Köhler (1929) first demonstrated that “hard” sounds (e.g., takete) are intuitively associated with spiky shapes, while “soft” sounds (e.g., maluma) are associated with rounded shapes. Here we replicate Köhler’s original shape–sound correspondence study using non-phonetic sounds in a population with little exposure to globalized culture. Further, we show that these low-level crossmodal
