Question

Quizplus · Accepted Answer

Nonspecific treatment effects refer to changes in participants' behavior that are not specifically due to the treatment being administered, but rather due to all of their experiences in the research setting other than the treatment. This includes factors such as placebo effects, demand characteristics, and experimenter bias. Option A pertains to the specific effects of the independent variable, and option B refers to the effects of the dependent variable on the independent variable, both of which are not related to nonspecific treatment effects. Option C refers to volunteer bias, which is a separate issue from nonspecific treatment effects.
