Mari Martin spoke on Super Communicators, based on a book by the same name that she admires by Charles Duhigg.
Super communicators excel at reading the room. They smile and laugh more, make eye contact, actively listen, and ask lots of questions, talk so you can see their teeth, and mirror back keywords to their conversation partner/group (looping). They send a message of confidence, caring, and energy. They have a warm and rich tone to their voices and project enthusiasm through tone, pace change, and word emphasis.
We want to sync with others and often excel when we do. Group activities such as good conversations, group singing, sports, etc. help us sync with others.
