There are several different research designs that are used frequently in Applied Behavior Analysis. These different research designs are very helpful to the behavior analyst in several ways. Behavior analysts look at the behavior that is to be changed, but more so, they look at the close relationship between the stimuli and the behavior that is being changed, as well as the individual whose behavior is being changed (Richards, Taylor, Ramassamy, & Richards, 1999). These methods help the behavior analyst determine whether a particular behavior plan is working well for that individual or whether it needs to be modified. Since the analysts wish to encourage “valuable behaviour,” the behavior that is being targeted will be one that will continue to be reinforced and maintained even after the experimental conditions of the design are withdrawn (Richards, et al, 1999). One such design is the changing criterion design. This design looks at and evaluates the effects of a treatment on the gradual and systematic increase/decrease of a single target behavior (Richards, et al, 1999). This is done by changing the levels necessary to meet contingencies to increase or decrease a behavior. So, the intervention is shown to be effective when the target behavior changes to the predetermined criterion level. There is a baseline phase where baseline data of the behavior to be changed is collected. Then the intervention/treatment phase is divided into subphases, each with its own criterion
The visual representation above displays an intervention procedure used to decrease Tommy's throwing behavior by implementing extinction and differential reinforcement of alternative behavior (DRA). Baseline data was recorded for five consecutive days before the intervention phase was implemented. The baseline data shows a high level in frequency of throwing behavior. Once baseline was stable, the intervention phase was implemented and recorded for ten consecutive days. Extinction and DRA were implemented as part of the intervention procedure. The data path during intervention displayed a decreasing trend with low variability. The use of a A-B design can have a disadvantage as it does not establish a functional relation that confirms
Development of an intervention is the final step in the functional behavior assessment (FBA) process. In the completion of the FBA antecedent and reinforcing contingencies are identified which can be manipulated to prevent the behavior from occurring, remove reinforcement for engaging in the undesired behavior, or be utilized to reinforce alternate behaviors (Cooper, Heron, & Heward, 2007). An FBA is a necessary component of the intervention process in that it provides the necessary information with regard to the function of the behavior through the systematic manipulation of environmental variables thought to maintain the problem under controlled conditions; yielding a clear demonstration of the interaction between the independent variable

Positive behaviour support (PBS) is an approach to providing services to individuals who exhibit challenging behaviour. Since the early 1990s, PBS has received increasing attention from the behaviour-analytic community. Some behaviour analysts have embraced this approach, but others have voiced questions and concerns. Over the past dozen years, an approach to delivery of behavioral services known as positive behavior support has emerged as a highly visible movement. Although PBS has been substantially influenced by applied behavior analysis, other factors are also part of its
Punishment-Based interventions are types of treatment that is sometime used in the field of Applied Behavior Analysis to modify or change behaviors. There is a quite a bit of controversy and misunderstanding related to use of punishment. Punishment-based interventions have been proven to be one of the most controversial treatments used by behavior analyst and found in behavior analyst literature (e.g. Johnston, 1991; Matson & Kazdin, 1981; Repp & Singh, 1990) (DiGennaro Reed, & Lovett, 2008). The definition itself is many times confused or lack understanding. Cooper, Heron, and Heward (2006) explain that punishment frequently misunderstood, misapplied and quite controversial. There are some therapists or behavior analysts, parents, caregivers, teachers, and people in general who support punishment and some who do not (Hall, 2013). Although there is a lot of controversy about whether to use punishment or not, punishment is indeed still sometimes used in the field of applied behavior analysis, but there are special guidelines for using punishment based procedures in the field. Before a behavior analyst can decide whether or not they want to use punishment in an intervention, they must clearly understand the definition
According to behaviorist principles, adults can increase their capacity for modifying the behavior of children by:
The publication “An Implicit Technology of Generalization” shined a spot light on generalization as an active process that needs to be studied by behavior analyst in order to help validate behavior programs. The study exhibits not only the immediate effects of our procedures but the lasting change that could be achieved in multiple environments of a client’s life. It has been concluded that generalization should be programed for and not just expected to happen. Stokes and baer (1977) described generalization as” the occurrence of relevant behavior under different, non-training conditions (i.e., across subjects, settings, people, behaviors, and/or time) without the scheduling of the same events in those conditions as had been scheduled in
Applied Behavior Analysis analysts are required to know the steps that are needed and necessary for behavior modification. This type of modification requires a clear definition of the behavior needing modification (target behavior), how this will benefit the individual in need of the modification, a clear plan of modification, and consistent data gathering to determine the effectiveness of the proposed behavior modification plan. In order to achieve a successful modification plan, the ABA professional first needs to gather information about the individual either by direct or indirect means. The modification must always been in the best interest of the individual, or those closest to the individual, and it must be a functional modification that can be carried out in the absence of the analyst. The ABA professional needs to understand the needs of each client. In order to do this, the professional will have to assess the behavior, gather data, identify a target behavior, propose a hypothesis about an intervention, implement the modification program, gather more data about the effectiveness of the program, and report about the outcome.
A career action plan in applied behavior analysis will be important in speculating the kind of career to undertake once through with the studies. It can be an excellent tool for a student to develop to ensure swift absorption in the job market or to those wishing to start their own organizations (Cooper, 2007).
Applied Behavioral Analysis is a natural science that aims to systematically apply intervention processes using the behavior learning theory in order to remove or change undesirable socially significant behaviors (Cooper, Heron, Heward, 2007). Applied behavioral analysis can be applied in many setting and situations and the intervention process and techniques depend on those settings and individual situations. Applied behavioral analysis is used to modify target behaviors that can occur in
Applied Behavior Analysis (ABA) is one of the most misunderstood methods of reinforcement. ABA also is referred to as ‘behavior modification’, which is the main contributor of the negative connotation with this method. ABA is the application of behavioral learning principles to change behavior (Woolfolk 256). Applied Behavior Analysis can be very successful in the classroom if done correctly. However, to begin this, one must study a student to decide what reinforcers will best work to modify the behavior.
The third major development in the evolution of behavior modification was the publication in 1953 of B. F. Skinner's Science and Human Behavior. This work heralded a philosophical shift from the search for inner causes of behavior to an emphasis on the measurement and modification of observable behavior.
Behavior analysts should be aware of the values their clients’ have. The behavior analyst should be clear about the methods to be used and the underlying conceptual basis for the procedures when explaining them to the client or clients. This clear explanation may prevent conflicts from arising.
In applied behavior analysis behaviorists use techniques such as functional behavior assessment (FBA), to create functionally-based interventions that target maladaptive behavior. The goal of an FBA is to identify the conditions that predict behavior and the consequences that maintain behavior (Carr et al., 2002). If the link between antecedent, behavior, and consequence can be established, it will be possible to alter a behavior by changing its predictive stimuli and maintaining consequences (Bender, 2015). After forming this link by collecting data, a behavior intervention plan (BIP) will be created to diminish problem behavior (Bender, 2015). This BIP must target the function of the behavior and
Behaviorism has been credited with providing clear predictions that can be scientifically tested and yield explanations that can be supported by evidence. For instance, in the application of Applied Behavioral Analysis in improving clients’ behaviors, the functions of individuals problematic behaviors can be evaluated and modified using behavior change principles including reinforcement. Similarly, behaviorism emphasizes the objective measurement of behaviors through providing clear and conceptual definitions, and its therapy is applicable to real life situations as in the case of anxiety. Conversely, studies incorporated into behaviorism allow for appropriate comparisons between animals and humans as in the Case of Watson’s, Thorndike’s and Pavlov’s studies respectively.
