----------
> **R scripts**
----------
- **Helper_functions.r:** An R script containing R functions needed to generate raw and summarised data as well as *VSM_report.rmd*. Run this script before you use any other R scripts in this file.
- **script to convert raw data into summary data.r:** Script to convert raw to all forms of summarised data (i.e. full dataset and exclusion subsets). "*NIrates.csv", "vsm-header.rsd", "VSM stim order.csv", "VSM Validation Study Final Raw.csv"* are all files used
- **VSM Validation study analyses script.r:** Script used to perform primary analyses and supplementary analyses reported in the manuscript.
"*Final_data_primary_analyses.csv", "Final_data_full.csv", "Final_.csv", "VSM Validation Study Final Raw.csv"* are all files used.
- **VSM_Report.rmd:** R markdown file used to generate a report of the data in table or figure format. "*Final_data_primary_analyses.csv", "Final_data_full.csv", "Final_.csv", "VSM Validation Study Final Raw.csv"* are all files used.
----------
> **Qualtrics**
----------
- **VSM_Validation_Study.qsf:** Qualtrics survey file of the survey format used in this validation study. This file can be imported into qualtrics when designing a new survey on the platform. NOTE: Survey is very large and is not optimal for Qualtrics. Expect to wait between webpages using this survey.
- **VSM_Validation_Study.pdf:** A pdf version of the entire qualtrics survey. Layout of survey: A Block (questions 1 - 10) B Block (Questions 1 - 10) [this format for the 52 sets] C block (questions 1 - 10) for each set.
