Judicious Arrangement of Symbols on a Simulated Augmentative and Alternative Communication Display Optimizes Visual Attention by Individuals With Down Syndrome.
Article in Journal of speech, language, and hearing research : JSLHR, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAided augmentative and alternative communication (AAC) displays are often designed as symmetrical row-column grids, with each square in the grid containing a symbol. To maximize vocabulary on displays, symbols are often placed close to one another, and background color cuing is used to signal/differentiate symbols across different grammatical categories. However, from a visual and developmental standpoint, these display features (close-set symbols and use of background color cues) may not be optimal. In particular, placing symbols quite close together may result in visual crowding, in which individual symbols cannot be distinguished due to the presence of many neighbors, or flankers. This research sought to examine the role of display arrangement and background color cuing on the efficiency of visual attention during search.
methodTen adolescents and adults with Down syndrome underwent a visual search task while a research-based eye tracking system recorded their patterns of visual attention. Participants searched for symbol targets on displays with varying levels of visual crowding and background color cuing.
resultsSpatial arrangements that reduced visual crowding and that used the spatial organization to cue the grammatical category of symbols resulted in significantly fewer fixations to nonrelevant distracters during search and reduced the likelihood of fixations away from the target once it was located. Background color was helpful in reducing the latency to find the target. DISCUSSION: Spatial cues may offer a powerful means to maximize the efficiency of search within AAC displays. Background color cuing may facilitate speed to locate targets in these older individuals. Implications for AAC design, as well as future avenues for maximizing (growing) vocabulary, are discussed.
