I'm majoring in social work and minoring in psychology.
We are not taught exact phrases, but taught techniques to work on client's strengths - how to take the situation and toss it back to the client with a positive spin on things.
In social work we are taught to look at non-verbal communication cues of all kinds - and how to react to them.
It takes a lot of case studies, role playing, feedback sessions, case analysis of pretend clients/sessions, to learn how to react appropriately to whole range of situations that come up in a counseling session.
When doing a role play, and having 30 social worker students critiquing and the teacher doing the same, it helps mold you on what you did right, wrong, and what could have been better.
