BACKGROUND: Segments and tone are important sub-syllabic units that play large roles in lexical processing in tonal languages. However, their roles in lexical processing remain unclear, and the event-related potential (ERP) technique will benefit the exploration of the cognitive mechanism in lexical processing.
METHODS: The high temporal resolution of ERP enables the technique to interpret rapidly changing spoken language performances. The present ERP study examined the different roles of segments and tone in Mandarin Chinese lexical processing. An auditory priming experiment was designed that included five types of priming stimuli: consonant mismatch, vowel mismatch, tone mismatch, unrelated mismatch, and identity. Participants were asked to judge whether the target of the prime-target pair was a real Mandarin disyllabic word or not.
RESULTS: Behavioral results including reaction time and response accuracy and ERP results were collected. Results were different from those of previous studies that showed the dominant role of consonants in lexical access in mainly non-tonal languages like English. Our results showed that consonants and vowels play comparable roles, whereas tone plays a less important role than do consonants and vowels in lexical processing in Mandarin.
CONCLUSIONS: These results have implications for understanding the brain mechanisms in lexical processing of tonal languages.

While previous research has found an in-group advantage (IGA) favouring native speakers in emotional prosody perception over non-native speakers, the effects of semantics on emotional prosody perception remain unclear. This study investigated the effects of semantics on emotional prosody perception in Chinese words and sentences for native and non-native Chinese speakers. The critical manipulation was the congruence of prosodic (positive, negative) and semantic (positive, negative, and neutral) valence. Participants listened to a series of audio clips and judged whether the emotional prosody was positive or negative for each utterance. The results revealed an IGA effect: native speakers perceived emotional prosody more accurately and quickly than non-native speakers in Chinese words and sentences. Furthermore, a semantic congruence effect was observed in Chinese words, where both native and non-native speakers recognised emotional prosody more accurately in the semantic-prosody congruent condition than in the incongruent condition. However, in Chinese sentences, this congruence effect was only present for non-native speakers. Additionally, the IGA effect and semantic congruence effect on emotional prosody perception were influenced by prosody valence. These findings illuminate the role of semantics in emotional prosody perception, highlighting perceptual differences between native and non-native Chinese speakers.

The objective of this study was to investigate the impact of music training on the processing of temporal order in Mandarin sentence reading using event-related potentials (ERPs). Two-clause sentences with temporal connectives (\"before\" or \"after\") were presented to both musicians and non-musicians. Additionally, a verbal N-back task was utilized to evaluate the participants\' working memory capacities. The findings revealed that musicians, but not nonmusicians, demonstrated a more negative amplitude in the second clauses of \"before\" sentences compared with \"after\" sentences. In the N-back task, musicians exhibited faster reaction times than nonmusicians in the two-back condition. Furthermore, a correlation was observed between the ERP amplitude differences (before vs. after) and reaction time differences in the N-back task (0-back vs. 2-back) among musicians. These findings suggested that music training enhances the depth of temporal order processing, potentially mediated by improvements in working memory capacity.

Wh-words have been analysed as existential quantifiers (Chierchia in Logic in grammar: polarity, free choice, and intervention. Oxford University Press, Oxford, 2013; Fox, in Sauerland U, Stateva P (eds) Presupposition and implicature in compositional semantics (Palgrave studies in pragmatics, language and cognition). Palgrave MacMillan, Houndmills, pp 71-120, 2007; Liao in Alternative and exhaustification: non-interrogative uses of Chinese wh-words. Harvard University, 2010) or universal quantifiers (Nishigauchi, in: Theoretical and applied linguistics at Kobe Shoin 2, Kobe Shoin Institute for Linguistic Sciences, 1999). These two accounts have distinct predictions on how children initially interpret wh-words. The universal account predicts that children should initially interpret wh-words as universal quantifiers, whereas the existential account anticipates that children should start out with the existential interpretation. To adjudicate between the two accounts, the present study was designed to explore pre-schoolers\' semantic knowledge of wh-quantification. Specifically, it investigated the interpretation of the wh-word shenme \'what\' with 4-and 5-year-old Mandarin-speaking children and a control group of adults. Using a Truth Value Judgment Task (Crain and Thornton in Investigations in universal grammar: a guide to experiments on the acquisition of syntax and semantics. MIT Press, Cambridge, 1998), Experiment 1 evaluated whether children interpret the wh-word shenme \'what\' as closer in meaning to the polarity sensitive item renhe \'any\' or the universal quantifier suoyou \'all\' in the antecedent of ruguo \'if\' conditionals. Using a Question-Answer Task, Experiments 2 & 3 respectively investigated whether children interpret shenme \'what\' as closer in meaning to renhe \'any\' or suoyou \'all\' in two types of questions: yes-no questions with the particle ma and A-not-A questions. It was found that both children and adults interpret shenme \'what\' as closer in meaning to renhe \'any\' than suoyou \'all\'. The findings suggest that Mandarin-speaking pre-schoolers already have adult-like semantic knowledge of wh-quantification: wh-words are existential quantifiers rather than universal quantifiers. Due to the paucity of primary linguistic input, children\'s early mastery of the non-interrogative wh-words appear to support the biolinguistic approach to language acquisition (Chomsky in Aspects of the theory of syntax. MIT Press, Cambridge, 1965; Pinker in Language learnability and language development. Harvard University Press, Cambridge, 1984; Crain et al. in Language acquisition from a biolinguistic perspective. Neurosci Biobehav Rev, 2016. https://doi.org/10.1016/j.neubiorev.2016.09.004 ).

BACKGROUND: Mixed findings have been reported about the computation of scalar or/and ad-hoc implicatures in primarily school-age autistic verbal children and adolescents: while some studies reported their struggles with both implicatures, others observed their strengths in computing scalar implicatures. This study extends the previous investigation by testing the derivation of scalar (including both number and quantifier) and ad-hoc implicatures of a younger group of Mandarin-speaking autistic 4-8-year-olds; moreover, we assess the biological, linguistic, and cognitive factors affecting children\'s implicature acquisition.
METHODS: The participants included 22 4-8-year-old autistic verbal children (mean age = 67.64 months) and 19 typically developing (TD) children who did not significantly differ in age, receptive vocabulary, and non-verbal IQ. Both groups completed a computer-based Truth Value Judgment task, assessing their knowledge of scalar (involving the number \'three\' and the quantifier \'some\') and ad-hoc implicatures. We also examined whether their implicature computation was linked to age, receptive vocabulary, non-verbal IQ, and Theory of Mind (ToM).
RESULTS: Compared with the TD controls, autistic children derived significantly fewer scalar and ad-hoc implicatures. Specifically, TD children successfully computed number and ad-hoc implicatures, contrasting to the bimodal distribution of their pragmatic vs. logical responses to quantifier implicatures. Though autistic children performed better with number implicatures slightly above the chance level, they had difficulties in computing quantifier and ad-hoc implicatures. Further, autistic children\'s knowledge of the number and ad-hoc implicatures was linked to their ToM skills.
CONCLUSIONS: These findings underscore the overall delayed implicature knowledge of young autistic children, and their low sensitivity to the implicatures is related to the core ToM deficits. Furthermore, our data confirm the coherent pattern of the earlier acquisition of number over quantifier implicatures and illuminate the distinct mechanisms underlying the computation of scalar vs. ad-hoc implicatures.

The tone values of a Tone 4 (T4) syllable are conventionally assumed to change from \'51\' to \'53\' when the syllable is followed by another T4 syllable in Mandarin Chinese. Literature focusing on T4 alternation is still inconclusive regarding the contexts for the alternations and whether the phenomenon should be better categorized as tone sandhi (i.e., represented as an abstract phonological rule in mental grammar) or tonal coarticulation (i.e., a natural articulation phenomenon at the phonetic level). The current study probes into these issues by focusing on disyllabic pseudowords, right-branching trisyllabic words as well as unstructured trisyllabic and quadrisyllabic digits. Productions from a total of 148 participants were collected and fundamental frequency (f0) contours, vowel lengths and f0 slopes were included in the analysis. The results from the experiments supported the tonal coarticulation view and showed that the trigger for the alternations was the high-onset tones following T4. Implications to the phonological analysis on tonal alternations in Mandarin Chinese are discussed.

BACKGROUND: Individuals with amnestic mild cognitive impairment (aMCI), especially for those with multidomain cognitive deficits, should be clinically examined for determining risk of developing Alzheimer\'s disease. English-speakers with aMCI exhibit language impairments mostly at the lexical-semantic level. Given that the language processing of Mandarin Chinese is different from that of alphabetic languages, whether previous findings for English-speakers with aMCI can be generalized to Mandarin Chinese speakers with aMCI remains unclear.
OBJECTIVE: This study examined the multifaceted language functions of Mandarin Chinese speakers with aMCI and compared them with those without cognitive impairment by using a newly developed language test battery.
METHODS: Twenty-three individuals with aMCI and 29 individuals without cognitive impairment were recruited. The new language test battery comprises five language domains (oral production, auditory and reading comprehension, reading aloud, repetition, and writing).
RESULTS: Compared with the controls, the individuals with aMCI exhibited poorer performance in the oral production and auditory and reading comprehension domains, especially on tests involving effortful lexical and semantic processing. Moreover, the aMCI group made more semantic naming errors compared with their counterparts and tended to experience difficulty in processing items belonging to the categories of living objects.
CONCLUSIONS: The pattern identified in the present study is similar to that of English-speaking individuals with aMCI across multiple language domains. Incorporating language tests involving lexical and semantic processing into clinical practice is essential and can help identify early language dysfunction in Mandarin Chinese speakers with aMCI.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is one of the debilitating complications after breast cancer treatment. Several forms of patient-reported outcome measures (PROMs) were developed to evaluate the severity of BCRL based on the patients\' perspective. LYMPH-Q Upper Extremity Module is a newly developed questionnaire for BCRL. This study aimed to demonstrate the process of translation and cultural adaption from English to Mandarin Chinese.
RESULTS: The translation process followed the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) best-practice guidelines for the translation and cultural adaption of PROM. The process included four steps: forward translation, back translation, back translation review, and patient interviews. In total, five patients with BCRL were recruited for patient interviews. The forward translation step involved two professional translators whose native language was Mandarin Chinese. A reconciled translated version was produced. In the back translation step, the reconciled translated version in Mandarin Chinese was sent to another professional translator whose native language was English. The back-translated version in English was sent back to the developer of LYMPH-Q for review. In this step, 22 items were revised. In the final step of patient interviews, 15 items were revised based on the patients\' feedback.
CONCLUSIONS: The development of Mandarin Chinese version of LYMPH-Q Upper Extremity Module and its utilization in conjunction with the existing objective measures could provide a more well-rounded picture of the status of patients with BCRL worldwide.

The current study investigates the average effect: the tendency for humans to appreciate an averaged (face, bird, wristwatch, car, and so on) over an individual instance. The effect holds across cultures, despite varying conceptualizations of attractiveness. While much research has been conducted on the average effect in visual perception, much less is known about the extent to which this effect applies to language and speech. This study investigates the attractiveness of average speech rhythms in Dutch and Mandarin Chinese, two typologically different languages. This was tested in a series of perception experiments in either language in which native listeners chose the most attractive one from a pair of acoustically manipulated rhythms. For each language, two experiments were carried out to control for the potential influence of the acoustic manipulation on the average effect. The results confirm the average effect in both languages, and they do not exclude individual variation in the listeners\' perception of attractiveness. The outcomes provide a new crosslinguistic perspective and give rise to alternative explanations to the average effect.

This article presents a comprehensive dataset containing two types of similarity measures for 23 Mandarin consonant phonemes: perceptual and featural measures. The perceptual measures are derived from confusion matrices obtained through native speakers\' identification tasks in quiet and noise-masked conditions. Specific perceptual measures, including confusion rate and perceptual distance, are calculated based on these matrices. Additionally, a phonological feature system is proposed to evaluate the featural differences between each pair of consonants, providing insights into phonological similarity. The dataset reveals a significant positive correlation between the perceptual and featural measures of similarity. Furthermore, distance matrices are generated using the perceptual distance data, and a hierarchical cluster dendrogram is plotted using the unweighted pair group method with arithmetic mean (UPGMA). The dendrogram shows five major clusters of consonants. Future studies can refer to this dataset for quantified perceptual measures of Mandarin consonant similarity. This dataset can also be valuable for future research exploring consonant similarity in perceptual and phonological domains, as well as investigating the influence of linguistic and extralinguistic factors on consonant perception.
