What is Stimulus Generalization?

Stimulus Generalization happens when a response that was reinforced in the presence of one stimulus occurs in the presence of DIFFERENT (but similar) stimuli.

Simple Formula: Same Behavior, Different Setting/Stimulus.

Examples

- You learn to say "Dog" when you see a Golden Retriever. You then say "Dog" when you see a Poodle. (Success!).
- You say "Daddy" to your dad. You then say "Daddy" to the mailman. (Over-generalization - Oops!).

Frequently Asked Questions About Stimulus Generalization

How do we promote it?

Train Loosely. Vary the room, the teacher, the time of day, and the instructions. Don't be a robot.

What is "Multiple Exemplar Training"?

Teaching with many examples. Don't just use one picture of a shoe. Use boots, sneakers, heels, sandals. This forces generalization.

Is it always good?

No. Over-generalization is bad (e.g., Calling every man "Daddy"). We fix that with Discrimination Training.
