Dialogue has an important effect on self-perceptions locus of control.
Effective interpersonal communication can improve the self-perceptions of those we talk to. Effective self-dialogue can improve perceptions about ourselves. In Chapter 4 of Raising Self-reliant Children, Glenn and Nelsen discuss five conversation modes that act as barriers to the receptor's perception of personal capability. For each barrier, they suggest an alternative dialogue technique that tends to build the other person's self-confidence and internal locus of control. Use personal examples, where appropriate, to reinforce your point of view.
