These types of behaviors don’t just result in isolated improvements; they lead to widespread positive effects in other areas of the individual’s life.
Let’s break down the differences between these two concepts and explore why they matter for creating impactful interventions.
What Are Behavior Cusps?
Behavior cusps are behaviors that create access to new environments, opportunities, and experiences that were previously unavailable to the learner. When a behavior cusp occurs, it opens up new worlds of possibility, expanding the individual’s interactions with their environment in significant ways.
Example:
Teaching a non-verbal child with autism to use a communication device is a behavior cusp. This skill opens the door for the child to express their needs, communicate with others, and participate more fully in social interactions. This new ability transforms the child’s experience and access to new opportunities, such as forming relationships, making choices, and being more independent.
What Are Pivotal Behaviors?
Pivotal behaviors are behaviors that, once learned, trigger changes in other untrained behaviors. Unlike behavior cusps, which focus on opening up new environments or experiences, pivotal behaviors have a more internal effect, resulting in broad improvements across multiple behaviors without specific training for each one.
Example:
Teaching a child with autism to initiate social interactions is a pivotal behaviorPivotal Behavior is a type of behavior that, once acquire.... By learning to initiate communication, the child will likely see improvements in other areas of social functioning, such as maintaining conversations, responding to social cues, and engaging in more complex social interactions. This one skill has a ripple effect on their overall social development.
Behavior Cusps vs. Pivotal Behaviors: What’s the Difference?
While both behavior cusps and pivotal behaviors have far-reaching effects, the key difference lies in their impact:
- Behavior Cusps: These behaviors open the door to new contingencies, environments, or opportunities that the individual previously did not have access to. A behavior cusp introduces the learner to new experiences that can shape their future learning and interactions.
- Pivotal Behaviors: These are behaviors that, once acquired, lead to improvements in other behaviors that haven’t been specifically targeted for intervention. A pivotal behavior leads to changes across a broad range of areas, without the need for additional teaching.
Examples of Behavior Cusps and Pivotal Behaviors
To better illustrate the difference between these two concepts, let’s look at some practical examples:
Example 1: Communication Device (Behavior Cusp)
A child with autism is taught to use a communication device to express their needs. This skill allows the child to engage in more meaningful communication with others, ask for what they need, and participate in social interactions they previously couldn’t access. This is a behavior cusp because it opens the door to new opportunities and experiences that fundamentally change the child’s world.
Example 2: Social Interaction (Pivotal Behavior)
A child is taught to initiate social interactions, such as saying “hello” to a peer. This skill is a pivotal behavior because it leads to broader improvements in social skills, such as engaging in conversations, making friends, and responding to others in social situations. It has a significant impact on the child’s overall social behavior.
Example 3: Brushing Teeth (Pivotal Behavior)
Teaching a child to brush their teeth may be considered a pivotal behavior. By mastering this skill, the child’s oral hygiene improves, which positively impacts their overall health and well-being. This behavior doesn’t necessarily open new environments, but it leads to positive changes in related areas.
Example 4: Conversation Initiation (Behavior Cusp)
On the other hand, teaching a child to initiate conversations with others would be considered a behavior cusp. By learning this skill, the child gains access to new social opportunities, makes friends, and can participate in conversations they were previously excluded from.
Why Are These Concepts Important?
Understanding the difference between behavior cusps and pivotal behaviors helps behavior analysts design interventions that maximize learning opportunities and positive change. By focusing on teaching behaviors that either open doors to new experiences (cusps) or lead to widespread improvements in other behaviors (pivotal), practitioners can create more effectiveEffective refers to one of the seven dimensions of Applied... and efficient behavior change programs.
Final Thoughts
Both behavior cusps and pivotal behaviors are essential tools for promoting meaningful behavior change in ABA. While cusps open up new opportunities and environments, pivotal behaviors lead to widespread changes across multiple areas of a learner’s life. By identifying and targeting these behaviors, behavior analysts can help learners unlock their full potential, leading to more comprehensive and lasting improvements in their lives.
