The relation between semantic memory structure, associative abilities, and verbal and figural creativity

Research has independently highlighted the roles of semantic memory and associative abilities in creative thinking. However, it remains unclear how these two capacities relate to each other, nor how they facilitate different creative thinking modalities, such as verbal and figural creativity. This study employed multiple cognitive tests and network science methodologies to shed light on the relationship between them. We constructed individual-based semantic networks and assessed associative abilities, verbal and figural creative thinking. In line with previous studies, we found a relation between verbal creativity and more flexible semantic memory structure (higher connectivity, shorter distances between concepts, and lower modularity). However, we did not find any such relation between figural creativity and semantic memory structure. Associative abilities mediated the relationship between semantic memory structure and verbal creativity, implying the efficient spread of information in semantic memory may facilitate verbal creative thinking via associative abilities. These findings support and extend the associative theory of creativity and shed novel light on the relationship between semantic memory structure, associative abilities, and creativity.
