I CANNOT GET MY HEAD AROUND THIS QUESTION?

They gave half of their participants a stimulant, while the other half received a placebo. Within each drug condition, half of the participants were told the tablet they had taken was a stimulant, while the other half were told it was a depressant. Fifteen minutes after taking the tablets, all participants completed a standardised alertness questionnaire, producing a single alertness score.
