There is no known cause, but genetic factors appear to be significant. Current prevalence is estimated at one in about every 88 children and it is four to five times more common in boys than girls. The prevalence of ASD has increased significantly over the past 20 years, owing in part to a broader definition and improved diagnostic practices. A review of this type is intended to highlight the major emerging research trends in the field and advance evidence-based practice with respect to the provision of AAC intervention to individuals with ASD and intellectual disability and severe communication impairment.ĪSD is a neurodevelopmental disorder associated with persistent deficits in social communication and social interaction, restricted interests, and repetitive behavior. In light of this need, the aim of this paper is to review two current and major research trends related to designing and implementing effective AAC intervention for individuals with ASD and intellectual disability and severe communication impairment.

Instead, there is typically a need for systematic, and often intensive, intervention to ensure the person learns how to use AAC for functional communication. It is generally not enough to simply provide the person with an AAC system. For such persons, a critical part of the AAC process is to design and implement evidence-based interventions. Severe communication impairment is prevalent among individuals with autism spectrum disorder (ASD) and intellectual disability. The term severe communication impairment is used in situations where the person’s speech is too limited and/or too unintelligible to provide an effective means of communication.

Aided AAC may be indicated when the person lacks sufficient motor control for using gestures and manual signs or when the person must communicate with listeners who do not understand sign language.ĪAC is indicated for individuals who present with severe communication impairment or complex communication needs. Another type of aided AAC system is the use of electronic speech-generating devices. For example the person might use an alphabet board to spell out a message or select graphic symbols (e.g., line drawings or photographs) from a picture board. Aided AAC, in contrast, requires external materials or equipment. Unaided AAC is considered for individuals with sufficient motor control to produce the required gestures/manual signs and when communicating with listeners who can interpret the person’s gestures/manual signs. Such modes are considered unaided because communication with them does not require any external materials or equipment. Unaided modes include the use of gestures and manual signs. Specific modes within this range have been classified as either unaided or aided.
Ī range of non-speech communication modes have been evaluated in AAC research and implemented in clinical practice. AAC systems are also often used to augment unintelligible speech.
Clinical practice in AAC is largely concerned with enabling people with limited speech and language to communicate using one or more alternatives to speech. AAC research has covered a wide range of topics from developing new and more effective methods of implementing AAC, to investigating the effects of AAC use, to evaluating innovative assistive communication technologies. Augmentative and alternative communication (AAC) refers to an area of research and clinical specialization that spans several disciplines, including: (a) assistive technology, (b) psychology, (c) rehabilitation, (d) special education, and (e) speech-language pathology.
