abstract = {Iconicity is the property whereby signs (vocal or manual) resemble their referents. Iconic signs are easy to relate
to the world, facilitating learning and processing. In this study, we examined whether the benefits of iconicity
would lead to its emergence and to maintenance in language. We focused on shape iconicity (the association
between rounded objects and round-sounding words like “bouba” and between spiky objects and spiky-sound-
ing words like “kiki”) and motion iconicity (the association between longer words and longer events). In
Experiment 1, participants generated novel labels for round versus spiky shapes and long versus short move-
ments (Experiment 1a: text, Experiment 1b: speech). Labels for each kind of stimulus differed in a way that
was consistent with previous studies of iconicity. This suggests that iconicity emerges even on a completely
unconstrainted task. In Experiment 2 (Experiment 2a: text, Experiment 2b: speech), we simulated language
change in the laboratory (as iterated learning) and found that both forms of iconicity were introduced and main-
tained through generations of language users. Thus, we demonstrate the emergence of iconicity in spoken lan-
guages, and we argue that these results reflect a pressure for language systems to be referential, which favors
iconic forms in the cultural evolution of language (at least up to a point where it is balanced by other pressures,
e.g., discriminability). This can explain why we have iconicity across natural languages and may have implica-
tions for debates on language origins.},
