Abstract
This study examined the influence of temporal perspective and mood on the planning fallacy. Ninety-six Haverford students were randomly assigned to one of six experimental conditions, and received a paragraph writing task imbedded with two types of primes: temporal perspective (past, present, future) and mood (positive, negative). Participants were then asked to predict how much time it should take to complete a 100-piece jigsaw puzzle, and then actually completed the puzzle under timed conditions. Afterwards, participants made a retrospective duration estimate of the puzzle task. Among other hypotheses, it was predicted that subjects in the past negative condition would underestimate the task's duration the least, while subjects in the future positive condition would underestimate the most. The results did not support the hypotheses. Limitations and future directions are discussed.
