CHAPTER 3GETTING A BEHAVIOR TO OCCUR MOREOFTEN WITH POSITIVE REINFORCEMENTAnswers to Study Questions on Main Text1. A baseline is a measure of behavior in the absence of a treatment program. For example, in Danny’s case, his cooperative and commanding behaviors were assessed before Danny’s mother was instructed to react to them differently than she had in the past. Other examples may be appropriate.2. Behavior (or instances of cooperative behavior).3. Time (or sessions, or sessions in 10-minute intervals).4. A positive reinforcer is an event which, when presented immediately following a behavior, causes the behavior to increase in frequency.5. This principle states that if, in a given situation, somebody does something that is immediately followed by a positive reinforcer, that person is more likely to do the same thing again when he or she next encounters a similar situation.6. Operant behaviors are those that operate on the environment to generate consequences, and are in turn influenced by those consequences. For example, if a person walks into a dark room and emits the behavior of turning on a light switch, then the consequence of the light going on increases the likelihood that flipping the light switch will occur in asimilar situation in the future. Flipping the light switch is therefore an operant behavior.7. They are both laws of nature.8. Students can describe any plausible example, such as the following:Situation: A student in class did not understand a part of a lecture of one of the authors.Response of student: Approached professor after class to request help.Immediate consequence: Professor smiled warmly, and said, “Of course! How can I help you?”Long-term effect: Student is more likely to approach professor (and perhaps other professors) for help in the future.CHAPTER 4DEVELOPING AND MAINTAINING BEHA VIORWITH CONDITIONED REINFORCEMENTAnswers to Study Questions on Main Text1. Unconditioned reinforcers are stimuli which are reinforcing without prior learning, or without having to be associated with any other reinforcers. Food for someone who has not eaten for several hours, or water for someone who has not had a drink for several hours, are unconditioned reinforcers. Other appropriate examples are acceptable.2. A conditioned reinforcer is a stimulus which was not originally reinforcing but which acquired reinforcing power through association with a stimulus that is reinforcing. For example, a piece of green paper that constitutes a dollar bill is not likely to be a reinforcer for an infant or a young child who has had no experience with money. However, after the dollar bill is paired with a variety of backup reinforcers while making various purchases in stores, the dollar bill becomes a powerful reinforcer. Any two appropriate examples are acceptable.3. A backup reinforcer is a reinforcer on which a conditioned reinforcer is based. In a token system it is a reinforcer for which tokens can be exchanged in order to maintain their reinforcing power. For example, at the end of a poker game, poker chips can be exchanged for money. In this case, the money is the backup reinforcer. Any two appropriate examples are acceptable.4. The backup reinforcers included time on Facebook or YouTube.5. Any appropriate example is acceptable.6. Tokens are conditioned reinforcers that can be accumulated and exchanged for other reinforcers.7. A token system is a behavior modification program that uses tokens to reinforce desirable behavior. The tokens can be exchanged for more powerful reinforcers called backup reinforcers.8. Yes, money is a token because it can be accumulated and exchanged for a variety of backup reinforcers (the things that money can buy).9. Examples might include two of the following: praise, a call to dinner, the sight of a lovedone, or a friendly greeting. These are all associated with more powerful reinforcers. 10. A conditioned punisher is a stimulus which is not originally punishing, but which acquires punishing power through association with a stimulus that is punishing. Examples might include criticism, scoldings, a failing grade, and the sight of a muggerin a dark alley. These are all typically punishers because they have been paired with other aversive events.11. A simple conditioned reinforcer is one that is paired with a single backup reinforcer. A generalized reinforcer is a conditioned reinforcer that is based on a number of different backup reinforcers. At any given time at least one of the backup reinforcers should be powerful enough to maintain the reinforcing effectiveness of the generalized reinforcer.12. Yes, praise is likely a generalized reinforcer for most of us. That is because when people praise us, they are disposed to favor us in a variety of ways so that praise ispaired with a variety of backup reinforcers. Also, positive adult attention (which might be considered a form of praise) is provided by parents when they feed their infants, wash them, play with them, and meet their needs in other ways.13. The points in Erin’s program were likely a genera lized reinforcer because they were paired with two backup reinforcers, time on Facebook and time on YouTube, both ofwhich provide a variety of conditioned reinforcers.14. The three factors influencing the effectiveness of conditioned reinforcers include:(a) the strength of backup reinforcers; (b) the variety of backup reinforcers; and (c) the number of pairings of the conditioned reinforcer with a backup reinforcer.15. If a conditioned reinforcer is presented a number of times without being associated with other reinforcers, it will eventually lose its reinforcing effectiveness.16. Pitfall Type 1 states that people who are unfamiliar with the principle of conditioned reinforcement may unknowingly misapply it in various ways. For example, if an adult scolds a child and then gives the child a treat because the adult “feels guilty,” the scolding may become a conditioned reinforcer. Pitfall Type 2 states that individuals who are not aware of the principle of conditioned reinforcement may cease to pair a conditioned reinforcer with a backup reinforcer causing the conditioned reinforcer to lose its effects. For example, a teacher who awards stars for good behavior, but fails to use effective backup reinforcers, will cause the stars to lose their value as conditioned reinforcers.Chapter 3: Getting a Behavior to Occur More Often withPositive ReinforcementMultiple Choice Questions on Main Text (Note: * indicates the correct answer)1. A positive reinforcer is defined as:a) an event which, when presented immediately following a behavior, causes the behavior to decrease in frequencyb) an event which is preferred by a subjectc) an event which the subject finds rewarding* d) an event which, when presented immediately following a behavior, causes the behavior to increase in frequency2. The principle of positive reinforcement states that:a) if, in a given situation, an individual is given a choice of two or more items, the item chosen will be the positive reinforcer* b) if, in a given situation, somebody does something that is immediately followed by a positive reinforcer, then that person is more likely to do the same thing againc) if, in a given situation, an individual is positively reinforced, then that individualwill select that situation in future opportunitiesd) a reinforcer can be used to strengthen behavior3. The best way to determine if something is reinforcing is to:a) ask the individual what they prefer for a reinforcerb) watch others perform the same behavior and find out what reinforces them and then use that with the individual of concern* c) conduct an experimental test in which you present an item following some behavior onseveral trials to see if the frequency of that behavior increasesd) provide a choice situation in which the “something” is presented along with known reinforcers to see if it will be chosen by the subject instead of the known reinforcers 4.
