Increasing self-efficacy - The Pygmalion effect

Increasing self-efficacy.

The best way for a manager to use verbal persuasion is through the Pygmalion effect or the Galatea effect.
The Pygmalion effect is a form of self-fulfilling prophecy in which believing something can make it true. The Pygmalion effect increases self-efficacy when we communicate to an individual's teacher or supervisor that the person is of high ability.
The Galatea effect occurs when high performance expectations are communicated directly to an employee. Sailors who were told convincingly that they would not get seasick in fact were much less likely to.
