Conversational behaviors in youth with high-functioning ASD and Asperger syndrome

Conversational topic maintenance and related cognitive abilities in autistic versus neurotypical children

LAY ABSTRACT

Children who struggle to maintain conversation with peers often have fewer friends and lower popularity ratings, which can affect wellbeing. Verbal social communication more broadly is linked to both behavioural difficulties and emotional problems. We carried out three studies to examine children's ability to provide responses which keep a back and forth conversation going. The first study found that while autistic children had on average greater difficulties than their neurotypical peers with certain aspects of conversation topic maintenance, for other aspects the autistic group showed considerable strengths. Both studies 2 (neurotypical children) and 3 (autistic children) found relationships between, on the one hand, conversational ability, and on the other, the ability to consider another's viewpoint and the ability to maintain and update information in short term memory. We suggest support for social conversation skills should be part of mainstream classroom curricula for autistic and neurotypical children alike.

The use of formal language as a strong sign of verbal autistic children in diglossic communities: The case of Arabic

The current study aimed to investigate whether the use of formal language (Modern Standard Arabic [MSA]) by young children in diglossic Arab communities offers diagnostic insights, especially for verbal autistic children and to further explore this phenomenon. We used a cohort study design, with 4-6-year-old fluent first language Arabic-speaking children attending Arabic Kindergartens in two representative Kuwait governates. Reported cases for MSA use were assessed via a computer-based structured language test and corroborated cases were further assessed for exposure to sources of MSA, verbal IQ, temperamental characteristics, and autism spectrum disorder (ASD). Four children from the same class without developmental difficulties were selected for each MSA user as control group. The frequency of MSA use among verbal pre-schoolers was 0.46%. Use of MSA did not correlate with parents' education, amount of exposure to MSA, verbal IQ, but with severity of ASD. Predicted probability of ASD in the presence of MSA was 0.86. Executive functions of ASD-MSA users were similar to those of the control group and significantly higher than unselected autistic peers in the literature. The use of MSA has the potential to serve as a strong sign for the diagnosis of verbal autistic children, often missed or delayed in being diagnosed. We also discuss strategies via which language is acquired in ASD.

Supporting the Conversational Behavior of Adolescents with Autism Spectrum Disorders with Self-Monitoring and a Video-Based Supplement

Individuals with autism spectrum disorders (ASD) might demonstrate impairments in initiating and sustaining a conversation and experience conversational challenges such as question-asking and turn-taking. Conversational skills are pivotal for the social functioning of adolescents with ASD. The current investigation aimed to extend the available information on interventions addressing the conversational needs of adolescents with ASD. The research questions were: (a) What is the effect of self-monitoring, supplemented by a video-based model on the conversational skills of adolescent students with ASD? and (b) What is the acceptability of the intervention among the participating adolescents with ASD?. Appropriate conversational behavior of three students with ASD (aged 16-18 years) was assessed using a withdrawal design, during 10-min conversation sessions. Appropriate conversational behavior was defined as a sequence of a turn-taking response (i.e., waiting quietly until the speaker finished talking), followed by a verbal utterance which included (a) making a statement or responding on topic, and/or (b) asking a contextually appropriate "wh"- question. The independent variable consisted of a primary self-monitoring procedure and a daily video-based supplement. Treatment fidelity and treatment acceptability were also assessed. The conversational behavior of all participants consistently improved under the self-monitoring intervention with the video-based supplement. Self-monitoring with a video-based supplement can effectively support the conversational behavior in adolescents with ASD. This information can guide the evaluation and planning of appropriate interventions designed to improve limited conversational behaviors of adolescents with ASD.

Developmental process of the understanding of linguistic register in children: A comparison of typically developing children, autistic children, and children with Williams syndrome

Although the developmental process of linguistic register-the appropriate manner of speech as determined by the listener and social situation-has been gradually clarified in typically developing (TD) children, research on the mechanism and developmental process of register acquisition in atypically developing children are insufficient. This study compared the developmental process of understanding linguistic register among TD children, autistic children, and those with Williams syndrome (WS), and examined the contributions of social cognition and motivation to the acquisition of linguistic register. Two experiments were designed to assess the recognition of which linguistic register to use when communicating with different listeners and of the listener's feelings according to the speakers' use of register. The results revealed that the process of understanding register-listener associations was nearly identical among all groups of children and their understanding improved with age. Conversely, their understanding of the effect of register selection on the listener's feelings varied. Importantly, as TD children mature, they become aware that adult listeners may feel negatively when spoken to in an inappropriate register, whereas autistic children and those with WS do not exhibit the same awareness. Thus, our results suggest that atypical social cognition and motivation do not disturb the understanding of register-listener associations. However, social cognition and motivation play important roles in understanding the effect of register selection on the listener's feelings. These findings provide a significant contribution to clarifying the mechanism of linguistic register acquisition.

Problems with "problem behavior": A secondary systematic review of intervention research on transition-age autistic youth

LAY ABSTRACT

In a previous study, we looked at research done on strategies to support autistic people who were between 14 and 22 years old. For this study, we looked at all of the studies in our previous study that tried to decrease or stop autistic people from doing certain things-many researchers call these things "problem behavior." There were 48 studies that tried to reduce problem behavior, and most of them used strategies like prompting and reinforcement to try get autistic people to change their behavior. We found many things wrong with these studies. Most of them did not define the group of behaviors they were trying to stop autistic people from doing. None of the studies looked at whether any side effects happened when they tried the strategy they were studying. Also, most of the studies tried to stop autistic people from doing behaviors that probably were not harmful, like stereotypic behavior. Most of the studies did not say how they decided that the behaviors they tried to stop were a problem for the autistic people in the study, and most studies did not try to figure out why the autistic people in the study did the behaviors the researchers were trying to stop them from doing.

Predicting Social Competence in Autistic and Non-Autistic Children: Effects of Prosody and the Amount of Speech Input

PURPOSE

Autistic individuals often face challenges perceiving and expressing emotions, potentially stemming from differences in speech prosody. Here we explore how autism diagnoses between groups, and measures of social competence within groups may be related to, first, children's speech characteristics (both prosodic features and amount of spontaneous speech), and second, to these two factors in mothers' speech to their children.

METHODS

Autistic (n = 21) and non-autistic (n = 18) children, aged 7-12 years, participated in a Lego-building task with their mothers, while conversational speech was recorded. Mean F0, pitch range, pitch variability, and amount of spontaneous speech were calculated for each child and their mother.

RESULTS

The results indicated no differences in speech characteristics across autistic and non-autistic children, or across their mothers, suggesting that conversational context may have large effects on whether differences between autistic and non-autistic populations are found. However, variability in social competence within the group of non-autistic children (but not within autistic children) was predictive of children's mean F0, pitch range and pitch variability. The amount of spontaneous speech produced by mothers (but not their prosody) predicted their autistic children's social competence, which may suggest a heightened impact of scaffolding for mothers of autistic children.

CONCLUSION

Together, results suggest complex interactions between context, social competence, and adaptive parenting strategies in driving prosodic differences in children's speech.

The Interactional Structure of Accounts During Small Group Discussions Among Autistic Children Receiving Special Education Support in Finland

Through a conversation analytic approach, we investigate the emergence of accounts provided by autistic children in small-group discussions. Nine Finnish children (7-10 years old) attending school with special support participated in a five-month-duration pedagogical practice purposefully designed to enhance children's participation in groups. We analyzed videos of sharing circles where children discussed their ideas and interests. Our data show three different account structures, which created different modes of children's participation and gradually changed how they positioned themselves in the group. Results show how accounts can create different focuses of attention; reveal children's reflections on what is relevant to them, and how to promote the exchange of ideas within a small group. Implications for the development of educational practices are discussed.

Effects of dialogic reading for comprehension (LuDiCa) on the social interaction of autistic adolescents and their peers

BACKGROUND

In today's contemporary world, relationships take a prominent role in the lives of adolescents. However, challenges related to mutual understanding and a lack of inclusive environments can often lead to autistic teens feeling excluded.

OBJECTIVE

In order to assess the impact of naturalistic interventions on interpersonal relationships, we conducted an experimental test utilizing Dialogic Reading for Comprehension (LuDiCa) in online reading circles with groups comprising both autistic and neurotypical adolescents. Our focus was on exploring its relevance for enhancing social interaction, particularly in terms of conversational acts, sharing experiences, initiations, and questions.

METHODS

Five autistic and five neurotypical students between 11 and 15 years old from a public school in Brasilia, Federal District, participated. We paired groups A and B (made up of trios of teenagers) and groups C and D (made up of pairs) in a multiple baseline design per reading group, in which all groups went through the baseline conditions (BL), intervention (LuDiCa) and maintenance.

RESULTS

LuDiCa increased the frequency of conversational acts of both autistic participants and neurotypical peers. In addition, the intervention favored initiations, questions, and sharing experiences, through the shared activity of reading and talking about a work of fiction. Participants rated the intervention in relation to the platform, the book, the reading facilitator, and interaction with peers. We discuss the potential of the facilitator's role in favoring interactions and the potential of LuDiCa as a joint activity for the engagement of adolescents. We also include suggestions for future research focused on the online context and discuss some limitations of the LuDiCa intervention.

CONCLUSION

In summary, our study offers initial experimental evidence demonstrating the positive impact of LuDiCa on social interaction behaviors among both autistic and neurotypical adolescents within an inclusive setting.

Is language impaired in Spanish-speaking children with autism spectrum disorder level 1?

The current diagnostic criteria for the autism spectrum disorder (ASD) include the possibility to specify concomitant language difficulties.

Purpose

Our main aim was to explore whether children with ASD-Level 1 (ASD-L1) present difficulties in the acquisition of structural language, as little work has been done in this regard so far. As a secondary aim we evaluated the degree to which the potential language impairment in ASD is directly associated with their social communication deficits or it represents a distinct deficit.

Methods

To further clarify the nature and characteristics of putative language difficulties in ASD-L1, we evaluated language skills in 89 children and preadolescents diagnosed with ASD-L1, and a group of typically developing participants (TD). All of them were between 8 and 13 years old and had similar socioeconomic backgrounds.

Results

Children with ASD-L1 obtained lower scores than those in TD group in repeating sentences, in finding the semantic relationships between words, and in applying word structure rules (morphology). Congruently, the core language standard score was lower in the ASD-L1 group, and the proportion of language delay was significantly higher in the ASD-L1 group than in the control group.

Conclusion

Language scores were associated with autistic traits; thus, language performance in ASD-L1 is closely related to autistic symptoms. These results are discussed according to the literature on linguistic deficits in ASD-L1 and their relations with phonological working memory.

Does Cognitive-Behavioral Therapy for Youth Anxiety Disorders Improve Social Functioning and Peer Relationships?

Child and adolescent anxiety disorders (ADs) contribute to impairment in social functioning and peer relationships, exacerbating anxiety and related difficulties. The extent to which the AD treatment with the strongest evidence-base, cognitive-behavioral therapy (CBT), improves social functioning and peer relationships is unclear. In this article, we report results of the first systematic narrative review of this topic. Randomized clinical trials of CBT for child and/or adolescent ADs were included if they used at least one measure of social functioning or peer relationships as a treatment outcome. Sixteen studies met our inclusion criteria. From each study, we extracted the sample characteristics, treatment arms, social and/or peer outcome measures, and statistical findings. Results show that social functioning and/or peer relationships improved over time in the majority of studies, highlighting an important aspect of treatment efficacy beyond anxiety reduction. There were also several treatment-specific effects, but considerable variability across studies' samples, methods, and findings, makes it difficult to draw firm conclusions about which specific treatments improve specific outcomes. We recommend next steps for research to reconcile these findings, including improved operationalization and standardization of social and peer outcomes, and research on treatment specificity and mechanisms.

Neural Processing of Speech Sounds in ASD and First-Degree Relatives

Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal encoding of speech sounds in both groups. The ASD group further demonstrated less robust neural representation of spectral properties of speech sounds. Associations between neural processing of speech sounds and language-related abilities were evident in both groups. Parent-child associations were also detected in neural pitch processing. Together, results suggest that atypical neural processing of speech sounds is a heritable ingredient contributing to the ASD language phenotype.

Theory of mind in naturalistic conversations between autistic and typically developing children and adolescents

LAY ABSTRACT

Conversation is a key part of everyday social interactions. Previous studies have suggested that conversational skills are related to theory of mind, the ability to think about other people's mental states, such as beliefs, knowledge, and emotions. Both theory of mind and conversation are common areas of difficulty for autistic people, yet few studies have investigated how people, including autistic people, use theory of mind during conversation. We developed a new way of measuring cToM using two rating scales: cToM Positive captures behaviors that show consideration of a conversation partner's mental states, such as referring to their thoughts or feelings, whereas cToM Negative captures behaviors that show a lack of theory of mind through violations of neurotypical conversational norms, such as providing too much, too little, or irrelevant information. We measured cToM in 50 pairs of autistic and typically developing children (ages 8-16 years) during 5-min "getting to know you" conversations. Compared to typically developing children, autistic children displayed more frequent cToM Negative behaviors but very similar rates of cToM Positive behaviors. Across both groups, cToM Negative (but not Positive) ratings were related to difficulties in recognizing emotions from facial expressions and a lower tendency to talk about others' mental states spontaneously (i.e., without being instructed to do so), which suggests that both abilities are important for theory of mind in conversation. Altogether, this study highlights both strengths and difficulties among autistic individuals, and it suggests possible avenues for further research and for improving conversational skills.

The development of the conversation skills assessment tool

Background and aims

Having a conversation with someone or even more within a group of people is complex. We are never taught at school how to do it, which implies we consider having a conversation as something simple and straightforward. Instead, we just learn from observing others. Some people are great conversationalists - it comes naturally to them - while others struggle. Some people may not fully understand how the process works, how turn-taking happens, don't understand visual cues such as body language and facial expressions, and fail to comprehend that some topics may be appropriate or inappropriate. This can be the case for both neurotypical and neurodivergent people. The Conversation skills Assessment Tool has been developed in this first instance to help in assessing and examining conversation skills in an intervention with young autistic adults on a virtual platform (a virtual world). This paper will present the evolution of the new measure through the exploratory phase, the development phase and finally a detailed account of the inter-rater reliability process.

Methods

The intervention associated with this study was carried out though a multiple baseline design with 3 autistic participants (in their early 20 s) and took place over 4 phases (15-17 sessions). The sessions involved semi-structured conversations in face-to-face (phases 1 and 4) and virtual (phases 2 and 3) settings and were videotaped with the participants' consent. Twelve of those were used by this study in the development process through iterative inter-rater reliability stages between two coding teams.

Results

Evaluation of the Conversation skills Assessment Tool tool revealed the potential benefit of implementing interventions with measures that more objectively and concretely (e.g., by noting frequencies) assess observable behaviours that are associated with having positive conversations with others. Beyond this, it is anticipated that Conversation skills Assessment Tool can emerge as a tool capable of not only accounting for the environment an interaction takes place in (e.g., professional, casual), but also offers beneficial feedback for both autistic students and other populations (e.g., young children, English language learners).

Conclusions

This measure has the potential to offer quantifiable and trackable guidance to people who have difficulties conversing. The authors do not wish to perpetuate an ableist social construct of what is a 'good' conversation, nor do they suggest that conversation skills training is useful solely for people with communication and/or socialization difficulties. Rather, they hope that Conversation skills Assessment Tool can be adopted more broadly to give both neurotypical and neurodivergent people a better understanding of how to communicate more effectively with others, while also becoming more aware and accepting of differing conversational styles.

Implications

Because of its ability to track (or self-monitor) one's development of conversational skills over time, Conversation skills Assessment Tool could serve as an educative tool in early childhood education. It can be used by occupational/speech therapists and other professionals and also used to self-monitor one's development of conversational skills. Conversation skills Assessment Tool was developed to assess conversation skills on a one-to-one basis; therefore, another iteration of Conversation skills Assessment Tool would have to look at group conversations.

Linking ADHD and ASD Symptomatology with Social Impairment: The Role of Emotion Dysregulation

Children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often experience social impairments. These children also frequently struggle with emotion regulation, and extant literature suggests that emotion dysregulation predicts social impairment in both clinical and neurotypical populations. However, the evidence base linking ADHD/ASD with social impairment comes primarily from samples meeting full diagnostic criteria for ADHD and/or ASD despite evidence that both syndromes reflect extreme ends of natural continuums that are normally distributed across the general population. To our knowledge, the present study is the first to concurrently examine unique and overlapping relations among ADHD/ASD symptoms, emotion regulation, and social difficulties using multi-informant measures (parent, teacher) with a clinically-evaluated sample of 108 children ages 8-13 (40 girls; 66% White/Non-Hispanic) with and without clinically-elevated ASD and ADHD symptoms and other common clinical disorders. Bias-corrected, bootstrapped conditional effects modeling revealed that ADHD-inattentive (β=-0.23) and ASD-social communication (β=-0.20) symptoms predicted social impairment directly, whereas ADHD-hyperactive/impulsive (β=-0.06) and ASD-restricted/repetitive behavior/interests (β=-0.06) symptoms predicted social impairment only via their shared associations with emotion dysregulation. Sensitivity analyses revealed that most relations were robust to control for item overlap across measures. In contrast, only the ADHD-inattention/social impairment link was robust to control for mono-informant bias, highlighting the importance of multi-informant methods and the potential for different determinants of social functioning across settings. Overall, this study implicates emotion regulation skills and all four ADHD/ASD symptom clusters as potential influences on children's social functioning, albeit with a more nuanced and potentially setting-specific pattern than suggested by prior work.

Evaluating the Performance of Transformer-based Language Models for Neuroatypical Language

Difficulties with social aspects of language are among the hallmarks of autism spectrum disorder (ASD). These communication differences are thought to contribute to the challenges that adults with ASD experience when seeking employment, underscoring the need for interventions that focus on improving areas of weakness in pragmatic and social language. In this paper, we describe a transformer-based framework for identifying linguistic features associated with social aspects of communication using a corpus of conversations between adults with and without ASD and neurotypical conversational partners produced while engaging in collaborative tasks. While our framework yields strong accuracy overall, performance is significantly worse for the language of participants with ASD, suggesting that they use a more diverse set of strategies for some social linguistic functions. These results, while showing promise for the development of automated language analysis tools to support targeted language interventions for ASD, also reveal weaknesses in the ability of large contextualized language models to model neuroatypical language.

Pretense Awareness Context and Autism: Insights from Conversation Analysis

Utilizing approaches from Conversation Analysis and Interactional Sociolinguistics, this study investigates linguistic resources related to discourse while playing a tabletop roleplaying game, with particular investigation around the discourse of individuals with autism spectrum disorder. The study examines interactions as they take place across three frames that are associated with interaction in this community of practice: the primary frame, the metagaming frame, and the character frame. The study found that the participants with autism frequently violated the stable pretense awareness context that persists across these frames in tabletop roleplaying game discourse. This research has implications for social skills training methods and psychological models of autism symptomatology.

"Um" and "Uh" Usage Patterns in Children with Autism: Associations with Measures of Structural and Pragmatic Language Ability

Pragmatic language difficulties, including unusual filler usage, are common among children with Autism Spectrum Disorder (ASD). This study investigated "um" and "uh" usage in children with ASD and typically developing (TD) controls. We analyzed transcribed Autism Diagnostic Observation Schedule (ADOS) sessions for 182 children (117 ASD, 65 TD), aged 4 to 15. Although the groups did not differ in "uh" usage, the ASD group used fewer "ums" than the TD group. This held true after controlling for age, sex, and IQ. Within ASD, social affect and pragmatic language scores did not predict filler usage; however, structural language scores predicted "um" usage. Lower "um" rates among children with ASD may reflect problems with planning or production rather than pragmatic language.

Using a Brief Intervention to Improve Partner-Focused Conversation in Adolescents with Autism

Individuals on the autism spectrum often experience pragmatic social conversation difficulties that include showing interest in their conversational partners. This may become particularly evident during adolescence when conversation with peers is the primary medium for social interaction. This study used a multiple baseline design across participants to investigate the effects of a brief intervention package on the partner-focused conversation of three adolescents with autism. Results showed increased partner-focused questions and comments for all participants. Social validity assessments indicated that the intervention led to meaningful improvements in peer conversations.

Conventions for unconventional language: Revisiting a framework for spoken language features in autism

Background and aims

Autism has long been characterized by a range of spoken language features, including, for instance: the tendency to repeat words and phrases, the use of invented words, and "pedantic" language. These observations have been the source of considerable disagreement in both the theoretical and applied realms. Despite persistent professional interest in these language features, there has been little consensus around terminology, definitions and developmental/clinical interpretation.

Main contribution

This review paper updates and expands an existing framework for unconventional language in autism to include a broader range of non-generative (echolalia and self-repetition) and generative (idiosyncratic phrases, neologisms and pedantic language) features often observed in the language of individuals on the autism spectrum. For each aspect of the framework, we review the various definitions and measurement approaches, and we provide a summary of individual and contextual correlates. We also propose some transitional language features that may bridge non-generative and generative domains (e.g., mitigated echolalia and gestalt language).

Conclusions

This updated framework offers a unified taxonomy and nomenclature that can facilitate further investigation and interpretation of unconventional language in autism.

Implications

There are important implications of this work for our understanding of the complex interplay between autism and language development. Equally important are the clinical ramifications that will guide evidence-based practice in assessment and intervention for individuals on the autism spectrum.

Development and validation of the conversation questionnaire: A psychometric measure of communication challenges generated from the self-reports of autistic people

Existing measures of communication challenges in autism are based on diagnostic criteria and research/clinical observations of autistic people, rather than what autistic people themselves identify as difficulties. In this study, the Conversation Questionnaire (CQ) was developed based on community engagement with autistic people to identify what they find challenging about conversation. This new tool was then administered online to autistic, dyslexic and neurotypical people (N = 312) in a validation phase of the study. Item-response theory modelling indicated that a two-dimensional structure accounted for response patterns. These dimensions reflected difficulties knowing what to say (15 items) and engaging in behaviours possibly disruptive to neurotypical conversation (21 items). The dimensions showed good internal consistency and convergent and discriminant validity, and could distinguish between autistic and neurotypical people (d = 1.59 and d = 2.07 respectively). The CQ might help contribute to diagnostic assessment for autism in adults as part of a holistic assessment. The questionnaire might also be useful with other neurodiverse groups, and provide a tool for clinicians and researchers to identify individuals' strengths and difficulties in conversation (e.g., as part of interventions in speech and language therapy).

Using Peer Supports to Encourage Adolescents With Autism Spectrum Disorder to Show Interest in Their Conversation Partners

PURPOSE

This study was conducted to evaluate the effects of a multicomponent peer-mediated intervention (PMI) on teaching adolescents with autism spectrum disorder (ASD) how to show interest in peer conversation partners by asking partner-focused questions about the person, their interests, or their experiences and by making partner-focused comments that positively affirm peer statements or express concern.

METHOD

A multiple-baseline design across three verbally fluent high school students with ASD was used to assess the effects of the PMI, which involved training peers (n = 10) to support conversation and the students' use of target skills, and training the students to use partner-focused skills with the aid of a self-reflection cue sheet during conversation with trained peers in a high school cafeteria. Ten-minute samples of student-peer conversations were transcribed and analyzed. Generalization with untrained peers was assessed.

RESULTS

The PMI was highly effective in increasing all students' use of partner-focused skills. Gains were maintained by two students in a return-to-baseline condition. Generalization was evident for all students with varied results. Peers and students with ASD perceived the intervention to be beneficial.

CONCLUSIONS

This study adds to the limited research showing that PMI can be used in high school settings to improve target conversational skills and provides preliminary evidence that PMI can successfully address an underresearched pragmatic language difficulty (i.e., introducing and maintaining topics of conversation of relevance and interest to conversation partners) common among adolescents with ASD. These findings invite replication to extend generality and assess the impact of the intervention on peer relationships. Supplemental Material https://doi.org/10.23641/asha.16915663.

Assessment and Treatment of Prosody Behavior in Individuals with Level 1 Autism: A Review and Call for Research

Differences in prosody behavior between individuals with autism spectrum disorder (ASD) and their typically developing peers have been considered a central feature of ASD since the earliest clinical descriptions of the disorder (e.g., Kanner, 1943/1973). Prosody includes pitch and volume among other dimensions of vocal-verbal behavior that discriminate responses of the listener; thus, people with ASD whose prosody has confusing or off-putting effects may have fewer social opportunities at work, at school, or in the community. The purpose of this review is to examine the state of the literature intervening on prosody with individuals with ASD and to provide recommendations for researchers who are interested in contributing to the scientific understanding of prosody.

Veritable Untruths: Autistic Traits and the Processing of Deception

How do we decide whether a statement is literally true? Here, we contrast participants’ eventual evaluations of a speaker’s meaning with the real-time processes of comprehension. We record participants’ eye movements as they respond to potentially misleading instructions to click on one of two objects which might be concealing treasure (the treasure is behind thee, uh, hat). Participants are less likely to click on the named object when the instructions are disfluent. However, when hearing disfluent utterances, a tendency to fixate the named object early increases with participants’ autism quotient scores. This suggests that, even where utterances are equivalently understood, the processes by which interpretations are achieved vary across individuals.

The value of employment support services for adults on the autism spectrum and/or with intellectual disabilities: Employee, employer, and job coach perspectives

BACKGROUND: Employment rates among individuals on the autism spectrum or with intellectual disabilities (ID) remain extremely low. Although job coaching services have contributed to successful employment for these individuals, few studies have examined the importance of such support, and even fewer have explored which services are valued most by stakeholders. OBJECTIVE: We examined the importance of employment support services through employee, employer, and job coach perspectives, and employee and employer satisfaction of job coach support. METHODS: A multiple-case study was designed with a community organization providing employment support to individuals on the autism spectrum or with ID, and their employers. Nine employee-employer-job coach triads evaluated the importance of specific services and rated their satisfaction with the job coach support. RESULTS: Services were rated as important, however, some discrepancies were observed between the groups in their ratings of services (e.g., soliciting regular feedback about the employee’s performance). Satisfaction was high for employees and employers; both groups indicated that they would recommend these services. CONCLUSIONS: Job coach support was highly valued by all groups, underscoring the need for these services to be widely available, and suggesting that this support may serve as a critical factor in improving employment outcomes among this population.

Working on Cognitive Functions in a Fully Digitalized Multisensory Interactive Room: A New Approach for Intervention in Autism Spectrum Disorders

The feasibility of working on cognitive functions with children and adults with Autism Spectrum Disorders (ASD) inside Multisensory Interactive Rooms (MIRs) has been poorly investigated, even if sensory atypicalities are common in ASD and usual intervention rooms could represent a challenging sensory setting for patients with ASD. We hypothesized that the possibility to calibrate the sensory stimulation offered by this type of environment, able to promote a positive emotional state in patients with ASD, can consequently favor the interaction with the therapist and the motivation towards activities targeting cognitive functions. High- and low-functioning children and low-functioning adolescents/adults underwent five sessions in a fully digitalized MIR, working on sustained attention, selective attention, association, single inhibition, receptive communication, verbalization, and turn. We developed specific protocols calibrated for sensory stimulation and difficulty level based on the characteristics of the participants. We found statistically significant improvements in all functions, except association, in the children's group. Therefore, a fully digitalized MIR seems suitable for intervention on cognitive functions in ASDs, but further investigations are needed to better address possible differences related to age and functioning level.

"Two Friends Spending Time Together": The Impact of Video Visual Scene Displays on Peer Social Interaction for Adolescents With Autism Spectrum Disorder

Purpose Social interaction poses many challenges for adolescents with autism spectrum disorder (ASD) and complex communication needs. The purpose of this study was to investigate the impact of video visual scene displays (video VSDs) on communication during interactions between adolescents with ASD and peer partners. Method This study used an across-participant multiple-baseline single-case experimental design. Four adolescents with ASD and complex communication needs were taught to use video VSDs, presented on a tablet-based app, during social interactions with peer partners in a high school setting. The video VSDs used during the interactions were selected (and programmed with vocabulary) based on the interests of the adolescent with ASD and their peer partner. Results Following the introduction of the video VSD intervention, all four adolescents with ASD demonstrated an increase in communicative turns compared to baseline (Tau-U= 1.0, 95% CI [0.56, 1]), and all four increased in modes of communication used. Increased use of speech also was observed for the three participants who made use of speech prior to the intervention. All participants with ASD (and their peer partners) expressed an interest in continued use of the video VSD app to support social interaction. Conclusion The use of video VSDs may be a viable option to increase the participation and communication of adolescents with ASD during social interactions with peer partners.

An artificial intelligence approach for selecting effective teacher communication strategies in autism education

Effective inclusive education is key in promoting the long-term outcomes of children with autism spectrum conditions (ASC). However, no concrete consensus exists to guide teacher-student interactions in the classroom. In this work, we explore the potential of artificial intelligence as an approach in autism education to assist teachers in effective practice in developing social and educational outcomes for children with ASC. We form a protocol to systematically capture such interactions, and conduct a statistical analysis to uncover basic patterns in the collected observations, including the longer-term effect of specific teacher communication strategies on student response. In addition, we deploy machine learning techniques to predict student response given the form of communication used by teachers under specific classroom conditions and in relation to specified student attributes. Our analysis, drawn on a sample of 5460 coded interactions between teachers and seven students, sheds light on the varying effectiveness of different communication strategies and demonstrates the potential of this approach in making a contribution to autism education.

Temporal Coordination and Prosodic Structure in Autism Spectrum Disorder: Timing Across Speech and Non-speech Motor Domains

Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and normal nonverbal IQ and matched controls. Results indicate similar group results for prosodic grouping patterns, but significant differences in relative timing and longer syllable durations at phrase ends for the ASD group. Variability on the speech task was significantly correlated with variability on the drumming task, consistent with the view that impairment in both speech and non-speech motor domains can be linked with deficits in temporal processing.

Capacity of the CCC-2 to Discriminate ASD from Other Neurodevelopmental Disorders

The Children’s Communication Checklist (CCC-2) has demonstrated its usefulness as an instrument to assess discrepancies between the use of structural dimensions of language and the pragmatic and sociointeractive uses of language. The aims of the present paper are: (1) to test the capacity of the Galician adaptation of the CCC-2 to discriminate the linguistic profiles of children with different disorders and (2) to test whether the capacity of the CCC-2 to discriminate the linguistic abilities of children with different disorders is the same at different ages: earlier development and later development. The sample is of 117 children previously diagnosed with different disorders: autism spectrum disorder (ASD), developmental language disorder (DLD), attention deficit with hyperactivity disorder (ADHD), Down syndrome children (DS) and typically developing children (TD). The children were divided into two different age groups: from 4 to 6 and from 7 to 16 years of age. The results indicate that the Galician CCC-2 (1) accurately identified children with and without communicative impairments, (2) distinguished between profiles with a predominance of pragmatic (ASD and ADHD) and structural disorders (DS and DLD) and (3) distinguished between different profiles of pragmatic impairment. The CCC-2 equally identified these profiles at both earlier and later ages. The Galician CCC-2 seems to be a useful instrument for differentiating among different clinical groups and for assessing pragmatic disorders from an early age, which can be valuable for planning early intervention.

In their own words: The impact of subtle language and communication difficulties as described by autistic girls and boys without intellectual disability

LAY ABSTRACT

Subtle language and communication difficulties are experienced by many autistic individuals even when they do not have additional learning disabilities. These difficulties may affect a person's day-to-day living, social relationships and emotional well-being. However, currently, there is not much research into this topic. To date, no one has asked autistic children about their own language and communication difficulties or how they feel it affects them. Asking the children could provide valuable new insights. In this study, 12 autistic children (9-14 years), without learning disability, were interviewed on this topic. We developed interview questions, resources and interview procedures with the support of the autistic community. We also worked with an autistic researcher to analyse our results. We aimed to get the most genuine report of the autistic child's experiences. Our results showed that the children could give detailed insight into their language and communication difficulties if they were given the right support. They told us about how subtle language and communication difficulties affected their ability to learn, take part in certain activities and seek help. They talked about how subtle difficulties affect their ability to talk to new people, talk in groups and ultimately make friends. They also told us about the emotional upset that these subtle difficulties could have. They suggest that communication breakdown leads to negative feelings, but also that negative feelings can lead to more difficulties explaining themselves. The results of this study suggest that we should do more research on the effects of subtle language and communication difficulties. There are also implications for clinical practice. We should identify subtle language and communication difficulties through thorough assessment because these are often missed. We should also develop therapy and strategies that are aimed at individuals with subtle language and communication difficulties because this could help prevent additional difficulties with learning, help-seeking, friendship-making and emotional well-being.

Classroom Teachers' Implementation of the Social Stations Intervention to Improve the Verbal Initiations and Responses of Students with Autism

Students with autism often show challenges in social communication, particularly in initiating and responding behaviors. While the classroom offers a natural context for peer interactions, few interventions are designed specifically for classroom settings. This study investigated the effects of a classroom-teacher implemented social communication intervention, known as Social Stations, on the initiating and responding behaviors of students with autism. The study was set in an inclusive primary school, with the teacher embedding the intervention into the student's daily literacy lessons. All students with autism showed significant improvements in the targeted behaviors, with improvements maintained over time. This study suggests that social communication interventions can be implemented by teachers as part of a daily classroom program.

Conversation Skills in Chinese-Speaking Preschoolers with Autism: The Contributing Role of Parents' Verbal Responsiveness

Children with autism spectrum disorder (ASD) have conversation deficits, yet the growth of conversation abilities is understudied, especially in Chinese-speaking populations. Little is known about whether their parents' verbal responsiveness and redirectives are related to their conversation skills. Children with ASD (N = 37; M = 5;5) and their parents contributed their language samples. These children interacted with their parents at four time points over nine months. The number of conversational turns and the proportion of child-initiated conversation (but not the proportion of children's appropriate responses) grew over nine months. After controlling for time, autism severity, and language skills, parents' verbal responsiveness positively predicted children's appropriate responses. Parents' redirectives negatively predicted the proportion of children's appropriate responses and the number of conversational turns.

Autistic Adults May Be Erroneously Perceived as Deceptive and Lacking Credibility

We hypothesized that autistic adults may be erroneously judged as deceptive or lacking credibility due to demonstrating unexpected and atypical behaviors. Thirty autistic and 29 neurotypical individuals participated in video-recorded interviews, and we measured their demonstration of gaze aversion, repetitive body movements, literal interpretation of figurative language, poor reciprocity, and flat affect. Participants (N = 1410) viewed one of these videos and rated their perception of the individual's truthfulness or credibility. The hypothesis was partially supported, with autistic individuals perceived as more deceptive and less credible than neurotypical individuals when telling the truth. However, this relationship was not influenced by the presence of any of the target behaviors, but instead, by the individual's overall presentation.

Pragmatic Language and Social Communication Tests for Students Aged 8–18 Years: A Review of Test Accuracy

Purpose

The accuracy of commercially available pragmatic language and social communication tests was reviewed.

Method

Online sources were searched to identify tests providing stand-alone pragmatic or social communication scores. Test manuals were examined to extract information about clinical and typically developing group comparisons, including sample size, inclusionary/exclusionary criteria, and mean group differences. Classification accuracy metrics, including sensitivity, specificity, optimal cut scores, and likelihood ratios, were reviewed.

Results

Six domain-specific pragmatic language and social communication tests and four omnibus language tests were identified. Test content varied and included video and audio recordings and question-and-answer formats to address hypothetical social vignettes, retell and comprehend narratives, interpret nonliteral language and multiple-meaning words, identify and display emotions, and infer another's perspective. Sample size and inclusionary/exclusionary criteria for comparisons of students with typical development (TD), developmental language disorder (DLD), autism spectrum disorder (ASD), and social (pragmatic) communication disorder (SPCD) varied widely. Mean group differences between TD and ASD or SPCD groups were generally larger (i.e., > 0.5 SD to > 2.0 SD s) than TD and DLD comparisons. Test authors interpreted these results as support for the accuracy of tests to identify deficits associated with ASD and SPCD and not DLD. Classification accuracy was reported for five domain-specific tests. Optimal cut scores ranged from 85 to 92, with adequate sensitivity and specificity (i.e., ≥ 80%); however, positive likelihood ratios and associated confidence intervals revealed limited confidence in reported levels.

Conclusions

Inadequate sample description for comparison and classification studies limit a clinician's ability to compare a student's profile with those in the samples. Although none of the tests meet all standards for test accuracy reviewed in this report, a checklist to guide test selection is provided to assist in identifying the best available test for a student's profile, if a test is needed.

A meta-analysis of prosody in autism, Williams syndrome, and Down syndrome

Prosody, the rhythm and melody of speech, is an important component of effective communication, and it is an area of difficulty for many populations who struggle with communication. This paper is a meta-analysis of nine studies (and two sets of unpublished data) that assessed prosody using the Profiling Elements of Prosody in Speech-Communication (PEPS-C; Peppé & McCann, 2003) in autism spectrum disorder, Williams syndrome, and Down syndrome. Our original goal was to include studies involving any neurodevelopmental disorder that is commonly associated with intellectual disability, yet our systematic search, which included three databases (i.e., PsychInfo, ERIC, and PubMed), only identified studies involving these three groups. To be included in the meta-analysis, studies had to include a group (n ≥ 3 participants) with a neurodevelopmental disorder commonly associated with intellectual disability and a typically developing comparison group matched on chronological age, nonverbal abilities, or verbal abilities. Studies also needed to report original data using the PEPS-C and be available in English. Study quality was assessed using a checklist adapted from Downes et al. (2016). Results revealed that prosodic form was a weakness for each etiology, while unique patterns of strengths and weaknesses were evident for prosodic functions. Groups with autism (n = 5), all classified as high-functioning or with Asperger's syndrome, exhibited weakness in emotional affect but some relative strengths with turn-end and focus tasks. Groups with Williams syndrome (n = 4) demonstrated weaknesses on phrase/sentence-level tasks and relative strengths on word-level tasks. Groups with Down syndrome (n = 2) had the greatest difficulty overall, though performance was better on receptive (vs. expressive) function tasks. By combining studies and related subtasks of the PEPS-C, we are able to more confidently generalize findings for each population and identify targets for intervention. However, given the limited number of studies identified, this paper also highlights the need for more research on prosody in intellectual disability.

Spontaneous Expressive Language Profiles in a Clinically Ascertained Sample of Children With Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) have varying degrees of language impairment across multiple domains, which may include deficits in syntactic, pragmatic, and/or semantic skills. The heterogeneity of language profiles within ASD, coupled with the limited scope of existing standardized language measures, makes a comprehensive assessment of language impairments in ASD challenging. The Observation of Spontaneous Expressive Language (OSEL) is a new measure developed to capture children's spontaneous use of language in a naturalistic setting. The current study used the OSEL to examine the patterns of spontaneous expressive language abilities of 87 clinically ascertained children with ASD from 2 to 12 years. As expected, children with ASD were significantly more impaired in their spontaneous use of language compared to typically developing peers. Syntax and narrative skills continued to increase with age from toddler to elementary school years in cross-sectional comparisons. Pragmatic skills improved form toddler to preschool years but remained stable from preschool to elementary school years. Preliminary data also demonstrated significant improvements in OSEL syntax scores over time for a subset of children followed longitudinally (n = 8). Children with ASD consistently showed more impairments in spontaneous expressive language captured on the OSEL compared to language skills measured by other more structured standardized assessments, despite moderate convergent validity among those measures. Results suggest that impairments in the spontaneous and functional use of expressive language persist into middle childhood for many children with ASD, and a comprehensive assessment approach can lead to more precisely targeted treatment addressing specific language profiles. LAY SUMMARY: This study aimed to examine the variable language profiles in children with ASD. Children with ASD were shown to have impairments in the structure, meaning, and social use of language. These challenges were captured best by a measure that was created to assess the spontaneous use of language in a naturalistic environment. The results of this study emphasize the importance of a comprehensive assessment of language in ASD to inform treatment.

Social Communication and Structural Language of Girls With High-Functioning Autism Spectrum Disorder

Purpose The purpose of this study was to characterize social communication and structural language of school-age girls with high-functioning autism spectrum disorder (HF-ASD) compared to a matched group of girls who are typically developing (TD). Method Participants were 37 girls between 7;5 and 15;2 (years;months)-18 HF-ASD and 19 TD. Children completed the Test of Pragmatic Language-Second Edition (TOPL-2) and Clinical Evaluation of Language Fundamentals-Fifth Edition. Parents completed the Children's Communication Checklist-2 United States Edition (CCC-2) and Receptive and Expressive Communication subdomains of the Vineland Adaptive Behavior Scales-Second Edition. Results In the area of social communication, girls with HF-ASD earned significantly lower scores and were more often classified as having an impairment on the TOPL-2 and the CCC-2. However, 28% and 33% earned average scores on the TOPL-2 and the CCC-2, respectively. In the area of structural language, no significant differences were found between groups on Clinical Evaluation of Language Fundamentals-Fifth Edition indexes. In contrast, girls with HF-ASD earned significantly lower scores and were more often classified as having an impairment on the Vineland Adaptive Behavior Scales-Second Edition. Sixty-one percent and 83% scored below average on the Receptive and Expressive Communication subdomains, respectively. Conclusions It has been argued that girls with HF-ASD, when compared to boys with HF-ASD, may have advantages for social communication and structural language that mask their impairments. However, when compared to girls who are TD, girls with HF-ASD demonstrated impaired social communication and structural language. Clinicians should include and carefully examine multiple sources of information when assessing girls with HF-ASD.

Comparing the Pragmatic Speech Profiles of Minimally Verbal and Verbally Fluent Individuals with Autism Spectrum Disorder

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.

Partner Perceptions of Conversations with Individuals with Autism Spectrum Disorder

Pragmatic difficulties resulting in problems with reciprocal conversation are widely studied in individuals with autism spectrum disorder (ASD). There is some consensus on the conversation differences between individuals with autism compared to neurotypical groups and groups with other developmental delays. There is little information on whether conversation partners (neurotypical or with ASD) of individuals with ASD find these differences problematic. The results indicate that behaviors reported to be the most problematic were not necessarily behaviors commonly addressed in research. Further, some conversational capacities that have received less research focus were perceived as more problematic. Although conversation partners who had ASD themselves reported the frequency of behaviors similarly to the neurotypical group, they did not find the behaviors as problematic.

Outcomes of a practical approach for improving conversation skills in adults with autism

Many individuals with autism spectrum disorder (ASD) have deficits in conversation skills that can interfere with the development of personal and professional relationships. Further research is needed on efficient interventions for targeting conversation skills in adults with ASD and for evaluating the social validity of the outcomes. In this study, 2 practitioners implemented a 4-week training program for 5 adults with ASD that combined individualized computer-based instruction (CBI) and practice with peers to promote the acquisition, maintenance, and generalization of conversation skills. Training was associated with improvements in 12 of 13 skills across participants. These findings, along with peer ratings of the participants' conversation skills, suggest that this model is a promising, socially valid approach for improving conversation skills in adults with ASD.

Pragmatic and Conversational Features of Arabic-Speaking Adolescents With Autism Spectrum Disorder: Examining Performance and Caregivers' Perceptions

Purpose This study investigates the features of pragmatic and conversational skills in the language of Arabic-speaking adolescents with autism spectrum disorder (ASD) by comparing them with typically developing (TD) Arabic-speaking adolescents in Saudi Arabia. It aims to identify the differences in the pragmatic skills of the two groups and the perception of those skills by caregivers, with respect to four main pragmatic areas: discourse management, communicative function, conversational repair, and presupposition abilities. Method Data for this study were collected from 15 Saudi adolescents with ASD and a control group of 15 TD adolescents, matched for gender and language abilities. All the participants were in the normal IQ range. The caregivers of the adolescents with ASD and TD adolescents also participated in this study. Data were collected on the adolescents' performances using the Yale in vivo Pragmatic Protocol. In addition, the Pragmatics Profile of Everyday Communication Skills (PPECS) was used to collect data on the caregivers' perceptions of the adolescents' abilities. The combination of tools in this study allows for a unique comparison between actual performance and caregivers' perceptions. Results As expected, both the adolescents' performances and the caregivers' perceptions reflected an overall deficit in the pragmatic and conversational skills of adolescents with ASD. However, we also identified an inconsistency between the caregivers' estimation of the participant's pragmatic abilities and the actual abilities demonstrated by the adolescents. In particular, TD adolescents performed significantly better than adolescents with ASD in the pragmatic areas of turn-taking, topic maintenance, and topic initiation, but the caregivers did not detect differences between the two groups in these discourse management abilities. Conclusions This study has important implications for both ASD interventions and assessment. It provides a comprehensive assessment approach for measuring pragmatic skills, including both direct (participants' performances) and indirect (caregivers' perceptions) measures. Future research may benefit from adopting the combined approach used in this study to explore pragmatics in ASD. Differences between caregivers' perceptions and the performances of individuals with ASD should be considered, as well as the influence of various factors on their communication.

Developing Social Communication Skills Using Dual First-Person Video Recording Glasses: A Novel Intervention for Adolescents with Autism

Adolescents with autism often experience pronounced difficulties with social communication, and novel interventions designed to improve core abilities are greatly needed. This study examines if providing immediate video feedback, an extension of video self-modeling, can aid adolescents with autism to self-identify strengths and irregularities from their social interactions. Using multiple baseline design across four participants, individuals engaged in naturalistic conversations wearing video recording glasses. During the intervention, videos were reviewed immediately and participants recognized when they were not following typical social-communicative convention. Based on observational data coded from videos, all four participants modified their behavior during subsequent conversations. Although adolescents with autism may hypothetically know to behave, viewing themselves on video may provide practical cues to support social insight and behavioral change.

A Preliminary Study of Writing Skills in Adolescents with Autism Across Persuasive, Expository, and Narrative Genres

Writing is often difficult for individuals with autism spectrum disorder (ASD), yet relatively little literature exists that profiles specific strengths and needs within this area. This preliminary investigation compares the written language skills of adolescents with ASD without intellectual disability (n = 14) to typically developing (TD) adolescents (n = 12). Writing samples from persuasive, expository, and narrative genres were elicited. Variables of sample length, writing productivity, syntax, lexical diversity, and macrostructure were analyzed. In the persuasive and expository genres, the ASD group scored significantly lower than the TD group on sample length and some aspects of macrostructure. The ASD group scored higher than the TD group on lexical diversity in the persuasive genre. Other comparisons yielded large effect sizes but were not statistically significant.

Using community-engaged methods to adapt virtual reality job-interview training for transition-age youth on the autism spectrum

BACKGROUND

Virtual Reality Job-Interview Training (VR-JIT) is an efficacious Internet-based intervention for adults with severe mental illness (SMI). Evaluations of VR-JIT have shown improved interview skill and access to employment in several cohorts of adults with SMI and with autism spectrum disorders (ASD). VR-JIT trains participants how to fill out job applications and handle job interviews through e-learning content and applied practice. Trainees receive feedback through in-the-moment nonverbal cues, critiques, and recommendations for improving performance. Our study sought to adapt VR-JIT for transition-age youth with ASD (TAY-ASD).

METHODS

We recruited TAY-ASD and adult stakeholders from public and charter schools, transition programs, and community service providers. Participants provided feedback on VR-JIT to enhance its applicability to TAY-ASD. We used community-engaged methods to process and analyze data from TAY-ASD and stakeholders, presented their quantitative and qualitative responses to community and scientific advisory boards for review and recommendations, and adapted the intervention design and content.

RESULTS

Our adaptations included adding diversity (gender; race/ethnicity) to the virtual hiring manager; shortening the interview by reducing response options; increasing social storytelling to enhance engagement with VR-JIT core components; adding employment opportunities more relevant to younger workers; reducing the reading level; and making the e-learning content more accessible by adding bullet points, voiceover, and imagery/video; and adding new learning goals.

CONCLUSIONS

This study presents a rigorous and innovative community-engaged methodology for adapting VR-JIT to meet the needs of TAY-ASD. We review our engagement with TAY-ASD and stakeholders, and discuss the standardized coding scheme we used to adapt VR-JIT and the usefulness and limitations of employing this methodology in adapting other behavioral interventions.

Relations between Everyday Executive Functioning and Language in Youth with Down Syndrome and Youth with Autism Spectrum Disorder

Language and executive functioning are major impairments in many neurodevelopmental disorders, but little is known about the relations between these constructs, particularly using parent-report. Thus, the current research sought to examine relations between executive function and language in two groups - Down syndrome (DS; n=41; Mage = 11.2) and autism spectrum disorder (ASD; n=91; Mage = 7.7). Results were as follows: in DS, executive function predicted pragmatic, but not structural language after covarying for age, sex, and social functioning; in ASD, executive function predicted both. Findings highlight the interrelatedness of language and executive functioning and may have implications for intervention development.

Peer's pragmatic language outcomes following a peer-mediated intervention for children with autism: A randomised controlled trial

BACKGROUND

Peer-mediated pragmatic language interventions can be of benefit to children with autism as they simultaneously target an individual child's pragmatic language skills and contextual factors related to social interactions. However, little is known about peer outcomes following peer-mediated interventions.

AIMS

This study evaluated the pragmatic language outcomes for typically-developing (TD) playmates who participated in a peer-mediated intervention for children with autism.

METHODS

Dyads (child with autism and TD-playmate; n = 71) were randomised to a treatment-first or waitlisted-first comparison group. Dyads attended 10 clinic play-sessions with a therapist and parents mediated home-practice. The Pragmatics Observational Measure 2nd edition (POM-2), and Social Emotional Evaluation (SEE) evaluated pragmatics before, after and 3-months following the intervention.

RESULTS

Changes in both outcomes measures were equivalent for intervention-first and waitlisted TD-playmates, but all TD-playmates made significant gains in pragmatics following the intervention. Treatment effects maintained for 3-months (p < 0.001-0.014, d = 0.22-0.63), were equivalent in different environments (clinic and home). Peer relationship type and therapist profession mediated POM-2 scores across the study, while expressive language ability moderated SEE scores.

CONCLUSIONS

This peer-mediated intervention had a positive impact on TD-playmate's pragmatic language capacity and performance.

A Systematic Review of Linguistic and Verbal Behavior Outcomes of Pivotal Response Treatment

Pivotal Response Treatment (PRT) is a popular intervention for improving targeted and untargeted communication skills for learners with autism. We systematically reviewed communication outcomes reported in experimental research to determine linguistic forms and verbal behavior functions associated with PRT. We found most researchers aggregated results or did not report sufficient detail to determine linguistic forms and/or verbal behavior functions. Generalization of communication skills to untargeted people, settings, materials, and/or activities was evident. However, only one study clearly indicated untargeted linguistic forms emerged following PRT, and no researchers described results that indicated improved generalized and collateral verbal behavior functions. We suggest PRT researchers more clearly define and report primary, generalized, and collateral communication-specific outcomes in order to advance research and practice.
