Question 2

Dr. Caster decides to perform an experiment investigating the effects of caffeine and sugar on motor skill performance. He randomly assigns his subjects to one of four groups: high caffeine/high sugar, high caffeine/no sugar, no caffeine/high sugar, no caffeine/no sugar. People in each group are given a soft drink containing the appropriate levels of sugar and caffeine, and then tested on a mirror tracing task. Dr. Caster finds that the people in two of the groups (the high caffeine/high sugar and the no caffeine/no sugar) perform at about the same high level, while the other two groups (the no caffeine/high sugar and high caffeine/no sugar) perform at about the same poor level. Dr. Caster's results show
 
  a. a main effect of caffeine
  b. a main effect of sugar
  c. a synergistic interaction
  d. an antagonistic interaction
