The background music-content congruence of TV advertisements: A neurophysiological study

[EN] Music affects viewers¿ responses to advertisements. In this study we present the findings of an experiment that investigates the emotional and cognitive reactions of subjects¿ brains during exposure to television advertisements with music congruent, and incongruent, with the advertisement content. We analyze the electroencephalography signals and eye-tracking behaviors of a group of 90 women watching six TV advertisements. The study's findings suggested that incongruent music generates higher levels of attention and advertisement recall. On the other hand, frontal asymmetry measured through electroencephalography was shown to be higher with congruent music. Similarly, cognitive workload was higher when the music was incongruent with the advertisement content. No significant differences were found in terms of advertisement likeability based on incongruent versus congruent music. The results demonstrated the validity of neurophysiological techniques for assessing the effects of levels of music congruence in advertisements.Ausin, JM.; Bigné, E.; Marín-Morales, J.; Guixeres Provinciale, J.; Alcañiz Raya, ML.

Do You See What I See? Effectiveness of 360-Degree vs. 2D Video Ads Using a Neuroscience Approach

[EN] This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versionsThis work was supported by the Generalitat Valenciana funded project "Rebrand", grant number PROMETEU/2019/105, and by the European Regional Development Fund program of the Valencian Community 2014-2020 project "Interfaces de realidad mixta aplicada a salud y toma de decisiones", grant number IDIFEDER/2018/029.Ausin-Azofra, JM.; Bigné, E.; Ruiz, C.; Marín-Morales, J.; Guixeres Provinciale, J.; Alcañiz Raya, ML.
