B. Paired Sample T-Tests ine, and trustworthy.¹º In the present study, it is possible that the advertisers’ genuine smile inspired a sense of trust and positivity in the participants viewing the product, leading to higher product quality ratings in the smiling condition. On the other hand, a fake smile only involves the zygomatic major muscle.¹¹ The data shows that consumers can subconsciously observe the difference between a genuine and false smile and be affected differently. In the present study, it appears that participants differentially responded to a genuine versus fake smile as their product quality ratings and price ratings differed. It was hypothesized that adolescents would pay a greater amount than adults for the same product due to their lack of experience earning and spending money. The results of this study surprisingly showed that the adolescents overall had a lower evaluation of the product. For both product quality and preferred pricing for all three facial expressions, adolescents, on average, gave a lower rating or price for each category compared to adults. For adolescents, the greater the susceptibility to interpersonal influence, the greater the tendency to buy on impulse.¹² Therefore, when shown a model with a genuine smile, adolescents were more willing to pay a higher price and give the product a better evaluation, which is also demonstrated by the results. However, adolescents were significantly less influenced by a false versus a real smile when pricing the product compared to adults. On average, adults were willing to pay about 14.6% more when the model had a real smile while adolescents were willing to pay about 9.12% more. This can be attributed to the lack of exposure of adolescents to spending, which results in an unformed understanding of the value of money. Part of this study involved having participants imagine that this was a real product being sold. In other words, they had to envision that this still face on the screen was associated with selling this white t-shirt. Perhaps adults were better able to envision this scenario, while adolescents struggled to make this link. Adults: To further explore the results from the ANOVA analysis, paired sample t-tests were used to determine which facial expression conditions were in fact statistically different. According to the results of the Paired Sample T-Test, adults’ ratings of quality across a neutral face and fake smile (p < 0.00001) as well as across a neutral face and real smile (p < 0.001) were both statistically significant. On the other hand, adults’ ratings across a fake smile and real smile were not statistically significant (p = 0.54). The adults’ ratings of product pricing across a neutral face and fake smile (p < 0.002), neutral face and real smile (p < 0.003), and fake smile and real smile (p < 0.03) were all statistically significant. Adolescents: According to the results of the Paired Sample T-Test, adolescents’ ratings of quality across a neutral face and fake smile (p < 0.006) as well as across a neutral face and real smile (p < 0.02) were both statistically significant. On the other hand, adolescents’ ratings across a fake smile and real smile were not statistically significant (p > 0.05). Adolescents’ ratings of product pricing across a neutral face and fake smile (p < 0.0002), neutral face and real smile (p < 0.0002), and fake smile and real smile (p < 0.04) were all statistically significant. These findings support previous research on emotional contagion in which happiness exemplified by the advertiser evokes that same emotion in the participants. In all cases, adolescents and adults were on average willing to pay more and had a significantly higher evaluation of the quality of the product when the advertiser was smiling rather than displaying a neutral facial expression. The results show that participants placed higher evaluation scores when presented with an advertiser with a genuine smile. To explain these results, we turn to previous studies, which have revealed that the muscular contractions involved in smiling and fake smiling can actually underlie how a viewer regards the expression and how positive emotions are transferred.8-9 With a genuine smile, the zygomatic major and orbicularis oculi muscles in the face are contracted. As a consequence, people tend to intuitively evaluate a smiling facial expression as authentic, genu- IV. CONCLUSION In conclusion, consumers are willing to pay more and tend to have a higher evaluation of the quality of a product when a model in an advertisement displays a real smile, instead of a fake 44
