Study Summary
This study uses mobile eye-tracking technology in order to characterize patterns of visual attention to communication supports, as well as a partner, within real world interactions for individuals with Down syndrome. Visual communication supports are central components of what is termed augmentative and alternative communication (AAC) intervention. AAC refers to the methods and technology designed to supplement spoken communication for people with limited speech. "Aided" AAC is a subcategory in which an external aid stores and presents for use visual symbols such as photographs, line drawings, or alphabet letters. The most traditional means of structuring aided AAC displays is to present the language concepts within row-column grids, which contain individual symbols/concepts placed in each grid square. The investigator's previous work investigated whether these grid-based presentations could be improved by understanding how different perceptual features of the displays influence responding (i.e., whether what the display looks like influences how easily the information on it is found). Individuals with developmental disabilities and children developing typically were faster and more accurate in finding information on some displays over others, when tested using a "visual search" task (aka, a "finding game" - "find the dog"). The previous investigations have evaluated visual attention within a setting that isolated visual processing of the AAC display as the primary dependent measure. However, communication requires attention not only to an AAC display, but also to a communication partner. Therefore, the current study seeks to examine questions of visual attention to both an AAC display and a communication partner. The investigators will manipulate characteristics of the structure of the display (e.g., arrangement of symbols), in order to determine if more optimal displays facilitate desirable patterns of visual attention to both the communication display and the p
Primary Outcome
Measured through percent of fixation time allocated to (a) the AAC display; (b) the storybook, or (c) the communication partner. Percent is calculated by dividing the total number of samples within each area (AAC display, storybook, partner) into the total number of samples obtained by the eye tracking device.
Interventions
- DEVICE AAC Technology - Standard of Care
- DEVICE AAC Technology - non-optimal integrated arrangement
