APPLIED BEHAVIORAL ANALYSIS
Definitions and Core Concepts of ABA
Characteristics of ABA
Technological:
The procedures for behavior change must be described clearly and in enough detail so that anyone can implement them.
Example:
Instead of saying "The teacher praised the student for hand raising," a more detailed description would be "Every time a question is posed to the class and Mary raised her hand, the teacher provided the praise statement, 'Mary, I like the way you are raising your hand to answer questions.'"
Applied:
Behavior change should be socially significant to the individual and their community.
Example:
Teaching a teenager with autism to use a cell phone to call home when lost contributes to their safety and increases independence.
Behavioral:
Focus on observable and measurable behaviors, rather than internal feelings or emotions.
Example of behavior: Raising a hand in class, giving compliments, or going out to eat.
Example of emotions: Sadness or anger are not generally the focus.
Analytic:
A functional relationship must be demonstrated between an environmental event and a change in behavior.
Example: The teacher must document that praise consistently leads to increased hand raising in a systematic manner.
Conceptually Systematic:
Procedures should be derived from a strong theoretical base.
Example: Praise leads to increased hand raising, grounded in core learning principles that state behavior increases when followed by a pleasurable consequence.
Effective:
The change in behavior must be large enough for others to observe.
Example: If praise leads to a substantial increase in hand raising (e.g., 10 occurrences per hour), it is noted as effective.
Generalizable:
Changes in behavior should be observed across various settings and maintained over time.
Example: A student who raises their hand in one class should do so in others and when returning from breaks.
Historical Background
Early 1900s
The field of psychology was dominated by introspection and internal mental processes.
1913:
James B. Watson proposed behaviorism, advocating for the objective study of observable behavior and how environmental factors influence it through direct observation and stimulus-response interactions.
Example: When a child sees a bottle of milk, they say "bottle."
1938:
B.F. Skinner, in his work "The Behavior of Organisms," criticized Watson's stimulus-response model.
Introduced the significance of consequences in influencing behavior.
Proposed examining the three-term contingency: antecedent, behavior, consequence.
Defined behavior learned through consequences as operant behavior.
Behavior analysts focus on operant behavior.
1950s to 1960s
Skinner's principles were applied in various behavioral settings, including autism therapy.
The study by Wolf, Risley, and Meese focused on using positive reinforcement to aid a child with autism in wearing glasses.
1968:
Journal of Applied Behavior Analysis established, outlining the definition of Applied Behavior Analysis (ABA).
Applications of ABA
Broad Uses: ABA is primarily recognized for addressing developmental and behavioral issues.
Widely utilized in special education.
Also applied in general education settings, medical procedures, sports psychology, and organizational behavior.
Core Differences in Behavior Types
1. Respondent Behavior
Defined as involuntary and reflexive,
Example: Sneezing when smelling pepper or involuntary leg movement in response to the knee reflex test.
2. Operant Behavior
Defined as learned behavior influenced by antecedent and consequent events.
Observable and measurable.
Examples:
Greeting a colleague in the hall, checking social media, texting.
Three-Term Contingency
Components:
Antecedent: What occurs before behavior (e.g., phone buzzing).
Behavior: The action taken (e.g., checking the phone).
Consequence: The result of the action (e.g., receiving a funny photo).
Illustrated through multiple examples, demonstrating how behaviors can be reinforced (e.g., increasing the chance of checking the phone again).
Functions of Behavior
Understanding the functions helps identify the reason behind behaviors:
Escape: Behavior to avoid an undesired task.
Attention: Seeking social interaction or responses from others.
Access to Tangibles: Seeking physical items or sensory experiences and reinforcement.
Automatic Reinforcement: Providing self-stimulation or comfort.
Reinforcement and Punishment
Reinforcement
Positive Reinforcement: Increases behavior by adding a pleasurable stimulus following the response.
Example: A child says "please" and gets a snack.
Negative Reinforcement: Increases behavior by removing an unpleasant stimulus following the response.
Example: Buckling up to stop the car beeping.
Punishment
Positive Punishment: Decreases behavior by adding an unpleasant stimulus.
Example: A child is reprimanded for not washing hands leading them to wash their hands next time.
Negative Punishment: Decreases behavior by removing a pleasurable stimulus.
Example: Getting a speeding ticket results in loss of money.
Key Concepts in ABA
Data Collection and Documentation
Data is crucial for monitoring the effectiveness of interventions and adjustments needed for success.
Confronting Myths about ABA
Myth 1: ABA only occurs at a desk.
Reality: ABA principles apply in all settings (home, community).
Myth 2: ABA is only rote learning.
Reality: ABA encourages generalization of skills in natural environments.
Final Thoughts
Understanding and applying ABA allows for developmental, behavioral, and educational transformation in notable, evidence-based ways.
Focus on socially significant behaviors leads to meaningful changes in learners' lives.
Keep an open mind regarding myths surrounding ABA as you engage in training and practice within real-world contexts.
