Experiment 7

A psychologist wants to examine the effects of meditation training and smoking status (smoker vs. non-smoker) on number of panic attacks experienced on a weekly basis for people with panic disorder from pretest to posttest. The psychologist recruits 30 people with panic disorder to participate (15 who identify as smokers and 15 who identify as non-smokers). All 30 participants record the number of panic attacks they experience per week for the 1 week prior to receiving meditation training (pretest assessment of panic attacks), they then all received meditation training, and complete an posttest assessment of number of panic attacks in the week following the meditation training. The psychologist wants to determine if smokers vs. non-smokers with panic disorder have more panic attacks, if there is a decrease in number of panic attacks per week from pretest to posttest assessment, and if the meditation training has a different effect on reducing panic attacks from pre to posttest for smokers vs. non-smokers.
