Reinforcement Schedule

In 1957, Ferster and Skinner devised various ways of delivering reinforcement and found
that they affect The Response Rate (the rate at which the rate pressed the lever) and The
Extinction Rate ( The rate at which lever pressing dies out). Below is the table showing the

types of reinforcement with respective description and example.
