26 to 50 of 344Attenuated brain activity during error processing and punishment anticipation in procrastination - a monetary Go/No-go fMRI study.
Procrastination is a self-regulatory failure in which people voluntarily but irrationally delay important tasks. Trait procrastination is estimated to affect 15-20% of the total population and leads to a significant decrease in performance, satisfaction with achievements, and quality of life. Procrastination is related to impulsivity and reduced executive control, especially in the domain of inhibition. Moreover, procrastinatory tendencies seem to increase with negative affect, suggesting impaired emotion regulation. The aim of this study was to investigate the neuronal mechanisms of inhibition, error processing, and behavioral control under pressure of punishment in procrastinators. Non-student subjects recruited to low (LP) and high procrastination (HP) groups performed an fMRI monetary Go/No-go task. HP showed significantly lower error-related activity in ACC than LP. There was also a…

Internet-based self-help intervention for procrastination: randomized control group trial protocol.
Background: Procrastination or "postponing until later" is a common phenomenon defined as the intentional delay in partaking in and finishing important activities despite negative outcomes potentially outweighing the positive. Procrastination adversely affects mental health, academic performance, and career achievement. Although studies on procrastination intervention methods and effectiveness exist, utility and cost-effectiveness are limited by various factors, including practitioner availability and skills, barriers to participant participation, and the time investment required by participants. Thus, internet-based interventions could increase the availability of evidence-based treatments for adult procrastination.
Methods: This study explored the efficacy of an online-based self-help intervention in the context of voluntary procrastination among undergraduate psychology students. The …

Evaluating the effectiveness of a brief digital procrastination intervention targeting university students in Sweden: study protocol for the Focus randomised controlled trial.
Introduction: The concept of procrastination can be described as a conscious, yet irrational, postponement of important tasks or decisions-despite awareness that the delay may lead to negative consequences. Procrastination behaviours are common among university students and is often described as a failure of self-regulation, and the behaviour is associated with stress, symptoms of depression and anxiety, poorer academic performance and negative effects on overall health and well-being.
Methods and analysis: A two-arm, parallel groups (1:1), single-blind randomised controlled trial will be conducted to assess the effectiveness of a brief digital procrastination intervention (Focus) among university students in Sweden. The intervention consists of a screening and feedback component based on Pure Procrastination Scale (PPS) score, allowing intervention participants to assess their current p…

Zacks S, Hen M (2018)reviewMEDLINE-indexed journal, not yet read by usJournal of prevention & intervention in the community27 citations Academic interventions for academic procrastination: A review of the literature.
Procrastination is a widespread phenomenon in academic settings. It has been studied from many different theoretical angles, and a variety of causes and consequences have been suggested. Recent studies support the notion that academic procrastination can be seen from a situational perspective and as a failure in learning self-regulation. It suggests that interventions should address situational as well as deficits in self-regulation to help students overcome their procrastinating tendencies. The present review examined the recent literature on causes and consequences of academic procrastination and the limited number of studies of academic interventions for academic procrastination. Findings of this review strengthen the need to further study the topic of academic interventions for academic procrastination and to develop effective interventions. At the end of this review, several suggest…

The effect of ego depletion on challenge and threat evaluations during a potentially stressful public speaking task.
It has been well established that challenge and threat evaluations affect the performance of potentially stressful tasks. However, the factors that influence these evaluations have rarely been examined. Objective: This study examined the effects of ego depletion on challenge and threat evaluations during a public speaking task. Method: 262 participants (150 males, 112 females; Mage = 20.5, SD = 4.3) were randomly assigned to either an ego depletion or control group. Participants then completed self-report measures of trait self-control. The ego depletion group performed a written transcription task requiring self-control, while the control group transcribed the text normally. Before the public speaking task, participant's challenge and threat evaluations and subjective ratings of performance were assessed via self-report items. Results: The results of independent t-tests supported the ef…

Ego depletion and the use of force: Investigating the effects of ego depletion on police officers' intention to use force.
The current study aims to investigate corresponding self-control and self-control failures that are the result of ego depletion and its impact on police officers' decision to use force. For that purpose, a total of 200 German police recruits were randomly assigned to either an experimental or control group. Ego depletion was manipulated using the "e" crossing task. Participants then worked through a video-based scenario exercise, in which they encountered a provocative citizen. They were required to indicate the time that they would take to resort to using force to resolve the situation. Results showed that ego depleted officers intended to use force earlier than controls. This indicates that circumstances that produce ego depletion could lead to the inappropriate use of force by reducing self-control. This has major implications for the police use of force and how we understand police o…

Unwilling but not unable to control: Ego depletion increases effortful dishonesty with material rewards.
Previous studies have found that ego depletion increases dishonesty. However, it remains unclear whether ego depletion makes participants unable to exert self-control or unwilling to exert self-control when it increases dishonesty. The present study aimed to clarify this. Based on the process model, ego depletion causes individuals to pay more attention to material rewards and increases the motivation to act on impulse. Therefore, it is possible that ego-depleted participants are unwilling, rather than unable, to be honest. We conducted two experiments to examine this hypothesis. Results showed that ego depletion increased material-based dishonesty even when the dishonest behavior was more complicated and effortful than was the honest behavior. However, participants were reluctant to cheat just for convenience, and ego depletion had no apparent effect on convenience-based dishonesty with…

Attentional bias is more predictive of eating behavior after self-control exertion.
There is experimental evidence to suggest that attentional bias to food stimuli may predict food intake. The process model of ego-depletion (Inzlicht & Schmeichel, 2012) proposes that after self-control exertion, attention shifts toward rewarding objects such as palatable food, which in turn should prompt greater food consumption as an indicator of lower self-control. In the current study, 84 female restrained and unrestrained eaters engaged in a self-control or neutral task, followed by a measure of attentional bias and an eating task. Results indicated there were no differences in attentional bias or amount eaten between self-control conditions and dietary restraint groups. However, a moderated regression showed that attentional bias toward food or self-control images predicted eating behavior only in participants who previously exerted self-control, while no effect was found for parti…

Bayesian analysis of multimethod ego-depletion studies favours the null hypothesis.
Ego-depletion refers to the purported decrease in performance on a task requiring self-control after engaging in a previous task involving self-control, with self-control proposed to be a limited resource. Despite many published studies consistent with this hypothesis, recurrent null findings within our laboratory and indications of publication bias have called into question the validity of the depletion effect. This project used three depletion protocols involved three different depleting initial tasks followed by three different self-control tasks as dependent measures (total n = 840). For each method, effect sizes were not significantly different from zero When data were aggregated across the three different methods and examined meta-analytically, the pooled effect size was not significantly different from zero (for all priors evaluated, Hedges' g = 0.10 with 95% credibility interval …

Exogenous Testosterone Rapidly Increases Aggressive Behavior in Dominant and Impulsive Men.
Background: Although traditional wisdom suggests that baseline levels of testosterone (T) promote aggressive behavior, decades of research have produced findings that have been largely weak and inconsistent. However, more recent experimental work suggests that exogenous administration of T rapidly potentiates amygdala and hypothalamus responses to angry facial expressions. Notably, these brain regions are rich in androgen receptors and play a key role in modulating aggressive behavior in animal models.
Methods: The present experiment extends this work by examining whether acutely increasing T potentiates aggressive behavior in men. In a double-blind, placebo-controlled, between-subject design, healthy adult men (n = 121) were administered either T or placebo, and subsequently engaged in a well-validated decision-making game that measures aggressive behavior in response to social provocat…

Too Depleted to Try? Testing the Process Model of Ego Depletion in the Context of Unhealthy Snack Consumption.
Background: The process model proposes that the ego depletion effect is due to (a) an increase in motivation toward indulgence, and (b) a decrease in motivation to control behaviour following an initial act of self-control. In contrast, the reflective-impulsive model predicts that ego depletion results in behaviour that is more consistent with desires, and less consistent with motivations, rather than influencing the strength of desires and motivations. The current study sought to test these alternative accounts of the relationships between ego depletion, motivation, desire, and self-control.
Methods: One hundred and fifty-six undergraduate women were randomised to complete a depleting e-crossing task or a non-depleting task, followed by a lab-based measure of snack intake, and self-report measures of motivation and desire strength.
Results and conclusions: In partial support of the proc…

Dietary self-control is related to the speed with which attributes of healthfulness and tastiness are processed.
We propose that self-control failures, and variation across individuals in self-control abilities, are partly due to differences in the speed with which the decision-making circuitry processes basic attributes, such as tastiness, versus more abstract attributes, such as healthfulness. We tested these hypotheses by combining a dietary-choice task with a novel form of mouse tracking that allowed us to pinpoint when different attributes were being integrated into the choice process with temporal resolution at the millisecond level. We found that, on average, tastiness was processed about 195 ms earlier than healthfulness during the choice process. We also found that 13% to 39% of observed individual differences in self-control ability could be explained by differences in the relative speed with which tastiness and healthfulness were processed.

Beneficial effect of napping on mood and cognitive performance in adolescent athletes.
Adolescent athletes often experience chronic sleep deprivation, impairing mood, cognitive and athletic performance. While napping benefits adults, its effects in adolescent athletes remain unclear. We examined whether a 60-min nap (NAP) improves mood, attention, and declarative learning in 12 male adolescent basketball players. They completed two randomized and counterbalanced conditions: NAP and control rest. Mood and subjective sleepiness were assessed in pre- and post-conditions and objective attention was measured after both conditions. Declarative learning was evaluated using word-pair task at baseline and after 4, 8, and 72 h. Objective sleep quality and quantity were measured via actigraphy. Napping enhanced attention (p = 0.006, d = 0.98, Δ=+14.55%) and improved declarative learning at 4 h (p = 0.003, d = 1.09, Δ=+8.40%) and 72 h (p = 0.021, d = 0.78, Δ=+8.95%) retest. Mood param…

The effects of a personalized sleep improvement app in subclinical poor sleepers: A randomized controlled trial.
The aim of this study was to determine the effects of a personalized smartphone application on subjective sleep quality, wellbeing and stress in participants with subclinical sleep problems. Healthy participants with subclinical threshold sleep issues that did not meet diagnostic criteria for insomnia were randomly assigned to use the app or be on a waiting list for app usage (control group). Subjective data on sleep quality (sleep quality component of Sleep Questionnaire B [primary endpoint] and the Pittsburgh Sleep Quality Index), feeling refreshed after the sleep component of Sleep Questionnaire B, Short Form-12 physical and mental components, and stress (Perceived Stress Scale) were compared between the app and control groups at baseline and after 6 and 12 weeks. Depending on their usage, app users were defined as "frequent", "occasional" or "rare/never" users. Two-hundred and six an…

Investigating the subjective and objective efficacy of a cognitive behavioural therapy for insomnia (CBT-I)-based smartphone app on sleep: A randomised controlled trial.
Due to insufficient treatment options for insomnia, effective solutions are urgently needed. We evaluated the effects of a CBT-I-based app combining sleep training with subjective and objective sleep monitoring on (i) sleep and (ii) subjective-objective sleep discrepancies (SOSD). Fifty-seven volunteers (20-76 years; MAge = 45.67 ± 16.38; 39 female) suffering from sleep problems were randomly assigned to an experimental group (EG, n = 28) or a waitlist control group (CG, n = 29). During the 6-week app phase, the EG used the CBT-I-based programme and a heart rate sensor for daily sleep monitoring and -feedback, while the CG used sleep monitoring only. Sleep was measured (i) subjectively via questionnaires (Insomnia Severity Index, ISI; Pittsburgh Sleep Quality Index, PSQI), (ii) objectively via ambulatory polysomnography (PSG), and (iii) continuously via heart-rate sensor and sleep diarie…

Sleep disturbances are present in ~65% of individuals with generalised anxiety disorder (GAD). Although both Kundalini yoga (KY) and cognitive behavioural therapy (CBT) are effective treatment options for GAD, little is known about how these treatments compare in improving sleep for GAD and what drives these changes. Accordingly, we examined the effects of CBT, KY, and stress education (SEdu; an attention control condition) on subjective sleep quality (as measured by the Pittsburgh Sleep Quality Index [PSQI] and Insomnia Severity Index [ISI]) in a randomised controlled trial of 226 adults with GAD (mean age 33.37 years; 70% female; 79% White). We hypothesised that both CBT and KY would outperform SEdu in improving sleep disturbances. Three potential mediators of sleep improvement (worry, mindfulness, perceived stress) were also examined. In line with hypotheses, PSQI and ISI scores signi…

The translation and validation of the procrastination and precrastination traits scale in the modern Arabic Language.
Procrastination and precrastination are distinct self-regulatory behaviors that influence individual functioning and well-being. Despite growing interest in these constructs, culturally adapted and psychometrically validated tools in Arabic-speaking contexts remain limited. This study addresses this gap by translating, validating, and evaluating the psychometric properties of the Arabic version of the Procrastination and Precrastination Traits Scale (PPTS). The present study aimed to examine the factorial structure, reliability, and convergent and divergent validity of the Arabic PPTS among Arabic-speaking adults and explore its associations with life satisfaction and standardized measures of procrastination. A sample of 1,000 participants (mean age = 27.93 years, standard deviation (SD) = 5.73; age range = 18-38) completed an online survey comprising the 18-item PPTS, the 12-item Pure P…

Academic procrastination has been seen as an impediment to students' academic success. Research findings suggest that it is related to lower levels of self-regulated learning and academic self-efficacy and associated with higher levels of anxiety, stress, and illness. Emotional intelligence (EI) is the ability to assess, regulate, and utilize emotions and has been found to be associated with academic self-efficacy and a variety of better outcomes, including academic performance. Students with learning disabilities (LD) are well acquainted with academic difficulty and maladaptive academic behavior. In comparison to students without LD, they exhibit high levels of learned helplessness, including diminished persistence, lower academic expectations, and negative affect. This study examined the relationships among academic procrastination, EI, and academic performance as mediated by academic …

Effects of smartphone addiction on sleep quality among Chinese university students: The mediating role of self-regulation and bedtime procrastination.
The steep rise of smartphone use has raised public concerns about smartphone addiction and its associated negative health consequences, such as poor sleep quality; however, limited research has examined the psychological mechanisms underlying these associations. The current study tested the effects of smartphone addiction on poor sleep quality, through self-regulation and bedtime procrastination, among 427 Chinese undergraduate students, aged 18 or older (M = 19.36; female = 66%), who voluntarily completed an anonymous online questionnaire. The results showed that 1/3 of participants reported poor subjective sleep quality. Smartphone addiction and bedtime procrastination had a significant positive relationship, whereas self-regulation had a significant negative association, with poor sleep quality (which was assessed by sleep latency, sleep duration, and subjective sleep quality). Despit…
