Ideophones in Japanese modulate the P2 and late positive complex responses.

Bottom Line: However, neuroimaging research has mostly focused on artificial non-words or individual segments, which do not represent sound-symbolism in natural language.Our results and previous literature suggest that the larger P2 may indicate the integration of sound and sensory information by association in response to the distinctive phonology of ideophones.This account provides new evidence that ideophones exhibit similar cross-modal correspondences to those which have been proposed for non-words and individual sounds.

ABSTRACT
Sound-symbolism, or the direct link between sound and meaning, is typologically and behaviorally attested across languages. However, neuroimaging research has mostly focused on artificial non-words or individual segments, which do not represent sound-symbolism in natural language. We used EEG to compare Japanese ideophones, which are phonologically distinctive sound-symbolic lexical words, and arbitrary adverbs during a sentence reading task. Ideophones elicit a larger visual P2 response than arbitrary adverbs, as well as a sustained late positive complex. Our results and previous literature suggest that the larger P2 may indicate the integration of sound and sensory information by association in response to the distinctive phonology of ideophones. The late positive complex may reflect the facilitated lexical retrieval of arbitrary words in comparison to ideophones. This account provides new evidence that ideophones exhibit similar cross-modal correspondences to those which have been proposed for non-words and individual sounds.

Figure 2: Event-related potentials and topoplots in response to iconic and arbitrary adverbs.

Mentions: In the N400 analysis, there was a significant difference between ERP amplitudes elicited by iconic and arbitrary conditions across the time window of 350–550 ms (F = 7.566, df = 1,20, p = 0.012, = 0.274). Again, there were no other significant main effects or significant interactions. As the long-lasting increased positivity appeared to begin at around 400 ms and last until the end of the trial, we also tested the time window of 400–800 ms. This too was significant (F = 5.351, df = 1,20, p = 0.031, = 0.211), and there were no significant interactions. The two main effects can be seen in the ERPs and topoplots in Figure 2 and in the ERPs across the four quadrants shown in Figure 3 below.
