Recent studies reveal that tonal language speakers with autism have enhanced neural sensitivity to pitch changes in nonspeech stimuli but not to lexical tone contrasts in their native language. The present ERP study investigated whether the distinct pitch processing pattern for speech and nonspeech stimuli in autism was due to a speech-specific deficit in categorical perception of lexical tones. A passive oddball paradigm was adopted to examine two groups (16 in the autism group and 15 in the control group) of Chinese children's Mismatch Responses (MMRs) to equivalent pitch deviations representing within-category and between-category differences in speech and nonspeech contexts...

AIM: To assess the performance of a newly designed, culturally adapted screening tool for autism spectrum disorder (ASD). METHODS: Items for the screening tool were modeled from already documented checklists and diagnostic criteria for ASD. Each item in text was paired with a photograph that illustrated the written content, which was in the 2 main local languages. The final product had 21 items and was named the pictorial autism assessment schedule (PAAS). Performance of PAAS was tested on a clinical sample of 18-48 mo old children, diagnosis naïve, presenting with developmental deficits...

The production of specific mental state terms types and functions by caregivers and their TD children and caregivers and their children with ASD were assessed in two contexts: a parent's story-telling task and a child's story-telling task. Caregivers of children with ASD produced less causal talk and proportionally less desire and cognitive talk than did caregivers of TD children. When focusing only on variation in our ASD sample, caregivers' and children's production of different mental state references varied with context and were predicted by different child characteristics (i...

This paper aims to explore the connection between health and developmental disorders, particularly in regard to the notion of 'neurodiversity', which considers high-functioning autism not as a lifelong disability but a neurological form within a diversity of human minds. In recent years, autistic activist movements have called for a more positive, humanizing, identity-first language when describing this condition, rejecting negative language such as 'disorder', 'deficit', and 'impairment', and instead describing autism as a way of being, part of one's personal identity, which does not always need to be cured...

Purpose: This research explored syntactic growth in children with fragile X syndrome (FXS) over a 5-year period, and variability in growth in relation to autism symptoms, nonverbal cognition, maternal responsivity, and gender. Method: Language samples at 4 time points from 39 children with FXS, 31 boys and 8 girls, were analyzed using the Index of Productive Syntax (Scarborough, 1990) and mean length of utterance (Brown, 1973). The degree of autism symptoms was evaluated using the Childhood Autism Rating Scale (Schopler, Reichler, & Renner, 1988) at the first time point...

BACKGROUND: Understanding how emotional faces are processed is important to help characterize the social deficits in Autism Spectrum Disorder (ASD). AIMS: We examined: (i) whether attention is modulated by emotional facial expression; (ii) the time course of the attentional preferences (short vs. long stimulus presentation rates); and (iii) the association between attentional biases and autistic symptomatology. METHOD AND PROCEDURES: We applied a dot-probe experiment with emotional faces (happy, sad, and angry)...

INTRODUCTION: Children with autistic spectrum disorder (ASD) often have associated behavioural difficulties that can present a challenge for parents and parenting. There are several effective social learning theory-based parenting programmes for dealing with behavioural difficulties, including the Incredible Years (IY) parent programmes. However, these programmes typically do not specifically target parents of children with ASD. Recently, a new addition to the IY suite of programmes known as the IY Autistic Spectrum and Language Delays (IY-ASLD) parent programme was developed...

Autism spectrum disorder (ASD) is a developmental disorder that significantly impairs patients' ability to perform normal social interaction and communication. Moreover, the diagnosis procedure of ASD is highly time-consuming, labor-intensive, and requires extensive expertise. Although there exists no known cure for ASD, there is consensus among clinicians regarding the importance of early intervention for the recovery of ASD patients. Therefore, to benefit autism patients by enhancing their access to treatments such as early intervention, we aim to develop a robust machine learning-based system for autism detection by using Natural Language Processing techniques based on information extracted from medical forms of potential ASD patients...

BACKGROUND: Minimal literature exists regarding Autism Spectrum Disorder (ASD) among refugee children in the United States. Reliable ASD screening tools, such as the M-CHAT-R/F, have yet to be culturally adapted and translated into some languages spoken in the homes of these children. METHODS: Pediatric refugee patients (n = 13) of caregivers of Bhutanese (Nepali-speaking) descent were screened using a newly translated Nepali M-CHAT-R/F. The M-CHAT-R/F was adapted based on feedback from Bhutanese caregivers and interpreter expertise...

Purpose: Research into how bilingual parents of children with autism spectrum disorder (ASD) make choices about their children's language environment is scarce. This study aimed to explore this issue, focusing on understanding how bilingual parents of children with ASD may make different language exposure choices compared with bilingual parents of children without ASD. Method: Semistructured qualitative interviews were conducted with 17 bilingual parents with a child with ASD and 18 bilingual parents with a typically developing (TD) child...

Autism Spectrum Disorder (ASD) has been associated with abnormal synaptic development causing a breakdown in functional connectivity. However, when measured at the macro scale using resting state fMRI, these alterations are subtle and often difficult to detect due to the large heterogeneity of the pathology. Recently, we outlined a novel approach for generating robust biomarkers of resting state functional magnetic resonance imaging (RS-fMRI) using connectivity based parcellation of gross morphological structures to improve single-subject reproducibility and generate more robust connectivity fingerprints...

Early intensive behavioral intervention (EIBI) and its recent variant, naturalist developmental behavioral intervention (NDBI) aim to increase socialization and communication, and to decrease repetitive and challenging behaviors in preschool age autistic children. These behaviorist techniques are based on the precocity and intensity of the intervention, face-to-face interaction, errorless learning, and information fragmentation. Once considered to be "scientifically proven", the efficacy of these approaches has been called into question in the last decade due to poor-quality data, small effects, low cost-efficiency, and the evolution of ethical and societal standards...

BACKGROUND: Language is a highly lateralized function, with typically developing individuals showing left hemispheric specialization. Individuals with autism spectrum disorder (ASD) often show reduced or reversed hemispheric lateralization in response to language. However, it is unclear when this difference emerges and whether or not it can serve as an early ASD biomarker. Additionally, atypical language lateralization is not specific to ASD as it is also seen more frequently in individuals with mixed- and left-handedness...

There is some statistical evidence indicating that Somali refugees and immigrants have high rates of autism spectrum disorder (ASD). Somalis in North America call autism the "Western disease" because there is no word for autism in the Somali language and because many believe it does not exist in Somalia. In Toronto, Somali parents have forged an "epistemic community," united around a coherent theory of the development of autism, its defining features, and most successful therapies. They work together with researchers to support the theory that gut bacteria is a causal factor for the development of autism...

Joint attention skills have been shown to predict language outcomes in children with autism spectrum disorder (ASD). Less is known about the relationship between joint attention (JA) abilities in children with ASD and cognitive and adaptive abilities. In the current study, a subset of items from the Autism Diagnostic Observation Schedule (ADOS), designed to quantify JA abilities, were used to investigate social attention among an unusually large cross-sectional sample of children with ASD (n = 1061). An examination of the association between JA and a range of functional correlates (cognitive and adaptive) revealed JA was significantly related to verbal (VIQ) and non-verbal (NVIQ) cognitive ability as well as all domains of adaptive functioning (socialization, communication, and daily living skills)...

A large cohort consisting of all children born to mothers from community provides 'natural' selection into different exposures and is a powerful resource for epidemiological research. A large population-based birth cohort with detailed systematic information already recorded, as part of longitudinal medical care, historical and current school data, detailed birth certificate data and all three resources available for every member of the birth cohort, are extremely rare. Our population-based birth cohort consists of all children born between 1976 and 2000 to mothers residing in Olmsted County, Minnesota, at the time of child's birth (N=39 890)...

Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency, consistency, and productivity of past, present, and future usage, using the Speechome Recorder, which enables collection of dense, longitudinal audio-video recordings of children's speech...
