The Effect of High-tech AAC System Position on the Joint Attention of Infants without Disabilities

Abstract

Joint attention is critical for language development in children. Children with complex communication needs have additional challenges in managing their joint attention, and there is minimal information on how to reduce these demands. Sixteen infants without disabilities and their caregivers participated in a within-subjects design with two storybook reading interactions. In reading, the researcher either held a high-tech AAC system directly in front of herself (aligned with eye-gaze) or to the side (divided from eye-gaze). The frequency and duration of coordinated and passive joint attention episodes were analyzed. The aligned condition resulted in significantly greater frequency and duration of coordinated joint attention than passive joint attention in episodes involving the AAC system. Age was significantly related to frequency and duration of joint attention only in the aligned condition. Future directions and clinical implications are discussed.
