2026-09-09 The Relationship Between the Use of Fillers and Japanese Proficiency: Focusing on OPI Level Assessment doi:10.57760/sciencedb.011ve en S1 Data. Learner background information. This file contains information on the native languages (L1s) and OPI proficiency levels of the 339 learners included in this study. S2 Data.  Analytic dataset for CLMM analysis (Tables 4 and 5). This file contains the underlying individual-level data used for the cumulative link mixed model (CLMM) analysis reported in Tables 4 and 5, including learner ID, L1, OPI score, and frequency counts for each filler type. S3 Data. The file summarizes the number of times each filler was used by each learner, as well as the total word count in the conversational data. S4 Code. R code for CLMM analysis (Tables 4 and 5). This file contains the R code used for the cumulative link mixed model (CLMM) analysis reported in this study, including data preparation, model fitting, and result extraction.  S5 Code.   This text file contains the R code used to calculate the Variance Inflation Factors (VIF) for the fixed effects in the CLMM analysis (Tables 4 and 5), along with the corresponding output. S6 Code.   R code for the minimal model (with output). This text file contains the R code used to refit the CLMM after excluding non-significant fillers, along with the corresponding output for the minimal model. S7 Data.    Analytic dataset for minimal model. S8 Code.   R code for likelihood ratio tests (with output). This text file contains the R code used to conduct likelihood ratio tests comparing the full model (reported in Tables 4 and 5) against the null model and the minimal model, along with the corresponding output. S9 Data.    Analytic dataset for Table 6. S10 Code.   R code for the CLMM analysis in Table 6 (with output). This text file contains the R code used for the CLMM analysis presented in Table 6, along with the corresponding output. S11 Code.   R code for VIF calculation for Table 6 with output. This file contains the R code and output for the VIF calculation corresponding to the model reported in Table 6. S12 Code.   R code for likelihood ratio test comparing the Table 6 model and the minimal model (with output). This text file contains the R code used to conduct the likelihood ratio test between the CLMM model reported in Table 6 and the minimal model, along with the corresponding output. S13 Fig 1.    Conceptual framework of the relationship between filler use and oral proficiency (corresponding to Fig 1 in the main text). S14 Fig 2.    Corresponding to Fig 2 in the main text. S15 Data.    Underlying data for Fig 2. S16 Fig 3.    Corresponding to Fig 3 in the main text. fillers use; OPI Level Assessment; usage; functions Chen Zuohao PUBLIC https://creativecommons.org/licenses/by-sa/4.0/ dataset Science Data Bank
