Paced Serial Addition Test (PSAT) Active Task Export Format

  • Updated
Follow

In the Paced Serial Addition Test (PSAT) Active Task, the participant is prompted with a digit (the "stimulus") every few seconds, each time adding it to the previous digit.

When your project uses the CSV export format for Survey Results, data for Active Tasks is exported in the file SurveyPSATResults.csv. When your project uses the JSON export format, Active Task data is included in the file SurveyResults.json.

For a typical survey using this task, you'll expect to see:

  • One survey result each time the participant completes the survey.
  • One step result representing the Active Task.
  • One PSAT result for that step. The individual prompts and responses are captured within that result.
