Group decision making: My research interest is concerned with how group members strategically share and use their information in group decision making. I examine the role of cooperation and competition in information withholding and preference confirmation, especially in hidden profiles. The results of our studies support a motivated information processing approach to group decision making.
Egocentric biases in judgment: Recently, I have been interested in how people overestimate similarity with unknown targets in interdependence situations. In this context, my colleagues and I showed that people project more their attributed traits into a target when they anticipate cooperation, rather than competition. We have shown that people project mainly on those traits that ensure positive outcomes thus supporting the hypothesis that projection in cooperation in driven by people motivation to succeed in this situation.
I also investigated whether similarity overestimation leads to illusion of transparency and interpersonal conflicts.
Effort and affective forecasting: We found a positive relation between the effort invested in one activity and the predicted positive affect resulting from the triumph of this activity. This effect is mediated by the perceived quality of this outcome activity.
