  • The energy drink has reduced person A's reaction time. (I.E. it has made them react much faster)
  • The energy drink has increased person A's reaction time. (I.E. it has made them react much slower)
  • The energy drink had no effect on person A's reaction time. (I.E. it has had no effect)

  • Person B shows no change in their reaction times before and after drinking a caffeine energy drink. This is probably because person B had already consumed coffee before the experiment so their reactions were already fast due to the caffeine in the coffee.
  • Person B shows a change in their reaction times before and after drinking a caffeine energy drink. This is probably because person B had already consumed coffee before the experiment so their reactions were already fast due to the caffeine in the coffee.
  • Person B shows no change in their reaction times before and after drinking a caffeine energy drink. This is probably because person B had already consumed opioids before the experiment so their reactions were already fast due to the caffeine in the opioids.
