WPM and 220- WPM captioning. But for segments with captions, the preponderance of eye gaze dominated at the bottom of the screen. The addition of captions apparently turns television viewing into a reading task, since the subjects spend most of their time looking at captions and much less time examining the picture. Rather interestingly, subjects were re-tested with the same videos a few days later. Subjects spent slightly more time looking at the picture than reading captions.
Viewers read the caption and then glance at the video action after they finish reading.
We have evidence here that viewers of all stripes tend to spend most of their time watching captions. As we see from this study, captions technically are distracting. However, the purpose of captions is to be read. Undistracting captions are failed captions. Moreover, we do not have any evidence of understanding of the program, or retention.
