| Abstract: | SNARC effect is called the joint effect of spatial digital response coding, which is the proof of the connection between number and space. There are mainly theoretical explanations, such as the mental number line explanation of long-term memory, the working memory explanation of short-term memory, and the dual path pattern explanation. Recent studies have demonstrated that SNARC effect is the online construction of digits in working memory during task execution, and the online construction of digits SNARC effect is interfered by letter processing in the mixed situation of digits and letters, which further supports the hypothesis of working memory. Although online encoding of SNARC effect has been proved, it is not clear whether online encoding of digital spatial representation in the mixed alphanumeric context has automaticity, and if so, whether it will be interfered by letter processing. In this study, three digit color judgment experiments were conducted, and the ratio of digits to letters was 1:1. 1:6. The paper explores whether the online construction of digital space representation is automaticity in the mixed interference situation of 6:1. To investigate the interference of letter processing on digital SNARC effect, explore whether the interference is regulated by the proportion of number letters, and further explore the automatic mechanism of the interference of letter processing on digital space coding. The results showed that SNARC effect was not observed in the mixed numbers and letters at different proportions. It shows that the online construction of digital space representation in the mixed alphanumeric situation does not have automaticity. When the task does not directly activate the size order information of the number letters, the letters will interfere with the online construction of the number SNARC effect, which is not proportional adjustment. |
