Phenotypical heterogeneity in language abilities is a hallmark of autism but remains poorly understood. The present study collected naturalistic language samples from parent-child interactions. We quantified verbal abilities (mean length of utterance, tokens, types) of 50 Chinese-speaking children (M = 5; 6) and stratified subgroups based on their…

Early diagnosis of autism spectrum disorder (ASD) in children enables earlier access to services and better ability to predict subsequent development. A vast body of literature consistently shows discrepancies in the age of diagnosis between children from varying socio-economic levels, cultural and ethnic backgrounds. The present study examines…

This study aimed to compare symptoms of autism spectrum disorder using the Childhood Autism Rating Scale (CARS) and the Social Responsiveness Scale (SRS™-2) and to investigate their influencing factors. The diagnostic agreement was 92.7%, but with a fair Kappa value (0.247). Children's verbal comprehension was related to the CARS scores, and no…

In the present study we aim at providing further evidences for the validity of an initiation processes impairment in autism spectrum disorder (ASD). We applied different verbal fluency tasks designed to decrease or enhance this limitation. A group of high-functioning individuals with ASD and a group of typically developed individuals matched for…

With Latent Class Analysis applied on data of 98 children with autism spectrum disorder (ASD) (9-12 years; 17 girls) participating in social skills training (SST) in a randomized controlled trial (Dekker et al. 2019), four subgroups were detected, based on social-communicative skills before, and response patterns to training. Two subgroups…

Gesture comprehension remains understudied, particularly in children with autism spectrum disorder (ASD) who have difficulties in gesture production. Using a novel gesture comprehension task, Study 1 examined how 2- to 4-year-old typically-developing (TD) children comprehend types of gestures and gesture-speech combinations, and showed better…

Approximately 30% of school-aged individuals with autism spectrum disorder (ASD) are nonverbal (that is, they have little or no spontaneous spoken language). Most reading tests require verbalisation, which may under-estimate reading ability in this group. To determine decoding abilities of nonverbal children with ASD (with an age range of 72 to…

Few interventions exist for school-aged minimally verbal children with autism spectrum disorder (ASD). Even though play skills are associated with children's production of language, few studies have focused on play for minimally verbal children. Fifty-eight minimally verbal children with ASD received a naturalistic developmental behavioral…

Proficient use of spatial terms such as "under," "to the left of" or "in front of" is a central component of daily communication and is important in the development of language and spatial cognition. Here we examine spatial language abilities in intellectually high-functioning individuals with autism spectrum…

Background: Many children with autism spectrum disorder (ASD) demonstrate verbal communication disorders reflected in lower verbal than non-verbal abilities. The present study examined the extent to which this discrepancy is associated with atypical speech sound differentiation. Methods: Differences in the amplitude of auditory event-related…

Objectives: The study aimed to examine the ability of children with an Autism Spectrum Condition (ASC) to depict social (pride and shame) vs. basic (happiness and sadness) emotions in their human figure drawings. Methods: Eleven children with a formal diagnosis of an ASC matched on gender and verbal mental age with 11 children with typical…

Individuals with autism often exhibit atypical levels of attention to eyes. High support need and minimally verbal individuals with autism have typically received less attention in research. This study explored a preference based computer game to include the less-studied individuals with autism in their own school environment. Four high support…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

Background: Problems with pragmatic aspects of language are well attested in individuals on the autism spectrum. It remains unclear, however, whether figurative language skills improve with language status and whether problems in figurative language are no longer present in highly verbal individuals with autism. Aims: To investigate whether highly…

Researchers have proposed that autism spectrum disorder (ASD) is characterized, at least in part, by executive function (EF) difficulties associated with the integrity of the frontal lobe. Given the paucity of research regarding EFs in young adults with high functioning ASD (HF-ASD), this research involves an examination of various indices of EF…
