For years, emotions have been widely considered in the areas of negotiation and conflict resolution. Standard methods of negotiation have dealt with the individuals' arousal and expression of a vast array of emotional states. If we consider ODR as a communicative process involving a group of individuals engaged in an interactive decision-making task, we will need to admit that emotions are an essential component in any online disputing process. This paper proposes a review of recent literature on emotions and ODR to discuss controversial issues such as the capacity of ODR techniques to deal with emotions and the advantages and disadvantages of computer-mediated communication versus face-to-face communication in terms of expressions of emotions.
