Final answer:
Asymmetric transfer in experimental design can be detected statistically. If this occurs, switching to a between-subjects design can help eliminate order effects.
Step-by-step explanation:
Asymmetric transfer occurs when the order of treatments in an experiment has an unequal effect on the outcomes. To detect this, statistical methods can be used. If the sequence effects are found to be asymmetric, researchers can switch to a between-subjects design, where each participant is only exposed to one treatment condition. This helps eliminate any potential order effects.
