This paper presents a systematic literature review of the literature on productive dialogues and emotional aspects in Computer-Supported Collaborative Learning (CSCL) and also presents emotional aspects used in debates with conflicting points of view in other contexts. Initially, more than 400 articles were catalogued, belonging mainly to the databases of Springer and Science Direct, not limited by years, because of very important works referenced until today. The findings reveal that in CSCL there is a neglect in relation to the emotional dimension, the results also show that there are negative emotional aspects that impair the motivation in the participation of students in collaborative activities. Empathy is seen as an alternative to conflict resolution in different contexts, in addition to collaborative learning, but it is rarely addressed in CSCL.
