What the literature leaves open

  • In particular, all the verbs used in the experimental study were verb compounds, and thus it remains to be explored whether the findings can be generalized to NV constructions containing simplex verbs. In order to better understand how the agent-first bias develops in Mandarin-speaking children, future research is needed to directly manipulate these cues.

    Agent-First Bias in Children’s Sentence Comprehension: Evidence from Mandarin · 2026 · DOI

  • Specifically, future research might explore whether and how L2 learners adapt their L1 processing biases—such as transitioning from a late‑verb integration strat‑ egy to an early‑verb predictive strategy—when acquiring an isolating, role‑based language like Chinese.

    The Primacy of Roles over Syntactic Structures: Mental Representation of Chinese Verbs in Argument Realization · 2026 · DOI

  • In contrast to the majority of studies on L3 processing of (morpho)syntax, which have focused on cross-linguistic influence (CLI), this factor has not been directly investigated in the present study, thus making considerations regarding its role tentative.

    Structure-dependent sensitivity to morphosyntactic violations in L3 Norwegian: A self-paced reading investigation · 2026 · DOI

  • Studies like this one are limited by the fact that LLMs are prompt-responsive, probabilistic systems. However, in domains where symbolic and linguistic resources are insufficient, such as visual–spatial reasoning, LLMs fall short of humans. Thus, psychometric models of intelligence alone are insufficient as guides for AGI development.

    Profiles of Mind: How LLMs Perform on Assessments of Cognitive Development · 2026 · DOI

  • Apraxia of speech is a motor speech disorder frequently associated with acute neurological pathologies but remains relatively under-investigated. Consequently, the present study could provide only limited evidence regarding construct validity, while focusing on other key psychometric properties, including content validity, criterion-related validity, reliability, and responsiveness.

    The Italian version of ABA2: a new test for the assessment of apraxia of speech · 2026 · DOI

  • As such, it remains unclear whether the RTPJ activation arises from processing emotive language itself or that of emotion conveyed by the sentence. Further research is required to clarify this distinction using other emotive meanings such as ‘good’ or ‘beautiful’ and uncover the precise mechanisms of the RTPJ in the processing of emotive and emotional languages.

    Emotive language activates right temporoparietal junction, while referential language activates the left hemispheric network · 2026 · DOI

  • Whether the parameter profiles observed here generalize to other control components and to stimulus–response conflict is an open question that applying the same DDM decomposition across a battery of tasks within a single sample would resolve.

    Domain-dependent mechanisms of L2 proficiency in interference suppression: A drift-diffusion analysis of verbal and spatial Stroop in Chinese–English bilinguals · 2026 · DOI

  • This conditional pattern reconciles previously conflicting findings by showing that population characteristics, not methodological noise, drive the variability that has long characterized this literature. Moving forward, the field requires primary studies that span understudied language pairs, employ standardised proficiency measures, and report complete valence-specific data.

    A meta-analysis of Stroop task studies on bilinguals’ emotional word processing · 2026 · DOI

  • Although alterations in brain structure and function have been implicated in both post-stroke aphasia (PSA) and motor deficits, how structural-functional coupling (SFC) is affected in stroke patients with and without aphasia (nonPSA) remains unclear.

    Neurotransmitter systems underlie structure-function decoupling and recovery in post-stroke aphasia · 2026 · DOI

  • The current understanding of putative compensatory network-level mechanisms supporting lexico-semantic cognition is limited. There is a need to investigate acute network adaptation when the left posterior middle temporal gyrus is perturbed during lexico-semantic decisions. The brain's capacity to dynamically adapt to interference is not fully understood.

    Disrupting the semantic network shifts activity to domain-general brain regions · 2026 · DOI

  • Future work may investigate whether structurally driven predictive strategies extend to sentence types beyond filler–gap dependencies in Japanese, and how structurally based predictive biases develop over time, potentially shifting from linear gap-filling in early stages to structurally guided interpretation as language processing mechanisms develop.

    Proximity Loses: Real-Time Resolution of Ambiguous Wh-Questions in Japanese · 2025 · DOI

  • Future research should explore how to optimize CT instruction for learners across the InSp continuum. As discussed throughout, this proposed model should be empirically examined, and the limits and variability of its underlying mechanisms warrant further exploration.

    Ctrl + Alt + Inner Speech: A Verbal–Cognitive Scaffold (VCS) Model of Pathways to Computational Thinking · 2025 · DOI

  • Further exploration is necessary to fully understand the observed null effects. Moving forward, it will be important to determine why the modulation of cognitive control by Stroop does not affect sentence processing difficulty as measured by Kuz et al. (2024).

    The Role of Cognitive Control in Language Comprehension: Commentary on Kuz et al. (2024) · 2025 · DOI

  • Further studies on different prosodic phe‑ nomena with similar and different L1‑L2 mapping in various source and target languages, as well as more neurocognitive studies on the L2 processing of prosodic cues, would fur‑ ther strengthen the conclusions of the present paper.

    That Came as No Surprise! The Processing of Prosody–Grammar Associations in Danish First and Second Language Users · 2025 · DOI

  • Although a third of stroke survivors experience aphasia, high quality trial data on the impact of SLT and brain stimulation on important aphasia outcomes is limited to a relatively small number of trials.

    European Stroke Organisation (ESO) guideline on aphasia rehabilitation · 2025 · DOI

  • Further work is needed to understand exactly what is required for adaptation to occur and whether or when it can transfer to the wild.

    Trial-Level and Contiguous Syntactic Adaptation: A Common Domain-General Mechanism at Play? · 2024 · DOI

  • Individual differences in reading speed should be examined as a covariate for late processing measures. One limitation is that the role of emotional valence was not considered in the present study.

    Context and working memory capacity affect the processing of written irony in chinese: an eye-tracking study · 2026 · DOI

  • The of contextual priming on subsequent these facilitatory effects remains unknown, and duration of whether such transient modulation can accumulate into longer-term cognitive advantages through repeated exposure requires investigation through delayed post-tests or longitudinal designs.

    Dynamic adaptation of attentional control across bilingual interactional contexts · 2026 · DOI

  • In this case, using the lack of evidence to conclude that cognitive IDs do not play a role in language acquisition would be falling into the absence of evidence fallacy.

    Predictions of Cognitive Individual Differences in Language Acquisition: Commentary on Hulstijn (2024) · 2025 · DOI

  • One limitation of the present study is that two SNR settings were operated between two groups of participants.

    Linking Context to Language Switching: Effects of Background Noise on Bilingual Language Comprehension · 2025 · DOI

  • Future investigations could explore additional features for sample analysis and alternative strategies for sample selection and classification. A limitation of this study is its narrow scope, as only four characteristics associated with cognitive impairment were considered.

    A Novel Methodology for Data Augmentation in Cognitive Impairment Subjects Using Semantic and Pragmatic Features Through Large Language Models · 2025 · DOI

  • While these explanations should be examined further, it may be that there is not a detectable inhibition behavioral difference between monolingual and bilingual preschoolers.

    Examining the role of early bilingualism on interference suppression and prefrontal connectivity · 2025 · DOI

  • There is limited research on the Minimal Important Change (MIC) of the Chinese Western Aphasia Battery (WAB).

    Minimal important change for the aphasia quotient of the Chinese Western Aphasia Battery · 2025 · DOI

  • The between-study comparison of valence eligibility – contrasting effect sizes that included positive, negative, and neutral words against those presenting only negative and neutral words – did not account for heterogeneity and did not reach significance.

    A meta-analysis of Stroop task studies on bilinguals’ emotional word processing · 2026 · DOI

  • Fast errors (fastest bin) are commonly interpreted as reflecting impulsive responding or insufficient evidence accumulation, whereas slow errors (slowest bin) are often attributed to attentional lapses or temporary disengagement from the task…
