在两次年度评估中，使用教师、测试者和观察员的评分来评估任务持久性的变化。参与者包括79对同卵双胞胎和116对同性异卵双胞胎，他们在最初的评估中是在幼儿园或一年级（4.3至7.9岁）。任务坚持性分布广泛，在年龄较大的儿童和女孩中更高。总的来说，随着时间的推移，持久性有适度的增长，个体差异有适度的稳定性。大多数稳定性是由遗传影响造成的，而大多数变化是由非共享环境造成的，包括与观察到的不同母亲温暖支持行为的关联。
Change in task persistence was assessed in two annual assessments using teachers', testers', and observers' ratings. Participants included 79 monozygotic and 116 same-sex dizygotic twin pairs who were in Kindergarten or 1st grade (4.3 to 7.9 years old) at the initial assessment. Task persistence was widely distributed and higher among older children and girls. Overall, there was modest growth in persistence over time, and moderate stability of individual differences. Most of the stability was accounted for by genetic influences, whereas most of the change was accounted for by nonshared environment, including an association with observed differential maternal warm supportive behavior.
