(e)motion installation and embodied cognition


Published on

Presentation for Science Acts, 8th of May 2014, Aa-church in Groningen

How do we read emotions? How do we use facial movements to communicate? Barbara Nordhjem is doing research in the field of Cognitive Neuroscience. She is studying visual perception and is investigating these questions. She made the installation (e)motion in collaboration with mediaartist Jan Klug and professor of Neuromechanics Bert Otten and will explain how the installation works and was created between art and science.
