According to the resource-depletion model, self-control is a limited resource that is depleted after a period of exertion. Evidence consistent with this model indicates that self-control relies on glucose metabolism and glucose supplementation to depleted individuals replenishes self-control resources. In five experiments, we tested an alternative hypothesis that glucose in the oral cavity coun...

Nutrient limitation to primary productivity and other biological processes is widespread in terrestrial ecosystems, and nitrogen (N) and phosphorus (P) are the most common limiting elements, both individually and in combination. Mechanisms that drive P limitation, and their interactions with the N cycle, have received less attention than mechanisms causing N limitation. We identify and discuss ...

Current research into self-control that is based on the sequential task methodology is currently at an impasse. The sequential task methodology involves completing a task that is designed to tax self-control resources which in turn has carry-over effects on a second, unrelated task. The current impasse is in large part due to the lack of empirical research that tests explicit assumptions regard...

How to best exploit patchy resources? We introduce a minimal exploitation-migration model that incorporates the coupling between a searcher's trajectory, modeled by a random walk, and ensuing depletion of the environment by the searcher's consumption of resources. The searcher also migrates to a new patch when it takes S consecutive steps without finding resources. We compute the distribution o...

OBJECTIVE The difficulty for chronic dieters (i.e. restrained eaters) in regulating their food intake is a conflict between two apparently incompatible goals: eating enjoyment and weight control. The latter goal consistently relies on the deployment of cognitive resources, and very often on a significant amount of self-control. This study investigated whether self-affirmation might counteract t...

Energy consumption has always a noticeable impact on the environment. Fast growing world population, increasing prosperity and the hunger for fuel that has developed a consequence, have led to a rapid rise in the need for energy, so to fulfill that need we require renewable resources. The non-conventional or alternative energy resources are not amenable to depletion even with irrational levels ...

We study the evolution of cooperation in the collective-risk social dilemma game, where the risk is determined by a collective target that must be reached with individual contributions. All players initially receive endowments from the available amount of common resources. While cooperators contribute part of their endowment to the collective target, defectors do not. If the target is not reach...

a r t i c l e i n f o In the realm of self-regulation, recent work shows that the state of ego depletion can be vicariously transmitted from a target to a perceiver simply by imagining the perspective of a depleted target (i.e., vicarious depletion ; Ackerman et al., 2009). The present study asked whether such vicarious effects can extend to the domain of self-regulatory recovery. In Experiment...

The purpose of the present study is to examine the effects of ego depletion on arousal of elite Iranian swimmers. The sample comprised elite swimmers invited to the national swimming team as focused and semi focused (36 subjects). The research design was as pre- and post-test—in two phases of ego depletion conditions and the lack of ego depletion conditions in two experimental and control...
