how to set the variational value for the fixation

[EchoYang]

Hi there,

I'm programming an experiment, I want to set the value of "fixation" object among "300, 400, 500 ms", but I don't know how to write the inline to get this function.

If someone know how to do this, could you help me? thank you in advance!

Echo,

Why not just put those duration values in a List, then just refer to
that attribute from the List for the Duration of your fixation object?
E.g., make an attribute named "FixDur", and for Duration in your
fixation object use "[FixDur]". You might even do this as a nested List
-- see that tutorial in the Users Guide that came with E-Prime.

Hi David,

I thought this way, but I want the three value present randomly in 160 rows, so if I put those duration values in a list and then refer to that attribute, I don't how to make them totally random. Do you know?

Thanks!

Echo,

Yes. Use a nested List for your duration values. See the nested List
tutorial in Appendix C of the Users Guide that came with E-Prime.
Indeed, if you have not already, then please stop everything that you
are doing and first work through *all* of the tutorials in *all* of the
Guides that came with E-Prime. (I also show how to do this in my online
course.)

Best,
