The purpose of this study was to gain greater understanding of the potential benefits of assistive technology (AT) devices on young children's social development. Specifically, changes to the quality of the adult/young child social interactions as a function of the child's access to and use of his/her personal AT device was examined. Using a multielement single-case design, the quality of adult/young child social interactions were examined during snack time when the child used his personal AT device; and the adult/young child social interactions were examined when the personal AT device was not available to the child. Results indicate that the quality of caregiver/young child interactions were significantly enhanced when the AT device was utilized by the child. Implications for practice and future research are discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
