Generalization and Maintenance in Applied Behavior Analysis

Generalization and Maintenance

Types of Generalization

  • Two types of generalization:
    • Stimulus or setting generalization
    • Response generalization
Stimulus Generalization
  • Definition: Extent to which a trained response is exhibited in untrained settings and in response to untrained stimuli.
  • In simpler terms: Demonstrating a learned skill in different situations other than the one in which the skill was taught.
  • Example:
    • A student learns to button his shirt when asked.
    • Generalization occurs when the student can:
      • Button pants and coats.
      • Fasten large and small buttons.
      • Do this in various situations (home, restroom, school).
  • Demonstration:
    • Teacher teaches the student to label various forms of "dog".
      • Picture of a dog
      • Toy dog
      • Puzzle piece of a dog
      • Seeing-eye dog.
      • Video of a dog
Response Generalization
  • Definition: Extent to which untrained responses that serve the same function as the originally trained response are emitted.
  • In simpler terms: Producing a response that has the same outcome as the response that was taught.
  • Example:
    • A student learns to complete 2+32 + 3 by counting on fingers.
    • Response generalization occurs when the student begins to count in her head instead.
    • Counting in her head serves the same function as counting on fingers.
  • Demonstration:
    • Teacher greets a student named Dennis in different ways.
      • "Say hello."
      • Student says "Hello"
      • Student says "Hey, Lynn"

Importance of Generalization

  • Skills are only functional if they occur within a range of different contexts.
  • Example: Teaching a student to greet teachers in school.
    • Without generalization, the student will only greet teachers in that specific context.
    • With generalization, the student will greet:
      • Children at the playground.
      • Parents when they pick him up.
      • Cashier in the grocery store.
  • Many situations require having multiple responses that serve the same function.
  • Example: A child taught to request a snack by saying, "Can I have a cookie, please?"
    • Without response generalization, the child can only ask for cookies in that specific way.
    • With response generalization, the student can:
      • "Can I have a hug, please?"
      • "I want to wear this red shirt today."
      • "Cookies are my favorite. Can I have one?"
  • Achieving stimulus, setting, and response generalization gives more functionality and value to a response, making it more meaningful to the student.
