<h3>The effect of children's prior knowledge and language abilities on their statistical learning</h3> This paper has been published in Applied Psycholinguistics: <br> Stärk, K., Kidd, E., & Frost, R. L. A. (2022). The effect of children's prior knowledge and language abilities on their statistical learning. *Applied Psycholinguistics, 43*(5), 1045–1071. https://doi.org/10.1017/S0142716422000273. The study's preregistration can be found on AsPredicted: https://aspredicted.org/546hk.pdf. *Please find open materials and data below.* --- This project contains four main folders: Materials, Data, Analysis, and Dissemination, described in further detail below. Furthermore, it is linked to another project ("Close encounters of the word kind: Attested distributional information boosts statistical learning"), which is a related project conducted with German adults. For example, the stimuli of the current project were adjusted from the previous project with adults, so references to the previous project will be made where appropriate. --- **(1) Materials** This folder contains two subfolders: Stimuli and Presentation. The *Stimuli* folder contains a README file giving a short description of the files contained in this folder as well as a note on the stimuli creation explaining the coding in the Excel file. The folder further contains an Excel file outlining the creation of the stimuli and the randomisations, and four more subfolders. There is one subfolder for each sequence type as well as the practice trials. Each of these subfolders contains .wav files of the 24 sequences per type and the 6 practice trials, respectively. The *Presentation* folder contains the Presentation scripts in a .zip folder as well as a .pdf file showing the screens presented to participants (for quick access without having to run the experiment). --- **(2) Data** This folder contains a README file describing the files contained in this folder. It also contains two Excel files with the transcriptions of the participants' repetitions (one of the serial recall task and one of the sentence repetition task), another Excel file with the 10% reliability transcriptions (including both tasks), as well as two PDF documents with the respective coding schemes. --- **(3) Analysis** This folder contains a README file shortly describing the files contained in this folder. It also contains a PDF file giving a detailed description of the power analyses conducted for this paper. Finally, the folder contains an R project in a .zip folder, as well as .html files of the main analyses scripts (for more convenient, quick access): 1. power analysis 2. data preprocessing (coding) 3. data analysis 4. reliability analyses (task-internal & 10% inter-transcriber reliability) a. data preprocessing reliability coder b. reliability analyses 5. plot file combining adults' and children's data --- **(4) Dissemination** This folder will contain a PDF file of the talk we presented on this study.
