Mental model for emotion

  1. 1. Mental models accurately predict emotion transitions Mark A. Thornton & Diana I. Tamir (2017) PNAS Shushi Namba
  2. 2. Introduction
  3. 3. Social mind • People are remarkably good at understanding each other, and people can also predict others’ emotion and behavior. Why ?
  4. 4. Proposed mechanism • Emotion transition have some regularity. • High probability: awe (畏敬) → gratitude (感謝) • Low probability: awe (畏敬) → contempt (軽蔑) • Then, people learned these rules based on own experiences, and might be able to gain accurate mental models of others’ emotion transition.
  5. 5. Studies in this article • Study 1-3: the actual rates of transitions between emotions using existing experience-sampling datasets (own experienced and mental models for other people). • Study 4: Markov modeling over a rich sampling over a rich sampling of 60 states + conceptual building blocks of mental models. • Study 5: Tyranny of the majority (数の暴力: 200万) + emphasis on dynamics
  6. 6. Method
  7. 7. Cut it! (too complicated Please check the source article.
  8. 8. Simple Explanation 1 11:30, Happy 14:30, Relaxed Look this transition! (Experience-sampled)
  9. 9. Simple Explanation 2 Look this transition! (Mental model)
  10. 10. Result
  11. 11. Study 1: N = 40, every 3h/d/2weeks
  12. 12. Study 1: Mental model
  13. 13. Study 1
  14. 14. Study 2: N = 40, every 3h/d/2weeks
  15. 15. Study 2: Mental model
  16. 16. Study 2
  17. 17. Study 3: N = 10,723, random timing
  18. 18. Study 3: Mental model
  19. 19. Study 3
  20. 20. There is the strong associations NRMSE = normalized root mean square error in simple regressions with ratings
  21. 21. Conceptual building: Study 4 • Each dimension evaluated in previous studies. • These index explained highly similar transition in specific valence (e.g., negative: angry ⇒ sad) High auto-correlation!
  22. 22. Particular valence is strong
  23. 23. Dynamic? Static? • The above relationships for each dimensional evaluation is Static information and association. ⇒ controlling for the four conceptual dimensions. ⇒ unique knowledge about emotional dynamics: residual accuracy (mean partial ρ =0.10) + statistical significant [95% bootstrap CI = (0.09, 0.11)], with a large standardized effect size (d = 1.51).
  24. 24. Study 5 • Almost results were replicated using the 2 million data from the Experience Project (www.experience project.com).
  25. 25. Discussion
  26. 26. The current results • The mental model seems to be common as own emotional transition. • The correlation between own emotional transition and mental model remains meaningful with controlling static structure using some dimensional evaluations.
  27. 27. Limitation • Participants in this study did not make predictions in a naturalistic context.
  28. 28. Conclusion • We used mental model for other persons based on our emotional transitions. That is, our emotion predicted others’ emotion!
