Shaping

A technique in training where closer and closer matches to the aimed behavior receive reinforcement.

Extinction

Within the realm of psychology, this refers to the slow diminishment and ultimate vanishing of a learned reaction when the previously associated stimulus is no longer linked with the natural stimulus.

Generalization
