Free flowing thought in bilinguals and monolinguals: How language experience and lexical properties influence word associations

Language shapes the organization of semantic memory and influences how individuals retrieve and combine concepts. The present study examined how language experience relates to associative thinking using Forward Flow, a metric that captures how far a thought sequence diverges semantically from an initial concept. Spanish-English bilinguals and English monolinguals completed a free association task in each of their respective languages. Greater vocabulary and language dominance predicted higher Forward Flow, indicating more semantically distant thought sequences. Among bilinguals, Forward Flow was higher in the dominant language than in the non-dominant language, suggesting that the conceptual associations bilinguals make depend on the language of retrieval. The associations participants generated were also influenced by idiosyncratic features of the languages they spoke, such as compounding, semantic ambiguity, and phonology. Our findings suggest that individual language experience and language-specific properties are linked to associative thinking, highlighting the role of language in the conceptual associations people make.
