a Transition Support Program for Adults with ASD: Effects on Self-Determination and Quality of Life.

Few evidence-based services exist for people with Autism Spectrum Disorder (ASD) as they transition into adulthood, particularly those that foster appreciation of one's own goals and strengths. We developed a transition service for adults with ASD (without Intellectual Disability), and conducted a randomized controlled trial (RCT) focusing on self-report of Quality of Life and Self-Determination outcomes. Thirty participants aged 18-29 were randomized to immediate or delayed intervention, with 26 participants analyzed after 4 were lost to follow-up.

Music improves social communication and auditory-motor connectivity in children with autism.

Music has been identified as a strength in people with Autism Spectrum Disorder; however, there is currently no neuroscientific evidence supporting its benefits. Given its universal appeal, intrinsic reward value and ability to modify brain and behaviour, music may be a potential therapeutic aid in autism. Here we evaluated the neurobehavioural outcomes of a music intervention, compared to a non-music control intervention, on social communication and brain connectivity in school-age children (ISRCTN26821793).

Can Bilingualism Mitigate Set-Shifting Difficulties in Children With Autism Spectrum Disorders?

This study investigated the effects of bilingualism on set-shifting and working memory in children with autism spectrum disorders (ASD). Bilinguals with ASD were predicted to display a specific bilingual advantage in set-shifting, but not working memory, relative to monolinguals with ASD. Forty 6- to 9-year-old children participated (20 ASD, 20 typically-developing).

Intact non-word repetition and similar error patterns in language-matched children with autism spectrum disorders: A pilot study.

Purpose: We investigated whether enhanced auditory short-term memory may contribute to the learning of novel word forms in children with Autism Spectrum Disorder. We also evaluated whether delayed but qualitatively normal, versus atypical, cognitive processes underlie non-word repetition in this population via a detailed error analysis.

Method: English-speaking children with Autism Spectrum Disorder (who had significant language delay) and typically-developing children matched pairwise on language ability were compared on the Syllable Repetition Task (Shriberg et al.

Reduced sensitivity to context in language comprehension: A characteristic of Autism Spectrum Disorders or of poor structural language ability?

We present two experiments examining the universality and uniqueness of reduced context sensitivity in language processing in Autism Spectrum Disorders (ASD), as proposed by the Weak Central Coherence account (Happé & Frith, 2006, Journal of Autism and Developmental Disorders, 36(1), 25). That is, do all children with ASD exhibit decreased context sensitivity, and is this characteristic specific to ASD versus other neurodevelopmental conditions? Experiment 1, conducted in English, was a comparison of children with ASD with normal language and their typically-developing peers on a picture selection task where interpretation of sentential context was required to identify homonyms. Contrary to the predictions of Weak Central Coherence, the ASD-normal language group exhibited no difficulty on this task.

Global Similarities and Multifaceted Differences in the Production of Partner-Specific Referential Pacts by Adults with Autism Spectrum Disorders.

Over repeated reference conversational partners tend to converge on preferred terms or referential pacts. Autism spectrum disorders (ASD) are characterized by pragmatic difficulties that are best captured by less structured tasks. To this end we tested adults with ASD who did not have language or intellectual impairments, and neurotypical comparison participants in a referential communication task.

Learning language in autism: maternal linguistic input contributes to later vocabulary.

It is well established that children with typical development (TYP) exposed to more maternal linguistic input develop larger vocabularies. We know relatively little about the linguistic environment available to children with autism spectrum disorders (ASD), and whether input contributes to their later vocabulary. Children with ASD or TYP and their mothers from English and French-speaking families engaged in a 10 min free-play interaction.

Brief report: Conveying subjective experience in conversation: production of mental state terms and personal narratives in individuals with high functioning autism.

Mental state terms and personal narratives are conversational devices used to communicate subjective experience in conversation. Pre-adolescents with high-functioning autism (HFA, n = 20) were compared with language-matched typically-developing peers (TYP, n = 17) on production of mental state terms (i.e.

Children's referential understanding of novel words and parent labeling behaviors: similarities across children with and without autism spectrum disorders.

This study examined two facets of the use of social cues for early word learning in parent-child dyads, where children had an Autism Spectrum Disorder (ASD) or were typically developing. In Experiment 1, we investigated word learning and generalization by children with ASD (age range: 3;01-6;02) and typically developing children (age range: 1;02-4;09) who were matched on language ability. In Experiment 2, we examined verbal and non-verbal parental labeling behaviors.

Acoustic and perceptual measurement of expressive prosody in high-functioning autism: increased pitch range and what it means to listeners.

Are there consistent markers of atypical prosody in speakers with high functioning autism (HFA) compared to typically-developing speakers? We examined: (1) acoustic measurements of pitch range, mean pitch and speech rate in conversation, (2) perceptual ratings of conversation for these features and overall prosody, and (3) acoustic measurements of speech from a structured task. Increased pitch range was found in speakers with HFA during both conversation and structured communication. In global ratings listeners rated speakers with HFA as having atypical prosody.

Intact and impaired mechanisms of action understanding in autism.

Typically developing children understand and predict others' behavior by extracting and processing relevant information such as the logic of their actions within the situational constraints and the intentions conveyed by their gaze direction and emotional expressions. Children with autism have difficulties understanding and predicting others' actions. With the use of eye tracking and behavioral measures, we investigated action understanding mechanisms used by 18 children with autism and a well-matched group of 18 typically developing children.

How does the topic of conversation affect verbal exchange and eye gaze? A comparison between typical development and high-functioning autism.

Conversation is a primary area of difficulty for individuals with high-functioning autism (HFA) although they have unimpaired formal language abilities. This likely stems from the unstructured nature of face-to-face conversation as well as the need to coordinate other modes of communication (e.g.

Adaptation of object descriptions to a partner under increasing communicative demands: a comparison of children with and without autism.

This study compared the object descriptions of school-age children with high-functioning autism (HFA) with those of a matched group of typically developing children. Descriptions were elicited in a referential communication task where shared information was manipulated, and in a guessing game where clues had to be provided about the identity of an object that was hidden from the addressee. Across these tasks, increasingly complex levels of audience design were assessed: (1) the ability to give adequate descriptions from one's own perspective, (2) the ability to adjust descriptions to an addressee's perspective when this differs from one's own, and (3) the ability to provide indirect yet identifying descriptions in a situation where explicit labeling is inappropriate.

What do children with autism attend to during imitation tasks?

Individuals with autism show a complex profile of differences in imitative ability, including a general deficit in precision of imitating another's actions and special difficulty in imitating nonmeaningful gestures relative to meaningful actions on objects. Given that they also show atypical patterns of visual attention when observing social stimuli, we investigated whether possible differences in visual attention when observing an action to be imitated may contribute to imitative difficulties in autism in both nonmeaningful gestures and meaningful actions on objects. Results indicated that (a) a group of 18 high-functioning 8- to 15-year-olds with autistic disorder, in comparison with a matched group of 13 typically developing children, showed similar patterns of visual attention to the demonstrator's action but decreased attention to his face when observing a model to be imitated; (b) nonmeaningful gestures and meaningful actions on objects triggered distinct visual attention patterns that did not differ between groups; (c) the autism group demonstrated reduced imitative precision for both types of imitation; and (d) duration of visual attention to the demonstrator's action was related to imitation precision for nonmeaningful gestures in the autism group.

Objective: To assess the sensitivity and specificity of decreased response to name at age 12 months as a screen for autism spectrum disorders (ASD) and other developmental delays.

Design: Prospective, longitudinal design studying infants at risk for ASD.

Setting: Research laboratory at university medical center.

Evidence of perspective-taking constraints in children's on-line reference resolution.

Young children's communication has often been characterized as egocentric. Some researchers claim that the processing of language involves an initial stage that relies on egocentric heuristics, even in adults. Such an account, combined with general developmental difficulties with late-stage processes, could provide an explanation for much of children's egocentric communication.
