To endow virtual agents with more human-like behaviour, the current project proposes a new model for decision making based on emotions and trust. The project focuses first on the conceptual design of the model, then on the implementation of this model. To try to reproduce human decision making, the model has, mostly, been based on psychologically grounded findings. This model is based on the BDI structure, and has been extended with submodels for emotions and trust. To further prove the implementability of the model, it was implemented first at a conceptual level - in LeadsTo, and thereafter in the RoboCup soccer environment. The implementation in LeadsTo shows exactly how the connections and information flows of the model work. The generated results show that agents that use a decision model where emotions are included perform different actions than agents using the model without emotions. To investigate these results further, and in a more dynamic environment, the model was then successfully implemented in the RoboCup soccer environment, 2D simulation. Some of the results were significant differences in actions between players with different goals, and differences insome of the performed actions between a positive versus a negative emotional team.
