从跨通道的角度入手,采用大小比较任务,对视听单通道及跨通道下数量空间表征的特点及表征过程中的相互影响进行探讨。结果发现,视觉通道和听觉通道均存在SNARC效应;在跨通道任务下,无论启动通道是视觉还是听觉通道,都表现出,当启动通道的数量大小信息与主通道的数量大小一致或无关时,主通道的SNARC效应没有显著变化;但当启动通道的数量大小信息与主通道不一致时,主通道的SNARC效应受到显著影响,表现为降低或消失。这进一步证明了SNARC效应受情境影响的特点,并发现在进行跨通道数量空间表征时,听觉通道的数量信息对视觉通道下的数量空间表征的影响大于视觉通道的数量信息对听觉通道下的数量空间表征的影响。
From the perspective of cross-corridor, the size-comparison task is used to discuss the characteristics of quantitative space under cross-corridor and cross-corridor and the mutual influence during characterization. The results show that there are SNARC effects in both visual and auditory channels. Under the cross-channel task, no matter whether the starting channel is a visual or auditory channel, it shows that when the quantity of the initiating channel is the same or not related to the number of main channels, The SNARC effect of the main channel does not change significantly. However, when the information of the start channel is inconsistent with that of the main channel, the SNARC effect of the main channel is significantly affected and appears to decrease or disappear. This further proves that the SNARC effect is affected by the situation and finds that the quantity information of the auditory pathway affects the quantitative and spatial characterization of the visual pathway more than the number of the visual pathway when performing cross-channel quantitative space characterization. Impact of characterization.
