The FeedbackDisplay object named “Feedback” in the TrialProc organizes the feedback to be
presented in relation to the input collected by the Stimulus object.
Change the stimulus
The value of the Stimulus attribute may be changed by opening the TrialList object and modifying
the values in the Stimulus column. For example, the Stimulus might be changed to enter a
mathematical equation (e.g., 2 + 2). The value for CorrectAnswer may then be changed to reflect
the correct answer to the equation.
Add a mask
To add a mask to be drawn over the Stimulus, insert a TextDisplay object in the TrialProc timeline
after the Stimulus object. Enter the Mask text and set the duration in the properties for the new
object.
