AAC Interventions for Autism

In the realm of autism communication, AAC (Augmentative and Alternative Communication) interventions play a vital role in supporting individuals with autism who have difficulty with verbal speech. These interventions encompass various modalities that can replace or augment a person's speech and existing communication skills. Two key AAC interventions for individuals with autism include teaching request making and supporting language development.

Teaching Request Making

AAC interventions have proven to be effective in teaching children with autism to make requests and reducing challenging behaviors. The Picture Exchange Communication System (PECS), aided AAC, and speech generating devices (SGD) have shown the most evidence of effectiveness in this area [7].

The PECS involves using a series of pictures to enable individuals with autism to initiate communication by exchanging a picture card with a communication partner, indicating their request or desire. This intervention empowers individuals to make their needs known and promotes functional communication skills.

Aided AAC refers to the use of external aids, such as communication boards or electronic devices, to support communication. These aids can include symbols, pictures, or words that individuals can use to express their requests. By using aided AAC, individuals with autism can communicate their needs effectively and engage in meaningful interactions.

SGDs, or speech generating devices, are electronic devices that produce synthesized or recorded speech. These devices give individuals with limited or no speech the ability to generate spoken language by selecting symbols or typing on a keyboard. SGDs offer a powerful tool for individuals with autism to express themselves and engage in conversations.

Supporting Language Development

AAC interventions also play a significant role in supporting ongoing language development for individuals with autism. These interventions provide additional supports for comprehension and help extend language skills, even for those who are developing spoken language abilities [7].

AAC strategies can include incorporating different modalities, such as signs and symbols, to enhance language comprehension and expression. By using various visual and auditory cues, individuals with autism can better understand and communicate their thoughts, ideas, and feelings.

Moreover, training individuals in the child's social environment, such as family members, teachers, or peers, to support the use of AAC can facilitate language development. By creating a supportive and inclusive communication environment, individuals with autism can practice and reinforce their language skills in real-life situations.

It is important to individualize AAC interventions to meet the specific learning needs and preferences of children with autism. This may involve incorporating different modalities of AAC, such as signs and symbols, and training individuals in the child's social environment to support the use of AAC. Early consideration of AAC interventions within a comprehensive intervention program is crucial, and further research is needed to explore the broader outcomes and effectiveness of AAC interventions for children with autism.
