Advertising is evolving at a steady pace, and the challenges that it is facing are significantly different from what they used to be. Nevertheless, an initial advertising goal, the one that precedes any future goal, attracting consumers’ attention, remains the same. The consumer attention is being refered to as the gatekeeper for higher order advertising outcomes. Advertisers’ aim is, thus, effectively attract consumers’ attention and guide it towards their message. Relationship between the advertisement presentation and these higher order advertising outcomes, such as positive feelings towards the product, brand loyalty, actual purchase, etc. is rather small. Especially compared to other promotional and contextual factors such as inertia, loyalty and prior purchases which explain almost two thirds in the variability of consumer behavior in markets. The sheer amount of events transpiring between the advert presentation and the consumers’ behaviour can confound the total advertising effects. For this reason, it is marketers’ goal to positively influence each event under their direct control, and advertisement design is certainly one of them. The present research continues on the abundance of research aimed at discovering how to most effectively attract consumers’ attention which started in the 1990s. Such studies report that consumers are attending to advertisements differently based on their involvement with the brand, brand attitude and ad recall ; that advertisement’s property to effectively hijack viewers’ attention and increase the future ad recall is related to advert being perceived as obtrusive and distracting and ; that three factors thought to influence consumers’ allocation of attention to ad processing aside from the task at hand are consumers’ motivation, opportunity and ability. Throughout the previous period, various ad design characteristics have been tested for their attention attracting properties including advertisement’s size, number of letters and clearance from the road., etc. Surprisingly, despite the fact that more than half of all the advertisements show human face in them, the human face has not received enough researchers’ attention, as it did consumers’. This practice has been related with an easier advertisement recall and more positive attitudes and purchase intentions according to scarce literature on the matter. However, even those researches that did explore human face in advertising context, have not focused on the factors influencing face’s ability to automatically attract attention, nor what happens with consumers’ attention once it is captured by the human face in advert. Through the course of the dissertation it will be argued that potential mechanisms through which human face is efficient in attracting consumers’ attention towards the ad are the model’s eye gaze and emotional expression. Eyes are regarded as one of the most important social stimuli capable of expressing complex mental states such as beliefs, desires and emotions. Thus, we will argue that this evolutionary importance of attending and recognizing another’s gaze direction can be utilized as the way of either attracting attention to the ad itself, or to guide attention towards the specific ad element (to which the model is gazing at). Much like eye gaze, facial expression of emotion is a primary channel through which individual is expressing his emotional state. Following the same rationale, people have evolved mechanisms for quick detection and recognition of emotional expressions, since it was preferential for an individual to give themselves enough time to prepare for the possible fight or flight when confronted with an individual expressing anger, for example. Final factor being researched through the course of the present thesis is the consumers’ cognitive load. It is almost impossible to research advertisement without including consumers’ cognitive resources which are more readily invested in other activities than to advertisement. This problem has been emphasized by the proliferation of the new media channels which has led to consumers being exposed to a huge amount of advertisements presented simultaneously through different channels. Each of these stimuli is competing for the same resource, consumers’ attention. To test whether advertisements’ efficiency can be enhanced by the use of the evolutionary important social stimulus, such as human face, and how is this relationship dependent on the consumers’ cognitive load, two studies were designed. In each study, one type of cognitive load was manipulated. By increasing the complexity of the scene in which the advertisement stimuli were presented, external cognitive load (i.e. the amount of information presented in the visual field) is manipulated, and its effect on attention is examined for different types of advertisement stimuli. Participants’ internal cognitive load was manipulated in the second study by involving them with a memory task in which they are required to memorize a short (low load) or a long (high load) digit string for the duration of the study. This time, we had tested how does the ad design affect not only attention to advertised product, but also how the advertisement is perceived by the consumer depending on the different mental effort involved with advertisement processing. Results confirmed predictions from the evolutionary psychology that human face’s importance can be used as a way of increasing advertisements’ attention grabbing efficiency, but also the attitudes toward the presented ad. Possible reason for such finding is the ease with which the face is being processed and perceived due to its evolutionary importance which has made the face prioritized by humans’ cognitive system. Most importantly, we have gained a support for the observation that faces can be also used to point viewer’s attention to the certain place where the key advertisement message, or product is presented on advert. The mechanism through which the face acts as the efficient attention grabber is the increased saliency of the ad. When the advertised product’s saliency is significantly higher than the saliency of the surrounding stimuli, all other design characteristics are less important. This can be achieved in a number of ways, such as by varying the product’s colour, luminescence, size, orientation, etc. However, when the advertised product, or an ad itself does not automatically pop-out from its surrounding, consumers’ attention is being guided by the stimuli which are preferentially searched for, for example human face making the advertisement containing it more salient compared to its surrounding. Model’s emotional expression (happiness) significantly increased advertisements’ saliency, resulting in shorter search times compared to other emotional expression and other cue types. The same emotion was positively related with the ad evaluation. Eye gaze effect was not as strong as the emotional expression, although some reduction in time needed for reacting to a presented product was observed, effect was rather small. Finally, internal cognitive load, unlike the external one, was not associated with attention (i.e. reaction time) needed for clicking the advertised product. Instead, internal cognitive load had a significant effect on ad evaluation phase, with ads being perceived more positive when consumers had more of their cognitive resources at their disposal (low internal load).
