kottke.org: Procrastination vs. impatience

In one ingenious experiment, Oettingen had some of the participants rendered mildly dehydrated. They were then taken through an exercise that involved visualising drinking a refreshing, icy glass of water, while others took part in a different exercise. The dehydrated water-visualisers -- contrary to the self-help doctrine of motivation through visualisation -- experienced a significant reduction in their energy levels, as measured by blood pressure. Far from becoming more motivated to hydrate themselves, their bodies relaxed, as if their thirst were already quenched. In experiment after experiment, people responded to positive visualisation by relaxing. They seemed, subconsciously, to have confused visualising success with having already achieved it.
