The vmPFC-IPL functional connectivity as the neural basis of future self-continuity impacted procrastination: the mediating role of anticipated positive outcomes

Procrastination is universally acknowledged as a problematic behavior with wide-ranging consequences impacting various facets of individuals' lives, including academic achievement, social accomplishments, and mental health. Although previous research has indicated that future self-continuity is robustly negatively correlated with procrastination, it remains unknown about the neural mechanisms underlying the impact of future self-continuity on procrastination. To address this issue, we employed a free construction approach to collect individuals' episodic future thinking (EFT) thoughts regarding specific procrastination tasks. Next, we conducted voxel-based morphometry (VBM) and resting-state functional connectivity (RSFC) analysis to explore the neural substrates underlying future self-continuity. Behavior results revealed that future self-continuity was significantly negatively correlated with procrastination, and positively correlated with anticipated positive outcome. The VBM analysis showed a positive association between future self-continuity and gray matter volumes in the right ventromedial prefrontal cortex (vmPFC). Furthermore, the RSFC results indicated that the functional connectivity between the right vmPFC and the left inferior parietal lobule (IPL) was positively correlated with future self-continuity. More importantly, the mediation analysis demonstrated that anticipated positive outcome can completely mediate the relationship between the vmPFC-IPL functional connectivity and procrastination. These findings suggested that vmPFC-IPL functional connectivity might prompt anticipated positive outcome about the task and thereby reduce procrastination, which provides a new perspective to understand the relationship between future self-continuity and procrastination.

The triple psychological and neural bases underlying procrastination: Evidence based on a two-year longitudinal study

The triple brain anatomical network model of procrastination theorized procrastination as the result of psychological and neural dysfunction implicated in self-control, emotion regulation and episodic prospection. However, no studies have provided empirical evidence for such model. To address this issue, we designed a two-wave longitudinal study where participants underwent the resting-state scanning and completed the questionnaires at two time-points that spanned 2-year apart (T1, n = 457; T2, n = 457). Using the cross-lagged panel network modeling (CLPN), we found that triple psychological components at T1, including self-control, emotion regulation (i.e., reappraisal) and episodic prospection, negatively predicted procrastination at T2 in the temporal network. Moreover, the CLPN modeling found that functional connectivity between networks accounting for episodic prospection (EP) and emotion regulation (ER) positively predicted future procrastination in the temporal network. The centrality analyzes further showed that procrastination was greatly affected by other nodes, whilst the psychological component (i.e., episodic prospection), and the functional network connectivity (FNC) of EP- ER exerted strongest impacts on other nodes in the networks, which indicated that treatments targeting episodic prospection might largely help reduce procrastination. Collectively, these findings firstly provide evidence for testifying the triple brain anatomical network model of procrastination, and highlights the contribution of triple psychological and neural components implicated in self-control, emotion regulation and episodic prospection to procrastination that enhances our understanding of causes of procrastination.

The role of personality traits and need for cognition in active procrastination

Recent research has differentiated between active and passive procrastination, with the former considered to be beneficial for learning and the latter considered to be harmful. Studies have shown that both personality and cognitive factors are important in students' active procrastination. This study examines how interactions between the Big Five personality traits and the need for cognition affect students' active procrastination. The hypotheses were tested empirically using cross-sectional data collected from 307 university students in China. After controlling for age, a hierarchical regression analysis revealed that extraversion was a positive predictor of active procrastination, and that agreeableness and emotional instability were negative predictors of active procrastination. No significant interaction effects were found between personality traits and need for cognition. The implications of the findings are discussed.

Self-Handicapping Among University Students: The Role of Procrastination, Test Anxiety, Self-Esteem, and Self-Compassion

The purpose of the present study was to examine the predictor role of procrastination, test anxiety, self-esteem, and self-compassion for the variation in university students' self-handicapping. The sample of the study consisted of 801 undergraduate students (404 females and 397 males). In order to collect data, Self-Handicapping Scale, Tuckman Procrastination Scale, Anxiety Subscale of Academic Emotions Questionnaire, Rosenberg Self-Esteem Scale, and Self-Compassion Scale were used. Stepwise regression analysis was conducted, and results showed that all of the predictor variables significantly contributed in explaining self-handicapping. The model explained the 59% of the variance in self-handicapping, whereas semi-partial variance of procrastination, test anxiety, self-esteem, and self-compassion were 17%, 4%, 2%, and 2%, respectively.
