Through modelling you can replicate the desirable skill or behaviour of any one. What the person has acquired in a long period of time can be appropriated by you in a much shorter time and hence the whole process is accelerated learning.
Richard Bandler and John Grinder gives the pragmatic ways to replicate and produce the desirable skills or behavior. They modeled the strategies of Virginia Satir and duplicated her extraordinary results in family therapy. What Bandler and Grinder did differently was to find the thinking strategies she was using while copying behaviors. Many others like Anthony Robbins have adopted their techniques and modeled others successfully.
Merely copying one’s behavior may not be enough; one has to assimilate core beliefs, and thought process while matching his physiology, and the motor skills. You should know the person extremely well in the particular setting. Pick up the pattern of their behaviors at an unconscious level and 'tune in' your motor-skills to theirs or replicate his patterns of muscle movements, physical postures and gestures, and a number of other minute muscle movements without any rationalization and then you can have the same degree of skill or replicate his behavior in that setting.
Children model elders-they are natural modelers. They do not have any expectation or anxiety of the outcome or consequences of their modeling and they succeed at a phenomenal rate. They learn a language from the early developmental environment. In the school he/she is exposed to learning information through instruction. This is a new learning system and the child develops appropriate strategies. As he becomes an adult he has already ingrained certain learning methods. Modeling re-teaches a person how to learn effectively without the involvement of any conscious learning system.
In the case of a child, the learning of a set of skills and techniques is without any rationalization or any conscious intervention. The modellee simply models the person blindly to develop the necessary skills, behaviors, motor skills and unconscious processes that the other person has without trying to interpret what they do. You do not try to understand what you want to learn consciously but you simply try to mirror and match the person in his physiology, dressing and grooming, voice patterns, thoughts and the why of his behaviour and actions.
