The feedback construct provides timed feedback for use in trials to indicate whether a participant's response was correct or incorrect. Feedback relies on rules specified in trials logic and only occurs at the end of a trial after either a response or a timeout.

Creating a feedback construct

Feedback constructs can be added to trials timelines. Click New item, select Feedback from the type list and select one of the following creation options:

  • New: create a new feedback construct.
  • Copy: copy another feedback construct from the current study.
  • Clone (from a different trial): clone an existing feedback construct from another trial.
