Affective Realism

Did you know that if you are very tired, a hill actually looks steeper to your eyes? This is called affective realism. Your brain does not just see the world as it is; it sees the world through how your body feels. If you are cranky or hungry, a friend's joke might seem mean instead of funny. Your feelings are like a pair of colorful sunglasses that change the color of everything you look at. When you know this, you can stop and say maybe the hill is not that big, maybe I am just tired!

Your feelings are like sunglasses that change the color of everything you see. You are not seeing the world. You are seeing your body's opinion of the world. The brain is not a camera. The brain is a painter. It takes the raw data from your eyes and ears and then paints it with whatever color your body is currently feeling. Tired paints everything steep. Hungry paints everything hostile. Lonely paints everything cold. This is why two people can stand in the same room and see two different rooms. They are not disagreeing about reality. They are wearing different sunglasses. Take off the glasses. Check your body. Then look again.

Affective realism: internal bodily state directly influences sensory perception. The brain is predictive, using interoceptive data to construct external reality. The primary interoceptive cortex and primary visual cortex are deeply interconnected — mood is not a reaction to what you see but a filter determining what you see. Take off the glasses. Check your body. Then look again.

SOUND: A clock ticking — annoying when stressed, peaceful when calm: the same sound wearing two costumes.

SMELL: Your own house — a smell you only notice when you have been away: proof that perception is relative.

TASTE: Food tasting bland when you are sad: the tongue reporting the mood, not the meal.

TOUCH: A scratchy sweater feeling painful when you are overwhelmed: the skin amplifying what the heart is carrying.

SIGHT: A long hallway feeling impossible when you are sick: the eyes measuring with the body's ruler.

BODY: Feeling heavy like lead after a bad day: gravity increasing because the mood said so.

Music: Mr. Jones by Counting Crows

Music: Small World by Disney
