The second group is the control group, as they are not receiving the auditory feedback being tested in the experiment. The experimental group is the first group who are receiving the computer-simulated voice feedback. A placebo group would receive a fake treatment or intervention, which is not applicable in this experiment. A confederate is a person who is working with the experimenter but pretends to be a participant, which is also not relevant in this scenario.
