This cluster shows how people and animals act the same way when things look almost alike. It tells us why a child may say “dog” to every furry animal after learning the word with one picture. BCBAs use these rules to teach skills that last in new places, like using the toilet at school after learning at home. The studies help us plan training so good behaviors spread and problem behaviors don’t come back.
Common questions from BCBAs and RBTs
Stimulus generalization means a behavior trained with one stimulus also occurs with new, similar stimuli. It matters because skills learned in therapy need to work in the home, school, and community without retraining in every setting.
Build generalization in from the start by using multiple exemplars, varying settings and trainers, and reinforcing correct responding in new contexts. Do not wait until after mastery to think about transfer.
This usually means training stimuli were too narrow or included an irrelevant feature that the client learned to respond to. Vary your exemplars and check whether your materials share irrelevant features that may be controlling behavior.
Yes. Research shows that describing stimuli with words—such as calling a category of items dangerous—can shift how a person responds to new items in that category even without any direct behavioral training.
Peak shift is when responding after discrimination training is strongest at a point slightly beyond the training stimulus rather than at the exact stimulus used in training. It can affect real-world judgments and preferences in clinically meaningful ways.
