What the literature leaves open

  • Investigate the effects of L2 progressive aspect saliency on L1 motion event processing in other language pairs. Examine the relationship between L2 progressive aspect saliency and L1 motion event processing in different linguistic and cultural contexts. Explore the potential applications of the findings in language teaching and learning.

    The Effects of L2 Progressive Aspect Saliency on L1 Motion Event Processing: Evidence from Chinese Learners of English and German · 2026 · DOI

  • There is limited empirical evidence on L2-to-L1 effects on cognitive processing. Prior research has focused on the influence of L1 on L2, with less attention to the reverse influence.

  • Further research could investigate the effect of the speaker's intention on truth-value judgments in different contexts. Research could also explore the relationship between truth-value judgments and other cognitive processes, such as reasoning and decision-making.

    Truth-value judgments · 2026 · DOI

  • The assumption that people have a core, stable concept of truth and that it is shared across participant pools has not been thoroughly tested. The influence of truthfulness on truth-value judgments has not been fully explored.

    Truth-value judgments · 2026 · DOI

  • Although well studied, the weighing of sensory information and the extent to which this integration influences visual perceptual judgments is still poorly characterized and understood.

  • Prior studies examining AD-related HFC alterations have largely been limited to small cohorts and basic statistical comparisons, yielding inconsistent findings.

    Hierarchical reconfiguration of interhemispheric dialogue in Alzheimer’s disease: a multicenter analysis · 2026 · DOI

  • Although existing studies have discussed this through subjective questionnaires and physiological methods, the underlying neural mechanisms have not been thoroughly explored.

  • Murphy and Medin (1985) have argued that categorization models that view concepts as a collection of attributes and categorization as based solely on attribute matching are insufficient to explain conceptual coherence.

    Family resemblance, conceptual cohesiveness, and category construction · 1987 · DOI

  • (1984) required, but future research should address more global cohesion issues.

  • The study faces the challenge of operationalizing interpretive variability in a tractable form. The 'contextual mediator' (C) remains conceptually broad and aggregates multiple dimensions without fully decomposing their internal cognitive architecture. The study must balance the need for analytical consistency with the need to preserve contextual variability.

    Meaning as Distribution: A U–M–C Model of Contextual Interpretation in Bangla · 2026 · DOI

  • The dataset remains exploratory in scale and was designed primarily for theoretical operationalization rather than large-scale statistical generalization. Interpretive weighting inevitably involves annotation-based judgment. The 'contextual mediator' (C) remains conceptually broad and aggregates multiple dimensions without fully decomposing their internal cognitive architecture.

  • The mechanisms underlying the difference in emotional expression in L1 and L2 are poorly understood.

    What underlies differences in emotional expression in L1 and L2? Examining the lexical properties of narratives · 2026 · DOI

  • The lack of understanding of the [X yǔ fǒu] complex and its relation to polar questions. The need to explore the properties of the [X yǔ fǒu] complex and its contextual categorization.

    Contextually categorizing eventive polar questions · 2026 · DOI

  • To further explore the shared functions of applicatives and serial verb constructions in Central Salish languages. To examine the semantics of verbs in relation to SVCs. To investigate the areal feature of verb serialization in coastal languages.

    Making do without prepositions: Exploring serial verb and applicative shared functions in Central Salish · 2026 · DOI

  • The lack of understanding of the shared functions of applicatives and serial verb constructions in Central Salish languages. The need to explore the link between prepositions and applicatives in the broader linguistic literature.

    Making do without prepositions: Exploring serial verb and applicative shared functions in Central Salish · 2026 · DOI

  • Future studies should investigate the acquisition of English genitives by L2 learners from different linguistic backgrounds. Future studies should explore the role of other factors, such as lexical frequency and pragmatic context, in the acquisition of English genitives. Future studies should develop more effective teaching methods for English genitives.

    The Effects of Animacy and Complexity on the Morphosyntactic Acquisition of English Genitives by Jordanian Arabic Speakers · 2026 · DOI

  • There is a lack of research on the acquisition of English genitives by L2 learners. Previous studies have not considered the interaction between semantic and structural factors in the acquisition of English genitives. The study aims to fill this gap by exploring the effects of animacy and complexity on the acquisition of English genitives by Jordanian Arabic speakers.

    The Effects of Animacy and Complexity on the Morphosyntactic Acquisition of English Genitives by Jordanian Arabic Speakers · 2026 · DOI

  • The field of cognitive science has been criticized for relying too heavily on English-speaking participants. The dominance of English speakers in cognitive science has biased the field and limited generalizations about the human mind.

    LANGUAGE, COGNITION, AND IDENTITY IN MOTION: HOW LINGUISTIC EXPERIENCE SHAPES THOUGHT AND THE SELF IN MULTILINGUAL LIVES · 2026 · DOI

  • Further study of the construction's semantic preference and prosody. Analysis of the construction in different linguistic contexts. Investigation of the construction's use in language teaching and learning.

    Semantic preference and prosody of the ‘aftermath of N’ construction: A corpus-based investigation · 2026 · DOI

  • The 'aftermath of N' construction has not been thoroughly investigated. The construction's semantic preference and prosody have not been fully understood.

    Semantic preference and prosody of the ‘aftermath of N’ construction: A corpus-based investigation · 2026 · DOI

  • The study faces the challenge of analyzing complex phraseological units. The research requires a deep understanding of cognitive linguistics and phraseology. The study needs to account for cultural and linguistic differences between Czech and Polish.

    Obraz lva v češtině a polštině – komparativní studie · 2026 · DOI

  • Future research could explore the linguistic picture of other animals in Czech and Polish. The study suggests further analysis of phraseological units in other languages.

  • The complexity of language, - The difficulty of studying language in relation to cognition, - The need to integrate theoretical linguistics and psycholinguistics

    Psychological Science and Linguistic Theory · 2026 · DOI

  • Further study of the relationship between language and cognition, - Further analysis of language comprehension and production, - Examination of the implications of Artificial Intelligence for the theory of linguistic knowledge

  • Further analysis of the seven-level topological paradigm and its implications for the study of media franchises. The application of the study's findings to the analysis of other media franchises and their discourses. The development of new methods for the study of cognitive-spatial architectures in media franchises.
