People are very precise in the discrimination of a line orientation relative to the cardinal (vertical and horizontal) axes, while their orientation discrimination sensitivity along the oblique axes is less refined. This difference in discrimination sensitivity along cardinal and oblique axes is called the "oblique effect." Given that the oblique effect is a basic feature of visual processing w...

Previous research has demonstrated that the conditional-only method (starting with a multiple-stimulus array) is more efficient than the simple-conditional method (progressive incorporation of more stimuli into the array) for teaching receptive labeling to children with autism spectrum disorders (Grow, Carr, Kodak, Jostad, & Kisamore,). The current study systematically replicated the earlier st...

Autism Treatment Trust, a charity dedicated to helping individuals with autism reach optimal health and learning, provides access to diagnostic, medical and behavioural services. Treating Autism, a charity run entirely by volunteers, provides information and support to families and individuals affected by autism with the aim of improving their quality of life. charities, nor individual contribu...

The Autism Spectrum Quotient is used to assess autistic spectrum traits in intellectually competent adults in both the general population and the autism spectrum community. While the autism spectrum Quotient has been validated in several different cultures, to date no study has assessed the psychometrics of the Autism Spectrum Quotient on an Australian population. The purpose of this study was ...

A range of educational/treatment approaches is currently available for young children with autism spectrum disorders (ASD). A recent comprehensive review by an expert panel on ASD (National Research Council, 2001) concluded that a number of approaches have demonstrated positive outcomes, but nonetheless, not all children benefit equally from any one approach. Efforts to increase communicative a...

Our understanding of ASD has changed over the past decades, and diagnostic tools have assisted in earlier identification and referral for intervention. Appropriate intervention appears to impact positively on overall outcome for a pervasive developmental disorder for which there is currently no known cure. Novel and controversial therapies will come and go, and therefore physicians should famil...

Although researchers have examined barriers to implementing evidence-based practice (EBP) at the level of the individual, little is known about the effects workplaces have on speech-language pathologists' implementation of EBP. The aim of this study was to examine the impact of workplace factors on the use of EBP amongst speech-language pathologists who work with children with Autism Spectrum D...

This article describes the relationship between expressive communication impairments and common challenging behaviors in individuals with Autism Spectrum Disorder and Intellectual Disability. The communication challenges of individuals with Autism Spectrum Disorder/Intellectual Disability are described and several evidence-based intervention strategies are proposed to support communication so a...

CONTEXT Genetic factors play an important role in the etiology of both autism spectrum disorders and autistic traits. However, little is known about the etiologic consistency of autistic traits across levels of severity. OBJECTIVE To compare the etiology of typical variation in autistic traits with extreme scoring groups (including top 1%) that mimicked the prevalence of diagnosed autism spec...
