Emergent Model of Emotion Mei Yii Lim, Ruth Aylett, Christian Martyn Jones Heriot-Watt University
Existing Emotion Models • Inspired by appraisal theory • Focus on agent’s cognitive behavior • Most of these models • simulate a limited picture of the links between lower-level and higher-level functionalities • Trigger expressions according to one emotion
High-cognitive level models • OCC taxonomy – key reference in the domain of ECA • OZ Project • Affective Reasoner • VICTEC, etc • Appraisal Model by Scherer
Low-level models • Cathexis model by Velásquez • Cañamero • etc.
An Emergent Emotion Model • ‘PSI’ model of emotion, by psychologist Dietrich Dörner • Framework for agents • Emotional modulation, perception, action-selection, planning and memory access • Integrated level-bridging model of emotion
Continued … • Emotions emerge from modulation of information processing and action selection • Become apparent when agents reflect their interaction with the environment
Modulators • Each modulators lie within a range of intensity • Resolution level • Selection threshold • Activation • Rate of updating
Built-in motivators • Together with the modulators produce complex behavior • Level of competence • Knowledge • Urgency of motives • Importance of motive • Uncertainty level
Possible advantages • Adaptive agent • Reflect mixture of emotions • For example, gradual change of emotional expression • More colour and variation to the type of emotions that can be experienced
Sample Implementation • The Island Game
