A researcher examines the effects of controlled breaks on reaction times of Air Traffic Controllers. The controllers are randomly assigned to two groups. Group 1 has 20 controllers who spend 45 minutes on a break in a quiet room, with no talking, TV, or other electronics. Group 2 has 20 controllers who spend their 45 minutes on a break in a common area break room where people are allowed to talk, watch TV, or use electronic devices. Following the breaks, each group of controllers returned to their shift where their reaction times were assessed.
