手势图片的SNARC效应

摘要

By use of the experimental paradigm proposed by Dehaene,the research subj ects were asked to classify the numbers shown and the numbers symbolized by hand gestures so as to explore the differences between the SNARC effect of hand gestures and the SNARC effect of numbers.The results indicated that:(1)There exists SNARC effect in the processing of finger counting pictures,which further indicates that the SNARC effect has great stability and universality;(2)the process-ing of hand gestures is much more difficult and complex than that of the Arabic numbers,yet the SNARC effect is found in the processing of the two materials,whose results prove to be consistent with the computational model for digital processing pro-posed by Vergut et al.%采用Dehaene等人的实验范式，要求被试对呈现的数字或手势图片代表的数字快速分类。探讨了手势图片的 SNARC效应及其与数字 SNARC效应的差异。结果发现：(1)手势图片的加工中存在 SNARC效应，进一步说明SNARC效应具有很大的稳定性和普遍性。(2)手势图片比阿拉伯数字的加工难度更大、过程更复杂，但在两种材料的加工中都出现 SNARC效应，结果支持了 Vergut等人数字加工的计算模型。
