Telephone Call Aid for problems of visual sequencing.

People with problems of visual sequencing and impaired immediate memory have difficulty placing telephone calls independently. A Call Aid, created from an inexpensive spiral-bound pad of 3 X 5 inch cards, enabled people with visual sequencing problems to make a telephone call independently. In a pre-test, post-test study, nine of ten trainable mentally handicapped adolescents, IQ range 40-55, were able to dial successfully immediately after training and 1 week later. Construction of the Call Aid is described.
