This study investigates the interaction effect between relative performance feedback and levels of task interdependence in group settings. Although a negative effect of relative performance feedback has been signaled in previous studies for agents´ performance at team level due to the sucker effect. This study suggests that this effect is moderated by the level of task interdependence. An experiment was run with two independent variables: the presence of RP (vs. absent), and three type of tasks (additive, disjunctive and conjunctive, which represent three different levels of interdependency at team level). Our results show that the lower the level of interdependency, the greater the negative effect of RPF in group settings. Interesting and contrary to previous studies, we found a positive effect or RPF in group settings, under conjunctive tasks.
