Emotions as directed affect +Modulation

Examples:

Fear:anticipation of aversive events (à neg.valence)+arousalAnxiety:uncertainty (à neg.valence)+low competence +arousal,highsecuring behavior (frequent background checks)



Examples:

Anger:Perceived obstacle (usually agent)manifestly prevented reachingof anactive,motivationally relevantgoal (àneg.valence),sanctioningbehavior tendency (à goal relevance is re-directed to sanctioning ofobstacle),arousal,low resolution level,highaction readyness,highselection threshold

Sadness:Manifestprevention from all conceived ways of reachingactive,relevantgoal,without relevantobstacle (à neg.valence),support-seeking behavior (by increased demand for affiliation),low arousal,inhibition of active goalà decreased action readyness



Examples:

• Pride:highcompetence (à low securing rate),highinternal legitimacy,likely coincidence with highexternallegitimacy

• Joy:higharousal +highperceived reward signal fromsatisfying ademand

• Bliss:low arousal +highperceived reward signal fromsatisfying ademand (since physiological demands ofteninvolve higharousal,mostly related to cognitive demands,suchas aesthetics)

• Motivationparameters:Personalityproperties• Modulationparameters:Temperament


IndividualVariations by Parameterizing

Possible grounding of personality properties (FFM):• Openness:appreciation of art and new ideas,curiousity

• Conscientiousness:rulefollowing vs.chaotic• Extraversion:tendency to seek stimulation byenvironment and others

• Agreeableness:tendency for cooperativeness andcompassion

• Neuroticism:emotionalstability,effect of failureto self-confidence

Thank you!

Interesting questions:

• Is recursive function approximation plusmotivationalsystem sufficient for generalintelligence?

• Could we functionally recreate human-likemindswith our model?

• How does amotivated/emotionalsystem evolvewhen it can modify itself?
