注意力调节我们对时间的主观感知。我们对一件事的持续时间关注得越少，它似乎就持续得越短。在事件相关功能磁共振成像研究中，对时间或颜色刺激属性的注意力进行参数调制。任务表现的线性增长伴随着大脑活动的相应增加。增加对时间的关注选择性地增加了皮质纹状体网络的活动，包括前补充运动区和右额叶盖。增加对颜色的关注选择性地增加了V4区的活动。通过识别那些活动被时间注意力特别调制的区域，我们已经定义了计时行为的核心神经解剖学基础。
Attention modulates our subjective perception of time. The less we attend to an event's duration, the shorter it seems to last. Attention to time or color stimulus attributes was modulated parametrically in an event-related functional magnetic resonance imaging study. Linear increases in task performance were accompanied by corresponding increases in brain activity. Increasing attention to time selectively increased activity in a corticostriatal network, including pre-supplementary motor area and right frontal operculum. Increasing attention to color selectively increased activity in area V4. By identifying areas whose activity was specifically modulated by attention to time, we have defined the core neuroanatomical substrates of timing behavior.
