NWTKlearn README

Last updated AXL 20/09/2023

This is a README file documenting the NWTKlearn directory structure.

• data contains the raw form of the data, with a separate .csv file for each subject
• data_tidy contains the tidied form of the data, from various stages of the preprocessing and analysis scripts.
• experiment contains the files needed to run both studies 1 and 2. To run both experiments, open the study_1.html/study_2.html files with a web browser (right click > open with > e.g., Google Chrome). The other four folders (cues, jspsych-6.0.5, NWTKimg, and sounds) must be placed in the same directory as the html files.
• plots contains the figures outputted by the analysis scripts.
• scripts contains the R scripts needed to preprocess the data and run all analyses reported both in the main text of our manuscript, and the Supplementary Information.
  • Each study has a process script for preprocessing, and analyse script for analyses.
  • The process script for each study combines and cleans the raw data, outputting s1_data_cleaned.csv and s2_data_cleaned.csv. These files are then read in by the analyse scripts for analysis.
  • To run the scripts, first open the RStudio project nwtklearn.Rproj, then open the scripts inside the project session.

Study 1

An explanation of the choice variable in the data (after cleaning during preprocessing). Note that choice == 1 means the target option was chosen.

Choice Value	Info Cond	Option (stimulus)	Outcome
0	noninfo	square or triangle	optimal~120
1	noninfo	square or triangle	sub~80
0	info	KIS	optimal~120
1	info	FON	sub~80

Study 2

An explanation of the choice variable in the data (after cleaning during preprocessing). Note that choice == 1 means the target option was chosen.

Choice Value	Info Cond	Optim Cond	Option (stimulus)	Outcome
0	noninfo	sub	square or triangle	optimal~120
1	noninfo	sub	square or triangle	sub~80
0	info	sub	KIS	optimal~120
1	info	sub	FON	sub~80
0	noninfo	eq	square or triangle	~100
1	noninfo	eq	square or triangle	~100
