Definitions:

Shaping

Shaping is a method of training by which successive approximations toward a desired behavior are reinforced.

Primary Reinforcement

A reinforcer that satisfies a basic biological need or desire, such as food, water, or sleep, which is inherently motivating.

Secondary Reinforcement

A type of reinforcement where a stimulus gains its reinforcing power through its association with a primary reinforcer.

Ratio Schedules
