%X 目的：本研究旨在探讨数字表征的空间位置与心理数字线之间的关系，具体而言，较小(较大)的数字表征的位置和心理数字线靠左(靠右)的位置相符合，探究大小判断符号是否影响心理数字线，SNARC效应是否存在。研究基于心理数字线理论，选取30名在校大学生作为被试进行了2 (反应手：左手和右手) × 2 (相容类型：相容性和不相容性)的被试内实验，并通过方差分析对实验数据进行了统计检验。结果表明：在大小判断符号任务中，小于号相容的不等式判断反应明显快于不相容的不等式；大于号不相容的不等式判断反应反而快于相容的不等式，该结果影响SNARC效应的出现，可能受到大小判断符号任务情境的影响，从而可以体现数字空间表征具有灵活性。
Objective: This study aims to investigate the relationship between the spatial position of numerical representation and the mental number line. Specifically, it examines whether the position of smaller (larger) numbers aligns with the left (right) side of the mental number line, and explores whether the symbol used for magnitude judgment affects the mental number line and whether the SNARC (Spatial-Numerical Association of Response Codes) effect exists. Based on the theory of the mental number line, the study conducted a within-subjects experiment with 30 college students, using a 2 (response hand: left and right) × 2 (compatibility type: compatible and incompatible) design. The experimental data were statistically tested using analysis of variance (ANOVA). The results indicate that in the magnitude judgment task using symbols, responses to inequalities with compatible less-than signs were significantly faster than those with incompatible less-than signs; conversely, responses to inequalities with incompatible greater-than signs were faster than those with compatible greater-than signs. This result influences the emergence of the SNARC effect and may be affected by the context of the size comparison task, thereby demonstrating the flexibility of numerical spatial representation.
