Prominence effects in vocal iconicity: Implications for lexical access and language changea).

This paper explores how three cognitive and perceptual cues, vocal iconicity, resemblance-based mappings between form and meaning, and segment position and lexical stress, interact to affect word formation and language processing. The study combines an analysis of the word-internal positions that iconic segments occur in based on data from 245 language families with an experimental study in which participants representing more than 30 languages rated iconic and non-iconic pseudowords. The pseudowords were designed to systematically vary segment and stress placement across syllables. The results for study 1 indicate that segments used iconically appear approximately 0.26 segment positions closer toward the beginning of words compared to non-iconic segments. In study 2, it was found that iconic segments occurring in stressed syllables and non-iconic segments occurring in the second syllable were rated as significantly more fitting. These findings suggest that the interplay between vocal iconicity and prominence effects increases the predictive function of iconic segments by foregrounding sounds, which intrinsically carry semantic information. Consequently, these results contribute to the understanding of the widespread occurrence of vocal iconicity in human languages.
