Numerous studies suggest that speakers of some tone languages show advantages in musical pitch processing compared to non-tone language speakers. A recent study in adults (Jasmin et al., 2021) suggests that in addition to heightened pitch sensitivity, tone language speakers weight pitch information more strongly than other auditory cues (amplitude, duration) in both linguistic and nonlinguistic settings compared to non-tone language speakers. The current study asks whether pitch upweighting is evident in early childhood. To test this, two groups of 3- to 5-year-old children—tone-language speakers (n = 48), a group previously shown to have a perceptual advantage in musical pitch tasks (Creel et al., 2018), and non-tone-language speakers (n = 48)—took part in a musical “word learning” task. Children associated two cartoon characters with two brief musical phrases differing in both musical instrument and contour. If tone language speakers weight pitch more strongly, cue conflict trials should show stronger pitch responding than for non-tone speakers. In contrast to both adult speakers’ stronger pitch weighting and child and adult pitch perception advantages, tone-language-speaking children did not show greater weighting of pitch information than non-tone-language speaking children. This suggests a slow developmental course for pitch reweighting, contrasting with apparent early emergence of pitch sensitivity.
