Building on previous findings of prosody perception difficulties and their impact on language development, we aim to describe the Mismatch Responses (MMR) of both groups when perceiving the unique three-way quantity distinction of Estonian prosody. This study is longitudinal with two measurement points. Here, we present the findings from the second measurement and compare them to those from the first. Our methodology involves compreheensive psychometric testing and complete EEG examinations for the DLD group, alongside a passive oddball paradigm with various stimuli. We also explore potential correlations between neurophysiological and behavioral results and investigate the influence of environmental factors.

Mapping boundaries: Microprosodic and dialectal variability in the perception of Estonian long and overlong quantity. – Eesti Rakenduslingvistika Ühingu aastaraamat = Estonian Papers in Applied Linguistics 21. This paper presents the results of a web-based perception experiment that tested the distinction of long (Q2) and overlong (Q2) quantity degrees in Estonian. Firstly, we observe segmental quality effect on the quantity perception. The stimuli were created from words with 8 different segmental combinations. The second aim of this study is to map the dialectal variability in Estonian quantity perception. There has been some evidence that the listeners from East and South dialect areas are less sensitive to pitch cue than those from North and West. The current study was carried out with 290 participants with various regional background. The results showed that different segmental quality sets have slightly different Q2–Q3 category boundaries. Also, the precision of quantity identification was considerably lower in the case of nonsense word set. Unexpectedly, we were not able to find a clear dialectal background effect.

Native speakers of Chinese (N=44) and Estonian (N=46), each group subdivided into musicians and non-musicians, participated in a mismatch negativity (MMN) experiment where they passively listened to both Chinese and Estonian stimuli, followed by a behavioral experiment where they attentively discriminated the stimuli in the non-native language (i.e., Chinese to Estonian participants and Estonian to Chinese participants). In both experiments, stimuli of duration change, pitch change, and duration plus pitch change were discriminated. We found higher behavioral sensitivity among Chinese musicians than non-musicians in perceiving the duration change in Estonian and higher behavioral sensitivity among Estonian musicians than non-musicians in perceiving all types of changes in Chinese, but no corresponding effect was found in the MMN results, which suggests a more salient effect of musical expertise on foreign language processing when attention is required. Secondly, Chinese musicians did not outperform non-musicians in attentively discriminating the pitch-related stimuli in Estonian, suggesting that musical expertise can be overridden by tonal language experience when perceiving foreign linguistic pitch, especially when an attentive discrimination task is administered. Thirdly, we found larger MMN among Chinese and Estonian musicians than their non-musician counterparts in perceiving the largest deviant (i.e., duration plus pitch) in their native language. Taken together, our results demonstrate a positive effect of musical expertise on language processing.
