Imagine unraveling the intricate tapestry of language, where every word is like a thread that weaves together to form a beautiful structure. In this study, we delved deep into a Japanese lexical database to explore the structure of the lexical environment and how it relates to verbal working memory. Our research was driven by the idea that the way we store and retrieve words in our memory is optimized for efficient communication. We made a fascinating prediction that low-imageable meanings, which are words with abstract concepts, are more frequently associated with phonological patterns in the current vocabulary.
Similar to how a jigsaw puzzle comes together, our findings revealed that less imageable nouns tend to have stronger connections with more common phonological patterns. This phenomenon suggests that the cognitive processes involved in verbal working memory rely on both semantic knowledge and the regularity of phonological patterns. The more robust semantic contributions compensate for the less sturdy phonological representations of infrequent phonological forms.
Our research provides valuable insights into how our brain organizes and stores words, making language processing a symphony of interconnected neural pathways. To delve deeper into this fascinating topic, check out the full article!
Abstract
We analyzed a Japanese lexical database to investigate the structure of the lexical environment based on the hypothesis that the lexical environment is optimized for the functioning of verbal working memory. Our prediction was that, as a consequence of the cultural transmission of language, low-imageable meanings tend to be represented by frequent phonological patterns in the current vocabulary rather than infrequent phonological patterns. This prediction was based on two findings of previous laboratory studies on verbal working memory. (1) The quality of phonological (phonemic and accent) representations in verbal working memory depends on phonological regularity knowledge; therefore, short-term phonological representations are less robust for words with infrequent phonological patterns. (2) Phonological representations are underpinned by contributions from semantic knowledge; therefore, phonological representations of highly imageable words are more robust than those for low-imageable words. Our database analyses show that nouns with less imageable meanings tend to be associated with more frequent phonological patterns in Japanese vocabulary. This lexical structure can maintain the quality of phonological representations in verbal working memory through contributions of semantic and phonological regularity knowledge. Larger semantic contributions compensate for the less robust phonological representations of infrequent phonological forms. The quality of phonological representations is preserved by phonological regularity knowledge when larger semantic contributions are not expected.
