Pygmalion effect

Pygmalion effect refers to the phenomenon in which the greater the expectation placed upon people, often children or students and employees, the better they perform. The Pygmalion effect is a form of self-fulfilling prophecy, it is a prediction that causes itself to become true. In this respect, people with poor expectations internalize their negative label, and those with positive labels succeed accordingly. For example, you assume you are going to perform badly at your test today so you decrease the effort and end up doing poorly. If I think my relationship with my significant other is going to fail, I start acting differently, pulling away emotionally, which may cause it to fail.
