The paper presents the main contributions of the research undertaken by the physician and philosopher Annemarie Mol for research in social psychology. In the field of science, technology and society studies, the investigations conducted by the Dutch philosopher represent a practical turn, making a difference in the way in which, traditionally, actor-network theory lies in this field. Mol's research is characterized by the affirmation of practices performative character, which leads her to question the ways of knowing and intervening in social sciences. Finally we discuss the scope of the notions of ontological politics and logic of care to researches in social psychology.
