They communicate by emotional contagion. Because emotionally immature people have little awareness of feelings and a limited vocabulary for emotional experiences they usually act out their emotional needs instead of talking about them. They use a method of communication known as emotional contagion, which gets other people to feel what they’re feeling. Emotional contagion is also how babies and little children communicate their needs. They cry and fuss until their caretakers figure out what’s wrong and fix it. Emotional contagion from an upset baby to a concerned adult is galvanizing, motivating a caretaker to do anything necessary to calm the child. Emotionally immature adults communicate feelings in this same primitive way. As parents, when they’re distressed they upset their children and everyone around them, typically with the result that others are willing to do anything to make them feel better. In this role reversal, the child catches the contagion of the parent’s distress and feels responsible for making the parent feel better. However, if the upset parent isn’t trying to understand his or her own feelings, nothing ever gets resolved. Instead, the upsetting feelings just get spread around to others, so that everyone reacts without understanding what is truly the matter.
