Understanding Partner Selection for Cooperation

Cooperation and cooperative social relationships are the cornerstone of human social success and well-being. The puzzle of our cooperative psychology has been a topic of interest for many decades. In recent years, this puzzle has become relevant in computational fields, given the rapid development of artificial intelligence. Research efforts in this area envision AI systems as recommenders or social catalysts. While these applications have shown promise in enabling humans to reflect on their behavior during meetings, their utilization in everyday social interactions remains limited. Extending the usability of such systems can help people to reflect on their behavior in social interactions or how they select partners for cooperation. Thus, the main proposition of Tiffany Matej Hrkalovic's thesis is that before we design such systems, we must first expand our understanding of how people initiate cooperative behavior and select partners for cooperative interactions.

People want partners who are high on warmth and competence when selecting partners. However, this relationship is dependent on specific tasks, where people prefer warmer partners when warmth is important for a task, while they prefer competent partners in tasks where a partner's competence is more important. Additionally, people are more cooperative towards partners they select and want to interact with, compared to partners they don't want to interact with. However, people are not very good at selecting partners who will cooperate back when selecting partners in real-life interactions. Matej Hrkalovic tested these research questions in real social interactions and purely non-interactive settings. Lastly, she also shows how people think and describe their relationships can help predict their prosocial and punishment behavior towards their relationship partners.

AI systems are growing in popularity, yet they remain limited in their ability to support human decision-making in social interactions. Matej Hrkalovic's thesis addresses that gap by exploring key social phenomena involved in how people choose partners for cooperation. It provides empirical resources and a dataset to support modeling efforts in this area. Her research offers valuable contributions to both psychology and human-AI interaction, presenting insights that can inform future studies in both disciplines.
