Moving Backgrounds Draw Children Back to Screens, ISB Study Finds
ISB research shows animated backgrounds attract attention, but children focus more on visuals than on instructors
Hyderabad: Moving backgrounds in children’s videos can bring wandering eyes back to the screen faster, but the additional attention may not be directed at the lesson itself, according to a study co-authored by an Indian School of Business (ISB) professor.
The study, ‘Attention Trap? How Visual Motion Shapes Children’s Screen Time and Engagement on Video Platforms’, published online in September in ‘Information Systems Research’, found that visual motion was associated with higher viewership. In an eye-tracking experiment, children exposed to videos with moving backgrounds spent less time looking away from the screen, but much of their additional on-screen attention went to the background rather than the instructor.
“The interesting finding is where that additional attention goes. Children were not spending significantly more time looking at the instructor. Much of the additional attention was directed towards the moving background,” said Prof. Madhu Viswanathan, associate professor of marketing at ISB and one of the study’s authors.
The findings raised a question for parents and digital platforms — did keeping children watching necessarily mean they are learning more? The researchers examined more than 32,000 videos from 93 popular YouTube channels designated as made for children. After accounting for other characteristics, including audio, visual and emotional features, they found that a 10 per cent increase in visual motion was associated with approximately one per cent more views.
Prof. Viswanathan cautioned that this did not mean children spent 1 per cent more time on screens. Views and total screen time were different measures. Even a small increase could have sizeable consequences at scale. For a video with one million views, a one per cent increase represented 10,000 additional views.
The team then conducted a field experiment using professionally produced educational videos. The presenter, narration and lesson remained the same, while animated stars were added to the background at different speeds. The videos were shown through randomised YouTube advertising campaigns.
Compared with the version without added motion, the medium-motion video recorded a 1.6 per cent increase in view rate, while the high-motion version recorded a 2 per cent increase. The experiment supported the finding that background movement itself could influence viewing behaviour.
A third study examined the mechanism behind this effect. Fifty-three children aged six to 10 participated in an eye-tracking experiment. The researchers found that visual motion did not prevent children from looking away. Instead, it shortened the duration of prolonged periods when their attention was off-screen.
“This was perhaps the most interesting finding for us. Motion does not appear to hold children’s attention continuously. Children still look away. What changes is how quickly their attention returns,” Prof. Viswanathan told Deccan Chronicle.
The study did not measure whether children understood or retained more of the lesson. The researchers examined viewing behaviour and attention, not learning outcomes.
Prof. Viswanathan said it was plausible that a child could watch an entire educational video without necessarily learning more. To establish whether motion helped or distracted from learning, future research would need to compare animations that directly explain a concept with unrelated background movement and simpler visuals, while testing comprehension and retention.
For parents choosing educational videos, he advised focusing on whether or not the visuals helped explain the subject rather than how exciting the screen appeared. An animation demonstrating how the heart pumped blood or how planets moved could serve a teaching purpose, while movement added merely to keep the screen visually stimulating may not.
“More animation is certainly not necessarily better,” he said. The experiment did not find correspondingly larger gains in attention as background motion increased from medium to high levels.
