Self-control is positively associated with a host of beneficial outcomes. Therefore, psychological interventions that reliably improve self-control are of great societal value. A prominent idea ...suggests that training self-control by repeatedly overriding dominant responses should lead to broad improvements in self-control over time. Here, we conducted a random-effects meta-analysis based on robust variance estimation of the published and unpublished literature on self-control training effects. Results based on 33 studies and 158 effect sizes revealed a small-to-medium effect of g = 0.30, confidence interval (CI 95) 0.17, 0.42. Moderator analyses found that training effects tended to be larger for (a) self-control stamina rather than strength, (b) studies with inactive compared to active control groups, (c) males than females, and (d) when proponents of the strength model of self-control were (co) authors of a study. Bias-correction techniques suggested the presence of small-study effects and/or publication bias and arrived at smaller effect size estimates (range: gcorrected =. 13 to. 24). The mechanisms underlying the effect are poorly understood. There is not enough evidence to conclude that the repeated control of dominant responses is the critical element driving training effects.

Is Ego Depletion Real? An Analysis of Arguments Friese, Malte; Loschelder, David D.; Gieseler, Karolin ...

An influential line of research suggests that initial bouts of self-control increase the susceptibility to self-control failure (ego depletion effect). Despite seemingly abundant evidence, some ...researchers have suggested that evidence for ego depletion was the sole result of publication bias and p-hacking, with the true effect being indistinguishable from zero. Here, we examine (a) whether the evidence brought forward against ego depletion will convince a proponent that ego depletion does not exist and (b) whether arguments that could be brought forward in defense of ego depletion will convince a skeptic that ego depletion does exist. We conclude that despite several hundred published studies, the available evidence is inconclusive. Both additional empirical and theoretical works are needed to make a compelling case for either side of the debate. We discuss necessary steps for future work toward this aim.

Abundant research has established that first proposals can anchor negotiations and lead to a first-mover advantage. The current research developed and tested a motivated anchor adjustment hypothesis ...that integrates the literatures on framing and anchoring and highlights how anchoring in negotiations differs in significant ways from standard decision-making contexts. Our research begins with the premise that first proposals can be framed as either an offer of resources (e.g., I am offering my A for your B) that highlights gains versus a request for resources (e.g., I am requesting your B for my A) that highlights losses to a responder. We propose that this framing would affect the concession aversion of responders and ultimately the negotiated outcomes. We predicted that when a first proposal is framed as an offer, the well-documented anchoring and first-mover advantage effect would emerge because offers do not create high levels of concession aversion. In contrast, because requests highlight what the responder has to give up, we predicted that opening requests would produce concession aversion and eliminate and even reverse the first-mover advantage. Across 5 experiments, the classic first-mover advantage in negotiations was moderated by the framing of proposals because anchor framing affected concession aversion. The studies highlight how motivational forces (i.e., concession aversion) play an important role in producing anchoring effects, which has been predominantly viewed through a purely cognitive lens. Overall, the findings highlight when and how motivational processes play a key role in both judgmental heuristics and mixed-motive decision-making.

When confronted with others' fortunes and misfortunes, emotional reactions can take various forms-ranging from assimilative (happy-for-ness, sympathy) to contrastive emotions (envy, schadenfreude) ...and from prosocial (reward) to antisocial behavior (punish). We systematically tested how social comparisons shape reactions to others' (mis)fortunes with a newly developed paradigm with which we investigated envy, happy-for-ness, schadenfreude, and sympathy in a joint rigorous experimental setup, along with individuals' ensuing behavioral reactions. In nine experiments (N
total = 1,827), (a) participants' rankings on a comparison dimension relative to other people and (b) others' (mis)fortunes (changes in relative rankings) jointly determined how much individuals experienced the emotions. Upward comparisons increased envy and schadenfreude, and downward comparisons increased sympathy and happy-for-ness, relative to lateral comparisons. When the relevance of comparison standards (Experiment 4a) or the comparison domain (Experiment 4b) was low, or when participants did not have their own reference point for comparison (Experiment 4c), the effect of comparison direction on emotions was attenuated. Emotions also predicted the ensuing behavior: Envy and schadenfreude predicted less, whereas happy-for-ness and sympathy predicted more prosocial behavior (Experiments 5 and 6). Overall, the strongest social comparison effects occurred for envy and sympathy, followed by schadenfreude and happy-for-ness. The data suggest that envy and sympathy arise when comparative concerns are threatened, and happy-for-ness and schadenfreude arise when they are satisfied (because inequality increases vs. decreases, respectively) and predict behavior aimed at dealing with these concerns. We discuss implications for the function of fortunes-of-others emotions, social comparison theory, inequity aversion, and prospect theory.

Objective: Maintaining safe physical distance is paramount to slowing the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/coronavirus disease 2019 (COVID-19), particularly ...indoors (e.g., while shopping). We used a health message intervention to motivate grocery store customers to engage in distancing behavior. Method: In an online experiment (N = 206) and a field experiment (N = 268; preregistered on OSF), we used a 2 × 2 between-subjects design and manipulated health messages (a) as gain-framed ("to foster health") versus loss-framed ("it could be deadly") and (b) as targeting different beneficiaries (customers themselves versus fellow citizens). In the field experiment, observers rated customers' distancing behavior during a random confederate encounter and a subsequent interview. We assessed customers' perceptions of risk and worry, perspective-taking, and state optimism as concurrent psychological processes to investigate customers' distancing behavior in correlational mediation analyses. Results: Contrary to previous research, the intervention was more effective when pertaining to customers themselves than to their fellow citizens (Experiments 1-2). In addition, loss-framed messages were more effective than gain-framed ones (Experiment 2). The former behavioral effect was accompanied (and statistically mediated) by a concurrent psychological increase in customers' perceived risk and worry. Conclusions: Owing to their low cost and easy implementation, health messages constitute a promising means to promote physical distancing. Our results show that their effectiveness significantly depends on the framing and target of the health behavior.

•Plastic to-go-cups constitute a severe threat to sustainable consumption.•Behavioral economics suggests to nudge consumers via dynamic norms.•A large-sampled, pre-registered intervention study ...replicates the dynamic norms effect.•Customers were nudged to use 17.3% more reusable mugs over disposable cups.•An experiment shows dynamic norms outperform static and static + injunctive norms.
Excess use of disposable to-go-cups constitutes a severe sustainability threat. Behavioral economics and economic psychology suggest various antidotes. In the present paper, we report two studies – a large-scale intervention field study and an experiment – that constitute independent, pre-registered, and open replication attempts of a recently-introduced intervention procedure: dynamic social norms. We tested whether a dynamic norm, along the lines of “more and more customers are switching from to-go-cups to a sustainable alternative. Be part of this movement and choose a reusable mug” – can help café customers to avoid disposable to-go-cups. Data from a fourteen-week intervention experiment with a total of 23,946 hot beverages sold – 18,019 in disposable cups and 5927 in reusable mugs – suggest that a dynamic-norm intervention for sustainable consumption helps customers avoid disposable cups and increases their use of reusable alternatives by 17.3% (or 4.1 percentage points). A follow-up online experiment corroborates this pattern and shows advantageous effects of a dynamic norm relative to a no-norm control condition, a static norm, an injunctive norm, and a combination of static-and-injunctive norm. In light of inconsistent and, at times, failed or even reversed replication results for seminal social norms studies, the present pre-registered studies indicate that dynamic norms are an effective means to facilitate sustainable behavior. We discuss scientific and applied implications and avenues for future research.

Few spheres in life are as universally relevant for (almost) all individuals past puberty as sexuality. One important aspect of sexuality concerns individuals' sex drive-their dispositional sexual ...motivation. A vigorous scientific (and popular) debate revolves around the question of whether or not there is a gender difference in sex drive. Several theories predict a higher sex drive in men compared to women, with some theories attributing this difference to biased responding rather than true differences. Currently, there is little consensus on how to conceptualize sex drive, nor does a quantitative summary of the literature exist. In this article, we present a theory-driven conceptualization of sex drive as the density distribution of state sex drive, where state sex drive is defined as momentary sexual motivation that manifests in sexual cognition, affect, and behavior. We conduct a comprehensive meta-analysis of gender differences in sex drive based on 211 studies, 856 effect sizes, and 621,463 persons. The meta-analysis revealed a stronger sex drive in men compared to women, with a medium-to-large effect size, g = 0.69, 95% CI 0.58, 0.81. Men more often think and fantasize about sex, more often experience sexual affect like desire, and more often engage in masturbation than women. Adjustment for biased responding reduced the gender difference (g = 0.54). Moderation analyses suggest that the effect is robust and largely invariant to contextual factors. There was no evidence of publication bias. The discussion focuses on validity considerations, limitations, and implications for psychological theory and people's everyday lives.
Public Significance Statement
This article explains sex drive from a scientific, psychological perspective-operationalized as sexual thoughts, desire, and masturbation frequency-and provides support using a meta-analytic review that men have a stronger sex drive than women. Some but not all of these gender differences may be caused by men overreporting and/or women underreporting their sex drive. These findings advance our understanding of sexual dynamics in interpersonal relationships and society at large.

Smartphones cause self-control challenges in people's everyday lives. Supporting this notion, our studies corroborate that trait self-control is negatively associated (1) with students' distraction ...(via smartphones) during their learning endeavors (Study 1, N = 446) and (2) with several aspects of problematic smartphone-use (Study 2, N = 421). Study 3 (N = 106) investigated whether distinct aspects of smartphone-use also account for the link between students' trait self-control and academic performance. Specifically, we examined (1) smartphone procrastination (i.e., irrational task delays via smartphone), (2) beneficial smartphone habits (placing in a bag placement habit or turning the sound off setting habit), and (3) the objective amount of smartphone-use (minutes spent on the smartphone screentime and times picked up pickups). In line with our predictions, students higher in trait self-control showed better academic performance (β = 0.22). Smartphone procrastination (β = −0.23) and placement habits (β = 0.21) were significantly associated with academic performance and both also mediated the self-control-performance-link. Our findings suggest that it is not the objective amount of smartphone-use but the effective handling of smartphones that helps students with higher trait self-control to fare better academically. Implications for future research are discussed from a self-regulatory perspective on smartphone-use.
•Trait self-control was linked to students' smartphone-use and academic performance.•We contrast the effects of how much versus how of smartphone-use on performance.•Procrastination and placement habits explain the self-control-performance-link.

Past research has suggested a fundamental principle of price precision: The more precise an opening price, the more it anchors counteroffers. The present research challenges this principle by ...demonstrating a too-much-precision effect. Five experiments (involving 1,320 experts and amateurs in real-estate, jewelry, car, and human-resources negotiations) showed that increasing the precision of an opening offer had positive linear effects for amateurs but inverted-U-shaped effects for experts. Anchor precision backfired because experts saw too much precision as reflecting a lack of competence. This negative effect held unless first movers gave rationales that boosted experts' perception of their competence. Statistical mediation and experimental moderation established the critical role of competence attributions. This research disentangles competing theoretical accounts (attribution of competence vs. scale granularity) and qualifies two putative truisms: that anchors affect experts and amateurs equally, and that more precise prices are linearly more potent anchors. The results refine current theoretical understanding of anchoring and have significant implications for everyday life.

Employees around the globe experience manifold challenges to maintain job performance during the so‐called work‐from‐home experiment caused by the COVID‐19 crisis. Whereas the self‐control literature ...suggests that higher trait self‐control should enable employees to deal with these demands more effectively, we know little about the underlying mechanisms. In a mixed‐methods approach and two waves of data collection, we examine how self‐control strategies elucidate the link between teleworking employees' trait self‐control and their job performance. Using a qualitative approach, we explored which strategies employees use to telework effectively (N = 266). In line with the process model of self‐control, reported strategies pertained to situation modification (i.e., altering the physical, somatic, or social conditions) and cognitive change (i.e., goal setting, planning/scheduling, and autonomous motivation). Subsequent preregistered, quantitative analyses with a diverse sample of 106 teleworkers corroborated that higher trait self‐control is related to job performance beyond situational demands and prior performance. Among all self‐control strategies, modifying somatic conditions and autonomous motivation was significantly associated with job performance and mediated the self‐control‐performance link. This research provides novel insights into the processes by which employees productively work from home and inspires a broad(er) view on the topic of self‐control at work.
