Round is sweet.. but angular is…

Chuquichambi and colleagues report that “People generally associate curved and symmetrical shapes with sweetness, while associating angular and asymmetrical shapes with the other basic tastes (e.g., sour, bitter). . . . The results replicate the general . . . correspondences between curved-sweet and symmetrical-sweet stimuli. Furthermore, participants tended to match sour and bitter tastes with angular and asymmetrical stimuli. . . . Liking for curved and symmetrical stimuli was higher than for angular and asymmetrical stimuli.”
