Agents joining multi-agent systems (MAS) face two significant problems: they do not know who to trust and others do not know if they are trustworthy. Our contribution extends trust and stereotype approaches to use a comparison of agents’ observable features, called tags, as an initial indication of expected behaviour. The results show an improvement in agents’ rewards in the early stages of the...

Emergency evacuations are dangerous situations for both evacuees and first responders. The use of automation in the form of guidance robots can reduce the danger to humans by both aiding evacuees and assisting first responders. This presents an interesting opportunity to explore the trust dynamic between frightened evacuees and automated robot guides. We present our work so far on designing rob...

Mobile agents are a distributed computing paradigm based on mobile autonomous programs. Mobile applications must balance security requirements with available security mechanisms in order to meet application level security goals. We introduce a trust framework to reason about application security requirements, trust expression, and agent protection mechanisms. We develop application security mod...

Précis We vary the ability of robots to mitigate a participant's risk in a navigation guidance task to determine the effect this has on the participant's trust in the robot in a second round. A significant loss of trust was found after a single robot failure. ABSTRACT Objective: This paper explores the impact that a robot's initial performance has on a person's decision to trust the robot later...

Parkinson's disease (PD) is a neurodegenerative disease that affects the motor system and cognitive and behavioral functions. Due to these impairments, PD patients also have problems in using the computer. However, using computers and the Internet could help these patients to overcome social isolation and enhance information search. Specifically, avatars (defined as virtual representations of h...

Neuroeconomics merges methods from neuroscience and economics to better understand how the human brain generates decisions in economic and social contexts. Neuroeconomics is part of the general quest for microfoundations—in this case, the microfoundation of individual decision-making in social contexts. The economic model of individual decision-making is based on three concepts: the action set,...

Swift starting action teams (STATs) are increasingly prevalent in organizations, and the development of trust is often a critical issue for their effectiveness. However, current theory and research do not provide a clear picture regarding how trust toward the team (i.e., the team as the target) is developed in these settings. The primary contribution of this article is to present a theoretical ...

This study investigates initial trust formation with an unknown online company. Based on data collected from 628 respondents, the results indicate significant direct effects for trust in the Internet infrastructure, susceptibility to the social influence of media, and the presence of influential site characteristics, on user willingness to provide personal information to unknown Internet firms....

Studies on the adoption of business-to-consumer e-commerce have not simultaneously considered trust and risk as important determinants of adoption behavior. Further, trust in information technology has not been addressed to a great extent in the context of e-commerce. This research explicitly encompasses the electronic channel and the firm as objects to be trusted in e-commerce. Our conceptual ...
