“…Relevant is also the increased prevalence of absolute pitch and musical savants in the ASD population (e.g., DePape et al 2012;Heaton et al 2008a, b, c;Miller 1989;Mottron et al 2013) and the increased prevalence of autistic traits among possessors of absolute pitch (e.g., Dohn et al 2012). The occurrence of this superior pitch processing contrasts with the inferior temporal processing abilities in ASD (such as impaired gap-in-noise detection, duration discrimination, temporalenvelope processing, temporal order judgement; e.g., Alcántara et al 2012;Bhatara et al 2013;Kwakye et al 2011;Lepisto et al 2005Lepisto et al , 2006Samson et al 2011; but see Jones et al 2009;Kasai et al 2005) and the evidence of speech perception impairments (Alcántara et al 2004;Bhatara et al 2013;Groen et al 2009) and generally delayed speech and language development (e.g., Anderson et al 2007). Speech perception has been shown to be particularly impaired while presented in noise with temporal dips (Alcántara et al 2004;Groen et al 2009) or in a competing talker condition (Alcántara et al 2004;Bhatara et al 2013).…”

We investigated low-level auditory spectral and temporal processing in adolescents with autism spectrum disorder (ASD) and early language delay compared to matched typically developing controls. Auditory measures were designed to target right versus left auditory cortex processing (i.e. frequency discrimination and slow amplitude modulation (AM) detection versus gap-in-noise detection and faster AM detection), and to pinpoint the task and stimulus characteristics underlying putative superior spectral processing in ASD. We observed impaired frequency discrimination in the ASD group and suggestive evidence of poorer temporal resolution as indexed by gapin-noise detection thresholds. These findings question the evidence of enhanced spectral sensitivity in ASD and do not support the hypothesis of superior right and inferior left hemispheric auditory processing in ASD.

“…Pragmatic language impairments are considered universal to ASD (Tager-Flusberg & Joseph, 2003); however, there is substantial heterogeneity in the extent of structural language difficulties that co-occur with ASD (Ellis Weismer & Kover, 2015;Tager-Flusberg, Paul, & Lord, 2005;Tek, Mesite, Fein, & Naigles, 2014). Some individuals have well preserved (or even superior) structural language abilities on formal testing, with sophisticated vocabulary and sentence structure (Boucher, 2012;Tager-Flusberg & Caronna, 2007), yet studies of individuals ascertained through population-based or clinical samples have found between 25% and 30% of children with ASD are minimally verbal or nonverbal (Anderson et al, 2007;Norrelgen et al, 2014). These estimates may vary according to age, the definition of minimally verbal or nonverbal used and the way the sample was ascertained.…”

Background: Language difficulties are common in autism spectrum disorder, yet little is known about the prognosis of language in children with autism spectrum disorder. The aim of this study was to systematically review studies reporting language outcomes in individuals with autism spectrum disorder. Method: A comprehensive search strategy with a well-established sensitive prognosis filter for Medline, adapted for five other databases, was used. Included studies observed individuals diagnosed with autism spectrum disorder for !12 months and had !30 participants. Risk of bias was assessed. Results: Fifty-four studies (N ¼ 5064) met inclusion criteria. Language outcomes were standardised assessments (n ¼ 35), notation of presence/absence of verbal language (n ¼ 11) or both (n ¼ 8). Age at baseline ranged from 17 months to 26 years, duration of follow-up from 1 to 38 years. Most publications (92%) were rated medium to high risk of bias. In all but one study individuals had below-average scores at baseline and follow-up. However, in most (n ¼ 24/25; 96%) studies reporting standard scores, individuals (aged 11 years at follow-up) progressed at a comparable rate to age-expected norms or demonstrated some 'catch up' over time. Meta-analyses found mean standard scores increased over time in three language domains (composite receptive language, composite expressive language and adaptive language). Nineteen to thirty percent of children aged five years and under gained verbal language. For children aged over five years 5-32% gained verbal language over the course of study. Age, baseline language scores, IQ and length of followup did not moderate between study differences in composite language or adaptive language growth or the acquisition of verbal language. Conclusion: Despite variability in study methods, findings were consistent, with the majority of studies reporting children under 11 years on average progressed at a comparable rate to age-expected norms or with some 'catchup' over time. Implications: This review provides synthesised information for families and clinicians on language development over time and on language outcomes for individuals with autism spectrum disorder. Such information can be useful for prognostic counselling and may assist planning around future resources and support needs. This review also makes recommendations regarding methodology for future studies so that prognosis can become more fine-tuned at an individual level.

“…Clear parallels between social communicative development and general development or language development, as sometimes suggested by other findings (e.g., Charman et al, 2000;Stone, Ousley, & Littleford, 1997; for findings of no clear relation between amount of change in social communicative development and change in language, see Anderson et al, 2007) were not so apparent at the individual level. For example, some non-ASD cases with low DQs performed at least average on imitation tasks, while other cases with ASD, a high DQ, and above average language skills performed rather poorly on pretend play tasks.…”

While impairments in joint attention, imitation, and pretend play are well documented in children with autism spectrum disorder (ASD), the developmental trajectories of these symptoms remain unknown. The main objective was to explore these trajectories in a sample of children at risk for ASD between the ages of 2 and 4 years. After screening positive for ASD, 17 children were prospectively followed with 6-monthly assessments of social communicative skills and general development.During this study, 9 children were diagnosed with ASD. Results showed that there was growth in imitation skills and in pretend play ability. Also, a slightly increased amount of initiation of joint attention was noted. However, the quality of joint attention behaviours did not significantly improve and growth rates did not significantly differ between children with ASD and non-ASD cases. There was a great intra-individual variability, especially in the performances on the imitation tasks. Also interindividual variability was apparent: Some children with ASD showed a delayed development of imitation or pretend play, whereas others had a more clearly deviant developmental profile. The importance of looking at individual trajectories and variability in the study of social communicative development in children with ASD is discussed.
