Recommendations made by expert groups are pervasive throughout various life domains. Yet not all recommendations--or expert groups--are equally persuasive. This research aims to identify factors that influence the persuasiveness of recommendations. More specifically, this study examined the effects of decisional cohesion (the amount of agreement among the experts in support of the recommendation), framing (whether the message is framed as a loss or gain), and the domain of the recommendation (health vs. financial) on the persuasiveness of the recommendation. The participants consisted of 1,981 undergraduates from Arizona State University. The participants read a vignette including information about the expert group making a recommendation--which varied the amount of expert agreement for the recommendation--and the recommendation, which was framed as either a gain or loss. Participants then responded to questions about the persuasiveness of the recommendation. In this study, there was a linear main effect of decisional cohesion such that the greater the decisional cohesion of the expert group the more persuasive their recommendation. In addition, there was a main effect of domain such that the health recommendation was more persuasive than the financial recommendation. Contrary to predictions, there was no observed interaction between the amount of decisional cohesion and the framing of the recommendation nor was there a main effect of framing. Further analyses show support for a mediation effect indicating that high levels of decisional cohesion increased the perceived entitativity of the expert group--the degree to which the group was perceived as a unified, cohesive group¬--which increased the recommendation's persuasiveness. An implication of this research is that policy makers could increase the persuasiveness of their recommendations by promoting recommendations that are unanimously supported by their experts or at least show higher levels of decisional cohesion.

In the modern age, where teams consist of people from disparate locations, remote team training is highly desired. Moreover, team members' overlapping schedules force their mentors to focus on individual training instead of team training. Team training is an integral part of collaborative team work. With the advent of modern technologies such as Web 2.0, cloud computing, etc. it is possible to revolutionize the delivery of time-critical team training in varied domains of healthcare military and education. Collaborative Virtual Environments (CVEs), also known as virtual worlds, and the existing worldwide footprint of high speed internet, would make remote team training ubiquitous. Such an integrated system would potentially help in assisting actual mentors to overcome the challenges in team training. ACLS is a time-critical activity which requires a high performance team effort. This thesis proposes a system that leverages a virtual world (VW) and provides an integrated learning platform for Advanced Cardiac Life Support (ACLS) case scenarios. The system integrates feedback devices such as haptic device so that real time feedback can be provided. Participants can log in remotely and work in a team to diagnose the given scenario. They can be trained and tested for ACLS within the virtual world. This system is well equipped with persuasive elements which aid in learning. The simulated training in this system was validated to teach novices the procedural aspect of ACLS. Sixteen participants were divided into four groups (two control groups and two experimental groups) of four participants. All four groups went through didactic session where they learned about ACLS and its procedures. A quiz after the didactic session revealed that all four groups had equal knowledge about ACLS. The two experimental groups went through training and testing in the virtual world. Experimental group 2 which was aided by the persuasive elements performed better than the control group. To validate the training capabilities of the virtual world system, final transfer test was conducted in real world setting at Banner Simulation Center on high fidelity mannequins. The test revealed that the experimental groups (average score 65/100) performed better than the control groups (average score 16/100). The experimental group 2 which was aided by the persuasive elements (average score 70/100) performed better than the experimental group 1 (average score 55/100). This shows that the persuasive technology can be useful for training purposes.
