Figure 1.6 Changes in Perception of Exercise in Hotel Experiment The two graphs below show the changes in the perceptions of the experimental group participants, who were informed about the health benefits of work-related exercise during the first session. Even though their behavior at work and outside of work did not change, the new information increased their perceptions of how much regular exercise they were getting and that work-related tasks were a form of exercise. In comparison, perceptions were unchanged in the control group participants, who did not receive information about the health benefits of work-related exercise.

Control group participants, who were not told about the health benefits of work-related exercise, showed no changes on the same measures.
