Partial reinforcement

Partial reinforcement refers to a learning strategy where a behavior is reinforced only some of the time, rather than every time it occurs. This approach can make the behavior more resilient and resistant to extinction because the organism learns that reinforcement is unpredictable. For example, a slot machine pays out occasionally rather than every time, encouraging players to keep playing. In everyday life, it applies when rewards or praise are given irregularly, which can strengthen desired behaviors more effectively than consistent reinforcement. This principle is widely used in training, education, and behavioral therapies to establish lasting habits.
