It IS a fictional Pixar character…but they are showing us a picture of a healthy psyche. The characters in the movie are the family and the emotions inside their minds. Riley (11 y/o) is the heroine and the one who must balance and mediate her emotions. Notice she is not fighting fear or vanquishing anger.
In the clip there is mostly just the emotion feeling then pushing a button for the human character to act. But even seeing the visual panel of emotions implies that we have the ability to mediate our emotions before acting. Some of us suppress our emotions with reason by habit. I think this is very engrained in our collective cultural minds; this old disney movie from 1940 really shows this.
According to the June 2015 Atlantic article by Denis Smith, the director was aware of updating this emotional model. Do you see parts of yourself, your anger for example in either of these clips? What about desire? How about your partner?
