Some complex thinking requires active guidance by the self, but simpler mental activities do not. Depletion of the self's regulatory resources should therefore impair the former and not the latter. Resource depletion was manipulated by having some participants initially regulate attention (Studies 1 and 3) or emotion (Study 2). As compared with no-regulation participants who did not perform such exercises, depleted participants performed worse at logic and reasoning (Study 1), cognitive…

Ego depletion and the use of mental contrasting

Mentally contrasting a desired future with present reality leads to goal pursuit in accordance with people’s expectations of realizing the desired future. Because mental contrasting is a purposeful

Ego depletion improves insight

ABSTRACT Initial acts of self-control can reduce effort and performance on subsequent tasks – a phenomenon known as ego depletion. Ego depletion is thought to undermine the capacity or willingness to

Saving Resources for Future Demands—The Role of Instruction, Cognitive Load and Metacognition

Two studies test the hypothesis of conserving resources while performing depleting physical tasks and the modifying role of metacognitive self (MCS). A total of 216 undergraduate students performed

Too exhausted to remember: ego depletion undermines subsequent event-based prospective memory.

It is proposed that the initial actions of self-control may undermine subsequent event-based prospective memory (EBPM), and the effect of ego depletion on EBPM was mainly due to an impaired prospective component rather than to a retrospective component.

A new perspective on the interplay between self-control and cognitive performance: Modeling progressive depletion patterns

The results provide evidence that the self-control invested in order to keep performance at a consistently high level wanes over time, and provide an alternative approach that may help future researchers to investigate the underlying mechanisms of self- control.

Ego Depletion and Positive Illusions: Does the Construction of Positivity Require Regulatory Resources?

It is proposed that positive illusions require resources of self-control, which is considered to be a limited resource similar to energy or strength.

Ego Depletion Impairs Implicit Learning

The results indicate that performance on an implicitly learned sequence can be impaired by a reduction in executive resources, in spite of learning taking place outside of awareness and without conscious intent.

Ego depletion negatively affects knowledge retrieval in secondary school students

Abstract In the present study, we tested the assumption that performance in a knowledge retrieval test would be lower in secondary school students with temporarily depleted self-control strength (n =



Effects of social exclusion on cognitive processes: anticipated aloneness reduces intelligent thought.

The effects were specific to social exclusion, as participants who received predictions of future nonsocial misfortunes (accidents and injuries) performed well on the cognitive tests and appeared to involve reductions in both speed (effort) and accuracy.

Ego depletion: is the active self a limited resource?

The results suggest that the self's capacity for active volition is limited and that a range of seemingly different, unrelated acts share a common resource.

Beyond behaviorism: on the automaticity of higher mental processes.

The authors consider the common philosophical commitment to determinism by both schools of thought, and how the radical behaviorists' thesis of the determined nature of higher mental processes is being pursued today in social cognition research on automaticity.

Behavioral inhibition, sustained attention, and executive functions: constructing a unifying theory of ADHD.

A theoretical model that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution is constructed and finds it to be strongest for deficits in behavioral inhibition, working memory, regulation of motivation, and motor control in those with ADHD.

Exploring the Central Executive

The central executive component of working memory is a poorly specified and very powerful system that could be criticized as little more than a homunculus. A research strategy is outlined that

Self-Regulatory Failure: A Resource-Depletion Approach

Three studies were conducted to test the behavioral consequences of effortful self-regulation. Individuals with chronic inhibitions about eating were exposed to situations varying in level of

Consciousness and Self-Regulation: Advances in Research and Theory IV

This book discusses the influence of cardiac Afferent Influences on Consciousness, Mechanisms of Biofeedback Control, and the importance of Verbal (Conscious) Processing in learning and long-term Physiological Regulation.

Mental models and logical reasoning problems in the GRE

The mental model theory of reasoning is applied to the analysis of logical reasoning problems and predicts 3 main causes of difficulty, which were corroborated by the results of 4 experiments: the nature of the logical task, the set of foils, and thenature of the conclusions.

Of Thoughts Unspoken Social Inference and the Self-Regulation of Behavior

How do attempts to regulate one's own behavior affect the inferences one draws about others? We suggest that perceivers draw dispositional inferences about targets (characterization) and then adjust
