About the reinforcement, it includes primary reinforcement or secondary reinforcement. Primary reinforcement is the directly biological one to fulfill the basic needs of organism, for example, food and water. Secondary reinforcement is the artificial and arbitrary one, for example, prestige.

For the schedules of reinforcement, there are continuous reinforcement and partial reinforcement. Continuous reinforcement means that the reinforcement will be presented every day and plays a limited role in our lives, for example, a breakfast prepared by mother. Partial reinforcement means that the reinforcement will be presented only in a particular time in a day, for example, a bell ring in school.

Besides, some are called ratio schedules and interval schedules. They can be fixed or variable. Fixed-ratio schedule means the number of responses that has to be made is fixed at a particular value. For example, every time I go to school, my teacher will give me a pencil.

Variable-ratio schedule means the organism is still reinforced only after making a certain number of responses, but that number varies unpredictably. For example, the gambling on Mark Six.

Fixed-interval schedule means the organism is reinforced for its first response after a certain time interval has elapsed. For example, the monthly salary pays to the workers.

Variable-interval schedule means reinforcement still depends on a certain interval having elapsed. For example, going to fish.
