Definitions:

Intervention

Strategies or actions taken to improve a situation or problem, often used in the context of behavioral or medical treatment.

Behavior Change

A modification in an individual's behavior patterns, attitudes, or actions.

Multiple Baseline Design

A method of graphing behavioral observations that provides a way to evaluate the effectiveness of an intervention when a reversal design is not desirable. A multiple baseline design permits recording and analyzing behavioral observations from three variables: (1) two or more behaviors associated with one student in a single setting, (2) two or more students exhibiting the same behavior in a single setting, and (3) two or more settings in which one student is exhibiting the same behavior.

Reversal Design

An experimental technique where a behavior is measured before and after a treatment is introduced, and then once again when the treatment is removed.
