There are many aspects of individuals that make them attractive or unattractive to others. Similarity in values, beliefs, needs, and personality, as well as physical attractiveness, are some of the most common attractive characteristics (Woodall, Burgoon, & Markel, 1980). However, at the first meeting, especially in public settings, there is often little transparency between individuals. Initial impressions made here cause individuals to form expectations of future encounters, and thus influence the nature of subsequent social interactions (Riggio & Friedman, 1985). Research has examined aspects of preferred-sex attraction (Feinman & Gill, 1977) that suggest that males find light hair and eyes more attractive in females. In contrast, they found that women prefer dark hair and dark eyes in men (Feinman & Gill, 1977). Because the face is the primary focus during interpersonal communication (Riggio & Friedman, 1985), we were led to ask whether the type of smile exhibited by a person would influence attraction to the opposite or preferred sex. The eyes are the primary facial region showing differences between genuine and forced smiles (Frank, Ekman, & Friesen, 1982). Based on this study and facial behavior studies conducted by French anatomist GB Duchenne, two major muscle groups illustrate the distinction between genuine and non-genuine smiles. Forced or posed smiles activate the zygomaticus major muscle, the muscle that primarily controls the cheeks, while genuine smiles are also said to cause a contraction of the orbicularis oculi muscle that surrounds the eye (Boraston, Corden, Miles, Skuse and Blakemore, 2007 ). Additionally, the outer part of the orbicularis oculi, which causes the skin outside the eye to pinch... center of paper... male participants found men in red shirts significantly more attractive than the same men in a white shirt. shirts. Furthermore, when asked, study participants reported not knowing the nature or purpose of the experiment, suggesting that color has the power to influence opinions on a subconscious level. A similar study showed that red, as the color of sex and romance, increases women's attractiveness (Elliot & Niesta, 2008). Men in this study rated women in red higher in terms of perceived physical attractiveness and sexual attraction, which includes both initial attraction and potential romantic interest. Our research aims to explore the effects of smile type and background color on attraction. Based on available research and theory, we hypothesize that models with genuine smiles and red backgrounds will be perceived and rated as more attractive.
