The spontaneous extraction and utilization of relational structures across different domains, as demonstrated in the study, aligns with broader theories of human intelligence and cognitive flexibility. The ability to identify and leverage common structures to organize information reflects cognitive flexibility, which is essential for adapting to new situations and solving complex problems. This process of integrating information from diverse domains into a coherent framework is a hallmark of higher-order cognitive processes associated with human intelligence. The findings suggest that individuals can flexibly apply common structures to facilitate memory storage and retrieval, highlighting the adaptive nature of cognitive processes. This ability to extract and utilize relational structures across domains may underlie the capacity for abstract thinking, problem-solving, and creative reasoning, all of which are key components of human intelligence. Overall, the study's results support the idea that cognitive flexibility and intelligence are closely linked to the efficient organization of information based on shared structures.
