Multiple treatment interference
In an experimental design that requires the implementation of more than one independent variable to one subject, the outcome of one treatment may be influenced by the effect of another.
D. Experimental Design
Multiplicative effects
When the effects of one component of a treatment package may be influenced or modified by the presence or interaction of another component.
NCR reversal technique
A variation of the reversal design in which noncontingent reinforcement is used as the control condition and contrasted against contingent reinforcement. Responding is reversed to a level obtained in a
Nonconcurrent multiple baseline across participants design
A variation of the delayed multiple baseline design in which the baselines are so delayed that there is no overlap between them, like a series of AB designs across participants.

Nonparametric analysis
A type of experiment in which the effects of the independent variable are presented and withdrawn, comparing the effects of both conditions on the dependent variable
Parametric analysis
A type of experiment in which the effects of differential amounts of the independent variable are presented and compared to the dependent variable.
Practice effects
Refers to an improvement in responding from the opportunity to practice a behavior, specifically during prolonged baseline measurement periods.

Repeated reversals design
A variation of the reversal design that includes replication, in which responding is reversed to a level obtained in a previous condition by alternating between specific independent variables and baseline
Replication (in baseline logic)
Demonstrating that reintroducing the independent variable after it was withdrawn produces a return of the dependent variable to levels similar to those observed in previous independent variable Hint: This is

Reversal design
Any experimental design in which responding is reversed to a level obtained in a previous condition by alternating between specific independent variables and baseline conditions.
