The Experiment
  • 50 subjects, male and female, 18-65, diagnosed with PTSD
  • Split into 5 groups: red, yellow, green, blue, white*
  • Sit in colored room for 25 minutes
  • Weekly trials, rotations between rooms
  • Self report survey data on symptoms before and after

Expected results

  • Increased feelings of anger/fear after red
  • Increased irritability/isolation after yellow
  • Increased calmness/sadness after blue
  • Increased happiness after green

*as compared to white

  • Could all be placebo effect
  • Measure neurotransmitter/hormone levels before and after
