What are the benefits/disadvantages of this schedule?
Chapter 4 defines positive and negative reinforcement and gives examples of each. You can think of the terms “positive” and “negative” in more of a mathematical sense than a “good or bad” sense. A positive reinforcer in a reinforcer that is applied (or added) while a negative reinforcer in a reinforcer that involves taking something aversive away (or subtracting). It is fairly intuitive to think of positive reinforcers such as giving a child a cookie for good behavior. Negative reinforcement is a bit more difficult. However, you simply have to picture a scenario in which something unpleasant is going on, you do something that successful ends that unpleasant stimulus, and you are now more likely to perform that behavior again because of the reward you experience. For example, many cars sound a nagging, dinging alarm when you sit in the driver’s seat without a seatbelt. In order to make this aversive stimulus stop, you put your seatbelt on. The removal of the dinging is reinforcing and you are now more likely to put your seatbelt on in the future. Escape and avoidance are also covered as two other types of negative reinforcement described in Chapter 4.
