This movie was clever. I liked the double helix staircase, the islands and the long term memory idea. What was interesting was that Riley's mothers emotion characters was led by Sadness and the Dad, anger. Riley's was Joy obviously.
Wrote about some of the characters on my blog a few days ago.
Joy: ESFJ
Extroversion - Highly focused on the outside world
Fe - external harmony, encouraging others, expresses happiness, radiates emotions all the time
Si - becomes stressed when the situation go wrong, wants to restore this back to normal, afraid of unfamiliarity, aware of how negativity affects well being and health.
Disgust: INFP...why not?
Introversion - Impressions are filtered subjectively
Fi - feels repulsion and dislike towards the actions of people, strong sense of her own ideals
Ne - perceives what an object could potentially do in a situation
Si - awareness of internal sensations affect Riley's physical state
Fear - Si dom
Introversion - subjective impression of reality
Si - for same reasons as Disgust, except more aware of how it affects himself
Anger - Se dom
Extroversion - Sees the outer world and subjects as actually is
Se - Asserts himself strongly, reacts to surroundings
I don't think Sadness can be typed, but it is fair to point out that sensing is weak as she engages little with any activity. An introvert and a feeler is likely.
