The Willpower Paradox: Possible and Impossible Conceptions of Self-Control

Challenging the law of least effort

Popular conceptions hold that effort is costly and aversive, causing people to generally avoid effort unless justified. We critically discuss evolutionary, phenomenological, and behavioral arguments supporting this "law of least effort", proposing that people may approach effort without direct extrinsic benefits. First, a "need for effort" is functional for health and learning. Second, experiencing contingency of effort and reward in the context of broader goals may lead to effort-seeking behavior. Moreover, beliefs with implications for the meaning of effort (e.g., as signaling difficulty or lack of talent) predict effort preferences. Thus, evolutionary, developmental, and social-cognitive factors may drive the pursuit of challenging goals that lie beyond life necessities but are essential for improvement and long-term development.

The power of cultural habits: The role of effortless control in delaying gratification

What factors lead children to delay gratification, holding out for larger rewards later instead of taking smaller rewards now? Traditionally, delay of gratification has been associated with effortful control and willpower. However, we propose that delay of gratification may be partially supported by effortless control employed through habits shaped within sociocultural contexts. Specifically, in sociocultural contexts where waiting is rewarding and socially valued, children are more likely to wait for larger, delayed rewards and to form associations between these contexts and waiting for rewards. These acquired habits enable waiting for rewards without requiring substantial cognitive effort. Based on this novel framework, we reconsider why childhood delay of gratification predicts life outcomes, and the role of cognitive, social, and cultural factors.

Self-control ≠ temporal discounting

This paper explores self-control beyond the framework of time discounting, as is conventional in economics and decision research. Contrary to the notion that self-control failures stem from hyperbolic time discounting or present bias, we argue that self-control problems represent conflicts between the motivational thrusts of affects - i.e., emotions, physiological states, and cognitive motivational feeling states - and deliberations about the best course of behavior. Drawing upon theoretical foundations and empirical evidence, we highlight how affective states can both undermine and necessitate self-control. We critique the temporal discounting model for its inability to account for diverse self-control scenarios and propose that effective self-regulation often involves strategies to avoid or manage affective triggers, thus providing a more comprehensive understanding of self-control mechanisms.

The dorsomedial prefrontal cortex promotes self-control by inhibiting the egocentric perspective

The dorsomedial prefrontal cortex (dmPFC) plays a crucial role in social cognitive functions, including perspective-taking. Although perspective-taking has been linked to self-control, the mechanism by which the dmPFC might facilitate self-control remains unclear. Using the multimodal neuroimaging dataset from the Human Connectome Project (Study 1, N =978 adults), we established a reliable association between the dmPFC and self-control, as measured by discounting rate-the tendency to prefer smaller, immediate rewards over larger, delayed ones. Experiments (Study 2, N = 36 adults) involving high-definition transcranial direct current stimulation showed that anodal stimulation of the dmPFC reduces the discounting of delayed rewards and decreases the congruency effect in egocentric but not allocentric perspective in the visual perspective-taking tasks. These findings suggest that the dmPFC promotes self-control by inhibiting the egocentric perspective, offering new insights into the neural underpinnings of self-control and perspective-taking, and opening new avenues for interventions targeting disorders characterized by impaired self-regulation.

No evidence for a reciprocal relationship between daily self-control failures and addictive behavior in a longitudinal study

Introduction

We all experience occasional self-control failures (SCFs) in our daily lives, where we enact behaviors that stand in conflict with our superordinate or long-term goals. Based on the assumption that SCFs share common underlying mechanisms with addictive disorders, we tested the hypothesis that a generally higher susceptibility to daily SCFs predicts more addictive behavior, or vice versa.

Methods

At baseline, 338 individuals (19-27 years, 59% female) from a community sample participated in multi-component assessments. These included among others (1) a clinical interview on addictive behaviors (quantity of use, frequency of use, DSM-5 criteria; n = 338) and (2) ecological momentary assessment of SCFs (n = 329, 97%). At the 3-year and 6 year follow-up, participation rates for both assessment parts were 71% (n = 240) and 50% (n = 170), respectively.

Results

Controlling for age, gender, IQ, and baseline addiction level, random-intercept cross-lagged panel models revealed that participants who reported more SCFs also showed pronounced addictive behavior at the between-person level, but we found no evidence of a predictive relationship at the within-person level over time.

Discussion

A higher rate of SCFs is associated with more addictive behavior, while there is no evidence of an intraindividual predictive relationship. Novel hypotheses suggested by additional exploratory results are that (1) only addiction-related SCFs in daily life are early markers of an escalation of use and thus for addictive disorders and that (2) an explicit monitoring of SCFs increases self-reflection and thereby promotes the mobilization of cognitive control in response to goal-desire conflicts.

The role of anticipated emotions in self-control: linking self-control and the anticipatory ability to engage emotions associated with upcoming events

Self-control is typically attributed to "cold" cognitive control mechanisms that top-down influence "hot" affective impulses or emotions. In this study we tested an alternative view, assuming that self-control also rests on the ability to anticipate emotions directed toward future consequences. Using a behavioral within-subject design including an emotion regulation task measuring the ability to voluntarily engage anticipated emotions towards an upcoming event and a self-control task in which subjects were confronted with a variety of everyday conflict situations, we examined the relationship between self-control and anticipated emotions. We found that those individuals (n = 33 healthy individuals from the general population) who were better able to engage anticipated emotions to an upcoming event showed stronger levels of self-control in situations where it was necessary to resist short-term temptations or to endure short-term aversions to achieve long-term goals. This finding suggests that anticipated emotions may play a functional role in self-control-relevant deliberations with respect to possible future consequences and are not only inhibited top-down as implied by "dual system" views on self-control.
