Requirements

Analysis are coded in R. The scripts rely on a fair number of R-packages, in addition to Stan for Bayesian analysis.

Setup

This repository uses the ProjectTemplate directory layout.

Data

Raw behavioural data is located in data/raw and is provided in .csv format. Demographics data are provided under the demographics folder. The export folder contains blinding related output, generated from the make_randomization_list.R, and Bayesian model outputs used for the manuscript (paper_vars.RData).

Preprocessing

First, load the library (library(ProjectTemplate)) and then load the project by load.project(). This will munge the raw data to a finished preprocessed output (see below), load the most relevant packages and other local packages.

Analyses

The analyses are located in the src/ folder as preregistered_analysis.R, exploratory_analysis, and descriptives.R.

In addition, a script related to fixes of errors in the data files can be found in fix_data_file_issues.R, and a power analysis for the study can be found in the power.R script.

Under the report/ folder there is a Quarto document used to generating the broad strokes for the results section.
