ERP research on the characteristics of icon memory will be an important reference standard in guiding user neurocognitive behavior and physiology assessment on interface usability.展开更多

The study of iconicity has great significance of revealing the relationship between concept and cognition and can help people better understand the essence of language. This paper presents an analysis of the three iconicity principles- distance iconicity,quantity iconicity and sequencing iconicity-base on the relevance theory. The purpose of this pa?per is to offer a new dimension to iconicity analysis and finding more connections between the form of language and real mean?ing.展开更多
