How does the alternating treatments design differ from the changing conditions design?

A) The alternating treatments design is used to determine the effectiveness of more than   one intervention, while the changing conditions design is used to increase the standard   for acceptable performance.
B) Unlike the changing conditions design where interventions are introduced  consecutively, in the alternating  treatments design one intervention is rapidly substituted for another.
C) The alternating treatments design is a variation of the multiple baseline design, whereas t he changing conditions design is a variation of the reversal design.
D) Unlike the changing conditions design which is used to assess the effect of behaviors   over several settings, the alternating treatments design is used to assess the effect  several observers.

Alternating Treatments Design

A method for graphing behavioral observations that permits analysis of the differential effectiveness of more than one intervention on a target behavior. Unlike the changing conditions design, in which interventions are introduced consecutively, one intervention is rapidly substituted for another, sometimes on a session-to-session basis.

Changing Conditions Design

A method of graphing behavioral observations used to determine the effectiveness of two or more interventions to positively affect a target behavior. A refers to the baseline, B designates the intervention, and C designates the application of a second intervention. In a changing conditions design, different interventions are implemented consecutively without ever returning to baseline conditions. Sometimes called an ABC design.

Intervention

A strategic action or process aimed at altering a situation or condition, usually to improve it or prevent undesired outcomes.
