There are three branches of science of behavior analysis [i.e., experimental analysis of behavior, behavior analysis, and applied behavior analysis (ABA)]. ABA can be defined as a systematic approach to understanding behavior of social interest. For the past 40 plus years, researchers have evaluated ABA and ABA based procedures (e.g., behavioral…

New, unsubstantiated therapies for individuals diagnosed with autism spectrum disorder (ASD) that lack empirical support for their effectiveness seem to be introduced almost daily. These unproven therapies should be subjected to the methods of applied behavior analysis to experimentally evaluate their effectiveness. This study provides an…

Abstract: Punishment is any stimulus change following a response that decreases the probability of that response occurring in similar situations in the future. Punishment-based techniques (i.e., techniques developed based upon the functional definition of punishment) are effective at decreasing undesired behavior. Despite the documented…

Errorless learning and error correction procedures are commonly used when teaching tact relations to individuals diagnosed with autism spectrum disorder (ASD). Research has demonstrated the effectiveness of both procedures, as well as compared them. The majority of these studies have been completed through the use of single-subject experimental…

One intervention that has been evaluated in numerous empirical investigations and has been implemented clinically is Social Stories. Social Stories are a systematic form of intervention where a text is written describing a situation (e.g., social situation) and how the learner should respond during that situation. Previous reviews and analysis…

Researchers have demonstrated that comprehensive behavioral intervention can result in significant improvements in the lives of individuals diagnosed with autism spectrum disorder (ASD; e.g.; Lovaas, "Journal of Consulting and Clinical Psychology" 55(1):3-9, 1987; McEachin et al., "American Journal of Mental Retardation"…

There has been rapid growth in the number of behavior analysts and interventionists in the world today. With this growth it is imperative to ensure that each behavior analyst and interventionist receives quality training. The training should be comprehensive (i.e. training multiple areas of behavior analysis) and should not conclude until the…

In this study we evaluated a social skills group which employed a progressive applied behavior analysis model for individuals diagnosed with autism spectrum disorder. A randomized control trial was utilized; eight participants were randomly assigned to a treatment group and seven participants were randomly assigned to a waitlist control group. The…

Individuals with autism spectrum disorder (ASD) have qualitative impairments in social interaction and often prefer food or tangible reinforcement to social reinforcement. Thus, therapists who work with children with ASD often use food or tangible items as reinforcers to increase appropriate behaviors or decrease problem behaviors. The goal of the…

The provision of reinforcement to increase desired behaviors is a crucial element of behavior analytic intervention for individuals diagnosed with autism spectrum disorder (ASD). Formal preference assessments, like the multiple stimulus without replacement procedure (MSWO), are often used to determine reinforcers used during intervention. While…

Today, the use of formal preference assessments, including paired-stimulus preference assessments, is widely utilized to help determine which items to use as reinforcers during intervention. A second way to determine potential reinforcers is to analyze multiple dimensions of a stimulus in the moment, a procedure known as in-the-moment reinforcer…

Today many special education classrooms implement procedures based upon the principles of Applied Behavior Analysis (ABA) to establish educationally relevant skills and decrease aberrant behaviors. However, it is difficult for school staff and consultants to evaluate the implementation of various components of ABA and general classroom set up. In…

One of the basic principles of applied behavior analysis is that behavior change is largely due to that behavior being reinforced. Therefore the use of positive reinforcement is a key component of most behavioral programs for individuals diagnosed with autism. In this study we compared four different classes of reinforcers (i.e., food, praise,…

Background: Children with autism spectrum disorder have impairments in social behaviours that require systematic intervention. The purpose of this study was to evaluate the cool versus not cool procedure implemented in a small group (dyad). Method: The cool versus not cool procedure consisted of the researcher demonstrating the targeted behaviour…

In Hong Kong, today's students diagnosed with an Autism Spectrum Disorder (ASD) receive their educational intervention through the public school system. This paper describes an application of a behaviorally based model to the only privately funded autism school in Hong Kong that serves up to 70 students diagnosed with ASD. General information…
