This project concerns itself with the social factors that contribute to the minimal self. From a developmental perspective, it focuses on parent-child interaction patterns and attachment representations. The project consists of four studies that rely on experimental, cross-sectional, and longitudinal designs, and are carried out with preschoolers and adults. Interdisciplinary cooperations with colleagues from cognitive science and robotics are established, and allow for a modelling approach to the empirical results. Overall, the project applies an attachment-theoretical focus and aims at characterizing the nature and extent of social influences on the developing minimal self.
