Evidence shows that traditional marketing campaigns are becoming less effective. Given this, a series of initiatives have been undertaken with the objective of increasing the efficiency of advertising and ensuring the strengthening of brands before their potential consumers. The search for objective measures of consumer behavior has led in recent years to a growing effort to employ neuroscience concepts and methods in marketing, with the aim of favoring the improvement of advertising, since neuroscience concepts and methods can measure objective variables until then captured only through subjective reports. Emotions have long been known to have an important effect on consumer behavior, and consumers have affective relationships with their brands and products. However, it has been found that so far no study has investigated whether the induction of incidental emotions could have any effect on the level of visual attention in advertising, and this was precisely the purpose of this thesis. Three independent groups were constituted, with 20 individuals each. Each group was induced to neutral, joy and fear and then the level of visual attention was observed through, eye tracking equipment, in ten beer advertising stimuli. The results revealed that induction of joy increased visual attention to brand, products and human faces within advertisements, while induction of fear produced the opposite effect. The implications of these findings for advertising strategies are discussed.
