The implications and benefits of signaling goes beyond the academic aspect of understanding content; it also creates presentations which are easier on the eye, more coherent in their messaging, and more simplistic in the presentation’s aesthetic. For example, one aspect of signaling in visual content involves highlighting critical information the learner should prioritize in their understanding of the new material, as shown in Figures 1a and 1b (DeBell, 2020).

Signaling also allows for an experience that relieves clutter from the learner’s perspective. For example, in Life Noggin’s Why Do You Sleepwalk? video, a graph appears showing all stages of the sleep cycle while the narrator explains how the process begins. The REM cycle’s placement on the chart is highlighted throughout the entirety of this section as it represents the required prior-understanding for the information about to be introduced. The narrator begins to introduce new information relating to the graph detailing stages 3 and 4 of the sleep cycle. While the concept of those stages are being verbalized, the text “Stage 3” and “Stage 4” bounces in a way to draw the viewer’s attention to what’s being verbalized (See figure 2). Within seconds, at 0:28, the dialogue shifts to focus on what processes take place in the brain during those stages. As the narrator transitions, so does the animation, as the focus of the video brings us as viewers into the figure’s head to see a representation of a human brain appear. Despite all of the information presented in just a matter of seconds, the focus on critical information remains steady in focus.
