ฎ ⾐࡮ዊ ᎨCommunications Training Applying AAC to a Child WithDown's Syndrome
KOGA,Seiji and KOMINE,Sachiko㧚

Abstract
This paper is a case study on a child with Down's Syndrome, whohas difficulty verbally expressing her emotions and ideas, despite
possessing a high level of language comprehension.

She was not only

instructed on how to improve her oral communication skills, She was also
introduced to a method in which she could communicate using pictures.
In order to test this method, pictures of toys from the preschool she
attends were used as well as her favorite toys.

Careful observation of achange in her speech pattern and behavior allowed me to witness animprovement in her voluntary communication skills.
