Deception can be detrimental to individual and organizational decision making. Existing research on behavioral cues to deception has focused mainly on monologue and dyadic interaction. No studies have empirically examined the impact of group size on behavioral cues to deception. This study is the first attempt to investigate whether deceivers behave differently in dyads and triadic groups in synchronous computer-mediated communication. The empirical results revealed that cues to deception were contingent on the group size. Compared with truth tellers, deceivers showed a lower level of pleasantness and language complexity only in dyads, whereas a higher level of cognitive complexity and initiation only in triadic groups. Although participation behavior was a significant cue in both groups, its levels of significance was higher in triadic groups than in dyads. This study raises a broad yet critical issue of group effect on deception behavior. It has significant implications for deception detection in computer-mediated communication.

Deception has been an important problem in interactive groups, impeding effective group communication and group work, yet deception detection in such a context remains understudied. Extrapolated from the interpersonal deception theory (IDT) and group composition research in cooperative contexts, this research proposes that group factors, including diversity and familiarity, have influence on the performance of deception detection. The measurement of group performance was not limited to success, as previous deception studies did, but included efficiency as well because it is fundamental to the effectiveness of deception detection. An analysis of data collected from a real-world online community found that behavioral familiarity had a positive effect, and gender diversity had a negative effect, on group success in deception detection. In addition, behavioral familiarity had a negative effect and functional diversity had a positive effect on the group efficiency of deception detection. The findings not only extend IDT in several important ways but also suggest the need to distinguish between noncooperative and cooperative groups, an important theoretical implication for group composition research.

Ours is one such Observation Site.Methods: As part of a novel project, we did not have any previous experience to use as reference. Despite some challenges, we achieved satisfactory outcomes by establishing a stepwise approach to inbound passenger management, including the division of the working area of the Observation Site, dynamic management of the rooms, closed-loop management of the isolated personnel.Results: As of May 14, 2020, a total of 42 Observation Sites were operational in Pudong New Area. The following are the detailed descriptions of our Temporary Medical Observation Site set up and work flow.Conclusion: Early screening of inbound passengers as well as prompt and dynamic management of information about passengers' close contacts play an active role in preventing an influx of cases. As a pilot program, we have a model that is effective despite some limitations.Keywords: COVID-19, observation, pandemic, screening, airport, room
