Response Dimensions and Response Classes

Response Dimensions

• Response dimensions are ways to measure different aspects of a behavior.

Topography

• Topography refers to what a movement or behavior looks like.

  • Example: Clicking a pen involves pressing down until a click is heard and then releasing.

  • The same topography can have different functions depending on the context.

    • Example: Pressing a remote button may have the same topography as clicking a pen, but it serves a different function.

Latency

• Latency is the time elapsed between a direction or cue and the onset of the behavior.

  • Example: The time between a traffic light turning green and moving your foot to the gas pedal.

Duration

• Duration is how long a behavior lasts.

  • Example: The length of a video.

Other Dimensions

• Force or Intensity

• Magnitude

• Pitch (for sounds)

• Volume

• Impact on the environment

Importance of Quantifiable Elements

• Describing behaviors with quantifiable elements allows for clear communication and replication.

• Essential for the technological aspect of ABA, ensuring interventions can be replicated by trained individuals.

Dimensions in Intervention

• When designing an intervention, it's important to decide which dimensions to include in the description of the behavior.

• Examples:

  • Duration: How long a behavior lasts. Displayed at the bottom of the video.

  • Latency: Time from signal to response. E.g., time from phone ringing to answering.

  • Topography: The form of the behavior, including location, movements, and body position.

    • Useful in sports coaching.

Response Class

• A response class includes responses that share a dimension, a function, or their effects on the environment.

• Behaviors that do the same thing, have the same results, or share a temporal quality.

• Same topography can have different functions.

Example: Spraying a Bottle

• Spraying a bottle can have the same topography but different functions:

  • Punishing a cat. Cleaning a monitor. Watering a plant.

• Important when considering challenging behaviors.

Challenging Behavior

• An individual can engage in the same response (e.g., hitting) in different contexts for different functions.

  • Hitting a sibling to access a toy.

  • Hitting in a work setting to escape work.

  • A high five as a social greeting.

Importance of Context

• Just because a behavior looks the same does not mean it always has the same function.

• Need clear descriptions of the dimensions and context of the behavior.

• Aids in consistent intervention and functionally appropriate replacement behaviors.

Defining Response Classes

• Response classes can be defined in terms of:

  • Dimensions: Where or how long someone engages in a behavior.

  • Function: The outcome the behavior produces on the environment (reinforcing or punishing).

  • Effects: Susceptibility to reinforcement or punishment.

Differential Reinforcement

• Differential reinforcement involves reinforcing response classes.

• Behaviors with the same function or outcome.

• Access to the same reinforcer.

Example: Escape from Class

• Swearing at the teacher, throwing a pencil, and slamming a math book on the table all result in escape from class.

• These behaviors belong to the same response class.

Movement

• The same movement can belong to a response class, but it may not always have the same function.
