You want to find out if music enhances problem solving. Subjects will be recruited and randomly assigned to one of four groups: Those in Group 1 will serve as the control group and will be given a standard 100-piece jigsaw puzzle to solve in a quiet room. Participants in Group 2 will be given the same puzzle to assemble, but instead of silence, there will be classical music playing at a soft volume (30 decibels [dB]) in the room. Participants in Group 3 will be given the same puzzle to assemble using the same classical music, but the music will be played at a moderate volume (60 dB). Participants in Group 4 will be given the same puzzle to assemble using the same classical music, but the music will be played at a loud volume (90 dB). You will record the time (in seconds) that it takes for each person to complete the puzzle.
