2026-05-06 Dataset for the paper “Shared Neurogenetic Substrates of Non-planning Impulsivity and Procrastination” doi:10.57760/sciencedb.psych.00846 en Procrastination has maladaptive impact on health and survival, yet it remains moderately heritable, presenting a biological paradox. Procrastination has been conceptualized as a byproduct of impulsivity, explaining its prevalence despite no discernible adaptive benefit. However, the shared neurobiological substrates underlying the association between impulsivity and procrastination have yet to be elucidated. Using a longitudinal twin cohort (N = 154), we show that non-planning impulsivity (NPI) during late adolescence and early adulthood is prospectively associated with procrastination in later life. This effect was independently replicated in two cross-sectional cohorts (N = 327; N = 1,543). Twin modeling using an additive genetic and non-shared environmental (AE) framework, together with a meta-analysis of twin studies (N = 3,656 twin pairs) revealed significant shared genetic contributions (rg = 0.51). Beyond genetic overlap, neuroimaging meta-analysis (NeuroSynth meta‑analysis for impulsivity: k = 198 studies, 5855 loci; mini meta-analysis for procrastination: k = 5 studies, 7 independent samples, Ncumulative = 893 participants), normative modeling (N = 37,407), and seed-based d mapping (SDM) converged on the left dorsolateral prefrontal cortex (DLPFC) as the region of maximal overlap between NPI and procrastination. The transcriptional profiles of the left DLPFC and impulsivity-associated genes exhibited functional convergence on regulation of biological and cellular processes. These genes showed brain-specific expression and associations with cortical metabolism, neurodegenerative disease, and developmental expression peaks, indicating a shared molecular basis for the neurogenetic architecture of procrastination. Together, our findings delineate a cross-scale characterization of the shared neurogenetic substrates linking NPI and procrastination, offering empirical evidence that elucidates the biological origins of procrastination.This dataset includes the de-identified summary data and analysis scripts for the paper “Shared Neurogenetic Substrates of Non-planning Impulsivity and Procrastination” compiled in the order in which the results are presented. procrastination; non-planning impulsivity; twin studies; dorsolateral prefrontal cortex; behavioral genetics Yuanyuan Hu Jie Xiang Yuening Jin Qingchen Fan Changshuo Wang Yihan Wu Dang Zheng Yancheng Tang Wei Li Bowen Hu Tingyong Feng Yuan Zhou Zhiyi Chen RESTRICTED dataset Science Data Bank
