Trial file fundamentals

  • Each row is a trial. Note that the term “trial” is used in a broad sense; it refers to experimental trials, but also instructions screens. It also refers to questions in forms. 
  • Each column is a parameter. The columns have pretty self-explanatory titles. You can delete columns/parameter you don’t need (with the exception of the column “type” which is required). 
  • You can add any column/parameter described in this manual. In addition, you can invent new columns/parameters to help you organize your experimental design and your results (these columns will not impact what participants see, but will be recorded in the results file). 
  • The order of the columns is not fixed and columns can be reordered in any way.
