先前的研究表明，拖延症的个体差异与日常目标管理能力有关，但很少有研究针对可能构成拖延症倾向的特定认知能力，如执行功能（EFs）。在本研究中，我们运用行为遗传学方法探讨了拖延症与EF能力之间关系的两种假设：(a)拖延症与一般EF能力呈负相关，(b)这种关系是由于拖延症的遗传成分与其他日常目标管理能力最相关。结果证实了这两个假设。拖延症在表型和遗传水平上都与较差的一般EF能力有关，这种关系是由于拖延症的成分与日常目标管理失败的自我报告测量共享。即使在控制了潜在的自我报告偏差后，这些结果仍然被观察到，这些偏差源于以社会期望的方式做出反应的冲动。总之，这些发现为不断发展的拖延症理论提供了强有力的证据，这些理论强调了与目标相关的认知能力的重要性，并进一步强调了拖延症背后重要的遗传影响。
Previous research has suggested that individual differences in procrastination are tied to everyday goal-management abilities, but little research has been conducted on specific cognitive abilities that may underlie tendencies for procrastination, such as executive functions (EFs). In this study, we used behavioral genetics methodology to investigate two hypotheses about the relationships between procrastination and EF ability: (a) that procrastination is negatively correlated with general EF ability, and (b) that this relationship is due to the genetic components of procrastination that are most related to other everyday goal-management abilities. The results confirmed both of these hypotheses. Procrastination was related to worse general EF ability at both the phenotypic and genetic levels, and this relationship was due to the component of procrastination shared with self-report measures of everyday goal-management failures. These results were observed even after controlling for potential self-report biases stemming from the urge to respond in a socially desirable manner. Together, these findings provide strong evidence for growing theories of procrastination emphasizing the importance of goal-related cognitive abilities and further highlight important genetic influences that underlie procrastination.
