generated during the compiling process, a message indicating the successful generate is
displayed in the Output window.
If errors occur during generation, an error dialog is displayed, and the error message is sent to
the Debug tab in the Output window. The error message will indicate the line in the script at
which the error occurred. In addition, the Script window opens to display the line at which the
error was encountered.
Luckily, compile errors are rare. However, this same debugging technique can be used when
run-time errors are encountered.
2.3.7.2 Run trials responding correctly, incorrectly and not
responding
Run the experiment to test the core procedure. Click the Run button to launch E-Run and run the
experiment.
It is important to test the limits of an experiment to ensure that it behaves desirably, and that
scoring is occurring correctly. As the experiment is specified in the current example, the “1” and
“2” keys are the valid input keys, and the stimulus display is set to terminate upon valid input.
First, it is important to run “normal” trials, responding both correctly and incorrectly in order to
verify that the valid keys are being accepted as input and that the display is terminating upon
response. If the subject presses a valid response key during the 2000ms display, the display will
terminate and the next trial will be presented.
