This experimental study extends conflict elaboration theory (1) by revealing social influence dynamics for a knowledge-rich computer-supported socio-cognitive conflict task not investigated in the context of this theory before and (2) by showing the impact of individual differences in social comparison orientation. Students in two conditions (N = 59) compared their self-created task solution with a partly correct solution presented additionally, deviating from their solution. The other solution's source was introduced either as a low status source ("peer") or as a high status source ("textbook") whereas the presented solution was identical. In a baseline condition, this comparison possibility was missing. Students in the textbook condition experienced more socio-cognitive conflict and adapted their solution more often to the correct aspect of the presented solution than students in the peer condition. Students low in social comparison orientation adapted their solution more extensively in the textbook condition than in the peer condition.
