Response Cost
In Plain Language
Losing a specified amount of a reinforcer following a behavior.
ABA Definition
A negative-punishment procedure involving contingent removal of a specified amount of an available reinforcer, evaluated by decreases in future responding.
Everyday Example
A late return fee removes money; if late returns decrease, the fee has a punishment effect.
ABA Example
A clinician may encounter a token-loss procedure in an existing plan and review its effects, risks, and alternatives.
How It May Be Used
Describes a procedure, not a home-use recommendation; loss does not establish an effect without data.
