Edgar Rubin was appointed professor and head of the Department of Psychology at the University of Copenhagen in 1922, establishing the foundation of the Copenhagen School of Phenomenology. This influential research tradition remains active within the Department of Psychology at the University of Copenhagen today, alongside other psychological approaches. The present volume offers the first comprehensive collection of the key insights from this tradition. By publishing this work, the editors aim to introduce these ideas to a broader audience and highlight the essential role of phenomenology in advancing psychological research.
