Shaping
In Plain Language
Reinforcing gradual steps toward a new form of behavior.
ABA Definition
Differential reinforcement of successive approximations to a target response, with criteria changing as performance develops.
Everyday Example
A music teacher first recognizes a rough note, then increasingly accurate versions.
ABA Example
A learner is reinforced for progressively clearer versions of a chosen motor action.
How It May Be Used
Unlike chaining, shaping changes response form rather than connecting a sequence of steps.
