# Experiment 4: 2022/23 Replication of Field-Dependency and Cybersickness
# Study run by J. Josupeit, L. Greim, and S. Sanchez Rivas


The "VR_RFT_Input" folder contains 3 folders, 1 file and 1 Readme text file:

The 3 folders contain:

"VR_RFT_City" contains 1 folder, 82 data files, 1 R-script and 1 Readme text file:
   # the folder "VR_RFT_City_preprocessed" lists the preprocessed files for each participant, a large summary file and a Readme text file to explain the preprocessed files further
   # Unity-data for the City condition in 82 csv-files, the names contain the timestamp when the Unity application was initialized
   # "VR_RFT_Preprocessing_City.R" provides the code for preprocessing the City Unity-data for each participant and creating a large summary file of all
   # "VR_RFT_Readme_City.txt" describes the files and explains the variables in the data frames in detail   

"VR_RFT_Limesurvey" contains 4 data files, 1 R-script, 2 supplementary files, and 1 Readme text file: 
   # "VR_RFT_Codebook.xlsx" explains the variables used in the survey of "VR_RFT_Survey_Experimental_Protocol.csv" 
   # "VR_RFT_Data_Filtered.csv" contains the usable cases, a filtered version of the data from the survey
   # "VR_RFT_Data_Unfiltered.csv" contains the unfiltered data from the survey
   # "VR_RFT_Preprocessing_Limesurvey.R" contains the preprocessing of the LimeSurvey data 
   # "VR_RFT_Readme_Limesurvey.txt" explains the variables used in the survey in short form
   # "VR_RFT_Survey.lss" opens the original LimeSurvey questionnaire in the LimeSurvey app 
   # "VR_RFT_Survey_Experimental_Protocol.csv" contains the filtered version of the data combined with the experimental protocol
   # "VR_RFT_Survey_final.csv" contains the preprocessed LimeSurvey data

"VR_RFT_RFT" contains 1 folder, 81 data files, 1 R-Script and 2 Readme text files:
   # the folder "VR_RFT_RFT_preprocessed" lists the preprocessed files for 81 participants, 1 large summary file of all and 1 Readme text file that explains the preprocessed files further
   # 81 Unity-data csv-files for the virtual RFT condition, the names contain the timestamp when the Unity application was initialized
   # "VR_RFT_Preprocessing_RFT.R" contains the code for preprocessing the RFT Unity-data for each participant and creating a large summary file of all
   # "VR_RFT_Readme_special_cases.txt" explains the special cases for which the code for the preprocessing of the RFT data needs to be adapted
   # "VR_RFT_Readme_RFT.txt" describes the RFT Unity-data files and explains the variables in detail 

The file "VR_RFT_Experimental_Protocol_Index.xlsx" contains 2 sheets, which are 2 different versions of the experimental protocol for this experiment:

   # "Original" - the original German experimental protocol 
   # "English Translation" - the English translation of the experimental protocol

      the 2 versions of the experimental protocol contain the following information:
      VP-Nummer (participant number), Zufallszahl (random number), Bedingung 1 und 2 (condition 1 and 2 / indicates whether the RFT or City condition was experienced at first or second), Protokoll (protocol / comments of experimenter) and Index (index / data can be used without problems (=0), under certain circumstances/used with caution (=1) or cannot be used at all (=9))
