In this special section we report on the workshop Standards in Emotion Modeling held in August 2011, Leiden, The Netherlands. An important goal of this workshop was to identify challenges related to the development and evaluation of computational models of affective processes. These challenges were approached from a psychological and a computational modeling perspective. In this introduction we present a summary of the results of this week-long workshop. In addition to that, we are proud to present an invited contribution that proposes solutions to several of these challenges. © 2010-2012 IEEE.
