The organization and operation of the emotion system is strongly inspired by various theories of emotions in humans. In concert with the robot’s drives, it is designed to be a flexible system that mediates between both environmental and internal stimulation to elicit an adaptive behavioral response that serves either social or self-maintenance functions.
Several theories posit that emotional reactions consist of several distinct but interrelated facets. In addition, several appraisal theories hypothesize that a characteristic appraisal triggers the emotional reaction in a context-sensitive manner. Summarizing these ideas, an “emotional” reaction for robots consists of:
• A precipitating event
• An affective appraisal of that event
• A characteristic expression (face, voice, posture)
• Action tendencies that motivate a behavioral response.
In living systems, it is believed that these individual facets are organized in a highly interdependent fashion. Physiological activity is hypothesized to physically prepare the creature to act in ways motivated by action tendencies. Furthermore, both the physiological activities and the action tendencies are organized around the adaptive implications of the appraisals that elicited the emotions. From a functional perspective, and suggest that the individual components of emotive facial expressions are also linked to these emotional facets in a highly systematic fashion.
