The original version of this Article contained a typographical error in the spelling of the author Sergi Bermúdez i Badia which was incorrectly given as Sergi Bermdez i Badia. Furthermore, the affiliation for Paul Verschure and Zenon Mathews was incorrectly given as, Institute of Audio-Visual Studies, University Pompeu Fabra, Barcelona, Spain rather than, Laboratory of Synthetic Perceptive, Emotive and Cognitive Systems, ICREA-UPF, Barcelona, Spain. Both these errors have now been corrected in the Article.
