The present study was realized starting from research on emotion pro- cesses related to moral reasoning in cyberbullying, using a task of emotion attrib- ution (i.e., positive and negative emotions) to a fictional cyberbully and a fic- tional cyber victim. Specifically, we investigated whether the involvement in cyberbullying or in cyber victimization was associated with differences in the emotion attribution task. 528 middle school students (282 girls, mean age = 12.58 years, DS = 1.16 years) took part in the study. The results of a MANOVA showed that youths perpetrating cyberbullying, compared to non-involved peers, at- tributed higher positive emotions and lower negative emotions to the fictional cyberbully. Moreover, youths involved in both cyberbullying and cyber victimi- zation (i.e., the so-called cyberbully-victims) compared to pure cyber victims had higher likeability to attribute positive emotions to a fictional cyber victim. The findings were discussed in light of the role of morality and moral disengagement in both traditional bullying and cyberbullying research, expanding the role of emotion attribution beyond moral emotions. Furthermore, the importance of care- fully considering cyber victims’ impairments in emotion attribution processes as possible risk factors for the development of a cyberbully-victim condition was advanced.

Even if research has shown some differences between cyberbullying and traditional bullying (i.e., direct, verbal and rela- tional bullying acted in face-to-face contexts), both phenomena are proactive forms of
