Introduction
Social mind
• People are remarkably good at understanding each other, and people can also predict others’ emotion and behavior.
Why ?
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.
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
Method
Cut it! (too complicatedPlease check the source article.
Simple Explanation 1
11:30, Happy 14:30, Relaxed
Look this transition!(Experience-sampled)
Simple Explanation 2
Look this transition!(Mental model)
Result
Study 1: N = 40, every 3h/d/2weeks
Study 1: Mental model
Study 1
Study 2: N = 40, every 3h/d/2weeks
Study 2: Mental model
Study 2
Study 3: N = 10,723, random timing
Study 3: Mental model
Study 3
There is the strong associations
NRMSE = normalized root mean square
error in simple regressions with ratings
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!
Particular valence is strong
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).
Study 5
• Almost results were replicated using the 2 million data from the Experience Project (www.experience project.com).
Discussion
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.
Limitation
• Participants in this study did not make predictions in a naturalistic context.
Conclusion
• We used mental model for other persons based on our emotional transitions.
That is, our emotion predicted others’ emotion!
