Visualizing behavior from a third-person (vs. first-person) perspective can produce stronger
motivation to enact the behavior. However, the effects of perspective on health behaviors
have been mixed. Hypothesizing that the difficulty of the visualized behavior might moderate
the effect of perspective, two experiments manipulated the difficulty of the visualized
behaviors (fruit/vegetable consumption; exercise) plus perspective and subsequently
measured motivation (Experiments 1 and 2) and behavior (Experiment 2). In both
experiments, the third-person perspective produced stronger motivation to perform the easier,
but not the more difficult, behavior. This effect extended to behavior in Experiment 2. Under
certain conditions, encouraging people to visualize behavior from a third-person perspective
could represent a useful and cost-effective means of promoting health behavior chang
