在这项纵向研究中，学龄前儿童在延迟满足任务中将注意力从奖励刺激上转移的时间比例与10年后在进行/不进行任务中响应目标的效率（更快的速度而不降低准确性）呈正相关。总体研究结果表明，学龄前儿童在延迟满足任务中有效地将注意力从奖励的诱人方面转移开的能力可能是多年后执行抑制任务（如go/no-go任务）的能力的发展前兆。由于性能上的去/不去的任务先前已被表征为涉及激活的额纹状体区域，目前的研究结果还表明，在延迟满足任务的性能可能作为一个早期标记的个体差异的功能完整性，这个电路。
In this longitudinal study, the proportion of time preschoolers directed their attention away from rewarding stimuli during a delay-of-gratification task was positively associated with efficiency (greater speed without reduced accuracy) at responding to targets in a go/no-go task more than 10 years later. The overall findings suggest that preschoolers' ability to effectively direct their attention away from tempting aspects of the rewards in a delay-of-gratification task may be a developmental precursor for the ability to perform inhibitory tasks such as the go/no-go task years later. Because performance on the go/no-go task has previously been characterized as involving activation of fronto-striatal regions, the present findings also suggest that performance in the delay-of-gratification task may serve as an early marker of individual differences in the functional integrity of this circuitry.
