Stroop experiment, a number of issues to be resolved.

[Ben Meyers]

2.  To accomplish this you will have to adjust the frame size for all
of your text displays and then create an image display (whose frame
does not overlap the text displays ) with the rectangle for the bar
graph feedback.  Alternatively, (and the easier option imo) is to draw
the rectangle in an inline.  You can lookup Canvas.Rectangle in the E-
Basic help for that.  You can handle the reaction time checks in
another inline as well with "StimDisplay.RT"

3.  I don't know if this is exactly what you require based upon your
description, but I wrote up a guide for my lab about creating simple
menus in E-Prime so you can access which parts of an experiment that
you want.  I've copied it for you below at the end of my message.

4.  If you add a counter as either a global variable which you can
then increment simply by putting in an InLine counter = counter + 1,
or as an attribute in a list which you can then increment by

counter = CInt(ListName.GetCurrentAttrib("counter"))
counter = counter + 1
ListName.SetAttrib "counter", Cstr(counter)

you can check if the counter has been incremented up to the total
number of training trials and if not

goto LabelAtTheEndOfTheProcedure

Place your feedback display between this inline and the label.
