Abstract: The visual design elements and principles (VDEPs) can trigger behavioural changes and Citation: Cabrera, F.E.; emotions in the viewer, but their effects on brain activity are not clearly understood. In this paper, Sánchez-Núñez, P.; Vaccaro, G.; we explore the relationships between brain activity and colour (cold/warm), light (dark/bright), Peláez, J.I.; Escudero, J. Impact of movement (fast/slow), and balance (symmetrical/asymmetrical) VDEPs. We used the public DEAP Visual Design Elements and dataset with the electroencephalogram signals of 32 participants recorded while watching music Principles in Human videos.
