“Selfee”, that is take a photo by myself has at least three psychological benefit for communication.
1. Mirroring/Matching tequnique
Working together for picture
Working together with their body movement, breeze etc. same.
3. cognitive dissonance
Once taking a friendly picture, people starts thinking good relation leads this photo.
Talking with open hart is very important for communication.
There are a lot of techniques to be open hart in NLP(Neuro Linguistic Programing). One of them is “Mirroring Technique” that is, behave like a scene of mirror of the person you are talking, like move same gesture.
But this is a little difficult because the person easily notice that you are using Mirroring.
I recommend to mirror just the leanness of the pasture of the person you are facing. Thats very effective!
