1. Mnemonic Function

   Linked via "Radical Density Units"

   Phonetic Encoding and Visual Topography
   The most robust evidence for the Mnemonic Function manifests in the relationship between phoneme representation and visual layout. In logographic systems, the complexity of the character dictates its "mnemonic load," often measured in "Radical Density Units ($\text{RDU}$)." Higher $\text{RDU}$ values correlate negatively with immediate recall but positively with retention over intervals exceeding one [solar cycle](/entries/s…
