Learning Disabilities

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Area of Science:

Augmentative and Alternative Communication (AAC)

Background:

Rett syndrome presents significant communication challenges.
Effective communication interventions are crucial for this population's standard of care.

Purpose of the Study:

To evaluate an intervention package for teaching aided communication requests.
To assess the effectiveness of the intervention for two individuals with Rett syndrome.

Main Methods:

Within-participant, adapted multiple baseline design across items/activities.
Graphic mode requests on speech-generating devices were taught.
Access methods included touchscreen and eye-gaze, tailored to motor abilities.

Main Results:

The intervention package increased the accuracy of independent request selection responses.
The number of sessions to reach performance criteria varied between participants.
Prompting and prompt fading presented challenges, particularly with eye-gaze.

Conclusions:

Aided communication interventions are effective for teaching requesting skills to individuals with Rett syndrome.
Findings have implications for communication intervention methods for severe communication impairment.
Future research should explore diverse communication intervention options.
