The main strategy for reducing prejudice is to encourage contact between different groups. This thesis examines a learning process that underlies such contact: instrumental learning. In this process, people learn from the consequences of their behaviour. How does this learning influence what people think of others? The experiments show that people learn not only from what they do, but also from what they do not do—and that these inactions have a negative influence on evaluations. Actions that are rewarded lead to the most positive assessments, and this effect even extends to how quickly people recognise positive emotions in others. Thus, instrumental learning not only influences evaluations but also social behaviour. In addition, information about personal characteristics determines whether someone is included in our decision-making, even when that information is not actually relevant. This effect was not found for information about social groups. The findings of this thesis underscore the negative consequences of inaction, but also the power of positive actions. They offer new insights for interventions that aim to understand and reduce prejudice.","Radboud University, 08 januari 2026","Promotores : Holland, R.W., Veling, H.P.
