RT Journal Article SR Electronic T1 How Consumers Process Unexpected Online Advertisements JF Journal of Advertising Research JO J Advert Res FD WARC SP 219 OP 240 DO 10.2501/JAR-2022-015 VO 62 IS 3 A1 Emna Cherif A1 Thierry Baccino YR 2022 UL http://www.journalofadvertisingresearch.com/content/62/3/219.abstract AB Online advertisements compete for consumer attention. This research investigates the effects of unexpected features in advertising such as motion and abrupt onset. The authors used a within-subject design to analyze the effects of three levels of advertising unexpectedness: high versus moderate versus low during both goal-oriented and free-browsing tasks. To that end, they recorded participant eye movements and measured the attitude toward the advertisement format and perceived intrusiveness. Results show that highly unexpected advertisements captured more attention in both tasks. Moreover, low and high levels of advertising unexpectedness attracted more attention in goal-oriented tasks and were associated with a more favorable attitude toward the advertisement and less perceived intrusiveness. The study further discussed theoretical and managerial implications of the findings.
