This site contains information about the Language 0-5 Project's Executive function paper which is published in Journal of Experimental Child Psychology. It contains: 1. the pre-registration (EF-SentenceProcessing_Preregistration_Final.pdf) 2. the manuscript (full.Paper.EF.docx) 3. Output (html) for the pre-processing analysis, the main analyses and the confirmatory factor analysis, with the following filenames: - Preprocessing: PreProcessing.V4.PostReview.OSF.html - Main analyses: MainAnalysis.V5.PostReview.OSF.html - CFA: CFA.V3.PostReview.OSF.html 4. A zipped file (AnalysisCode.Data.V5) containing the data and code necessary to reproduce the main analyses and the confirmatory factor analysis. This code is wrapped in an R project so it is necessary to download the zipped folder, unzip it and open the R project. The analyses were done with R version 4.0.4 (R Core Team, 2021). Filenames: - R project: EF.analysis.Rproj - Main analyses: MainAnalysis.V5.PostReview.OSF.Rmd - CFA: CFA.V3.PostReview.OSF.Rmd Note that we have only shared the output of pre-processing (i.e. we have not shared pre-processed data and code) because we do not have permission to share the raw data, which contains identifying information.
