Developmental Language Disorder (DLD) is a common neurodevelopmental condition that affects language acquisition in children. However, standardized diagnostic tools for Tunisian Arabic, a widely spoken yet underrepresented dialect, is still lacking. This study presents a multimodal biomedical informatics framework that integrates clinical assessments, speech recordings, and artificial intelligence (AI) for early DLD detection. Three linguistic tasks (the CLT Task, the Arabic Verb Evaluation Task, and the Nonword Repetition Task) were adapted for Tunisian Arabic, and spontaneous speech samples were collected from children with typical development and those with DLD. Statistical analyses revealed significant deficits in verb production, past-tense morphology, and phonological memory in the DLD group. For automated screening, we developed two systems: a Random Forest classifier based on structured clinical and linguistic features and a multimodal deep learning model using Wav2Vec2 acoustic embeddings. The best model achieved an F1 score of 0.85, demonstrating the feasibility of AI-assisted DLD screening. This work introduces the first standardized dataset and computational baseline for DLD in Tunisian Arabic, providing clinically relevant tools for early identification and supporting research on underrepresented Arabic dialects. This work also highlights future implications, including potential applications in early screening, the integration of acoustic markers, and the development of culturally adapted assessment tools for underrepresented languages.

Interpreting event completion is a core difficulty in second language acquisition, as it underpins temporal reference and communication. This study investigates how L1 Urdu Pakistani learners of English acquire telicity, a semantic property that distinguishes completed and ongoing events. The analysis centers on bounded and unbounded object noun phrases (NPs) in marking telic/atelic events within accomplishment predicates. In English, telicity is compositionally encoded through verb types, object NPs, and temporal adverbials, whereas Urdu relies on aspectual morphology, creating challenges for learners in mapping event completion. The study is framed within the Full Transfer Full Access (FTFA) model and the Interpretability Hypothesis (IH). Data were collected through an Acceptability Judgment Task (AJT) administered to Pakistani ESL learners at elementary, intermediate, and advanced levels, alongside a native English control group. Results support the FTFA model, revealing a significant developmental trajectory where accuracy in distinguishing telic/atelic contrasts increases with proficiency. At the elementary level, an L1-based accuracy gradient emerged across NP types, reflecting the transfer of Urdu nominal underspecification. While advanced learners demonstrated successful restructuring in bounded contexts, partial support for the IH was found in atelic contexts. Continued divergence from native judgements in unbounded NP conditions highlights a persistent mapping deficit at the syntax–semantics interface. The study advances second language event semantics, emphasizing the role of object structure and cross-linguistic influence in the acquisition of L2 event boundaries. Full article

The present study investigates Japanese-speaking children’s interpretation of verb-echo answers (VEAs) to yes/no questions. Previous syntactic research suggests that VEAs are derived via ellipsis, with Japanese VEAs specifically analyzed as being derived by TP ellipsis involving verb movement. This study assumes that parameter settings for pro-drop and verb movement are prerequisites, and that the knowledge of both the possibility of VEAs being answers to questions with existential indefinite subjects and the possibility of the adverb-inclusive interpretation are required for acquiring Japanese VEAs. We conducted a series of three experiments with 4- to 6-year-olds acquiring Japanese to test whether they have knowledge of these factors relevant to Japanese VEAs. The results of the experiments indicate that most children correctly assigned adult-like interpretations to VEAs for questions involving existential indefinite subjects and adverbs. These findings support the hypothesis that children’s VEAs in Japanese are derived through verb movement and TP ellipsis, and suggest that parameters for pro-drop and verb movement, together with evidence regarding the possibility of VEAs to questions with existential indefinite subjects and the possibility of the adverb-inclusive reading, may determine the adult-like interpretation of Japanese VEAs.

Early word learning is a critical milestone for children, yet autistic children often experience delays in language development. Social communication differences are a core feature of autism and may contribute to variability in learning experiences. Prior research has shown that word-level features such as iconicity, concreteness, and input frequency shape the timing of word learning, but less is known about the role of social word features. This study examined whether social word ratings predict when words tend to be acquired by autistic and non-autistic children. Social word ratings were examined as a predictor of word-level autistic and non-autistic acquisition normative data, while accounting for word input frequency. Regression analyses demonstrated that social ratings significantly predicted vocabulary acquisition, even after controlling for word frequency. Additional analyses demonstrated that socialness ratings continued to be a unique predictor of word acquisition when other affective features of words were included in the model (i.e., arousal and valence); this was also the case when iconicity and concreteness were included. Importantly, differences in group and interactions with social ratings and group were not statistically significant in any of the models. Lastly, the pattern of highly social words being acquired later in vocabulary development was strongest for nouns; the association was non-significant when examining verbs separately. Thus, in addition to previously studied word features like concreteness, imageability, and iconicity, social word features are predictive of vocabulary acquisition. These findings highlight an overlap in word features that influence learning in autistic and non-autistic children. Full article

Some generative linguists report that in formal settings, learners of English as a foreign language often strive to acquire morphemes such as the third-person singular –s and produce utterances such as *he play. This study reviews generative linguistics, psychology, neuroscience, and biolinguistics, examining how speech and other forms of action involve hierarchically organised groups (chunks) of words or acts that are invariably produced in linear order. Chunks contribute to brain efficiency, facilitating acquisition and enabling brain automaticity. A study was conducted to improve the accuracy rates of sentence segments featuring the third-person singular –s (e.g., “he VERB+s”) by orally rehearsing chunk-based sentences (e.g., [He plays] [a lot]). Sixty-four children from three Spanish schools, learning English as a foreign language and aged 8–11, participated in this study. The participants, divided into a control group and two experimental groups, completed an oral sentence transformation task following a pre-test–post-test design. The Wilcoxon test showed statistically significant results for the experimental groups after the administration of oral chunk-based training. Quartiles and deciles demonstrated improvement in these groups. The findings suggest that oral chunk-based training could foster chunk and morpheme acquisition. This pedagogy might enhance brain efficiency in learning and promote automatic speech. Full article

The rise of English-medium instruction (EMI) in higher education presents challenges for supporting language development alongside disciplinary learning, as it is typically delivered by content specialists with limited time and little or no background in language pedagogy. Against this backdrop, this study examines the effectiveness of computer-assisted content-based structured input (CBSI), compared to input flood (IF) and unmodified disciplinary input (Control), in enhancing students’ acquisition of English verb patterns in an EMI university course in Poland. All participants received the same asynchronous, computer-assisted disciplinary instruction, aligned with the course syllabus. The groups differed only in the type of input enhancement, which was developed by a language specialist in coordination with the course instructor. A split-block design was used to measure learning gains through a pre-test, post-test, and delayed post-test. Students in the CBSI group showed significantly greater and more sustained improvement than those in the IF and Control groups. These findings support CBSI as an effective and pedagogically feasible way to promote language development in EMI, integrating linguistic and disciplinary concerns while respecting the roles and integrity of both domains.

English phrasal verbs are ubiquitous and challenging for second language (L2) learners, particularly for those whose first language does not have an equivalent structure. This study investigates the facilitative role of three distinct L2 practice types in promoting English phrasal verb acquisition. Eighty first-year college students from China were randomly assigned to three groups: the continuation group, which was first presented with an input text and then required to complete it; the retrieval group, which was first presented with the input text and then required to engage in retrieval practice; and the trial-and-error group, which was first required to engage in trial-and-error practice before reading the input text. The effectiveness of these practice types was compared via both an immediate post-test and a 1-week-delayed post-test. The results showed that in the immediate post-test, the continuation group performed comparably with the retrieval group but outperformed the trial-and-error group. However, in the 1-week-delayed post-test, the continuation group significantly outperformed the other two groups. The findings revealed that the continuation writing task not only initially equips learners with declarative knowledge and subsequently closely integrates static L2 learning with dynamic idea expression but also enhances learners’ task self-efficacy, thereby optimally promoting phrasal verb learning and retention.

Languages vary in their availability of productive endocentric bare-stem compounds (e.g., flower hat) and a range of complex predicates (separable verb-particles, double object datives, adjectival resultatives, put-locatives, make-causatives, and perceptual reports). To account for these cross-linguistic variations, two parameters have been proposed: the Compounding Parameter (TCP), which governs the formation of bare-stem compounds, separable verb-particles, and adjectival resultatives, and the Small Clause Parameter (SCP), which determines whether a verb can take a small clause complement. These parameters make testable predictions about children’s acquisition. If TCP and SCP are on the right track, we would expect correlations in the acquisition of structures governed by each parameter. This study examines these predictions by analyzing longitudinal corpora from 23 English-speaking children, assessing both the correlation between the acquisition of different structures and their acquisitional ordering. Our findings support both TCP and SCP, confirming that the acquisition of bare-stem compounds is closely associated with that of separable verb-particles, while the acquisition of (some) complex predicates is related. In addition, our results offer new insights into the potential triggers that children use to set each parameter. These findings contribute to our understanding of language variation and the role of parameter setting in first language acquisition. Full article

Effective language processing relies on pattern detection. Spanish monolinguals predict verb tense through stress–suffix associations: a stressed first syllable signals present tense, while an unstressed first syllable signals past tense. Low-proficiency second language (L2) Spanish learners struggle to detect these associations, and we investigated whether they benefit from game-based training. We examined the effects of four variables on their ability to detect stress–suffix associations: three linguistic variables—verbs’ lexical stress (oxytones/paroxytones), first-syllable structure (consonant–vowel, CV/consonant–vowel–consonant, CVC), and phonotactic probability—and one learner variable—working memory (WM) span. Beginner English learners of Spanish played a digital game focused on stress–suffix associations for 10 days and completed a Spanish proficiency test (Lextale-Esp), a Spanish background and use questionnaire, and a Corsi WM task. The results revealed moderate gains in the acquisition of stress–suffix associations. Accuracy gains were observed for CV verbs and oxytones, and overall reaction times (RTs) decreased with gameplay. Higher-WM learners were more accurate and slower than lower-WM learners in all verb-type conditions. Our findings suggest that prosody influences word activation and that digital gaming can help learners attend to L2 inflectional morphology. Full article

Acquiring prosodic focus marking in a second language (L2) is difficult for learners whose native language utilizes strategies that differ from those of the target language. German typically uses pitch accents (L+H*/H*) to mark focus, while (Modern Standard) Arabic preferably employs a syntactic strategy (word order) or lexical means. In Syrian Arabic, a variety which is predominantly oral, pitch accents are used to mark focus, but the distribution and types are different from German. The present study investigates how Syrian Arabic learners of German prosodically mark focus in L2 German. A question–answer paradigm was used to elicit German subject-verb-object (SVO)-sentences with broad, narrow, or contrastive focus. Productions of advanced (C1, N = 17) and intermediate (B1/B2, N = 8) Syrian Arabic learners were compared to those of German controls (N = 12). Like the controls, both learner groups successfully placed pitch accents on focused constituents. However, learners, especially those with lower proficiency, used more pitch accents in non-focal regions than the controls, revealing challenges in de-accentuation. These may result from the larger number of phrase boundaries in learners’ productions, which in turn might be explained by transfer from the L1 or aspects of general fluency. Learners also differed from the controls with respect to accent type. They predominantly used H* for narrow or contrastive focus (instead of L+H*); proficiency effects played only a minor role here. Our study hence reveals an intricate interplay between cross-linguistic influence and proficiency in the L2 acquisition of prosodic focus marking, targeting a language pair so far underrepresented in the literature (German vs. Syrian Arabic).

Background/Objectives: Verbs are considered to be more abstract than nouns, as they represent actions, states, and events, which are less tangible, more flexible in their meaning and thus less univocally specified. It has been suggested that children acquire abstract concepts based on their linguistic contexts of use, making use of semantic and syntactic cues. By contrast, according to theories of embodied cognition, conceptual knowledge is based on physical and perceptual interaction with the world. The present study investigates whether the verbal and the visual modality produce similar or different results in the processes of construction and reactivation of novel verbs, corresponding to new compositional abstract concepts, in children of different ages. In Experiment 1, the acquisition of the concept was determined based on the quality of verbal explanation; in Experiment 2, participants were asked to decide whether a visual representation fitted the concept or not. Thus, response modality could be either explicit or implicit, and either congruent or incongruent with respect to learning modality. Methods: In Experiment 1, 100 children from grade 1 to 5 were asked to explain the meaning of verbs introduced via verbal or visual instances. In Experiment 2, 15 children aged 8 to 10 had to judge pictures as (not) being examples of previously verbally or visually presented novel verbs. Results: The results of Experiment 1 show more accurate explanations after verbal presentation across all grades. In Experiment 2, verbal presentation was no longer associated with more accurate matching responses, but rather with slower decision times. Conclusions: Modality congruence, explicitness and linguistic (semantic and syntactic) factors were all shown to play a role, which is discussed in a developmental perspective. Full article

Background/Objectives: Although the embodiment of action-related language is well-established in the mother tongue (L1), less is known about the embodiment of a second language (L2) acquired later in life through formal instruction. We used the high temporal resolution of ERPs and topographic ERP analyses to compare embodiment in L1 and L2 and to investigate whether L1 and L2 are embodied with different strengths at different stages of linguistic processing. Methods: Subjects were presented with action-related and non-action-related verbs in a silent reading task. Subjects were late French–German and German–French bilinguals, respectively, and we could therefore collapse across languages to avoid common confounding between language (French and German) and order of acquisition (L1, L2). Results: We could show distinct effects of embodiment and language. Embodiment affected only the sensory and lexical stages of processing with increased strength and power of the N1 component for motor vs. non-motor verbs, and language affected the lexical and semantic stages of processing with stronger P2/N400 components for L2 than for L1. Non-motor verbs elicited a stronger P1 component in L2. Conclusions: Our results suggest that processing words in L2 requires more effortful processing. Importantly, L1 and L2 are not embodied differently, and embodiment affects early and similar stages of processing in L1 and L2, possibly integrating other process of action–language interaction Full article

It is widely accepted that languages organize speech material into prosodic domains, which are hierarchically arranged. However, it is still a matter of debate whether this prosodic hierarchy is composed of a small number of universal categories, or whether these prosodic categories are language-particular and emergent. In this article, we concentrate on one of these categories, the foot, and we investigate its role in European Portuguese (EP). Whereas research on EP has shown that other prosodic domains commonly found crosslinguistically are active in the language, it seems that EP may lack this prosodic constituent. Therefore, the goal of this article is to systematically investigate the role of the foot in a number of areas within EP grammar. In our study, we defend some new approaches to several long-standing issues in EP phonology and we conclude that many facts of the language can be, in fact, better understood resorting to the foot domain. Namely, the distribution of stress in the most frequent morphological classes (thematic non-verbs and present tense verbs), -inh-/-zinh- diminutive formation, the domain for regular vowel reduction, obligatory glide formation, the stress window, and poetic rhyme seem to benefit from a metrically-governed account. By contrast, other facts, such as vowel lowering, word clipping, minimal words, secondary stress, and schwa deletion are shown not to be conditioned by the foot in EP. Importantly, the evidence we found for metrical structure only cues the prominent foot of the word, suggesting that pretonic material may not be footed. All in all, in addition to shedding light on facts previously poorly understood, and exposing some noteworthy specificities of EP in the realm of Romance languages and other varieties of Portuguese, we draw implications for the universal characterization of the prosodic hierarchy and its acquisition.

The acquisition of deictic verbs is a significant milestone in language development. This complex process requires an understanding of the interplay between the personal pronouns “I/you” and deictic verbs. Although demonstrating the cognitive processes associated with deictic shifting through data is valuable, research issues regarding data accuracy and the spatial arrangement of the self and other remain unresolved. This pilot study aimed to quantitatively measure the body movements of Japanese-speaking children during their utterances of “come/go”. Twelve typically developing children aged 6–7 participated in this study. Multiple scenarios were set up where the researcher presented phrases using “come/go” with deictic gestures, such as moving one’s upper body forward or backward, and the participant replied with “come/go”. When performing a role, the researcher sat face-to-face or side-by-side with the participant, depending on the type of question–response. It is possible that there is a learning process whereby verbal responses using “come/go” align with corresponding body movements in the specific question type. This process is deeply involved in the development of perspective-taking abilities. Future research with relatively large samples and cross-cultural comparisons is warranted to deepen the understanding of this linguistic acquisition process and its implications. Full article

This study shows two parallelisms between (i) the acquisition process of English verb–particle constructions (VPCs) by children in the process of acquiring English as a native language (henceforth ENL children) and (ii) that of Japanese verb–verb compounds (VVCs) by children in the process of acquiring Japanese as a native language (henceforth JNL children) using the CHILDES database. First, both JNL and ENL children produce creative N–N compounds and complex predicates during the same period, in line with the proposal by Snyder that the Compounding Parameter (TCP) is set to positive for both Japanese and English languages. Second, particles or verbs which are used to represent the path of motion in English VPCs and Japanese VVCs are produced before the VPCs and VVCs they are used in because complex predicates are created by the combination of two or more constituents, such as verbs and particles. Thus, our findings corroborate the proposal that Japanese is a [+TCP] language and suggest that Japanese makes use of VVCs instead of VPCs. Furthermore, this parallelism observed among ENL and JNL children in the acquisition process of creative N–N compounds and VPCs/VVCs, respectively, suggests that English VPCs and Japanese VVCs are related expressions in a grammatical sense. This in turn implies that VPCs and VVCs are connected by more than their semantics; indeed, it implies that they are realizational variations of the same abstract linguistic structure. Full article
