Foreign language learning for active aging: Cognitive and psychosocial benefits of Chinese older adults learning English Yiran Che, Lihe Huang Educational Gerontology, 2026 Foreign language learning shows significant potential to improve older adults’ language skills, cognitive functions, and mental health, thereby promoting active aging. This quasi-experimental mixed-methods study examined the cognitive and psychosocial benefits of a 5-month community-based English learning program among 24 Chinese older adults. This research combined quantitative measures (cognitive and psychological tests) with qualitative thematic analysis on interviews concerning participants’ learning experiences and perceived outcomes. Results indicated statistically significant improvements in global cognition, delayed recall, and working memory. Thematic analysis revealed three key themes: (1) the convivial learning atmosphere, (2) the growth in self-efficacy, (3) stronger social connection. The findings indicate that foreign language learning facilitates the interconnected development of human, social, and identity capital among older adults, affirming the role of language resources as a viable pathway to active aging.
Which dependency distance measure best reflects cognitive abilities? Evidence from oral production of older adults with varying cognitive levels Tsy Yih, Dian Ding, Yiran Che, Lihe Huang Linguistics Vanguard, 2026 Dependency distance is a widely used measure of syntactic complexity, often considered to reflect cognitive abilities such as memory. However, empirical support for this claim remains limited. This study aims to examine whether dependency distance (DD) measures are associated with global cognitive function and single-domain memory performance, and identifies which variant best reflects these abilities. A sequential picture description task elicited clinical speech data from Mandarin-speaking older adults with varying cognitive levels. Multiple regression analyses are used to examine relationships between several DD variants and cognitive performance, as measured by the Montreal Cognitive Assessment–Basic (MoCA-B) and a single-domain Memory Index Score. Results show that all DD variants associated with sentence length are significantly correlated with global cognitive level, whereas removing the influence of sentence length substantially reduces their discriminative power. Among them, mean dependency distance per sentence is the best indicator of cognitive status. In contrast, no DD measure shows a significant association with the memory index. These findings suggest that DD measures can capture speakers’ global cognitive status, with sentence length playing a key role. The study deepens our understanding of the relationship between language and cognition, providing empirical evidence for the Cognitive Commitment in usage-based linguistics.
Semantic priming and ERP correlates of predictive processing in Chinese aMCI patients Jingjing Yang, Jing Wang, Lihe Huang Applied Psycholinguistics, 2025 Purpose: One of the typical symptoms of patients with aMCI is impaired semantic memory, but it remains unclear whether this impairment affects all types of semantic relationships equally. The primary goal of this study is to assess whether there are differences in the performance of aMCI patients and healthy older adults in tasks involving antonymic and categorical semantic relationships. Method: A delayed congruency judgment task involving different types of semantic relationships (antonymic and categorical) was conducted on 13 normal aging adults and 13 aMCI patients. Participants were presented with word cues for antonyms or category exemplars, followed by targets that were either congruent or incongruent with the cues. Electrophysiological data were recorded simultaneously. Results: The application of the delayed congruency judgment task across various semantic relationships led to the following main findings: 1) Different semantic relationships exhibit distinct semantic priming characteristics. Antonym relationships are highly restricted lexical-semantic relations, allowing participants to make precise predictions, while categorical relationships are less restricted, leading participants to engage in graded activation and activate related features; 2) This study suggests that aMCI patients may only be able to activate specific semantic features when processing antonym relationships and are unable to make precise predictions. In contrast, their impairment in categorical relationships primarily manifests as a narrower range of activation during graded activation.
Older adults’ resistance to engaging in reminiscence therapy: A multimodal perspective Zhongquan Ma, Lihe Huang Discourse and Communication, 2025 This study employs multimodal conversation analysis to examine the precursors of resistance displays during Reminiscence Therapy (RT) sessions, the format of the resistance exhibited by Chinese older adults with mild cognitive impairment (MCI), and the ways it was managed by caregivers. It is found that older adults with MCI display resistance through behaviors like initiating repair, denying question premises, changing topics, refusing overtly, being silent, laughing, and giving minimal responses. Non-verbal cues such as gestures, head movements, averted gaze, and facial expressions are also employed to convey their resistance. In response, caregivers employ various facilitative practices to counter this resistance. Resistance occurs when the assumptions embedded in the caregiver’s question conflict with what the older adults have access to, or the question may infringe on the older adult’s epistemic rights. Our findings also highlight the dynamic and collaborative construction of power through negotiation of resistance and facilitation from epistemic perspective. These insights offer valuable guidance for enhancing the effectiveness of RT and fostering a more collaborative relationship between participants during RT sessions.
Lexical and semantic features of Chinese-speaking older adults with mild cognitive impairment across elicitation methods Yiran Che, Lihe Huang Aphasiology, 2025 Purpose Although linguistic features in connected speech provide a valuable tool for identifying mild cognitive impairment (MCI), heterogeneous measures and tasks in MCI discourse studies have yielded widely varying outcomes, and the diversity of languages studied is highly limited. This study aims to identify effective measures and tasks to differentiate Chinese-speaking older adults with and without MCI, and to explore task-related differences in connected speech.Method Speech samples from 30 Chinese-speaking older adults with MCI and 30 healthy controls (HCs) were collected using the single picture, picture sequence, and story retelling tasks. Lexical and semantic measures, including parts of speech, lexical diversity, informativeness, conciseness, and efficiency, were analyzed using univariate 2 × 3 mixed ANOVAs with Bonferroni corrections.Results MCI participants produced significantly fewer information units and had lower success rates in generating information units across all three tasks than HCs. There were no significant differences in lexical measures between the MCI and HC groups in the picture sequence task. In the story retelling task, MCI participants showed significantly lower lexical efficiency than HCs. When comparing tasks, the story retelling task was associated with the lowest lexical diversity, information efficiency and density, and success rate of information unit produced. Speech samples elicited by the picture sequence task showed higher lexical efficiency but lower semantic richness than the single picture task, with no significant differences in the success rate of information units produced.Conclusions Cognitive ability and task type both influence discourse performance. Regarding effective measures and tasks, fewer information units and a lower success rate of information units produced are reliable MCI indicators in each task, while lexical measures are less sensitive than semantic measures. The single picture task shows strong validity in identifying MCI, regardless of lexical or semantic measures employed. Regarding differences among tasks, the results suggest that the story retelling task is more demanding, and single picture and picture sequence tasks are better suited for analyzing lexical richness and semantic deficits of MCI patients. This study enhances the understanding of MCI in Chinese-speaking individuals and highlights the task-related differences in connected speech.
Word-Frequency Distributions in Chinese- and English- Speaking Older Adults: An Analysis across Languages and Cognitive Statuses Tongfu Yang, Lihe Huang, Tsy Yih Glottometrics, 2025 This study investigates how the word-frequency distributions in spoken language reflect cross-linguistic and cognitive differences in older adults. We analyzed Cookie Theft picture descriptions from 96 older adults: 48 Mandarin speakers (24 cognitively impaired and 24 cognitively normal) and 48 English speakers (24 cognitively impaired and 24 cognitively normal) and modeled their word frequency distributions using three functions: Zipf, Zipf-Mandelbrot, and Exponential model. All three models showed excellent goodness of fit at both group and individual levels, indicating that the basic Zipfian structure of lexical distributions is preserved in late life and is not disrupted by mild cognitive impairment. As for the fitting parameters, however, the decay parameter a in the Exponential and Zipf models consistently distinguished Mandarin from English, suggesting that language-specific lexical patterns are robustly encoded in the slope of the distribution but that adding a shift parameter can dampen how clearly a reflects them. By contrast, differences between cognitive groups were weak and inconsistent, implying that parameter a provides only a coarse and context-dependent reflection of cognitive status in short, constrained picture-description tasks.
Identifying novel linguistic biomarkers of mild cognitive impairment in Mandarin-speaking older adults: A quantitative syntactic approach Tsy Yih, Yiran Yang, Mu Yang, Haitao Liu, Lihe Huang Clinical Linguistics and Phonetics, 2025 Mild Cognitive Impairment (MCI) is an early symptom of Alzheimer's disease, commonly observed in older adults. The use of low-cost language biomarkers is becoming an emerging trend. This study aims to investigate whether recently proposed measures in the field of Quantitative Syntax and their combinations have the potential to serve as biomarkers for distinguishing between the MCI and cognitively normal (CN) groups. A portion of the Chinese corpus MCGD (CN = 25, MCI = 16) was used. The elderly participants performed a sequential picture description task to produce connected speech. The transcription and annotation were semi-automatically conducted and manually checked. Eleven dependency-based syntactic features were calculated. We assessed the discriminability of both univariate features and multivariate feature combinations using support vector machine. Results show that all features can be grouped into four clusters. Most measures within the largest cluster demonstrate high intercorrelations and are statistically significant in distinguishing between the MCI and CN groups. Among these, mean dependency distance (MDD) exhibits the strongest discriminative ability (AUC = 0.791 [0.610, 0.944]). Two hierarchical features have relatively weaker performance, while dependency direction indicators show almost no group differentiability. Several feature combinations identified slightly improved performance, but the difference was not statistically significant. Our findings suggest that the classic syntactic biomarker MDD remains the best-performing measure for distinguishing between MCI and CN for Mandarin-speaking older adults, while most dependency-based syntactic measures can serve as alternative markers. In the future, combining MDD with features in other domains holds promising potential for early diagnosis.
Power Relations in Older Adults' Cognitive Interaction in Clinical Setting: A Multimodal Pragmatic Perspective Zhongquan Ma, Lihe Huang Chinese Journal of Applied Linguistics, 2024 This study explored the construction of power relations in the cognitive assessment of older adults within the Chinese clinical context. Data is derived from audio and video recordings that nine older adults produced in the cognitive assessment of the Chinese version of the Montreal Cognitive Assessment-Basic (MoCA-B), which were then annotated and analyzed from a multimodal pragmatic perspective. The study reveals that examiners and older adults employed various speech acts to achieve distinct communicative goals, with power relations between them being reflected through these speech acts. Examiners tend to claim high power, utilizing discourse strategies such as request, interruption, evaluation, rhetorical questions, and directive speech acts. In contrast, older adults assert high power through directive speech acts, rhetorical questions, and interruptions. Both parties also exhibit low power by using confirming questions and explanations. Additionally, gestures, smiles, prosody features, and other non-verbal communicative resources are synergistically employed to exercise power. The interactive mechanism of constructing power relations reveals that age affects older adults’ power relations construction even in a professional setting of the Chinese context. The negotiation between the advanced age of older adults and the expertise of examiners jointly shapes power relations in their interactions.
