The double-blind procedure is a research method that helps distinguish between the direct effects of a treatment and those resulting from participants' expectations of the treatment. In this method, neither the researcher nor the participant knows whether they are receiving the treatment or a placebo, which helps eliminate bias and expectancy effects. Therefore, Dr. Volz is most likely to use the double-blind procedure in order to control for any placebo effects that may arise when testing the new antianxiety medication. The other choices (neurogenesis, rTMS, ECT) are not relevant to the research question at hand.
