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.
