Language comprehension involves dynamically integrating linguistic input into coherent event representations. A common approach to investigating this process has been to examine behavioural congruency effects between linguistic and visual information. However, it remains unclear under what conditions these effects emerge and whether they reflect embodied processing or alternative cognitive mechanisms. The present study examined semantic-visual alignment of motion schema during incremental processing of Mandarin motion sentences, focusing on whether congruency effects are modulated by task demands and visual probe regions. 149 native Mandarin speakers completed either a self-paced sentence-diagram verification task or a self-paced sentence-diagram viewing task. In both tasks, participants processed segmented Chinese motion sentences, while schematic diagrams were presented either after the directional verb (e.g., jìn , ‘into’) or the landmark (e.g., bàn-gōng-shì , ‘office’). Results revealed overall congruency effects across tasks and diagram regions. Crucially, effects were stronger in the verification task than in the viewing task but remained stable across diagram regions. These findings suggest that semantic-visual alignment is sensitive to task demands but does not necessarily become stronger as the sentence unfolds. These congruency effects are open to both embodied and amodal semantic interpretations and are therefore not uniquely diagnostic of embodied processing.

This study investigates how second language (L2) learners acquire morphologically complex English words, focusing on affixal neutrality—whether suffixes preserve the phonological form and semantic transparency of the base (e.g., -ness in happiness) or trigger phonological/orthographic changes (e.g., -ity in activity). Drawing on linguistic theories of morphological decomposition and lexical representation, we examine how this property influences different dimensions of derivational knowledge. Fifty-four Mandarin-speaking secondary school EFL learners completed three receptive tasks targeting relational knowledge (morphological relatedness), syntactic knowledge (category awareness), and distributional knowledge (contextual appropriateness). Lexical items varied in affixal neutrality, and participants’ accuracy and response times were analysed across three L2 proficiency levels. Affixal neutrality significantly affected performance in the relational knowledge task, with neutral suffixes facilitating accuracy and faster responses. Effects were attenuated in syntactic and distributional tasks, suggesting domain-specific sensitivity to neutrality. L2 Proficiency was associated with higher accuracy across all three domains but did not substantially affect processing speed. These findings highlight the selective role of a theoretically motivated morphological property in L2 lexical acquisition and show how linguistic concepts such as affixal neutrality can form the basis of targeted hypotheses, bridging theoretical linguistics and empirical research in second language learning.

This study investigated how mental imagery is engaged during first language (L1) and second language (L2) speakers’ incremental sentence processing of English phrasal verbs, using a self-paced sensibility judgment task interleaved with schematic diagrams. L1 speakers showed selective compatibility effects modulated by abstractness, semantic transparency of phrasal verbs, event plausibility and the timing of visual input. In contrast, L2 learners relied more generally on visual support, reflecting weaker integration of semantic and perceptual cues. Learner-internal factors such as L2 proficiency and language dominance modulated learners’ sensitivity to integrate and resolve competing cues between semantic coherence and perceptual input. These findings support a simulation-based model of L2 comprehension, highlighting the developmental nature of sensorimotor activation in bilingual processing.

Despite abundant studies on motion events and mental simulation in first languages (L1s), research on how cross-linguistic dis/similarity – whether an L1 shares constructions with a second language (L2) – affects mental simulation during incremental L2 processing remains limited. This study used a novel self-paced reading task with video verification to investigate L1 influence on mental imagery of the dual (directional/locational) interpretation of locative prepositions. Participants included native English speakers and advanced L2 English learners whose L1s were either similar (Dutch) or dissimilar (Japanese) to English. Results revealed an L1 dis/similarity effect on the reaction times for the directional interpretation, but not for the locational interpretation, which was readily accessible across all L1 groups. Factors such as L2 proficiency and onset age of L2 acquisition were found to be constrained by L1, suggesting that L1–L2 constructional correspondence limits the influence of learner factors. These findings support the simulation-based model of L2 sentence processing.

The current study investigated from a usage‐based perspective how phrasal frequency and collocational strength of verb–preposition collocations influence preposition placement in wh ‐relative clauses. Native English speakers and Chinese learners of English as a second language of the intermediate and advanced English proficiencies completed a sentence completion task and an acceptability judgment task. The results showed that native and nonnative speakers had an overall preference for preposition stranding. Native speakers had a stronger acceptance of preposition pied‐piping than nonnative speakers; advanced learners had a stronger acceptance of pied‐piping than intermediate learners. The collocational strengths of verb–preposition combinations had a significant effect on the productive use and acceptability of preposition placement for both native speakers and advanced learners. Intermediate learners’ preposition placement was more affected by phrasal frequency. Overall, the findings confirm that the distributional properties of verb–preposition collocations influence speakers’ preference for the type of wh ‐clause structure, which provides strong support to the usage‐based account of grammar analysis and grammar acquisition.

Embodied imagery hypothesis proposes the activation of perceptual-motor systems during language processing. Previous studies primarily used concrete visual stimuli to investigate mental imagery in language processing by native speakers (NSs) and second language (L2) learners, but few studies employed schematic diagrams. The study aims to investigate mental imagery in processing prepositional phrases by English NSs and L2 learners. Using image-schematic diagrams as primes, we examine whether any mental imagery effect is modulated by target preposition (over, in), the abstractness of meaning (spatial, extended), and stimulus onset asynchrony (SOA; 1,040 ms, 2,040 ms). A total of 79 adult L2 learners and 100 NSs of English completed diagram–picture matching and semantic priming phrasal decision tasks. Results revealed interference effects on L2 processing of over phrases and under 2,040 ms SOA, but no such effects were observed in the NS group. The selective interference effects in L2 suggest different mental imagery patterns between L1 and L2 processing, and processing schematic diagram primes requires high cognitive demands, potentially leading to difficulties in integrating visual and linguistic information and making grammaticality judgments. The findings partially validate schematic diagrams as visual representations of concepts and suggest the need for further examination of schematic diagrams with varying degrees of complexity.

This study adopts the Speech Learning Model to investigate the first language (L1) influence as well as the effects of the length of residence and second language (L2) exposure on American English-speaking learners of Turkish in their productions of Turkish unrounded–rounded vowel pairs, with a particular focus on the vowel categories “new” to American English speakers (/y/, /œ/, and /ɯ/). L1 (English) and L2 (Turkish) speech samples were collected from 18 non-governmental organisation (NGO) workers. L2 experience was defined by whether the worker lived in an urban or regional environment in Turkey. Participants’ audio productions of the word list in L1 and L2 were segmented and annotated for succeeding acoustic analyses. The results show an interesting front–back variability in the realisations of the three vowels, including further back variants of the front vowels (/y/, /œ/) and more forward variants of the /ɯ/ vowel, with a substantial degree of interspeaker variability. While the analysis revealed no significant results for the length of residence, language experience was found to have a significant effect on the production of /y/ (F2) and /ɯ/ (F1/F2). This study forms a first step into the research of adult L2 acquisition in Turkish with a focus on L2 in the naturalistic workplace environment, rather than instructed settings. The findings of this study will contribute to the development of teaching materials for NGO workers learning Turkish as their L2.
