RESUMO

Purpose Children with autism spectrum disorder (ASD) are at increased risk of experiencing difficulties with the development of literacy, including the emergent literacy skills recognized to underpin conventional literacy success. Comprehensive assessment is essential. Characteristics of ASD can make assessment challenging, and this can be compounded when children are unable to demonstrate their skills using spoken language. The purpose of this clinical tutorial is to outline the process of emergent literacy assessment for children with ASD who have limited verbal communication skills. A case example of a 5-year-old boy is presented. Method Pertinent literature is reviewed around the literacy profiles of children with ASD, the subgroup of children with ASD who have limited verbal communication skills, key components of emergent literacy, and previous research examining the emergent literacy abilities of children with ASD. The case report is described in depth and emphasizes the key factors to consider when designing an assessment battery and protocol. Results The case example information is interpreted, and its application is discussed. Key outcomes are highlighted including a greater understanding of the child's literacy strengths and needs and the implications for individualized instruction. Conclusion The clinical tutorial highlights the need for a comprehensive, well-planned assessment approach that involves all members of the educational team, and that is considerate to the needs of the individual child and responsive to their communication needs.

RESUMO

Practitioners need validated strategies for teaching children with significant multiple disabilities (e.g., cognitive, motor, and sensory disability) to use tangible symbols for expressive communication. This single-case experimental design study replicated the positive effect of an adapted protocol for teaching Phase 1 of the Picture Exchange Communication System (PECS) using tangible symbols and extended it to a younger group (4-7 years old) of learners with multiple disabilities. It also tested the effect of an adapted protocol for Phase 2 of PECS to incorporate use of a single switch speech-generating device to gain the attention of an adult communication partner. Two of three students who reached mastery in Phase 1 also reached mastery in Phase 2 and may have generalized requesting behavior from the interventionist (i.e., researchers) to their classroom teacher. Results add to the growing evidence base that shows that the adapted PECS Phase 1 procedures are a promising practice for learners with multiple disabilities, including sensory impairment, and provide preliminary evidence for a more efficient and effective approach to adapting PECS Phase 2 than previously studied for this group of learners. Directions for future research and recommendations for practice are provided.

RESUMO

This was a two-phase study that aimed to (a) develop a tool for assessing visual attention in individuals with Rett syndrome using AAC with a communication partner during naturalistic interactions in clinical settings; and (b) explore aspects of the tool's reliability, validity, and utility. The Assessment of Visual Attention in Interaction (AVAI) tool was developed to assess visual attention operationalized as focused gazes (1 s or longer) at the communication partner, an object, and a symbol set. For the study, six video-recorded interactions with nine female participants diagnosed with Rett syndrome (range: 15-52-years-old) were used to calculate intra- and inter-rater agreement, and 18 recorded interactions were analyzed to examine sensitivity to change and acceptability. There was a significant difference in the AVAI results between two conditions (with and without aided-language modeling). Inter-rater agreement ranged from moderate and strong. There was a range in scores, indicating that the AVAI could differentiate between participants. The AVAI was found to be reliable, able to detect change, and acceptable to the participants. This tool could potentially be used for evaluating interventions that utilize aided AAC.

RESUMO

INTRODUCTION: Language dysfunction has recently been suggested to be one route to alexithymia, an impairment in recognizing and communicating one's own emotions. Neuropsychological evidence is needed to investigate the possibility that acquired language problems could underlie acquired alexithymia. METHOD: This project examined data from a large group of chronic stroke patients (N = 118) to test whether self-reported or behavioral measures of language and communication problems were associated with alexithymia. We also examined the impact of hemisphere of damage on alexithymia. RESULTS: We found no differences in alexithymia levels for patients with observed language impairments on brief tests of picture naming, comprehension, and reading vs unimpaired patients. However, self-reported communication difficulties were found to be associated with higher scores of alexithymia, even after controlling for depression and anxiety. Patients with left- versus right-hemisphere damage did not differ in their alexithymia scores. CONCLUSIONS: We found partial support for the language hypothesis of alexithymia. We discuss potential reasons for the discrepant findings between the self-report and objective language measures and suggest that self-report measures may be more sensitive to milder, more pragmatic language impairments, as opposed to the severe structural language impairments measured by the cognitive screening tests.

RESUMO

More people with autism spectrum disorder (ASD) are now being identified in the criminal justice system, and in parallel with this increase, the prevalence of ASD in the community has risen more than 150 % in the same time period. In this article, I will argue that this increase is due to a reclassification of those individuals whose social, communicative and behavioural function is at the lower end of the normal range. Put simply, extremes of these quantitative traits are now being conceptualised as 'disorder'. This has particular relevance for the criminal justice system as such traits are over-represented in this population: as such, it is likely that increasing numbers of people who are incarcerated will receive an ASD diagnosis. This will have major implications for where best, and how best, to manage such individuals using a framework of 'disorder' versus 'difference'.

RESUMO

BACKGROUND: Adolescents with attention-deficit hyperactivity disorder (ADHD) may have impaired social cognition and communication. However, the functioning of the brain networks involved in the social cognition and communication impairment in ADHD patients remains unclear. METHODS: In total, 18 adolescents with ADHD and 16 age- and sex-matched typically developing adolescents (controls)-all of whom underwent a brain magnetic resonance imaging examination-were enrolled. Their parents filled out Swanson, Nolan, and Pelham IV (SNAP-IV) and Social Responsiveness Scale (SRS) questionnaires. Functional connectivity analyses based on the default mode network, frontoparietal network, and cinguloopercular network were performed. RESULTS: Compared with controls, adolescents with ADHD exhibited higher total and subscale scores on SNAP-IV and SRS. Higher SNAP-IV and SRS scores were associated with higher functional connectivity between the default mode network (ventromedial prefrontal cortex) and cinguloopercular network (anterior insula) and between the FPN (dorsolateral and prefrontal cortex) and cinguloopercular network, but with lower functional connectivity between the default mode network (posterior cingulate cortex) and frontoparietal network (inferior parietal lobule) and between the default mode network (precuneus) and cinguloopercular network (temporoparietal junction). DISCUSSION: Social cognition and communication impairment and ADHD may commonly share the aberrant functional connectivity in the default mode network, frontoparietal network, and cinguloopercular network.

RESUMO

Introduction: The patients' perception of how communication dysfunction may cause a disadvantage is important information for the clinical decision-making process.Objectives: This study aimed to translate the self-evaluation of communication experiences after laryngectomy (SECEL) to the European Portuguese (EP) and to assess its feasibility, acceptability, reliability, and validity.Material and methods: A cross-sectional study was carried out, and a cluster sample of seven ENT outpatient clinics was drawn. The EP-SECEL was filled in by 129 people with laryngectomy, aged 29-81 years and 25 of those completed it in the second time. Patients have also filled in the European Organization for Research Treatment of Cancer Quality of Life Questionnaire (EORCT), the core quality of life questionnaire (QLQ-C30) and the 35-item Head and Neck module (H&N35).Results: The EP-SECEL has the same conceptual meaning, semantics, idiomatic, format and score equivalence as the original one. Psychometric analyses revealed that it is feasible (missing <1%, to fill out took about 15 minutes for most patients), acceptable (floor and ceiling effects inferior to 15%), reliable (excellent internal consistency, Cronbach's alpha = 0.90, and moderate test-retest, Spearman's rhô = 0.64), well-constructed (66% of the total variance is explained by exploratory factor analysis), significantly convergent (correlates with the EORTC QLQ-C30 and H&N35) and validly discriminates people with total and partial laryngectomy as well as people with different primary means-of-communication.Conclusions: This study supports that the EP-SECEL has sufficient psychometric qualities to be considered an adequate tool to be recommended for assessing health-related quality of life among laryngectomy patients.

RESUMO

Tic disorders are characterized by a class of responses assumed to be neurobiological in origin. Still, several studies have shown that tic frequency can be influenced by antecedent environmental events and social consequences. Prior reviews have summarized the effects of environmental events but have not examined relations between tic diagnosis, behavioral deficits (e.g., intellectual disability), tic topography, and the consequences observed to maintain tics. These variables might be important when attempting to predict or identify relevant consequences. A more thorough understanding of the variables that maintain and give rise to tics might also be useful in predicting responsiveness to treatment and intervention refinement. We reviewed and summarized results from the 13 attempts to experimentally identify maintaining consequences for tics (i.e., functional analyses) that have been published to date. We examined patterns of functions across tic diagnoses (i.e., Tourette's syndrome or not), communication impairments (i.e., an intellectual disability or reported language difficulty), and tic topography. Results suggested that individuals with Tourette's syndrome and those without communication impairments are more likely to have functional analysis outcomes consistent with automatic reinforcement, but exceptions in both directions highlight the utility of functional analysis in treating tics.

RESUMO

BACKGROUND: Children with a significant cognitive and motor developmental delay are pre-symbolic communicators. The primary aim of this study was to reveal the variability within the communicative functioning of this group of children in terms of communication level, the reasons to communicate and behavioural expressions. METHODS: Twenty-six children between 14 and 58 months with a significant cognitive and motor developmental delay were recruited. The Communication Matrix of Rowland (2011, Communication Disorders Quarterly, 32, 190) was used to integrate different sources of information on the children's communicative functioning. RESULTS: These children primarily communicated at the level of pre-intentional and intentional behaviour, aimed at refusing, obtaining and, to a lesser extent, social purposes. CONCLUSIONS: To develop or adapt early intervention strategies, and to monitor progress in communicative development, an even more nuanced view on these children's communicative utterances in terms of frequency, duration, idiosyncrasy and context relatedness is needed.

RESUMO

BACKGROUND: People with an intellectual disability (ID) are vulnerable to communication impairments, with consequences for employment, education, and social participation. AIMS: To identify the communication skills of a population of adults (40+ years) with ID and explore relationships between individual and environmental factors and communication skills. METHODS AND PROCEDURES: Data from a sample of 601 adults with ID was selected from the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing (IDS-TILDA) addressing communication characteristics, demographics, co-morbidities, challenging behaviours, and social participation. A multiple regression model and a decision-making tree were built to identify factors related to communication abilities. OUTCOMES AND RESULTS: Overall, 57.9 % of participants experienced communication difficulties, with 23.5 % reporting severe difficulties. Only 75.1 % of participants communicated verbally; more than half found communicating with professionals and non-familiar partners difficult. Level of ID, low social participation, challenging behaviours, and diagnosis of Down syndrome were significantly associated with communication difficulties. CONCLUSIONS AND IMPLICATIONS: Communication difficulties are prevalent in adults with ID and are influenced by complex factors. Interventions to enhance interaction and quality of life of individuals with ID should consider communication opportunities, needs, and barriers.

RESUMO

Despite the importance of expressive language for individuals with autism spectrum disorder (ASD), expressive language assessments are not consistently included in ASD research and many studies do not adequately describe participants' verbal abilities. A valid and efficient measure of expressive language would facilitate consistent reporting across ASD research studies and provide data for additional analyses. The current study developed a new Autism Diagnostic Observation Schedule (ADOS-2) expressive language score and examined convergent and divergent validity in a large, well-defined sample of children with ASD. This score was highly correlated with other measures of expressive language (including parent-report, direct assessment, and clinician ratings) and less strongly correlated with measures of receptive language and nonverbal cognitive ability, providing good evidence of convergent and divergent validity.

RESUMO

This study assessed white matter microstructural integrity and behavioral correlates for children with severe congenital hypothyroidism (CH) who were identified and treated early following newborn screening. Eighteen children with severe CH and 21 healthy controls underwent a battery of behavioral measures of hearing, language and communication, along with diffusion MR imaging. Tract-based spatial statistics were performed on standard diffusion parameters of fractional anisotropy and diffusivity metrics. Microscopic diffusion anisotropy mapping based on the Spherical Mean Technique was also used to evaluate biologically specific metrics. Compared with age-matched controls, children with severe CH had poorer hearing and communication skills, albeit generally within normal limits. Children with severe CH had fractional anisotropy that was significantly lower in the cerebellum, bilateral thalami and right temporal lobe, and radial diffusivity that was significantly higher in the cerebellum and bilateral thalami. Microscopic fractional anisotropy and intra-neurite volume fraction were also significantly decreased, and transverse microscopic diffusivity was significantly increased, in the CH group in areas including the cerebellum, thalamus, occipital lobe, and corpus callosum, and in the white matter adjacent to sensorimotor cortex, particularly in the left hemisphere. Significant and widespread correlations were observed between behavioral measures and measures of white matter microstructural integrity in children with CH. The results indicate that children with severe CH who are identified through newborn screening may have significant brain white matter microstructural abnormalities despite early treatment.

RESUMO

Many individuals with traumatic brain injury (TBI) rely on augmentative and alternative communication (AAC) supports to meet functional communication needs. The use of images to display message content may be advantageous for this population, given deficits in literacy, visual processing, and cognition. Grid and visual scene displays are two options for presenting images within AAC systems. Eye-tracking technology was utilized to evaluate the visual processing patterns of 13 adults with a history of TBI and 13 adults without TBI when interpreting themes depicted in grid and visual scene displays. Results indicated that differential processing and effort was required when interpreting the two display types. Both groups of participants required significantly more visual fixation time and exhibited patterns consistent with greater cognitive effort when identifying themes depicted in grids compared to visual scenes (i.e., greater numbers of short fixations). The participants with TBI were overall less efficient than those without TBI when identifying themes presented in both AAC display types. These results add to the growing body of evidence indicating that visual scenes may more effectively represent complex concepts than decontextualized, grid-based images for individuals with TBI. Additional clinical implications are discussed.

RESUMO

Abnormal auditory discrimination neural processes, indexed by mismatch fields (MMFs) recorded by magnetoencephalography (MEG), have been reported in verbal children with ASD. Association with clinical measures indicates that delayed MMF components are associated with poorer language and communication performance. At present, little is known about neural correlates of language and communication skills in extremely language impaired (minimally-verbal/non-verbal) children who have ASD: ASD-MVNV. It is hypothesized that MMF delays observed in language-impaired but nonetheless verbal children with ASD will be exacerbated in ASD-MVNV. The present study investigated this hypothesis, examining MMF responses bilaterally during an auditory oddball paradigm with vowel stimuli in ASD-MVNV, in a verbal ASD cohort without cognitive impairment and in typically developing (TD) children. The verbal ASD cohort without cognitive impairment was split into those demonstrating considerable language impairment (CELF core language index <85; "ASD-LI") versus those with less or no language impairment (CELF CLI >85; "ASD-V"). Eighty-four participants (8-12 years) were included in final analysis: ASD-MVNV: n = 9, 9.67 ± 1.41 years, ASD: n = 48, (ASD-V: n = 27, 10.55 ± 1.21 years, ASD-LI: n = 21, 10.67 ± 1.20 years) and TD: n = 27, 10.14 ± 1.38 years. Delayed MMF latencies were found bilaterally in ASD-MVNV compared to verbal ASD (both ASD-V and ASD-LI) and TD children. Delayed MMF responses were associated with diminished language and communication skills. Furthermore, whereas the TD children showed leftward lateralization of MMF amplitude, ASD-MVNV and verbal ASD (ASD-V and ASD-LI) showed abnormal rightward lateralization. Findings suggest delayed auditory discrimination processes and abnormal rightward laterality as objective markers of language/communication skills in both verbal and MVNV children who have ASD. Autism Res 2019, 12: 1225-1235. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Brain imaging showed abnormal auditory discrimination processes in minimally-verbal/non-verbal children (MVNV) who have autism spectrum disorder (ASD). Delays in auditory discrimination were associated with impaired language and communication skills. Findings suggest these auditory neural measures may be objective markers of language and communication skills in both verbal and, previously-understudied, MVNV children who have ASD.

RESUMO

Rett syndrome (RTT) is an X-linked genetic disorder that occurs predominantly in females. The clinical picture associated with RTT is defined by core and supportive consensus criteria, with a period of behavioural regression being a conditio sine qua non. This review sheds light on atypical neurofunctions and potential behavioural biomarkers before the onset of regression. The main focus lies on (a) motor development, especially on purposeful hand movements and the occurrence of stereotypies; and (b) speech-language and socio-communicative development. We outline potentially specific atypical behavioural patterns in these domains (e.g., vocalisations on inspiratory airstream) and different developmental traits of regression: (i) non-achievement of certain milestones: 'regression', here, might point to the fact that the lack of respective behavioural patterns appeared more and more worrisome with increasing age; and (ii) developmental milestones were achieved and functions deteriorate or even get lost during regression. To conclude, we are not quite there yet, but seem to be on the right track towards defining new and reliable neurofunctional markers for early detection of RTT.

RESUMO

There is substantial evidence of word retrieval impairment as indicated by poor performance on the category fluency test in autism spectrum disorder (ASD). However, little is known about the neural mechanisms underlying this impairment. Functional neuroimaging studies have shown that the lateral frontal cortex plays a key role in flexible word retrieval. Thus, we examined whether individuals with ASD exhibited altered frontal processing during the category fluency test using functional near-infrared spectroscopy (fNIRS). Twenty-two adolescents with high-functioning ASD (20 males) and 22 typically developing (TD) adolescents (16 males) aged 11-18 years were recruited. All underwent a category fluency paradigm, which required production of animal or means of transportation words for 1 min each although their frontal hemodynamic changes were recorded with fNIRS. We found that adolescents with ASD produced fewer animal but not transportation words (group-by-category interaction: P = 0.003), suggesting differential word retrieval impairment. In addition, unlike TD adolescents who exhibited activation primarily in lateral frontal regions during word production, adolescents with ASD had comparable activation across lateral and medial frontal regions. More importantly, this lack of lateral-medial distinction of activation, which was associated with poor word retrieval, differed significantly between groups only in the animal category (group-by-category interaction: P = 0.018). Thus, our findings implicate frontal lobe dysfunction in the impairment of differential word retrieval in adolescents with ASD. The relatively greater involvement of the medial frontopolar cortex might reflect the use of nonspecialized brain regions to compensate for the category-dependent difficulties with word retrieval in ASD. Autism Res 2019, 12: 600-613. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Using an optical imaging tool, we found that adolescents with autism had difficulties with producing semantically related words and exhibited frontal lobe dysfunction. Nonetheless, poor word production and altered brain processing was only seen when these adolescents were asked to produce words from a category of living things but not nonliving things (i.e., animals but not means of transportation). Category-dependent word retrieval problems and frontal lobe dysfunction might be two features of this disorder.

RESUMO

Objective: To involve people living with amyotrophic lateral sclerosis (plwALS) in the scoping and identification of research priorities related to the changes in ALS communication including the use of augmentative and alternative communication (AAC). Methods: Two focus groups of plwALS at early and late stages of change to speech intelligibility were carried out as a patient and participant involvement exercise. The transcriptions of these groups were analyzed thematically and compared between groups. Results: Aspects of anticipation, preparation, adaptation and partnership were identified as key to dealing with communication change as a result of ALS. In particular the involvement of partners was clearly significant, as was the impact on them as well as the plwALS. PlwALS successfully contributed to focus groups and the process of group discussion about communication itself appeared constructive. Conclusions: Research and new interventions should focus further on how to support the partners of plwALS. Future research with plwALS should place AAC strategies and technology in the context of wider communication and investigate how best to support the anticipation, preparation and adaptation to communication change. Specific areas of research need relating to this support are suggested. IMPLICATIONS FOR REHABILITATION People living with ALS (plwALS) are rarely involved in setting the research agenda in the areas of speech and augmentative and alternative communication (AAC). Enabling plwALS to contribute to research, even those with no speech, is feasible with appropriate support. Feedback indicates that communication change and AAC are experienced in different ways by plwALS. Research and intervention should focus on how to support the anticipation, preparation and adaptation to communication change for plwALS.

RESUMO

Purpose Research manipulating the complexity of housing environments for healthy and brain-damaged animals has offered strong, well-replicated evidence for the positive impacts in animal models of enriched environments on neuroplasticity and behavioral outcomes across the lifespan. This article reviews foundational work on environmental enrichment from the animal literature and considers how it relates to a line of research examining rich communicative environments among adults with aphasia, amnesia, and related cognitive-communication disorders. Method Drawing on the authors' own research and the broader literature, this article first presents a critical review of environmental complexity from the animal literature. Building on that animal research, the second section begins by defining rich communicative environments for humans (highlighting the combined effects of complexity, voluntariness, and experiential quality). It then introduces key frameworks for analyzing and designing rich communicative environments: distributed communication and functional systems along with sociocultural theories of learning and development in humans that support them. The final section provides an overview of Hengst's and Duff's basic and translational research, which has been designed to exploit the insights of sociocultural theories and research on environmental complexity. In particular, this research has aimed to enrich communicative interactions in clinical settings, to trace specific communicative resources that characterize such interactions, and to marshal rich communicative environments for therapeutic goals for individuals with aphasia and amnesia. Conclusions This article concludes by arguing that enriching and optimizing environments and experiences offers a very promising approach to rehabilitation efforts designed to enhance the reorganization of cognitive-communicative abilities after brain injury. Such interventions would require clinicians to use the principles outlined here to enrich communicative environments and to target distributed communication in functional systems (not the isolated language of individuals).

RESUMO

For individuals who rely on speech-generating devices (SGDs) to complement and substitute for spoken language, speed, and accuracy of access to the device are paramount for effective communication. There is some evidence that application of motor memory principles may improve effectiveness of SGD-based communication. This article reviews motor learning models and principles, including learning stages, types of practice, and environmental factors that affect learning, and highlights the potential applications of these principles in dynamic display SGD design, intervention, and research.

RESUMO

New technologies designed to improve the communication of autistic children can also help to promote interaction processes and cognitive and social development. The aim of this study was to analyze the instruments used to improve the communication skills of children with autism spectrum disorder. We searched the PubMed and Web of Science databases using the descriptors "autism", "Asperger", "education", "children" and "assistive technology" and selected articles that met the following inclusion criteria: (i) original research; (ii) written in English; (iii) based on participants with a primary diagnosis of autism spectrum disorder; and (iv) tested an instrument designed to promote communication in children with autism spectrum disorder. Our search retrieved 811 articles, of which 34 met the inclusion criteria. Data on 26 instruments were extracted, and the measurement properties of the instruments were combined with information about their outcomes and presentation. The most commonly used interventions were the Treatment and Education of Autistic and Related Communication Handicapped Children program and the Picture Exchange Communication System. The Treatment and Education of Autistic and Related Communication Handicapped Children program was shown to produce improvements in the communication skills, socialization and self-care skills of children with autism spectrum disorder. The Picture Exchange Communication System produced inconsistent results. The results of the identified studies confirm the significant importance of these instruments in improving the communicative process of autistic children.
