===========================================================

This is the raw file as exported from LimeSurvey; the r notebook "cleaned_script" contains a section
"Create human readable participant demographics" which transforms this data into a human-readable format.

All the explanations below are referring to the result of this script.

_ FRS columns: 
All the columns starting with "FRS" are

The codes and the questions are detailed in file frs_questions.pdf.

The meaning of the resulting columns of this process is (note: all the columns starting with "FRS" are
answers to questions of the German language spatial strategies scale. Please refer to Table 1, p. 70 of:
