Many people have negative connotations about using reinforcement with individuals with autism, but we know that for some people, this is necessary—just as our paychecks are necessary for most of us to continue working!  This presentation will begin by reviewing the concept of motivation, which will be discussed in terms of the contingencies in place for responding – in other words, what the "reasons" are for individuals to behave the way they do.  This discussion also involves the concepts of preference and reinforcement.  Preference can be thought of simply as what a person likes or enjoys, while reinforcement refers to providing a consequence for a behavior that increases or maintains the frequency of that behavior (e.g., your paycheck is the consequence that maintains your going to work behavior).  Although we all have things that we prefer, not all highly preferred items serve as reinforcers for all responses.  For example, you may prefer chocolate, but if your paycheck was replaced by chocolate, the chocolate would likely be insufficient to maintain your going to work behavior.  For all of us, reinforcement is crucial for maintaining behavior and learning new skills.  Unfortunately, it is often difficult to identify the most potent reinforcers for individuals with autism.   In general, the more potent a reinforcer is, the better the performance of the individual.  Thus, in order to maximize learning or work performance, it is important to identify and use an individual’s most potent reinforcers.

Most practitioners working with individuals with autism identify preferences by asking parents and caregiver what the individual prefers.  However, several studies have demonstrated that these methods are generally inaccurate.  Over the past 20 years, there has been a great deal of published literature on developing techniques to identify efficient and effective reinforcers for individuals with autism.  Research has demonstrated that conducting systematic preference assessments is the most effective way to identify potential reinforcers for individuals with autism.  The majority of this presentation will focus on describing the techniques that have been validated to accurately identify preferences.  The presentation also reviews practical issues related to assessing preferences, such as how often preferences may change, and how motivating operations may influence preference assessment outcomes.  Also, we will discuss how to empirically determine if an item truly functions as a reinforcer.  Finally, the importance of allowing choice for individuals with autism will be reviewed, and this presentation will provide information regarding several different ways that choice can be incorporated into the daily lives of individuals with autism.
