How multitasking during video content decreases ad effectiveness: The roles of task relevance, video involvement, and visual attention

Abstract: In a 3 (secondary task: none, related, unrelated) x 2 (ad-video congruence: high/low) between-subjects eye-tracking experiment, participants (N = 151) watched a 9-minute video documentary segment containing one mid-roll video ad while their visual attention to the screen was recorded. Participants in two-thirds of the conditions also read two online articles on a mobile device during the video. Results show effects for both multitasking and task relatedness on attention to the ad and attitudes toward the ad, through distinct pathways.
