This project contains data and analyses reported in a paper "A gifted SNARC? Directional spatial-numerical associations in gifted children with high level math skills do not differ from controls" by Yunfeng He, Hans-Christoph Nuerk, Alexander Derksen, Jiannong Shi, Xinlin Zhou, & Krzysztof Cipora published in Psychological Research https://doi.org/10.1007/s00426-020-01354-9. Shared materials comprise: 1. Zipped file "gifted_snarc.zip" containing raw data from the parity judgment task along with all the data processing and analysis scripts. It allows reproducing SNARC and MARC slopes reported in the paper, and allows retracing all steps of the analysis conducted on the parity judgment task. All scripts are written in R programming language (freely available at https://www.r-project.org). Instruction on how to run the script can be found in the "README.txt" file included in the zipped file. Scripts themselves are also extensively commented. 2. Text file "gifted_snarc_combined_data.txt". This file can be opened in any spreadsheet / statistics program. It contains: 1. Demographic data of participants 2. RSPM (Raven Standard Progressive Matrices) scores 3. Scores in the multiplication task 4. Reaction time characteristics of the parity judgment task 5. Calculated SNARC and MARC slopes 3. JASP file "gifted_snarc.jasp" containing the data from "gifted_snarc_final_data_file.txt" and thoroughly annotated analyses, which are reported in the paper. Clicking on results of a certain analysis allows bringing it back, looking up settings, and modifying them. JASP is an open source software for statistical analyses freely available at https://jasp-stats.org. Please note that the file was prepared in JASP version 0.11, and it can be not compatible with previous JASP versions.
