Presidential address 2013: Fatigue influence on effort- considering implications for self-regulatory restraint

摘要

I sketch here an analysis of fatigue influence on effort and apply it to the phenomenon of self-regulatory restraint, construing such restraint as resistance against a behavioral urge or impulse. The analysis suggests that fatigue does not have a single influence, but rather a multifaceted one dependent on the difficulty of the task at hand and the importance of accomplishing it. Application to self-regulatory restraint offers a novel and potentially significant understanding of how the phenomenon works. A key implication is that restraint intensity should vary proximally with the magnitude of the urge resisted. Another is that fatigue and other restraint ability factors should have different influences on restraint intensity depending on the magnitude of an urge and the importance of resisting it. Cardiovascular results from ability and fatigue studies attest to the validity of the fatigue analysis and support its application in the self-regulatory context.
