Dr.Mentor is conducting an experiment examining the effects of cell phone conversations on reaction times while driving a car.Each participant,either conversing on a cell phone or not,manoeuvres a driving course on a simulator.This simulated drive is videotaped.The research assistant hired to do the coding of the video tapes does not believe cell phone use should be banned while driving a motor vehicle and tends to err in the coding of the reaction times in a way that favours this belief.This experimenter expectancy effect could be controlled by:

The double-blind procedure would control for the experimenter expectancy effect by ensuring that neither the participant nor the experimenter knows which group they are in (cell phone or no cell phone). This would prevent the research assistant from unconsciously favoring any particular group during the coding of the reaction times.
