Randomization question.

[Matt Lenhart]

Hi Adam,

There are a couple of ways you can do this. The easiest would be to
use nested List objects. Essentially, you would create 5 List objects
that each represent a category. You would then enter the 8 words for
each category into their respective List. In your TrialList, you would
have 5 levels. Each level would reference one of these Lists under its
Nested column. Then, you would set the Weight column for each level to
4. At run-time, E-Prime will choose a stimulus from the specified
nested List object. The TrialList will run 20 trials (4 trials from
each of the 5 categories) and then exit. If the nested List objects
are set to select randomly (but without replacement), all 40 words
will be presented randomly and only 4 during each run of the TrialList
(i.e. you could use the same TrialList for each phase of the
experiment since it will run 20 trials each time).

Please let me know if you have any questions.
