Four experiments, three cross-sectional and one longitudinal, tested the hypothesis that contemplating one’s own death produces a shift toward the use of positive emotion words. Participants who wrote about their own death, compared with those who wrote about dental pain, uncertainty, and meaningless, used more positive emotions words in their narratives (Experiments 1a and 1b). Experiment 2 found that contemplating one’s own death enhanced positive emotional word use across different mortality salience manipulations and remained consistent over the course of a 6-day study. Experiment 3 showed that the more positive emotion words participants used when contemplating their mortality, the greater worldview defense they showed. These results suggest that word use offers insight into how the mind responds to the salience of mortality.
