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.

    (e)motion installation and embodied cognition (e)motion installation and embodied cognition Presentation Transcript

    • (e)motion A collaboration between Jan Klug, Barbara Nordhjem, Bert Otten and Pavlov E-lab Photo: René Passet
    • Brain & body connected
    • Cognition Action Perception Hurley, 1998 Classical sandwich model
    • Ideomotor theory = idea + motor Kunde, Koch, & Hoffmann, 2004 William James, 1890
    • Prinz, 1997 Iacoboni & Dapretto, 2006
    • You think with your face
    • When you smile, you are faster recognizing positive words
    • If you can’t move your face, you are slower reading emotions Niedenthal et al., 2007; Oberman, Winkielman, & Ramachandran, 2007
    • Emotion
    • There are 43 muscles in the face
    • Six basic emotions Facial Action Coding System (FACS); a catalog of action units (Ekman & Friesen, 1976)
    • Darwin - Drawings by mr. Wood (1872)
    • A micro-expression is a brief involuntary facial expression https://mazuzu.com/microexpressions/
    • You can’t hide micro-expressions, they leak out within less that one fifth of a second I did not have sex with that man I did not have sex with that woman I have never used performance enhancing drugs
    • Each emotion is characterized by movement Bassili (1979)
    • Dynamic faces in the brain
    • Social chameleons
    • The process
    • Photo: Bert Otten Jan coding with MaxMSP & OpenFrameworks
    • Tracking movement
    • The face is analyzed in six segments
    • The lines show motion vectors
    • The (e)motion tracker detects changes in the video This method is called optical flow
    • Thank you
