Stimulus generalization vs. discrimination
The difference in short
Stimulus generalization and discrimination are opposite stimulus-control processes. In generalization, behavior extends to stimuli similar to the trained one. In discrimination, behavior is restricted to a specific stimulus and doesn't occur with others.
Quick comparison
| Stimulus generalization | Stimulus discrimination | |
|---|---|---|
| Operation | Behavior extends to similar stimuli | Behavior is restricted to a specific stimulus |
| Effect | Same behavior, new stimuli | Responds to one, not others |
| Example | A child says “dog” to several different breeds. | Says “dog” only to dogs, not cats. |
How to tell them apart
- Does behavior EXTEND to new similar stimuli (generalization) or stay RESTRICTED to a specific one (discrimination)?
Examples
Stimulus generalization
A child says “dog” to several different breeds.
Stimulus discrimination
Says “dog” only to dogs, not cats.
Frequently asked
Are generalization and discrimination opposites?
They're two sides of stimulus control: one extends behavior to similar stimuli, the other limits it to a specific one. Both can be taught.
