LABORATORY EXERCISE 5 Do colors affect mood? You are particularly interested to know which color gives people a sense of serenity and peacefulness. You conduct an experiment by making participants stay for 20 minutes inside a room painted with a particular color (e.g., Red, Orange, Yellow, Green, Blue). With the use of temperature-sensitive cameras, you record the average body temperature of each individual during their stay inside each room (i.e., lower body temperatures are associated with feelings of calmness and relaxation; higher body temperatures - stimulation, excitement). Reculte are presented on the table. Red 43 39 41 42 45 Orange 39 43 44 35 40 39 Yellow 38 39 42 39 39 38 Green 33 35 34 37 36 33 Bluf 31 34 32 32 35 34 A.
