The trial Procedure (TrialProc) consists of a TextDisplay object (i.e., Fixation) used to present a
fixation prior to the stimulus display, an ImageDisplay object (i.e., Stimulus) used to present a
picture of a red car or a blue car, and a FeedbackDisplay object (i.e., Feedback) used to present
the appropriate feedback (i.e., correct, incorrect, etc.).
At run-time, the Stimulus object refers to the TrialList object in order to resolve the value for
Stimulus and CorrectAnswer.
The Feedback object organizes the feedback to be presented relevant to the input collected by
the Stimulus object.
Change the stimulus
The value of the Stimulus attribute may be changed by opening the TrialList and modifying the
values in the Stimulus column (names of the image files).
