空间注意是探索和处理周围环境的关键因素，在连接空间、时间和数字等大小方面发挥着作用。本研究评估了通过旋转头部运动改变空间注意坐标是否会影响估计不同时间间隔的持续时间的能力。采用基于计算机的内隐计时任务，参与者被要求集中注意力并口头报告计算机屏幕上显示的连续刺激的颜色变化；随后，他们被要求再现时间持续时间(范围在5秒到80秒之间)。使用计算机键盘对感知到的刺激进行识别。在统计上，80秒的时间被高估了。间隔时间仅限于向右旋转的头部姿势，而头部姿势在较短的间隔时间内不影响计时成绩。这些发现支持这样一种假设，即空间注意的坐标影响处理时间的能力，这与健康人类存在共同的空间和时间皮质度量一致。
Spatial attention is a key factor in the exploration and processing of the surrounding environment, and plays a role in linking magnitudes such as space, time, and numbers. The present work evaluates whether shifting the coordinates of spatial attention through rotational head movements may affect the ability to estimate the duration of different time intervals. A computer-based implicit timing task was employed, in which participants were asked to concentrate and report verbally on colour changes of sequential stimuli displayed on a computer screen; subsequently, they were required to reproduce the temporal duration (ranging between 5 and 80 sec.) of the perceived stimuli using the computer keyboard. There was statistically significant overestimation of the 80-sec. intervals exclusively on the rightward rotation head posture, whereas head posture did not affect timing performances on shorter intervals. These findings support the hypothesis that the coordinates of spatial attention influence the ability to process time, consistent with the existence of common cortical metrics of space and time in healthy humans.
