To this end, a simulation modeling was run on CEFR speaking proficiency assessment using MATLAB fuzzy logic toolbox. The simulation results suggest that fuzzy logic can serve as a complementary approach to mixed-method research by operationalizing qualitative criteria into computable models, handling the inherent vagueness and ambiguity in natural language. By translating fuzzy, context-dependent concepts into applicable models, fuzzy logic theory seeks to balance complexity with accountability, having significant implications for methodological rigor in applied linguistics research.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 3","pages":"Article 100278"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145415159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyses reveal significant methodological limitations that have hindered progress, including over-reliance on subjective assessments, inconsistent error categorization, limited participant representativeness, and lack of theoretical grounding. The research trajectory shows a shifting focus from comprehension in early studies to reader preferences in the 2000s, followed by renewed interest in communication effectiveness and the emergence of processing effort as a novel yet critical construct, despite the persistent dominance of subjective ratings. Recommendations for future research are proposed, including the potential theories to frame studies, adoption of direct and validated methods and shifting focus to non-teacher participant populations.

For each binomial, we obtained ratings of frequency, dispersion, forward association strength, and backward association strength from 34 human participants and from 30 output samples per LLM. We examined rating-to-corpus consistency (consistency<sub>rating2corpus</sub>), the sensitivity of statistical ratings to corpus data, and the influence of other psycholinguistic factors on ratings. All LLMs’ statistical knowledge broadly mirrored that of humans. Ratings from both groups were sensitive to corpus data but not fully consistent with it. Frequency showed the highest consistency<sub>rating2corpus</sub>, whereas dispersion showed the lowest consistency<sub>rating2corpus</sub> and the weakest sensitivity. LLM ratings were also influenced by word-level cues. Nonetheless, LLM ratings showed greater consistency<sub>rating2corpus</sub>, heightened sensitivity, and stronger reliance on other psycholinguistic cues than human ratings. Overall, while LLMs’ performance generally aligned with that of humans, their internal statistical representations differed significantly from human cognition. The three LLMs also showed variation in their rating behavior. Thus, although multi-LLM ratings can aid pilot studies in psycholinguistics, they should not replace human ratings in formal experiments.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 3","pages":"Article 100274"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145264725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Study 2, we build on the pilot by modelling follow-up data from a refined version of the study, focusing on the one treatment group only.

During the task, participants need to select a word that continues the sentence. Previous research has shown that both web-based data collection and the L-maze task are useful for investigating first language sentence processing. However, little is known about their usefulness for second language sentence processing research. To address this gap in the literature, I conducted replication experiments using the web-based L-maze and self-paced reading (SPR) tasks, and investigated whether these tasks could detect garden path and gender mismatch effects during the processing of locally ambiguous sentences. The results showed these effects in both tasks, with the effects being more localised in the L-maze task. A prospective power analysis suggested that these tasks would be effective for detecting these effects, and that the L-maze task would be more reliable than the SPR task for detecting gender mismatch effects.

Semantic prosody is a concept associated with corpus linguistics, which describes the tendency of seemingly neutral items to occur in particular evaluative contexts. In previous research on semantic prosody, there has been a heavy reliance on manual analysis of smaller samples, and because of this, questions have been raised about the stability of the established methods for categorisation. Furthermore, there is also a lack of consensus regarding how such categorisations should be operationalised. Traditionally, it has often been viewed in binary terms, distinguishing between <em>positive</em> and <em>negative</em> prosodies. However, this restricted system has also received criticism, and certain researchers have adopted a more comprehensive (or fine-grained) categorisation, more connected to a unit’s semantic preference. This paper aims to evaluate the inter-analyst consistency of these systems through two experimental studies, in which four researchers independently analyse the same set of random concordance lines of the items <em>habit</em> and <em>views</em> from BNC2014, applying both methods of categorisation. The results indicate that a binary distinction between <em>positive</em> and <em>negative</em> offers a higher inter-analyst consistency than a more fine-grained categorisation. Additionally, this more comprehensive system was also found to obscure the borders between semantic preference and semantic prosody. However, because neither system achieved satisfactory inter-rater agreement, both studies highlight the need for more objective methods of analysing and categorising semantic prosody.</div></div>","PeriodicalId":101075,"journal":{"name":"Research Methods in Applied Linguistics","volume":"4 3","pages":"Article 100264"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
