You want to determine if watching a video of a comedy with a laugh track enhances enjoyment. Subjects will be recruited and randomly assigned to one of three groups: Those in Group 1 (the control group) will watch the video without the laugh track, those assigned to Group 2 will watch the same video with the sound of a 50-person audience included in the soundtrack, and those assigned to Group 3 will watch the same video with the sound of a 100-person audience included in the soundtrack. Each participant will watch the video individually; no others will be present in the room. Immediately following the video, each participant will be asked to rate how enjoyable the show was on a scale of 1 to 5 (1 = not very enjoyable, 5 = very enjoyable).
