Dr. Jefferson's dependent variable in this experiment is the performance on the mental rotation task. In other words, she is measuring how well the participants perform on the mental rotation task after consuming either the caffeine pill or the placebo pill. The dependent variable is the outcome or the response variable that she is interested in, as it may be affected by the independent variable, which is the administration of different pills (caffeine vs. placebo) in this case.
