Concepts are the building blocks of knowledge. We study how new concepts are learned and how these concepts are rooted in perception. We are also interested in how concept formation and problem solving interact.

More broadly, the lab works on

  • Perception & Psychophysics,
  • Concepts & Categories,
  • and Reasoning & Problem Solving.

Our general approach is to try and combine insights from experimental psychology and artificial intelligence (machine learning in particular) to build models of higher cognition.

The lab is associated with the Centre for Cognitive Science and the AI initiative at TU Darmstadt.
