What is Applied Behavior Analysis?

Applied behavior analysis is a science focused on understanding and improving socially important human behaviors. It is a practice that uses research-based interventions to improve targeted behaviors and use scientific methods to demonstrate the success of selected interventions. While our work is deeply rooted in the principles of behaviorism, the field is always evolving, growing and improving.


The Dimensions of Our Science

Applied behavior analysis is rooted in 7 dimensions (click the arrow to learn more)
  • Applied – A behaviour change is applied when it enhances and improves the everyday life of a learner, and those who are closest to a learner (e.g., parents, siblings, peers), by improving a socially significant behaviour.
  • Behavioural – The behaviour chosen must also be observable and measurable. By defining a behaviour that makes it easily observable and measurable, we are able to study it for proof of improvement, as well as lack of improvement. By defining a behaviour, practitioners are able to collect data and show change over time.
  • Conceptually Systematic – Interventions are consistent with the principles demonstrated in the literature and the research. It is important that practitioners continue to use research-based techniques, and avoid using any shortcuts in our teaching methods.
  • Technological – Procedures are described clearly and concisely so that others may implement the procedures accurately. Think of this dimension like a recipe – all steps are written in detail to get the desired result. You would not be able to follow a recipe if it did not list the specific ingredients and measurements. Same thing goes for Applied Behaviour Analytic interventions!
  • Analytic – Using data to make informed decisions. The practitioner is able to show that whenever he/she applies a certain variable, the behaviour is produced, and whenever he/she removes this variable, the behaviour is lost (Baer, Wolf, Risley, 1968).
  • Effective – Iinterventions are effective when they improve a behaviour in a practical matter. If the application of behaviour techniques does not produce large enough effects for practical value, then the application has failed (Baer, Wolf, Risley, 1968). An intervention is effective when it changes the behaviour it seeks to change.
  • Generality – A behavioural change may be said to have generality if it proves durable over time, if it appears in a wide variety of possible environments, and/or if it spreads to a wide variety of related behaviours (Baer, Wolf, Risley, 1968). In other words, a behaviour demonstrates generality when the taught behaviour carries over into other contexts than just the training environment. We want these taught behaviours to be used in multiple settings, across multiple people, and to continue to be used in the future.

Applications of Behaviour Analysis

As varied as is human behaviour, the study and application of behaviour analysis has many applications.

Autism

Applied Behaviour Analysis (ABA) is best known for its application supporting Autistic children and adults . ABA focuses on improving socially significant behaviours and decreasing challenging behaviours that may be getting in the way.

Within sessions, a therapist implements an individualized treatment plan developed by a behavior analyst. The therapist encourages and assists the learning and development of skills through meaningful activities whilst creating a positive, fun, and reinforcing environment. Science-based techniques used include pairing, prompting, shaping, differential reinforcement, and task analysis.

Beyond Autism

Behaviour analysis is not only for autism. The behavioural analytic interventions can be utilised to support the development of many skills and the improvement of many behaviors across children, adolescents, adults and the elderly. Behaviour analysis is also utilised in other settings including education and businesses

Organizational Behaviour Management

Organizational behaviour management (OBM) is when the scientific principles of behaviour analysis are applied to organizations and their employees. Applications of OBM include performance management, learning and development, supervision and management, behavioral systems analysis and behavior based safety. OBM is used widely in healthcare, sports, and manufacturing, and is increasingly being taken into consideration in all types of human resource management systems.

Education

Behaviour analysis has been widely effective in schools. Interventions can be applied in a one-to-one setting or in group settings. Teachers have used behaviour analysis to better manage their classrooms, adapt their teaching and increase independence and academic performance.

Natural Environment Teaching

Natural environment teaching is an instructional method that involves learning in the person’s encounters everyday life. Skills are taught through naturally occurring routines such as play or everyday activities. One of the key principles of NET is to use the person’s interests or things that are highly motivating and engaging to them to facilitate learning and increase the likelihood that they will generalize more readily outside of therapy.

Discrete Trial Teaching

Discrete Trial Teaching (DTT) is a method of teaching in which behaviour therapist uses adult-directed, massed trial instruction, and clear contingencies to teach new skills. It is a structured ABA technique that breaks down skills into small, “discrete” components and systematically the therapist teaches these components one by one. During a DTT session, a tangible reinforcement that is motivating to the child is used for the desired response. This might include a toy or a preferred activity.

Verbal Behaviour

Verbal Behaviour is an approach based on the principles of Applied Behaviour Analysis used specifically to teach children with autism to learn communication and language by connecting words with their functions. In Verbal Behaviour, language is classified into different types or ‘operants’ based on their function, to name a few: mand (a request), tact (a label/comment), intraverbal (a response to a comment or a question), echoic (a repeated word).

Precision Teaching

Precision teaching is a precise and systematic method of evaluating instructional tactics and curricula. . It comes from a very strong quantitative scientific basis and was pioneered by Ogden Lindsley in the 1960s based largely on Skinner’s operant conditioning.

Early Start Denver Model

The Early Start Denver Model (ESDM) is an evidence-based naturalistic developmental behavioural intervention specifically developed for young children with autism or for those at risk for autism. It is a play-based intervention that fuses behavioral and developmental principles and aims to close the developmental gap that is becoming evident by targeting all developmental areas. ESDM therapy can be provided in group or one-on-one and can be implemented in different settings such as the home, clinic, or the daycare/ preschool.In ESDM, parents and therapists use play, joint activities, and everyday routines to build positive and fun relationships with the child. The child is encouraged to participate in meaningful interactions and communications that help to nurture their language, social, and cognitive skills.

Pivotal Response Treatment

Pivotal Response Treatment is a naturalistic intervention that relies on naturally occurring teaching opportunities and aims at increasing learner’s motivation by adding components such as turn-taking, reinforcing attempts, child-choice, and interspersing maintenance/pre-learned tasks. The four central areas that have been identified in PRT are (a) motivation, (b) learner self-initiations, (c) self-management, and (d) responsiveness to multiple cues. It is believed that when these areas are promoted, they produce improvements in targeted behaviours and many other areas in development. The ESDM model has a strong emphasis on Pivotal Response Training.

Self-Management Skills

Self-management is a behavioural strategy to increase independence and teach new skills through monitoring, recording, and rewarding a child’s own behaviour. Self-management strategies have been widely researched and are effective ways to teach independence of skills such as play, social, adaptive, language, communication, vocational, and self-regulation skills to individuals with autism.

Components of self-management include identifying a goal, modifying the environment to increase the likelihood that the goal can be achieved, recording and monitoring own behaviour to determine whether or not the child is progressing towards the goal, and implementing reinforcement to oneself when the goals are met.

Self-management is a useful intervention for individuals of any age and can be used to generalize behaviours and skills across environments and settings, including school, home, and the community.
