2.4 Stage 2: Elaborate the Trial Procedure
Note: This section builds on the experiment created during the previous section. A finished version of
LexicalDecision001.es is located in the C:\My Experiments\Tutorials\Using E-Studio Stages directory.
The goal of Stage 2 is to elaborate the basic Fixation-Probe trial procedure. A display will be
added at the beginning of the trial procedure to permit the subject to pace the trials and
instructions will be added to the Fixation display to remind the subject of the response keys.
Also, a Prime display will be added prior to the Probe display, and Feedback will be added to the
end of the trial procedure.
2.4.1 Add Get Ready display
Add a TextDisplay object as the first object in the TrialProc which allows the subject to set the trial
pace. Rename this TextDisplay to “GetReady.”
In the Text field, type “Press the spacebar when ready”. Allow the subject to begin the trial when
ready (i.e., set the duration to infinite by setting the duration to -1), enable keyboard input, and
enter the spacebar as the allowed input key. As a special key, the spacebar is entered as the
word "SPACE" (all capitals) surrounded by braces (i.e., {SPACE}). Set data logging to “standard”
to record subject wait time.
