请将以下 lexical attraction 的定义总结为三句话以内的内容：“Lexical attraction, in linguistics, is a phenomenon where words of similar or related meanings or sounds are strongly inclined to occur in proximity to each other within a sentence or discourse, often more than mere chance would suggest. This tendency can be attributed to cognitive and linguistic factors, such as the way the brain processes and stores related information, and the influence of longstanding linguistic conventions. Understanding lexical attraction can provide insights into the structure of language, the mental lexicon, and the psychological processes that underpin language use and comprehension.”

词汇吸引力是在语言学中指相似或相关意义或发音的词语倾向于在一个句子或话语中彼此邻近出现的现象。这种倾向可能源于认知和语言因素，如大脑处理和存储相关信息的方式，以及长期的语言习惯影响。研究词汇吸引力有助于理解语言结构、心理词汇及其在语言使用和理解中的心理过程。
