A previous study used days as a sequence symbol to investigate the interaction mechanism between location and sequence in sequence symbol cognition; the study findings suggested that the spatial stimulus-response compatibility effect and the Simon effect could not co-exist with the SNARC-like effect when processing sequence symbols. The previous study did not include the influence of the difficulty of identifying sequence symbols on the Simon effect in the investigation, so it is unclear whether the conclusion about processing sequence symbols with considerable identification difficulty can be extended to the processing of sequence symbols with less identification difficulty. Therefore, the present study explored letters that have a low level of identification difficulty to investigate the interaction mechanism between location and sequence in sequence symbol cognition. Participants were asked to classify a probe letter, which was randomly displayed on the left or right side of the screen, according to its location (Experiment 1), its sequence (Experiment 2) or its colour (Experiment 3). The results indicated that (1) only the spatial stimulus-response compatibility effect and Simon effect were present in the letter location classification task and letter colour classification task, respectively. (2) The Simon effect co-existed with the SNARC-like effect, and these two effects interacted with each other in the letter sequence classification task. From these results, it can be concluded that the task determines whether the Simon effect and the SNARC-like effect can co-exist, with differences presented across sequence symbols.
先前的研究使用天数作为序列符号来探究序列符号认知中位置和序列之间的交互机制；研究结果表明，在处理序列符号时，空间刺激-反应相容性效应和 Simon 效应不能与 SNARC 样效应同时存在。先前的研究没有调查识别序列符号的难度对 Simon 效应的影响，因此，处理具有相当难度的序列符号的结论是否可以扩展到处理识别难度较低的序列符号尚不清楚。因此，本研究使用具有较低识别难度的字母来探究序列符号认知中位置和序列之间的交互机制。要求参与者根据字母的位置（实验 1）、序列（实验 2）或颜色（实验 3）对随机显示在屏幕左侧或右侧的探测字母进行分类。结果表明：（1）仅在字母位置分类任务和字母颜色分类任务中存在空间刺激-反应相容性效应和 Simon 效应。（2）在字母序列分类任务中，Simon 效应与 SNARC 样效应共存，这两种效应相互作用。从这些结果可以得出结论，任务决定了 Simon 效应和 SNARC 样效应是否可以共存，并且在序列符号之间存在差异。
