About Nils Frederik Tolksdorf

I am a researcher in the area of children's language development and learning with digital technologies. I completed my Ph.D. within the Digital Society Research Program, funded by the State of North Rhine-Westphalia, Germany, under the supervision of Prof. Dr. Katharina Rohlfing. My research lies at the intersection of psycholinguistics and child–robot interaction, with a focus on language learning. I am experienced in language acquisition research, with a particular focus on multimodality, cross-situational word learning, and pragmatics. Regarding social robotics, my experience focuses on dialogue design, ethical and child-oriented implementation of the technology, and how temperamental traits influence children's interaction behavior with social robots.

Project merits (2018–2022): Early childhood media interaction and language learning with social robots to promote participation opportunities in the digital society

In this project, child-robot interaction is investigated from the perspectives of media pedagogy and psycholinguistics: How to design a child-oriented dialogue? Can preschoolers' language development benefit longitudinally from an interaction with a robot? What do kindergarten teachers expect from a child-robot interaction? The project addresses the need to introduce digital technology to children in order to foster equality in digital society.
