A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect.

We conducted a preregistered multilaboratory project ( = 36; = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the . Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( = 0.

Does state self-control depletion predict relationship functioning and partner aggression? An ecological momentary assessment study of community couples.

Intimate relationship functioning depends upon the ability to accommodate one's partner and to inhibit retaliatory and aggressive impulses when disagreements arise. However, accommodation and inhibition may be difficult when self-control strength is weak or depleted by prior exertion of self-control. The present study considered whether state self-control depletion prospectively predicts male and female self-reports of anger with partner and arguing with partner.

The Role of Past and Current Medical Use on Nonmedical Use of Prescription Drugs among College Students: Exploring Same-Drug and Cross-Drug Class Associations.

: Understanding the role that medical use of prescription drugs plays in nonmedical use of prescription drugs can inform prevention efforts. In order to understand fully the potential risk that medical use of prescription drugs conveys for nonmedical use of prescription drugs, the current study explored (a) the simultaneous associations between the medical use of several classes of prescription drugs with current nonmedical use of the same and other prescription drug classes, and (b) whether the associations depended upon past or current medical use. : Data came from a cross-sectional survey of 1686 college students, which assessed past and current medical use and current nonmedical use of stimulants, sedatives/anxiolytics, and opioid analgesics.

Mental Work Requires Physical Energy: Self-Control Is Neither Exception nor Exceptional.

The brain's reliance on glucose as a primary fuel source is well established, but psychological models of cognitive processing that take energy supply into account remain uncommon. One exception is research on self-control depletion, where debate continues over a limited-resource model. This model argues that a transient reduction in self-control after the exertion of prior self-control is caused by the depletion of brain glucose, and that self-control processes are special, perhaps unique, in this regard.

University student perceptions about the motives for and consequences of nonmedical use of prescription drugs (NMUPD).

Objective: The purpose of the current study was to increase qualitative understanding of student motives for and consequences associated with nonmedical use of prescription drugs.

Participants: Sixty-one students participated in eight focus groups between April and November 2013.

Methods: Students described prescription drugs commonly used for nonmedical reasons, as well as the motives for and consequences associated with their use.

Nonmedical use of prescription drugs and related negative sexual events: Prevalence estimates and correlates in college students.

The present study of college students investigated (a) the prevalence of nonmedical use of three classes of prescription drugs (stimulants, anxiolytics/sedatives, analgesics), (b) the prevalence of negative sexual events (NSE) associated with any nonmedical use of prescription drugs (NMUPD), and (c) a set of correlates of NSE. The specific NSE were sexual aggression victimization and perpetration, and regretted sex. The correlates of the NSE were sex, race/ethnicity, year in school, psychological symptoms, alcohol use, illegal drug use, and NMUPD.

Understanding maladaptive responses to rejection: Aggression with an audience.

Logically, responding aggressively to rejection is maladaptive because one is unlikely to seek a relationship with an aggressor. We predict that when concealed, the illogical aggressive response to rejection is more likely, whereas when the rejected individuals' aggressive responses are perceived as public, the aggressive acts may be reduced. Participants were rejected by others (Experiment 1) or were either accepted or rejected during an online ball-tossing game (Experiment 2) and were then given an opportunity to aggress publicly or privately.

The role of implicit affective responses and trait self-control in ego resource management.

Exertion of self-control requires reliance on ego resources. Impaired performance typically results once those resources have been depleted by previous use. Yet the mechanism behind the depletion processes is little understood.

Rude and inappropriate: the role of self-control in following social norms.

Following social norms to avoid deviant or socially inappropriate behavior may require self-control. This was tested in two experiments that experimentally manipulated individuals' level of self-control strength. In the first experiment, individuals whose self-control capacity was depleted were more likely to misrepresent how many problems they solved and work after being told to stop while working on a timed test.

Practicing self-control lowers the risk of smoking lapse.

Recent research has suggested that practicing small acts of self-control can lead to an improvement in self-control performance. Because smoking cessation requires self-control, it was hypothesized that a treatment that builds self-control should help in quitting smoking. A total of 122 smokers either practiced small acts of self-control for 2 weeks before quitting smoking or practiced a task that increased their awareness of self-control or feelings of confidence, without exercising self-control.

Emotion differentiation as resilience against excessive alcohol use: an ecological momentary assessment in underage social drinkers.

Some people are adept at using discrete emotion categories (anxious, angry, sad) to capture their felt experience; other people merely communicate how good or bad they feel. We theorized that people who are better at describing their emotions might be less likely to self-medicate with alcohol. During a 3-week period, 106 underage social drinkers used handheld computers to self-monitor alcohol intake.

Building Self-Control Strength: Practicing Self-Control Leads to Improved Self-Control Performance.

Self-control performance may be improved by the regular practice of small acts of self-control. Ninety-two adults' self-control capacity was assessed using the stop signal paradigm before they started practicing self-control and again at the end of two weeks. Participants who practiced self-control by cutting back on sweets or squeezing a handgrip exhibited significant improvement in stop signal performance relative to those who practiced tasks that did not require self-control.

Autonomous Self-Control is Less Depleting.

Autonomously motivated self-control may be less depleting than extrinsically motivated self-control. Participants were asked to not eat cookies and their motivation orientation for resisting that temptation was assessed. Their self-control performance was assessed immediately before and after fighting the temptation.

Helpful Self-Control: Autonomy Support, Vitality, and Depletion.

Why someone exerts self-control may influence how depleting a task is. Feeling compelled to exert self-control require more self-control strength than exerting self-control for more autonomous reasons. Across three experiments, individuals whose autonomy was supported while exerting self-control performed better on a subsequent test of self-control as compared to individuals who had more pressure placed upon them while exerting self-control.

Conserving self-control strength.

Individuals may be motivated to limit their use of self-control resources, especially when they have depleted some of that resource. Expecting to need self-control strength in the future should heighten the motivation to conserve strength. In 4 experiments, it was found that depleted participants who anticipated exerting self-control in the future performed more poorly in an intervening test of self-control than participants who were not depleted, and more poorly than those who did not expect to exert self-control in the future.

The self-control costs of fighting the temptation to drink.

Being exposed to the sight and smell of an alcoholic beverage and not drinking it should require self-control. On the basis of the self-control strength model (M. Muraven & R.

Capturing the moment: innovative approaches to daily alcohol assessment.

This article is a summary of a symposium presented at the 2005 Research Society on Alcoholism annual conference organized by Dan J. Neal and chaired by William R. Corbin.

The morning after: limit violations and the self-regulation of alcohol consumption.

The authors examined whether the reciprocal relationship between alcohol consumption and distress unfolded over time in 2 samples of social drinkers. Participants monitored their alcohol intake and their cognitive and emotional responses to that drinking on hand-held computers. On mornings after drinking, those who had violated their self-imposed limits the day before reported more guilt, even after controlling for acute negative symptoms of drinking and amount consumed.

Daily fluctuations in self-control demands and alcohol intake.

Predictions made by the self-control strength model were tested in a sample of underage social drinkers using ecological momentary assessment methodology. On days that participants experienced more self-control demands than average, they were more likely to violate their self-imposed drinking limit after controlling for mood and urge to drink. There was no relationship between self-control demands and urge or intention to drink, nor were self-control demands related to plans to limit drinking.

One too many: predicting future alcohol consumption following heavy drinking.

Adult social drinkers used handheld computers to monitor alcohol intake as well as the precursors and consequences of drinking over a 2-week period. The within-person relationship between mood and amount of alcohol consumed was examined, as well as the role of individual differences. When individuals made internal attributions for their greater than average consumption, they were in a more negative mood after drinking.

Mechanisms of self-control failure: motivation and limited resources.

Research has found that individuals who are lower in self-control strength because of previous self-control exertions perform more poorly on subsequent tests of self-control. The present studies suggest that this effect may be moderated by motivation. In particular, depletion and motivation jointly determine self-control performance.

Self-control and alcohol restraint: an initial application of the self-control strength model.

Individuals whose self-control strength is depleted through the prior exertion of self-control may consume more alcohol in situations that demand restraint. Male social drinkers either exerted self-control by suppressing their thoughts or did not exert self-control while doing arithmetic. They then sampled beer.
