Autistic people who cannot speak risk being underestimated. Their inability to speak, along with other unconventional behaviors and mannerisms, can give rise to limiting assumptions about their capacities, including their capacity to acquire literacy. In this preregistered study, we developed a task to investigate whether autistic adolescents and…

Autism spectrum disorder is a neurodevelopmental condition characterized by social communication difficulties and restricted, repetitive behaviors. Autism spectrum disorder is highly co-morbid with other neuro-psychiatric disorders such as attention deficit hyperactivity disorder, anxiety, and depression. However, research on post-traumatic stress…

Adaptive behavior is paramount for independent living and is varyingly impaired in different neurodevelopmental disorders. This study aimed to investigate differences in adaptive behavior between children with autism spectrum disorder and social communication disorder, two conditions characterized by deficits in social communication. Data from 232…

Echolalia has been described as the repetition of words, phrases, songs or other more elaborate dialogues uttered by another person, which may be immediate or delayed (International Classification of Diseases, 11th Revision; "Diagnostic and Statistical Manual of Mental Disorders", 5th ed.). Some classify echolalia as a communication…

Using language for social purposes can be a real challenge for children with autism spectrum disorder (ASD) and developmental language disorder (DLD). Despite the positive effects of the Pragmatic Intervention Programme (PICP) already known in both populations, the effects needed to be established with a larger sample and analysed separately for…

Naturalistic developmental behavioral interventions are an empirically supported intervention approach for young autistic children. Despite the prevalence of disruptive behaviors among autistic children, most manualized caregiver-mediated naturalistic developmental behavioral interventions include limited formal guidance on when and how to manage…

The "Diagnostic and Statistical Manual of Mental Disorders'" (5th ed.) Social (Pragmatic) Communication Disorder is meant to capture the social elements of communication dysfunction in children who do not meet autism spectrum disorder criteria. It is unclear whether Social (Pragmatic) Communication Disorder captures these elements…

Research ethics is an important part of any study. Ethics goes beyond ethics committee approval and consent documents. It addresses broader issues of respect, inclusion, and empowerment in the everyday context of research. This article focuses on everyday aspects of research ethics for studies involving autistic participants. It draws on a review…

Anxiety is a common co-occurring condition in autism and impacts quality of life of autistic individuals and their families; autistic individuals who speak few or no words represent an under-researched group. This qualitative study aimed to understand more about parental recognition and management of anxiety in autistic individuals who speak few…

Autistic children and adults who are non-verbal/minimally verbal or have an intellectual disability have often been excluded from Autism Spectrum Disorder research. Historical, practical and theoretical reasons for this exclusion continue to deter some researchers from work with this underserved population. We discuss why these reasons are neither…

The Diagnostic Interview for Social and Communication Disorders (DISCO; Wing, 2006) is a standardized, semi-structured and interviewer-based schedule for diagnosis of autism spectrum disorder (ASD). The objective of this study was to evaluate the criterion and convergent validity of the DISCO-11 ICD-10 algorithm in young and low-functioning…

This article reviews research on (a) autobiographical episodic and semantic memory, (b) the self-reference effect, (c) memory for the actions of self versus other (the self-enactment effect), and (d) non-autobiographical episodic memory in autism spectrum disorder (ASD), and provides a theoretical framework to account for the bidirectional…

According to the major classification systems it is not possible to diagnose a comorbid autistic disorder in persons with Rett syndrome. However, this is a controversial issue, and given the level of functioning of persons with Rett syndrome, the autistic disorder is expected to be present in a comparable proportion as in people with the same…

Referential communication was studied in children with autism spectrum disorder (ASD) including children with autism and Asperger syndrome. The aim was to study alternative explanations for the children's communicative problems in such situations. Factors studied were theory of mind, IQ, verbal ability and memory. The main results demonstrated…

The study describes the perspectives of individuals with Asperger syndrome and other autism spectrum disabilities (ASDs) regarding social challenges and supports. Eighteen adults with ASDs were individually interviewed. They were asked to describe their experiences navigating their social worlds, and recommend effective social supports and…
