Interpersonal forms of power (authority) are the ways a Master molds his slave during training and manages her in the relationship. The interpersonal forms of power are:
Reward Power - ability to control the reward a slave wants; reinforcements. This is a positive and perhaps the more useful power.
Coercive Power - ability to cause a slave to have an unpleasant experience; punishment. A necessary power but not always the best.
Legitimate Power - based on position or mutual agreement. The slave agrees to accept her Master and grants him authority. This is why a contract is valuable in slave training because the contract grants her Master legitimate power, by establishing his authority in writing. In addition to setting goals, it allows both Master and slave to discuss the process and allows her to see and agree to the authority she is granting him.
Reverent Power - an elusive power that is based on interpersonal attraction. The slave identifies with the Master and the Master is individualistic and respected by the slave. This is the personal connection between the two.
Expert Power - specialized knowledge or skills the slave needs. Three conditions must exist; trust, knowledge must be relevant and useful, and perception as an expert by the slave.
