    A simple Call Aid device helped adolescents with trainable intellectual disabilities improve their telephone dialing skills. This low-cost tool significantly enhanced independence for individuals with visual sequencing and memory challenges.

    Area of Science:

    • Assistive technology
    • Developmental disabilities
    • Rehabilitation engineering

    Background:

    • Individuals with visual sequencing deficits and impaired immediate memory often struggle with independent task completion, such as making phone calls.
    • Independent living skills are crucial for individuals with intellectual disabilities, yet specific challenges can hinder their acquisition.
    • Existing assistive tools may not adequately address the combined needs of visual sequencing and memory impairment for telecommunication tasks.

    Purpose of the Study:

    • To evaluate the effectiveness of a novel, low-cost assistive device, the Call Aid, in enabling independent telephone use.
    • To assess the ability of trainable mentally handicapped adolescents to learn and retain telephone dialing skills using the Call Aid.
    • To provide a practical, easily constructible solution for individuals facing challenges with sequential memory and visual organization.

    Main Methods:

    • A pre-test, post-test study design was employed to assess the impact of the Call Aid intervention.
    • Ten adolescents with trainable intellectual disabilities (IQ range 40-55) participated in the study.
    • Training involved using the Call Aid, a device constructed from spiral-bound cards, to facilitate telephone number sequencing and dialing.

    Main Results:

    • Nine out of ten participants successfully dialed a telephone independently immediately following training.
    • The positive results were sustained, with nine participants still able to dial successfully one week after the initial training.
    • The study demonstrated a significant improvement in the independent telephone-making ability of the participants.

    Conclusions:

    • The Call Aid is an effective and inexpensive assistive tool for individuals with visual sequencing and immediate memory impairments.
    • This intervention significantly enhances the independence of trainable mentally handicapped adolescents in performing essential daily living tasks like making phone calls.
    • The simple construction and demonstrated efficacy suggest the Call Aid's potential for broader application in supporting individuals with cognitive and memory challenges.
