A rat is being trained to learn its way through a complex maze. When the rat successfully makes its way through the maze, it receives water and food and runs faster next time. What psychological principle does this example illustrate?

A. stimulus
B. reinforcement
C. introspection
D. cognition

The answer is B. reinforcement.

Reinforcement is a type of motivation that occurs through rewards (positive reinforcement) or removal of unpleasant stimulus (negative reinforcement). In the example, the rat is motivated through positive reinforcement.
