The trial file

  • The trial file is a simple spreadsheet with information about the trials and how you would like them to be. 
  • Each row is a trial (except the first row, which contains the column/parameter names) and each column is a possible parameter for that trial. 
  • A trial can have anything between three (e.g. type, stimulus, response) and over a hundred parameters. 
  • The list of all possible parameters/columns in a trial file can be found in the manual.
Many columns contain parameters used for both stimuli presentation and form questions (e.g. responseType), so you can easily switch between having an experiment or a form.

For forms, each row is a question.
