Definitions:

Alternating Treatments Design

An experimental design in behavior analysis that allows the comparison of two or more interventions by alternating them in a rapid succession to observe their effects on behavior.

Functional Relation

The relationship between a specific behavior and the environmental conditions that reliably influences the occurrence of this behavior.

Gradual Behavior Change

A slow and systematic modification of behavior patterns over time.

Multiple Baseline Design

An experimental design that introduces the intervention at different times across settings, behaviors, or subjects to demonstrate control over the variables being examined.
