American, Carl Rogers (1902-1987) was the founder of this method of counselling and therapy and came from a Christian background. He researched the data in order to find out which type of therapy helped the client most. He discovered that all methods were beneficial if the counsellor portrayed three vital qualities - a non judgemental attitude, a genuine concern and had empathy for the client's problems. He did not attempt to diagnose or interpret the client, but gave patient support and considered responses to show that he understood what the client was saying on a deep and caring level. This a humanistic and existential method is often called 'Client Centred Therapy' and this caring response should be available to the client whatever method is being used. The object being to improve the client's life, so they are able to have better relationships, be able to work and enjoy their life and this state is called 'fully functioning'. From this 'student centred learning' or 'learner centred teaching' developed.
