Building on established indices, three new measures of accuracy, all linked to clause length, are described. In addition, variations in an error gravity formula are also used. The measures, both established and new, are trialed with an existing dataset from a study exploring planning effects on second language narrative performance. A range of established measures is shown to generate appreciable effect sizes with this dataset. The newly developed measures also work well, as do alternative error gravity formulae. The new length-accuracy measures also seem sufficiently distinct from measures of language complexity. We discuss the implications of these findings for measuring accuracy in task-based spoken language performance, as well as the relevance of the new measures for theoretical accounts of second language performance.","PeriodicalId":22008,"journal":{"name":"Studies in Second Language Acquisition","volume":"92 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In three preregistered experiments (N = 96 in Experiments 1a/b, and N = 160 in Experiment 2), we found that L1 and L2 real-time processing and final comprehension are constrained by crossover constraints. There was also no evidence for L1/L2 differences in the processing of crossover. These results suggest similar processes of structure building, structural prediction, and memory retrieval in L1 and L2 readers during sentence comprehension.","PeriodicalId":22008,"journal":{"name":"Studies in Second Language Acquisition","volume":"6 1","pages":"1-23"},"PeriodicalIF":4.1,"publicationDate":"2026-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148698801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many widely promoted open research practices, such as replication and preregistration, originated in response to the reproducibility crisis in psychology and map unevenly onto qualitative research. This critical review synthesizes literature from L2 research and neighboring fields to examine open research from a qualitative perspective. We organize the review around five key debates, including replication, preregistration, data sharing, data reuse, and publication policy. Taken together, these debates reveal the complexity of openness in qualitative inquiry and show both points of convergence and tension. We identify an emerging trend from principled resistance to principled engagement in the literature, with transparency standing out as a unifying principle. Building on these insights, we propose the situated-openness framework that serves as a heuristic for qualitative researchers to consider how to practice open scholarship in alignment with their own epistemological and ontological commitments.","PeriodicalId":22008,"journal":{"name":"Studies in Second Language Acquisition","volume":"36 1","pages":"1-19"},"PeriodicalIF":4.1,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148693474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dataset includes contrastive examples of three prosodic features: phrase boundary, disambiguating syntactic dependencies; contrastive focus, disambiguating key information within a phrase; and lexical stress, disambiguating word sense through syllabic emphasis, all recorded by three female and three male voice actors speaking Standard Southern British English. Researchers can tailor experiments by selecting stimuli isolating individual acoustic dimensions (e.g., pitch and duration) and by adjusting perceptual difficulty using samples with reduced acoustic information.

Although considerable attention is given to internal validity, external validity—the extent to which findings can be generalized beyond the specific study conditions—may be neglected during peer review and subsequent interpretations of findings. This editorial argues that a lack of attention paid to external validity reduces the interpretability and responsible use of SLA research through overgeneralization and misinterpretation of results. Current initiatives aimed at improving generalizability, including replication, meta-analysis, and multisite studies, are discussed, and a framework for evaluating external validity is proposed. The editorial concludes by calling for more transparent reporting practices and more cautious interpretation of research findings, with the aim of promoting accurate interpretation, replication, and theoretically motivated follow-up research in SLA.","PeriodicalId":22008,"journal":{"name":"Studies in Second Language Acquisition","volume":"33 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148393950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Learner interactions were coded for engagement (semantically engaged talk, responsiveness, LREs), while survey and interview data were analyzed using inferential statistics and thematic analysis. Our results showed that interaction mindsets predicted various dimensions of engagement (i.e., cognitive, social, and emotional) and lexical learning. Most learners viewed tasks positively despite their differing foci. Follow-up tests revealed the impact of task type on engagement, which in turn predicted task completion.

English-speaking participants were exposed to an artificial language with unfamiliar phonology and varying morphological salience. Results showed measurable acquisition of nouns and verbs, but limited learning of adjectives and case markers. Importantly, only participants in the high-salience condition showed sensitivity to morphosyntactic violations, suggesting that perceptual salience enhances awareness of grammatical structure. A word–picture matching task revealed that learners encoded phonolexical forms imprecisely: while clearly deviant items were rejected, minimally different lures were often accepted. Finally, individual differences in phonolexical precision were only weakly associated with phonetic discrimination ability. These findings demonstrate the power and limits of CSL in second-language learning and highlight the importance of perceptual cues for acquiring complex L2 structure.","PeriodicalId":22008,"journal":{"name":"Studies in Second Language Acquisition","volume":"47 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148291743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We confirm previous findings that monolinguals outperform bilinguals, and that the bilingual disadvantage is stronger for low- than for high-frequency items. While immersed bilinguals seem to have an advantage in L2 naming over non-immersed speakers, self-reported use of either language does not affect naming in either language, and the L1 is not affected by the immersed vs. non-immersed distinction.
