A stylus punch-board maze was the medium for the induction of satiation. Satiation was operationally defined: an individual was satiated when he rejected an activity which was initially pursued, and reported or exhibited characteristic attitudes of satiation. Under the conditions represented 87% of the satiated subjects of two experiments under-estimated the time required for them to become satiated. 52% of a non-satiated group of subjects overestimated the time required for them to achieve the criterion of learning. The greater underestimation than overestimation of time by satiated subjects does not appear to be fully explained by the theory that underestimation is characteristic of those who can divorce themselves from the satiating activity; those who cannot leave the behavioral field, on the other hand, overestimate time. A theory of satiation based upon the belief in total consistent trends in time estimation, and in the operation of a single causative factor in judgments of time, does not seem to be warranted.
