How do the personality traits affect observational behaviors when judging whether smiles are genuine or not Humansu0027 ability to discriminate a Duchenne (genuine) smile from nonDuchenne (xe2x80x9cpresentedxe2x80x9d) smile attracted scientific interests among various types of smiles. To better understand humansu0027 capability and its mechanisms to discriminate Duchenne and nonDuchenne smiles, we examined peopleu0027s observational behaviors during DuchennenonDuchenne discrimination tasks using an eyetracker. In so doing, we also collected data on participantsu0027 personality traits as some previous studies showed that observational behaviors are strongly influenced by the personality traits of observers. With two Experiment, we found differences in observational behaviors between correct and incorrect discrimination, and that different personality traits were associated with different observational behaviors. However, we did not found any significant relationship between observersu0027 personality traits and judgment accuracies. Thus, although we found differential observational behaviors for correct and incorrect respondents, it seems that these differences were nothing to do with participantsu0027 personality traits.

Let Me Show You Your New Home: Studying the Effect of Proxemicawareness of Robots on Usersxe2x80x99 First Impressions First impressions play an important part in social interactions, establishing the foundation of a personxe2x80x99s opinion about their counterparts. Since interpersonal communication is essentially multimodal, people are judged during first encounters by both their verbal utterances and nonverbal behavior, such as how they utilize eye contact, body distance, and body orientation. In this paper, we argue that robots would provide better user experiences, including being perceived as more likable if they were able to make a good first impression when introduced to a new home. Moreover, we wanted to test if robots can improve their perceived impression by behaving in a proxemicaware manner; i.e., by following established social norms, which prescribe, for example how far people should position themselves around other objects to improve the facilitation of social interactions. In order to test this hypothesis, we conducted a user study with 16 participants in a virtual reality setting, comparing the impression of two agents being introduced to their new homes by users. We found that the proxemicaware agent was indeed perceived as significantly better considering multiple constructs, including perceived anthropomorphism and trustworthiness.
