Transcript

  • 1. Emotion and EmbodimentOn the Role of Emotion in Embodied Cognitive Architectures: from Organisms to Robots- Tom Ziemke, Robert Lowe (2009) DongNyeok Jeong
  • 2. Emotion and Cognition• Emotion 1. A natural instinctive state of mind deriving from ones circumstances, mood, or relationships with others. 2. Any of the particular feelings that characterize such a state of mind, such as joy, anger, love, hate, horror, etc.• Cognition 1. The mental process of knowing, including aspects such as awareness, perception, reasoning, and judgment. 2. That which comes to be known, as through perception, reasoning, or intuition; knowledge.
  • 3. Introduction• Closely connected to embodied cognition• Grounded in homeostatic bodily regulation• A powerful organizational principle— affective modulation of behavioral and cognitive mechanisms—that is ‘useful’ in both biological brains and robotic cognitive architectures
  • 4. Introduction• Historical background• Amygdala (1) How stimuli acquire emotional properties (2) How emotion influences the formation and recollection of episodic memory (3) Emotion’s influence on attention and perception, facilitated by the amygdala’s extensive connectivity with sensory processing regions (4) The recognition of emotional facial expressions (5) The influence of higher cognitive functions on emotional processing
  • 5. Introduction• ‘‘mechanisms of emotion and cognition appear to be intertwined at all levels,’’• ‘‘understanding of human cognition requires the consideration of emotion.’’
  • 6. Organisms and Emotions in Cognitive ScienceDamasio and Panksepp
  • 7. Organisms and Emotions in Cognitive Science• Internal Robot • The inside of the body of organisms and to study the interactions of the robot’s control system with what is inside the body• Basic Emotions • anger, disgust, fear, happiness, sadness, surprise • Limbic emotional action system
  • 8. Organisms and Emotions in Cognitive Science • its role in the behavioral organization of individual agents (attention, learning, action selection, decision-making), rather than the ‘external’ aspects of emotion (expression and recognition) involved in social coordination and communication.
  • 9. Who needs Emotion, and What for?• Emotional systems enable animals to more effectively explore and interact with their environment, eat, drink, mate, engage in self-protective and defensive behaviors, and communicate.• Each emotion is both an internal body monitor and a detector of dangers, threats, losses, or other matters of concern.
  • 10. Who needs Emotion, and What for?• “As-if body loop” • A neural internal simulation• “emotions cannot be seen as mere ‘coloration’ of the cognitive agent, understood as a formal or un- affected self, but are immanent and inextricable from every mental act.’’
  • 11. Emotion in Embodied cognition architecturesDamasio Prescott TJ et al., control architectures in robots and vertebrates
  • 12. Emotion in Embodied cognition architecturesBased on LeDoux JE., Emotion circuits in the brain. Pessoa’s conceptual proposal
  • 13. Emotion in Embodiedcognition architectures • dopamine : working memory systems essential for linking emotion, cognition and consciousness • serotonin : among other functions, behavioral state regulation and arousal, mood, motor pattern generation, learning and plasticity • opioids : responses to pain and stress, endocrine regulation and food intake
  • 14. Embodied cognitive-affective architecture
