Craving is a strong desire to consume that emerges in every case of substance addiction. Previous studies have shown that eliciting craving with an exposure cues protocol can be a useful option for the treatment of nicotine dependence. Thus, the main goal of this study was to develop a virtual platform in order to induce craving in smokers. Fifty-five undergraduate students were randomly assigned to two different virtual environments: high arousal contextual cues and low arousal contextual cues scenarios (17 smokers with low nicotine dependency were excluded). An eye-tracker system was used to evaluate attention toward these cues. Eye fixation on smoking-related cues differed between smokers and nonsmokers, indicating that smokers focused more often on smoking-related cues than nonsmokers. Self-reports of craving are in agreement with these results and suggest a significant increase in craving after exposure to smoking cues. In sum, these data support the use of virtual environments for eliciting craving. © Copyright 2014, Mary Ann Liebert, Inc. 2014.

In this paper we study the effect of fat content on visual attention and choice of red meat, as well as differences across gender. In an eye-tracking study, conducted with 105 Portuguese meat consumers, we find that fat content has an impact on visual attention, choice reaction time and choice of red meat products. Consumers pay more attention and choose more often meat products with lower fat content. This impact is further gender specific, with female consumers paying more attention and requiring less time to choose meat products with lower fat content. In contract, male consumers pay more attention to red meat products with higher fat content, but spend more time to choose red meat products with lower fat content. We discuss managerial and theoretical implications in relation to marketing of red meat products. © 2016 Elsevier Ltd.
