  1. Emotions in IDA

  2. Why emotions? • Emotions can get you into a lot of trouble. Think about all the trouble emotions are! • Our anger is something that we must almost always keep in check. • And fear. We always have to fight fears to accomplish worthwhile goals. e.g. Overcome the fear of speaking. • We have to fight feelings of envy, jealousy. • We have to fight discouragement. • It usually is not a complement to be called an emotional person. Synonyms from Roget's Thesaurus include temperamental, volcanic, touchy, excitable, irritable, sensitive, explosive, edgy, high-strung.

  3. Why emotions? (cont.) • Why do we fight these emotions? • They influence actions • We just don’t like them

  4. Emotions vs. Feelings • Emotions are the primary motivators • Well, not really emotions – feelings • Emotions are feelings with a cognitive component • What • Why • Where • Etc.

  5. Original implementation for IDAused these four primitives Primitive emotions • Common theory suggests that all emotions are combinations of six primitives • Happiness • Sadness • Anger • Fear • Disgust • Surprise

  6. Primitive feelings • The primitive emotions model is not complete • Why would a computer or robot have the same emotions or feelings as a human • Rather than primitive emotions based on humans, we use primitive feelings which may change between different agents • Some primitive feelings do not have a cognitive component – but do have consequences

  7. In IDA • Emotion/Attention codelets recognize some state or stimuli • Each codelet embodies some feeling about the current situation • Based on the intensity of the recognized stimuli/state, the codelets send activation to associated codelets (behavior, perception, other emotion, etc.) and modify the drives and the gain

  8. Associations • Most associations with emotion codelets are designed-in • Others accrue based on Pandemonium • Facilitates learning to anticipate emotional triggers

  9. Emotional memory • The network of emotion codelets feeds into (and out of) four codelets that represent the four basic emotions used previously • The values of these four are stored in long-term memory • A returned memory may have emotional values returned with it • The returned values directly effect the four primitive emotion codelets • The primitives then propagate activation to other emotion codelets which may effect the drives or even behaviors

  10. How does that make you feel? • The four emotion codelets representing the four emotion primitives are gross approximations and mainly kept for backward compatibility • The emotional state (or how the agent feels) is a combination of ALL of the primitive emotion/feeling codelets that directly sample the world/agent-state and those that directly effect the drives or behaviors

  11. Phenomenality • Once again, this is a functional model • It does not say anything about the phenomenality of experiencing feelings or emotions
