A tale of two tasks: reversing the self-regulatory resource depletion effect

Abstract

This research examined the self-regulatory depletion model (e.g., M. Muraven & R. F. Baumeister, 2000). Although numerous studies support this model's prediction of decrements in self-regulation across tasks, the majority of this research has relied on a single paradigm in which two tasks are performed in succession. Other work related to learned industriousness (R. Eisenberger, 1992) and adaptation-level theory (H. Helson, 1964) indicates that self-regulatory behavior may remain stable or even improve as a result of prior self-regulatory activities in situations involving additional tasks. Three studies examined these differing perspectives with 2- and 3-task designs. Results indicated that, relative to low initial self-regulatory exertion, high exertion can lead to poorer or better subsequent self-regulation. These findings are consistent with an adaptation view of self-regulation, suggesting that the depletion effect may be only part of the picture of self-regulatory behavior over time.
