Schema of the agent-based model of emotion dynamics [11,47]. The internal state of an agent is composed of valence v and arousal a, and the communication through the online medium is quantified by the field h. Valence and arousal change according to a combination of internal eigendynamics and perception dynamics, the latter depending on the field h. Expression s is triggered by production rules depending on the emotional state of the agent. Expression changes the field and leads to a feedback of expression that regulates the emotions of the agent.
