Shapes and Sounds, Link Confirmed (09-02-20)

A research team lead by Aryani confirms that humans link particular shapes and sounds.  Aryani and colleagues report that “Prior investigations have demonstrated that people tend to link pseudowords such as bouba to rounded shapes and kiki to spiky shapes, but the cognitive processes underlying this matching bias have remained controversial. . . .  we found that kiki-like pseudowords and spiky shapes, compared with bouba-like pseudowords and rounded shapes, consistently elicit higher levels of affective [emotional] arousal.”
