在包括空间、数量和时间在内的多个维度上表示幅度信息是人脑的一项重要功能。许多先前的研究报告说，数字和空间的大小可以通过一条“心理数字线”相互影响。在这项研究中，我们讨论了非时间维度的大小和时间的大小是否独立表示的问题。观察者判断刺激的持续时间，而四种类型的非时间性大小信息，包括点的数量、开放正方形的大小、实心正方形的亮度和数字的数值，在Stroop样范式中被操纵。结果显示，在这些非时间维度上，幅度越大的刺激被判断为时间上越长。这一观察结果支持时间维度和非时间维度上的震级不是独立的这一观点，并暗示在震级表示中存在广义和抽象成分。
Representing magnitude information in various dimensions, including space, quantity, and time, is an important function of the human brain. Many previous studies reported that numerical and spatial magnitudes could be mutually influenced through a "mental number line". In this study, we address the question of whether magnitudes in nontemporal dimensions and magnitudes in time are represented independently or not. Observers judged the duration of the stimuli while four types of nontemporal magnitude information, including number of dots, size of open squares, luminance of solid squares, and numeric value of digits, were manipulated in Stroop-like paradigms. Results revealed that stimuli with larger magnitudes in these nontemporal dimensions were judged to be temporally longer. This observation supports the idea that magnitudes in temporal and nontemporal dimensions are not independent and implies the existence of generalized and abstract components in the magnitude representations.
