Using abstract concepts (e.g., "freedom") is one of the most sophisticated abilities humans possess. In this conference, some of the leading scientists in the field propose novel perspectives on abstract concepts, their acquisition, representation, and use. The first session is dedicated to the influence of inner speech and language on abstract concepts use and representation. The second session focuses on novel interactive methods to investigate abstract concepts and on abstract concepts variability across cultures and languages. Finally, the third session addresses the role of sensorimotor and interoceptive, emotional, and metacognitive aspects on abstract concepts acquisition, representation, and use.
